f = 5x - 2y x = 3 and y = −2 Find the value of f

Answers

Answer 1

you just replace the letters so its going to be

f=5x- 2y                          with x=3  ,   y= -2

f=5·3 -2 (-2)

f=15+4=19

Answer 2

Answer:

f=19

Step-by-step explanation:

f=5x-2y

when X=3 & y= -2

or, f=5×3 - 2×(-2)

or,f=19

A dishwasher uses 11 liters of water for each cycle. A washing machine uses 5 times as much water as a
dishwasher uses for each load. Combined, how many milliliters of water are used for 1 cycle of
each machine?

Answers

Answer:

55,000 milliliters

Step-by-step explanation:

So if washing machine uses 5 times more than dishwasher

Dishwasher: 11 litters of each cycle

Washing machine: 11 x 5= 55 litters for each machine in litters

If 1 litter is equal to 1000 milliliter then 55 x 1000 = 55,000 milliliters

FORMULA for milliliter: multiply the volume value by 1000

What is the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths?

Answers

Given:

One midsegment of an equilateral triangle.

To find:

The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.

Solution:

All sides of an equilateral triangle are same.

Let a be the each side of the equilateral triangle.

Length of the midsegment is equal to the half of the non included side or third side.

[tex]Midsegment=\dfrac{a}{2}[/tex]

The sum of two side is

[tex]a+a=2a[/tex]

Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is

[tex]\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}[/tex]

[tex]\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}[/tex]

[tex]\text{Required ratio}=\dfrac{a}{4a}[/tex]

[tex]\text{Required ratio}=\dfrac{1}{4}[/tex]

[tex]\text{Required ratio}=1:4[/tex]

Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.

The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30

Where 27w represents the cost of w walks.


Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

There a few different ways to find a percentage, but in this case, I will change the fraction to be out of 100

20 × what = 100?

20 × 5 = 100

Multiply the denoninator by 5

6 / 20 × 5

What we do to the denominator, we must also do to the numerator

6 × 5 / 20 × 5

30/100

Percentages are out of 100, meaning if the fraction has the denominator "100," the numerator is the answer

Answer:

n>-5

Step-by-step explanation:

We have to distribute the -7 first, so:

-105<-7(5-2n) becomes:

-105<-35+14n

To find n, we have to add 35, so:

-105<-35+14n

+35   +35

We get 14n>-70. Now, we have to divide each side by 14 to find n.

14n/14>-70/14.

So, the solution becomes n>-5.

Jim needs to divide 769 coupon books equally among 9 stores. In which place is the first digit of the quotient? Select the word that makes the sentence true.

Answers

Answer:

tens

Step-by-step explanation:

The first thing we need to do is calculate the quotient. This would be the answer of dividing the number of coupons by the number of total stores.

769 / 9 = 85.4

If we count the first digit from the left as the first digit then that would mean 8 is the first digit and it is in the tens spot while the 5 is in the Ones spot.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (2, 720)(2,720).

Answers

Answer:

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Step-by-step explanation:

Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:

[tex]20 = a\cdot b^{0}[/tex] (1)

[tex]720 = a\cdot b^{2}[/tex] (2)

By dividing (2) by (1), we obtain the value for [tex]b[/tex]:

[tex]\frac{720}{20} = b^{2}[/tex]

[tex]b = \sqrt{\frac{720}{20} }[/tex]

[tex]b = 6[/tex]

And the value for [tex]a[/tex] is found by (1):

[tex]a = 20[/tex]

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].
