Find the perimeter and area the figure.
Answer:
Perimeter = 180
Area = 1080
Step-by-step explanation:
Perimeter is length of all sides added together. 30+78+72 = 180
Area is the length times the height/2 for a triangle. 30*72/2 = 1080

The length of Celia 's garden is 15m 24cm. The length of her friend's garden is 2m 98cm more than Ceila 's. What is the length of her friend's garden
Step-by-step explanation:
so, that means the friend's garden length is
15m 24cm + 2m 98cm
we can do this in 2 main ways.
1. using the fact that this is a metric system with 1m = 100cm.
15.24m + 2.98m = 18.22m = 18m 22cm
2. using fractions
15 24/100 m + 2 98/100 m =
= (1500 + 24)/100 + (200 + 98)/100 =
= 1524/100 + 298/100 = (1524 + 298)/100 =
= 1822/100 = (1800 + 22)/100 = 18 22/100 m =
= 18m 22cm
ultimately, they are both really using the same principles, but it looks a little bit different.

[tex]\longrightarrow[/tex] Let us know about definition of altitude first. The altitude of a triangle is the perpendicular line segment drawn from the vertex to the opposite side of the triangle.
[tex]\leadsto[/tex]Median is the line segment from a vertex to the midpoint of the opposite side.
Let us Check all options one by one
CD is line segment which starts from vertex C but don't falls on opposite side AB thus it is not an altitude.❌BA is line segment which starts from vertex B and falls perpendicularly on opposite sides AC and is thus an altitude.✔️AD is line segment which starts from vertex A and falls perpendicularly on opposite side BC and is thus an altitude.✔️AE is a line segment which starts from vertex A but doesn't falls perpendicularly on opposite side BC and is thus not an altitude.❌AD falls on BC with D as mid point because BD = CD and is thus a median. ✔️The function a(n) = 3(2)^n represents the value of the nth term in a sequence. What is the sum of the 1st and 4th terms of the sequence
Answer:
54
Step-by-step explanation:
We are given the sequence or function:—
[tex]\displaystyle \large{a(n) = 3(2)^n}[/tex]
To find the sum of 1st term and 4th term, first we must find the first term and the fourth term which can be done by substituting n = 1 and n = 4.
[tex]\displaystyle \large{a(1)=3(2)^1}\\\displaystyle \large{a(1)=3 \cdot 2}\\\displaystyle \large{a(1)=6}[/tex]
Then when n = 4.
[tex]\displaystyle \large{a(4) = 3(2)^4}\\\displaystyle \large{a(4) = 3 \cdot 16}\\\displaystyle \large{a(4) = 48}[/tex]
Therefore, the sum of 1st term and 4th term is:—
[tex]\displaystyle \large{a(1)+a(4) = 6+48}\\\displaystyle \large{a(1)+a(4)=54}[/tex]
The value of x if (5/7) * x = 10/7 so x =
Answer:
x = 2
Step-by-step explanation:
( 5 / 7 ) * x = ( 10 / 7 )
( 5 * x ) / 7 = ( 10 / 7 )
( 5 * x ) = ( 10 / 7 ) * 7
= ( 10 * 7 ) / 7
( 5 * x ) = 10
x = 10 / 5

y=6x+1
y+mx+3
Answer:
m = 6
Step-by-step explanation:
If the system of equations has no solutions, then the lines are parallel.
Parallel lines have the same slope.
The slope-intercept form of a linear equation is y = mx + b
(where m is the slope and b is the y-intercept)
Therefore, the slope of the equation y = 6x + 1 is 6
So the second equation should also have a slope of 6: y = 6x + 3
Now compare both
mx=6xm=6Hence m=6

Which of the following has a slope of 3 and y-intercept of 4
Answer:
see attached
Step-by-step explanation:
The slope is the ratio of the change in y to the change in x. The y-intercept is the function value when x=0.
__
A table demonstrates a y-intercept of 4 if the y-value for x=0 is 4. It demonstrates a slope of 3 if the y-value increases by 3 when the x-value increases by 1.
A graph demonstrates a y-intercept of 4 when the line crosses the y-axis at y=4. It demonstrates a slope of 3 if it rises 3 grid squares for each grid square it runs to the right.
The table and graph indicated in the attachment both show a slope of 3 and a y-intercept of 4.

Answer: x = 62.5 degrees
Step-by-step explanation:
Angle DEC is adjacent to the angle measuring 137 degrees, which means their sum is 180 degrees. Therefore:
Angle DEC + 137 = 180
We can subtract 137 from both sides:
Angle DEC = 43 degrees
We know that the sum of the angles in a triangle is 180 degrees, so we can set up an equation for triangle DEC.
We know Angle D + Angle C + Angle E = 180, so we can plug in the values given for each.
Therefore, x + 5 + x + 7 + 43 = 180
We can combine like terms:
2x + 55 = 180
Subtract 55 from both sides:
2x = 125
Divide both sides by 2:
x = 62.5 degrees

9. Given the circle below, find OR.
Answer:
A. 17
Step-by-step explanation:
Let X be the intersection of lines QR and NP.
By Power of a Point, we have [tex]QX\cdot XR=NX\cdot XP.[/tex]
(This can be proven with similar triangles by connecting QN and PR and using proportions with similar triangles [tex]\triangle QXN[/tex] and [tex]\triangle RXP[/tex].)
Plugging the values we know into [tex]QX\cdot XR=NX\cdot XP,[/tex] we have
[tex]12\cdot(x-2)=(3x-1)\cdot 3[/tex].
Dividing both sides by 3 gives
[tex]4(x-2)=3x-1.[/tex]
Distributing the left hand side gives
[tex]4x-8=3x-1.[/tex]
Subtracting 3x from both sides, we have
[tex]x-8=-1.[/tex]
Finally, adding 8 to both sides, we have
[tex]x=7.[/tex]
The question asks to find QR. (I'm assuming this is what you meant in the question.) With the lengths given, we know
[tex]QR=12+(x-2)=x+10.[/tex]
Therefore, plugging x in gives us

Four friends share the profit of a lawn care service equally. the friends charge $45 per lawn and spend $30 of their total earnings on gasoline for the lawnmowers each week. which inequality can be used to find m, the number of lawns they need to mow next week so that each person earns at least $275? startfraction 45 m minus 30 over 4 endfraction greater-than-or-equal-to 275 startfraction 45 m over 4 endfraction minus 30 greater-than-or-equal-to 275 startfraction 45 m minus 30 over 4 endfraction less-than-or-equal-to 275 startfraction 45 m over 4 endfraction minus 30 less-than-or-equal-to 275
Inequality can be used to find m will be 45m - 30 ≥ 1100. Inequality is an opinion of an ordering relationship between two digits or algebraic terms,
What is inequality?
inequality is a statement of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
The amount charged for lawn= $45
"m" is the total number of lawns they move per week. Because they charge $ 45 per lawn, the total amount they will charge for m lawns will be $ 45m.
Every week, they spend $ 30 of their whole earnings on gasoline. As a result, each week's total earnings will be
45m-30
Everybody wants to make at least $275. Because there are four of them, the total they aim to earn is at least
The total amount has to be earned for the four friends=4 x 275 = $ 1100
We need to figure out how many lawns they'll have to move in the following week to earn at least $1100. The equation is as follows:
45m - 30 ≥ 1100
This disparity may be used to find m, the number of lawns they need to mow next week to earn at least $275 for each participant. This can be solved in the following way:
45m ≥ 1130
m ≥ 25.11
We round up the number of lawns to 26 to guarantee they earn at least $ 1100 in total because the number of lawns must be a whole number.
we get m ≥ 26.
Hence inequality can be used to find m will be 45m - 30 ≥ 1100.
