Answer:

Q = P - n(x/100)

Step-by-step explanation:

P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.

So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;

Q = P - n(x/100)

Step-by-step explanation:

I think that the answer is (3x + 4)

(x + 2)

The required range of the function g(x) = a|x| + b is y ≥ 0.

Let's analyze the function g(x) = a|x| + b step by step to determine its range.

The function |x| represents the absolute value of x, which means it always yields non-negative values. Therefore, a|x| will also be non-negative for any value of x.

Adding b to a non-negative value will shift the entire range up by b units, but it will still be non-negative.

Since a < 0, a|x| will be negative when x is positive. However, the absolute value function ensures that it will be positive when x is negative, balancing out the effect.

Finally, adding the constant term b to a|x| makes the entire range of g(x) non-negative.

In summary, the range of g(x) = a|x| + b is y ≥ 0.

Answer:

- 978.6 gallons per hour

Step-by-step explanation:

Given that :

Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal

Time during which change occurred : 2:00 pm to 4:00 pm

Average change per hour : [Change in gallon of gasoline / time interval (hour)]

Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons

Time interval = 4:00 pm - 2:00 pm = 2 hours

Hence, Average change per hour :

-1957.2 / 2

= - 978.6 gallons per hour

just looked up "what percentage is 12 out of 15 and it gave me an answer"

just do this for all ur other questions like this

Answer:

1. V≈1244.07

2. V≈54286.72

3.V≈23816.41

4. V≈254.47

5. V≈4247.43

6. V≈21714.69

7. V≈4712.39

Step-by-step explanation:

use the formula V=πr^2h

The volume of the given cylinders is 1. V≈1244.07 2. V≈54286.72 3. V≈23816.41 4. V≈254.47 5. V≈4247.43 6. V≈21714.69 7. V≈4712.39.

The volume of the cylinder is the product of the height, pie, and square of the radius.

The volume of the cylinder = [tex]\pi r^{2} h[/tex]

A.

a) The height of the cylinder is given as 11 in and the radius is 6 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 6^2 x 11

                                                    = 1244.07cubics in

b)  The height of the cylinder is given as 30 in and the radius is 24 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 24^2 x 30

                                                    = 54286.72 cubics in

c) The height of the cylinder is given as 21 in.

The radius of the base of the cylinder is given as 19 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 19^2 x 21

                                                    = 23816.41 cubics in

B.

d) The height of the cylinder is 9ft the radius is 3 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 3^2 x 9

                                                    = 254.47 cubics ft

e) The height of the cylinder is 8 ft the radius is 13 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 13^2 x 8

                                                    = 4247.43 cubics ft

f) The height of the cylinder is 27 ft the radius is 16 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 16^2 x 27

                                                    = 21714.69 cubics ft

g) The height of the cylinder is 15 ft the radius is 10 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 10^2 x 15

                                                    = 4712.39 cubics ft

Answer:

x = 48°

Step-by-step explanation:

In the given triangle XYZ,

Sides XY and XZ are congruent.

Therefore, both the sides will be equal in measure.

By the definition of isosceles triangle,

"Opposite angles of the equal sides are equal in measure"

m∠Y = m∠Z = x°

m∠X = 84° [Given]

By the triangle sum theorem,

m∠X + m∠Y + m∠Z = 180°

84° + x° + x° = 180°

2x = 180 - 84

x = 48°

Therefore, measure of x = 48° will be the answer.

Answer:

x = 80

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

First, find the angle J:

60+40 = 100, J = 80 because 100+80= 180 degrees.

Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.

x + 20 = 100

x = 80 degrees.
