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.

What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6?

Answers

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:

(x, y) = (-1, -7)

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:

(x, y) = (-1, -7)

What percent of 59 is 44.1? Round the answer to the nearest
hundredth of a percent if necessary.

Answers

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

How many vertical asymptotes does the graph of this function have?F(x)=2/x(x+1)

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.

What is a Function?

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.

D. In art class, we all had to draw the still life, or we would not be ready to paint it the next day.

Answers

Answer: It's A if not put B

Step-by-step explanation:

Since correlative conjunctions are used to connect parts of a sentence with equal value, we only need to use a comma when two independent clauses are being connected with correlative conjunctions.Correlative conjunctions include pairs such as “both/and,” “either/or,” “neither/nor,” “not/but” and “not only/but also.

Solve the equation for the red variable

Answers

i think c = p+ r because you firstly have to rearrange the equation so that you isolate the -c. which means you get -c = p-r because you have to change the sign of the r when you switch it. so -c = p-r, but to find c that isn’t minus you need to change the sign on both sides. therefore, the answer should be c = p+r.

Tiffany makes a round pizza. She wants to put a cheese layer on the pizza. If the pizza has a diameter of 18 cm, how many square cm of cheese layer does she need to put on the pizza?

Answers

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].

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?​

Answers

Answer:

200 litres

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

Find the volume of a pyramid with a square base, where the perimeter of the base is 18.5 ft and the height of the pyramid is 7.6 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

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
