Answer:

Step-by-step explanation:

The solution to a system of equations given graphically is at the point of intersection of the 2 lines.

There is only 1 point of intersection, thus one solution at (2, - 1 )

Baruch college has 1000 students in the spring of 2018. 30 percent of the students use the gym twice per week, 70 percent of the

astraxan [27]

Answer:

The average per week flow rate of students to the gym is <u>2700</u>.

Step-by-step explanation:

Given:

Baruch college has 1000 students in the spring of 2018. 30 percent of the students use the gym twice per week, 70 percent of the students use the gym three times a week.

Now, to find the average per week flow rate of students to the gym.

Total number of students = 1000.

So, 30 percent of the students use the gym twice per week:

$30\%\ of\ 1000\times 2\\\\=\frac{30}{100}\times 1000\times 2\\\\=0.30\times 1000\times 2\\\\=600.$

Now, 70 percent of the students use the gym three times a week:

$70\%\ of\ 1000\times 3\\\\=\frac{70}{100} \times 1000\times 3\\\\=0.70\times 1000\times 3\\\\=2100.$

Now, to get the average per week flow rate of students to the gym by adding 30 percent of the students use the gym twice per week and 70 percent of the students use the gym three times a week:

$600+2100$

$=2700.$

Therefore, the average per week flow rate of students to the gym is 2700.

B. 8/27 D. 1/3 10. Three spheres of radii , 2r, and 3r, respectively, are melted and formed into a new sphere. Find the surface

Dahasolnce [82]

Answer:

$A_{f}=4\pi (\sqrt[3]{36} r)^{2}\\\\V_{f}=\frac{4}{3} \pi (36r^{3})$

Step-by-step explanation:

In order to find the final radii of the sphere, we need to calculate the volume, knowing that volumes are additive:

$V_{1}=\frac{4}{3} \pi (r^{3})\\\\V_{2}=\frac{4}{3} \pi (2r)^{3}\\\\V_{3}=\frac{4}{3} \pi (3r)^{3}\\\\V_{f}=\frac{4}{3} \pi (r^{3}+(2r)^{3}+(3r)^{3})\\\\V_{f}=\frac{4}{3} \pi (r^{3}+8r^{3}+27r^{3})\\\\V_{f}=\frac{4}{3} \pi (36r^{3})\\\\V_{f}=\frac{4}{3} \pi R^{3}\\\\R=\sqrt[3]{36} r$

Now that we know the radii of the new sphere, we can calculate the surface area:

$A_{f}=4\pi R^{2}\\\\A_{f}=4\pi (\sqrt[3]{36} r)^{2}$

What fatal mistake, from a Naturalist's perspective, does the man in Jack London's "To Build a Fire" make?

NISA [10]

The answer would be A. He doesn't acknowledge the power of nature. He believes that he has more time and resources but of course, this was not the case and the cold had overtaken him.

In a fishing community of 9400 people, the number of women exceeds the number of men by 1500. Find the ratio of men to women in

Dovator [93]

M=men
w=women
m+1500=w
m+1500+m=9400
2m+1500=9400
2m=9400-1500
2m=7900
m=7900/2
m=3950

w=3950+1500
w=5450
