Jorge has a swimming pool that is rectangular in shape. The length and width of the pool are 24 feet and 14 feet. He also knows that the pool has a consistent depth of 5 feet. He needs to add 4 drops of chlorine for every 50 cubic feet in his pool. How many drops of chlorine should Jorge use to chlorinate his pool properly?

Answers

Answer:

140 drops

Step-by-step explanation:

Length of the pool = 24 feet

Width of the pool = 14 feet

Depth of the pool = 5 feet

Volume of the pool = length × width × depth

= 24 ft * 14 ft * 5 ft

= 1,750 ft³

Volume of the pool = 1,750 ft³

He needs to add 4 drops of chlorine for every 50 cubic feet in his pool.

Number of 50 cubic feet in the volume of the pool = Volume of the pool / 50 ft³

= 1,750 ft³ / 50 ft³

= 35

Number of 50 cubic feet in the volume of the pool = 35

How many drops of chlorine should Jorge use to chlorinate his pool properly?

Number of drops of chlorine Jorge should use = number of drops per 50 ft³ × Number of 50 cubic feet in the volume of the pool

= 4 × 35

= 140 drops

Number of drops of chlorine Jorge should use = 140 drops

Answer:

70°

Step-by-step explanation:

In the context it says that Franklin St. is parallel to Washington St.

The 110° formed by Franklin St. and Mulberry St. is a supplementary angle to Angle x.

Supplementary angles are angles that add up to each other to make 180°

So lets subtract:

180 - 110 = 70°

Angle x = 70°

Answer:

23.25 m^3

Step-by-step explanation:

First you must find the area of the base you find it like this:

A(area)=1/2(one half)3.1(base)2.5(height)

you get 3.875(this is the area of the base)

now you have to multiply the area of base times the area of height like this:

A(area)=3.875(area of base)6(height)=23.25

so the answer is 23.25m^3

Hope I'm right have a great day!

find two numbers if their sum is 3/5 and their difference is 7 1/5

Answers

Answer:

A = 3 + 9/10

B = -(3 + 3/10)

Step-by-step explanation:

We have two numbers, A and B, such that:

A + B = 3/5

A - B = 7 + 1/5

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:

A = 3/5 - B

Now we can replace this in the other equation:

A - B = 7 + 1/5

(3/5 - B) - B = 7 + 1/5

3/5 - 2*B = 7 + 1/5

-2*B = 7 + 1/5 - 3/5

-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5

B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)

Now that we know the value of B, we can use the equation

A = 3/5 - B

To find the value of A:

A = 3/5 - ( -(3 + 3/10))

A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10

The numbers are:

A = 3 + 9/10

B = -(3 + 3/10)

In triangle ABC, if angle A measures 78° and angle B measures 63º, what is the measure of angle C?

Answers

Answer:

∠C=39°

Step-by-step explanation:

The interior angles of a triangle will always have a sum of 180°.

∠A+∠B+∠C=180°

78°+63°+∠C=180°

∠C=180°-78°-63°

∠C=39°

Answer:

39 degrees

Step-by-step explanation:

All triangles will add up to 180 degrees. So, you know that angle C added with angles A and B will equal 180. if you take 180, minus 78, minus 63, you get the answer 39.

If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.

Common Error:

A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.

Read the text from the following website: www.growingnation.orgA Growing NationAfter the American Revolution, the newly formed United States realized that it lacked room to grow. The states created in the Declaration of Independence in 1776 were limited in size. As the population increased, more people were competing for the same amount of land. Consequently, land became more expensive, and overcrowding became an issue. The thirteen states were bordered by the Atlantic Ocean and the territories of other nations. If the United States was going to have a future, it needed to increase its territory.President Thomas Jefferson believed that for Americans to be virtuous and free, they needed to farm land. He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States.The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict. The United States purchased Florida from Spain with the Florida Purchase Treaty of 1821. Instead of paying Spain a set amount, the United States would pay the $5 million Americans claimed were owed to them by Spain. After Texas declared independence from Mexico, it was annexed by the United States and became an official state in 1845. Another land controversy occurred between Great Britain and the United States, as both countries claimed the Oregon region. The dispute was settled in the 1846 Oregon Treaty, which separated the countries by the line of the 49th parallel. Mexico refused to let the United States buy California and New Mexico, so the two countries eventually went to war. Because the Americans won the war, the United States was able to buy lands in the Southwest in 1848. The United States paid Mexico $10 million for an area of land in the Southwest in the 1853 Gadsden Purchase, stretching its borders from sea to sea.According to information in the text feature, in what year did the United States officially obtain land with access to the Pacific Ocean?1845184818211846 The cation that has the same number of electrons (isoelectronic) as Ne isNone of the listed optionsO NaMg 2-All of the listed optionsO AI 3- 24.
