Answer: 0.78 and 39/50
Explanation:What we know:
We need to find 78% as a fraction and decimalHow to solve:
The decimal is easy enough, and then the fraction can be found from there. D will represent decimal, p will represent percentage, and F will represent fraction.
Process:Decimal
Set up equation D = p / 100
Substitute D = 78% / 100
Simplify D = 0.78%
Remove % sign D = 0.78
Fraction
Set up equation F = p / 100
Substitute F = 78% / 100
Remove % sign F = 78 / 100
Simplify if needed F = /2 /2
F = 39 / 50
Solution: 0.78 and 39/50
Check:
Multiply the decimal by 100 to check the decimal
0.78 x 100 = 78; 78%
Divide the fraction to check the fraction
39/50 = 0.78; see above

The square root of 72?
Answer:
6√2
Step-by-step explanation:
The square root of 72 is an irrational number, so we can't make the square root of 72 into an accurate decimal form. However, we can simplify it!
The factors that have the greatest square are 2 and 36.[tex]\sqrt{72} = \sqrt{36} * \sqrt{2}[/tex] [tex]\sqrt{36} *\sqrt{2} = 6\sqrt{2}[/tex]Therefore, the answer is 6√2.
Answer:
8.48 or [tex]\sqrt[6]{2}[/tex] (simplified)
Step-by-step explanation:
When we first try solving the square root of 72, we get [tex]\sqrt[6]{2}[/tex].
Next we simplify that square root, and get 8.48528 or just 8.48.

helpppp !!!!!!! pls and ty alot
===================================================
Explanation:
The given equation is in the form y = mx+b
m = -3/2 is the slope
b = 2 is the y intercept
The y intercept tells us where the graph crosses the vertical y axis. In this case, it's at 2 on the y axis. Think of the y axis as a number line that is simply vertical.
So we'll have (0,2) as one point on the line.
From this point, move down 3 units and to the right 2 units to arrive at (2,-1) as our next point. We only need two points to graph a straight line. You can repeat the process "down 3, over to the right 2" to generate as many points as you want.
The "down 3, over to the right 2" is from the slope -3/2
slope = rise/run = -3/2
rise = -3 means we move down 3
run = 2 means we move to the right 2
---------------------
Another approach is to plug in numbers for x to get corresponding values for y.
If we pick on x = 0, then,
y = (-3/2)*x + 2
y = (-3/2)*0 + 2
y = -1.5*0 + 2
y = 0 + 2
y = 2
So this shows (0,2) is one point on the line.
If we plug in x = 2, then,
y = (-3/2)*x + 2
y = (-3/2)*2 + 2
y = -1.5*2 + 2
y = -3+2
y = -1
Meaning (2,-1) is another point on the line.

4 \$70.8099 \$159.30
28 \$495.60
How long does it take him to make \$132.75
Answer:
7.5 hrs.
Step-by-step explanation:
First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]
y = mx + b
y = 17.7x + b
I will be using (4, 70.80) to find the value of b
(4, 70.80)
y = 17.7x + b
70.80 = 17.7(4) + b
70.80 = 70.80 + b
-70.80 -70.80
0 = b
y = 17.7x + b ==> y = 17.7x + 0 = OR y = 17.7x (since the value of b is 0)
The question wants us to find out how long it took Magan to make $132.75
y = 17.7x
132.75 = 17.7x
/17.7 /17.7
7.5 = x
This means that it took him 7.5 (seven and a half) hours to make $132.72

Consider the pairs of ratios given in the first column and determine whether or not the ratios form a proportion.
Answer:
Options 1 and 2 are proportional, the last one isn't.
Step-by-step explanation:
I found option 1 by dividing 8 / 1, then multiplying it by 2 to see if I get 16. I got 16 so it's proportional.
I found the 2nd option by dividing 9 / 4, and then multiplying it by 8 to see if I get 18. I got 18 so it's proportional.
I found option 3 by dividing 16 / 6, and then multiplying it by 4 to see if I get 10. I didn't 10, so it isn't proportional.

how does knowing the difference between the gain and the loss tell you the overall result?
Knowing the difference between the gain and the loss is essential to determine if a result is positive or negative, especially in commercial or economic operations.
Thus, the existence of a greater amount of negative elements than positive ones will imply a loss, with which it will not be recommended to carry out the activity given the high risk of loss.
In this way, a previous study of the conditions and probabilities of the operation can prevent losses and favor positive results.

Could you find the Area?
Answer: 35!
Step-by-step explanation
The length is 7 and the width is 10 so length x width = area which is 7x10=70. The area of the small rectangle is 5x7 which is 35. So altogether 70+35=105. and you would have to subtract it because you only want to know the length of the frame. So 70-35=35!

Step-by-step explanation:
The sum of the angles of the triangle is 180
x+10 + x + 3x-5 = 180
Combine like terms
5x +5 = 180
Subtract 5 from each side
5x+5-5= 180-5
5x = 175
Divide each side by 5
5x/5 =175/5
x=35
