Answer:x=14
Step-by-step explanation:
for plato users
The solution of the rational equation 24/(x-8) = 4 is x = 14.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given:
A rational equation,
24/(x-8) = 4.
Simplifying,
x - 8 = 6
x = 8 + 6
x = 14.

Daniel worked for 2 hours and earned $18.20.
How much would he make if he worked for 5 hours?
Enter your answer in the box.
Answer:
$45.50
Step-by-step explanation:
First we'll need to solve for how much Daniel earns per hour.
So 18.20/2 = $ 9.10
Then we'll be multiplying this value by 5 since the question is asking how much he earns if he works for 5 hours.
$ 9.10 x 5 hours = $45.50

Answer:
65 degrees
Step-by-step explanation:
Answer:
Option B is correct 65°
Step-by-step explanation:
Apply the trigonometric identity sine
[tex]sin\ x=\frac{6.1}{6.7}\\\\sin\ x= 0.9104\\x=sin^{-1}(0.9104)\\x=65[/tex]
Do not forget to convert your calculator into degree form if it is set to radian.
Alright since you haven't studied trigonometry forget what i said here xD
The table given are the ratios of the respective angles 55, 65, 75.
First we need the adjacent side of the triangle. We have the opposite side of the triangle which is 6.1 and the hypotenuse which is 6.7 we use Pythagoras theorem
[tex]a^2+b^2=c^2\\a^2+(6.1)^2=(6.7)^2\\a^2=(6.7)^2-(6.1)^2\\a^2=7.68\\a=\sqrt{7.68}\\a=2.77 \\[/tex]
So now lets compare the ratios in table
Firstly
[tex]\frac{adjacent\ leg \ length}{hypotenuse\ leg \ length} = \frac{2.77}{6.7}=0.413\\\\\frac{opposite\ leg \ length}{hypotenuse\ leg \ length}=\frac{6.1}{6.7}=0.91 \\\\\frac{opposite\ leg \ length}{adjacent\ leg \ length}=\frac{6.1}{2.77}=2.2[/tex]
so we can see that all these values 0.413, 0.91, 2.2 correspond to the angle 65° so Option B is correct

Consider the function f(x) = (x+ 1)2 - 1. Which of the following functions stretches
fo) vertically by a factor of 4?
O A) f0 - (/ax+ 1)2 +3
O B) f9 = 1/ax+ 1)2 -4
Oo fo-4(x+ 1)2 - 1
OD) fo = 4(4x+ 1)2- 1
Answer:
C
Step-by-step explanation:
A coefficient of 4 would have to be added in front of (x+1)^2 in order to vertically stretch the function by a factor of 4.
The answer that demonstrates this is choice C: [tex]f(x) = 4(x+1)^2-1[/tex]
The functions stretches vertically by a factor of 4 will be f(x) = 4(x+ 1)² - 1. Then the correct option is C.
What is the equation of the parabola?Let the point (h, k) is the vertex of the parabola and a is the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic function is given below.
f(x) = a(x+ 1)² - 1
If the value of the leading coefficient lies between 0 to 1. Then the parabola is stretched horizontally.
And if the value of the leading coefficient is greater than one. Then the parabola is stretched vertically.
The functions stretches vertically by a factor of 4. Then the value of the leading coefficient is 4. Then the equation will be
f(x) = 4(x+ 1)² - 1
Then the correct option is C.

Put the following equation of a line into slope-intercept form, simplifying all fractions.
6x+10y= -80
Answer:
y=-0.6 X-8
Step-by-step explanation:
6x+10y= -80
Subtract the positive 6x from both sides of the equation
This will make your equation look like 10y= -80-6x
(If it helps you can rewrite the equation so it looks like 10y= -6x -80)
Divide both sides of the equation by 10. This will isolate your Y axis
Now your equation will look like y= (-6x -80) / 10
I got y= -0.6x -8
I hope this helps and it is correct :)

Expression A Expression B Expression C (−5)(−0.4)(1.8) (-45)(-19)(-112) −1(5+17) Expression D Expression E Expression F (−5)(−0.4)(1.8)(−3.25) (-49)(-34)(-12)(-12) −1(3.5−7) How many expressions will have a product that is positive?
Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.

There are 30 birds in an enclosure at the zoo. 1/5 of the birds are native to North America. 1/3 of the birds are native to South America. The remaining birds are native to Australla. How many of the birds in the enclosure are Native to Australla? Plz helppppppppp
Answer:
Number of Australia birds = 14
Step-by-step explanation:
Given:
Total number of birds = 30
North america birds = 1/5 birds = 30/5 = 6 birds
South america birds = 1/3 birds = 30/3 = 10 birds
Find:
Number of Australia birds
Computation:
Number of Australia birds = Total number of birds - North america birds - South america birds
Number of Australia birds = 30 - 6 - 10
Number of Australia birds = 14

Two hot air balloons are flying above a park. One balloon started at a height of 3,000 feet above the ground and is decreasing in height at a rate of 40 feet per minute. The second balloon is rising at a rate of 50 feet per minute after beginning from a height of 1,200 feet above the ground.
Given that h is the height of the balloons after m minutes, determine which system of equations represents this situation.
A.
h = 3,000 + 40m
h = 1,200 - 50m
B.
m = 3,000 - 40h
m = 1,200 + 50h
C.
h = 3,000 - 40m
h = 1,200 + 50m
D.
h = 3,000m - 40
h = 1,200m + 50
Answer:
C
Step-by-step explanation:
Because c has the variables in the right spot and the other ones don't make scene

Answer:
23%
Step-by-step explanation:
There are 52 cards in a deck… 12 of these are Face Cards (the J - Q - K of all four suits). The probability of getting one of these is therefore 12 out of 52 — or 12/52, which is 23%.
