Answer:

to make it perpendicular the slope as to be -5 (opposite reciprocal of the original)

Ratio of the sides of the triangles,

2 : 3 : 4

Let's consider each side to be

2x,3x and 4x

Therefore the perimeter of the triangle is,

2x + 3x + 4 x = 9x

The shortest side is 15 inches.

We know that the smallest value in the above ratio is 2

Therefore,

2x = 15 inches

x = 7.5 inches

☞Perimeter of the triangle

= 9x

= 9 * 7.5 inches

= 67.5 inches

Answer:

p=7

Step-by-step explanation:

5p-1=2p+20 first add 1 to both sides to get 5p=2p+21, then subtract 2p from both sides to get 3p=21, then divide by three to get p=7

Answer:

The actual length of the living room is 24 feet.

Step-by-step explanation:

Scaling

The scaling on a blueprint for an apartment is:

1 inch = 4 feet

This means every 1 inch measured on the blueprint corresponds to 4 feet on the real length of the apartment.

We know the length of the living room in the blueprint is 6 inches, thus the real dimension of the living rooms is:

6 * 4 = 24 feet

The actual length of the living room is 24 feet.

Answer:

The closet equivalent of the ratio of 'a' to 'c' is:

[tex]\frac{a}{c}=1.680\:[/tex]

Step-by-step explanation:

Given

i.e.

a=0.63x

i.e.

c=3/8x

Hence,

[tex]\frac{a}{c}=\frac{0.63x}{\frac{3}{8}x}[/tex]

[tex]\frac{a}{c}=1.680\:[/tex]

Thus, the closet equivalent of the ratio of 'a' to 'c' is:

[tex]\frac{a}{c}=1.680\:[/tex]

Answer:

A

Step-by-step explanation:

Multiply 15 by 8 to get 120. 120 + 15 × 11 = 285. 285 + 15 × 22 = 615. 615 + 20 × 7 = 755. 755 + 20 × 6 = 875. 875 + 20 × 14 = 1,155. 1,155 - 292.58 = 862.42. 862.42 - 292.58 = 569.84. Remember PEMDAS.

Answer: Your answer is 365

Step-by-step explanation: Hoped this helped you. And have a wonderful day!!!

The final result of 903 - 538 is 365.

To subtract 538 from 903, you perform the following calculation:

903 - 538 = 365

To explain the process, you start with the number 903 (minuend) and subtract 538 (subtrahend) from it.

1. Begin with the units place: 3 - 8. Since 8 is greater than 3, you borrow 1 from the tens place. The units place becomes 3 + 10 (borrowed) - 8 = 5.

2. Move to the tens place: 0 (in 903) - 3 (borrowed) - 3 (from 538) = -6.

3. Lastly, the hundreds place: 9 - 5 (from 538) = 4.

Answer:

The sales tax included in the sale of the car is 15.76%.

Step-by-step explanation:

Given that the MSRP of the car bought by Nancy Boone is $ 27,853, and the total cost of the car was $ 32,591.22, including sales tax, plus a dealer prep charge of $ 278.50 and a title fee of $ 25, to find out the percentage of sales tax ( which does not include the title fee) it is necessary to perform the following calculation:

32,591.22 - 25 = 32,566.22

27,853 + 278.5 = 100

32,566.22 = X

28,131.5 = 100

32,566.22 = X

(32,566.22 x 100) / 28,131.5 = X

3,256,622 / 28,131.5 = X

115.76 = X

115.76 - 100 = 15.76

Thus, the sales tax included in the sale of the car is 15.76%.

C. middle school grades

Step-by-step explanation:

Colleges want to see if students challenged themselves by taking rigorous courses, and they also want to know what kind of grades students were able to maintain. They also like to take into account the scores you get on standardized tests because these tests can give a relatively accurate idea of a student's mastery of certain subjects. The only thing they don't pay attention to are the grades you earned in middle school. Since these grades aren't very recent, they don't serve as an accurate measure of a student's academic ability, which is why colleges prefer to look at the grades a student earns during their time in high school.

Answer:

x = 3, y = 3

Step-by-step explanation:

Elimination method to find x:

  (7x + 3y = 30) * -1      ===>                              -7x - 3y = -30

                                                                          -2x + 3y = 3                    

  add two equations to eliminate y             ______________

                                                                                 -9x = -27     ===>   x = 3

substitution to find y:  

  -2x + 3y = 3

  -2(3) + 3y = 3

  -6 + 3y = 3

  3y = 9

    y = 3

Elimination method to find y:

  (7x + 3y = 30) * 2         ===>                           14x + 6y = 60

  (-2x + 3y = 3)  * 7         ===>                         -14x + 21y = 21

  add two equations to eliminate x             ______________

                                                                              27y = 81      ===>   y = 3

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

Step(i):-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that [tex]\sqrt{p(1-p}\leq \frac{1}{2}[/tex]

Step(ii):-

Given margin of error  = 2 % =0.02

The margin of error is determined by

          [tex]M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }[/tex]

         [tex]0.02 = \frac{\frac{1}{2} }{\sqrt{n} }[/tex]

        [tex]\sqrt{n} =\frac{1}{2 X0.02}[/tex]

        √n = 25

squaring on both sides, we get

       n = 625

Answer: No. Zeke found the LCM to be the product of two and eight but because eight is a multiple of two the LCM is eight so the first day he will have both clubs is the 8th day of the month

Step-by-step explanation:

all you have to do is fine the least common multiple of 2 and 8 which is eight so obviously zeke is incorrect because they said the least common multiple was 16 and it is not. zeke multiplied 2 and 8 which is not what you’re supposed to do to get the lcm.

Let 2x = Paul

Let x = Colin

Let 5x = Brian

2x + x + 5x = 78.40

8x = 78.40

x = 78.40 ÷ 8

x = 9.8

Brian gets 5(9.8) which is 49.

Colin gets 9.8.

Brain over Colin means 49/9.8 = 5.

Brain gets £5 more than Colin in terms of a tip.
