Step-by-step explanation:
Each grid is divided into units by the dark vertical lines, and into fractions of the last unit by the lighter vertical lines. The left-side figure, for example, shows 3 units, the last of which is divided into fourths (1/4s).
The lighter horizontal lines divide the vertical space into fractions. The left side figure has horizontal lines dividing the vertical space into tenths (1/10s).
Overall, each grid represents multiplication of a mixed number by a fraction.
__
The left-side figure has coloring horizontally covering two full units and 3/4 of the last unit. The coloring vertically occupies 3 of the 10 spaces, Overall, the figure represents multiplication of 2 3/4 by 3/10. That matches the solution required for the question about July rainfall (bottom word problem).
__
The top right figure has coloring horizontally that covers two full units and 2/3 of the last unit. The coloring vertically occupies 2 of the 3 spaces. Overall, the figure represents multiplication of 2 2/3 by 2/3. That matches the solution required for the question about mat area (top word problem).
__
The bottom right figure has coloring horizontally that covers three full units and 1/5 of the last unit. The coloring vertically occupies 1 of the 4 spaces. Overall, the figure represents multiplication of 3 1/5 by 1/4. That matches the solution required for the question about the weight of carrots (middle word problem).

Additional comment
Perhaps the confusing part is that the answer to the question, as represented by the shaded area, is not easy to determine from the figure.
The left-side figure, for example, has a blue shaded area that totals 6/10, and an orange shaded area that totals 9/40. The answer to the question posed is then 6/10 +9/40. The diagram offers no help in figuring the value of that sum, hence the answer to the question.

Date : . The perimeter of Kite LIKE is 80 cm. The length of LI is 6cm less than Length of IK. Find the length of each side?
Answers
Answer:
lK = KE = 23cm
LI = LE = 27cm
Step-by-step explanation:
perimeter of kite LIKE =80cm
If IK=x cm
LI=(x-6) cm
Perimeter =2(a+b)
80 = 2(x+(x-6))
80 = 2(x+x-6)
80 = 2(2x-6)
80/2 = 2x-6
40 = 2x-6
2x = 40+6
2x = 46
x =46/2
x = 23
therefore,IK = 23cm

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ?
Answers
Answer:
168 km
Step-by-step explanation:
1 hour = 60 minutes
⇒ 5 hours = 5 × 60 = 300 minutes
We have been told the distance that the car traveled in 25 minutes.
Therefore, divide 300 minutes by 25 minutes:
[tex]\implies \sf \dfrac{300}{25}=12[/tex]
So there are 12 'lots' of 25 minutes in 5 hours.
Therefore, to find out how far the car travels in 5 hours, multiply the distance traveled in 14 km by 12:
⇒ total distance = 12 × 14 = 168 km
25min=25/60=5/12h

Find the measures of the interior angles of the triangle. Find A, B, C
Answers
Step-by-step explanation:
I am not sure what you mean by A, B, and C.
the picture does not name the corners or vertices.
but is seemingly asks for the angle x.
remember, the sum of all angles in any triangle is always 180°.
and the sum of all angles around one point on one side of a line is also 180° (as the line cuts a virtual circle in half with its center being the point around which the angles rotate).
when we know all angles except for one, we call the missing angle a supplementary angle (fills up to 180°).
if the angle fills up to 90°, we call that a complementary angle.
so, now look at the triangle. we know 2 angles : the right angle (90°) and the 38° angle.
so, the third angle down left must be
180 - 90 - 38 = 52°
and x is the supplementary angle to 52° :
x = 180 - 52 = 128°

Michael has x dollars saved. John has $18 more than Michael. Their friend Ian has $2 less than two-
thirds that Michael has. The total amount of money they have is $272. How much does Michael
have?
Answers
Answer:
$96
Step-by-step explanation:
Micheal's money = x
John's money = y
Ian's money = z
x + 18 = y
2/3x - 2 = z
x + y + z = $272
rearrange the equations we have:
2/3x = z + 2
x = 3/2(z + 2)
x = y - 18
Substitute y - 18 into x values:
3/2(z + 2) = y - 18
y - 18 + y + z = 272 --> 2y - 18 + z = 272
Solve for y:
Firstly rearrange
2y - 18 + z = 272 --> z = 272 + 18 - 2y, which simplifies to z = 290 - 2y
substitute into the formula:
3/2((290 - 2y) + 2) = y - 18
3/2(292 - 2y) = y - 18
438 - 3y = y - 18
4y = 456
y = $114
Substitute back into the formula to find z:
z = 290 - 2(114)
z = 290 - 228
z = $62
Put all of this back into one of the original formulas to find x:
x + y + z = 272
x + 114 + 62 = 272
x + 176 = 272
x = $96
Total amount = $272
Now, ATQ[tex] \tt \nrightarrow \: x + 18 + x + 2 - \frac{2}{3} x = 272[/tex]
[tex] \tt \nrightarrow \: 2x + 20- \frac{2}{3} x = 272[/tex]

[tex] \tt \nrightarrow \: 4x = 756[/tex]
[tex] \tt \nrightarrow \: x = 189[/tex]

As you can see, I have my subsidies trying out and, like, a lot of time president focused on assessing. Okay, so we need to figure out what seat for the size that we're giving you could put them in any order you want. So we're gonna try this order for us, and then we're gonna try. So we're gonna do you know that the inside of the a softly triangle in this out of this triangle are equal to each other. And when you add them together, there has to be greeted with this out of this. Had a trying. So we're first gonna do three t is equal to five t oneness. Well, arguments of drugs five from both sides fascinate this negative to t is equal to negative. After this, we could divide negative to on both sides to find out what see is to get T bites so tracked, divided by negative tune. And then we're gonna do t is equal to negative 12 of our negative to 6 36 So we're going to check our solution by plugging in six. So when we plug six into this equation, we're gonna gate 18 3 times six is 18. And when we plug six into this equation, we're gonna get five times six, which is dirty five times six is 30 and you're going to subtract. Told him 30 that gave to. And then we're gonna put 6 40 and we're gonna add it to Tony, which is 26. And then after this, we're gonna add these two 18 18 to figure it out if it's hired into 6 18 plus 18 is 36. So it's harder 26 c is equal to is equal to six. Like I said before, this is not the only order because switch up the sides with them in different places. So I'm gonna take away this side. I took a week this, and I'm gonna put I want to take with this ad too, and I'm in. I'm gonna put t this 20 this side and five C minus. Whoa, This Okay, so we're gonna do the same thing we did over here. We're gonna do three t is equal to C plus 25 because these two sides great. See? Do you see before? See e waas 20 first. We're going to subtract C from both sides we're gonna get to t is equal to finding. And then we're gonna divide to from both sides to get by itself. And, uh, an anti is equal to 10 because 20 the bottom right to it. So we also know that he gave me 10. So we're gonna plug 10 in today, San plus 10 times their times three is equal to this is dirty. And we also know we're gonna put 10 for this side. A tent was 20 is dirty also, it's an end times what? It's 50 When you subtract well, you get 36. No, you get 30 feet, you get 38 when you add 30 plus dirty is 60. So this works. So t is also equal to 10 and we're gonna switch up the order again. This sound this one, I believe this one. And also as you know, we're switching at the side, trying all the possible leads with right. Let's go drop this trying. So this side now will be treaty. And this I will be five c minus slow. We're gonna go. We're gonna do five minutes. 12 is equal to 10 is equal city plus 20 because we know these two sides has equal five feet on its 12. I just love equal See loose. Okay, As you can see, we're going to subtract, see from both sides. And I was going to or C and I'm going to do two steps at a time for gonna actual on this side to everything this tool to get rice on one side of the equation. So I'm gonna add so so both side, and it's gonna before C is equal to dirty, too. We're gonna divide both sides by four to get see bites. So four divided by 36 is line for teeth equal to nine. We're gonna plug that incident equation tee. Times five is nine times five is 45. We're gonna subject for from him that is equal to 32. 33 and then we're gonna do nine waas 20. So amid a misty 2012 is actually 32. So these so t is actually equal to eight because three times 32 divided by four is eight. And we're gonna redo this one because so eight times five is 40 eight times five is sporting. And when we take away Whoa. 40 minus 12 is 28 is doing a So we're gonna do and we're gonna put in April. See here too. This is gonna be a plus 20 which is 28. We're gonna plug in eight for decide eight times three is 24 24. And as you see, this is obviously lower. It's gonna be lowered, indecent. Act together. So, you know, seek and also equal to eight. So for the sausages triangle there. Three possible answers for teeth, depending on how you put the sides which side before, which in just it depend on how you put your sides for the collateral. We know that all of the size has to equal to one thing. And from this, the signs don't equal the same thing One of them is You could get two of them to equal to each other so you can get rid of the size to be able to the same thing. So for the equilateral triangle, it's not possible. So not

luke drives 35 mph for 5 miles. he then drives 80 mph for 30 seconds (0.0082 miles). what is his average speed?
ik the answer i just need to know how to do it
the answer is 55.56 mph
Answers
Answer:
Step-by-step explanation:
Average speed is total distance divided by total time.
The relation between time, speed, and distance is ...
time = distance/speed
Total timeThe time to travel 5 mi at 35 mi/h is ...
time = (5 mi)/(35 mi/h) = 1/7 h
30 seconds is (30 s)/(3600 s/h) = 1/120 h, so the total time for this trip is ...
1/7 +1/120 = (120 +7)/840 = 127/840 hours
Total distanceAt 80 mph, the distance traveled in 1/120 hour is ...
distance = speed × time = (80 mi/h)(120 h) = 2/3 mi
So, the total distance traveled is ...
(5 mi) +(2/3 mi) = 17/3 mi
Average speedThe average speed is then ...
speed = distance/time
speed = (17/3 mi)/(127/840 h) = 17·840/(3·127) mi/h = 37 61/127 mi/h
The average speed is about 37.48 miles per hour.
_____
Additional comment
In order for the average speed to be 55.56 mph, the time spent at 80 mph would need to be about 7 minutes 12.6 seconds, for a distance at 80 mph of about 9.61 mi.
