Greg spent 6.4 hours working with his dad one Saturday. If his dad paid him$45.76, how much did Greg make per hour?
Answer:
$7.15
Step-by-step explanation:
The best way to solve this is by crossing out the data you don't need so you're left looking at the key pieces to put the equation together. If his dad paid him $45.76 for 6.4 hours, then all you need to do is divide 45.76 by 6.4. (Hint: Use a calculator, it makes it ten times faster than trying to write it out!)
45.76 ÷ 6.4 = 7.15
So Greg made $7.15 an hour working with his dad.

An item that cost $220 has been marked up by 15% since last year. However, a person can buy the item for a 25%
employee discount. How much will the employee pay?
Answer:189.75
Step-by-step explanation: 220 * 0.15 = 33
220 + 33 = 253
253 * 0.25 = 63.25
253 - 63.25 = 189.75

Suppose that 8 cards are drawn from a well-shuffled deck of 52 cards. What is the probability that all 8 are black? The probability is (Round to six decimal places as needed.)
Answer:
0.0020760077
Step-by-step explanation:
The probability of drawing the first black card is 26/52 because there are 26 of them in a deck of 52.
The probability of drawing the second black card is 25/51 because there are 25 of them in a deck of 51.
The probability of drawing the third black card is 24/50 because there are 24 of them in a deck of 50.
And so on and so forth, now we just have to multiply the 8 fractions together:
26/52*25/51*24/50*23/49*22/48*21/47*20/46*19/45=
[tex]\frac{26}{52} *\frac{25}{51} *\frac{24}{50}* \frac{23}{49} *\frac{22}{48} *\frac{21}{47} * \frac{20}{46} * \frac{19}{45}[/tex]= 0.0020760077
which is the equation of this best line of fit?
Answer:
D) y = 5x + 25
Step-by-step explanation:
the line of fit is defined by y = mx + b where:
m = the slope of the line (the rate of change)
b = the y-intercept (where it crosses the y-axis)
We see that for every 1 unit the graph moves horizontally... it moves 5 units vertically, thus we are given m = 5
If you look at the y-axis... we can determine that the graph crosses the y-axis at (0, 25), thus we are given b = 25
Therefore, the answer is y = 5x + 25
In a fourth grade class, four-sixths of the students are girls. If there are 20 girls, what is the total number of
students in the class?
students
Answer:
30 students.
Step-by-step explanation:
Since 20 girls make up 4/6 of the class, 1/6 of the class would be 5 students. 5*6=30, resulting in 30 students total.
Which inequality is equivalent to x/2+3 < 12?
0x<4.5
0x<9
Ox+6= 12

Answer:
x < 18
Step-by-step explanation:
just solve for x
subtract 3 from both sides
then multiply 2 to both sides
Can some one help me find x?
Answer:
x = 20
Step-by-step explanation:
Exterior angles are equal.
7x - 3 = 6x + 17
Add 3 and subtract 6x to both sides.
x = 20 is the answer.
Which equation has a constant of proportionality equal to 0.25
Choose 1 answer
What are the values of a and b?
Step-by-step explanation:
c.....................
Answer:
A
Step-by-step explanation:
Both triangles are similar triangles!
Length 21 for the top triangle is similar to length 20 for the bottom triangle
Length 29 for the top is similar to b on the bottom.
Length 20 for the top is similar to a on the bottom.
Use the first ratio: 21/20 to find the proportionality constant.
Divide 29 by that constant to get b
Divide 20 by that constant to get a
You end up with b = 580/21 (= 27.61), and a = 400/21 (= 19.047)
Therefore A is the right answer.

-;(1,1)
4
The equation is y =
Answer:
y=(5x-3)/4
y=(5/4)x-3/4
Perpendicular slops come from reversing the numerator and denominator and making it negative so the new slope would be:
m=-4/5
Then you use point slope formula and plug in your values:
y-y1=m(x-x1)
y-1=-4/5(x-1)
y=(-4/5)x+9/5

Factor the expression 42a+14b using the gcf
Please figure this out quickly
If you are trying to factor it is 14(3a+b).
But if you are looking for the greatest common factor it is 14.
The GCF of 42a + 14b is 14 which is 14(3a + b).
What is GCF?GCF stands for the greatest common factor of two or more two given terms. A number is GCF of two or more than two terms is the highest term that divides the given terms completely.
Given, 42a + 14b and we have to factor this with a GCF.
In terms of variables a and b, there is no common factor.
In terms of 14 and 42 GCF is 14 as 14 is the highest no. that divides these two nos. completely.
So, 42a + 14b.
= 14(3a + b).

A parabola can be drawn given a focus of (5, -7) and a directrix of x=1. Write the equation of the parabola in any form.
Answer:
x = 1/8(y^2 + 14y + 73)
Step-by-step explanation:
Take any point on the curve (x, y). This is a parabola that opens to the right and contains terms in x and y^2.
The distance of this point from the focus = its distance from the directrix, so:
sqrt [( x - 5)^2 + (y + 7)^2) = (x - 1)
Squaring both sides:
(x - 5)^2 + (y + 7)^2 = (x - 1)^2
x^2 -10x + 25 + y^2 + 14y + 49 = x^2 - 2x + 1
y^2 + 14y + 73 = 8x
x = 1/8(y^2 + 14y + 73)

Find the value of d such that the system of equations 15x + 10y=-11 and -9x+DT=-19
Answer:
1. 15x + 10y=-11
15x + 10y + 11=-11 + 11
15x + 10y + 11 = 0
2. -9x + DT = 19
-9x = 19 - DT
x = 19/9 + 1/9DT
x = 19/9 + 1/9DT, D∈ℝ, T∈ℝ
