Answer:
a) 5m
b) $26.25
Step-by-step explanation:
You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food.
a) Write an algebraic expression for the total amount of money contributed for money?
Let the total Amount of money each person contributed be = m
Since each person contributed the same amount , and there are 5 people(you and 4 friends)
The total amount of money contributed = 5 × m
= 5m
b) Evaluate you expression if each person get $5.25
From the answer in question a, we have algebraic expression = 5m
m = $5.25
Total cost = 5 × $5.25
= $26.25

Amy and Roger both wash windows at a large downtown building. Amy can wash 25 windows In 4 hours, Roger can wash 32 windows in 6 hours. How many windows can they wash together in 12 hours? [Type your answer as a number.)
Answer:
139 windows
Step-by-step explanation:
you multiply the 25 by 3 because Amy washes 25 windows per 4 hours and 3x4 is 12 so that would be 75 then you multiply the 32 by 2 because 6x2 is 12 so that would be 64 then you add the 64 and 75 which would give you 139 windows for both of them in 12 hours
the equation y=2x-1 is the boundary line for the inequality y>2x-1. which sentence describes the graph of the inequality?
A: the region shaded above a dashed boundary line
b: the region shaded above a solid boundary line
c: the region shaded below a solid boundary line
d: the region shaded below a dashed line
Answer: A
Step-by-step explanation:
The region shaded above a solid boundary line is considered. Then the correct option is B.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The line is given below.
y = 2x - 1
y > 2x - 1
Combine the equations. Then we have
y ≥ 2x - 1
The graph of the line is given below.
The region shaded above a solid boundary line is considered. Then the correct option is B.

b. (-0.4, 6.8)
d. (-0.4, 5.2)
Answer: (-0.4, 6.8)
The graph is attached
Step-by-step explanation:
We can find the axis of symmetry using the formula x = -b/2a
x = - -4/2(-5)
x = 4/-10
x = 0.04
Substitute for x and calculate y
y = [tex]\left(0.4^{2}\right)\left(-5\right)-4\left(-0.4\right)\ +6[/tex]

Find the area of all shaded regions. Give your answer as a completely simplified exact value in terms of pi. (no approximations)
To find the area of the shaded region, you first use the equation A = πr²
The radius of the circle is 9 cm. So A = π(9²)
A = 3.14 (81)
A = 254.34 (entire circle)
The entire circle is 360°
and 4.5 of the 80°'s will equal 360°
254.34 ÷ 4.5 = 56.52
ANSWER: 56.52 cm²
Answer:
56.55 cm^2
Step-by-step explanation:
Since a circle is 360 degrees and the piece is 80 degrees, the shaded area is 4.5 of the total area of the circle (9/2). Find the area of the circle:
[tex]\pi r^{2}[/tex]
[tex]\pi 9^{2}[/tex]
[tex]\pi 81[/tex]
[tex]254.47/4.5[/tex]
56.55 cm^2
s is inversely proportional to t . When s = 0.6 , t = 5 Work out s when t = 0.3
Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s = [tex]\frac{k}{t}[/tex] ← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )
3 = k
s = [tex]\frac{3}{t}[/tex] ← equation of proportion
When t = 0.3, then
s = [tex]\frac{3}{0.3}[/tex] = 10

A skating rink sold tickets for Friday Night's show. Of the 66 tickets sold 2/3 were adult tickets and 1/3 were children's tickets. What is the total number of adult tickets sold?
The number of aduir tickets sold was 44. If 2/3 of the ticket is 66 and 1/3 of the tickets is 1/3, you’ll know that by diving 66 with 3 you find the answer for the children’s ticket. 66 divide 3 is 22. But how do you find the adults ticket? Well if the rest are all adults which it is then you find the left overs. 66-22=44 and the answer will be 44. 1/3 of 66 is 22 and 2/3 of 66 is 44.

Consider the line with a slope of -1 through the point (-1,3).What is the y-intercept (b) of the line
Answer:
y = -x + 2
Step-by-step explanation:
slope = -1 ; (-1 , 3)
Equation: y - y1 = m (x - x1)
y - 3 = (-1)(x -[-1])
y - 3 = (-1) (x + 1)
y - 3 = -x - 1
y = -x - 1 + 3
y = -x + 2
