What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

I am between24 and 34.

You say my name when you count by twos from zero.

This means,

= 2

You say my name when you count by fives from zero.

This means,

= 5

So,

25 is the number.

Thus,

The number is 25.

Find the balance in the account: $1,600 principal earning 7%, compounded semi-annually, after 33 years

Answers

A principal invested for n number of years increases as the equation projects F = P * (1+ i) ^n where F is the future worth, p is the present worth or principal and i is the interest rate. substituting, F = $1600 * (1+ 0.07/2) ^33*2 equal to amount of future worth or balance of $15494.70

Answer:

$15,494.70

Step-by-step explanation:

Compounding twice year, 3.5% each, 66 times

result=$1,600*1.035^66 = $15,494.70

Peggy had four times as many quarters as nickels. She had $2.10 in all. How many nickels and how many quarters did she have?Which of the following equations could be used to solve the problem?

Answers

value of the coin times number of coins summed up equal total value
so since we have "$2.10 in all"...
0.05n + 0.25q = 2.10

and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n

0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem

if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10

multiply
0.05n + 1n = 2.10

add like terms
1.05n = 2.10

divide both sides by 1.05
n = 2.10/1.05 = 2

then plug that back into
q = 4n
so
q = 4(2) = 8

therefore you have
2 nickels
and
8 quarters

15pts awarded and brainliest will be chosen!!!!!The ideal length of a particular metal rod is 30.5 cm. The measured length may vary from the ideal length by at most 0.015 cm. What is the range of acceptable lengths for the rod?

Answers

Answer: OPTION B

Step-by-step explanation:

Let be "x" the acceptable lengths for the rod.

You know that the ideal length of the metal rod is 30.5 centimeters and the measured length may vary from the ideal length by at most 0.015 centimeters.

Therefore, knowing this, you can say that the acceptable lengths must be:

$30.5cm-0.015cm\leq x\n\n30.485\leq x$
