Answer:B mark me brainliest

Step-by-step explanation:Recall that slope is rise over run

slope = rise/run

The rise being the change in y, while the run is the change in x.

So we could informally think of it as slope = y/x

-----------

Since we're told that it "has a rise of 2 and run of 3", this means slope = 2/3.

The slope is both y/x and also 2/3.

Equating the two expressions leads us to y/x = 2/3. This is why choice B is the final answer.

Ty is at Home Depot and must decide whether to buy paint in 10 individual quart cans or to buy it in both gallon and quart cans.

Ulleksa [173]

Find the cost of 4 quarts:

$ 6.99 [Cost of 1 quart] x 4 [Number of quarts] = $27.96 [Cost of 4 quarts]

Find the difference in price between 1 gallon and 4 quarts.

$ 27.96 [Cost of 4 quarts] - 20.99 [Cost of 1 gallon] = $ 6.97 [Difference]

One gallon of paint is less expensive than 4 quarts. The amount you save, $6.97, is just about the price of 1 quart of paint. When you buy the gallon, you get nearly 1 quart free.

Find out how many gallons to buy. Divide the total number of quarts needed by 4. This answer will tell Michael the number of gallons and quarts he needs.

10 ÷4 = 2 Gallons, 2 quarts

Two gallons and 2 quarts are equal to 10 quarts.

Find the cost.

$ 20.99 [Cost per gallon] x 2 = $41.98 [Cost of 2 gallons]

$ 6.99 [Cost per quart] x 2 = $13.98 [Cost of 2 quarts]

$ 41.98 [Cost of 2 gallons] + 1 3.98 [Cost of 2 quarts] = $ 55.96 [Total cost]

10 individual quarts cost $69.90 vs $55.96

So answer is C/2 gallons 2 quarts

The volume of a cylinder is 675π cm3. The radius of the base of the cylinder is 5 cm. What is the height of the cylinder?

frosja888 [35]

Answer: 27 cm

Step-by-step explanation:

We know that the volume of a cylinder is $V=\pi r^2h$ . Since we were given the volume and radius, we can plug them in and solve for height.

$675\pi =\pi (5^2)h$ [divide both sides by π]

$675 = (5^2)h$ [exponent]

$675=25h$ [divide both sides by 25]

$h=27$

Now, we know that the height is 27 cm.

Miguel’s savings account balance changed by -$48 over a year because a banking fee was withdrawn every month. He wants to find t

nekit [7.7K]

Answer:

-48 ÷ 12

Step-by-step explanation:

account balance changed over a year = -$48

In a year, there are 12 months. Above statement can also be written as

account balance changed in 12 months = -$48

we have to find monthly change, so we divide LHS and RHS by 12

account balance changed in 12 /12 months = -$48/12

Thus, account balance changed in 1 months = -$48/12

which is represented option 4 i.e -48 ÷ 12
