After cross multiplying you will get 760,507,625x = 60,078,818,800
Then you will divide by 760,507,625 to isolate the varible to get 78.99 = x.
Your equation in number two is 80/143 = x/100 because when you subtract 143 by 63 you get 80, the amount of males in the room. Then you cross multiply to get, 143x = 8000. Then you would divide both sides by 143 to isolate the varible to get 55%

Let a, b, c, and d be constants. Describe the possible solution sets of the inequality ax+b
Answers
An inequality's solution set is determined by its specific properties. For a quadratic inequality, it can be solved by first finding the roots with the quadratic formula and then testing ranges between the roots to see where the inequality holds.
Explanation:The question seems a bit incomplete, as there is no inequality provided related to constants a, b, c, and d. Typically, if we had a complete inequality, the solution set would depend on the specifics of the inequality. For instance, if we took a quadratic inequality, ax²+bx+c>0, or ax²+bx+c<0, we would solve it by finding the roots using the quadratic formula (-b ± √b² - 4ac) / 2a, which gives us the values of x where the expression equals zero, and testing regions determined by these roots to find where the inequality holds. However, without a specific inequality provided, it's difficult to describe the possible solution sets accurately.

Answers
Answer with Step-by-step explanation:
1. x-7>10
Adding 7 on both sides,we get
x>17
2. 3x ≤ 21
Dividing both sides by 3,we get
x≤7

1) determine the y-intercept, and
2) use the given slope to come up with another point on the line.
Looking at the graph, you can easily see that the graph crosses the y-axis at (0,2). Thus, the y-intercept is 2.
Now let's determine the slope of this line:
Begin at the point (-4,0) (which happens to be the x-intercept).
Move 4 units from there to the right. How many units UP must you then travel to reach the graph? call this "m."
Then the slope is m/4.
Then the equation of the line is y = mx + b, or
y=(1/2)x + 2 or y = x/2 + 2
Jason is standing on the ground and throws a ball vertically upward with an initial speed of 80 ft/sec. Its height after t seconds is given by h = 80t-16t^2
a) How high does the ball go?
b) How many seconds does it take to reach maximum height?
c) When does the ball hit the ground?
Answers
Using calculus,
the velocity equation will be the derivative of the h function that gives.
v=80-32t
At its highest point the velocity=0, so we set v=0 and solve for t.
0=80-32t
32t=80 t=2.5 seconds
the height at this point would be
h=80(2.5)-16(2.5)^2
h=200-16(6.25)=200-100=100
A) h=100ft
B) at t=2.5 seconds
The ball will take an additional 2.5 seconds to come back down. Therefore the total time for it to hit the ground would be
C) 5 seconds.

Mariah borrowed 15 books from the library last month. She's already read 2/5 of them. How many of the 15 books has she read?
Answers
___________________________________________
Explanation:
___________________________________________
The number of books is: "(⅖)*15" .
___________________________________________
Method 1)
___________________________________________
[tex] \frac{2}{5} [/tex] * 15 = [(15 ÷ 5) * 2] = 3 * 2 = 6 .
___________________________________________
Method 2)
___________________________________________
[tex] \frac{2}{5} [/tex] * 15 ;
= [tex] \frac{2}{5} [/tex] * [tex] \frac{15}{1} [/tex] ;
= [tex] \frac{2*15}{5*1} [/tex] = [tex] \frac{30}{5} [/tex] = 6 .
_________________________________________________
Method 3)
_________________________________________________
[tex] \frac{2}{5} [/tex] * 15 ;
= [tex] \frac{2}{5} [/tex] * [tex] \frac{15}{1} [/tex] ;
→ At this point, we can "cancel out" the "5" to a "1"; &
we can "cancel out" the "15" to a "3" ;
→ {Since: "15 ÷ 5 = 3" ; and since: "5 ÷ 5 = 1"}.
→ And rewrite as: = [tex] \frac{2}{1} [/tex] * [tex] \frac{3}{1} [/tex] ;
→ At this point, we can rewrite as:
" 2 * 3 " ; and: "2 * 3 = 6 " .
→ {since: "any value, divided by "1", equals that same value};
As such: " [tex] \frac{2}{1} [/tex] = 2 "; AND: [tex] \frac{3}{1} [/tex] = 3 .
→ So: [tex] \frac{2}{1} [/tex] * [tex] \frac{3}{1} [/tex] = {2 * 3} = 6 .
→ Alternately, we can continue as follows:
[tex] \frac{2}{1} [/tex] * [tex] \frac{3}{1} [/tex] ;
= [tex] \frac{2*3}{1*1} [/tex] = [tex] \frac{6}{1} [/tex] = 6 .
______________________________________________________
Method 4)
_____________________________________________________
[tex] \frac{2}{5} [/tex] * 15 ;
= [tex] \frac{2}{5} [/tex] * [tex] \frac{15}{1} [/tex] ;
= [tex] \frac{2*15}{5*1} [/tex]
→ At this point, we can "cancel out" the "15" in the numerator to a "3"; & we can "cancel out" the "5" in the denominator to a "1" ;
{Since: "15 ÷ 5 = 3" ; and since: "5 ÷ 5 = 1" ;
→ and rewrite as follows:
→ [tex] \frac{2*3}{1*1} [/tex] ;
→ At this point: since: "2 * 3 = 6" ; & since "1*1 = 1" ;
We can rewrite as:
→ [tex] \frac{2*3}{1*1} [/tex] = [tex] \frac{6}{1} = 6 .
Alternately, at the point when we have:
→ [tex] \frac{2*3}{1*1} [/tex] ;
→ We can ELIMINATE the "denominator" completely;
Since the denominator, "(1*1)" is equal to "1" ; and since any value (e.g. the "numerator"); divided by "1" (e.g. the value of the denominator); equals the same value (e.g. that same value of the numerator);
As such, we can rewrite; and simplify; our expression (as follows):
→ [tex] \frac{2*3}{1*1} [/tex] = { 2 * 3 } = 6 .

[tex] \frac{2}{5} [/tex] * 15 = ?
→ Convert "[tex] \frac{2}{5} [/tex]" to a decimal value:
Note: [tex] \frac{2}{5} [/tex] = ? / 10 ???
What value belongs in the "question mark" ??
→ Let us examine the denominators.
We have "5" and "10".
→ 5 * (what value?) = 10? (answer: "2" , by recognition);
→Nonetheless, to get that value: "10 ÷ 5 = ? " ; The answer is: "2" ;
→ To confirm: "5 * 2 =? 10? Yes!
→ As such: [tex] \frac{2}{5} [/tex] ;
= [tex] \frac{2*2}{5*2} [/tex] ;
= [tex] \frac{4}{10} [/tex] ;
Convert this value to a decimal value;
→ 4/10 = 4 ÷ 10 ;
→ To divide by "10" ; Take the decimal value (The decimal value in "4" is considered the value "directly after the "4"); and move that value backward ONE decimal space; {since we are DIVIDING by "10" ; and "10" has ONE "zero"}; to get: ".4" ; → Write as: "0.4" ;
→ [tex] \frac{2}{5} [/tex] = [tex] \frac{4}{10} [/tex] = 0.4 .
Alternately, use a calculator to convert "[tex] \frac{2}{5} [/tex]" to a decimal value:
→ [tex] \frac{2}{5} [/tex] = 2 ÷ 5 = 0.4 .
Now, we can rewrite:
→ [tex] \frac{2}{5} [/tex] * 15 ;
as: "(0.4)(15)" ; & calculate:
→ (0.4)(15) = 6 .

Answer:
The domain of the function is {0,1,2,3,4} and the range of the function is {$33, $44, $55, $66, $77}
Step-by-step explanation:
Consider the provided information.
Sarah has sold $33 worth of tickets sales to the comedy show. She has 4 tickets left to sell at $11 per hour.
First write the function as shown.
Let the number of tickets are x and she already sold $33 worth of tickets.
Therefore the function is: [tex]f(x)=11t+33[/tex]
For t=0
[tex]f(0)=11(0)+33=33[/tex]
For t=1
[tex]f(1)=11(1)+33=44[/tex]
For t=2
[tex]f(2)=11(2)+33=55[/tex]
For t=3
[tex]f(3)=11(3)+33=66[/tex]
For t=4
[tex]f(4)=11(4)+33=77[/tex]
Hence, the domain of the function is {0,1,2,3,4} and the range of the function is {$33, $44, $55, $66, $77}
Marco wants to set up 12 small turbines with 3 blades each.If 4 wind turbines blades cost $79.64,how much will all the blade cost?
Answers
If Marcos has 12 turbines with 3 blades / turbine, then 36 blades. If 4 blades cost $ 79.64, then how much do the 36 blades cost?
Let's make a simple three rule:
Blade ___ price
4 ----------- 79.64
36 --------- y
4 * y = 36 * 79.64
4y = 2,867.04
[tex]y = \frac{2,867.04}{4} [/tex]
y = 716.76
The 36 blades cost $ 716.76
If Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64 then $716.76 costs for all blades.
What is Equation?Two or more expressions connected with an equal sign is called ad equation.
Given Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64, then we have to find the cost of all blades.
Each turbine has 3 blades, so for 12 tubines we have
3×12=36 blades.
If 4 blades cost is $79.64, then we have to find cost of 36 blades.
Let y be the cost of 36 blades.
4 /36= 79.64/y
Use cross multiplication,
4 * y = 36 * 79.64
4y = 2,867.04
y=716.76
Therefore 36 blades cost is $ 716.76.

Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km left to bike. If Dina’s biking speed was 5 km/h, find Masha’s biking speed.
Answers
Answer:
4 km/hr
Step-by-step explanation:
Dina and Masha started out on a 10 km bike path at the same time.
Distance = 10 km
Dina’s biking speed was 5 km/h
Time taken by Dina is Distance / speed
So [tex]time (Dina) = \frac{10}{5} =2[/tex]
Time taken by Dina is 2 hours
Same time is taken by Masha but 2 km left
So distance covered by Masha in 2 hours is 10-2 = 8 km
We know speed = distance / time
[tex]speed of Masha = \frac{8}{2}=4[/tex]
Masha’s biking speed= 4km/hr
