Step-by-step explanation:

Answer:

Company A = $13

Company B = $12.73

Company B

Step-by-step explanation:

To determine the unit cost for each company, divide the price of chocolate by the number of pounds

Unit cost = price ÷ total pounds offered

Company A

$32.50 ÷ 2 1/2

$32.50 ÷ 5/2

$32.50 x 2/5  = $13

Company B

$35 ÷ 2 3/4

$35 ÷ 11/4

$35 X 4/11 = $12.73

$12.73 is less than $13. Company b has a lower price per pound

Answer:

The answer is choice A that is "Area".

Step-by-step explanation:

According to the area of the square [tex](A)= side^2[/tex]  

Given side =7

So, the area= [tex]7^2= 7 \times 7=49[/tex]  

Hey there!

The correct answer is 50 degrees.

To do this, we can figure out all the angles in the triangle. We know one angle: 45 degrees. To find the angle above that angle, we can use the 95 degrees and use linear angles to figure out that missing angle.

A linear pair adds up to 180 degrees, which means that 95 + (missing angle) = 180. 95 + 85 = 180. Therefore, we have two of the three angles in the triangle.

In a triangle, the number of angles adds up to 180 degrees, which means that 45 + 85 + (angle across from x) = 180. 45 + 85 + 50 = 180.

Now we have all the angles in the triangle.

With that information, we can use vertical angles to solve for x. If there are two lines that intersect, the angles opposite eachother are always equal. The angle opposite of x is 50; therefore x is equal to 50 degrees.

Have a terrificly amazing day! :D

The answer is C i think.

Answer:

3 is the unit rate

Step-by-step explanation:

15/3 is 3 which is your individual value per row.

Answer:

C, 0.15

0.15 is 15/100, which is 15 percent.

multiply 500 times 0.15 gives you 15 percent of 500.

Answer:

9(x^6)(y^3)

Step-by-step explanation:

The volume = LBH = x²y

.°. If a pyramid and a prism have the same base and height, their volumes are always in the ratio of 1/3xVolume of prism.

The volume of Pyramid = 1/3*x²y

h = 3 *1/3x²y/x²

h = 3*1/3x²y*1/x²

h = 3*1/3y

Answer:

40

Step-by-step explanation:

The answer should be 40 assuming that there are positive real numbers.

You simplify the radical into a product with known factors

sorry If that doesnt make sense lol

Answer:

2.9195

Step-by-step explanation:

To find the time we need to equate the function the zero and solve for t:

[tex] { - 16t}^{2} + 45t + 5 = 0[/tex]

Using the general formula we have that:

[tex]t = \frac{ - 45 + \sqrt{ {45}^{2} - 4 ( - 16)(5)} }{2( - 16)} \\ = \frac{ - 45 + \sqrt{2345} }{ - 32} [/tex]

then:

[tex]t = \frac{ - 45 + \sqrt{2345 } }{ - 32} = - 0.107 \\ or \\ t = \frac{ - 45 - \sqrt{2345} }{ - 32} = 2.9195[/tex]

Since the time has to be positive we conclude that the ball is in the air 2.9195 seconds.

Answer:

x=17°

Step-by-step explanation:

Answer:

£364.42

Step-by-step explanation:

£355.68 ÷ 38 hours = £9.36 per hour

£9.36 + £0.23 = £9.59 per hour

£9.59 * 38 = £364.42

Answer: $20.59

Step-by-step explanation:

0.13 * 6 = 0.78

25 - 0.78 = 24.22

85% * 24.22 = 20.59

Answer:

1-21m hight and 23 lenght

2-45 hight and 11 length

Answer:

5 days

Step-by-step explanation:

Given

Damian

[tex]Base\ Items = 5[/tex]

[tex]Rate = 3[/tex] daily

Andrea

[tex]Rate =4[/tex] daily

Required [Missing from the question]

How long will they get the same number of items

Represent the number of items with x and the days with y.

So:

For Damian

[tex]y = Base\ Items + Rate * x[/tex]

[tex]y = 5 + 3 * x[/tex]

[tex]y = 5 + 3 x[/tex]

For Andrea

[tex]y = Rate * x[/tex]

[tex]y = 4* x[/tex]

[tex]y = 4x[/tex]

Equate both expressions.

[tex]4x = 5 + 3x[/tex]

Collect like terms

[tex]4x - 3x = 5[/tex]

[tex]x = 5[/tex]

Hence, they will have equal amount of items after 5 days
