How many quarts are in 40 gallons

Dafna11 [192]

To find out how many quarts there are in 40 gallons, we simply need to know how many quarts there are in one gallon. As the name implies, there are 4 quarts in one gallon, so we simply need to multiply 4 * 40 to find the amount of quarts in 40 gallons.

4 * 40 = 160

There are 160 quarts in 40 gallons.
Hope that helped! =)

Brenda and her best friend went on a vacation together. They both paid for a flight, and Brenda had a fancy room for $150 per ni

Mila [183]

Answer:

A. 2x + 150y = 1,500

2x + 120y = 1,320

The flights were $300 each, and they stayed 6 nights.

B. $1,380

Step-by-step explanation:

Let x be the cost of the flight (in one side) and y be the number of nights on their vacation.

A. Brenda had a fancy room for $150 per night, then she paid $150y for y nights. Brenda's total is $1,500, then

$150y+2x=1,500$

Brenda's friend had a smaller room for $120 per night, then she paid $120y for y nights. Brenda's friend total is $1,320, then

$120y+2x=1,320$

Subtract two equations:

$150y+2x-120y-2x=1,500-1,320\\ \\30y=180\\ \\y=6$

Substitute into the first equation:

$150\cdot 6+2x=1,500\\ \\900+2x=1,500\\ \\2x=600\\ \\x=300$

Hence

2x + 150y = 1,500

2x + 120y = 1,320

The flights were $300 each, and they stayed 6 nights.

B. If a third friend joined them and stayed in a mid-range room for $130 per night, then he paid $\$130\cdot 6=\$780$

The total cost is

$\$780+\$600=\$1,380$

Jackie wants to plant 2 1/2 rows of corn in her garden. She needs 3 1/4 ounces of seed for each row. How many totally ounces of

dimaraw [331]

Answer:

$8\frac{1}{8}$ ounces.

Step-by-step explanation:

Given

Number of rows of corn $=2\frac{1}{2}$ rows.

Seed required in each row is $=3\frac{1}{4}$ ounces.

So, total seed required to plant corn in $2\frac{1}{2}$ rows is

Number of rows of corn $\times$ Seed required in each row

$=(2\frac{1}{2})\times(3\frac{1}{4})\\\\\ Multply\ denominator\ to\ whole\ number\ part\ then\ add\ that\ number\ to\ numerator\\\\=\frac{5}{2}\times\frac{13}{4}\\ \\Divide\ 65\ by\ 8\ we\ have\ 8\ with\ reminder\ 1\\\\=\frac{65}{8}\\\\So,\frac{65}{8} =8\frac{1}{8}$
