Step-by-step explanation:
f=5x-2y
when X=3 & y= -2
or, f=5×3 - 2×(-2)

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?
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?
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.

At Jayla's Swimwear, 6 out of the 20 styles at the store are bikinis. What percentage of swimsuit styles at the store are bikinis?

Step-by-step explanation:
Make a fraction
6/20
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
30%

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.
1. What is a light year? The distance between the Earth and the Sun is 150 x 10^6 km. Express this distance in light years
Answer:
A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.

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.
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).
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].
