Answer:
b. 8
Step-by-step explanation:
12/30 = x/20
x = 12/30 × 20
x = 8
The area of any triangle is (1/2) x (length of the base) x (height) .
In this problem, we know the triangle's height,
but what is the length of the base ?
The base is the side that the triangle is sitting on. This particular triangle
is an equilateral one, and its perimeter is 60m. So each side must be 20m.
No matter which side the triangle is sitting on, the length of the base is 20m.
Area = (1/2) x (base) x (height)
Area = (1/2) x (20m) x (17.3m) = <em>173 m²</em>
Answer:
icecream = $2.99
donut = $1.19
creamcake = $4.99
Step-by-step explanation:
The picture shows $7.17 for 2 x ice-cream and 1 donut
We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99
9.17- 4.99=4.18
=5.37-4.18 =1.19
we can then fill out the boxes.
1.19 +1.19 = 2.38 = 5.37-2.38= £2.99
2.99 +2.99 +1.19 = $7.17
We can see total first two rows = $12.56
2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56
Answer:
D
Step-by-step explanation:
The solution to a system of equations given graphically is at the points of intersection of the 2 graphs.
These occur at (4, 8 ) and (0, - 8 ) → D
