Jacob mixes ⅓ cup of yellow paint for every ⅕ cup of blue paint to make green paint. How many cups of yellow paint are needed fo

Nana76 [90]

Answer:

$\frac{5}{3}$ cups

Step-by-step explanation:

Jacob mixes $\frac{1}{3}$ cup of yellow paint for every $\frac{1}{5}$ cup of blue paint to make green paint.

The ratio of yellow paint to blue paint = $\frac{1}{3} : \frac{1}{5}$

= 5:3

$\frac{1}{5}$ cup of blue paint = $\frac{1}{3}$ cup of yellow paint

1 cup of blue paint = $\frac{1}{3}$ ÷ $\frac{1}{5}$ cup of yellow paint

⇒ $\frac{1}{3}$ ÷ $\frac{1}{5}$

⇒ $\frac{5}{3}$

Hence, For 1 cup of blue paint needed $\frac{5}{3}$ cups of yellow paint.

kirill [66]

Answer:

$\frac{1}{5}$ fraction of gallon is in each bottle.

Step-by-step explanation:

As per the given condition: G.O is going on a hike in the mountains on a hot summer day he has 4/5 gallon of water that he split into 4 bottles.

⇒ in 4 bottle he has $\frac{4}{5}$ gallon of water.

Unit rates defined as when are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, then they are called unit rates.

By unit rate definition,

In 1 bottle he has = $\frac{4}{5} \times \frac{1}{4} = \frac{1}{5}$ gallon of water.

therefore, the gallon in each bottle in fraction is, $\frac{1}{5}$

What is the first step in solving the quadratic equation x2 = StartFraction 9 Over 16 EndFraction? Take the square root of both

balu736 [363]

Answer:

The first step is

Take the square root of both sides of the equation

Step-by-step explanation:

we have

$x^{2} =\frac{9}{16}$

Solve for x

step 1

Take square root both sides

$x=(+/-)\frac{3}{4}$

the solutions are

$x=+\frac{3}{4}$ and $x=-\frac{3}{4}$

therefore

The first step is

Take the square root of both sides of the equation

From 1980 to 1990, the consumer price index (CPI) increased from 82.4 to 130.7. If a gallon of apple juice cost $0.95 in 1980 an

ryzh [129]

Answer: C $1.51

To solve this, start with a proportion. Put the CPI numbers on the left and the apple juice prices on the right.

You will have:

82.4/130.7 = 0.95/x

Cross multiply to solve and you will get the price of the juice is $1.51.

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select t

Pepsi [2]

Answer:

Step-by-step explanation:

Two lines are perpendicular if the first line has a slope of $m$ and the second line has a slope of $\frac{1}{-m}$ .

With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:

$5x - 2y = -6$

$-2y = -5x - 6$

$y = \frac{5}{2}x + 3$

We now know that $m = \frac{5}{2}$ for the first line, which means that the slope of the second line is $m = \frac{-2}{5}$ . With this, we have the following equation for our new line:
