Geometry question, any help is appreciated

Answer:

Hence, the ratios are given by 5:7, 25:49, 125:343.

Step-by-step explanation:

We are given two spheres such that:

Volume of small sphere $V_{s}$ = 250 $yd^{3}$

Volume of large sphere $V_{l}$ = 686 $yd^{3}$ .

Then the ratio of volume = 250 : 686 = 125 : 343.

Since, the volume of a sphere = $\frac{4 \pi \times r^{3}}{3}$ , this gives us that the ratio of the radius = ∛ $V_{s}$ : ∛ $V_{l}$

i.e. The ratio of the radius = ∛125 : ∛343 = 5 : 7.

Further, as the surface area of a sphere = $4 \pi \times r^{2}$ , this gives us that the ratioof surface area = $r_{s} ^{2}$ : $r_{l} ^{2}$

i.e The ratio of the surface area = $5^{2}$ : $7^{2}$ = 25 : 49

So, the ratio of the surface areas = 25 : 49.

Hence, the ratios are given by 5:7, 25:49, 125:343.

How many sites are show in this data set?

andre [41]

Answer:

The total number of sites are 15 .

Step-by-step explanation:

As shown in question.

The number of sites in 2 shield darter = 3

The number of sites in 3 shield darter = 1

The number of sites in 4 shield darter = 4

The number of sites in 6 shield darter = 2

The number of sites in 7 shield darter = 3

The number of sites in 8 shield darter = 1

The number of sites in 9 shield darter = 1

Thus

Total number of sites = Number of sites in 2 shield darter + Number of sites in 3 shield darter + Number of sites in 4 shield darter + Number of sites in 6 shield darter + Number of sites in 7 shield darter + Number of sites in 8 shield darter + Number of sites in 9 shield darter

Putting the values in above

= 3 + 1 + 4 + 2 + 3 + 1 +1

= 15

Therefore the total number of sites are 15 .

Using the expression you found in part a, how many minutes will it take to make and pack an order for 15 parts? Show your work.

Sphinxa [80]

Answer:

2x + 10

= 2(15) + 10

= 30 + 10

= 40

It will take 40 minutes to make and pack an order for 15 parts.

Find the value of the variable What is x?

yaroslaw [1]

Answer:

x = 7

Step-by-step explanation:

I think there may be other ways to do this ... but this is one I guess....

one angle= 90 ( given)

the other = 45 (given)

the third = 90 + 45 + a = 180

(all angles of triangles is 180 [angle sum property])

a = 180 - 135

= 45

The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so

if one side is 7

the x is 7 too

(as it cant be the hypothenus)

I think this is right
