What is the surface area of the following prism?
Stolb23 [73]

Answer:

102cm²

Step-by-step explanation:

Surface Area = BH +Lp

B is the base area

H is the height of the Prism

L is the slant height

p is t perimeter of its base

B =1/2 ×3×4

B= 6cm²

H = 7cm

L = 5cm

P = 3cm+4cm+5cm

P = 12cm

Substitute

TSA = 6(7)+5(12)

TSA = 42+60

TSA = 102cm²

Hence the total surface area of the shape is 102cm²

What is the simplest form of 8m - 5n + 2m + 6n
Ivenika [448]
8m - 5n + 2m + 6n =Simplifying 8m + -5n + 2m + 6n = 0 Reorder the terms: 8m + 2m + -5n + 6n = 0 Combine like terms: 8m + 2m = 10m 10m + -5n + 6n = 0 Combine like terms: -5n + 6n = 1n 10m + 1n = 0 Solving 10m + 1n = 0 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1n' to each side of the equation. 10m + 1n + -1n = 0 + -1n Combine like terms: 1n + -1n = 0 10m + 0 = 0 + -1n 10m = 0 + -1n Remove the zero: 10m = -1n Divide each side by '10'. m = -0.1n Simplifying m = -0.1n.

You are playing a new video game. The table shows the proportional relationship between the number of levels completed and the t
Lana71 [14]

The time to complete 2 levels is (c) 60 minutes

<h3>How to determine the time to complete 2 levels?</h3>

The table of values is given as

Number of Levels     Time (hours)

2                                         ?

3                                         1.5

Express the blank (?) with y

Number of Levels     Time (hours)

2                                          y

3                                         1.5

The ordered pairs from the table are

(x, y) = (2, y) and (3, 15)

The table shows the proportional relationship

This means that the equation can be represented as

y = Y/X * x

Where

(x, y) = (2, y)

(X, Y) = (3, 1.5)

So, we have

y = 1.5/3 * 2

Evaluate the quotient

y = 0.5 * 2

This gives

y = 1 hour

Convert to minutes

y = 60 minutes

Hence, the time is 60 minutes
