Answer:

arrow going from 9 to -infinity (open circle)

Step-by-step explanation:

equalize equation by multiplying both sides by 3 to obtain the equation 9>t

then simply plug in numbers to see if they check out, ie: 3> 4/3 makes sense, but 3> 10/3 doesn't.

Draw the arrow to accommodate for the answers that DO fit.

open circle, because it doesn't work for t=9

Answer:

see below

Step-by-step explanation:

3 > t/3

Multiply each side by 3

3*3 > t/3 *3

9 > t

t < 9

There is an open circle at 9, since the symbol is less than

What is the volume of a sphere if its radius is 30

ASHA 777 [7]

Answer:

About 113,097.34 units

Step-by-step explanation:

The volume of a sphere can be found with the equation V = $\frac{4}{3}$ πr³ when r is the radius.

V = $\frac{4}{3}$ πr³

V = $\frac{4}{3}$ π(30)³

V ≈ 113,097.34 units

Your grades on three exams are 80, 93, and 91. What grade do you need on the next exam to have an average of 90 on the four exam

Pani-rosa [81]

<u>Answer:</u>

<u>Step-by-step explanation:</u>

Let's assume that the marks needed in the next exam is $x$ . Then if the average becomes 90,

$\frac{80 + 93 + 91 + x}{4}= 90$

Now we can simply solve for $x$ :

⇒ $\frac{264 + x}{4}= 90$

⇒ $264 + x = 360$ [Multiplying both sides by 4]

⇒ $x = 360 - 264$ [Subtracting 264 from both sides]

⇒ $x = \bf96$

Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.

Helpp guys thank youu

1. if we add something in x then it will also add up in value of y

2. x by 5 times then y value increases by 3*5 = 15 times

3. if x is added with 5 then y value increases by 8.

<h3>What is Algebra?</h3>

Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.

As, per the first part

y=x

So, if we add something in x then it will also add up in value of x.

In second part,

y=3x

If x by 5 times then y value increases by 3*5 = 15 times

In third part, if x is added with 5 then y value increases by 8.

miskamm [114]

First multiply 76 by 80/100
(76 x 80 )/100 = 60.8

Now because the price has to be reduced...
76 - 60.8 = $15.2

Hope this will help.
