Suppose that a new employee starts working at $7.72 per hour and receives a 5% raise each year. After time t, in years, his hourly wage is given by the equation y=$7.72(1.05)t. Find the amount of time after which he will be earning $10.00 per hour.
After what amount of time will the employee be earning $10.00 per hour?
Answer:
substitute 10 for y (y=10) and solve for t
2.17
Step-by-step explanation:
I think the equation is written wrong because assuming that his wage increases at the end of each year, the beginning of the first year wages should be 7.72, not 0.
recommended correction
y=7.72 + (1.05)t

Divide 750 into the ratio 2:3
Answer:
300 : 450
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 = 5 parts
Divide 750 by 5 to find the value of one part of the ratio
750 ÷ 5 = 150 ← value of 1 part of the ratio , then
2 parts = 2 × 150 = 300
3 parts = 3 × 150 = 450
Then 750 in the ratio 2 : 3 = 300 : 450
The required answer is 750 in the ratio 2 : 3 = 300 : 450.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have to divide 750 into the ratio 2:3
The ratio is given in the question
⇒ 2:3
We can see that the sum of the parts of the given ratio as
⇒ 2 + 3 = 5 parts
Divide 750 by 5 to determine the value of one part of the ratio
So the value of 1st part of the ratio
⇒ 750 ÷ 5 = 150
Now, 2nd parts = 2 × 150 = 300
And, 3rd parts = 3 × 150 = 450
So, 750 in the ratio 2 : 3 = 300 : 450
Therefore, the required answer is 750 in the ratio 2 : 3 = 300 : 450.

electricity when they're on.
a. Jessica's parents estimate that she leaves the lights on unnecessarily for 2.5 hours per day. How many watt-hours of electricity are used by these bulbs during 2.5
hours?
b. Approximately how many kilowatt-hours of electricity are used in a year to keep these bulbs lit for 2.5 hours per day?
C. At a cost of $0.12 per kilowatt-hour, how much money is wasted per year by keeping these lights on unnecessarily? Round to the nearest dollar.

Jose is trying to pick out an outfit for the first day of school. He can choose from 2 pairs of pants, 6 t-shirts, and 3 pairs of shoes. How many different outfits does Jose have to choose from?
Jose has to choose from 36 different ways.
What is the Combination?The various ways in which objects from a set may be selected, generally without replacement to form subsets is known as combination.
For the given situation,
Pairs of pants = [tex]2[/tex]
T-shirts = [tex]6[/tex]
Pairs of shoes = [tex]3[/tex]
The formula to find the number of ways using combination = [tex]nC_{r}[/tex]
Number of ways of picking the outfit = [tex](2C_{1}) (6C_{1}) (3C_{1} )[/tex]
⇒ [tex](2)(6)(3)[/tex]
⇒ [tex]36[/tex]
Hence we can conclude that Jose has to choose from 36 different ways.

Step-by-step explanation:
opposite angles of the parallelogram are equal(or congruent):
4x+36=6x-2
6x-4x=36+2
2x=38
x=38/2=19
the sum of the angles of the parallelogram =360
4x+36=4(19)+36=112 angle P
6x-2=6(19)-2=112 angle M
let Q= N=x
2x+112+112=360

What is the perimeter of a quadrilateral with vertices at (5,2),
(10,2), (5,5), and (10,5)? PLZZ SHOW WORK AND RIGHT!
Answer:
16
Step-by-step explanation:
Draw a picture!
Length1 goes from (5, 2) to (10, 2)
since the y coordinate is the same
L1 = (10 - 5) = 5
Length2 goes from (5, 5) to (10, 5)
since the y coordinate is the same
L2 = (10 - 5) = 5
Width1 goes from (5, 2) to (5, 5)
since the x coordinate is the same
W1 = (5 - 2) = 3
Width2 goes from (10, 2) to (10, 5)
since the x coordinate is the same
W2 = (5 - 2) = 3
-----------------------
Perimeter
p = 5 + 5 + 3 + 3
p = 16
The perimeter of quadrilateral is 16 units.
What is quadrilateral?A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilateral interior angle sums are always equal to 360 degrees.
Given coordinates,
(5,2), (10,2), (5,5), and (10,5)
let A, B, C, and D be the points of coordinates (5,2), (10,2), (5,5), and (10,5) respectively.
Length1 goes from (5, 2) to (10, 2)
since the y coordinate is the same
AB = (10 - 5) = 5
Length2 goes from (5, 5) to (10, 5)
since the y coordinate is the same
BC = (10 - 5) = 5
Width1 goes from (5, 2) to (5, 5)
since the x coordinate is the same
CD = (5 - 2) = 3
Width2 goes from (10, 2) to (10, 5)
since the x coordinate is the same
DA = (5 - 2) = 3
perimeter = sum of all sides
p = 5 + 5 + 3 + 3 = 16 units
Hence the perimeter is 16 units.
