Step-by-step explanation:
Kevin's weekly salary is 865. He receives a 25% raise. How can Kevin find his new weekly salary? Select all that apply.
a. divide 865 by 0.25
b. divide 865 by 1.25
c. multiply 865 by 0.25
d. multiply 865 by 1.25
e. add 865 and 1/4 of 865
f. add 865 and 1 1/4 of 865
Answers
Answer:
Option d. (also option e depending on which way you want to calculate it)
Step-by-step explanation:
First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.
______________________________________
More Simple Explanation:
Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!
______________________________________
More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:
1) Calculate the new value of the number increased by percentage of its initial value
The new value =
865 + The value of the percentage increase =
865 + (25% × 865) =
865 + 25% × 865 =
(1 + 25%) × 865 =
(100% + 25%) × 865 =
125% × 865 =
125 ÷ 100 × 865 =
125 × 865 ÷ 100 =
108,125 ÷ 100 =
1,081.25
2) Calculate the actual change (the difference) between the new value and the initial one
The actual change =
The new value - 865 =
1,081.25 - 865 =
216.25
(For positive numbers, the actual change = The value of the percentage increase)

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get

x = 7.5, y = 8.5-----------------------------------
The two angles with the variable x form a linear pair and therefore:
16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5Angles 16x - 18 and 12y are congruent as vertical angles:
16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5Answer:
x = 7.5
y = 8.5
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
To find x, equate the sum of the two angles with the variable x to 180° and solve:
⇒ (16x - 18)° + (10x + 3)° = 180°
⇒ 16x - 18 + 10x + 3 = 180
⇒ 26x - 15 = 180
⇒ 26x = 195
⇒ x = 7.5
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ (16x - 18)° = 12y°
Substitute the found value of x into the equation and solve for y:
⇒ 16x - 18 = 12y
⇒ 16(7.5) - 18 = 12y
⇒ 120 - 18 = 12y
⇒ 102 = 12y
⇒ y = 8.5
There are nine water bottles in Devin's refrigerator. He adds three full boxes of water bottles to the refrigerator. Then he adds two more boxes that each has 1 fewer bottle than a full box. When he is done, there are 67 bottles in the refrigerator. Write and solve an equation to find the number of bottles in a full box.
Answers
Answer:
12
Step-by-step explanation:
let x be 1 full box
9 + 3x + 2(x -1) = 67
67 - 9 = 58
3x + 2(x -1) = 58
expand 2 into the bracket
3x + 2x - 2 = 58
5x = 60
x = 12
Answer:
9+3x+2(x-1)=67
x=12
Step-by-step explanation:
So we have 9 water bottles, so we put that as 9 in our equation. Then he adds 3 full boxes of water bottles, but we don't know how many water bottles are in each box, so we would label that as x, so it would be 3x. Then he adds two more boxes that each has 1 fewer bottles than a full box, so that would be 2(x-1) because we know that each box has x amount of water bottles, and you just subtract one, and we also know that we have 2 of those boxes. Then, when he is done, that means the whole equation equals, 67. Our equation would be 9+3x+2(x-1)=67. Now we solve for x.
9+3x+2x-2=67
9+5x-2=67
9-2+5x=67
7+5x=67
5x=60
x=60/5
x=12

-6x - 1.5 =< 4.5 -2.5x -2.5
Combine like terms on right
4.5-2.5=2 Add 2.5x to both sides and add 1.5 to both sides. You get

Which statement is true? A.Parallel lines intersect to form four right angles. B. Parallel lines intersect at no more than one point. C. Parallel lines always be the same distance apart.
Answers
Answer:
C
Step-by-step explanation:
Parallel lines never touch so they cant be intersecting so C is the only possible answer
The statement "parallel lines always be the same distance apart" is true.
What are parallel lines?Parallel lines are two or more lines in a plane that are equidistant from each other at all points.
Parallel lines are lines that are always the same distance apart and never intersect. They are denoted with arrowheads pointing in the same direction. This means that no matter how far they are extended in either direction, they will never meet.
Option A is false. Parallel lines never intersect, so they cannot form any angles, let alone four right angles.
Option B is also false. Parallel lines can intersect in a special case known as hyperbolic geometry, but in Euclidean geometry (the geometry that we use in our everyday lives), parallel lines do not intersect at all.
Therefore, option C is the correct statement.
