Sam's mother is twice as old as Sam. In 12 years, Sam will be as old as his mother was 12 years ago. How old are Sam and his mother now?

Answers

Answer:

Sam is 24 years old and his mother is 48 years old.

Step-by-step explanation:

Equations

Let's call

x   = Sam's current age

Since Sam's mother is twice as old as Sam:

2x = Sam's mother current age

x + 12 = Sam's age in 12 years

2x - 12 = Sam's mother age 12 years ago

These two last expressions are equal:

x + 12 = 2x - 12

Subtracting x and adding 12:

x = 24

2x = 48

Sam is 24 years old and his mother is 48 years old.

Sam, is 24 years old. His mom is 48 years old.

Step-by-step explanation:

Answer:

y = x+40

Step-by-step explanation:

First, calculate the rate of the rate by using the slope formula, [tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex].

m = (50-47)/(10-7) = 3/3 = 1

Now plug m = 1 into the slope-intercept form, y = mx+b. Also plugin y = 42 and x = 2 in other to find the y-intercept (b).

42 = 1(2)+b

42-2 = b

b = 40

Replace b with 40 in the slope-intercept formula.

y = x+40

$3 is what percent of $10?

Answers

30%, have an nice day. Brainliest please?

The value of $3 is 30% of the number $10.

The percentage is a way to express a proportion or a fraction as a fraction of 100. It is commonly used to compare values or quantities relative to a whole or a total.

The term "percentage" comes from the Latin word "per centum," which means "per hundred." It implies that a percentage value represents a certain number out of 100 parts.

To calculate a percentage, you typically divide a part or a quantity by the whole or the total and then multiply the result by 100. The resulting value represents the percentage equivalent of the part or quantity.

The per cent value is calculated as,

[tex]x = \dfrac{3} {10} \times100\\x = 0.3\times100\\x = 30 \%[/tex]

Therefore, the percentage value is 30%.

Part B - Find the measure of angle e showing all work and reasoning. (3 points)

Part C - Find the measure of angle f showing all work and reasoning. (3 points)

Part D - What does the box mean in the triangle with angles e and d? (1 point)

Answers

Answer:

Part A - Angle d is 29º

Part B - Angle e is 61º

Part C - Angle f is 95º

Part D - the box represents a 90º angle

Step-by-step explanation:

Angle d is 29º because of the vertical angles theorem

Angle e is 61º because if you take into account that it tells you one of the angles is 90º, you'll add d, which is 29º, to that in order to get 119. Then you'll subtract 119 from 180, as all the angles in a triangle must have a sum of 180º degrees. The result should be 61º

Although it looks rather acute, f should be 95 degrees because it's a supplementary angle with 85º, meaning you subtract 85 from 180

The box in the triangle is just a symbol indicating a 90º angle

You win an online auction for a toy. Your winning bid of $90 is 75% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?

Answers

75% = 75/100 = 0.75

Let your bid = b
b * 0.75 = 90

Divide by 0.75
90/0.75 = 120

Check:
120 * 0.75 = 90 :)

I could have paid $30 more dollars for the toy than I actually paid.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, You win an online auction for a toy and your winning bid of $90 is 75% of your maximum bid.

Assuming 'x' is the maximum amount I could have paid for the bid.

Therefore, 75% of 'x' is $90 which is,

(75/100)×x = 90.

0.75x = 90.

x = 90/0.75.

x = 120.

So, The amount of more money I could have actually paid is,

(120 - 90)

= $30.
