For every 4 gallons of green paint he uses 3 gallons of blue paint. Drag the correct number of each type of paint into the box t

Inga [223]

Answer:

Amount of green color used =

$\dfrac{64}{7}\text{ gallons}$

Step-by-step explanation:

We are given the following in the question:

Every 4 gallons of green paint is mixed with 3 gallons of blue paint. to make a particular shade.

Ratio of green color to blue paint can be calculated as:

$=\dfrac{\text{Amount of green color}}{\text{Amount of blue color}}\\\\=\dfrac{4}{3}$

Amount of shade = 16

Amount of green paint = $4x$

Amount of blue paint = $3x$

Thus, we can write:

$4x + 3x = 16\\7x = 16\\\\x = \dfrac{16}{7}$

Amount of green color used =

$4x = 4\times \dfrac{16}{7} = \dfrac{64}{7}\text{ gallons}$

Amount of blue paint used =

$3x = 3\times \dfrac{16}{7} = \dfrac{48}{7}\text{ gallons}$

A dealer sold 200 tennis racquets. Some were sold for $33 each, and the rest were sold on sale for $18. The total receipts form

Mumz [18]

120 tennis racquets were sold for $ 18 each

Solution:

Let x = number that sell for $18 each

Then, 200 - x = number that sell for $33 each

The total receipts form these sales were 4800 dollars

Thus we frame a equation as:

number that sell for $18 each x 18 + number that sell for $33 each x 33 = 4800

$x \times 18 + (200-x) \times 33 = 4800\\\\Solve\ the\ above\ equation\ for\ x\\\\18x + 6600 - 33x = 4800\\\\Move\ the\ variables\ to\ one\ side\\\\18x-33x = 4800-6600\\\\-15x = -1800\\\\Divide\ both\ sides\ of\ equation\ by\ -15\\\\x = 120$

Thus 120 tennis racquets were sold for $ 18 each

dezoksy [38]

Answer:

Major $X_i$ %

_________________________________________

Accounting 240 (240/800)*100=30%

Finance 160 (160/800)*100=20%

Management 320 (320/800)*100=40%

Marketing 80 (80/800)*100= 10%

_________________________________________

Total 800 100%

Step-by-step explanation:

For this case we can create the following table calculating the percent frequency as:

$\% = \frac{X_i}{n}$

Where $X_i$ represent the number of students for the i category and n the total sample size.

Major $X_i$ %

_________________________________________

Accounting 240 (240/800)*100=30%

Finance 160 (160/800)*100=20%

Management 320 (320/800)*100=40%

Marketing 80 (80/800)*100= 10%

Consider the rectangle enlargement. Pls answer the three questions I will mark brainliest!!

Alenkasestr [34]

Answer:

Perimeter of the original Rectangle is

2(4.5+4.3)=2×8.8= 17.6 mm

Side length of the enlarged rectangle is

$\frac{4.5}{4.3} = \frac{24.3}{x} \\ x = \frac{24.3 \times 4.3}{4.5} \\ \boxed{x = 23.22 \: mm}$

Perimeter of the enlarged rectangle

2(24.3+23.22)= 2×47.52= 95.04 mm
