Evaluate x(y+3)/(3+y)z for x=12, y=1, and z=6.
A) 2
B) 5
C) 8
D) 6
Answers
Answer:
2
Step-by-step explanation:
We take the equation
[tex]x(y+3)/(3+y)z[/tex]
and substitute the values for each individual variable in the problem. It looks like this:
[tex]12(1+3)/(3+1)6[/tex]
Now we can solve the equation.
When solved, it equals 2.
h= -16t^2+16t+192 When will the ball hit the ground?
Answers
Answer:
t = 4 s
Step-by-step explanation
We can infer the origin from the t⁰ term of the quadratic as being 192 feet above the ground. Initial velocity is 16 ft/s from the t¹ term, gravity is -32 ft/s² from the t² term
0 = -16t² + 16t + 192
0 = -t² + t + 12
0 = t² - t - 12
0 = (t - 4)(t + 3)
so either
t - 4 = 0
t = 4 s
or
t + 3 = 0
t = -3 s which we ignore as it occurs before the ball is released.

Kendra is practicing to take an aptitude test. In order to pass, she must have a score of at least 1,396. On the first official test she took, she made a score of 986. After studying, she took a practice test and raised her score by 68 points. Assuming her score continues to rise by 68 points each time she retakes the practice test, which inequality could be used to find t, the number of practice tests that Kendra would need to take before she is ready to pass the official test?
A.
(986 + 68)t < 1,396
B.
(986 + 68)t > 1,396
C.
986 + 68t < 1,396
D.

550 tickets were sold for a game for a total of $712.50. If adult tickets sold for $1.50 and children's tickets sold for $1.00, how many of each kind of ticket were sold?
Answers
9514 1404 393
Answer:
adult: 325children's: 225Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.

The value of solution of equation is,
⇒ x = ±1 and x = ±√2
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
Expression is,
⇒ x⁴ - 3x² + 2 = 0
Now, We can plug x² = u in above equation and solve as;
⇒ x⁴ - 3x² + 2 = 0
⇒ u² - 3u + 2 = 0
⇒ u² - 2u - u + 2 = 0
⇒ u (u - 2) - 1 (u - 2) = 0
⇒ (u - 1) (u - 2) = 0
⇒ u = 1
⇒ u = 2
Plug x² = u
⇒ x² = 1
⇒ x = ±1
⇒ x² = 2
⇒ x = ±√2
Thus, The value of solution of equation is,
⇒ x = ±1 and x = ±√2

What is the equation of the line that passes through the point -6 -5 and has a slope of 3/2
Answers
Answer:
y = (3/2)x + 4
Step-by-step explanation:
The equation for a line is y = mx + b. m is the slope, b is the y-intercept, and y and x are points.
First, substitute in the slope.
y = (3/2)(x) + b
Then, substitute in the points.
-5 = (3/2)(-6) + b
Multiply.
-5 = -9 + b
Add 9 to both sides.
b = 4
Therefore...
y = (3/2)x + 4

Step-by-step explanation:
These two triangles are similar. Since they share two angles, the right angle and angle EBD and ABC are congruent. By AA similarity rule, they are similar triangles.
Since they are similar we can set up a proportion of the triangles since similar triangles have proportional side length.
Side AC corresponds with DE
Side AB corresponds with BE
Side BC corresponds with BD
So we can use this proportion theorem, or angle bisector theorem
[tex]\frac{ac}{ab}=\frac{de}{be}[/tex]
Plug in the numbers.

Use the given formula to calculate each option and compare.
Option 1
P = $210000r = 8.5% = 0.085t = 30n = 1Find the PMT:
[tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.085)/(1-(1+0.085)^{-30})=19541[/tex]Find the total interest amount:
30*$19581 - $210000 = $377430Option 2
P = $210000r = 8% = 0.08t = 20n = 1Find the PMT:
[tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.08)/(1-(1+0.08)^{-20})=21389[/tex]Find the total interest amount:
20*$21389 - $210000 = $217780We see option 2 reveals less interest amount, so is more economical.

Carlos has 24 balls of different colors: yellow, red, green, and blue. 17 balls are not red,10 balls are neither yellow nor blue. How many green balls does Carlos have
pls help(if u can pls also explain it)
Answers
Answer:
10 green
Step-by-step explanation:
24 total balls. 17 Not red, so 24-17=7. 7 Red balls. That leaves 17 balls. 10 of them are neither yellow nor blue, and since the amount of red balls has been figured out, we do not need to account for them. 17 balls - 10 not yellow or blue equals 7 balls that can be yellow or blue. 17 balls left, minus the 7 yellow or blue balls equals 10.
