-988

Step-by-step explanation:

see all u do is subtract 2-5 multiply 5 times 3 and 3 times 22 and 22 times 33 and end up getting -988

Now, divide each by three ⇣

9 / 3 = 3

C: after 5 seconds

Answer:

-2

Step-by-step explanation:

To find the slope, you can do rise (change in y)/run (change in x). Take the points (0, 0) and (3, -6) There is a change of -6 in the y-direction (you can count on the graph) and a change of +3 in the x-direction. Using this, rise/over run, plug in -6/3 to get -2 as the slope.

21.00 hours

Step-by-step explanation:

4 hours, 30 minutes=4.5 hours

4 hours, 45 minutes=4.75 hours

5 hours, 30 minutes=5.5 hours

6 hours, 15 minutes=6.25 hours

4.5 + 4.75 + 5.5 + 6.25 = 21.00 hours

The answer to your question is 4x²(x+2)(4x²-3x+3)

Answer:

Areas and volumes of cylinders etc

Step-by-step explanation:

Given:

h = 10.7 in

V = 619 in^3

Volume (V) = π[tex]r^{2}[/tex]h

619 = 22/7×[tex]r^{2}[/tex]×10.7

∴[tex]r^{2}[/tex] = 619x7/ 22x10.7

r = 4,3 in approx.

Answer: 8

Step-by-step explanation:

We have to complete the operation in the parenthesis first. 8-2 is 6. Now we have to take 4(6) which is 24. Now we have 6^2-24. 6^2 is 36. So 36-24 is 12. 16-12 is 4. Now 2 times 4 is 8.

Answer:

a. [tex]1\frac{1}{8} in.[/tex]

Step-by-step explanation:

hey there,

< There are 8 marks between 1 in. and 2 in. and here we can see that the distance of the line goes only up to the first mark.

Imagine this like a pizza that's divided into 8, but you only took 1 slice. That means you took only [tex]\frac{1}{8}[/tex] of the pizza. It is the same here on the ruler.

It's not only 1/8 though because we also have to add in the first inch. After that inch, we also have 1/8 of an inch. So [tex]1\frac{1}{8}[/tex] in. would be your final answer. >

Answer:

Anthony mother's has enough flour for each of Anthony's friends to get a cupcake.

Step-by-step explanation:

Let suppose that Anthony and his friend will receive at least one cupcake, which means that Anthony's mother should make at least 9 cupcakes ([tex]\frac{3}{4}[/tex] dozens).

From statement we notice that quantity of cupcakes is directly proportional to the quantity of flour.

According to the recipe, the required amount of flour and cupcakes are, respectively:

Flour

[tex]3\,\frac{1}{3}\,cups = 3 \,cups +\frac{1}{3}\,cups = \frac{10}{3}\,cups[/tex]

Cupcakes

[tex]2\,\frac{1}{2}\,dozens = 2\,dozens +\frac{1}{2}\,dozens = \frac{5}{2}\,dozens[/tex]

If Anthony's mother has 1 cup of flour at her disposal, the amount of cupcakes is obtained by simple rule of three:

[tex]x = \frac{5}{2}\,dozen\times\frac{1\,cup}{\frac{10}{3}\,cups }[/tex]

[tex]x = \frac{3}{4}\,dozen[/tex]

In a nutshell, Anthony mother's has enough flour for each of Anthony's friends to get a cupcake.

Answer:

$2248.33

Step-by-step explanation:

Salary = $71,000/yr

so salary per month:

12 --> months in a year

[tex] \frac{71000}{12} = 5916.67[/tex]

if the one time agency fee is 38% of monthly salary'

($5916.67) (0.38) = $2248.33

Answer:

This is a clear case to use the Pythagorean Teorem, as we need to calculate diagonal lenght of a rectangle, and to do so, we can divide it in right triangles.

As the Pythagorean Teorem says [tex]a^2 + b^2 = c^2[/tex]

We can now replace on [tex]a^2 + b^2 = c^2[/tex] the numbers we have [tex]24^2 + 32^2 = c^2[/tex]

Now, we solve [tex]24^2 + 32^2 = c^2[/tex] by operating:

[tex]\sqrt{1600} = b[/tex]; b = 40

The diagonal lenght is 40 inches r
