Answer:
1) a≥−2.5
2) n<1.2
3) b≥−0.8
4) false,
5) r≤0.1
6) y≤0.8
Step-by-step explanation:
1) Divide both sides by -3.2.
−3.2a/-3.2 ≤ 8/-3.2
2) Flip the equation
- n+0.8<2
Subtract 0.8 from the sides
n+0.8−0.8<2−0.8
3) Add 4.2 to both sides.
b−4.2+4.2≥−5+4.2
4) inequality cannot be solved
5) Simplify both sides of the inequality.
−r+5.1≥5
Subtract 5.1 from both sides.
−r+5.1−5.1≥5−5.1
−r≥−0.1
Divide both sides by -1.
-r/-1 ≥ -0.1/-1
6) Flip the equation.
−1.8y≥−1.44
Divide both sides by -1.8.
−1.8y/−1.8 ≥ −1.44/−1.8
good luck with your work!!

Answer:
b) The slope of line is 20
c) The equation in slope-intercept form is: [tex]\mathbf{y=20x}[/tex]
d) i) she would have travelled 1480 m after 74 s
ii) It will take 125 s to travel 2.5 km
Step-by-step explanation:
Part b: Slope of Line
Slope of line can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table we can take any two points and find the slope.
Looking at the graph, the time is x-axis and distance is y-axis
Let we take (0,0) and (8,160)
So, we have: [tex]x_1=0, y_1=0, x_2=8, y_2=160[/tex]
Now finding Slope:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{160-0}{8-0} \\Slope=\frac{160}{8}\\Slope=20[/tex]
So, the slope of line is 20
Part c) Find the equation in slope-intercept form
The general equation of slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept
We have found slope, m = 20
We need to find y-intercept.
y-intercept can be found by putting x-axis (time) equal to zero and check what the y-axis (distance) is:
So, when x =0, y=0
So, y-intercept = 0
The equation will be:
[tex]y=mx+b\\y=20x+0\\y=20x[/tex]
The equation in slope-intercept form is: [tex]\mathbf{y=20x}[/tex]
Part d)
Part i) How far will she have travelled after 74 s
We are given time (x) = 74 s
We need to find distance i.e. y:
Using the equation: [tex]\mathbf{y=20x}[/tex]
Put x = 74
[tex]y=20x\\y=20(74)\\y=1480[/tex]
So, she would have travelled 1480 m after 74 s
Part ii) How long will it take to travel 2.5 km
We are given distance (y) = 2.5 km
We need to find time i.e. x:
Using the equation: [tex]\mathbf{y=20x}[/tex]
Since distance is given in meters but here it is in km
So converting 2.5 km into m
We know that 1 km = 1000m
So, 2.5 km = 2500 m
Now finding time:
[tex]y=20x\\2500=20(x)\\x=\frac{2500}{20}\\x=125[/tex]
So, It will take 125 s to travel 2.5 km

Step-by-step explanation:
The lights go out, your bedroom is pitch dark, yet you still need to find a pair of socks, in your drawer there is 25 white socks and 25 red socks how many socks do you need to pull out before you get a matching pair?
Answers
Answer: At most 3
Step-by-step explanation:
If there are 25 white socks and 25 red socks, a matching pair would be picked in at most 3 times.
The first sock you pick would be either White or Red
The second sock you pick would be either white or red again which means that you now either have 2 whites, 2 reds or 1 white and 1 red.
The third sock you pick will either be white or red once more. At this point you will either have 3 whites, 3 reds, 2 whites and 1 red or 2 reds and 1 white.
You will therefore have at least a matching pair after 3 tries.

Martin is helping his mom set up for a school event. His mom put 150 cups into a box. There are 40 red cups, 60 blue cups, and
50 green cups in the box. He randomly picks 90 cups from the box and sets them out on tables.
How many blue cups is he likely to have set out on tables?
Answers
Answer:
C. 36
There are 150 cups total, and 60 blue cups

Solve the following system of equations:
y=2x + 1
y = -x+4
x= ?
y=?
Answers
Answer:
x= 1, y=3
Step-by-step explanation:
y= 2x +1
y= -x +4
Those two equation are in a system that means they need to be true in the same time. Just like I would say look for a car that is red and is a truck in this case we look for x and y is true that y = 2x+1 and is true that y= =x+4.
so y= 2x+1 but y is -x+4 so substitute
-x+4 = 2x +1, add x on both sides
4= 2x+x +1, subtract 1 from both sides
4-1 = 2x +x, combine like terms
3 = 3x , divide both sides by 3
x=1
if x=1 we substitute in y= -1 +4 = 3

Answers
Answer:
The measure of Angle B = 82
Step-by-step explanation:
⁕We have to calculate the angle for A.
‣Notice how angles A is on a straight angle, a straight angle equals 180 degrees by the way.
⁕You are going to subtract 143 from 180.
[tex]180 - 143 = 37[/tex]
‣So the angle of A is 37. A triangle equals 180 degrees.
⁕You are going to combine angle A and Angle C and subtract it from 180, to find angle B.
[tex]61 + 37 = 98 \\ 180 - 98 = 82[/tex]
‣Therefore, angle B equals 82.

The choir needs to raise $2,620.00 for a trip to the state competition. They are selling sets of candles for $25.00 per set. They have already raised $1,225.00 from the fundraiser.
The band needs to raise $2,400.00 to pay for a trip to the state capital to participate in a parade. They are selling 3-gallon tubs of caramel popcorn for $18.25 each. They have already raised $1,314.00 from the fundraiser.
Answers
Answer:
1086/18.25 = 59.51
60 more tubs of popcorn to reach their target.
Step-by-step explanation:
OK, here we go. Golf Club first
You subtract the total amount they need to raise, by the amount they already have:
2620 - 1225 = $1395.00 to go
Divide that number by the price of golf balls to find out how many more they need:
1395/25 = 55.8
This means that they need to sell at least 56 golf balls to meet the target.
Now to the Percussion Club...
Do the same thing again:
2400 - 1314 = $1086 to go
1086/18.25 = 59.51
So the percussion club needs to sell at lest 60 more tubs of popcorn to reach their target.
Arisia puts $500 into a savings account with an annual simple interest rate of 4.5%. If the savings account pays 5% simple interest, how much interest will Arisia earn on her $500 principal over 20 years?
Answers
Answer:
$500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 500 × 0.05 × 20 = 500
I = $ 500.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 5% per year
for 20 years is $ 500.00.
