50= - 10t+80
We move all terms to the left:
50 - ( -10t+80) =0
Get rid of the parentheses
10t - 80+50=0
We add all the numbers together, and all the variables
10+ - 30=0
We move all the terms containing t to the left, all the other terms to the right
10t = 30
t = 30/10
t = 3

The sphere is centered in the cube. Find an expression for the volume of the cube outside the sphere
Nikolay [14]

Solution -

The sphere is centered in the cube, so diameter of the sphere is equal to the side of the cube. Hence ,the radius of the sphere is half of the length of the side.

If the length of side of the cibe = a , then radius of the sphere is \frac{a}{2}

Volume of the cube = a³, volume of the sphere = \frac{4}{3}π(radius)³ = \frac{4}{3}π(\frac{a}{2})³

volume of the cube outside the sphere = volume of the cube - volume of the sphere

=  a^3 - \frac{4}{3}π(\frac{a}{2})³

= a^3 -\frac{1}{6} \pi a^{3}

=a³(1 - \frac{\pi }{6})

Please help me with this math question.
alex41 [277]

Answer:

275 m^3

Step-by-step explanation:

The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.

First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.

In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.

Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so

V=(1/3)(75/2)*22=275

The point is plotted on the number line.What whole number best approximates the value of x?
sattari [20]

You can eliminate 81 because we know \sqrt{81} =9

The dot is on approximately 9.32 (my estimate) so I would square that number:

(9.32)² = 86.8624 so if you round this you get 87

When Natalie finishes drawing the large triangle on the poster board, what will be the approximate measure of side BC? Round to
gtnhenbr [62]

Answer:

31 cm

Step-by-step explanation:

The complete question is attached.

A triangle is a polygon with three sides (three edges and three vertices). There are different types of triangles which are equilateral triangles, right triangles, scalene triangles, obtuse triangles, acute triangles, and isosceles triangles.

An equilateral triangle is a triangle in which all its sides are equal and all its angles are equal to 60°.

From the triangle, AB = BC = AC = 9.5 cm

Since the triangle is enlarged 3.25 times, hence:

new length of BC = 9.25 cm × 3.25 = 30.875

New length of BC = 31 cm to nearest cm

Write the equation in slope-intercept form. What are the slope and y-intercept?
Schach [20]
Slope intercept form is y=mx+b

Y= y intercept
M = slope
B = x intercept

-2x-11y= 5              get the y by itself
-11y = 2x + 5            divide by -11



y = -2/11x + 5/11

slope is -2/11
