3. What is the simple interest and the amount in the account if you invested$175.00 for 90 days at 8%?
The formula for the simple interest I after an amount P is invested for period t at a simple interest rate r is:
[tex]I=P\cdot r\cdot t[/tex]In this problem, the simple interest annual rate is 8% = 0.08. But the period t of the investment is
t = 90 days = 3 months = (12/4) months = (1/4) year
And the rate is:
[tex]r=\frac{0.08}{\text{year}}=\frac{\frac{0.08}{4}}{\frac{\text{year}}{4}}=\frac{0.02}{t}[/tex]Then, using P = 175, the interest, in dollars, is:

Steps for graphing a quadratic equation from vortex form
Graphing a Quadratic Equation
Let's take as an example the function:
[tex]y=-2\mleft(x-3\mright)^2+5[/tex]The vertex form of a quadratic function is:
[tex]y=a\mleft(x-h\mright)^2+k[/tex]Where a is the leading coefficient and (h,k) is the vertex.
If a is positive, the function is concave up, if negative the function is concave down.
The first step is to obtain the parameters by comparing the given equation with the general equation.
Thus, we have: a = -2. Vertex = (3,5)
Now we locate the vertex in the coordinate plane and draw the parabola opening down.
For more precision, we can substitute some points around the vertex, like for example:
x={1,2,4,5}
We get the y-coordinates:
y={-3,3,3,-3}
Then we plot the graph as follows:

14% of what number is 21
Answer:
150 is the number
Step-by-step explanation:
The equation we should set up is from the sentence "14% of what number is 21"
To rearrange it into a proper equation, replace "of what number" with " * x "
and "is" with "="
The sentence becomes:
14% * x = 21
since 14% = 0.14, replace 14% with 0.14 in the equation
0.14 * x = 21
divide both sides by 0.14
x = 21 / 0.14
x = 150

A line is uniquely defined by two points. So, we only need to find two points that lie on the line.
[tex]x=1 \implies y=4(1)-1=3\\\\x=2 \implies y=4(2)-1=7[/tex]
So, you can draw the line through (1, 3) and (2, 7).
4Use algebra to solve the following equation. Round decimal to two places.400 (1.065)t = 850
We need to solve the equation
[tex]400(1.065)t=850[/tex]In order to do so, we can first divide both sides of the equation by 400:
[tex]\begin{gathered} \frac{400}{400}(1.065)t=\frac{850}{400} \\ \\ (1.065)t=2.125 \end{gathered}[/tex]Now, to isolate the variable t on the left side and find its value, we can divide both sides by 1.065:
[tex]\begin{gathered} \frac{\mleft(1.065\mright)}{1.065}t=\frac{2.125}{1.065} \\ \\ t=1.9953\ldots \\ \\ t\cong2.00 \end{gathered}[/tex]Therefore, rounding to two decimal places, the answer is 2.00.
Ben needs to buy so he can buy a package of three bars of soap for $3.75 or a package of eight bars of soap for $12. If he buys the cheapest soap how much will he save per bar
When he buys the cheapest soap, the amount he save per bar is $0.25.
What is money?Money is anything that's used as a medium of exchange.
In this case, three bars of soap cost $3.75. Each bar will bre:
= $3.75 / 3
= $1.25
Also, a package of eight bars of soap for $12. Each bar will be:
= $12 / 8
= $1.5
The amount that will be saved will be the difference between the values above. This'll be:

(3y+11) ° = _____ °
10y ° = ______ °
(4x-22) ° = _____ °
(7x+4) ° = _____ °
Answer:
(3y + 11)° = 50°
10y° = 130°
(4x - 22)° = 50°
(7x + 4)° = 130°
Explanation:
First, find the value of the variable. Let's find y.
(3y + 11) + 10y = 180 (sum of adjacent angles on a straight line)
Simplify and solve the equation.
13y + 11 = 180
13y = 169
y = 13
Substitute y into the angle measures to find values.
3(13) + 11 = 50
10(13) = 130
Hence, (3y + 11)° = 50° and 10y° = 130°.
Next, find x.
(7x + 4) + (4x - 22) = 180 (sum of adjacent angles on a straight line)
Simplify and solve the equation.
11x - 18 = 180
11x = 198
x = 18
Substitute x into the angle measures to find values.
4(18) - 22 = 50
7(18) + 4 = 130
Hence, (4x - 22)° = 50° and (7x + 4)° = 130°.
Alternatively, you do not have to find x to find (4x - 22)° and (7x + 4)°.
4x - 22 = 3y + 11 = 50° (vertically opposite angles)
7x + 4 = 10y = 130° (vertically opposite angles)

If Mark bought a pen for $0.49, a box of pencils for $1.29, and a pad of paper for $0.98, then he had spend a total of $ 2.76, and if 10 ice cream cones were brought for $0.35 each, then the total amount paid is $3.5
As per the question statement, Mark bought a pen for $0.49, a box of pencils for $1.29, and a pad of paper for $0.98,
And the coach bought 10 ice cream cones for $0.35 each.
We are required to calculate the following:
(a) The total amount Mark had to pay
(b) The total amount the coach had to pay
Starting with part (a),
If Mark bought a pen for $0.49, a box of pencils for $1.29, and a pad of paper for $0.98, then the total amount he will have to pay will simply be the summation of the individual costs, that is, $[0.49 + 1.29 + 0.98] = $ 2.76.
Now solving part (b),
If the coach bought 10 ice cream cones for $0.35 each, then the total amount he/she will have to pay, will be a simple multiplication of the price of one ice cream, with the number of ice creams bought, that is,
$[0.35 * 10] =$3.5
