Annie spent 2.5 hours doing homework. She spent 1/3 of the time on her history project. She spent 3/5 of the remaining time solving math problems. After that, Annie spent all remaining time writing an essay. How much time did Annie spend writing the essay?
Step-by-step explanation:
2.5 hours = 150 min
1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover
3/5 of 100 min is 60 min (1 hour) = 40 min leftover
She spent 40 min writing her essay

A TV programme begins at 7:45 p.m. and ends 50 minutes later
At what time does it finish?
A TV programme begins at 7:45 p.m. and ends 50 minutes later.At 8:35 pm time it will finish.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that a TV programme begins at 7:45 p.m. and ends 50 minutes later.
Addition is one of the fundamental mathematical operations we utilize on a daily basis. We employ addition of numbers in a variety of contexts. Working with time or money, such as adding up bills and receipts, is one of the most frequent daily uses for adding numbers.
We have to apply the addition operation by splittiong the time as,
=7:45 p.m + 50 minute
=7:45 p.m + 15 minute + 35 minute
=8:00 pm + 35 minute
=8:35 pm
Thus, a TV programme begins at 7:45 p.m. and ends 50 minutes later.At 8:35 pm time it will finish.

5(2x - 5) + 10x = 75
Answer:
x = 5
Step-by-step explanation:
5(2x-5) +10x = 75
10x -25 +10x = 75
20x - 25 = 75
20x = 100
x = 5

Answer: A
Step-by-step explanation:
The scale is equal. There are 5 m's. Thats the same thing as 5 x m. Which the same thing as 5m. So yes, 5m = 50.
SYSTEMS OF EQUATIONS- How many solutions?
Sy = 5x + 12
y = 5x + 18
O one solution
O no solution
O many solutions
Answer:
No solutions
Step-by-step explanation:
They have the same slope(5), meaning that they are parallel. since they are parallel they will never touch, thus there are no solutions

In a survey of 3,500 people who owned a certain type of car,1,925 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: percent of the people surveyed that were satisfied with the car= 55%
Step-by-step explanation:
Step 1
Total Number of people in the survey who owned certain type of car = 3,500
Number of people that would buy that type of car again = people surveyed that were satisfied with the car= 1,925
Step 2
Percentage of people satisfied with the car= people surveyed that were satisfied with the car/Total Number of people in the survey who owned certain type of car x 100
=1925 / 3500 x 100
=0.55 x 100
=55%

i need to identify the slope and the y-intercept of the line with a given equation, the given equation is y = 1/2x +5 . i need to graph it aswell.
Answer:
y-intercept: 5
slope: 1/2
Step-by-step explanation:
The equation y=1/2x+5 is an example of y-intercept form(y=mx+b). This is where b represents the y-intercept and m represents the slope. I will not graph this for you but can explain it.
First plot the y-intercept on the graph. (0.5). Then use the slope to find the next point off of the y-intercept. So for example, the next point would be (2,6).
order these from least to greatest

An account with an initial deposit of 3,500 earns 7.25% annual interest, compounded continuously. How much will the account be worth after 30 years? Round to the nearest cent.
Answer: $28,575.05
Step-by-step explanation:
Formula: FV = (1+r/n)^nt
FV = future value of the deposit
P = principal or amount of money deposited
r = annual interest rate (in decimal form)
n = number of times compounded per year
t = time in years.
3,500(1+7.25%)^30=28,575.05468
Maria has purchased a basic stained glass kit for $100. She plans to make stained glass suncatchers and
sell them. She estimates that the materials for making each suncatcher will cost $13. Model this situation
with a rational function that gives the average cost of a stained glass suncatcher when the cost of the kit
is included in the calculation. Use the graph of the function to determine the minimum number of
suncatchers that brings the average cost below $22.50.
The minimum number of suncatchers that brings the average cost below
$22.50 is
Answer:
Step-by-step explanation:
fixed cost = 100
variable cost = 13
soooo....
cost = (13x + 100)/x
the questions wants to know when cost < 22.50
22.5 > (13x+100)/x
look at graph attached ;)
it looks to me like it's at 11
22.5 > (13(11) + 100) / 11
22.5 > 22.09
try 10
22.5 > (13(10) +100)/10
22.5 > 23 not true so yes.. 11 is when the cost goes below 22.50
Answer:
Y’all the correct answer is 10

The average age of three people running for election is 42. A fourth person joins the race and the average drops to 40. What is the fourth person's age?
Call the four people [tex]abc[/tex] and [tex]d[/tex].
We know:
[tex]\frac{a+b+c}{3}[/tex][tex]=42[/tex]
and
[tex]\frac{a+b+c+d}{4}[/tex][tex]=40[/tex]
Thus:
[tex]a + b + c = 126[/tex]
[tex]\frac{126+4}{4} = 40[/tex]
[tex]126 + d =160[/tex]
[tex]d = 34[/tex]
