The table that shows the relationship between h, the number of hours John’s brother works, and c, the total cost of the project is third table.
What is multiplication?Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.
Example - 2 × 3 means 2 is added three times or 3 is added 2 times.
Given that John paid $485 to build a deck.
And he will pay $25 per hour to his brother for building the deck.
one hour of work costs John $25 + $485 .
Total cost of building deck = $25 × h number of hours + $485
3 hour of work costs $25 × 3 = $75 + $485 = $560
8 hour of work costs = $25 × 8 = $200 + $485 = $685
12 hour of work costs = $25 × 12 = $300 + $485 = $785
Therefore, the third table suggests the total cost of work.

Solve for a. ab+ c =d
Answer:
[tex]\frac{-c+d}{b}[/tex]
Step by Step:
Step 1: Subtract c from both sides:
ab + c + (−c) = d + (−c)
ab = −c + d
Step 2: Divide both sides by b:
[tex]\frac{ab}{b} = \frac{-c+d}{b}[/tex]
Step 3: Simplify:

he curb weight of a new car is 3,347 pounds. How much does the car weigh?
Answer:
Step-by-step explanation:
I think it is 3,347. Because the curb weight is just the car without humans
Given that the curb weight of a new car is = 3347 pounds
Now we have to find the correct choice for the given weight of the car.
Given value is in pound while the choices are in ton.
Units are different so first task will be to get same units.
We know that 1 ton = 2000 pound
so to convert 3347 pound into ton, we will divide 3347 by 2000 and get 1.6735 ton.
Which lies between 1 and 2.
Hence final answer will be (c) between 1 and 2 tons.

a cyclic quadrilateral is shown. x:y=3:7. work out the size of angle z
Step-by-step explanation:
x:y=3:7
x+y=180
3+7=10
180/10=18
to find x
18*3=54
x+10+z=180
54+10+z=180
64+z=180
z=180-64
z=116°
The measure of angle z of the cyclic quadrilateral will be 116 degrees.
What is a cyclic quadrilateral?If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral.
A cyclic quadrilateral is shown.
x / y = 3 / 7
y = 7x / 3
We know that the sum of the opposite angles of the cyclic quadrilateral is 180 degrees. Then the equation will be
x + y = 180°
x + 7x/3 = 180°
10x/3 = 180°
x = 54°
Then another equation is given as,
x + 10° + z = 180°
54° + 10° + z = 180°
z = 116°
The measure of angle z of the cyclic quadrilateral will be 116 degrees.

Find the distance between the complex numbers. z1 = 9 - 9i z2 = 10 - 9i
Answer:
The distance between the two given complex numbers = 9
Step-by-step explanation:
Explanation:-
Step(i):-
Given Z₁ = 9 - 9 i and Z₂ = 10 -9 i
Let A and B represent complex numbers Z₁ and Z₂ respectively on the argand plane
⇒ A = Z₁ = x₁ +i y₁ = 9 - 9 i and
B = Z₂ = x₂+ i y₂ = 10 -9 i
Let (x₁ , y₁) = ( 9, -9)
(x₂, y₂) = (10, -9)
Step(ii):-
The distance between the two points are
A B = [tex]\sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2} }[/tex]
A B = [tex]\sqrt{(10 - 1)^{2}+(-9 - (-9))^{2} }[/tex]
AB = [tex]\sqrt{(9)^{2} +(-9+9)^{2} }[/tex]
AB = √81 = 9

each. Xavier worked the first shift. During Jeanine's shift, she sold 8 tickets. At the end
of the day, the total amount of money from tickets sold was $240. Which equation could
be used to determine x, the number of tickets Xavier sold ?
A. 12(X + 8) = 240
B. X(12 + 8) = 240
C. 12 + 8x = 240
D. 12x + 8 = 240
Answer: 12(X+8)=240
Step-by-step explanation: We then would have to do the distributive property and you end with 12x+96=240
Subtract 96 from each side
Then you end with
12x=144
You then divide 12 from each side and see that X=12!

What is the x-intercept of f-^1(x)?
Answer:
(2 1/2, 0)
Step-by-step explanation:
In the picture attached, the complete question is shown.
f(x) = 2 1/2 - 3 1/3 * x
or
f(x) = 5/2 - (10/3)*x
f^-1(x) is the inverse of f(x), which is obtained replacing f(x) by x, and x by y, and solving for y, as follows:
x = 5/2 - (10/3)*y
(10/3)*y = 5/2 - x
y = (5/2)*(3/10) - x*(3/10)
y = (3/4) - (3/10)*x
f^-1(x) = (3/4) - (3/10)*x
at x-intercept, f^-1(x) = 0,
(3/4) - (3/10)*x = 0
(3/4) = (3/10)*x
x = (3/4)*(10/3)
x = 5/2 or 2 1/2

Your mom is taking you shopping at the mall. She has $78 to spend on you. You already know that $18 of that money is for your school backpack. You need to get 2 shirts and 2 pairs of pants for your school uniform. The pants and the shirts cost the same amount for each. How much does each shirt or pair of pants cost?
Answer:
each coat $15
Step-by-step explanation:
$78-$18 divided by 4 =15
hope this helps :)
Answer:
The answer is that each shirt and pair of pants costs 15$
Step-by-step explanation:
So you have 78$, and you already need to buy a backpack so then you have 60$ dollars because the backpack is 18$, and 2 shirts and 2 pairs of pants is 4 pieces of clothing in all, 60$ divided by 4 pieces of clothing equals 15$ per piece of clothing (78 - 18 = 60 divided by 4 = 15)

Answer:
Angle 2, angle 3 and angle 4 will measure 60°
Step-by-step explanation:
From the figure attached,
'l' and 'm' are parallel lines and 't' is the transverse line.
m∠1 = m∠2 = 60° [Vertical angles]
m∠1 = m∠3 = 60° [Corresponding angles]
m∠1 = m∠4 = 60° [Alternate exterior angles]
Therefore, angle 2, angle 3 and angle 4 will measure the same as angle 1.
Explain how you can solve the following scenario in two different ways. I owe my friend $16 and my mom owes me $25. how much money will I have after all is settled?
Answer:
$9
Step-by-step explanation:
Given I owe my friend $16 and my mom owes me $25
step 1-->take back money from mom
Mom gives back you $25
Now you have $25
Step 2: return the money you owe to friend
you owe $16
You have $25 and return $16
Thus , money you will have = money you have - money you return
money you have = $25 - $16 = $9
Thus, you will have $9 , after all is settled.

One tool used in genetics is called a pedigree chart,are there any advantages to using this tool?The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an exponential growth function to model this situation. Then find the population in 2009.
Answer:
A = 236,000 (1.04)^t
population in 2009 : 335,902 people
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form) = 4/100 = 0.04
t= years passed from 2000
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04)^t
A = 236,000 (1.04)^t
Population in 2009.
t = 2009-2000 = 9
A = 236,000 (1.04)^9
A = 335,902 people
