Answer:
7 hours
Step-by-step explanation:
$247.50 - $45.00 (how much he charges for the first hour) = $202.50
$202.50 ÷ $33.75 (how much he charges for the additional hours) = 6 hours
But he charges 45 dollars for the first hour so he 7 hours in total

Construct a line through R that is perpendicular to the line
Answer: just did it 3 secs. ago
Step-by-step explanation:
The answer is shown below.
Perpendicular:In simple geometry, two geometric objects cross at a right angle ( [tex]90^{0}[/tex]degrees or [tex]\frac{\pi }{2}[/tex] radians ) if they are perpendicular to one another.If two lines cross at a right angle, they are said to be perpendicular to one another. A first line is explicitly said to be perpendicular to a second line if the two lines meet and the straight angle on one side of the first line is cut by the second line into two congruent angles at the point of junction.Therefore, the Construction of a line through R that is perpendicular to the line is shown below:

Step-by-step explanation:
assuming AB = DE and angle F = angle C,
set 4x - 6 = 10", solve for x...
4x = 4, x = 1
set 14x + y = 60°, substitute 1 for x then solve for y...

Answer:
f(-2) = -5
f(0) = 5
f(1) = 10
Step-by-step explanation:
f(-2) = 5(-2) + 5 → -10 + 5 = -5

f(1) = 5(1) + 5 → 5 + 5 = 10
POLYNOMIALS QUESTION!!!
Answer:
The new area of the smaller rectangle is 16 - x² units²
Step-by-step explanation:
The dimensions of the small rectangles are 2 + x and 2 - x
∵ The length of the small rectangle is 2 + x units
∵ The length is adding by 2 units
∴ The new length = 2 + x + 2 = 4 + x units
∵ The width of the small rectangle is 2 - x units
∵ The width is adding by 2 units
∴ The new width = 2 - x + 2 = 4 - x units
∵ Area of the rectangle = length × width
∴ The new area of the smaller rectangle = (4 + x) × (4 - x)
→ Simplify it by multiplying the 2 brackets
∵ (4 + x)(4 - x) = (4)(4) + (4)(-x) + (x)(4) + x(-x)
∴ (4 + x)(4 - x) = 16 + (-4x) + 4x + (-x²)
→ Remember (+)(-) = (-)
∴ (4 + x)(4 - x) = 16 - 4x + 4x - x²
→ Add the like terms
∴ (4 + x)(4 - x) = 16 - x²
∴ The new area of the smaller rectangle is 16 - x² units²

Mark starts a rock climb when he is 1 mile above sea level. He can climb at the rate of 1.5 miles per hour. Which of the following functions would express Mark's height above sea level over time?
A. f( x) = 1.5 x
B. f( x) = 2.5 x
C. f( x) = 1 + 1.5 x
Answer:
C.
Step-by-step explanation:
Its C because you start out at 1 mile above sea level, then each time Mark climbs he goes up 1.5 miles per hour. f(x)= 1(starting point) + 1.15x (miles per hour).

which form most quickly reveals the vertex?
choose 1 answer:
a. g(x)=-2x^2-16x-14
b. g(x)=-2(x+4)^2+18
c. g(x)=-2(x+1)(x+7)
what is the vertex?
vertext= (___,___)
Answer:
The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18 ⇒ b
The vertex = (-4, 18)
Step-by-step explanation:
The vertex form of the quadratic function f(x) is:
f(x) = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointThe most quickly reveals to find the vertex is the vertex form above
Look at the answer and try to find a similar form to the vertex form above
∵ g(x) = -2(x + 4)² + 18
∴ a = -2
∴ h = -4
∴ k = 18
⇒ That means this form is similar to the form above
∴ The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18
∴ The vertex = (-4, 18)

Jeremiah dad Ordered five large pepperoni pizzas in each large cheese pizzas for the birthday party he spent a total of 144 on pizza if a pepperoni pizza cost 12 right and solve a linear equation to find the cost of a cheese pizza
This question is incomplete because part of the information is missing; here is the complete question:
Jeremiah's dad ordered 5 large pepperoni pizzas and 8 large cheese pizzas for the birthday party. He spent a total of $144 on pizza. If a pepperoni pizza costs $12, write and solve a linear equation to find the cost of a cheese pizza.
The answer to this question is $10.50
Explanation:
The first step to solve this problem is to write a linear equation. In this, the unknown should be represented by an x, and other variables should be included using correct mathematical symbols. Here is the process:
1. In an equation there is always an equality symbol = and mathematical expressions on both sides.
2. In this situation, the value after the = symbol should be 144 or the total spend on pizzas.
3. The values missing should be expressed as 5 (12) + 8x because there are 5 pepperoni pizzas and each of these costs $12; also, this should be added to the 8 cheese pizza and x represents the missing value (the price of a cheese pizza.)
4. Solve the equation
5 (12) + 8x = 144 -Simplify using multiplication
60 + 8x = 144 - Solve by moving the number to the right side and changing the symbol
8x = 144 - 60
8x = 84
x = 84 ÷ 8
x = 10.5

Naomi is planning a holiday. The hotel costs $80 every night she stays and the flight costs $250,
She has a budget of $700 for her hotel and flight. How many nights will she be able to stay at
the hotel without going over her budget?
Answer:
5 nights
Step-by-step explanation:
# of nights= budget - flight {divided by} price per night
= 700$ - 250$ {divided by} 80$
= 450$ {divided by} 80$
= 5.6
=5 (round down)
Answer:
she will be able to stay 5 nights at the hotel
the second awnser and the third awnser.
Step-by-step explanation:
if the flight costs $250 and a night at the hotel costs $80 then 5 nights would equal $400 and then you would add the flight costs and it would equal $650. it can't be 6 nights cause she would go over her budget.

Answer:

Step-by-step explanation:
1/3 of 24 is 8, and 1/4 is 6. 8+6=14, and 24-14=10. So I think that 10 people brought chips.
Answer:
10
Step-by-step explanation:
24 ÷ 3 = 8 so one third is 8
24 ÷ 4 = 6 so one fourth is 6
8 + 6 = 14 (14 people brought drinks or dessert)
24 - 14 = 10
ten people brought chips.

A line has a slope of
1/4
and passes through the point (0.2,
4/5
Find the value of b, the y-intercept.
b = ???
Answer:
b = 3/4
Step-by-step explanation:
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → 3/4
b = 3/4
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → 3/4
