Answer:

Table N 1

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In this problem the table N 1 represent a proportional relationship

Find the value of k

R/S=k

For R=5, S=1

substitute

tex]k=5/1=5[/tex]

For R=10, S=2

substitute

k=10/2=5

For R=15, S=3

substitute

k=15/3=5

For R=20, S=4

substitute

k=20/4=5

For R=25, S=5

substitute

k=25/5=5

the equation of the proportional relationship is equal to

R=5S

Assume that when you take a​ bath, you fill a tub to the halfway point. The tub measures 5 feet by 3 feet by 2.8 feet. When you
Irina18 [472]
Total water used while taking a bath is half the volume of water in tub.
Volume of water used=(volume)/2
=(5×3×2.8)/2
=42/2
=21 cubic feet

Total amount of water used while taking a shower will be given by:
Total amount of water=rate×time
=1.52×12
=18.24 gallons
Thus amount of water in cubic feet if there are 7.5 gallons in 1 cubic foot will be:
amount=18.24/7.5=2.432 cubic feet.

Therefore the conclusion is, the person is using more water in bathing than shower.

What additional information would prove each pair of triangles congruent by the HL Theorem?
SVETLANKA909090 [29]

Answer:

Please don't report me!

I don't know if this will help, but here is the definition of the HL theorem.

The HL Theorem states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

At what rate does a payment plan for $1,500 accumulate $450 interest after 6 years?
Lisa [10]

Answer:

At a rate of 5%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question:

Payment plan for $1500 means that P = 1500

$450 interest after 6 years means that E = 450, t = 6

We have to find the rate I. So

E = P*I*t

450 = 1500*I*6

I = \frac{450}{1500*6}

I = 0.05

At a rate of 5%.
