c) Combine 2+3 to get 5. 100-(5x5) equals 100-25. 100-25 is 75. The answer is 75.

d) Combine 2+3 to get 5. Combine 1+4 to get 5, which is 25. The answer is 5.

g) Combine 4+6 to get 10. Combine 70+-6 to get 64. Take the root of 64, leaving you with 10-8. Combine 10 + -8 to get 2. The answer is 2.

h) Combine 5+4 to get 9. Take the root of 36, leaving you with 18 + 6.  Combine 18 + 6 to get 24. The answer is 24.


5. [15 + 22 + 53] divided by [12 + 18] = [90] divided by [30] = 3 ribbons each.

6. (4 x 12) + (6 x 8) = 96 total.

MATH!!! 15 points ;)) find the volume of the composite figure
andrezito [222]

Answer:

(2*2*1.5*1/3)+(2*1.5*4)= 14

Step-by-step explanation:

To find the area of a pyramid, you use the equation of 1/3 *lwh. When we place the values in there, we get 2*2*1.5*1/3, which is equal to 2. Then we solve the bottom part. Since it is a rectangular prism, we use the equation of lwh. When we insert the values, we get 2*1.5*4, which is equal to 12. Now, we take these two values of 2 and 12 and we combine them, giving us our final answer of 14.

Sarah is rolling a number cube, numbered 1-6, and recording the number that shows up on each roll.
Fiesta28 [93]

Answer:

C

Step-by-step explanation:

Definition: Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.

Event A = getting a 4 on the first roll.

Event B = getting a 4 on the second roll.

True option C: A and B are independent events, because the probability of the first roll will not affect the probability of the second roll.

A convex polyhedron has (a + 3) faces, (2a) vertices, and (4a – 1) edges. What is the value of a? a =
rusak2 [61]
Number of faces: F=a+3
Number of vertices: V=2a
Number of edges: E=4a-1

V+F-E=2
Replacing V=2a; F=a+3; and E=4a-1 in the formula above:
(2a)+(a+3)-(4a-1)=2
Eliminating parentheses:
2a+a+3-4a+1=2
Adding similar terms:
(2+1-4)a+(3+1)=2
(-1)a+4=2
Solving for a. Subtracting 4 both sides of the equation:
(-1)a+4-4=2-4
(-1)a=-2
Dividing both sides by (-1)
(-1)a/(-1)=-2/(-1)
a=2

Answer: The value of a is: a=2
