Answers

Answer:

1.25

Step-by-step explanation:

First we should fill in what we know. They mentioned that the y would be the numerator (# on the top) and the x would be the denominator (# in the bottom).

[tex]\frac{3}{24} =\frac{y}{10}[/tex]         <----  This will be your proportion

Now we will cross multiply and make a equation. So we will do 3 * 10 which equals 30 and then 24 * y which is 24y. So now our equation will look like this.

[tex]30=24y\\y=1.25[/tex]

Then when you solve the equation you'll get 1.25

Answer:

Bagels are 4 and Muffins are 2

Step-by-step explanation:

solve the system of equations

Answer:

Bagels are 4 and the muffins are 2 or the first answer

Step-by-step explanation:

2b+m=10

3b+m=14

we can subtract the equations

-b=-4

multiply both sides by -1 to get

b=4 meaning a bagel is four dollars

we can then subsitute this

2(4)+m=10

8+m=10

subtract 8 from both sides

m=2

subsitute these into the second equation to check

3(4)+(2)=14

12+2=14

14=14

Therefore the answer is Bagels are 4 and the muffins are 2 or the first answer

Describe the graph of y = |x - 2| + 4

Answers

Answer:

Step-by-step explanation:

Note that this function resembles the absolute value function y = |x|.

The graph of y = |x| has its vertex at (0, 0) and opens up in a v-shape.

The graph of y = |x - 2| looks the same as that of y = |x|, but the entire graph has been translated 2 units to the right.

The graph of y = |x - 2| + 4 is that of y = |x - 2|, translated 4 units up.

8. Aaron and Zelly want to rent a tandem bike so that

they can ride together. The rental for a tandem bike is

$18.50 per hour plus $3 for each helmet. Aaron and

Zelly have $80 to spend on the bike rental. Which

equation can be used to find h, the number of hours

they can rent a tandem bike? (hint: if you do not know

what a tandem bike is, you need to look it up!)

80 = 6h + 18.50

80 = 18.50h + 3

80 = 18.50h + 6

80 = 3h + 18.50

Answers

Answer:

[tex]80 = 18.50h + 6[/tex]

Step-by-step explanation:

Given

[tex]Amount = \$80[/tex]

[tex]Rent = \$18.50[/tex] per hour

[tex]Helmet = \$3.0[/tex]

[tex]Individuals =2[/tex]

Required

Derive an expression for the scenario

A tandem bike allows 2 individuals to ride on it at a time.

So, they will only pay for one rental fee because both can ride on it at the same time.

However, they need to get separate helmets.

For Helmets, they will spend:

[tex]\$3 * 2 =\$ 6[/tex]

For Rental, they will spend

[tex]\$18.50 * h = \$18.50h[/tex] for h hours.

[tex]Total = Rentals + Helmets[/tex]

[tex]Total = 18.50h + 6[/tex]

Recall that they have just $80 to spend

So, substitute 80 for total

[tex]80 = 18.50h + 6[/tex]

Hence, option C answers the question.

You have 5814 meters of rope you need to cut into 27 sections how many 27 meters secton of rope will you be able to create and how much rope will be left over as waste

Answers

Answer:

215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left

Step-by-step explanation:

we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:

you have to divide 5,814 meters by 27 meters = 215.333

that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)
