A savings account earns 4.5% simple interest per year. If $650 is deposited and no withdrawals are made during one year, how much interest will be earned after one year?
Answer:
$29.25
Step-by-step explanation:
The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.

Simplify the expression
Answer: A
Step-by-step explanation:
Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.
First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical
[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]
The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.
[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]
The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

Answer:
43
Step-by-step explanation:
[tex]3^{3}[/tex]+[tex]4^{2}[/tex]=
Solve:
[tex]3^{3}[/tex]= 3*3*3= 9*3= 27
[tex]4^{2}[/tex]= 4*4= 16
Then add them together:
27+16= 43

Please someone help answer correctly !!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!
Answer:
z = 44
Step-by-step explanation:
180 - (44+52) = 180 - 96 = 84º
180 - 84 = 96º
180 - (96 + 40) = z
180 - 136 = z
z = 44
1) Walter opened a bank account with $0. He deposits $200 in the bank
each month. Write an expression that represents how much money
Walter has deposited after some number of months (m). Which
student below is correct? What mistake do the other students make?
Student A
200*10
Student B
2200
Student C
200m
Student D
m = 200
Answer:
Student C is correct.
Students A and B do not account for the variable in the equation. Student A assumes that it has already been 10 months when it has not been stated in the question. Student B has come to the conclusion that it has been 11 months. Neither have an equation to show for it. Student D is incorrect because the variable "m" equals the number of months, and the number of months would not equal the amount of money Walter would be receiving in total. Student C is correct because the variable "m", or months, is being multiplied by 200, or the amount of money.
For example, if 5 months were to pass, then you would receive 1000 dollars, because 5×200 is 1000. This would hold up, as in the original problem, you receive 200 dollars per month. another example is if you replace "m" with 0, then it will show that in 0 months, you will have 0 dollars, and it is stated at the beginning of the problem that Walter's bank account starts at $0.

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for
fencing. He knows that the area of the yard is 51 square meters and that the width is 5.2 meters longer
than the length. Which equation could be solved to determine the dimensions of the backyard, where the length
is / and the width is w?
0=w2+5.2w -51
o
0=12+5.21-51
4w + 10.4 = 51
о
41 +10.4 = 51
Answer:
The equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
Step-by-step explanation:
As given,
The backward is rectangular in shape
Also , we know that
Area of rectangle = 2 ( Length + Breadth )
Also, given,
Breadth of the backyard = 5.2 + Length of the backyard
Let
length of the backyard = l
Breadth of the backyard = w
∴ we get
w = 5.2 + l
⇒l = w - 5.2
and
Area = 2 ( l + w)
⇒51 = 2( w - 5.2 + w)
⇒51 = 2 ( 2w - 5.2)
⇒51 = 4w - 10.4
So, the equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
By solving we get
4w = 51 + 10.4
⇒4w = 61.4
⇒w = [tex]\frac{61.4}{4}[/tex] = 15.35
⇒ w = 15.35
⇒ l = w - 5.2 = 15.35 - 5.2 = 10.15
⇒l = 10.15
So the dimensions of the backyard = l × b = 10.15 m × 15.35 m

Solve the equation 3 (p-1) = 2p – 11.
Answer:
p = - 8
Step-by-step explanation:
3 (p - 1) = 2p - 11
3p - 3 = 2p - 11
3p - 2p = -11 + 3
p = -8
Answer:
p = - 8
Step-by-step explanation:
Given
3(p - 1) = 2p - 11 ← distribute parenthesis on left side
3p - 3 = 2p - 11 ( subtract 2p from both sides )
p - 3 = - 11 ( add 3 to both sides )
p = - 8

2. Solve x - 19 <81. Then graph the solution.
Answer:
x<100
Step-by-step explanation:
The given equation is :
x-19<81
Adding 19 to both sides of the equation.
x-19+19<81+19
x<100
It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.
