Answer:
the answer is D. 7 1/30
Step-by-step explanation:
first make them into improper fractions:
21/5 and 17/6
second find a common denominater (im using 30) and multiply so they have 30 as the denominater:
126/30 and 85/30
third add the improper fractions:
126/30 + 85/30 = 211/30 and as a mixed number it would be 7 1/30
Answer:
D. 7 1/30
Step-by-step explanation:
4 1/5 + 2 5/6=
The first thing we notice here are the fractions, whenever working with fractions, the first thing to do to make your life easier is to find the common denominator for the fractions. What's a common denominator?? a common denominator is when two fractions can have the same number on the bottom. We know that 5 times 6 gives you 30, so 30 can be our common denominator.
4 1/30 + 2 5/30 =
ok so, we changed our denominator, but now what? since we changed the denominator, this also affects the numerator (the numbers on the top). to fix this, we have to do the same to the numerator as we did to the denominator. to change 5 into 30, we multiplied it by 6, this means we also have to multiply 1 by six, 6/30. Don't forget the other fraction too! Since we multiplied 6 by 5 to get 30, we also have to multiply 5 by 5, 25/30.
4 6/30 + 2 25/30 =
now that the fractions have the same denominator, we can just go ahead and add the digits and numerators!
we know that 4 + 2 = 6, so we can remove them and put 6 at the end of the equation
6/30 + 25/30 = 6
but we aren't done yet, now we add 6 + 25 which gives us 31, out of 30
wait! 31/30? that doesn't sound right. 30 out of 30 automatically gives us a 1, so we can add that to the 6 we got earlier, 6 + 1 = 7. Since we are left with 1/30 we will add this to the final answer: 4 6/30 + 2 25/30 = 7 1/30
what is the area of a quadrilateral a right-angled triangle placed over an inverted equilateral triangle with length of 6 ft the length of the perpendicular side is the length of the perpendicular from the vertex of equilateral triangle
Answer:
To find the height we divide the triangle into two special 30 - 60 - 90 right triangles by drawing a line from one corner to the center of the opposite side.

This table of values represents a linear function. Enter an equation in the form y=mx+b that represents the function defined by this table of values
Answer:
y=-2x+3
Step-by-step explanation:
m = slope = y/x = -4/2 = -2
b = y intercept = 3
Answer:
f(x)=-2x-4
Step-by-step explanation:
First of all, I want to say that I'm a 5th grade kid, and I'm studying linear functions in eight grade. The equation is f(x) = mx + b. The b is y intercept. Since the y is -1, we know that f(x)=mx+-1, or f(x)=mx-1. Then, we look that the x. It's 2. Then, substitute 2 for m. F(x) = 2x-1. I'm gonna do the other ones. f(x)=4x-5, f(x) = 6x-9. We know that the x is substracting 2. The y is subtracting 4. So the rule is f(x) = -2x-4

x = 0 is a vertical line.
If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.
Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

BRAINLIEST PLEASE ANSWER FAST THIS IS MY SECOND TIME REPOSTING THIS I WILL GIVE BRAINLIEST!
In the following figure, triangle ABC is a right triangle, and m∠A = 38°. Find the value of n°. Note: the figure is not drawn to scale.
138°
128°
142°
52°
BTW THERE IS NO 132!
Kind note:
I am sure that the triangle you meant was in the image attached. I will find n in the image I attached.
Solution:
We know that:
∠B = 90°∠A = 38°Sum of interior angles of a triangle = 180°Step-1: Find ∠C.
∠A + ∠B + ∠C = 180°=> 38 + 90 + ∠C = 180°=> ∠C + 128 = 180°=> ∠C = 180 - 128 = 52Step-2: Find n.
52 and n are a linear pair.
52 + n = 180=> n = 180 - 52=> n = 128Choose all correct answer choices if u are right I will mark u as brainliest

-14/ -7/5 = u
u = -14 (5/-7)
u = -70/-7
u = 10
-7/5 (10) = -14 ?
-70/ 5 = -14 ?
-14 = -14

1. 83.6
2. 24
3. 95/2
4. 3
5. 30
6. 84.5
Step-by-step explanation:
Answer:
area is just multipling the base and the height.
ˆ2 means squared
Step-by-step explanation:
1) 7.6 is the height and 11 the base, so the area would be 83.6cmˆ2
2) there is a triangle but to find the area we divide it into 2 parts. first lets get the measurments settled, we can see that the height is 4ft, and the triangle on the left we can see that the base is the same size as the height, look at the image i attatched if you dont understand how i am explaining it. but we know that the total size of the base is 12, right? well if we subtract the 4 ft from the left triangle we are left that the right triangle has the size of 8ft for base and 4ft for height, if we multiply we have 32ftˆ2 but its a triangle so remember we have to divide this answer by 2, giving us the first area of 16ftˆ2. now we move onto the left triangle, 4 from the height x 4 from the base gives us 16cmˆ2 same as before we divide by two which gives us for the second area 8ftˆ2, now we add both areas we obtained, giving us the area for the whole figure which is, 24ftˆ2
3) for this one we will divide it into 3 parts, look at the image attached, for the steps
4) Ahhh! fractions, dont be nervous these are easy peasy, we know the base is 4in and the height is 3 1/2in. lets convert the fraction into decimals so its easier, so now we have 3.5 as height and 4 as base, we multiplay them which will give us 14inˆ2 since its a triangle we have to divide by 2! our answer will be 7inˆ2
For 5 and 6 look at the image :]
