Step-by-step explanation:

1/3×,22/7×4.5×4.5××7.25

=153.66cm3

Answer:

The missing height is approximately 78.8011 feet.

Step-by-step explanation:

To solve for the height of the kite, you need to use a trigonometry function called sine. Sine - or sin when used to calculate - is most commonly used for right triangles, and the sine of a right triangle angle is equivalent to the side opposite (or the only side of the right triangle that does not help create that angle) of the angle divided by the hypotenuse of the right triangle. So you can now create the following function to solve the height: sin(52°) = [tex]\frac{x}{100}[/tex] where x represents the unknown height of the kite. From there, you can get that [tex]x = 100*sin([/tex]52°[tex])[/tex], which equals approximately 78.8011 feet. Since there isn't a specific decimal place to round to, I rounded the answer to four decimals. If your teacher asks you to round to a specific place value, use 78.8011 to get your simplified answer.

Answer:

U= ka +ba=a (Given)

Step-by-step explanation:

U=ka + baa= Ukinana HAHAHA

Answer:

[tex]a = \frac{u}{k + b} [/tex]

Step-by-step explanation:

Factor out the common term a.

[tex]u = a(k + b)[/tex]

Divide both sides by k + b.

[tex] \frac{u}{k + b} = a[/tex]

Switch sides.

[tex]a = \frac{u}{k + b} [/tex]

hence, the answer is u/k + b.

Answer:

7x+4/3x+2= -4/3 don't know

Answer:

50m²

Explanation:

first, we have to find the length and width of the backyard. since 4cm represents 5m, we know that the real width of the backyard is 5m.

as for the length of the backyard, 8cm is double of 4cm so we can also double 5m to get 10m.

now, we can find the area by taking 5m × 10m = 50m².

$11,000

Step-by-step explanation:

Because,

Answer:

11000

Step-by-step explanation:

Answer:

We have the system:

y > x^2 - 1

y < (-1/2)*x + 3

To find the solutions of this set we need to graph the solutions range of both sets, and see the intersection between these solution ranges.

How we do it?

Start with the first one.

First, we graph the equation:

y = x^2 - 1

Now because we are using the symbol ">" means that y is smaller than the thing at the right, then the graph of the equation will be with a dashed line (which means that the points on the line are not solutions) and we will shade all the region above the line

For the other inequality we do the same:

First we graph:

y = (-1/2)*x + 3

And because we have the symbol "<" we again use a dashed line, but this time we will shade all the region below the line.

Once we shaded both regions, the region where we have both shades will be the region of solutions for the system of inequalities.

You can see the graph below.

Answer:

1 quart = .947 L

3 Q = 2.841 L

So you should use 2.841 L to dissolve the powder

One quartz is equal to 32 oz, then 2.88 liters of water are used to dilute the powder.

The unit conversion deals with the operation to change one form of the unit to another form of unit.

Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters.

We know that

1 quartz = 32 oz

3 quartz = 96 oz

Since 30 milliliters per oz

Then

30 milliliters × 96 oz = 2880 milliliters

Since 1000 milliliters per liter, then we have

[tex]\rm \dfrac{2880}{1000}=2.88\ liters[/tex]

2.88 liters are used to dilute the powder.

Answer:

F) 63

Step-by-step explanation:

Find the original total stories 10 + 8 + 16 + 8 = 42.

Original ratio of Mary's stories to total stories is 8/42 or 4/21.

Then form equation 4/21 = 12/x ; multiply both sides of 4/21 by 3.

4/21 = 12/63

The students need to write 63 stories to keep the ratio of Mary's stories to total stories the same.

Answer:

Expression is 3x² + 5x - 17

Step-by-step explanation:

We are told the number of lights produced by a company is;

Number of lights = 15x^3 + 16x^2 – 100x + 51

Also, number of companies that purchased the light bulbs is 5x - 3.

Thus;

The average number of bulbs purchased per company = (15x^3 + 16x^2 – 100x + 51)/(5x - 3)

I have attached the calculation using long division method to get;

3x² + 5x - 17

Answer:

The  formula for the area of a parallelogram is base x height.

base x height = area

So, I will form an equation.  b (base)  x 3 ft (height) = 18 1/3

Next divide 3 from 18 1/3, so 18 1/3 divided by 3. This equals1 6 1/9

To check: 6 1/9 x 3 = 18.3333333333 or 18 1/3

13*6=78

Step-by-step explanation:

If one part of something is equal to 13, then 6 parts are equal to 13*6. Let us denote that "something" by x, and we get

[tex]x = 6 \times \frac{1}{6} x = 6 \times 13[/tex]

Answer:

225 students

Step-by-step explanation:

Total number of students = 900 students

percent that bring lunch to school everyday = 25%

Number of student that bring lunch to school = 25% of 900

Number of student that bring lunch to school = 0.25 * 900

Number of student that bring lunch to school = 225
