Answers

Answer 1

diameter = 4 cm

so radius r  = 4 : 2 = 2 cm

area of a circle = pi x r² ≈ 3,14 x 2² = 12,56 cm²

A line passes through the point (-2, 6) and has a slope of 6.
Write an equation in point-slope form for this line.

Answers

Answer:

y = 6x + 18

Step-by-step explanation:

so first write y = 6x + b (because you have the slope) now to find the y-intercept input the point (-2, 6) and do algebra

6 = 6(-2) + b

6 = -12 + b

b = 18

Using sampling concepts, it is found that the most representative sample of the population of interest is given by:

50 randomly selected employees at the company.

What is sampling?

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which has to involve all groups in the population.

In this problem, all employees have to be considered, no matter their department or experience on the company, hence the most representative sample of the population of interest is given by:

50 randomly selected employees at the company.

If y varies jointly as x and z when x = 5, y = 80, and z = 8, what is y when x = 16 and z = 2?
Type your answer

Answers

Hey there!

Let's make an equation

⇒y = (a)(x)(z)

y = 80x = 5z = 8

⇒ 80 = a(5)(8)

⇒ 80 = a(40)

⇒ 80 = 40a

Divide both sides by 40

⇒40a/40 = 80/40

⇒a = 80/40

Therefore, a = 2

Let's substitute into first equation

⇒y = (2)(16)(2)

y = 64

So, y = 64

Austin is building a miniatuer replica of the empire state building.The actual empire state building is 1,423 feet tall and 6,000 feet wide .If astin's replica has a width of 60 centimeters, what is the height of his empire state building replica rounded to the nearest centimeter?

Answers

Answer: 14cm

Step-by-step explanation:

From the question, we are informed that Austin is building a miniatuer replica of the empire state building and that the actual empire state building is 1,423 feet tall and 6,000 feet wide

We are further told that Austin's replica has a width of 60 centimeters. This implies that the scale of 1:100 was used where 1cm represents 100 feet

= 60:6000

= 1:100

Therefore, the height of his empire state building replica rounded to the nearest centimeter will be:

= 1423/100

= 14.23cm

= 14cm approximately

The figure D' E' F' G' (is/is not) a dilation of the figure D E F G. Thr ratios of the lengths of the corresponding sides (are not/are) equal.​

Answers

Answer:

  is a dilation

Step-by-step explanation:

One of the triangles will be a dilation of the other if corresponding sides have the same ratio. When given a series of side lengths, there are a couple of ways you can determine if the ratios are the same.

compute the ratio of the side of one figure to the corresponding side of the other figureput corresponding side lengths in order around the figure, and remove any common factor from their values.

Sometimes the latter approach is easier.

DEFG ratios are 16 : 32 : 28 : 12 = 4 : 8 : 7 : 3 . . . . . . remove a factor of 4

D'E'F'G' ratios are 44 : 88 : 77 : 33 = 4 : 8 : 7 : 3 . . . . remove a factor of 11

The figure D'E'F'G' is a dilation of the figure DEFG. The ratios of the lengths of the corresponding sides are equal.​

Answers

Hi there! Hope this helps, and if it does, please mark brainliest!

Answer:

2 boxes

Step-by-step explanation:

There are roughly 28 grams in an ounce. So if you have 12 ounces, times 28 by 12, which is 336, so you need 336 grams of raisins. Divide by 170, the number of grams in one box, which would be 1.98 boxes, but you have to round up, so you would need two boxes.

Two identical rectangular prisms and two identical cubes are joined. Answer the questions to find the new solid’s surface area. The numbers are 9 and 4

Answers

The surface are of the new solid formed by the joining of two identical cubes having a surface area of 294 cm² is: 490 cm²

What is the Total Surface Area of a Cube?

Total surface area of a cube = 6a², where a is the length of each of the sides.

Given:

Surface area of each identical cube = 294 cm²

Find the length of each side:

6a² = 294

a² = 294/6

a² = 49

a = √49

a = 7 cm

Surface area of the new solid = surface area of the two identical cubes - 2(area of the surface where both are joined)

Surface area of the new solid = 2(294) - 2(7²) = 490 cm²

Answer:

A.1

Step-by-step explanation:

those jelly beans are big.. its either 1 or 10 like 17cm is as long as your hand(just your hand and fingers not ur arm)

so A.

The reasonable upper limit of the bean jar is the same as the height of the jar so it will be 17cm so none of the given options will be correct.

What is volume?

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

The volume of cuboid = length × height × width.

The volume of the cube = side³.

Given a jar with a square base

Length = 12.5 cm

Width = 12.5cm

Height = 17 cm

The jelly beans will cover all heights of the jar so the maximum height of the jelly will be the same as the height of the jar.

Hence "The reasonable upper limit of the bean jar is the same as the height of the jar".
