Answer:

father's age = 86

son's age = 48

Step-by-step explanation:

86-10=76

48-10=38

38*2 = 76

Answer:

Step-by-step explanation:

You can use your number sense to reason your way through this problem, or you can write equations for it. If the father is 38 years older than his son, and that makes him twice as old, the son must be 38 and the father 76. This was the condition 10 years ago, so their ages now are ...

__

If you prefer to solve a set of equations, you can assign variables f, s, to the father's age and the son's age respectively.

  f = s +38 . . . . . . the father is 38 years older than the son.

  (f -10) = 2(s -10) . . . . 10 years ago, the father was twice as old as the son

The first equation gives an expression we can use to substitute into the second equation:

  s +38 -10 = 2s -20 . . . . substitute for f, eliminate parentheses

  48 = s . . . . . . . . . . . add 20-s, collect terms

  f = 48 +38 = 86

The father is 86; the son is 48.

Additional comment

An age difference remains the same through the years. It is the same now as 10 years ago or 10 years in the future. A multiplying factor for ages gets smaller as years go by. Someone 3 times as old now will only be 2 times as old at some point in the future, for example.

The difference in ages is a multiple of the younger age that is 1 less than their ratio. In other words, if A is 3 times as old as B, the difference (A-B) is exactly (3 -1)×B = 2B. In the above problem, this was (f-s)=38; f/s=2, so we know 38 = (2 -1)s = s.

Answer:

Undercoverage Bias

Step-by-step explanation:

Undercoverage Bias occurs when some members of the population under study that should be included in the study are omitted. This then means that the sample is not a true representation of the entire population. In the sampling design above, a problem that would most likely occur would be undercoverage bias.

This is because the sample that was chosen for the study did not represent the entire population of the local households. Since they came during the daytime to conduct their poll, they have omitted members of the population who go to work and may not be at home at the time of the poll.

Step One, Find out the radius of the inner circle:

Circumference = 2πr

Circumference = 12.56

12.56 = 2πr

12.56/3.14 = 2r

4 = 2r

r = 2m

Step Two, Find out the radius of the entire circle:

2m + 3m = 5 m

Step Three, Find out the radius:

Area of circle = πr^2

Area of circle = 3.14 * 5^2

Area of circle = 3.14 * 25

Area of circle = 78.5 square meters

Answer:

the answer is 8 miles

Step-by-step explanation:

Answer:

Maybe It should be 8.

Step-by-step explanation:

Maybe 8 because if he walked only 2/3 of a mile than it can't be bigger than 12. If you understand what I'm saying. If he walks 12 miles from home to school than it can't be more than the number your starting with. Im not  actually sure that much but try it!

Answer:

22 shirts

Step-by-step explanation:

To find out how many shirts Ms. Li has in total, we have to set up a proportion.

As you can see, we multiply eight by two to get to sixteen. Whatever we do on the numerators, we must do to the denominators. Thus, eleven multiplied by two is twenty-two t-shirts.

Answer:

33 R 19.8

1.6 goes into 52.8, 33 times, so write 33 while including the tens place.

↓ Subtract 52.8 by 33. ↓

[tex]52.8-33=19.8[/tex]

Therefore, the answer is 33.

Answer:

Answer:

a2−b2=(a−b)(a+b).

Since a≥0 and b>0, a+b>0 and a−b<0 since a<b, thus: (a−b)(a+b)<0. So a2−b2<0. Thus a2<b2.

Answer:

a = 3, b = 3, c = 5 and d = 2.

Answer:

Hulain is 10 and Thomas is 5

Step-by-step explanation:

soooo

add variables

thomas age: t

hulians age: h

h = 2t

15 = t + 2t

umm i dont remember if you can add t and 2t they have the same um variable and power ig. if you can then:

15 = 3t

t = 5

sooo now hulians turn!

h = 2t

h = 2(5)

h = 10

Answer:

y = 1

Step-by-step explanation:

[tex]\frac{6}{2}=\frac{2(y+2)}{2}\\ \Leftrightarrow 3-2=y=2-2\\\Leftrightarrow y=1[/tex]

The solution to the given equation 6 = 2(y+2) is y = 1, which is determined by distribution and arithmetic operations.

The equation is given as follows:

6 = 2(y+2)

To solve the equation 6 = 2(y + 2) for y, we need to isolate y on one side of the equation.

First, distribute the 2 on the left side by multiplying it with y and 2:

6 = 2y + 4.

Next, move the constant term (4) to the other side of the equation by subtracting it from both sides:

6 - 4 = 2y

2 = 2y

y = 2/2

Apply division operation to get:

y = 1

Therefore, the solution to the given equation is y = 1.

#SPJ6

Answer:

Emily bought 1,836 inches of fabric.

Step-by-step explanation:

To figure this out we need the conversion factor of 1 yard = 36 inches.

So this will allow us to do simple multiplication which would look like this - 36 × 51.

When multiplied it ends up as 1,836 inches.

Hey there!

Use the slope formula:

[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]

[tex]\bold{\displaystyle\frac{0-0}{5-0} }[/tex]

[tex]\bold{\displaystyle\frac{0}{5} }[/tex]

[tex]\bold{0}[/tex]

There's an easier way to determine the slope.

As you can see, the y-coordinates of the points that the line passes through (0, 0) --> the origin and (5, 0).

This means the slope's 0.

Remember that

Hence, the slope's 0.

Hope everything is clear.
