square centimeters.
Answers
Answer:
35 cm squared
Step-by-step explanation:
Triangle area = bxh 2 = 5.75 x 8 / 2 = 23
Trapezium Area = a+b /2 x h = 8 + 4 /2 x 2 = 12
23 + 12 = 35
Hope that helped!!! k
Explanation:
Find the area of trapezoid:
A = (8 + 4)2/2 = (12 x 2)/2 = 24/2 = 12
Find the area of the triangle:
A = (8 x 5.75)/2 = 4 x 5.75 = 23
Find the area of the whole shape:
A (trapezoid) + A (triangle) = A (whole shape)
12 + 23 = 35 = A (whole shape)
The Nguyen family and the Reed family each used their sprinklers last summer. The Nguyen family's sprinkler was used for 15 hours. The Reed family's sprinkler was used for 25 hours. There was a combined total output of 1175L of water. What was the water output rate for each sprinkler if the sum of the two rates was 55L per hour? Nguyenfamily'ssprinkler:Lperhour Reedfamily'ssprinkler:Lperhour
Answers
Answer:
Nguyen family's sprinkler: 20 L per hour Reed family's sprinkler: 35 L per hourStep-by-step explanation:
Let n and r represent the output in liters per hour of the Nguyen and Reed family sprinklers, respectively. Then we have ...
15n +25r = 1175 . . . . total sprinkler output
n + r = 55 . . . . . . . . . sum of two output rates
The second equation tells us we can substitute n = 55 -r into the first equation:
15(55 -r) +25r = 1175
10r = 1175 -825 . . . . . . subtract 825
r = 350/10 = 35 . . . . . . divide by 10
n - 55 -35 = 20 . . . . . . find n from r
Nguyen family's sprinkler: 20 L per hour
Reed family's sprinkler: 35 L per hour

Answers
The combined radical is: [tex]- 26\sqrt{3}[/tex]
The radical is given as:
[tex]- 12\sqrt{12} - 2\sqrt{3}[/tex]
We start by expressing 12 as 4 * 3
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 12\sqrt{4* 3} - 2\sqrt{3}[/tex]
Split the radical
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 12\sqrt{4}* \sqrt{3} - 2\sqrt{3}[/tex]
Take square root of 4
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 12*2* \sqrt{3} - 2\sqrt{3}[/tex]
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 24* \sqrt{3} - 2\sqrt{3}[/tex]
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 24\sqrt{3} - 2\sqrt{3}[/tex]
Combine like terms

Geoffrey is trying to earn $50 to buy a video game. He has saved $14.25. He earns $3.75 per hour cleaning windows with his uncle and he earns $6.50 per hour working at the grocery store. Can Fred buy the video game if he works with his uncle for 3 hours and at the grocery store for 4 hours? Use the inequality 3.75y + 6.50z + 14.25 ≥ 50.
Yes, because the total will be $51.50.
Yes, because the total will be $60.25.
No, because the total will be $24.50.
No, because the total will be $37.25.
Answers
Answer:
yes the total will be 51.50
Step-by-step explanation:
3.75(3) + 6.50(4) + 14.25 [tex]\geq[/tex] 50.
11.25 + 26 + 14.25 = 51.50
Answer:
Yes, or A
Step-by-step explanation:
You can go onto a graphing calculator and input that inequality to find the solution, but you can multiply the 3.75 by 3 because he works with his uncle for 3 hours, and multiply the 6.5 by 4 to get 11.25 and 26. You add these together to get 37.25 and then add the 14.25 from his savings to get 51.50.
51.50 is how much he will have, and this is greater than 50.
Getaway Travel Agency surveyed a random sample of 45 4545 of their clients about their vacation plans. Of the clients surveyed, 21 2121 expected that they would go on 3 33 vacations in the next year. There are 516 516516 Getaway Travel Agency clients. Based on the data, what is the most reasonable estimate for the number of Getaway Travel Agency clients who expect to go on 3 33 vacations in the next year?
Answers
Answer:
241
Step-by-step explanation:
Given the following :
Number of random samples surveyed = 45
Of the random samples surveyed, 21 expected to go on 3 vacations in the next year:
Total number of clients = 516
Percentage of random sample surveyed who intend to go 3 vacations in the next year :
(21 / 45) * 100
0.4666667 * 100 = 46.7%
That is 46.7% of surveyed sample intend to go on 3 vacations in the next year.
Therefore using these to make inference about the number of total client who will go on 3 vacations in the next year:
46.7% of total clients
(46.7 / 100) * 516
= 240.8
= 241 ( to the nearest whole number)

A group of friends is addressing wedding invitations. Casey can address 22 envelopes in one hour, Anne can address 48 envelopes in two hours, and Paula can address 62 envelopes in three hours. About how long will it take them to address 420 envelopes?
A.
19.09 hours
B.
22.00 hours
C.
7.24 hours
D.
6.30 hours
Answers
Answer:
D
Step-by-step explanation:
Let's say that we have x amount of hours.
Casey addresses 22 envelopes per hour. Another way of writing this is that for x hours, Casey addresses 22 envelopes. Therefore, given x hours, Casey addresses 22 * x envelopes.
Anne can address 48 envelopes in 2 hours. It is important to note that this is for 2 hours. To make this per 1 hour, we can write
48 envelopes = 2 hours
divide both sides by 2
24 envelopes = 1 hour.
Therefore, given x hours, Anne addresses 24 * x envelopes.
Paula can address 62 envelopes in 3 hours, so
62 envelopes = 3 hours
divide both sides by 3
62/3 envelopes = 1 hour
Given x hours, Paula can address 62/3 * x envelopes.
Adding all of these up, given x hours, the group of friends can address
22 * x + 24 * x + 62/3 * x envelopes. Because the variables are all the same (x), we can add up the coefficients, resulting in
(22 + 24 + 62/3) * x = (46 + 62/3) * x envelopes given x hours
We want to figure out the amount of hours (x) for 420 envelopes. The total amount of envelopes is equal to (46 + 62/3) * x, so we set 420 equal to that, resulting in
(46 + 62/3) * x = 420
divide both sides by (46 + 62/3) to isolate x
420 / (46 + 62/3) = x
= 6.3 hours

Mr Hamar had rupees 4,400 hie purchase 6 kg of rice at Rupess 75 for KG ,2 packets of oil at rupees 125 per packet and he gave rupees 3,300 to his wife if he divided the remaining Sum between his son and daughter equally find the share of each of them
Answers
Step-by-step explanation:
Total rupees= 4400
Price of 6kg rice = 75 x 6 = 450
Price of 2 packets oil = 125 x 2 = 250
Amount given to wife = 3300
Total = 450 + 250 + 3300 = 4000
Remaining amount = 4400 - 4000 = 400
Share of son and daughter = 400 ÷ 2 = 200
So his son and daughter both get 200

A pyramid has a square base with an area of 169 ft.² what is the perimeter of the base of the pyramid
Answers
Answer:
52
Step-by-step explanation:
Square root of 169 is 13.
SInce it is a square all sides are same length. So you could do 13x4 or 13+13+13+13. Both will equal to 52.
The perimeter of the base of the pyramid is 52 square feet.
Given that,
The pyramid contains a square base having an area of 169 square feet.
We know that,
Area of the square = side^2
169 = side^2
So, the side is 13 feet.
So, the perimeter should be
= 4 × sides
= 4 × 13
= 52 feet
Therefore, we can conclude that The perimeter of the base of the pyramid is 52 square feet.

Victoria is scuba diving off the coast of Hawaii. When she is ready to come back to the surface, she rises 40 yards at a safe speed. She climbs 1 foot every 2 seconds. How many minutes will it take her to reach the surface?
Answers
Answer:
it will take her 79.76 minutes to rise to the surface
Step-by-step explanation:
Total distance to the surface = 40 yards
speed of rising = 1 foot per seconds
1 foot = 1 second
since the total distance is in yards, let's convert from foot to yards:
1 yard = 3 feet
1 foot = 1/3 yards = 0.333 yards
0.33 yards = 1 second
Next, let's convert from seconds to minutes
60 seconds = 1 minute
∴ 1 second = 1/60 minute
1 second = 0.0167 minute
Therefore the speed at which she rose:
speed
0.333 yards = 0.0167 minutes
Now for a distance of 40 yards:
[tex]1\ yard = \frac{0.0333}{0.0167} minutes\\\therefore\ 40\ yards = \frac{0.0333}{0.0167} \ \times\ \frac{40}{1} \\= \frac{1.332}{0.0167} \\= 79.76\ minutes[/tex]
