Glenn has 450 stamps that are red blue green. 52% are red. He has 3/5 as many green as blue stamps. How many are blue and how many are green.

In how many different ways can 3 identical green shirts and 3 identical red shirts be distributed among 6 children such that each child receives a shirt

Answers

Answer:

Total number of ways will be 20

Step-by-step explanation:

We have given three identical green shirts and three identical red shirts

So total number of shirts = 3+3 = 5

We have to distribute these shirts to 6 children so that each children got one shirt

Number of ways will be equal to =(6!)/(3!3!)=20 ( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )  

What is the value of the ratio of the surface area to the volume of the right prism? A. 1.4
B. 1.07
C. 0.94
D. 0.7

Answers

Surface Area: 2(wl + hl + hw)

w = width ; l = length ; h = height

w = 5 ; l = 6 ; h = 3

Plug them in: 2(5*6 + 3*6 + 3*5) = 126

So the surface area is 126.

Volume = lwh

Same values for the letters

6 * 5 * 3 = 90

The ratio is (126)/(90) = 1.4
Well, the formula for surface area of the prim is perimeter of the base * height + 2 * area of the base
And for volume, it is length * width * height
After finding the values, you can divide the surface area by the volume and ta-daa, you have your ratio. Hope this was helpful. :)

How many miles per hour m over the speed limit is the car traveling?55 – m ≥ 65; m ≥ 10 m + 65 ≤ 55; m ≤–10 65 – m ≤ 55; m ≤ 10 55 + m ≥ 65; m ≥ 10**** 18. Chris earns $7.00 per hour working on the weekends. He needs at least $210.00 for a new cell phone. How many hours, h, does Chris need to work on the weekends to buy a new phone?
h/7.00 > 210.00; h> 30; 30 hours h/7.00 < 210.00; h < 30; 30 hours 7.00h≥ 210.00; h≥ 30; 30 hours** 7.00h≤ 210.00; h ≤ 30; 30 hours

Answers

Answer:

17.)  D.) 55 + m ≥ 65; m ≥ 10

18.)  C.) 7.00h≥ 210.00; h≥ 30; 30 hours

Explanation:

I took the test, also your answers were right.
17. 55 + m ≥ 55

18. 210 / 7 = 30 h 

h ≥ 30 hours

The average cost of tuition and room and board at a small private liberal arts college is reported to be $8,500 per term. A financial administrator believes that the average cost is higher. A study conducted using 350 small liberal arts colleges showed that the average cost per term is $8,745. The population standard deviation is $1,200. Let α

Answers

Answer:

D. +3.82

Step-by-step explanation:

The computation of the test static for this test is shown below:

Data provided in the question

\bar x= $8,745

\mu = $8,500

\sigma = $1,200 and n = 350

Now based on the above information, the test static for this test is

z = (\bar x - \mu)/((\sigma)/(√(n) ) )

z = (\$8,745 - \$8,500)/((\$1,200)/(√(350) ) ) \n

= 3.82

= +3.82

Hence, the test static for this test is +3.82

We simply applied the above formula so that the correct value could come

which term can be added to the list so that the greatest common factor of the three terms is 12h3? 36h3, 12h6,

Answers

Any multiple of 12h^3.

Remember that the greatest common factor is the common terms raised to the lowest power. Then you can include any terms that includes 12h^3

For example, 12h^3, or 24h^12, 60h^9, etc.
