Answer:
A.2
Step-by-step explanation:
x² = 16
take the square root of both sides
x = ±4
there are 2 solutions to the equations, those 2 solutions being 4 and -4
just to double check
4² = 4 × 4 = 16
-4² = -4 × -4 = 16
A game app costs a base fee of $5.
You can download additional booster packs for $1.50 per pack.
If you spend a total of $23 on the game, which equation correctly models the situation, where n is the number of booster packs purchased?
Answer:
Step-by-step explanation:
So you have a constant value of 5 dollars and a variable value of 1.50 dollars. some equation of these numbers equals 23 dollars. That equation is
23=5+(1.50n) where n is the number of booster packs.
Answer:
$23 = $5 + 1.5x
Step-by-step explanation:
We can make a format to find the equation.
Total = base fee + $ per pack
Let x = the number of packs
Therefore, the equation will be like this:
$23 = $5 + 1.5x

Answer:
1.) 1169
2.) 7
3.) 167 students/year
4.) 1879
5.) 1879+167t
6.) 4050
Step-by-step explanation:
1.) Find the difference between the number of students in 2002 and 2009:
[tex]3382-2213=1169[/tex]
2.) Find the difference in the years:
[tex]2009-2002=7[/tex]
3.) To find the average growth, find the change between 2002 and 2009 and divide by 7.
[tex](3382-2213)/7=y\\1169/7=y\\167=y[/tex]
4.) To find the population of the students in the year 2000, we need to subtract the average growth time and the difference of years from 2213.
[tex]2213-167(2002-2000) = y\\2213-334=1879[/tex]
5.) Taking the equation above, and changing it to match the requirements, we get:
[tex]P = 1879+167t[/tex]
6.) Now find the difference between 2013 and 2000, and substitute for t to get:
[tex]P = 1879+167(2013-2000)\\P = 1879+167*13\\P = 4050[/tex]

Explain how to use basic facts and number patterns to find 5600%7
Answer:
600.
Well, to divide these numbers, we can use certain strategy that fits with out logic. For example, we know that 56 divided by 7 can be done mentally, because it's a simple division that can be immediately solved.
So, 56 divided by 7 is 8, then we add the two zeros to the quotient, because we isolated the first to digit to make the division easier and then we have to add back those zeros.
Therefore the division results in 600.
There are several operations that can be done by using certain strategy, like separating the number in easier parts like we did this time.

You see that 73 degrees and angle 'a' must add up to be = to 180 degrees since both angles form that straaight line on the left. So 180 degrees - 73 = 107 degrees which is measure of angle 'a'
Step-by-step explanation:
Answer:
107°
Step-by-step explanation:

The first one i would think might be 0.05? uncertian and probably wrong, the second, HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT, and the third, 3/8.
The way you figure out the third one is you are flipping 3 coins still, and you take all of the options above and there are 8 total and 3 ov them would land you 2 heads and a tail so its a simple 3/8 fraction
Answer:
2. 0.05
3. a) 8 outcomes (listed below)
3. b) 3/8
Step-by-step explanation:
Question 2
The sum of the probabilities of all possible outcomes is 1.
Therefore, if the probability of being on time for class is 0.95, then the probability of NOT being on time for class is:
1 - 0.95 = 0.05
Question 3
a) 8 possible outcomes of flipping 3 coins (H = heads, T = tails):
HHH HHT HTH THH
TTT TTH THT HTT
b)
There are 3 possible ways of flipping 2 Heads and 1 Tail:
HHT HTH THH
Out of a total number of 8 possible outcomes.
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

-5x = 60
Answer:
x = -12
Step-by-step explanation:

The expression that represents the total number of customers held by all three companies is 5x + 10
System of equationSystems of equations are made of several equations with unknown variables.
Let the amount of customers company B has be x
If Company C has 10 customers more than company B, then the total customers for company B is x + 10
If Company A has three times as many customers as company B, the total customers for company A is 3x
Total customers = x + 10 + x + 3x

The volume of a sphere is the amount of space in it
The volumes of the spheres are 24416.64, 113.04 and 310181.76
How to determine the volume of the spheres?The volume of a sphere is calculated using:
V = 4/3 πr^3
When the radius, r = 18, we have:
V = 4/3 * 3.14 * 18^3
V = 24416.64
When the radius, r = 3, we have:
V = 4/3 * 3.14 * 3^3
V = 113.04
When the radius, r = 42, we have:
V = 4/3 * 3.14 * 42^3
V = 310181.76
Hence, the volumes of the spheres are 24416.64, 113.04 and 310181.76

Step-by-step explanation:
An astronaut on the moon throws a baseball upward. The astronaut is 6 ft 6 in tall, and the initial velocity of the ball is 40 ft per sec. The height s of the ball in feet is
given by the equation s = -2.7t^2 + 40t + 6.5, where t is the number of seconds after the ball was thrown. Complete parts a and b.
a. After how many seconds is the ball 14 ft above the moon's surface?
After ____ seconds the ball will be 14 ft above the moon's surface.
(Round to the nearest hundredth as needed. Use a comma to separate answers as needed.)
Answer: 0.19s and 14.6s
Step-by-step explanation:
The distance of the ball at any time is given by the function s(t). For now, you can ignore all the details about the height of the man and the intial velocity of the ball. We only care about what time 't' will the ball be 14 feet off the ground. In math terms, they are asking when:
[tex]s(t)=14[/tex]
Where:
[tex]s(t)=-2.7t^2+40t+6.5=14[/tex]
Subtract 14 on both sides:
[tex]s(t)=-2.7t^2+40t-7.5=0[/tex]
Use the quadratic formula to solve for the variable 't'. This will give the possible time values where the ball will be 14 feet off the ground:
[tex]t=-b+\sqrt{b^2-4ac} /2a[/tex]
[tex]t=-b-\sqrt{b^2-4ac} /2a[/tex]
[tex]a=-2.7[/tex]
[tex]b=40[/tex]
[tex]c=-7.5[/tex]
Therefore:
[tex]t=(-40)+\sqrt{40^2-4(-2.7)(-7.5)} /2(-2.7)=0.19s[/tex]
[tex]t=-40-\sqrt{40^2-4(-2.7)(-7.5)} /2(-2.7)=14.6s[/tex]
This is saying the ball almost immediately hits 14 feet given the intial velocity, then it reaches its peak and falls back down to 14 feet again, where it will eventually hit the ground again

What is the solution to the following system?
(3x+2y+z = 20
X-4y-Z=-10
2x+y + 2z = 15
Answer:
x = 4; y = 3; z = 2
Step-by-step explanation:
3x + 2y + z = 20
x - 4y - z = -10
2x + y + 2z = 15
6x + 4y + 2z = 40
x - 4y - z = -10
-------------------------
7x + z = 30
x - 4y - z = -10
8x + 4y + 8z = 60
----------------------------
9x + 7z = 50
z = 30 - 7x
9x + 7(30 - 7x) = 50
9x + 210 - 49x = 50
-40x = -160
x = 4
z = 30 - 7(4)
z = 2
2x + y + 2z = 15
2(4) + y + 2(2) = 15
y = 3
x = 4; y = 3; z = 2
