Step-by-step explanation:
You deposit $750 in an account that earns 7.5% simple interest. How much will be in the account after 5 years?
Answer:
$1,031.25 will be in the account
Answer:
$1031.25.
Step-by-step explanation:
The formula for simple interest is
I = PRT/100 so substituting:
I = 750 * 7.5 * 5 / 100
Interest I = $281.25.
Amount in account = 750 + 281.25
= $1031.25.

What is the length of NP?
A. 2 cm
B, 3 cm
C: 3.5 cm
D, 4.5 cm
E, 5 cm
Answer:
E.) 5 cm
Step-by-step explanation:
The shapes are congruent and are the same size, side TU is the same as NP. If TU is 5, then NP is 5.
Answer:
E. 5 cm.
Step-by-step explanation:
As the 2 figures are congruent then corresponding sides are congruent.
NP corresponds to UT = 5 cm.
So NP is 5cm long.
(If we rotate Figure 2 through 180 degrees anticlockwise we see that it fits exactly on to figure 1.)
Which quadratic function only has one x-intercept?
A f ( x ) = x 2 − 12 x + 36
B f ( x ) = x 2 − 13 x + 36
C f ( x ) = x 2 + 13 x + 36
D f ( x ) = x 2 + 20 x + 36
Answer:
f(x) = x² - 12x + 36 = (x - 6)²
The correct answer is A.
The quadratic function that has only one \(x\)-intercept is A. [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]
A quadratic function has only one [tex]\(x\)[/tex]-intercept if it touches the [tex]\(x\)[/tex]-axis at exactly one point, which happens when the discriminant [tex](\(\Delta\))[/tex] of the quadratic equation is zero. The discriminant of a quadratic function [tex]\(ax^2 + bx + c = 0\)[/tex] is given by:
[tex]\[ \Delta = b^2 - 4ac \][/tex]
Let's calculate the discriminant for each given function to determine which one has only one [tex]\(x\)[/tex]-intercept.
Option A: [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]
[tex]\[ a = 1, \, b = -12, \, c = 36 \][/tex]
[tex]\[ \Delta = (-12)^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 144 - 144 \][/tex]
[tex]\[ \Delta = 0 \][/tex]
Option B: [tex]\( f(x) = x^2 - 13x + 36 \)[/tex]
[tex]\[ a = 1, \, b = -13, \, c = 36 \][/tex]
[tex]\[ \Delta = (-13)^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 169 - 144 \][/tex]
[tex]\[ \Delta = 25 \][/tex]
Option C: [tex]\( f(x) = x^2 + 13x + 36 \)[/tex]
[tex]\[ a = 1, \, b = 13, \, c = 36 \][/tex]
[tex]\[ \Delta = 13^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 169 - 144 \][/tex]
[tex]\[ \Delta = 25 \][/tex]
Option D: [tex]\( f(x) = x^2 + 20x + 36 \)[/tex]
[tex]\[ a = 1, \, b = 20, \, c = 36 \][/tex]
[tex]\[ \Delta = 20^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 400 - 144 \][/tex]
[tex]\[ \Delta = 256 \][/tex]
Only option A has a discriminant of 0, which means it has exactly one \(x\)-intercept.
d) Calculate the area of a circle with a circumference of 31.4 in.
Answer:
A ≈ 78.54
Step-by-step explanation:
Area of a circle is A=πr^2
Since you do not know r (radius) you take the formula for the circumference of a circle (C=2πr), plug in 31.4 for C, and solve for r
Now that you have the radius of 4.99746521, you round it up to 5 and solve the area formula with 5 in as r.
answer:78.5

Jackson wants to divide a pound box of
trail mix into small bags. Each of the bags
will hold pound of trail mix. How many
bags of trail mix can Jackson fill?
Jackson can fill 2 bags of trail mix, with each bag holding ½ pound of trail mix.
To calculate how many bags of trail mix Jackson can fill:
First, determine how many bags can be filled with 1 pound of trail mix:
1 pound bag ÷ ½ pound per bag = 2 bags
Next, divide the pound box into bags: 1 pound box ÷ ½ pound per bag = 2 bags
Therefore, Jackson can fill 2 bags of trail mix.

C. You filled your car tank with gas at the beginning of the trip. At the start of
the trip, your odometer read 25,678 miles. At the end of your trip, your
odometer read 26,109 miles. When you filled your tank at the end of the trip,
it took 15 gallons of gas. How many miles per gallon did the car get?
Answer:
164
Step-by-step explanation:
To find the car's miles per gallon, divide the total miles traveled by the total gallons of gas used. In this case, the car got approximately 28.73 miles per gallon.
Explanation:To find the miles per gallon the car got, you need to divide the total miles traveled by the total gallons of gas used. In this case, the car traveled 26,109 - 25,678 = 431 miles and used 15 gallons of gas. Using the formula MPG = Miles / Gallons, we get MPG = 431 / 15 = 28.73 miles per gallon. Therefore, the car got approximately 28.73 miles per gallon.

An aircraft flies against the wind for a distance of 300 miles in 2 hours then the aircraft makes the return trip with the wind in 1 hour what was the aircraft average speed for the entire trip
The aircraft's average speed for the entire trip, both against and with the wind, is 200 miles per hour. This is calculated by dividing the total distance travelled (600 miles) by the total time taken (3 hours).
Explanation:To solve this problem, we'll use the formula for average speed: Total Distance/Total Time. In this case, the aircraft flies 300 miles against the wind and 300 miles with the wind, so the total distance is 600 miles (300+300).
The total time is the time it takes to fly against the wind plus the time it takes to fly with the wind, which is 3 hours (2+1).
So, the average speed for the entire trip is 600 miles/3 hours = 200 miles per hour.

-3(y+3)=2y+3
what’s the answerrr is there even a solution???
Answer:
y = -2 2/5
Step-by-step explanation:
-3(y+3)=2y+3
-3y - 9 = 2y + 3
-3y - 2y = 3 + 9
-5y = 12
y = 12/-5 = -12/5 = - 2 2/5
-3(y+3)=2y+3
Mutiply the bracket by -3
(-3)(y)= -3y
(-3)(3)= -9
-3y-9= 2y+3
Move -9 to the other side
Sign changes from -9 to +9
-3y-9+9= 2y+3+9
-3y= 2y+3+9
-3y= 2y+12
Move 2y to the other side
Sign changes from +2y to -2y
-3y-2y= 2y-2y+12
-3y-2y=12
-5y= 12
Divide both sides by -5
-5y/-5= 12/-5
Answer:
y= -12/5 or y=- 2 2/5

A model for my number has
6 ones blocks, 2 hundreds blocks, and 3 tens
blocks. What number am I
Answer:
A model for my number has 6 ones blocks, 2 hundreds blocks, and 3 tens blocks. The model number is 236.
Solution:
Given that the model has 6 ones blocks, 2 hundreds blocks, and 3 tens blocks. The model number can be found out by,
[tex]\bold{\begin{array}{l}{=\text { (number of hundreds block } \times 100)+(\text { number of tens block } \times 10)+} \\ {\text { (number of ones block } \times 1)}\end{array}}[/tex]
Given that number of one blocks = 6 blocks. Hence we get [tex]6 \times 1=6[/tex]
Number of ten blocks = 3.Hence we get [tex]3 \times 10 = 30[/tex]
Number of hundred blocks = 2 .Hence we get [tex]2 \times 100=200[/tex]
So the model number = 6 + 30 + 200
=236
Hence the model number is 236.

A plumbing company charges $50 for the first hour of a service call and $30 per hour for each hour or part of an hour that a job requires after the first hour. If the Smiths’ bill included $65 for supplies and the plumber worked 2 hours and 35 minutes, how much was their bill?
Answer:
$175?
Step-by-step explanation:
You know that the first hour is $50, and the second hour and the 35 minutes are $30 each, making it $60.
Add $60+$50= $110. Then add the parts cost, which is 65, and get $175

The percentage of the business that is owned by the five other partners is 87.5%.
Amount invested by Kyle = $20000
Total investment of the partners = $160000
The percentage of the business that is owned by the five other partners will be:
= ($160000 - $20000) / $160000 × 100
= $140000/$160000 × 100
= 87.5%
Therefore, the other partners have 87.5% of the investment.
