For the first week of January, Kim Walker worked 45.25 hours. Kim earns 10.90 an hour. Her employer pays overtime for all hours worked in excess of 40 hours per week and pays 1.5 times the hourly rate for overtime hours.
Answer:
Gross pay when she works 46 hours a week = 532 dollars per week
Step-by-step explanation:
Complete question
Find gross pay when she works 46 hours a week
Solution
For working hours less than or equal to 40 hours, kim earns 10.90 per hour
For working hours higher than the basic 40 hours of working, the per hour rate increases by 1.5 time = 1.5 *10.90 = 16 dollars per hour
Gross pay for 46 working hours = 40 *10.90 + 6*16 = 532 dollars per week

Answer:
The height of the square pyramid is 9.8 in.
Step-by-step explanation:
Given;
area of the square pyramid, A = 96 in²
base length, a = 4 in
height of the pyramid, h = x in
The surface area of the pyramid is calculated as follows;
[tex]SA = a^2 + 2a \sqrt{\frac{a^2}{4} + h^2} \\\\96 = 4^2 + 2(4)\sqrt{\frac{4^2}{4}+ x^2} \\\\96 = 16 + 8\sqrt{4+ x^2} \\\\96-16 = 8\sqrt{4+ x^2}\\\\80 = 8\sqrt{4+ x^2}\\\\\frac{80}{8} = \sqrt{4+ x^2}\\\\10 =\sqrt{4+ x^2}\\\\ (10)^2 = 4+ x^2\\\\100 = 4 + x^2\\\\ x^2 = 100-4\\\\x^2 = 96\\\\x = \sqrt{96} \\\\x = 9.80 \ in[/tex]
Therefore, the height of the square pyramid is 9.8 in.

Answer:
6 cm
Step-by-step explanation:
Well let me explain... It's saying that side AB has a length of 6 cm and side BC has a length of 10 cm. So we can already start labeling the sides with their given length and actually solve for AC.
Well we don't really got much to say about AC but what we do know is that side AB and AC are equivalent. Why? Cause when there's always a triangle that has two equal sides but one side bigger, the triangle is a isosceles.
So we can say that side AB is (Δ) from the top of the triangle all the way to the left corner (6 cm). Then side BC will be from the left corner to the right corner (10 cm) and side AC will be from the top to the right corner (6 cm).

Find the lateral area and surface area of a cone with a radius of 12 and a height of 21
Answer:
The Lateral Surface Area is 911.32 square unit and
Total Surface Area is 1361.7 square unit.
Step-by-step explanation:
For a given Cone
Radius (r) = 12
Height (h) = 21
For Lateral Surface Area
Formula:A = πr√r² + h²
A = 3.14 × 12 × √(12)² + (21)²
A = 3.14 × 12 × √144 + 441
A = 3.14 × 12 × √585
A = 37.68 × 24.18
A = 911.32 square unit
Now,
For Total Surface Area
Formula:A = πrl + πr²
For Slant height (l)
l² = r² + h²
l² = (12)² + (21)²
l² = 144 + 441
l² = 585
l = 24.18
So,
A = πrl + πr²
A = πr(l + r)
A = 3.14 × 12 × (24.14 + 12)
A = 3.14 × 12 × 36.14
A = 1361.7 square unit
Thus, The Lateral Surface Area is 911.32 square unit and Total Surface Area is 1361.7 square unit.

Can I have the slope and y intercept for 2y - 4x - 10 =0
Answer:
Slope = 2, Y-intercept = (0, 5)
Step-by-step explanation:
First, isolate y by moving all other terms to the other side of the equation.
2y - 4x - 10 = 0 ⇒ 2y = 4x + 10 ⇒ y = 2x + 5
The coefficient next to the x tells you the slope and the constant on the end tells you the y-intercept.
Therefore, the slope is 2 and the y-intercept is (0, 5).
Answer:
slope=2 ,y-intercept=5
Step-by-step explanation:
2y-4x-10=0
2y=4x+10+0
2y=4x+10 . divide both sides by 2
y=2x+5

Which line is perpendicular to 4y+3x=12?
A)3x+4y=8
B)y=-3x+8
C)y+4x=-3
D)8x-6y=18
Answer:
D) 8x - 6y = 18
Step-by-step explanation:
The general equation of a line is;
y = mx + c
m is the slope and c is the y-intercept
so for;
4y + 3x = 12
4y = -3x + 12
divide through by 4
y = -3/4x + 3
the slope here is -3/4
To get the other line, we divide -1 by the slope of the first line
This is because when two lines are perpendicular, the product of their slopes is -1
So the slope of the line we are looking for is -1 divide by -3/4 = 4/3
Let us take a look at option D
8x - 6y = 18
6y = 8x - 18
divide through by 2
3y = 4x - 9
divide through by 3
y = 4/3(x) - 3
So as we can see, we have our slope as 4/3 and this option is our answer

Please explain!
Answer:
[tex]a_4=-1271[/tex]
Step-by-step explanation:
We are given that:
[tex]a_1=10[/tex]
And:
[tex]a_{n+1}=-5a_n-1[/tex]
And we want to find:
[tex]a_4[/tex]
This is a recursive formula. So we can simply substitute in each value. For instance, a₂ will be:
[tex]a_2=a_{(1)+1}=-5a_{1}-1=-5(10)-1=-51[/tex]
Thus, a₃ will be:
[tex]a_3=a_{(2)+1}=-5a_2-1=-5(-51)-1=254[/tex]
Finally, a₄ will be:
[tex]a_4=a_{(3)+1}=-5a_3-1=-5(254)-1=-1271[/tex]
What is the probability that a group of five friends all have different birthdays? Show all of your work for full credit.
Answer: 0.98630136986
Step-by-step explanation:
There are 365 possible birthdays. The key to assigning the probability is to think in terms of complements: “Two (or more) people share a birthday” is the complement of “All people in the group have different birthdays.” Each probability is 1 minus the other. What is the probability that any two people have different birthdays? The first person could have any birthday (p = 365÷365 = 1), and the second person could then have any of the other 364 birthdays (p = 364÷365). Multiply those two and you have about 0.9973 as the probability that any two people have different birthdays, or 1−0.9973 = 0.0027 as the probability that they have the same birthday. If you have a group of five, it would mean your equation would have to be (p=360÷365)

B. y = -4/3x + 22Step-by-step explanation:
Parallel lines have the same slope.
Use the given point (6, 14) and point-slope form:
y - 14 = -4/3(x - 6)y = -4/3x + 8 + 14y = -4/3x + 22Correct choice is B
Answer:
Solution given:
y=-4/3×x-1.......(1)
comparing above equation with y=mx+c
slope of line 1 is
m=-4/3
since the another line is parallel
slope is equal
m=m1=-4/3.
since it passes through (6,14)
we have
equation of a line is:
(y-y1)=m1(x-x1)
(y-14)=-4/3(x-6)
y=-4/3×x+4/3×6+14
y=-4/3×x+8+14
y=-4/3×x+22.
your option is b.y=-4/3×x+22.
