Answer 1

Answer:

The answer is

[tex]18\sqrt{3} [/tex]

If you need any explanation in it or anything on math you can communicate with me on Whats on this number +201557831028 or in email or face or anything

Step-by-step explanation:

This triangle is equilateral

Then

[tex]db = \frac{1}{2} ab = .5 \times 12 = 6 [/tex]

By using the phythgorth thearm you can find CD

[tex]cd = \sqrt{ {ab}^{2} - {db}^{2} } \\ = \sqrt{144 - 36} = 6 \sqrt{3} [/tex]

Then the eara of triangle is

[tex] \frac{1}{2} \times 6 \times 6 \sqrt{3} = 18 \sqrt{3} [/tex]

Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Which inequality represents the amount she can still spend this month and remain within her budget?
x greater-than 272
x less-than-or-equal-to 272
x less-than 272
x greater-than-or-equal-to 272

Answers

Answer:

1200-928 = 272 for the rest of the month Clarissa has to spend.

Step-by-step explanation:

So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over. Option 2 or B.

An ice cream factory makes 320 quarts of ice cream in 5 hours. How many quarts of ice cream could be made in 36 hours?

Answers

Answer:

2304 quarts

Step-by-step explanation:

An ice cream factory makes 320 quarts of ice cream in 5 hours. How many quarts of ice cream could be made in 36 hours?

From the above question

5 hours = 320 quarts

36 hours = x quarts

Cross Multiply

5 hours × x quarts = 320 quarts × 36 hours

x quarts = 320 quarts × 36 hours/5 hours

x quarts = 2304 quarts

Therefore, 2304 quarts of ice cream could be made in 36 hours.

Answers

Answer:

c = 74

d = 122

a = 58

b = 48

Step-by-step explanation:

C: a triangle always equals to 180, so 48 + 58 - 180 = 74

D: Angels next to each other on a line always equal to 180, so 180 - 58 = 122

A: Alternating interior angles of a parallel line equal to each other, so it would also be 58

B: A line is 180, so C + A - 180 = B, 74 + 58 - 180 = 48

True or False: If two parallel lines are cut by a transversal, each pair of supplementary angles are congruent

Kate wanted to sell a box of candy bars to raise money for her team. She sells 1/4 of the box at school. And 1/2 of the box to her neighbors. What fraction of the candy bars dose kate still have to sell. Put your answer in simplest form

Answers

Answer: 1/4

Step-by-step explanation:

Fraction of the box of candy bars sold at school = 1/4

Fraction of the box of candy bars sold to neighbor = 1/2

Therefore, the fraction that she has sold already will be:

= 1/4 + 1/2

= 1/4 + 2/4

= 3/4

The fraction of the candy bars that Kate still have to sell will be:

= 1 - 3/4

= 1/4

Kate has 1/4 candy bars left to sell

Julio bought a fish tank shaped like a rectangular prism. The inside of the tank measures 24 inches in length, 10 inches in width, and 12 inches in height. The tank is filled with water to a height of 8 inches. How many more cubic inches of water are needed to fill the tank to the top? Use paper to show your work.

Answers

Answer:

[tex]Volume = 960in^3[/tex]

Step-by-step explanation:

Given

Empty Tank

[tex]Length = 24in; Width=10in; Height = 12in[/tex]

When filled with water, the height is:

[tex]Height = 8in[/tex]

Required

Determine how many more cubic inches needed

First, we calculate the difference between the height of the tank and the height of the water.

[tex]H = 12in - 8in[/tex]

[tex]H = 4in[/tex]

The volume of water to full the tank is then calculated as:

[tex]Volume = Length * Width * H[/tex]

[tex]Volume = 24in * 10in * 4in[/tex]

[tex]Volume = 960in^3[/tex]
