Of the 120 math tests, 47 were Bs. What percent of the math tests were Bs? Round to the nearest whole percent.
Answer:
39.17%
Step-by-step explanation:
Answer:
39%
Step-by-step explanation:
Percent is ALWAYS out of 100, and the unknown is percent so our first part of the equation will be %/100. Now our second part of equation: is/of
Of represets whole the total, and we have our key word “Of the 120 math tests”. We have our total: 120; 47 is our part so second part of equation: 47/120.
Our equation so far: %/100 = 47/120 now we need to multiply the numbers that we have diagonally: 100% x 47; 47/100 we’re multiplying so we’ll move two 0s to the right. Answer: 4700
Now, we’ll divide 4700 by 120. 4700/120. Answer: 39.1666666667. Round to nearest whole means round to nearest ones.
Thus, the answer is 39.
Hope this is helpful!
Jeff worked 4 2/3 hours in the morning and 3 3/4 hours in the afternoon. How many total hours did he work today?
7 5/7 hours
7 5/12 hours
8 5/12 hours
8 1/2 hours
Answer:If you would like to know how many total hours did Jeff work today, you can calculate this using the following steps:
4 2/3 hours in the morning + 3 3/4 hours in the afternoon = 4 2/3 + 3 3/4 = 14/3 + 15/4 = 56/12 + 45/12 = (56 + 45) / 12 = 101/12 = 8 5/12 hours
Jeff worked 8 5/12 hours in total.

Explain relationship between the factors of a quadratic expression, the roots of the related quadratic equation, and the x-intercepts if the graph of the related function
Step-by-step explanation:
So, let's use x2 - 3x - 28 as an example.
It's factors are (x - 7)(x + 4).
The roots are the x-values that make our expression equal 0. In order for x2 - 3x - 28 to equal 0, either of our factors need to equal 0, since 0 times anything is 0.
x2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0
x = 7
(7 - 7)(7 + 4) = 0(11) = 0
x + 4 = 0
x = -4
(-4 - 7)(-4 + 4) = -11(0) = 0
That gives us two points on our graph, (7,0) and (-4,0). Where are those? On the x-axis! Thus, there are our x-intercepts.
By the way, for the future, along the x-axis, y = 0, so if you are asked for the x-intercepts (or roots), set y = 0 and solve for x.
Along the y-axis, x = 0, so if you are asked for the y-intercepts, set x = 0 and solve for y.
y = 02 - 3(0) - 28
y = -28
So, the y-intercept(s) of our same equation is y = -28, or (0,-28).
Boom.
Answer:
The x-intercepts are happen are when y = 0. If you tried to substitute y = 0 into a quadratic in the standard form you can not use traditional methods for solving for x.
Y=0 when looking for an x-intercept. Doing the factored form you are finding the x-intercepts. You always want the equation to equal 0 then factor out the equation till you get the numbers for the x-intercept.

ONE STEP EQUATION :
1. When solving the equation -2x = 14; how would you solve for x? What would x equal?
2. When solving the equation 7 + x = -3; how would you solve for x? What would x equal?
3. When solving the equation x/5 = -4; how would you solve for x? What would x equal?
Answer:
Question one X=-7 because -2 x -7 = 14
Question two X= -10 because -3 - -10=7
Question three X =-20 because -4 divided by-20

Rebecca is buying a new video game system that costs $190. The state sales tax rate is 4%. How much tax will Rebecca pay on the video game system?
Answer:
If the sales tax rate is 4%, the total amount of money that Rebecca will pay is equal to 190(1.04), or 197.60 dollars. This means, that the tax that Rebecca needs to pay is just 7.60 dollars.

i need help with this question please
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

DeAngelo rode his bike at a rate of 12 miles per hour. At that rate, how far could he ride in three hours?
At the given rate, he could ride 36 miles in three hours
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
DeAngelo rode his bike at a rate of 12 miles per hour.
At that rate,
He rode in three hours,
= 3 x given rate
= 3 x 12
= 36
= 36 miles.
Therefore, he rode 36 miles in three hours.
