Answer:
0.45 x 60 = 27
35% x 60 = 21
27-21 = 6 more students prefer math
However, a further 12 students didn't specify whether they prefer maths or science, so you could argue that the answer is 6 +/- 12

Use the quadratic formula on your calculator.
on a certain Home Mortgage, there is a monthly payment of $9.43 for every $1,000 that is borrowed. What is the monthly payment on this type of loan if $135,000 is borrowed? NO LINKS!!!
Work Shown:
x/(135,000) = (9.43)/(1000)
x = 135,000*(9.43/1000)
x = 1273.05
Solve using ratios as ratios remain same
Let the amount be n
[tex]\\ \rm\Rrightarrow \dfrac{9.43}{1000}=\dfrac{n}{135000}[/tex]
[tex]\\ \rm\Rrightarrow 0.00943=n/135000[/tex]
[tex]\\ \rm\Rrightarrow n=0.00943(135000)[/tex]
[tex]\\ \rm\Rrightarrow n=1273.05[/tex]

What is the net decimal equivalent if 40%, 30% and 15% discounts were applied
Answer:
Well you can’t really stack these percentages discounts.
Assuming it’s in the same order as the problem then
We can find the decimal equivalent by just dividing.
So think of it like this way.
Your getting 40 percent off, the original price.
The original price of course is a 100 percent since its the one and only price.
When your taking 0.4 percent off then its taking off 0.4 from the 1.00
So you have 0.6.
Your now paying 60 percent of the price.
Now the 30 percent.
Same thing except this times its 0.6.
Now 30 percent of 60 is 18 percent and then subtract that by 0.6 which is 0.42
Now for the final 15 percent
Same thing except this time its 0.15
15 percent of 0.42 is 6.3 percent, subtract that by 0.42 is 0.357
After the discounts were applied you’d only have to pay 0.357 or 35.7%
In order to find the total amount of discounts just subtract the amount we have to pay by the original which was 100 %. 100 - 35.7 = 64.3
Final net percentage is equivalent 64.3%

Find the area of the figure. (Sides meet at right angles.)
2 ft
2 ft
5 ft
ft
8 ft
Bft
4 ft
8 ft
Answer:
44ft
Step-by-step explanation:
To find the answer, you need to first break down your shape. We can see that the 2 sides are identical so we can just multiply the area of on eof the sides by 2. The 2 sides equal 20 in all. Now lets look at the last section. To find an unknown side, we need to subract the 2 known sides. 8-5=3. 3x8=24
24+20=44
Hope this helps.
Answer:
44 ft²Step-by-step explanation:
A1 = 2(5 x 2) = 20
A2 = 8 x 3 = 24
total = 20 + 24
= 44 ft²
- Find distance around three-fourths of a circle with radius of 6 feet.
Step-By-Step Explanation:
1st Step : First lets take 6 times the circumference (Pi)
6 * 3.14 = 18.84
2nd Step : Next, Divide 18.84 by 4
18.84 /4 = 4.71
3rd Step : And lastly, Take 4.71 times 3.
3 * 4.71 = 14.13

If 50 percent of Q is 20 percent of P, then P is what percent of Q
Answer:
P is 250% of Q
Step-by-step explanation:
50/100 Q = 20/100P Multiply both sides by 100
50Q = 20 P Divide by 20
50/20 Q = P
2.5 Q = P
So P is 2.5 times the size of Q.
2.5 as a percent is 250 %

Which of these is the equation of a line with y-intercept (0,2) and slope 1/3
Answer: A
Step-by-step explanation:
The answer to this question is A. We know this because it is in slope-intercept form, there m is the slope and b is the y-intercept. In A, you can see that 1/3 is m and b is 2. This proves that A is the correct answer.

18POINTS!
6(3p – 2) = 24
Answer:
p= 2
Step-by-step explanation:
So first you want to distribute the 6 to 3p-2 which basically means multiply
6(3p – 2) = 24
6 times 3p is 18 and 6 time -2 is -12
* remember a negative and a positive equal a negative*
18p-12=24
you want to get 18p by itself, so in order to do that you can add 12 to both sides because if you add 12 on the left side it cancels out -12 and whatever you do to one side you have to do it to the other so add 12 to 24 which is 36
18p = 36
since you want to get p by itself you divide p on both sides so it can cancel out 18 and 36/18 is 2
so p = 2
if you are wondering why i divide it and not subtract or add it is because 18 and p are stuck together so you have to divide but if it was like 18 + p you can subtract because 18 and p arent together

PLEASE HELP
Answer: x-intercept = 42/3 = 14
Step-by-step explanation: y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
Notice that when x = 0 the value of y is 6/-1 so this line "cuts" the y axis at y=-6.00000
y-intercept = 42/-7 = 6/-1 = -6.00000
When y = 0 the value of x is 14/1 Our line therefore "cuts" the x axis at x=14.00000
x-intercept = 42/3 = 14
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -5.143. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.143 - (-6.000) = 0.857 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.857/2.000 = 0.429
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3x-7y-42 = 0 and calculate its properties
x-intercept = 42/3 = 14

Answer:
a) x + 8 ≥ 6
Step-by-step explanation:
x + 8 ≥ 6
Step 1: Subtract 8 from both sides
x + 8 - 8 ≥ 6 - 8
Step 2: Simplify
x ≥ -2
And since the symbol is greater than, we use a closed circle. Also, since the inequality is like an arrow pointing to the right, we draw the arrow going to the right.
Here are what the inequality symbols mean:
> = Greater than
≥ = Greater than or equal to
< = Less than
≤ = Less than or equal to
Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).
Do these ratios form a proportion?
$30 per 46 pounds
$15 per 23 pounds
Yes or No
Particularly yes
Step-by-step explanation:
$30 per 46 and 30÷ 2 is 15 while 46÷2 is 23
therefore it is yes

Answer:
A. Yes -- Aricka drew the line correctly because the line is decreasing with data points above and below the trend line.
Explanation:
This is what is known as having a line of best fit. The data points should at least nearly be evenly distributed on both sides of the line for it to be a good line of best fit. You should also make sure that you have at least a few points TOUCHING the line. This is a majour part of having a line of best fit.

give the value for b in terms of a and c from the following question -2(8a+10b)=6c
Answer:
b = (-4/5)a - (3/10)c
--------------
-2(8a + 10b) = 6c
8a + 10b = -3c
10b = -8a - 3c
b = (-8/10)a - (3/10)c
b = (-4/5)a - (3/10)c
