Alexton the Skeleton borrowed $4000 or 5 years
at a 6% simple interest rate to pay for his band
equipment. How much interest is that?
Answer: $1,200
Step-by-step explanation:
If you use the simple interest formula, I = (p)(r)(t), you’ll replace it with I = 4,000 x 0.06 x 5 it’ll give you $1,200 :)
Given P(A) 0.3, P(B) = 0.43 and P(ANB) = 0.249, find the value of
P(AUB), rounding to the nearest thousandth, if necessary.
Answer:
0.481
Step-by-step explanation:
P(A U B) = P(A) + P(B) - P(A∩B)
= 0.3 + 0.43 - 0.249
= 0.73 - 0.249
= 0.481
Isaac has three types of coins in his pocket. There are two more quarters than dimes, and as many nickels as quarters and dimes together. The coins total $3.75. How many quarters, dimes, and nickels are in Isaac's pocket?
Answer:
There are 16 nickels, 7 dimes, and 9 quarters.
Step-by-step explanation:
Aight, so lets set dimes as "x". Since there are 2 more quarters than dimes, quarters is "x+2". And since nickels is equal to dimes plus quarters, nickels takes the role of "(x+2)+x". We can simplify this by adding x and x together, so nickels is "2x+2" In this example, I'm converting these variables to cents, since it's easier than converting to dollars. Since a dime is 10 cents, 10 times x is"10x". Quarters are worth 25, so first we do x times 25 (25x) and then 2 times 25 (50). Then nickels. 2x+2 times 5 is 10x + 10. Alright, so now we have our cent values. $3.75 is 375 cents, so now we can make an equation:
10x + 25x + 50 + 10x + 10 = 375 cents.
I'm guessing you already know how to solve an equation, first combine like terms, then figure out how many times the variable goes into the numerical value. You should end up with 7, which is dimes. If we go back to our problem, we see that there are 2 more quarters, so 7+2= 9 quarters. As for nickels (9+7) there are 16 nickels.
There's probably a more efficient way to do this, but since I'm so... uh... inefficient, this is the best explanation I can do :p
Answer:
16 nickels 7 dimes 9 quarters

3m + 2n + 4;
m = 2 and N =4
D2 + 9k; d = 10 and k =9
3m + 4y x 2 m = 7, y = 10
Answer:
1. 18
2. 181
3. 101
Step-by-step explanation:
They want you to take each equation, and replace the letter with the number they give you after the equation.
3m + 2n + 4; m = 2, n = 4
This becomes
3(2) + 2(4) + 4
We multiply before we add, according to the order of operations. So next, the equation becomes:
6 + 8 + 4
= 18
———-
D^2 + 9k ; D = 10, k = 9
Numbers squared are numbers multiplied by themselves.
(10)(10) + 9(9)
= 100 + 81 = 181
——————-
3m + 4y x 2 ; m = 7, y = 10
3(7) + 4(10) x 2
21 + 40 x 2
Remember, multiplication always comes before addition.
21 + 80 = 101
Please let me know if you have questions on this.
A. Their rates of change differ by 2. B. Their rates of change differ by 4. C. Function M has a greater rate of change than Function P. D. Function M and Function P have the same rate of change.
Answer:
(a) Their rates of change differ by 2
Step-by-step explanation:
Given
See attachment for functions M and P
Required
Determine what is true about the rates of M and P
First, we calculate the slope (i.e. rate) of both functions.
Slope is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
From the table of M, we have:
[tex](x_1,y_1) = (-2,-9)[/tex]
[tex](x_2,y_2) = (2,11)[/tex]
So, the slope is:
[tex]m_M = \frac{11 --9}{2--2}[/tex]
[tex]m_M = \frac{20}{4}[/tex]
[tex]m_M = 5[/tex]
For function P, we have:
[tex]y = 7x + 9[/tex]
A function is represented as:
[tex]y = mx + b[/tex]
Where:
[tex]m = slope[/tex]
So, by comparison:
[tex]m_P = 7[/tex]
At this point, we have:
[tex]m_M = 5[/tex] --- Slope of M
[tex]m_P = 7[/tex] --- Slope of P
Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2
Other options are not true

Hello, can you please help me solve for the y intercept?
Answer:
The y-intercept is when the X is 0 And the y is whatever number it is. So in order to do that we need to find the pattern first and to do that we need to find the slope.
The slope here is 2/ 2 or 1.
So you add 1 to each side to find the next ordered pairs.
-5, -7
-4, -6
-3, -5
-2, -4
-1, -3
0, -2
So the y-intercept is -2.
The mean age of 5 people in a room is 33 years. A person enters the room. The mean age is now 37. What is the age of the person who entered the room?
Mean is the average,
The total ages with 5 people would be 5 x 33 = 165
the total ages with the 6th person is 6 x 37 = 222
The age of the 6th person is 222 - 165 = 57 years old.

a dress is regulary price a $45 thedress is marked down 30 percent what is sale price of the dress
Answer:
$31.50
Step-by-step explanation:
So first thing, it's necessary to figure out what 30% of 45 is.
You can set this up as an algebraic expression or your can multiple 45 by 3/10 to find out what that 30% is.
The algebraic expression would be 30% of 45 is x.
Using one of these two options; we would discover that 30% of 45 is 13.5.
However, this is not the answer, yet.
The question is looking for the price of the dress after the 13.5 is taken away.
Therefore, you would subtract.
45 - 13.5 = 31.5
Sooooo... your answer is "The sale price of the dress is $31.50."

My little brother spent $5 on comic books and magazines. He bought 4 items. If comic books
cost $1 and magazines cost $2, how many of each item did my brother buy?
comic books
magazines
No links please!
Thank you
Answer: He bought 1 magazine and 3 comic books.
Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.
CITY |. Temperature (°F) St. Louis | 32 Montreal |. -18 Buffalo. | -8 Orlando. |. 68 Juneau. |. -26 By noon, the temperature In Buffalo had risen by 14 °F. What was the temperature there at noon? How much higher was the 6 a.M. Temperature in St. Louis than Juneau?
Answer:
6°F
58°F
Step-by-step explanation:
From the data Given :
Temperature rise in Buffalo by noon time = 14°F
The initial temperature at Buffalo = - 8°F
Rise in temperature = 14°F
Therefore, temperature at noon = (-8 + 14)°F = 6°F
B.)
Temperature at 6am in St. Louis = 32°F
Temperature at 6am in Juneau = - 26°F
Temperature difference :
(32 - (-26))°F
32 + 26
= 58°F
Temperature in St. Louis is 58°F higher
