Caleb makes a deposit of $25 in his checking account. His balance after the deposit is $0. He uses a number line to represent the amount of his deposit and his balance before the deposit. Where would the two points be located on the number line? Plot the points on the number line.
Solution :
In the context, it is given that Caleb deposits some amount of money in his checking account. And after the deposit he is having no money in his account i.e. $0 as balance in his account. So he must be his balance as negative in his checking account. Accordingly, before deposit, Caleb had a balance amount of -$25 in his checking account. He deposited $25 to his account, so after the deposit, his balance in the account is $0.
Caleb uses a number line to represent his deposit and the balance before the deposit made.

Susie is solving the quadratic
Answer:
Option (D)
Step-by-step explanation:
Standard equation of a quadratic function is,
ax² + bx + c
Comparing this function with the given quadratic function,
f(x) = 2x² - 4x - 3
a = 2, b = -4 and c = -3
By using quadratic formula to get the value of x,
x = [tex]\frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
= [tex]\frac{-(-4)\pm \sqrt{(-4)^2-4(2)(-3)} }{2(2)}[/tex]
= [tex]\frac{4\pm\sqrt{16+24}}{4}[/tex]
= [tex]\frac{-4\pm \sqrt{40}}{4}[/tex]
= [tex]\frac{-2\pm \sqrt{10}}{2}[/tex]
Therefore, Susie made a mistake in step IV.
Option (D) is the answer.

Write the following expression in radical form
(8x)1/2= √
Write the following expression in exponential form.
√19 =
Answer:
See below
Step-by-step explanation:
Write the following expression in radical form
(8x)¹/² = [tex]\sqrt{8x}[/tex]Write the following expression in exponential form.
[tex]\sqrt{19}[/tex] = 19¹/²The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side.The third side is 7 meters more than the first side. What is the length of each side?
Answer:
The length of each side of triangle is:
First side of triangle = 21 inches
Second side of triangle = 16 inches
Third side of triangle = 28 inches
Step-by-step explanation:
Perimeter of triangle = 65 meters
Let
First side of triangle = x
Second side of triangle = x-5 (The second side is 5 meters less than the first side.)
Third side of triangle = x+7 (The third side is 7 meters more than the first side.)
We need to find length of each side.
The formula used is:
[tex]\mathbf{Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle}[/tex]
Putting values and finding value of x
[tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\65=x+x-5+x+7\\65=3x+2\\Switching\:sides\\3x+2=65\\Subtracting\:2\:from\:both\:sides\\3x+2-2=65-2\\3x=65-2\\3x=63\\Divide\:both\:sides\:by\:x\\\frac{3x}{3}=\frac{63}{3}\\x=21[/tex]
So, We get value of x = 21
Now, finding the length of each side of triangle:
First side of triangle = x = 21
Second side of triangle = x-5 =21-5 =16
Third side of triangle = x+7 = 21+ 7 = 28
The length of each side of triangle is:
First side of triangle = 21 inches
Second side of triangle = 16 inches
Third side of triangle = 28 inches

The club sold shirts and capes to raise money for new stage equipment. The club sold each shirt for $20.00. The club made profit of $4.00 for each shirt. Sold. Part A: The drama club sold a total of $480.00 worth of shirts. How much profit did the club make from the shirt sale?
Answer:
The club made a profit of $96 from the shirt sale.
Step-by-step explanation:
First, you have to find the number of shirts sold by dividing the total amount sold by the price per shirt:
480/20=24
Now, that you know the number of shirts that were sold, you can multiply the profit per shirt for the number of shirts sold:
4*24=96
According to this, the answer is that the club made a profit of $96 from the shirt sale.

Write the unit fraction depicted in the model as a percent.
One-fourth
Answer:
As
1/4×100 = 0.25×100
= 25%
Thus,
1/4 = 25%
Step-by-step explanation:
Given the fraction
1/4
In order to write the fraction 1/4 as a percent, all we need is to multiply 1/4 by 100.i.e.
1/4×100 = 0.25×100
= 25%
Therefore, we conclude that:
1/4 = 25%
