Can someone help me with this, I will mark you as brainliest!

Answer & Step-by-step explanation:

First, we must know the formula for finding the circumference of a circle.

Circumference = dπ

(d) represents your diameter. In order to find the diameter, you have to multiply the radius by 2 because the radius is half the size of the diameter.

The radius we are given is 15. So well do 15 multiplied by 2.

15 * 2 = 30

Now, since we have ti put the answer in terms of pi, then you are just going to leave 30 as it is and add the pi symbol.

C = 30π

Answer:

$11

Step-by-step explanation:

Total members = 50 ,    Raised amount = $680

If school gives $130 then all the 50 members will pay the remaining amount.

Remaining amount to be paid by the 50 members = $680 - $130 = $550

50 members = $550

1 member = $550/50

1 member = $ 11 ( Answer)

Option (2)

Step-by-step explanation:

Parent function has been given as,

f(x) = [tex]\sqrt{x}[/tex]

When translated by 3 units left,

f(x + 3) = [tex]\sqrt{(x+3)}[/tex]

g(x) = [tex]\sqrt{(x+3)}[/tex]

If the translated function is stretched vertically by a scale factor = k

New function will be,

g'(x) = [tex]k\sqrt{(x+3)}[/tex]

Since a point (1, 4) passes lies on the transformed function.

g'(1) = [tex]k\sqrt{(1+3)}[/tex]

4 = 2k

k = 2

Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.

Option (2) will be the answer.

Answer:

49.28.

Step-by-step explanation:

11% = 10% + 1%

So 11% of 448 = 44.8 + 4.48

= 49.28.

The best estimate of 11% of 448 is 49.28.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred.

11% of 448 = 11 / 100 × 448 = 0.11 × 448

= 49.28

Hence, the best estimate of 11% of 448 is 49.28.

Hi there!

The correct answer is: B. Convex Octagon

Step-by-step explanation:

The figure first classifies as an octagon because it has 8 sides.

Next you can tell whether or not it is concave or convex by remembering: concave has a "cave" in it.

Concave or Convex

A convex octagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. When any internal angle is greater than 180° it is concave.

The given figure is convex octagon. Therefore, option B is the correct answer.

An octagon can be defined as a polygon with eight sides, eight interior angles, and eight vertices. When all the sides and angles of an octagon are equal in measurement, it is called a regular octagon.

Every polygon is either convex or concave. Convex octagons bulge outwards, whereas concave octagons have indentations (a deep recess). Convex octagons are those in which all the angles point outwards. A regular octagon is an example of a convex octagon. The octagon in which at least one of its angles points inwards is a concave octagon.

In the given figure, there are 8 sides and 8 angles.

Therefore, option B is the correct answer.

Answer:

Step-by-step explanation:

2w-4=10

2w=14

w=7

(2y-5)+67+48=180

2y-5+115=180

2y+110=180

2y=70

y=35

2x+17=(2y-5)

2x+17=(2*35-5)

2x+17=(70-5)

2x+17=65

2x=48

x=24

z=48, since angle BIG is congruent to angle RAC

Answer:

9.110° and y are the same(alternate angles)

thus y=110°. 110+x=180(seplementary angles). thus x=180-110=70°

z(alternate)=70°

10.y=78°. x=(180-78)=102°. z=102°

11.x=83°. y=(180-83)=97°. z=97°

12.y=37°. x=(180-37)=143. z=143°

to confirm the answers all angles in a circle at the centre add up to 360°

Answer:

x = 6

Step-by-step explanation:

The scale factor is

28/8 = 7/2

We take the ratio of the larger side over the smaller side

Using ratios we can find the sides

28         21

----- = ---------

8           x

Using cross products

28x = 21*8

28x =168

Divide each side by 28

28x/28 = 168/28

x =6

Answer: 24 hours

Step-by-step explanation:

You multiply 30 by 4/5, since this is inverse.

If it took 4 bricklayers to build a brick wall in 30 hours, then it would 24 hours for 5 bricklayers to build a brick wall.

The amount of time is reduced down to 4/5 of the first time because there are now 5 bricklayers instead of four.

Answer:

It would take 24 hours for 5 bricklayers to build a wall.

Step-by-step explanation:

We can deduce the number of hours the bricklayers needed to build a wall because they are inversely proportional.

In other words, more bricklayers will result in fewer work hours.

4 bricklayers × 30 hours = 120 bricklayers hours

120 bricklayers hours / 5 bricklayers = 24 hours

Therefore, it would only take 24 hours for 5 bricklayers to build a wall. (Which is 6 hours faster since one person joined the workforce to help the others).

Answer:

P(A and B) = 0.1344 = 13.44%

Step-by-step explanation:

If the chances are disjoint and you want the chance of both happening, you can multiply their individual chances.

It's easiest to express them as a fraction, i.e., 64% = 0.64 and 21% = 0.21

P(A and B) = 0.64 * 0.21 = 0.1344 which is 13.44%

yo hice el examen y la tuve mal pero me dijo cual era la correcta y es (30,38)

I do the exam and I heve it wrong but the exam put what was the correct answer and it is (30,38)

option B

Equation of Linear Regression line is

y=1.14 x + 3.805

so, (30,38)  is an approximate extrapolation for x = 30 from the line of best fit.

A line of regression is that line which passes through none of the points, few points or all the points in the two dimensional coordinate plane.It tells value of one variable when another variable is known.

here, we have,

A line of best fit is drawn for the set of points shown on the graph.

from the given information,

we get,

for, x=30

y=1.14 × 30 +3.805

y=34.20 +3.805

y=38.005

y=38 (approx)

Equation of Linear Regression line is

y=1.14 x + 3.805

so, (30,38)  is an approximate extrapolation for x = 30 from the line of best fit.

So, Ordered pair is , (30,38)

Answer:

Step-by-step explanation:

If two angles are complementary, the sum of measures of  two angles is 90

Using this, you can find the angles

Answer:

Two Angles (A and B) are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. This is:

A + B = 180

so

A=180 - B or

B=180-A

Examples:

• 60° and 30° are complementary angles.

• 5° and 85° are complementary angles.

Type of lines ?  Not the best question.

Answer: Perpendicular, first choice

The little 90 degree angle indicator at the intersection marks these lines as meeting at a right angle, which is called perpendicular.
