RIDDLE ME THIS Fresh and invigorated after completing her algebra homework, Mimi appeared at the living room door. She held a piece of paper covered in scribbled numbers, 'm's, 'd's, and equations. "Dad!" she announced. "Five years from now you'll be only double my age!" "Amazing!" Dad almost looked up from the TV, but knew she hadn't finished. "But five years ago, you were triple my age then!" "I suppose in another ten years we'll be the same age," Dad grunted, changing channels. How old is Mimi? Hint Don't pay any attention to Dad's rather mindless comment at the end! He'd had a tough day.
Answers
Answer:
Mimi is 15.
Step-by-step explanation:
Set up two equations, and solve by elimination.
2(m+5) = d+5
- 3(m-5) = d-5
_____________
2(m+5) - 3(m-5) = 10
2m + 10 - 3m + 15 = 10
-m + 25 = 10
-m = -15
m = 15
Plug this back in to get dad's age.
2(m+5) = d+5
2(15+5) = d + 5
2(20) = d + 5
40 = d + 5
d = 35

Option d. m>7 is the correct answer.
Given,
2m+5>19
or, 2m+5+(-5)>19+(-5) [adding both side with a negative number doesn't
change the inequality sign]
or, 2m>14
or, (2m/2)>(14/2) [also dividing both sides by a non-negative number doesn't change the inequality sign]
or, m>7.
Hence, m>7 is the correct answer to the given question.

A restaurant serves you a 16-fluid ounce glass of juice that is 30% ice. How many fluid ounces of juice do you actually get? Show all of your work
Answers
to solve how much ice there is you need to do 16 • .30, which would get you 4.8
Now you need to subtract 4.8 from 16, since the 4.8 is the amount of ice in the glass of juice.
So you would actually get 11.2 ounces of juice.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

What is a biased estimator?An estimate that deviates from the genuine population value is said to be biased. If the kind and extent of the bias are known, a biased sample may still be informative. When a sample's value matches the actual value of a population parameter, that is an unbiased estimator.

you are completely right please follow your heart <3
You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

x = 30°
Step-by-step explanation:
m∠ONK = 180° (straight angle)
∠ONM + ∠MNL + ∠LNK = 180° (supplementary angles)
105° + 45° + m∠LNK = 180° (substitution)
m∠LNK = 30° (algebra)
m∠LNK + m∠NLK + m∠LKN = 180° (sum of interior angles of a triangle)
30° + 90° + 2x = 180° (substitution, m∠NLK = 90° bc supplementary angles; other supp. angle is 90°)
120° + 2x = 180°
2x = 60°
x = 30°
After 1 year, $50,000 deposited in a savings account with simple interest had earned $2,500 in interest. What was the interest rate?
pls explain how as well if you don't mind
Answers
Answer:
5%
Step-by-step explanation:
The formula for calculating simple interest is:
Interest = Principal × Rate × Time
Where:
Interest is the amount of money earned as interest
Principal is the initial amount of money deposited
Rate is the interest rate (expressed as a decimal)
Time is the duration for which the money is invested or the time period over which interest is calculated
In this scenario, the principal amount is $50,000, and the interest earned is $2,500. The time period is given as 1 year.
We can rearrange the formula to solve for the rate:
Rate = Interest / (Principal × Time)
Plugging in the given values:
Rate = $2,500 / ($50,000 × 1)
The calculation simplifies to:
Rate = $2,500 / $50,000
Dividing $2,500 by $50,000 gives us the decimal value of the interest rate:
Rate = 0.05
To express the interest rate as a percentage, we multiply the decimal value by 100:
Rate = 0.05 × 100
Rate = 5%
Therefore, the interest rate for the savings account is 5%.
Answer:
Interest Rate = 5%
Step-by-step explanation:
Principal = $50, 000
Rate = ?
Time = 1 yr
S.I = PRT/100
2,500/1 = 50,000 × R × 1/100
50,000R = 2,500 × 100
50,000R = 250,000
50,000R/50,000 = 250,000/50,000
R = 5 %
