Answer:

$8.90

Step-by-step explanation:

first you have to subtract how much money you get for overtime, 516.20-160.20=356.00 Next you have to divide 356.00 by 40 to find per hour, 356.00/40=8.90.

Answer:

Sydney is 21 years old

Step-by-step explanation:

1. subtract 11 from 53 (53-11=42)

2. divide the difference by 2 (42/2=21)

Answer:

x+11+x=53

2x+11=53

-11. -11

2x=42

x=21

Answer:

5×4+9

Step-by-step explanation:

The product of something means to multiply, so you would multiply 5 and 4 together.

Then you would add 9 to that.

Answer:

x=-3,1

Step-by-step explanation:

The roots (zeros) are the  

x

values where the graph intersects the x-axis. To find the roots (zeros), replace  

y

with  

0

and solve for  

x

.

Answer:

-8w=16

Step-by-step explanation:

-5w-9+9 = 3w+7+9

-5w=3w+16

-5w-3w=3w-3w+16

-8w=16

To solve:

-8w/-8=16/-8

w = -2

Answer:

x=11

Step-by-step explanation:

the angles shown are supplementary so they will add up to equal 180 so we write the equation 180=5x+10x+15 and solve for x

step 1 combine like terms

180=15x+15

step 2 subtract each side by 15

165=15x

step 3 divide each side by 15

x=11

c. a = 3√2, b = 6√2

#1.First, you find the opposite of the left triangle using sin formula

#2.After you get the opposite, find the b using sin formula and a using tan formula

•Right triangle

Hypotenuse = 6

Adjacent = ?

Opposite = ?

• Left triangle

Hypotenuse = b

Adjacent = a

Opposite = ?

a. adjacent of right triangle

b. hypothenuse of left triangle

#1. Sin(∅)= opposite/hypotenuse

sin(45) = opposite/6

opposite = sin(45) × 6

opposite = 3√2

#2. a. tan(∅) = opposite/adjacent

tan(30) = 3√2 / a

a = 3√2 : tan(30)

a = 3√6

b. sin(∅) = opposite/hypotenuse

sin(30) = 3√2 / b

b = 3√2 : sin(30)

b = 6√2

#and so the a = 3√2 and b = 6√2

Answer:

f(-3)=(-3)²-2(-3)=9--6=9+6=15

Answer:

15

Step-by-step explanation:

f(x)=x^2-2x

f(-3)=(-3)^2-2(-3)

f(-3)=9+6

f(-3)=15

Answer:

B, an = 4n - 9

Step-by-step explanation:

The sequence is for every time the exponent on a goes up one, the number that it equals to goes up by 4. So to find the nth term, we at 4 to n. I hope this helped! :)

===================================================

Work Shown:

The uppercase letters A,B,C are the angles, while the lowercase counterparts (a,b,c) are the sides opposite those angles. For instance, side b is opposite angle B.

We have this known info:

The ultimate goal is to find side BC, which is opposite angle A. So this is side a.

Now apply the law of sines to solve for 'a'.

sin(A)/a = sin(C)/c

sin(59)/a = sin(15)/10

10*sin(59) = a*sin(15)

a*sin(15) = 10*sin(59)

a = 10*sin(59)/sin(15)

a = 33.1184013279463

Make sure your calculator is in degree mode.

This rounds to the nearest tenth to get a = 33.1 which is the approximate length of side BC.

step 1 is wrong . The 1st step should be 15² - 9² = c² .

Answer: step A

Step-by-step explanation:

The Pythagorean theorem is a^2+b^2=c^2, where c is always the hypotenuse (the longest side of the triangle). Step A is written as 9^2(thats the a value squared)+15^2(which is the hypotenuse value squared)=c^2. It should be: 9^2+b^2=15^2

Answer/Step-by-step explanation:

Let x hours be the number of hours Issac worked

    x+6 hours be the number of hours Ruby worked

   4(x+6) hours be the number of hours Svetlana worked.

x + x + 6 + 4(x+6) = 126

x + x + 6 + 4x +24 = 126

                  6x +30 = 126

                         6x = 96

                           x = 16

Therefore, Issac worked 16 hours.

                 Ruby worked 16+6 = 22 hours

                 Svetlana worked 22 × 4 = 88 hours.

If helpful, please mark as brainliest! =)

Answer: Ruby: 22 hours, Isaac: 16 hours & Svetlana: 88 hours.

Step-by-step explanation:

Let's begin by assigning letters to represent our unknowns:

R (hours Ruby worked)

I (hours Isaac worked)

S (hours Svetlana worked)

Now let's see if we can express all three unknowns in terms of one unknown, according to the facts given in the problem:

R = I + 6 (Ruby worked 6 more hours than Isaac)

S = 4R (Svetlana worked 4 times more hours than Ruby)

We can see that we can express the hours Isaac worked in terms of Ruby:

R = I + 6, therefore, I = R - 6

Now we have all three unknowns expressed in terms of one unknown (R). Now we can write an equation to express the given sum of their worked hours (126) in terms of our expressions for one unknown (R):

R + (R - 6) + 4R =126

Now let's solve our equation for the value of R and then use our expressions for R to calculate the values for I and S:

R + R - 6 + 4R = 126

6R - 6 = 126

6R = 126 + 6

6R = 132

R = 132/6

R = 22 (hours Ruby worked)

I = R - 6

I = 22 - 6

I = 16 (hours Isaac worked)

S = 4R

S = 4(22)

S = 88 (hours Svetlana worked)

Answer:

10-3y=12

or, -3y=12-10

or, -3y=2

or, y= 2/(-3)

or, y= -(2/3)

Answer: 3, 37

Step-by-step explanation:

Divide by 3, divide by 3 again. 37 is a prime number, so it can't be divided again after that.
