Answer:

x = 7

Step-by-step explanation:

Let

x = the unknown number

double it :

2x

add 11:

2x + 11

I get 25:

The equation is

2x + 11 = 25

2x = 25 - 12

2x = 14

Divide both sides by 2

x = 14/2

x = 7

Answer:

$6.30

Step-by-step explanation:

Answer:

The tip should be $6.30

Step-by-step explanation:

We can find 15 percent of 42$ by multiplying 42 by 0.15 (this is another way of writing down 15%) and so we get...

(42)(0.15) = 6.3

Therefore the tip should be $6.30

Answer:

D

Step-by-step explanation:

since this feels like a sequence, a1 should be the first Expression to the arimethic sequence and the rest should be the (n - 1)d so I think it should be 1/2 + 4(an - 1)

note: arimethic sequence formula is a + (n - 1)d

Answer:

D = 3J and D + 20 = 2(J + 20) - 2

Step-by-step explanation:

the first part is obvious. Dad is 3 times as old as his son = D=3J

the second part you're adding 20 years to both Dad and Jim = D + 20 and J+20. now Dad is 2 less than twice Jim's age -> D+20 = 2(J+20)-2

Answer: the second one i may be wrong but i can relate to you ❤

Answer:

3rd box plot

Step-by-step explanation:

The maximum is 18 and minimum is 2, and the only box plot with the maximum of 18 is the 3rd one.

Max = 18

Min = 2

Median (middle number in the data set) (also the line in the middle of the box) = 8

Answer:

See answers below

Step-by-step explanation:

1) The typr of triangle in a semicircle is a right angle. Hence the measure of  m<ABC  is 90degrees

2) m<DEF = 1/2(144)

m<DEF = 144/2

m<DEF = 72degrees

3) From the trinagle

4x+3 + x+7 +90 ==180

5x + 100 = 180

5x = 180-100

5x = 80

x = 80/5

x = 16

<QRD =  x+7

m<QRD = 16 + 7

m<QRD = 23degrees

4)  Angle in the same segment are equal

5x-37= 3x+1

5x - 3x = 1+37

2x = 38

x = 38/2

x =19

arc NM = 2m<P

arc NM = 2(3x+1)

Answer: 40%

48 cars

Step-by-step explanation:

120 divided b7 15 = 8, 8 times 5 = 48

48/120 is 40%

40% percent of the cars were previously damaged in a accident out of 120 in the lot. Do 120 ÷ 15 then divide that by 6 to get your answer of 40%

The best estimate of the percent of the used-car lot's vehicles that have previously been in an accident is 40%

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.

It is given that

A used car lot has 120 vehicles for sale. A sample of 15 of these vehicles finds that 6 of them have previously been in an accident.

if in 15 cars 6 of them have been in an accident

then in 120 vehicles = 120*6/15

48 cars have been in an accident

Now the best estimate of the percent of the used-car lot's vehicles that have previously been in an accident.

(48/120 ) *100

= 40%

Therefore the percent of the used-car lot's vehicles that have previously been in an accident is 40% .

Answer:

Step-by-step explanation:

This is a right triangle problem of the simplest variety in that we only need Pythagorean's Theorem to solve for the missing side.

Pythagorean's Theorem says that the sum of the lengths of the 2 legs squared will equal the length of the hypotenuse squared. For us that looks like this:

[tex]40^2+10^2=h^2[/tex] and

[tex]1700=h^2[/tex] so

h = 41 feet, rounded to the nearest foot
