Find the value of x.

Answer:

[tex]Boys = 1 /4[/tex]

[tex]Total =112[/tex]

Step-by-step explanation:

Given

[tex]Girls= 3/4[/tex] ---  missing information

[tex]Boys = 28[/tex]

Solving (a): The fraction that are boys

We have:

[tex]Girls= 3/4[/tex]

This implies that

[tex]Boys = 1 - Girls[/tex]

[tex]Boys = 1 - 3/4[/tex]

[tex]Boys = 1 /4[/tex]

Solving (b): Students in the class

If 1/4 are boys, then:

[tex]Boys = \frac{1}{4} * Total[/tex]

We also have that: [tex]Boys = 28[/tex]

So:

[tex]28= \frac{1}{4} * Total[/tex]

[tex]28 * 4 = Total[/tex]

[tex]112= Total[/tex]

[tex]Total =112[/tex]

Complete Question:

The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.

Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?

Answer:

The height is 36 meters

Step-by-step explanation:

Given

[tex]y = 24 * \frac{x}{10}[/tex]

Required

The interpretation of the question is to determine the value of y when x = 15

Substitute 15 for x in: [tex]y = 24 * \frac{x}{10}[/tex]

[tex]y = 24 * \frac{15}{10}[/tex]

[tex]y = 24 * 1.5[/tex]

[tex]y = 36[/tex]

The height is 36 meters

Number of strawberry candy = [tex]\bold{8\ pieces}[/tex]

Number of rhubarb candy = [tex]\bold{7 \ pieces}[/tex]

Find the number of ways for equally distributing candy to all 5 children

Using formula:

[tex]\to \bold{_{n} C_{r}=\frac{n !}{r!(n-r) !}}[/tex]

Calculating the distributing way for strawberry candy:

[tex]\to \bold{_{8} C_{5}=\frac{8 !}{5!(8-5) !}}[/tex]

           [tex]\bold{=\frac{8 !}{5! \ 3 !}}\\\\\bold{=\frac{8 \times 7 \times 6 \times 5!}{5! \ 3 \times 2\times 1}}\\\\\bold{=\frac{8 \times 7 \times 6 }{ 6}}\\\\\bold{=8 \times 7}\\\\\bold{=56}[/tex]

Calculating the distributing way for rhubarb candy:

[tex]\to \bold{_{7} C_{5}=\frac{7 !}{5!(7-5) !}}[/tex]

           [tex]\bold{=\frac{7 !}{5! \ 2 !}}\\\\\bold{=\frac{7 \times 6 \times 5!}{5! \ 2\times 1}}\\\\\bold{=\frac{ 7 \times 6 }{ 2}}\\\\\bold{=7 \times 3}\\\\\bold{=21}[/tex]

Answer:

9600

Step-by-step explanation:

y varies inversely with the square of x

y=k/(x^2)

for some non-zero constant k

y=6 when x=4

6=k/(4^2)

k=96

y=96/(x^2)

x=0.1

y=96/(0.1^2)

y=9600

Answer:

x = 2

y = 152°

Step-by-step explanation:

✔️9x + 10 = 15x - 2 (corresponding angles theorem)

Collect like terms

9x - 15x = -10 - 2

-6x = -12

Divide both sides by -6

x = -12/-6

x = 2

✔️y + (15x - 2) = 180° (same-side interior angle theorem)

Plug in the value of x

y + (15*2 - 2) = 180

y + 28 = 180

y = 180 - 28

y = 152

Step-by-step explanation:

Insurance costs are influenced by any factor that can reasonably be tied to the cost of claims made against an insurance policy. These costs are carefully analyzed by insurance companies to determine correlations that may be influential.

__

In general, women have different driving habits than men, so gender has an influence on insurance costs.

Some areas of a city have different statistics related to vandalized or stolen vehicles, so may influence insurance costs. Certain areas may have different accident statistics, or may experience different kinds of accidents, so repair costs may differ by where you live or where you drive.

Some cars are more expensive to repair than others. Any car with custom features (stereo, upholstery, paint) will likely cost more to repair (and may be subject to more vandalism).

So, all of the above influence insurance costs.
