Answer:

133.78684807256

Step-by-step explanation:

step 1: We need the assumption that 44.1 is 100% since it is our output value

step 2: We need to represent the value we seek in x

step 3: From step 1, it follows that 100% = 44.1

step 4: In the same vein x% = 59

step 5: This give us a pair of simple equations:

100% = 44.1 (1)

x% = 59 (2)

step 6: by simplify dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

[tex] \frac{100}{x} = \frac{44.1}{59} [/tex]

step 7: Taking the inverse (or reciprocal) of both sides yields

[tex] \frac{x}{100 } = \frac{59}{44.1} [/tex]

= x = 133.78684807256

Therefore, 59 is 133.78684807256% of 44.1

Answer:

h(3) = - 1

Step-by-step explanation:

To evaluate h(3), that is x = 3 in the interval x ≥ 1 , then

h(x) = - x + 2 , thus

h(3) = - 3 + 2 = - 1

Then h(3) = - 1

Answer:

28.4in³

Step-by-step explanation:

Volume of the square based pyramid = L²H/3 where;

L is the length of a side of the square base

H is the height of the prism

Given

Perimeter of the base = 13.4 in

Height of the pyramid = 7.6in

First we need to get the length of the square base

Perimeter of a square = 4L

13.4 = 4L

L = 13.4/4

L = 3.35 in

Next is to find the required volume of the pyramid

V = L²H/3

V =  3.35²(7.6)/3

V = 85.291/3

V =  28.4 in³

Hence the volume of the pyramid to nearest tenth is 28.4in³

Answer:

D.2

Step-by-step explanation:

A function assigns the value of each element of one set to the other specific element of another set. The correct option is D.

A function assigns the value of each element of one set to the other specific element of another set.

A vertical asymptote is the value of x for which the function is not defined.

The vertical asymptotes that the graph of this function F(x)=2/x(x+1) will be 2 because x(x+1) is of the second degree.

Hence, the correct option is D.

Answer:

The coordinates of the point P  in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:

Step-by-step explanation:

Let P be the point.

As the point P is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6

i.e.

(x₁, y₁) = (-2,-8)

(x₂, y₂) = (5,-1)

Rise = y₂ - y₁ = -1 - (-8) = -1 + 8 = 7

Run = x₂ - x₁ = 5 - (-2) = 5 + 2 = 7

1 : 6 ratio means the point P lies at

[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]

Thus,

rise for P = 7 × 14% = 1

run for P =  7 × 14% = 1

Thus, coordinates of P will be:

x = -2 + 1 = -1

y = -8 + 1 = -7

Thus,

The coordinates of the point P  in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:

Answer:

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200

Answer:

[tex]A=254.46\ cm^2[/tex]

Step-by-step explanation:

Given that,

The diameter of the pizza, d = 18 cm

We need to find the square cm of cheese layer does she need to put on the pizza.

We know that the area of the circle is given by :

[tex]A=\pi r^2[/tex]

Where

r is the radius of the circle

Here, r = 9 cm

So,

[tex]A=\pi (9)^2\\\\A=254.46\ cm^2[/tex]

So, the area of the pizza is [tex]254.46\ cm^2[/tex].

Answer:

84

Step-by-step explanation:

[tex]7 + (15 - 5) \times (10 - 6) \times \frac{1}{2} + 5 \times 10 = 84[/tex]

Answer:

The answer is 84 inches Squared!

Step-by-step explanation:

Here is the explanation to the answer:-

All you have to do is divide the whole figure into some parts!

Here is what I have divided the figure into.

The triangle area is 1/2 * L*H

The measurements are 1/2 * 4*3 = 6in Squared.

                         ( The Next Shape To The Triangle)

 Rectangle area is L*B

The Measurements are 4*7 = 28inches Squared.

                          (The next shape to the rectangle)

Rectangle area is L*B

Measurements are 5*4 = 20inches squared.  

                                    (Above Shape of the rectangle)

Area of rectangle is L*B

Measurements are 6*5 = 30 Inches Squared.

    Now, add all the areas of the figure:-

6 + 28 + 20 + 30 = 84 Inches Squared.

Thanks, and hope this helps.
