Answer 1

Answer: 254.34 yd

Step-by-step explanation:

If the diameter is 18 yd then the radius:

radius = diameter/2

r = 18/2

r = 9 yd

So the area is:

[tex]A = \pi r^2\\= \pi (9)^2\\= (3.14)(81)\\ =254.34 \hspace2yd[/tex]

Therefore, the area of the circle is 254.34 yd

You are wrapping a birthday gift that is packaged in a specially made pyramid-shaped box. The base of the box measures 10 inches by 10 inches and the slant height is 6 inches. How much paper do you need to wrap the box?

Answers

Answer:

2 1/4

Step-by-step explanation:

The amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches

What is the surface area of cuboid?

Let the three dimensions(height, length, width) be x, y,z units respectively.

The surface area of the cuboid is given by

[tex]S = 2(a\times b + b\times c + c\times a)[/tex]

A box is usually in shape of a cuboid.

For this case, its dimensions are 10 inches, 10 inches, and 6 inches.

The amount of wrapper we need is approx same as the area of its surface (assuming we're going to measure the paper needed in terms of its area).

Thus, we get:

Amount of the paper we need to wrap the considered box = surface area of that box = surface area of cuboid of dimension 10 inch by 10 inch by 6 inches = S (say), then:

[tex]S = 2(10\times 10+ 10\times 6 + 6\times 10)\\S = 440[/tex](in sq. inches)

Thus, the amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches

Find the cost of painting a cubical block of side length 3.2 cm, if painting costs $5 per cm2.

Since painting is done on outer surface of cubical block we will have to find its surface area which is given by-

Maya started to run on a treadmill after setting its timer for 99 minutes. The display says that she has finished 27% of her run. How many minutes have gone by? Round your answer to the nearest tenth. minutes

Answers

Answer:

26.73 minutes have gone by

Step-by-step explanation:

Use cross multiplication

x        27

----  =  -----    since we are trying to find how many minutes out of 99 passed,

99      100   place x for the missing digit

solve

x times 100 = 99 times 27

simplify

x100 = 2673  x times 100 is just x100 since we don't know what x is, and 99  

                       times 27 is 2673

figure for x

x100 = 2673  to find x, it needs to be alone (x is very introverted :'> ) we can

  ----     -------  remove 100 by doing the opposite of what 100 is doing to the  

 100     100   x. Since it is 100 TIMES x, we will remove it by dividing 100 by        

                      100 (which crosses it out) and then 2673 divided by 100. 2673      

 x = 26.73     divided by 100 gives us 26.73, so x equals 26.73.

Find the y-intercept of the line 19x - 13y = 26.
Write your answer as an integer or as a simplified proper or improper fraction, not as an
ordered pair.

Answers

Answer:

y - intercept = - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

19x - 13y = 26 ( subtract 19x from both sides )

- 13y = - 19x + 26 ( divide terms by - 13 )

y = [tex]\frac{19}{13}[/tex] x - 2 ← in slope- intercept form

with y- intercept c = - 2

The y-intercept of the line equation 19x - 13y = 26 is 2.

Given that, the y-intercept of the line 19x - 13y = 26.

What is a y-intercept?

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

The given equation can be written in standard form as

13y=19x-26

⇒ y=19/13 x-26/13

⇒ y=19/13 x-2

So, y-intercept =2

Therefore, the y-intercept of the line equation 19x - 13y = 26 is 2.

At the beginning of Jack's diet, he was 257 pounds. If he lost 3 pounds per week, find his weight after
12 weeks.

Answers

Answer:

A loss of weight means we subtract from Jack's current weight.

A loss of weight means we subtract from Jack's current weight. New Weight = Current Weight - Weight Loss per week * number of weeksNew Weight =257 - 3*12New Weight =257 - 36New Weight = 221

[times 12] 3 pounds= 1 week. {times 12}
