5 pts Question 17 - + - = -6/14 -7/8 6/24 09/14

Nady [450]

Answer:

-7/8

Step-by-step explanation:

$\frac{ - 3 \times 8}{6 \times 8} + \frac{ - 3 \times 6}{8 \times 6} = \frac{ - 24 - 18}{48} = \frac{ - 42}{48}$

$= \frac{ - 7}{8}$

The value of y varies directly with x, and y = 48 when x = 16. Find y when x = 176.

emmainna [20.7K]

Try to find what y is when x is equal to one.

48/16= 3

So, when x is 1, y is 3.

(1,3)

All you need to do is multiply 176 by 3 for the correct value of y.

176*3= 528

When x= 176, y= 528. (176,528)

What are all of the prime factors of 35?

neonofarm [45]

Answer:

Well, the only prime factor of 35 would be 5 × 7.

Step-by-step explanation:

For addition, all of the number 35's divisors would be:

1, 5, 7, 35.

Which means, 5 and 7 are the only numbers that 35 can be divided to besides 1 and itself.

Hope this helps!

A sphere is inscribed in a cube with a surface area of 216 square centimeters. What is the volume of the sphere

pentagon [3]

Answer:

$V=298.5cm^3$

Step-by-step explanation:

To find the volume of the sphere we need to know its radius.

And the radius can be found with the information we have about the surface area.

The formula for the surface area is as follows:

$SA=4\pi r^2$

from this formula we clear the radius r:

$r^2=\frac{SA}{4\pi}\\ \\r=\sqrt{\frac{SA}{4\pi} }$

and we substitute the known value of the surface area, and also the value of $\pi$ :

$r=\sqrt{\frac{216cm^2}{4(3.1416)} }\\ \\r=\sqrt{\frac{216cm^2}{12.5664} }\\ \\r=\sqrt{17.1887cm^2}\\ \\r=4.146cm$

and now that we know the radius we find the volume:

$V=\frac{4\pi r^3}{3} \\\\V=\frac{4(3.1416)(4.146cm)^3}{3}\\ \\V=\frac{895.521cm^3}{3}\\ \\V=298.5cm^3$

the volume of the sphere is $298.5cm^3$

What is liner equation with two variable?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

-10x² -10y² = -300 ----a

5x² + 5y² = 150 ---- b

While trying to solve this,

We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.

10x² + 10y² = 300 ----c

-10x² -10y² = -300 ---a

Everything cutoff, we will get 0, and there is no solution to these equations.
