can somebody please help me with this question

Answer:

$33.75

Step-by-step explanation:

22.9% of $43.75 = $10.0

43.75 - 10.0 = $33.75

Hope that helps

Answer:

$35.60

Step-by-step explanation:

I cross multiplied related numbers:

[tex]\frac{43.75}{x}[/tex]=[tex]\frac{122.9}{100}[/tex] cross multiply

4375=122.9x, divide both sides by 122.9

35.598=x round to hundredths

35.60

So, here we have that there are 175+63 = 238 birds in total.

We want to know the ratio of ducks to the total number of birds flying overhead. There are 175 ducks for a total of 238, so the ratio is:

175:238

Using vertical angles, it is found that:

A. The solution for y is of y = 4.

B. The angle measures are given as follows:

If two angles are opposite by the same vertex in crossing segments, these angles are called vertical angles, and they are congruent, that is, they have the same measure.

In the context of this problem, the angles of 6y + 42 and of 66 are vertical, hence the value of y is calculated as follows:

6y + 42 = 66

6y = 24

y = 24/6

y = 4.

Angles A and C are supplementary, meaning that the sum of their measures is of 180º, hence:

<C + 66º = 180º

<C = 180º - 66º

<C = 114º.

Angles C and D are vertical, hence the measure of angle D is calculated as follows:

<D = 114º.

option d is the correct answer

Answer:

This is a 30 60 90 triangle. They are saying the hypotenuse is 3x + 6 and the shortest side is 8x - 4. In a 30 60 90 triangle, the hypotenuse is 2 times the short side meaning that/

3x + 6 = 16x - 4

Answer:

7n-18

Step-by-step explanation:

The working out is attached. Hope it helps!

Answer:

n = 13

Step-by-step explanation:

For this, you need to square all of the numbers and then add them together. Most of the time, you can put them into a calculator but I will work it out below.

Squaring means multiplying a number by itself, so we get:

3² + 4² +12² =n²

Turns into:

(3*3) + (4*4) +(12*12) = n²

Then work out the multiplication:

9 + 16 + 144 = n²

Add everything together

169 = n²

Now take the square root of each side:

[tex]\sqrt{169} =\sqrt{n^{2}}[/tex]

This comes out to be:

± 13 = n

The question asks for the positive number, so you answer is:

n = 13

The slope of the line to represent the volume of water in a pool over time would described as -10

From the given table we have to choose points to find the slope of the line

The domain is defined as the set of possible inputs of the function.

The range is defined as the set of all possible outputs of the function.

The slope of the line is the change in y coordinate with respect to the change in y coordinates

Slope of the line m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Where m is the slope of the line

[tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] are the coordinates of the two points

We have to choose two points

The two points (2,44) and (4,26)

m = [tex]\frac{26-46}{4-2}[/tex]

m = -20/2

m = -10

Hence, the slope of the line to represent the volume of water in a pool over time would described as -10

From the graph, we can see that the set of ordered pairs which belongs to the line are

D). (2, 100), (3, 150), (5, 250)

Because x-axis is the first coordinate and y-axis is the second coordinate. In options B and C, they are

arranged in the wrong place. In option A, point (3,125) doesn´t belong to the line.

First solution

(x-3)=11

x=11+3

Second solution

-(x-3)-11

multiply by -1 both sides

x-3=-11

x=-11+3

Step-by-step explanation:

The probability that rose identifies all 3 cards in the correct order is 1/132,600 by the concept of permutation.

It is the separate arrangements of a given number of associates taken all at once, or some of them, or just a few of them. There are two possible meanings, AB and BA, for instance, if we have the two elements A and B.

Following the arrangement of 'r' items from a total of 'n' elements, the number of permutations is,

nPr = n! / (n – r)!

Here to obtain the probability in correct order use permutation formula

Recall that, Probability is calculated as favorable outcomes divided by all possible outcomes.

Favorable number of outcomes = 1 (as only one order is correct)

Total outcomes = 52p3 (since 3 cards to be arranged from pack of 52)

So, the probability of rose identifies all 3 cards in correct order =1/52p3

Probability = [tex]\frac{1}{52!/(52-3)!}[/tex]

Probability = 49! /52!

Probability = 49! /52*51*50*49!

Probability = 1/52*51*50

Probability = 1/132,600

Therefore, the probability that rose identifies all 3 cards in the correct order is 1/132,600.

slope = 3/7

Step-by-step explanation:

Locations of points: (-4 , 1) and (3 , 4)

slope = rise / run

between two plotted points this means that:

slope = change in y / change in x

slope = (4 - 1) / (3 - (-4))

slope = (4 - 1) / (3 + 4)

slope = 3/7

The percentage of players serves were between 115 mph and 145 mph is approximately 16%.

Given :

The statistician reported that the mean serve speed was 100 miles per hour

the standard deviation of the serve speeds was 15 mph

Assume that the statistician also gave us the information that the distribution of serve speeds was mound-shaped and symmetric

To find :

What percentage of the player's serves were between 115 mph and 145 mph?

Solution :

μ =100

σ = 15

P ( 115 < x <145)

= P ( [tex]\frac{115-100}{15}[/tex] <  x-μ /6 <[tex]\frac{145-100}{15}[/tex] )

= P ( [tex]\frac{15}{15}[/tex] < z < [tex]\frac{15}{15}[/tex] )

= p ( 1<z<3)

= p( z<3)-p(z-1)

=0.9987-0.8413

=0.1574

p ( 115<xx<145)= 15.74 %

p( 115<x<145)= approximately 16%

The percentage of players serves were between 115 mph and 145 mph is approximately 16%.

The ratio between cups of beans and cups of rice is 10/13 . Option C

A ratio can described as an ordered pair of numbers, like y and z, that is written mathematically in the form y / z where the denominator of the fraction is not equal to zero.

It is known to describe the number of times an element or number contains another number proportionally.

It is also seen as the comparison of two quantities, elements or numbers that has the same units and likewise, explains how much one of the elements or quantity is found in the another one.

This is done based on their sizes or magnitudes.

A proportion is a mathematical equation with two ratios set equivalent or equal to each other.

Given that;

Beans = 2 1/ 2 cups

Rice = 3 1/4 cups

Convert to mixed fractions;

Beans = 5/2

Rice = 13/4

Now, divide the cups of beans by that of rice;

= 5/ 2 ÷ 13/4

= 5/2 × 4/13

= 10/13

Hence, the ratio is 10/13
