Can somebody explain what the problem is explaining to me

Mathematics
1 answer:
Olin [163]2 years ago
4 0

Answer:

The problem basically is saying that find two numbers that add up to 8, where one is three times the other.

Step-by-step explanation:

The best thing to do here is to write a simple system of equations.

b+y=8

b=3y

The first equation means that the total blue paint plus the total yellow paint is equal to 8 ounces.

The second equation means that the blue paint is equal to 3 times the yellow paint.

We can isolate b in the first equation to get b=-y+8

-y+8=3y

8=4y

y=2.

So we have that she needs two ounces of yellow paint.

Therefore she needs six ounces of blue paint.

Drag the yellow bar to 2, and the blue bar to 6.

Hope this helps!

An aquarium is leaking water at the rate of three quarts in 4 days.How many quarts are leaked in 1 week?How many days does it ta
Simora [160]

Answer:

\frac{21}{4} quarts

12 days

Step-by-step explanation:

Given that:

Amount of water leaked in 4 days = 3 quarts

To find:

Number of quarts leaked in 1 week?

Number of days taken for the leakage of 9 quarts of water?

Solution:

We can simply use unitary method or the ratio to find the answers of the questions asked in the statement.

As per question statement:

Amount of water leaked in 4 days = 3 quarts

Dividing by 4 on both sides:

Amount of water leaked in 1 day = \frac{3}{4} quarts

Multiplying by 7 on both sides:

Amount of water leaked in 7 days = \frac{3}{4}\times 7 = \frac{21}{4} quarts

Number of days taken for the leakage of 3 quarts = 4 days

Multiplying by 3 on both sides:

Number of days taken for the leakage of 3 \times 3 = 9 quarts = 4 \times 3 = <em>12 days</em>

alukav5142 [94]

Answer:

314 square feet

Step-by-step explanation:

we know that

The area that will be covered by the spray of the quarter-circle sprinkler head, is equal to the area of a quarter circle with radius of 20 feet

so

The area of a quarter circle is

A=\frac{1}{4}\pi r^{2}

we have

r=20\ ft

\pi =3.14

substitute

A=\frac{1}{4}(3.14)(20)^{2}=314\ ft^2
