13% of $67.99 please help me please
Answer:
8.8387 (round to 8.84)
Step-by-step explanation:
To find the percentage of something, convert the percent into decimal form by moving the decimal two places to the left. In this case, the decimal form of 13% is 0.13
Then, multiply this decimal by the number you need to find the percentage of. In this case, that number is 67.99
The result of .13x67.99 is 8.8387.
Answer:
$8.84
Step-by-step explanation:
1.) Start with the 13%
2.) You have 13.
3.) Move the decimal point 2 places to the left.
4.) Now you have 0.13
5.) Multiply 0.13 and 67.99
6.) This equals $8.84

Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
So we have the equation:
[tex]5+(x-2)=-8[/tex]
Let's subtract 5 from both sides:
[tex](5+(x-2))-5=(-8)-5[/tex]
The left side will cancel. Subtract on the right:
[tex]x-2=-13[/tex]
Now, add 2 to both sides:
[tex](x-2)+2=(-13)+2[/tex]
Again, the left side will cancel. Add the right:
[tex]x=-11[/tex]
And we're done!
Answer:
it should be x=5
Step-by-step explanation:
5+(x-2)= -8
3+x=8
-3 -3
answer is x=5
Raul and his friends, each of whom weighs 1/20 of a ton, are standing on a truck scale. The total weight shown by the scale is 3/4. How can you find the total number of people on the scale when raul and his friends are weighed?
Answer:
There are 15 friends
Step-by-step explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) in the same proportion, the rule of three applies as follows:
a ⇒ b
c ⇒ x
Then: [tex]x=\frac{c*b}{a}[/tex]
where a, b and c are known values and x is the value to be calculated.
In this case, the rule of three applies as follows: if 1/20 of a ton is the weight of 1 person, 3/4 of a ton is the weight of how many people?
[tex]number of people =\frac{\frac{3}{4} of a ton*1 person }{\frac{1}{20} of a ton}[/tex]
or, what is the same,
number of people* [tex]\frac{1}{20}[/tex] = [tex]\frac{3}{4}[/tex]
Solving:
number of people= 15
There are 15 friends
The graph shows the motion of a train on a railroad. Which statement describing the motion of the train is best supported by the graph? Math item stem image CLEAR CHECK The train is traveling on a level surface. The train is moving at a constant positive speed. The train is not moving. The train track is straight.
Answer:
The train is not moving
Step-by-step explanation:
The graph does not show the train's motion. It shows the train's position, which is constant. ("Distance" is not a measure of motion. It is a measure of position.)
If the train's position is constant, it is not moving.

[tex] \longmapsto{ \sf{50x = 10 + 15}}[/tex]
Add the numbers: 10 and 15
[tex] \longmapsto{ \sf{50x = 25}}[/tex]
Divide both sides by 50
[tex] \longmapsto{ \sf{ \frac{50x}{50} = \frac{25}{50}}} [/tex]

What is the y-intercept of the line that is
perpendicular to y = -3x - 5 and passes
through the point (-3,7)?
A-3
B 1/3
C 8
D 10
Answer:
The y-intercept of the line would be (C) 8
Step-by-step explanation:
The slope of the line with the equation y = -3x - 5 is -3. When figuring out a slope perpendicular to another line you would use the negative reciprocal of the slope which would lead to the slope of the line to be 1/3.
We know it passes through the point (-3,7), substituting x and y, we would then get our new equation, [tex](7) = \frac{1}{3}( -3) + b[/tex].
Solve the equation by multiplying -3 with 1/3 and the product would be -1. Add negative one on both sides and you would get 8 = b.

Which function is the inverse of f(x) = 2x+3?
Answer:
f^-1(x)=x-3/2
Step-by-step explanation:
we have f(x)=2x+3
let

y=2x+3
Exchanges the variables x for y and y for x
x=2y+3
isolate the variable y
2y=x-3
y=x-3/2
let
f^-1(x)=y
f^-1(x)=x-3/2
Answer:
Step-by-step explanation:
The answer is B on Edgenuity
f^-1 (x) = 1/2x - 3/2
Solve for w: -4u-w = u+6w
Answer:
A
Step-by-step explanation:
-4u - w = u + 6w
-4u = u + 7w (Add w to both sides)
-5u = 7w (Subtract u from both sides)
w = [tex]-\frac{5u}{7}[/tex] (Divide both sides by 7)
Answer:
w=(-5u)/7
Step-by-step explanation:
-4u-w=u+6w
Combine like terms
-4u-u=6w+w
-5u=7w
Divide both sides by 7 to cancel it out on the right side and isolate w
(-5u)/7=(7w)/7
(-5u)/7=w
w=(-5u)/7

what is (10y+6) (8y-6) ?
Answer:
y = 3/4 or y = -3/5
Step-by-step explanation:
Solve for y:
(8 y - 6) (10 y + 6) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
8 y - 6 = 0 or 10 y + 6 = 0
Hint: | Look at the first equation: Factor the left hand side.
Factor constant terms from the left hand side:
2 (4 y - 3) = 0 or 10 y + 6 = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 2:
4 y - 3 = 0 or 10 y + 6 = 0
Hint: | Isolate terms with y to the left hand side.
Add 3 to both sides:
4 y = 3 or 10 y + 6 = 0
Hint: | Solve for y.
Divide both sides by 4:
y = 3/4 or 10 y + 6 = 0
Hint: | Look at the second equation: Factor the left hand side.
Factor constant terms from the left hand side:
y = 3/4 or 2 (5 y + 3) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 2:
y = 3/4 or 5 y + 3 = 0
Hint: | Isolate terms with y to the left hand side.
Subtract 3 from both sides:
y = 3/4 or 5 y = -3
Hint: | Solve for y.
Divide both sides by 5:
Answer: y = 3/4 or y = -3/5
Use the graph shown to answer the question. What is the solution set for the inequality if log2(2x – 1) > 2?
Answer: B
(2.5, ∞)
Step-by-step explanation:
The solution set of the given logarithm inequality will be (2.5,∞).
What is a logarithm?The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.
In another word, a logarithm is a different way to denote any number.
As per the given logarithm function,
log₂(2x - 1) > 2
By log property
2x - 1 > 2 x 2
2x > 4 + 1
x > 5/2
x > 2.5 so the solution set will be 2.5 < x < ∞ or (2.5,∞).
Hence "The solution set of the given logarithm inequality will be (2.5,∞)".

What is the equation of the line that passes through the point (2, -1) and has a slope of 3/2?
Answer:x=-2
Step-by-step explanation: -1=3/2x+2
Given :-
A line having a slope of 3/2 passes through (2,-1) .
To Find :-
The equation of the line .
Answer :-
According to the question ,
m = 3/2
Point = (2,-1)
We know Point slope form of the line as ,
y - y¡ = m ( x - x ¡ )
Substitute ,
y - (-1) = 3/2 ( x - 2 )
y + 1 = 3/2x - 3/2*2
y +1 = 3/2x - 3
2( y +1) = 3/2x *2 - 3*2
2y + 2 = 3x - 6
3x -2y -8 = 0

The larger of two complementary angles is 6 degrees less than 7 times the smaller. Find the measure of the smaller angle.
Answer:
Step-by-step explanation:
The sum of two complementary angles is 90.
Let the two angles be x and y.
If x and y are complementary, then x+y = 90
If the larger of two complementary angles is 6 degrees less than 7 times the smaller then y = 7x-6 (y is the larger and x is the smaller)
Substituting y = 7x-6 into the formula above;
x+7x-6 = 90
8x - 6 = 90
8x = 90+6
8x = 96
x = 96/8
x = 12°
Hence the measure of the smaller angle is 12°
