Answer:

27 children

Step-by-step explanation:

For every 9 children, there are 4 adults. Those numbers added together equal 13. Now, if we divide the total number of adults and children by 13, we will get the number of how many groups there are of 9 kids and 4 adults.

39 / 13 = 3

There are 3 groups of 9 kids and 4 adults, which means to find the total number of children, we have to multiply 3 by 9.

3 * 9 = 27

Therefore, there are 27 children total. I know this was probably really confusing, but I hope it helped in some way! Have a lovely day!! :)

Answer:

p = 35

Step-by-step explanation:

the midsegment WY is half the measure of VZ , that is

WY = [tex]\frac{1}{2}[/tex] VZ ( substitute values )

p - 21 = [tex]\frac{1}{2}[/tex] (p - 7) ← multiply through by 2 to clear the fraction

2p - 42 = p - 7 ( subtract p from both sides )

p - 42 = - 7 ( add 42 to both sides )

p = 35

Answer:

Step-by-step explanation:

No choice is given but here is the general interpretation.

Y-intercept is where the plot crosses the y-axia at x=0. In this case, x is T which represents number of TVs owned by the family. T=0 meaning there is no TV and B = 96.66 is the one month's electric bill in dollars for all other appliances in the home.

Given function

Now

Compare to slope intercept form y=mx+b

Here y intercept may be the fixed charge .

Answer:

[tex]a_n=\frac{1}{8} (2^{n-1})[/tex]

Step-by-step explanation:

This is a geometric sequence.  You start with the first term, 1/8, then multiply it by 2 to get 1/4, then double that to get 1/2, etc.

The number you multiply by is called the common ratio.  In this case, the common ratio is 2.

A formula for the general (nth) term is:  [tex]a_n=a_1 r^{n-1}[/tex].

[tex]a_1=1/8\\r=2[/tex]

So the nth term is [tex]a_n=\frac{1}{8} (2^{n-1})[/tex]

Answer:

Step-by-step explanation:

1.  12/3x = 1/2

4/1x = 1/2

4/1x = 1/2 / 4/1

1/2 x 1/4 ,  x = 1/8.

2).    x / 2.5 = 1. 75/ 1

cross multiply to get

x = 2.5 x 1.75

x = 4.375

Answer:

8th Person = 172 cm tall

Step-by-step explanation:

( a + b + c + d + e + f + g )/7 = 156

a + b + c + d + e + f + g = 1092 total size

----------------------------------------------------------

now they measured 8 people (a + b... g) + h, but we know the total size of the other 7 = 1092

a + b + c + d + e + f + g + h

( 1092 + h )/8 = 158

1092 + h = 158*8

h =  1264 - 1092

h = 172

-----------------------------------

the 8th person is 172 cm tall

The circumference formula for a circle is C=πd where C is the circumference, d is the diameter of the circle and π is a constant. If you plug in 6 for C and solve the equation for d like:

6= πd and then divide both sides of the equation by π you get that d = 1.90

To find the central angle of an arc you would use the equation S = rθ where S is the length of the arc, r is the radius of the circle, and θ is the measure of the angle which in this case is unknown. So with S = 1 and r = d/2 = 1.90/2 = 0.9549 you would have an equation that looks like this:

1 = 0.9549θ

Answer:

60

Step-by-step explanation:

1/6 x 360

Central angle is equal to measure of intercepted arc.

About 2:18

With this information, we can make a hypothesis or come to a conclusion that the clock says 2:18

Answer:

Step-by-step explanation:

The picture does not show the example which will help in determining whether it is simple or compound interest calculation.

Based on what is shown, the answer is:

the numerator is: {(n + 11) + (n + 10) + (n + 9 ) + (n + 8) = 4n + 38;

and the denominator is: {(n) + (n + 1) + ... + (n + 11) = 12n + 66.

Therefore, the fraction is numerator/denominator:

= (4n + 38) / (12n + 66)

In this case n=1, the fraction = 42/78 =  0.53846

= 53.85%

Answer:

1/64

Step-by-step explanation:

The probability of both dice being a 1 is 1/8 * 1/8 = 1/64

Answer:

35 degrees

Step-by-step explanation:

Answer:

The measure of the angle is 35 degrees

Step-by-step explanation:

There are two measurements on the protractor.

If the angle is acute you will use the smaller measurenment of the two, and if the angle is obtuse, you will use the larger of the two.

In this case the angle is acute, so the measure is 35 degrees.

Answer:

9.42 cube.yd

Step-by-step explanation:

Volume of cylinder= πr^2h

Area = length x width

Half the perimeter = length + width

half the perimeter = 14 inches.

Find 2 numbers when added together = 14 and when multiplied together = 48

6 + 8 = 14

6 x 8 = 48

the dimensions are 6 inches by 8 inches

12 shade out of 15 boxes which gives 0.8 chance of picking a shaded one.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

There are 15 sections given

To make the probability of choosing a shaded section randomly 0.8,

So,

0.8 of 15

0.8 is equal to 80%

we need to figure out 80% of the 15

80% of 15

80% × 15

= 12

Hence, we would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one.

Answer:

B=5

Step-by-step explanation:

If 7 plus a equals 9 then a would equal 2.

2+8=b+5

10=b+5

Ask yourself what number plus 5 equals 10

B is 5 because 5 plus 5 is 10
