0.74.....so what place value is the last number in ? Because if u know that, this wont be hard to do. Its in the 100ths place....so put that number over 100 and reduce if possible.
74/100 reduces to 37/50.....and if u were to get a calculator and type in 37 divided by 50, ur gonna get 0.74.....and thats how to turn a fraction into a decimal (just in case u were interested)
Answer 2
37/50, as previously said find place value of last digit (100th) and put it over (74/100) find a number both can be divided by (2) and divide to reduce

How to solve a literal equation
Answers
To solve a literal equation, you need to plug the values that you have in to it.
Take the literal equation d=rt
If you are given the rate, r, and time, t, you can plug them in to the equation and solve for d
For example, say the rate is 5 mph and the time is 2 hours.
Put the two in and get d = 5*2, or d = 10.
The unit will depend on what you're solving for, but in this case the the answer is 10 miles.

Alli, Beth, Catie, Dave, Eddie, Franny, and George invested $4,914,000 in a business venture in the ratio of 1:2:3:4:5:6:7 respectively. How much did Alli and George each invest?
Answers
The amount did Ali and George invested is $175500 and $1228500
Calculation of the amount invested:
The total of the ratio is
= 1+2+3+4+5+6+7
=28
Now Divide the invested money by 28
So, it is =
=175500
Now
For Ali==175500
For George==1228500

Ali-175500
George-1228500
Explanation:
Add all the ratio numbers
1+2+3+4+5+6+7=28
Divide the invested money by 28
4914000/28=175500
Multiply that by the ratio of the person
Ali=175500*1=175500
George=175500*7=1228500

The piggybank had $25.65 in dimes and
quarters. If there were 20 more quarters
than dimes, how many dimes were in the
piggybank?
Answers
Answer:
Step-by-step explanation:
0.10d + 0.25q = 25.65
q = d + 20
0.10d + 0.25(d + 20) = 25.65
0.10d + 0.25d + 5 = 25.65
0.35d = 25.65 - 5
0.35d = 20.65
d = 20.65 / 0.35
d = 59

In a bag , there are 5 blue marbles, 3 red marbles and 2 green marbles. If there marbles are chosen consecutively at random without replacement, what is the probility that the color of the chosen marbles would be blue-red-green in that order?
Answers
First, you have a 5/10, or 1/2 chance of getting a blue.
Then, for red, it would be 3/9, or 1/3, because you already drew a marble out.
Finally, green would be 2/8, or 1/4, because by now you've already drawn out 2 marbles.
Multiply each of the chances: 1/2 * 1/3 * 1/4
The answer will be 1/24
Bryce took a quiz that consisted of true-or-false questions and multiple-choice questions. The true-or-false questions were worth 1 point each, and the multiple-choice questions were worth 2 points each. Bryce only knows that he answered 8 questions correctly and earned a total of 14 points. To determine the number of each type of question that he answered correctly, he wrote the system of linear equations x + y = 8 and x + 2 y = 14. NEED ASAP
Answers
Answer:
Step-by-step explanation:
x + 2y = 14
x + y = 8.....x = 8 - y
8 - y + 2y = 14
y + 8 = 14
y = 14 - 8
y = 6
x + y = 8
x + 6 = 8
x = 8 - 6
x = 2
solution : x = 2 and y = 6.....or (2,6)

Suppose that the heights of adult women are normally distributed with b = 65 inches and o= 2.5 inches. Find the probability that a randomly chosen woman is taller than 65 inches.
Answers
The probability of a randomly chosen woman taller than 65 inches is 0.5
Step-by-step explanation:
To find the probability of a random variable X which has a normal distribution do that
- If X > b, find the z-score using the formula z = (b - μ)/σ, where μ is the mean and σ is the standard deviation
- Use the normal distribution table of z to find the corresponding area to the right of z-score (Area to the right = 1 - area to the left)
∵ The heights of adult women are normally distributed with
μ = 65 inches
∵ σ = 2.5 inches
- We need to find the probability of the woman taller than 65 inches
∵ X > 65
∴ b = 65
- Find z-score
∵
- Use the normal distribution table to find the area corresponding to z
∵ The corresponding area of z = 0 is 0.5
- Area to the right = 1 - area to the left
∴ P(x > 65) = 1 - 0.5 = 0.5
The probability of a randomly chosen woman taller than 65 inches is 0.5

The perimeter of a rectangular pool 160 meters. The length of the pool is 20 meters more than it's width. Which equaction can be used ? a x+x+80=160 b 2x+(40+x)=160 c 2(x+x)+40=160 d 2(x+40+x)=160
Answers
It would be c) 2(x+x)+40=160
If x is the width, then x + 20 is the length.
The perimeter will be:
2(x + x + 20) = 160
If you just multiply out the 20, you get
2(x + x) + 40 = 160
