Answer:
145 yd²
Step-by-step explanation:
There will be dour triangular faces. For a triangle, area is given as
A=½bh where b is base and h is height. The base will be 5 yards and h is 12 yards hence for one triangular face, area will be ½*5*12=30 yd²
Since they are four similar triangles, area of triangular faces will be 30*4=120 yd²
The surface area of a square base is given by
A=a*a=a² where a is the dimension of one side. Given that the meaurement is 5 yards then A=5²=25 yd²
Total area will be the sum of triangular and square faces hence 120+25=145 yd²

Answer:
Step-by-step explanation:
If apricots is x, and each apricot weighs 5 grams, then the expression for that is 5x; if each cherry, y, weighs 2 grams, then the expression for that is 2y. If the mix Roy wants to make needs AT LEAST 230 grams of fruit, then
5x + 2y ≥ 230 where the inequality sign "greater than or equal to" satisfies the expression "at least".

Answer:
7 ⁻²²
Step-by-step explanation:
7¹⁶/7¹² = 7⁻¹⁸/7ˣ
7⁽¹⁶⁻¹²⁾ = 7⁽⁻¹⁸⁻ˣ⁾
16 - 12 = - 18 - x
4 = - 18 - x
x = - 18 - 4
x = - 22
