Answer:
The number of students decreased by 30%.
Step-by-step explanation:
Subtract 1430 from 1001, then find the absolute value.
[tex]\frac{|1001-1430|}{1430}\\\frac{|-429|}{1430}\\\frac{429}{1430}[/tex]
Simplify 429/1430 by cancelling out 143.
[tex]\frac{429/143}{1430/143}\\\frac{3}{10}[/tex]
Convert 3/10 into a percentage by multiplying it by 100.
[tex]\frac{3*100}{10}\\\frac{300}{10}\\30[/tex]
The decrease of students was 30%.

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.

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.

SOLVE FOR x IN THE DIAGRAM BELOW
Answer:
x = 12°
Step-by-step explanation:
(x + 42) + 3x = 90°
(The interior angle equals 90°)
Simplify.
4x + 42 = 90
Subtract.
4x = 48
Divide.
x = 12°
good luck, i hope this helps :)
Answer:
x= 12°
Step-by-step explanation:
Information needed:
The two angles add up to 90°
Equation: (x+42)+3x= 90°
Solve:
(x+42)+3x= 90°
x+42+3x= 90°
x+3x+42= 90°
4x+42= 90°
-42 -42
4x= 48°
/4 /4
x= 12°
Peyton listed five rational numbers. Then he drew a number line to display and compare them
Answer:
OK so, starting from left to right it should be -1.75, -3/4, 1/4, 0.75, 1 1/2
Step-by-step explanation:
Simply go from the smallest to the largest number.
If it's a negative the bigger the number is actually going to be less.
How would you write this inequality in words? 42-J<12
forty two minus J is less than 12
or...
forty two minus J is less than or equal to 12
or...
forty two minus J is greater than 12
Answer:
forty two minus J is less then twelve
Step-by-step explanation:
the less than symbol is small on the left and big on the right
the greater than symbol is big on the left and small on the right
the equal to symbol has a line under the symbol
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.
