Answer:
11,44,83
Step-by-step explanation:
4y+7y+6=116(exterior angle is equal to sum of two opposite interior angle in traingle)
11y=116-6
y=110÷11=11
4y=4×11=44
7y+6=7×11+6=83
Answer:
Total no. of cans and bottles = 920. One can weigh 14 ounce
Step-by-step explanation:
56x + 800
Answer:
y = three-halves x minus 3
Step-by-step explanation:
Subtract 3x from both sides of the original equation.
-2y = -3x +6
Divide by -2
y = 3/2x -3
8/343 = V = s^3
take the cube root of 8 and the cube root of 343 to get the side length
s= 2/7 ft
Answer:
144m²
Step-by-step explanation:
The the model made by Marie is attached in the diagram below.
The square pyramid model that Marie has in mind of building has 4 congruent triangular faces on the four sides of the square pyramid, and 1 base square. Therefore the surface area of the square pyramid = area of the square + area of 4 triangles = b² + 4(1/2*b*h)
Given that b = 8, and h = 5, we have:
Surface area = 8² + 4(1/2*8*5)
= 64 + 4(20)
= 64 + 80
SA of the square pyramid = 144m²
