An artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. The width of the lake is 1/5 the length of the lake. What are the dimensions of the lake?

Answers

Answer 1
Answer:


We know that the area of a rectangle can be written as: length x width

so:

l x (1/5) = 9/20

9/20 x 5/1 = 45/20, which can be reduced to 9/4

So the length is 9/4 miles

The veterinarian weighed Oliver’s new puppy, Boaz, on a defective scale. He weighed 36 pounds. However, Boaz weighs exactly 34.5 pounds. What is the percent of error in measurement of the defective scale to the nearest tenth?Please help me :)

Answers

Answer:

4.3

Step-by-step explanation:

If your rounding to the nearest tenth them its 4.3. Don't listen to any of the other answers. They keep giving wrong answers. I tried to put 4 in because thats what the people on brainly said but it said I was wrong. I clicked show answer and it said 4.3. So everyone reading this...... its 4.3!!
new amount - original amount = amount of change

 amount of change/original amount × 100 = percent of change

-----------------------------------------------------------------------------

36 - 34.5 = 1.5

1.5/34.5 × 100 = 4%

Dominic and Stacy each have a stamp collection. Dominic has six fewer stamps than three times the number of stamps Stacy has. Dominic and Stacy decide to give all of their stamps to their younger sister, Mary. If Stacy had s stamps, which expression represents the number of stamps that Mary received?(3s - 18)(3s - 6)

2s - 18

4s - 6

4s - 18

Answers

The number of stamps that Mary received are 4s-6

What is linear equation ?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C"

Given,

Stacy has s stamps.

Then, from the question it is clear that Dominic has 3s-6 stamps

So, the number of stamps that Mary received will be 3s-6 +s = 4s-6

Hence, option C is the correct option.

#SPJ2

I'm pretty sure it's the first option.

Since Stacy has 3 times more stamps than Dominic does, you write 3s - 6
If you multiply 6 x 3 you get 18, giving you 3s - 18

Is 17/25 in decimal terminate or repeat?

Answers

Firstly we need to realize that 17/25 is as much as 68/100 (because 4 * 17 = 68 and 4 * 25 = 100). Now we can write it as a decimal of 0.68.

0.68 is a terminate decimal because there is no other digit than 0 we can add on its right hand side.
terminate because 17/25 is the same as 68/100 and that is 0.68. So, it is terminate

Jenna jump 156 inches in the long jump competition After High School track meet how many feet did Jenna jump

Answers

well lets think about it you need to make inches into feet 
if they are telling us the units in inches so if we know i foot has 12 inches we would have to divide 156 by 12
156/12 =13 
so that means she jumped 13 feet in long jump!
 13 feet hears how:
156/12=13

divide it

24+3x=3x+3(7-1) What does x equal? Please show me how to do it I don't want the answer. (Well I do but show me how to get it also pleaz) Lease help this is due tomorrow!

Answers


                                              24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses:    24 + 3x = 3x + 3(6)

                                              24 + 3x = 3x + 18

Subtract  3x  from each side:       24  =  18

Look at that for a second.  Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."
