Answer:
The regular price of the balls is $8
Step-by-step explanation:
The sporting goods store sales promotion is as follows;
The price of the third ball after buying two balls at regular price = $1.00
The price of the number of balls Coach John pays for the balls he bought = $136
To buy 24 balls, we have;
2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1
Therefore;
The number of balls bought at regular price = The sum of the 2s = 16 balls
The number of balls bought for $1 = 24 - 16 = 8 balls
Let x represent the regular price of the balls, we have;
16 × x + 8 = 136
16·x = 138 - 8 = 128
x = 128/16 = 8
The regular price of the balls = x = $8.
Answer:
answer is B
Step-by-step explanation:
Answer:
3rd Option: -1(x + 15)
Step-by-step explanation:
When we factor our a negative 1, we take the opposite signs of what is given:
-1(x + 15)
To check, we simply just redistribute to check if it matches the original expression:
-x - 15
So the 3rd option is the correct choice.
Answer:
The answer is A. 755 m2; 815 m2
Step-by-step explanation:
The answer is A) 472m^2; 486 m^2.
Let a, b, and c be the sides of the base and h be the height of the prism
a = 2 m
b = 7 m
c = 7.28 m
h = 29 m
The lateral surface area is:
LA = a*h + b*h + c*h = h * (a + b + c)
LA = 29 * (2 + 7 + 7.28) = 29 * 16.28 ≈ 472 m²
The surface area is:
SA = LA + 2 * 1/2 * a * b
SA = 472 + 2 * 7 = 472 + 14 = 486 m²
Answer:
14°
Step-by-step explanation:
Both angles are vertical angles and are opposite, hence, from angle theorem., vertically opposite angles are equal :
Angle EGD = Angle FGH
Angle EGD = (4x + 8)
Angle FGH = 64
HENCE,
4x + 8 = 64
4x = 64 - 8
4x = 56
x = 56/4
x = 14°
