Answer: 20.15
Step-by-step explanation:
First, make the percentage into an actual number. So divide 65 by 100 (because percent is based off of 100) which gives you 0.65. Then multiply 0.65 by 31 which gives you 20.15. Have a good day ;)

What are linear equations?When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."
There are both one-variable and two-variable linear equations.
Given y = f(x)
and f(x) = -2/3x + 1
to find the value of x when f(x) = -3
substitute the value of f(x)
f(x) = -2/3x + 1
-3 = -2/3x + 1
-2/3x = -3 - 1
2/3x = 4
x = 4*3/2
x = 6
Hence the input is 6.

8. Given two supplementary angles, one angle is forty more than four times a number. The other angle is
twenty less than twelve times a number. Solve for the measure of each angle.
The first angle is 80 and the other angle is 100.
What are supplementary angles?
The pair of angles known as supplementary angles always add up to 180 degrees. These two perspectives are known as each other's supplements.
Let one angle to be 'x', other angle to be 'y' and the number to be 'c'.
So, according to the question:
one angle is forty more than four times a number and the other angle is
twenty less than twelve times a number.
So, x = 4c + 40
and, y = 12c - 20
We know that, the sum of x and y would be 180 because these are supplementary angles.
So, x + y = 180
4c + 40 + 12c - 20 = 180
16c + 20 = 180
16c = 160
c = 10
Hence, x = 4(10) + 40 = 80
and, y = 12(10) - 20 = 100

95 divided by 2?? Please help!
Answer:
47.5
Step-by-step explanation:
95 divided by 2 is equal to 47 with a remainder of 1.
To divide 95 by 2, you need to perform long division.
Here's the step-by-step process:
Write the dividend (95) inside the division bracket, and the divisor (2) outside the bracket.
Place the quotient above the division bracket.
__
2 | 95
Start with the leftmost digit of the dividend (9) and divide it by the divisor (2). Since 9 is smaller than 2, we move to the next digit.
__
2 | 95
4
Bring down the next digit of the dividend (5) to the right of the remainder
(1) obtained from the previous step.
__
2 | 95
4 1
Divide 15 by 2. The quotient is 7, and the remainder is 1.
__
2 | 95
47 1
Since there are no more digits in the dividend, we have completed the division.
The quotient is 47, and the remainder is 1.
Therefore, 95 divided by 2 is equal to 47 with a remainder of 1.

2% in. Find the height of the popcorn box in inches. Round your answer to the
nearest tenth if necessary.
The height of the popcorn box is 8.75 inches.
What is the rectangular prism?
A rectangular prism is a three-dimensional geometric shape with six rectangular faces. It is also known as a rectangular cuboid, or simply a cuboid. It has three dimensions: length, width, and height. It can be represented by the formula: V = lwh where l is the length, w is the width, and h is the height.
We can use the formula for the volume of a rectangular prism to solve this problem. The formula is:
V = l * w * h
where V is the volume, l is the length, w is the width, and h is the height. We know that the volume of the box is 35 cubic inches and that the length and width are 2 inches each. So we can substitute those values into the formula and solve for h:
35 = 2 * 2 * h
To find h, we'll divide both sides of the equation by 4.
h = 35/4 = 8.75
Hence, the height of the popcorn box is 8.75 inches.

Given, A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand contains 13% vinegar. The chef wants to make 360 milliliters of a dressing that is 9% vinegar.
to set up an equation that will match the word problem. Let's call the amount of the first brand, F, and the amount of the second brand, S.
We want the total mixture to be 360mL so: F + S = 360
Also, you want the total mixture to contain 8% vinegar so:
.08F + .13S = .09(360)
Now, we can solve the system of equations using substitution.
F + S = 360
.08F + .13S = .09(360)
F = 360 - S [solve 1st equation for F]
.08(360 - S) + .13S = .09(360) [substitute into 2nd equation]
28.8 -0.08s+0.13s = 32.4

Is H2 one mole or two?.
H₂ is two moles.
The molecular mass of an element is described as the sum of the masses of all the atoms present in the molecule.
Molecular mass is acquired by adding the atomic masses of all atoms with the number of atoms in the molecule.
H₂ has two atoms, so a mole of H₂ would have 1 mole of H₂ molecules, and when broken down into atoms, 2 moles of atoms.
Think about it like pairs of shoes. If you have 6 pairs of shoes, you have 12 pairs of shoes.
CO₂ has 3 atoms, 2N₂0 has 3 atoms, and there are already 2 moles, so that would be 6 moles of atoms; 2NaCl has 2 atoms but again, that 2 indicates that you'd have 4 moles of atoms, and H₂SO₄ has 7 atoms.

Answer: B=294
Step-by-step explanation:
Uing the lope-intercept form, give the equation of the line if the y-intercept i (0,6) and the lope i 15. A x = 6y -15
B y = 15x 6
C x = 15y 6
D y = 6x - 15
The equation of the line if the y-intercept i (0,6) and the lope i 15 is:
B. y = 15x 6
Linear Equation SolutionThe equation of the line is given in slope-intercept form (y = mx + b) where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis and is given as (0,6). Therefore, the value of b is 6. The slope is given as 15. Therefore, the equation of the line is y = 15x + 6. This equation means that for every unit increase in x, y increases by 15 units and the line passes through the point (0,6)
This method is applicable for other equations as well, as long as they are in slope-intercept form (y = mx + b). The slope-intercept form is a way to represent a linear equation where the slope and the y-intercept are known. If the equation is not in that form, it can be rearranged to make it so. Once the equation is in slope-intercept form, you can identify the slope and the y-intercept which can be useful in understanding the characteristics of the line such as its direction and position in the coordinate plane.
