Can anyone please help me figure this problem out?​

Answer:

22.5

Step-by-step explanation:

Set up your proportion. You do 150x15=2,250. 2,250/100=22.5.

-10(x + 5) = 40

-10x - 50 = 40

      +50    +50

-10x  = 90

/-10    /-10

x  =  -9

Hope this helped! :D

Answer:

Correct answers:

$3265$

For this, we can use the formula

A=P0(1+rt).

We know that A=$4,000,r=15%=0.15 and t=1.5, so we can rearrange the formula for A to give

P0=A1+rt,

and substituting the known quantities gives

P0=$4,0001+0.15×1.5=$4,0001.225=$3,265.30..,

which is $3,265 to the nearest dollar.

Answer:C.4

Step-by-step explanation:

Answer:

It's B.3

Step-by-step explanation:

Substitution. With the equation Y= 9x+28 and Y= 11x+22, you substitute the x-factor with '3'. Which will give you

Y= 9(3)+28         Y= 11(3)+22

Y= 27+28           Y= 33+22

Y= 55                 Y= 55

-- i have attached a picture of the graph

- in order to graph, plug in values for x and find y

- this would create order pairs which you will plot.

some order pairs:

(0,0)

(1,3)

(2,6)

Answer: Plot the two points (0,0) and (1,3). Draw a straight line through them. The graph is shown below.

===========================================================

Explanation:

When x = 0, we have y equal to...

y = 3x

y = 3*0

y = 0

So this means (x,y) = (0,0) is one point on the line

Let's follow those steps for x = 1

y = 3x

y = 3*1

y = 3

So the point (x,y) = (1,3) is also on the line.

You can repeat this process for any x value you want; however, we only need two points to form the line. Plot (0,0) and (1,3). Then draw a straight line through both points. Extend the line as far as you can in either direction. This forms the graph of y = 3x.

You can use a graphing calculator (eg: TI83) to get the job done. Or you can use a free online resource such as GeoGebra or Desmos. I prefer GeoGebra as it offers more options. The graph shown below was made with GeoGebra.

Note that moving from point A(0,0) to B(1,3) has us move up 3 and over to the right 1. This is due to the slope of 3 = 3/1.

y = 3x is the same as y = 3x+0. It is of the form y = mx+b with m = 3 = 3/1 as the slope and b = 0 as the y intercept.

Answer:

(1) or A or whatever lol

Step-by-step explanation:

basically just plug the number in, set them equal to each other, and see if the equation is true...

1/2(-2)+3=|-2|

-1+3=2

2=2

1/2(2)+3=|2|

1+3=2

4=2

1/2(3)+3=|3|

1.5+3=3

4.5=3

1/2(-6)+3=|-6|

-3+3=6

0=6

the only one that is a true statement is x=-2

Answer:

-2

Step-by-step explanation:

just had the same question

Answer:

it is 112° .. as you will solve it like this (180-44=136) and each angle down there are equal so we will divide 136÷2 so each angle is 68° ,, finally to find x you can do it in two ways 1) (68+44) =112 or you can go with (180-68=112)

Answer:

33.3333333333

One coin would equal over 11 more would be 8.3333333333 so time that by 4

GoodLuck

Let's say we already did the work and found the result of 48*19. That result is 912.

When it comes to multiplying 0.048 and 1.9, we're going to need to do two things to transform those numbers into 48 and 19.

Move the decimal point of 0.048 exactly three spaces to the right. This is the same as multiplying by 1000. So 1000*0.048 = 48

Move the decimal point of 1.9 exactly one space to the right. This is the same as multiplying by 10. So 10*1.9 = 19

Overall, we've multiplied by 1000*10 = 10,000. This means 48*19 = 912 is 10,000 times larger compared to the result of 0.048*1.9

To fix this, we need to divide by 10,000 to get 912/(10,000) = 0.0912

Dividing by 10,000 is the same as moving the decimal point to the left four spaces. Note how 10,000 = 10^4.

I recommend using your calculator to see that 0.048*1.9 = 0.0912 which matches with the previous result we got.

Answer:

8.67 dollars per ft squared

Step-by-step explanation:

This is a fraction equal to

130 dollars ÷ 15 ft squared

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 15

130 dollars ÷ 15

15 ft squared ÷ 15

=

8.67 dollars

1 ft squared

=

8.67 dollars

ft squared

= 8.67 dollars per ft squared

Answer:

$8.67

Step-by-step explanation:

you have the the price for 15 square ft

and you are trying to get the price for 1 square ft

just divide the original price by 15

here's the equation format

130 = 15 x

solve for x

Answer:

3 ft 1 in

Step-by-step explanation:

As 12 in= 1 ft,

So, 3 in+ 10 in= 1 ft 1 in

Total= 2 ft + 1ft 1 in

= 3 ft 1 in

Answer:

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1]

{\displaystyle a^{2}+b^{2}=c^{2},}a^{2}+b^{2}=c^{2},

where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides. The theorem, whose history is the subject of much debate, is named for the Greek thinker Pythagoras, born around 570 BC.

The theorem has been proven numerous times by many different methods—possibly the most for any mathematical theorem. The proofs are diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years.

The theorem can be generalized in various ways: to higher-dimensional spaces, to spaces that are not Euclidean, to objects that are not right triangles, and to objects that are not triangles at all but n-dimensional solids. The Pythagorean theorem has attracted interest outside mathematics as a symbol of mathematical abstruseness, mystique, or intellectual power; popular references in literature, plays, musicals, songs, stamps, and cartoons abound.-Wikipedia

Answer:

according to

Step-by-step explanation:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

The question is incomplete. Here is the complete question.

The following data represents the 2011 guaranteed salaries (in thousands of dollars) of the head coaches of the final 8 teams in the 2011 NCAA Men's Basketball Championship. The data represent the 2011 salaries of basketball coaches of the following universities, entered in that order: Arizona, Butler, Connecticut, Florida, Kansas, Kentucky, North Carolina and Virginia Commonwealth. (Source: www.usatoday.com)

                  1950 434 2300 3575 3376 3800 1655 418

Compute the range, variance and standard deviation for these data.

Round your answers to the nearest integer, where appropriate.

Answer: Range = 3382

              Variance = 1785193

             Standard Deviation = 1336

Step-by-step explanation: Range is the difference between the highest value and lowest value of the set.

Range for the coaches salaries is

range = 3800 - 418

range = 3382

Variance and Standard Deviation are both the statistical measures of the spread between in the data set. In other words, they show how far the numbers in the set are from the mean of the data.

Variance is calculated as

[tex]s^{2}=\frac{\Sigma (x-\mu)^{2}}{n}[/tex]

x are the numbers in the set

μ is the mean

n is sample or population quantity

For the coaches' salaries, variance is

[tex]s^{2}=\frac{\Sigma (418-2188.5+...+3800-2188.5)^{2}}{8}[/tex]

s² = 1785192.6

Standard deviation is the squared root of variance:

[tex]s=\sqrt{s^{2}}[/tex]

Then, for coaches' salaries:

[tex]s=\sqrt{1785192.6}[/tex]

s = 1336.11

For the 2011 coaches' salaries, range, variance and standard deviation are 3382, 1785193 and 1336, respectively
