At a team meeting, 80% of the tennis team was there. If there were 12
people at the meeting, how many
people are on the team?
Answer:
15 people
Step-by-step explanation:
let x=total # of people on the team
80%=12

cross multiply
80x=1200
division property of equality (divide both sides by 80)
x=15
There are 15 people on the team.
The time required to drive a fixed distance varies inversely as the speed. It takes 40 hr at a speed of 10 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?
Answer:
50 hours
Step-by-step explanation:
Given data
Time=40hr
Speed=10km/hr
Let us find the fixed distance first
Speed= distance/Time
10= distance/40
distance= 10*40
distance= 400miles
Now our speed= 8km/h
hence the time is
8= 400/time
time= 400/8
time=50 hours
Hence the time is 50 hours

The floor of a storage unit in the shape
of a rectangular prism has an area of 106 1/4 square feet. The height of the storage unit is 7 1/2 feet. What is the volume of the storage unit?
A. 742 1/8ft B. 744 1/4 ft C. 795 1/4 ft D. 796 7/8 ft
Answer:
V = 796 7/8 ft^3
Step-by-step explanation:
The storage unit has a rectangular shape.
Thus, the volume is V = (area of floor)(height)
V = (106 1/4 ft^2)(7 1/2 ft)
V = 796 7/8 ft^3
Converting 106 1/4 ft to 106.25 makes it easier to use a calculator here. Same with 7 1/2 ft: 7.5 ft

If c is a positive number, how many solutions does √x = c have? Explain.
Answer:
varied
square root of number never result negative number
Step-by-step explanation:
There will only be one real solution.
If [tex]x[/tex] is a real number, the square root function [tex]\sqrt x[/tex] will only have real solutions when [tex]x\ge0[/tex].
For [tex]x<0[/tex], we get imaginary solutions.
Also, when [tex]\sqrt x> 0[/tex], [tex]x>0[/tex]
In other words, when the square root of [tex]x[/tex] is a positive real number, [tex]x[/tex] will be a unique positive number.
We can see this when trying to solve the equation given in the question
So, the equation
[tex]\sqrt x=c[/tex]
where [tex]c>0[/tex], when solved, will give
[tex]\sqrt x=c\\(\sqrt x)^2=c^2\\x=c^2[/tex]
We will have a unique solution because squaring a positive real number gives a single result.

luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice.she gives 5/8 cup of juice to mags. how much is left in lunas glass
Answer:4/8 or simplified answer 1/2
Step-by-step explanation:
3/4 + 3/8, first you have to find the highest common factor of 4 and 8.
The answer is 9. The denominator of both side will be 8. Now you ask yourself 4 times what gives you 8 and times the numerator by that number. And do the same for the 8.
6/8 + 3/8= 9/8
9/8 - 5/8= 4/8
The simplified answer is 1/2

What are the solutions of the equation (x - 3)2 + 2(x - 3) - 8 = 0? Use u substitution to solve.
Ox= -5 and x = 1
O x= -1 and x = 5
O x= -1 and x = -7
Ox= 1 and x = 7
Given:
The equation is:
[tex](x-3)^2+2(x-3)-8=0[/tex]
To find:
The value of x.
Solution:
We have,
[tex](x-3)^2+2(x-3)-8=0[/tex]
Substitute [tex]x-3=u[/tex].
[tex]u^2+2u-8=0[/tex]
Splitting the middle term, we get
[tex]u^2+4u-2u-8=0[/tex]
[tex]u(u+4)-2(u+4)=0[/tex]
[tex](u-2)(u+4)=0[/tex]
Using zero product property, we get
[tex]u-2=0\text{ and }u+4=0[/tex]
[tex]u=2\text{ and }u=-4[/tex]
Now, substitute [tex]u=x-3[/tex].
[tex]x-3=2\text{ and }x-3=-4[/tex]
[tex]x=2+3\text{ and }x=-4+3[/tex]
[tex]x=5\text{ and }x=-1[/tex]
Therefore, the correct option is b.
The solutions to the equation are x = -1 and x = 5. The correct option is second option x = -1 and x = 5.
Quadratic equationFrom the question, we are to determine the solution of the given equation
(x - 3)² + 2(x - 3) - 8 = 0
First, we will expand the equation and clear the brackets
[tex](x - 3)^{2} + 2(x - 3) - 8 = 0[/tex]
[tex](x - 3)(x - 3) + 2(x - 3) - 8 = 0[/tex]
[tex]x^{2} -6x + 9 +2x - 6 - 8 = 0[/tex]
Simplifying
[tex]x^{2} -4x - 5 = 0[/tex]
Factorizing, we get
[tex]x^{2} -5x +x- 5 = 0[/tex]
[tex]x(x-5)+1(x- 5) = 0[/tex]
[tex](x+1)(x-5)= 0[/tex]
Then,
x + 1 = 0 or x - 5 = 0
x = -1 or x = 5
Hence, the solutions to the equation are x = -1 and x = 5. The correct option is second option x = -1 and x = 5.
