good luck if this helped

Answer:

144

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

This is a right angle (complementary angles) so 90-43 is 47 and the angel is x - 7 so you have to add 7. Answer is 54 <3

Answer:

2025+18=2043

Step-by-step explanation:

Answer:

118

Step-by-step explanation:

4x^2 + 3y

4(5^2) + 3(6)

4 * 25 + 18

100 + 18

118

Answer:

B is the correct answer

Step-by-step explanation:

Since it gets rid of the y so you could find the x and then work around to find the Y.

Answer:

Multiply the first equation by 3.

Step-by-step explanation:

Answer:

The inside angles have to equal 180 degrees so

So Hazel is correct

Answer:

2

Step-by-step explanation:

consider the two points. Gradient=change in y/change in x. So 4/2=2

Answer:

-3

Step-by-step explanation:

Answer:

9π cm³

Step-by-step explanation:

We require to find the height (h) of the cylinders

The volume (V) is calculated as

Ah ( A is the base area and h the height ), then

3πh = 18π ( divide both sides by 3π )

= 6

Then the height of the smaller cylinder = 6 - 3 = 3 cm

3π × 3 = 9π cm³ ← volume of smaller can

Step-by-step explanation:

Answer:

If it is using base and height: A = b x h

If using Trigonometry:  A = b2 x Sin(a)

Step-by-step explanation:

A = Area

B= Base

H= Height

Answer:

A.

have a good day :)

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Ed's answer is correct but I would have just multiplied each side by the reciprocal of 2/3 which is 3/2, which will isolate 'm'

m = 1/4 x 3/2

m = 3/8

Answer:

t = 4

Step-by-step explanation:

In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.

-6t = -24

÷-6    ÷-6

t = 4

When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

Answer:

D

Step-by-step explanation:

The inverse property states that any number multiplied by its reciprocal equals 1.

Answer:

15 tables

Step-by-step explanation:

75/5 = 15

Answer:

There are 15 tables in the library.

Step-by-step explanation:

You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.

Step-by-step explanation:

Answer:

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Step-by-step explanation:

Given

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

[tex]h(x) = -2(2x^2 - 8)[/tex]

[tex]h(x) = -4(x^2 - 4)[/tex]

[tex]h(x) = -4x^2 + 16[/tex]

Required

Which shows the zeros of h(x)

To determine the zeros of a function, the function must be written as:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

Where

[tex]n \ne 0[/tex]

[tex]\± a,\± b[/tex] are the zeros

Of options (a) to (d), only (a) is written in the form:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

i.e.

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Other options do not show the zeros

Answer:

C. 10 - 2 = 8

Step-by-step explanation:

[tex] = (Q _{3} - Q _{1}) \\ = ( \frac{3}{4} \times 7) - ( \frac{1}{4} \times 7) \\ = (6 {}^{th} - {2}^{nd} ) \\ = (10 - 2) \\ = 6[/tex]

Complete Question

Carmen is putting together a business plan for her sandwich restaurant, Subs Away, so she can expand to another location. She wants to include some information about recent sales but only has certain information about last month's sales. She currently offers ham, turkey and vegetarian sandwiches. She sells the ham sandwiches for $10 each and the turkey sandwiches for $11.25.

Last Month's Vegetarian Sales

Total Sandwiches Sold 75

Total Income $712.50

How much does Carmen charge for the vegetarian sandwich?

Answer:

 [tex]X=9.5[/tex]

Step-by-step explanation:

From the question we are told that:

Total Vegetarian Sandwiches Sold [tex]T_{vs}=75[/tex]

Total Vegetarian Sandwiches Income [tex]T_{vi}=$712.50[/tex]

Generally the equation for Cost of vegetarian sandwich is mathematically given by

 [tex]X=\frac{Total\ income\ from\ vegetarian\ sandwich}{No.\ of\ vegetarian\ sandwich\ sold}[/tex]

 [tex]X=\frac{T_{vi}}{T_{vs}}[/tex]

 [tex]X=\frac{712.50}{75}[/tex]

 [tex]X=\$9.5[/tex]

You do know you have to give us the answer choices right till then can’t help sorry

Answer:

20 inches

Step-by-step explanation:

Step 1: Subtract the total from what was left

[tex]95 - 15 = 80[/tex]

Step 2: Divide the result into the 4 pieces

[tex]80 \div 4[/tex]

[tex]=\frac{80}{4}[/tex]

[tex]= 20[/tex]

Each of the four pieces Lily cut was 20 inches.

Answer:

[tex](fog)(x)=|x+2|[/tex]

[tex]Dom_{fog} = R[/tex]

[tex]Range_{fog}=[0,\infty)[/tex]

Step-by-step explanation:

Answer:

They need to make at least 12 batches.

Step-by-step explanation:

First, we need to find how many cookies in total, so we multiply 70 by 4.

70*4 = 280.

Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.

Time to check:

12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.

Hope this helps.
