Answer:
20
Step-by-step explanation:
[tex]\frac{35n}{35} =\frac{700}{35} \\[/tex]
multiply both sides by 35
[tex]35*\frac{35n}{35} = 700 * 35\\35n = 700[/tex]
divide both sides by 35
[tex]n = 20[/tex]
Answer:
N = 20
Step-by-step explanation:
Move all terms to the left
35n/35-(700/35)=0
Add all of the numbers together, and all of the variables
35n/35-20=0
Multiply all of the terms by the denominator
35n-20*35=0
Add all of the numbers together, and all of the variables
35n-700=0
Move all of the terms containing N to the left, all other terms to the right
35n=700
n=700/35
n=20
You have one coupon for x dollars off and another coupon for x% off.
Write a rule that helps you decide when you should use one instead the other.
Answer:
if you want an item that is 100 dollars of then you would like the precent of because 1-100 percent is 1-100 so the larger the number the more you would want the percent but if it is 10% or 5 dollars of on an item of 10 dollars then the dollars of would be better so the higher the number the more you want percentage.

A sample contains 16.75 g of the radioisotope u-236 and 50.25 g of its daughter isotope, th-232. how long did it take for decay to take place if one half-life of u-236 is 23 million years? 46 million years 69 million years 92 million years 115 million years
If one half-life of U-236 is 23 million years then it will take 45.5 or approximately 46 million years to decay. Then the correct option is A.
What is half-life?Half-life is the time interval that is needed to decay the atomic nuclei of a radioactive sample.
A sample contains 16.75 g of the radioisotope U-236 and 50.25 g of its daughter isotope, Th-232.
Initially, the whole sample is consisting the radioisotope. Then the initial total mass will be
m₀ = 16.75 + 50.25
m₀ = 67 g
Now we also know that the half-life is 23 million years. Then we have
[tex]m = m_oe^{- \lambda t}[/tex]
Then put the value
[tex]\begin{aligned} 16.75 &= 67 e^{- \lambda t}\\\\0.254 &= e^{- \lambda t}\\\\\lambda t &= 1.37\\\\\dfrac{ln2}{23 \rm \ million \ years } \times t &= 1.37\\\\t &= 45.5 \ \rm million\ years \end{aligned}[/tex]
If one half-life of U-236 is 23 million years then it will take 45.5 or approximately 46 million years to decay. Then the correct option is A.

if two angles 2x+10°and 3x+20°are supplementary find x
Answer:
x = 30
Step-by-step explanation:
Supplementary angles sum to 180° , then
2x + 10 + 3x + 20 = 180 , that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
HELP ASAP A function is defined by fx) = 6x+1.5. What is f(2.5)?

Rachel took out a personal loan for $4,500 with a monthly payment of $173.06 for 36 months. determine the finance charge on rachel's loan if she takes all 36 months to pay it off. a. $48.06 b. $1,730.16 c. $4,500.00 d. $6,230.16
The finance charge on Rachel's loan if she takes all 36 months to pay it off is $1730.16.
The amount of personal loan = $4500
Monthly payment =$173
Loan tenure = 36 months
The total amount that Rachel will pay for 36 months = 36*173.06
The total amount that Rachel will pay for 36 months = $6230.16
What is the finance charge?A finance charge refers to any cost related to borrowing money, obtaining credit, or paying off loan obligations.
The finance charge on Rachel's loan if she takes all 36 months to pay it off = The total amount that Rachel will pay till 36 months - Amount of personal loan
The finance charge on Rachel's loan = 6230.16-4500 = $1730.16
Therefore, The finance charge on Rachel's loan if she takes all 36 months to pay it off is $1730.16.

A. Antonia has a green rope and a blue rope. Her green rope is 4 feet in length. She cut the green rope into 2 pieces. One of the pieces is 21 inches in length.
How many inches long is the other piece of the green rope? Use words and numbers to explain your reasoning.
B. Antonia's blue rope measures 2 yards. She wants to cut the rope into MORE than 3 pieces so all the pieces of rope are equal in length with no rope left over.
What is ONE possible way that Antonia can cut the rope so that each piece of rope is less than 24 inches in length? Use words and numbers to explain your reasoning.
Type your answer in the box below. Make sure to label each part with A and B.
Answer:
The other part is 27 in. long
Step-by-step explanation:
1 ft is 12 in
2 ft are 24 in
4 ft are 48 in
48 in - 21 in = 27 in
Answer:
Part A
Green rope = 4 ft
As 1 ft = 12 in
Then 4 ft = 4 × 12 in = 48 in
Antonia cuts the green rope into 2 pieces. One of the pieces is 21 in long. To find the length of the unknown piece, subtract the length of the known piece from the total length:
length of unknown piece = 48 - 21
= 27 in
Part B
Blue rope = 2 yd
1 yd = 36 in
Therefore, 2 yd = 2 × 36 = 72 in
Antonia wants to cut the rope into MORE than 3 pieces, and all the pieces need to be of equal length. As the length of the rope is an even number of inches, Antonia could first cut the rope in half, so she would have 2 pieces each of 36 in in length. Then she could cut both of those lengths in half, so she would have 4 pieces each of 18 in in length.

Step-by-step explanation:
looking at line CF,
it is a straight line thus being 180°
the < EOD is 90° < EOF is 55°
let < COD = t
therefore,
EOD + EOF + COD = 180
90 + 55 + t = 180
taking terms
t = 180 - (90 + 55)
t = 180 - 145
t = 35
COD = 35
EOD = 90
THUS, COE = COD + EOD
COE = 35 + 90
COE. = 125

Ms. Caswell deposits $450 into an account earning 8% simple interest per year. How
much simple interest is earned after 4 years?
Answer:
$144
Step-by-step explanation:
Use the simple interest formula, I = prt, where I is the interest money created, p is the starting amount, r is the interest rate as a decimal, and t is the amount of time.
Plug in the original amount, interest amount, and amount of time:
I = prt
I = 450(0.08)(4)
I = 144
So, $144 in simple interest is made in 4 years
