Answer:
x = 18 or -18
Step-by-step explanation:
x^2 + 24^2 = 30^2
simplify
x^2 + 576 = 900
subtract 576 from both sides
x^2 = 324
Take square root of 324
+/- √324
x = 18 x = -18
18 or -18 is the answer

fill in the blanks with <,>,= symbols( -3)+(-19)+6...................(-41)-15+9
[tex]( - 3) + ( - 19) + 6 \\ - 3 + ( - 19) + 6 \\ - 3 - 19 + 6 \\ = - 16[/tex]
#2[tex]( - 41) - 15 + 9 \\ - 41 - 15 + 9 \\ = - 47[/tex]
Now,[tex] - 16 > - 47[/tex]
How?When the number is in negative the smaller number is greater than the greater number.Answer:
(-3)+(-19)+6 [>] (-41)-15+9
Step-by-step explanation:
(-3)+(-19)+6= -16
and
(-41)-15+9= -47
so, -16 is greater than -47

PLS HELP ME WITH THIS QUESTION!!!!!
Answer: 24
Step-by-step explanation:
Let the total number of problems be x.
After 15 minutes, [tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex] problems are left.
After another 15 minutes, [tex]\frac{3}{4}x\left(1-\frac{1}{3})=\frac{3}{4}x\left(\frac{2}{3} \right)=\frac{1}{2}x[/tex] problems are left.
This is equal to 12, meaning x = 24.

point Find the length of segment CD with C(2,3) and D (-3, 15
Step-by-step explanation:
so, if the text is correct, the 2 points are
(2, 3) and (-3, 15).
the length of the line segment is the distance between both points.
did this we use Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.
so,
distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169
distance = sqrt(169) = 13 = length of line segment

Two positive numbers have a difference of 8. The larger number is two more than twice the smaller. Find the two numbers
Let the bigger number be 'p' and the smaller number 'p'.
Since the numbers have a difference of 8, then p - q = 8
& since the larger number is two more than twice the smaller, then
p = 2q + 2
⇒ (2q + 2) - q = 8 [by substituting for equation for p]
q = 6
Since q = 6,
⇒ p - 6 = 8
p = 14
∴ the smaller number is 6 and the bigger 14
Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x=1
Answer:
Step-by-step explanation:
Solve the equation for 0 and 1:
x^3 + 6x -5
Replace x with 0:
0^3 + 6(0) -5 = -5
Replace x with 1:
1^3 + 6(1) -5 = 1+6 -5 = 2
Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0

I'd prefer if you answer both questions.
Answer:
2nd answer, and 5 hours
Step-by-step explanation:
Section 1
The answer is the 2nd one down. The tickets are selling at a rate of
floor tickets: 100/h; stand tickets: 75/h
Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.
Section 2
There are only 375 stand tickets left to sell.
Every 2 hours 150 are sold or you can also say 75 per hour.
If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.
375/75 = 5 hours
