Answer:
x= 2 and x= -6
Step-by-step explanation:
3(x+2)^2=48
1) [3(x+2)^2]/3=48/3
2) (x+2)^2 = 16
3) √(x+2)^2 =+/-√16
4) x+2 = 4 and x+2 = -4
5) x=2 and x= - 6
Check:
3(x+2)^2=48
3(2+2)^2 = 48 and 3(-6+2)^2=48
48 = 48 48=48

What is mean by Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
We have to given that;
Inequality is,
⇒ x - 3 < 2
Now, We can simplify as;
⇒ x - 3 < 2
Add 3 both side,
⇒ x - 3 + 3 < 2 + 3
⇒ x < 5
Hence, By options all the solutions are,
⇒ x = - 3, 0 , 2

Kim works at an ice-cream store. She wants to calculate how much ice-cream one cone can hold. If the cone is 6 inches tall and the circular opening at the top is 2.5 inches across, how much can the cone hold? Round to the nearest tenth at the end.
Answer:
The cone holds 9.8 cubic inches ice cream
Step-by-step explanation:
Height of cone = 6 inches
The circular opening at the top is 2.5 inches across
Diameter of cone = 2.5 inches
Radius of cone = [tex]\frac{2.5}{2}=1.25[/tex]
Volume of cone = [tex]\frac{1}{3} \pi r^2 h[/tex]
Volume of cone = [tex]\frac{1}{3} \times 3.14 \times 1.25^2 \times 6[/tex]
Volume of cone = [tex]9.8125 in^3[/tex]
Hence the cone holds 9.8 cubic inches ice cream.

Scenario 1
Karissa has been working at her job in retail for three years. She’s looking forward to the raise she’ll be getting next month when the minimum wage goes up by $0.50. She plans to use some of the extra money to pay her bills and save the rest.
Scenario 2
Marta has owned her popular clothing store for 10 years. She prides herself on offering good service to all her customers. To achieve this level of service, she has always had five employees work in the store every day. She will have to increase the hourly wage she pays her employees next month when the minimum wage goes up. She is concerned about how she will come up with the extra money to pay her employees. She’s trying to decide between two options: increasing the prices she charges for items and reducing the number of employees working in the store each day.
How do Karissa and Marta differ in their reactions to the increase in the minimum wage?
Answer:
Karissa is happy with the increase in minimum wage. She will be able to save money.
Marta is worried because she has to choose between increasing the prices of her items and reducing the number of employees.

Suppose the equation h =− 16t2 + 35t models the altitude a football will reach t seconds after it is kicked. Is it possible for the football to reach 16 ft in the air? Justify your answer.
Answer:
The ball will be able to reach the 16 ft.
Step-by-step explanation:
In order to calculate if the ball will be able to reach that height, we must make "h" equal to 16, if there's a real positive solution, then the ball will be able to reach it.
16 = -16t² + 35t
16t² - 35t + 16 = 0
t = [-(-35) +- sqrt((-35)² - 4*16*16)]/(2*16)
t = [35 +- sqrt(1225 - 1024)]/32
t = [35 +- sqrt(201)]/32
t = (35 +- 14.177)/32
t1 = 0.65071875
t2 = 1.5367
The ball will reach that height at 0.65 s and 1.53 s.

A positive and a negative become a negative. First you convery the mixed fraction into an improper fraction, then you find the common denominator of all fractions, next step according to PEMDAS, you can add and subtract in any order you would like too.
1. -7 2/3 - 5 1/2 + 8 3/4
2. -23/3 - 11/2 + 35/4
3. -92/12 - 66/12 + 105/12 The common denominator is 12.
4. -92/12 - 66/12 = -158/12 A negative and a negative is addition but just add the negative sign.
5. -158/12 + 105/12 = -53/12 =
Answer= -4 5/12
This is my way of doing it but according to PEMDAS any other order of doing it is fine also!

(-5+6) + (-9-23)
Find the sum
Answer:
-31
Step-by-step explanation:
-5+6=1
-9-23=-32
1+-32=-31
Answer:
The answer is -31
Step-by-step explanation:
First, you would add everything in the parenthesis. Negative 5 added to 6 gives you a sum of 1, while negative 9 subtracted from 23 would give you negative 32. Once you have these two values, simply combine the totals to get negative 31
(1) + (-32) = -31 :)

Joe has 10 marbles. Ken has fewer marbles than Joe. Which inequality represents the
number of marbles m that Ken has?
m
= 10
m
<10
m
> 10
m
< 10
Answer:
The 2nd and 4th (m<10)
Step-by-step explanation:
The symbol used is a less than sign, so the inequality is saying m is less than 10, and since Ken=m Ken has fewer marbles.

what is the center?
the circle passes through the point (-7,-7). what is the radius?
We have been given image of circle that passes through point [tex](-7,-7)[/tex]. We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point [tex](-2,-1)[/tex].
Now we will use equation of circle to find radius.
[tex](x-h)^2+(y-k)^2=r^2[/tex], where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point [tex](-7,-7)[/tex] and coordinates of center [tex](-2,-1)[/tex] and solve for r as:
[tex](-7+2)^2+(-7+1)^2=r^2[/tex]
[tex](-5)^2+(-6)^2=r^2[/tex]
[tex]25+36=r^2[/tex]
[tex]61=r^2[/tex]
Switch sides:
[tex]r^2=61[/tex]
Now we will take positive square root on both sides:
[tex]\sqrt{r^2}=\sqrt{61}[/tex]
[tex]r=\sqrt{61}[/tex]
Therefore, radius of circle will be [tex]\sqrt{61}[/tex] and center is at point [tex](-2,-1)[/tex].
