Answer:
compound interest would be,
1495.91
and simple interest would be,
1470
Step-by-step explanation:
compound interest would look like,
1200 x 1.045 x 1.045 x 1.045 x 1.045 x 1.045
and simple interest would look like,
1200 x 0.045 = 54 = 4.5%
54 x 5 = 270
1200 + 270 = 1470
What number, when divided by 6, is equivalent to 15?
n=90
n=5/2
n=4
n=15
Answer:
90
Step-by-step explanation:
15+15=30
3x30=90
Therefore, the answer to what divided by 6 equals 15 is 90. You can prove this by taking 90 and dividing it by 6, and you will see that the answer is 15. Tip: For future reference, when you are presented with a problem like "What divided by 6 equals 15?", all you have to do is multiply the two known numbers together.
Therefore, n=90 is your correct answer

What are exponential growth and decay?A rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay. Over time, exponential functions monitor constant growth. Examples from the actual world include radioactive decay, compound interest, and bacterial proliferation.
Given, You have 976 grams of a radioactive kind of rhodium.
The formula for the amount of a substance remaining after a certain amount of time given its half-life is:
N = N₀ *[tex](1/2)^{t / t_{1/2} }[/tex]
where:
N₀ is the initial amount of the substance
N is the amount of the substance remaining after time t
t₁/₂ is the half-life of the substance
In this problem, N₀ = 976 grams, t = 120 seconds, and t₁/₂ = 30 seconds. We can plug these values into the formula and solve for N:
N = 976 * (1/2)⁽¹²⁰/³⁰⁾
N = 976 * (1/2)⁴
N = 976 * 0.0625
N ≈ 61
Therefore, after 120 seconds, there will be approximately 61 grams of the radioactive rhodium remaining.

lara makes salad dressing by mixing 8
spoonfuls of oil and some vinegar. The tape
diagram shows the ratio of oil to vinegar.
Answer:
3:6
Step-by-step explanation:
8 ÷ 4 = 2
2 ÷ 1 = 2
6 ÷ 3 = 2
Answer:
1. 2:8
2. 1:4
3. 3:12
Step-by-step explanation:
There are 2 parts of oil for every one part of vinegar.
2+1=3
The ratio is made up of 3 total parts.
The part to whole ratio of oil to total is 2:1.
We are looking for an equivalent ratio that has 8 spoonfuls of oil.
If we have 4 times as much oil, we also need 4 times as much vinegar.
Also, we will have 4 times as much total dressing.
2x4=8

The algrebra itself is fine. The exclusions are not so good. The difficulty comes in the denominator. It factors into (2x)(x - 3). x cannot take on a value of 0 (that was pointed out and that is correct). The problem comes in the plus/minus 3. Plus 3 is correct. x - 3 will come 0 if x = 3. Nothing bad will happen if x = - 3
Answer: So the exclusions in the denominator should be modified to x = 3.
Answer:
The excluded values are x-values that make the denominator of the original expression zero, since [tex]\dfrac{a}{0}[/tex] is undefined.
[tex]x = -3[/tex] is not an excluded value since this x-value does not make the denominator zero.
[tex]x = -3[/tex] makes the numerator zero, but as [tex]\dfrac{0}{a}=0[/tex] it is not an excluded value.
Therefore, step 3 of her work should read:
[tex]\textsf{Finding excluded values}:x\neq 0\:\textsf{and}\:x\neq 3[/tex]

1. A toy company finds there is a linear relationship between p, the price they charge for a playground ball, and n(p), the number of balls they sell during a year. When they charge $3, they sell 8000 balls during the year. However, sales drop to 5200 balls when they charge $5 each.
a. Write an equation for the linear function n(p).
b. Use your function to determine the number of balls they can expect to sell during the year if they charge $6.50 for a ball.
Answer:
Below in bold.
Step-by-step explanation:
The general form of a linear function can be written as:
n(p) = kp + C where k and C are constants.
So substituting the given data:
8000 = 3k + C
5200 = 5k + C Subtract
2800 = -2k
k = -1400
and C = 8000 - 3(-1400) = 12200
a. So the equations is:
n(p) = -1400p + 12200
b.
For a charge p of $6.50;
n(p) = -1400*6.5 + 12200
= 3100 balls.

A
Yes
(Choice B)
B
No
Answer:
choice B- no
Step-by-step explanation:
We have been given that Nate has 100 bananas. He will eat 2 of them every day.
Let x represent number of days. So bananas eaten in x days would be .
Total number of bananas, y, left after x days would be
We know that two proportional quantities are in form , where, k is constant of proportionality.
Since our equation is not in form , therefore, number of bananas Nate has left is not proportional to the number of days that pass.

Which expression is equal to:
4b + 4c / z
a. 4(b + c) / z
b. 4b(4c / z)
c. 8bc / z
d. (b + c) ● (4+z)
(marking brainliest)
4(b + c) / z
Reason:
We factor 4 from 4b+4c to get 4(b+c). The z in the denominator stays where it is. This factoring is possible because of the distributive property.
This is why [tex]\frac{4b+4c}{z}[/tex] is the same as [tex]\frac{4(b+c)}{z}[/tex]
Side note: you should use parenthesis to write (4b+4c)/z, which indicates all of 4b+4c is over top the z. This is because 4b+4c/z might get mistaken for [tex]4b+\frac{4c}{z}[/tex]
