twelve and three tenths more than five and thirteen thousandths of a number d is equal to fifteen and three hundred two thousandths. what is the value of d?

Answers

Answer 1

Answer: 12 3/10 (12 3/10) more than (+) 5 13/1000 of a number d (5 13/1000d) is equal to (=) 15 and 302/1000 so

we want the bottom numbers the same so

12 and 3/10=12 and 300/1000
5 and 13/1000 is the same
302/1000 is the same so

12 300/1000+5 13/1000d=15 302/1000
subtract 12 300/1000 from both sides
5 13/1000d=3 2/1000
5 13/1000d=5013/1000d
3 2/1000=3002/1000
5013/1000(d)=3002/1000
multiply both sides by 1000/5013 (to make it a one exg 1/2 times 2/1=2/2=1)

d=3002/5013 times 1000/1000=3002/5013≈0.59843

It's prime because the constant term is positive and there is no middle term. If it were x^2 - 16, we could use (x+4)(x-4), but because 16 is positive, it cannot be factored

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:

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:

166 m^2
