A rectangular prism is 4 meters long, 5 meters wide, and has a height of 7 meters. What is its surface area?140 m 2
166 m 2
84 m 2
70 m 2

Answers

Answer 1

Answer:

Answer:

The surface area of rectangular prism is 166 m².

Step-by-step explanation:

Given that,

length l= 4 m

Width b= 5 m

Height h=7 m

Using the formula of surface area of rectangular prism

$A= 2(bh+lb+lh)$

We substitute the value into formula

$A= 2(5*7+4*5+4*7)$

$A= 2(35+20+28)$

$A=2*83$

$A= 166 m^2$

Hence, The surface area of rectangular prism is 166 m².

Answer 2

Answer:

Answer:

166 m^2

A game spinner has regions that are numbered 1 through 8. if the spinner is used twice, what is the probability that the first number is a 3 and the second is a 6? a. 116 b. 164 c. 964 d. 23

Answers

The probability that the first number is a 3 and the second is a 6 is 1/64

What is probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given:

spinner had region numbered from 1 to 8

So, the probability on the spinner has an equally likely chance of being selected = 1/8.

P(3) = 1/8

P(6) = 1/8

Thus, probability that the first number is a 3 and the second is a 6

= (1/8) × (1/8)

= 1/64

$(9x - 15)/(4) = x$ / * 4 (both sides)
9x - 15 = 4x / - 9x (both sides)
-15 = -5x / ÷ (-5) (both sides)
x = 3

(9x-15)/4=x /*4...... 9x-15=4x........ 5x=15........ x=3

If a car travels 340 miles on 20 gallons of gas how far can it travel on 25 gallons of gas

Answers

First, divide 340 miles by 20 gallons of gas, to see how many miles you have per gallon. 340 divided by 20 = 17 mpg. Next you multiply 17 mpg by 25 gallons of gas to see how many miles you can go.
17 times 25 = 425 miles. Your answer is 425 miles.

Let P(x) = F(x)G(x) and Q(x) = F(x)/G(x), where F and G are the functions whose graphs are shown.(a) Find P '(2). (b) Find Q'(7).

Answers

Hello,

Very nice like question!

a)
F(2)=3 ; G(2)=2
F'(2)=0; G'(2)=1/2
P'(x)=F'(x)*G(x)+F(x)*G'(x)

P'(2)=0*2+3*1/2=3/2

b)
F(7)=5; G(7)=1
F'(7)=1/4; G'(7)=-2/3

Q'(x)=(F'(x)*G(x)-F(x)*G'(x)) / G²(x)

Q'(7)=(1/4*1-5*(-2/3))/1²=1/4+5/3=23/12
