Answer:
$152
Step-by-step explanation:
To find Yoko's hourly pay, we will divide the $323 she made after working by 17, which is the number of hours she worked:
323 ÷ 17 = 19
We now know that Yoko makes $19 an hour (dang, she's probably a doctor or something) however, we're not done yet.
We will multiply $19 by 8 hours of work to see how much she'll make after 8 hours:
19 × 8 = 152
Yoko makes $152 after 8 hours of work.

In this graph the y-intercept of the line is (Blank). The equation of the line is y=(Blank) x (Blank) .
The equation of the line is y = x - 2.
What is a Line??
A line can be defined by a shortest distance between two points is called as a line.
According to the graph we negative intercept at x =0, y = -2 and two points (0,-2) and (2,0).
Equation can be given as.
y = mx + c
c = -2
m = 0- (-2)/ 2- 0
m = 1
y = x - 2
Thus, the equation of the line is y = x - 2.

Find the measure of angle A.
Question options:
12 degrees
40 degrees
61 degrees
79 degrees
Answer:
40 degrees
Step-by-step explanation:
x= -12
52+(-12)= 40
since all angles are the exact same opposite the angle a would also be 40 degrees.
Given f (x) = 5(2 - x), what is the value of f (-4)?
Answer:
f(- 4) = 30
Step-by-step explanation:
To evaluate f(- 4) substitute x = - 4 into f(x), that is
f(- 4) = 5(2 - (- 4)) = 5(2 + 4) = 5(6) = 30
A bag contains some white and black balls . The probability of picking two white balls one after other without replacement from that bag is 14/33. Then what will be the probability of picking two black balls from that bag if bag can hold maximum 15 balls only?
Answer:
2/35
Step-by-step explanation:
Let w and b be the numbers of white and black balls in the bag respectively.
So, the total numbers of the balls in the bag is
[tex]n=w+b\;\cdots(i)[/tex]
As the bag can hold maximum 15 balls only, so
[tex]n\leq15 \;\cdots(ii)[/tex]
Probability of picking two white balls one after other without replacement
=Probability of the first ball to be white and the probability of second ball to be white
=(Probability of picking first white balls) x( Probability of picking 2nd white ball)
Here, the probability of picking the first white ball [tex]=\frac{w}{n}[/tex]
After picking the first ball, the remaining
white ball in the bag [tex]= w-1[/tex]
and the remaining total balls in the bag [tex]=n-1[/tex]
So, the probability of picking the second white ball [tex]=\frac{w-1}{n-1}[/tex]
Given that, the probability of picking two white balls one after other without replacement is 14/33.
[tex]\Rightarrow \frac{w}{n} \times \frac{w-1}{n-1}=\frac{14}{33}[/tex]
[tex]\Rightarrow \frac{w(w-1)}{n(n-1)} =\frac{14}{33}[/tex]
Here, [tex]w[/tex] and [tex]n[/tex] are counting numbers (integers) and 14 and 33 are co-primes.
Let, [tex]\alpha[/tex] be the common factor of the numbers [tex]w(w-1)[/tex] (numerator) and [tex]n(n-1)[/tex] (denominator), so
[tex]\frac{w(w-1)}{n(n-1)} =\frac{14\alpha}{33\alpha}[/tex]
[tex]\Rightarrow w(w-1)=14\alpha\cdots(iii)[/tex]
And [tex]n(n-1)=33\alpha.[/tex]
As from eq. (ii), [tex]n\leq 15[/tex], so, the possible value of [tex]\alpha[/tex] for which multiplication od two consecutive positive integers (n and n-1) is [tex]33\alpha[/tex] is 4.
[tex]n(n-1)=11\times (3\alpha)[/tex]
[tex]\Rightarrow n(n-1)=12\times11[/tex] [as [tex]\alpha=4[/tex]]
[tex]\Rightarrow n=12[/tex]
So, the number of total balls =12
From equation (iv)
[tex]w(w-1)=7\times (2\alpha)[/tex]
[tex]\Rightarrow w(w-1)=8\times7[/tex]
[tex]\Rightarrow w=8[/tex]
So, the number of white balls =8
From equations (i), the number of black balls =12-8=4
In the similar way, the required probability of picking two black balls one after other in the same way (i.e without replacement) is
[tex]=\frac{b}{n} \times \frac{b-1}{n-1}[/tex]
[tex]= \frac{4}{15} \times \frac{4-1}{15-1}[/tex]
[tex]= \frac{4}{15} \times \frac{3}{14}[/tex]
[tex]= \frac{2}{35}[/tex]
probability of picking two black balls one after other without replacement is 2/35.

;w; can someone please help me... i have tried asking these before and people just give me a really confusing or incomplete answer.. please dont answer if you dont know the answer, if there is gonna be any links in your answer and/or its just gonna be random letters and not a complete answer
Answer:
Level 2:
45 x 45 = 2025
28 x 28 = 784
2025 + 784 = 2809
(sqrt)2809 = 53
53 units
Level 3:
(Start by graphing the coordinates)
Your shape should have one leg of 14 units, and one leg of 8 units.
14 x 14 = 196
8 x 8 = 64
196 + 64 = 260
(sqrt)260 = 16.1245155
(rounded to nearest tenth)
16.1 units

To simplify, we multiply the like terms, which are the constant, and the s. For the constants of 1.5, and 3.5, we just do 1.5x3.5 to get 5.25, and when we multiply both s's together, we get [tex]s^2[/tex]. adding those 2 together, we get 5.25[tex]s^2[/tex]. so it would be the third one down.

calculate the Highest common factor of 130,260,390
the Highest common factor of 130,260,390 = 130
130 = 2⋅5⋅13
260 = 2⋅2⋅5⋅13
390 = 2⋅3⋅5⋅13
Common multipliers (130; 260; 390): 2, 5, 13
Now to find the highest Common factor you need to multiply the common factors
Answer: (130 ; 260 ; 390) = 2 ∙ 5 ∙ 13 = 130
Answer:
130
Step-by-step explanation:
130 = 2x5x13
260 = 2x2x5x13
390 = 2x3x5x13
common factors = 2, 5, 13
therefore, 2x5x13 = 130

Mackenzie was offered a job that paid a

salary was set to increase by 5% per year
every year. If Mackenzie worked at the job
for 17 years, what was the total amount of
money earned over the 17 years, to the
nearest whole number?
Answer:
103,140.82, or 103,141 since it asks for the whole number.
Step-by-step explanation:
[tex]45000(1.05)^17[/tex]
the 17 is supposed to be the whole power, not sure why the 7 is lower. but since she is making 45k a year, at a 5% increase in wages per year, this is how we would set up the equation. the number, multiplied by the percentage which is written as 1.05, since it is an increase, not a decrease, then we set that to the power of 17 since it is 17 years.
