X = number of MC questions
y = number of T/F questions
x+y=24
2x+6y=100
x=24-y
2(24-y)+6y=100
48+4y=100
y=13
x=24-13=11
Answer:
20 inches squared
This is because the area of a triangle is height times base divided by 2.
So it is 10*4/2, so the answer is 20 inches squared.
Answer:
350 sq ft
Step-by-step explanation:
Given that:
840 sq ft area has a bedroom, kitchen and bathroom.
Let the area of bedroom be
sq ft.
Then the area of kitchen will also be
sq ft.
Let the area of bathroom be
sq ft.
As per question statement:
![x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)](https://tex.z-dn.net/?f=x%2By%2Bx%3D840%5C%5C%5CRightarrow%202x%2By%3D840%20......%20%281%29)
Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.
i.e.
![2x+2y=980 ..... (2)](https://tex.z-dn.net/?f=2x%2B2y%3D980%20.....%20%282%29)
Subtracting equation (1) from (2):
i.e. (2) - (1):
sq ft
Putting the value of
in (1):
![2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}](https://tex.z-dn.net/?f=2x%2B140%3D840%5C%5C%5CRightarrow%202x%20%3D700%5C%5C%5CRightarrow%20%5Cbold%7Bx%3D350%5C%20sq%5C%20ft%7D)
Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
If goal post is rectangle shaped then u can see distance of bc base is 3 times of its sides(distance from top to ground)(imagine aectangle)
So let x be the distance so bc=3x
Perimeter is given now u just put values in a formua of perimeter
