35
Step-by-step explanation:
To find the original number multiply by the reciprocal of [tex]\frac{3}{5}[/tex] , that is
number = [tex]\frac{5}{3}[/tex] × 21 = [tex]\frac{105}{3}[/tex] = 35
What is the number for x?

Answer:
C) 375
Step-by-step explanation:
Multiple 75 on both sides, which eliminates the denominator 75.
[tex]\frac{x}{75} = 5\\x = 5(75)=375[/tex]

Answer:
The number of days in y hours is y/24
Step-by-step explanation:
Here, we want to write an expression
Mathematically;
1 day = 24 hours
? days = y hours
? days = (y * 1)/24
? days = y/24
Name each pair of angles as corresponding, alternate interior, alternate exterior, or consecutive. Then solve for x.
Answer:
x = -2
Step-by-step explanation:
These 2 angles are alternate exterior so they're equal to each other.
x + 127 = 125
x = 125 - 127
x = -2

A rocket is launched into the air. The height h(t), in yards, of the rocket is a function of time, t, in seconds, as shown in the following table.
What is the rocket's average rate of change from 3≤t≤6 in yards/second?
Enter your answer as a number, like this: 42
Answer:
From 3 to 6 seconds, the rocket is falling 11 yards per second.
Step-by-step explanation:
Normal pace of progress is exactly the same thing as the slant. Since this is explanatory, we can't track down the specific pace of progress as we could if this were a straight capacity. Be that as it may, we can utilize a similar thought. At the point when t = 3, h(t) = 33, so the organize point is (3, 33). At the point when t = 6, h(t) = 0, so the facilitate is (6, 0). Attachment those qualities into the incline recipe:
m= 0-33/6-3 and m=-33/3 which is 11
From 3 to 6 seconds, the rocket is falling 11 yards each second.

if p is inversely proportional to the square of q, and p is 9 when q is 5, determine p when q is equal to 3
Answer: tell me if i am wrong
p = 304
Step-by-step explanation:
Given p is inversely proportional to q² then the equation relating them is
p = [tex]\frac{k}{q^{2} }[/tex] ← k is the constant of proportion
To find k use the condition p = 19 when q is 8, then
19 = [tex]\frac{k}{8^{2} }[/tex] =[tex]\frac{k}{64}[/tex] ( multiply both sides by 64 )
k = 1216
p = [tex]\frac{1216}{q^{2} }[/tex] ← equation of proportion
When q = 2, then
p = [tex]\frac{1216}{2^{2} }[/tex]=[tex]\frac{1216}{4}[/tex]=304
The measure of the vertex angle of an isosceles
triangle is 76 . Find the measure of a base angle.
Answer:
52
Step-by-step explanation:
Let each of the base angles = x
x + x + 76 = 180 Subtract 76 from both sides
x + x = 104 Combine the 2 xs
2x = 104
x = 52
Each base angle has a measure of 52

Answer:
B
Step-by-step explanation:
A linear function is described by a x term to the power of 1 or even 0. A function when x is to the second power is most usually not a linear function.
In answer A, you have x multiplied against -3x. This will cause an x squared term, so this is not a linear function.
In answer B, you have 1/2 multiplied against x, which is a regular x term subtracted by 2x, causing a regular x term, meaning this function is linear. However, in the small possibility it is not, we will keep going.
In answer C, there is an x squared term so this is not linear.
In answer D, the expression has 1/2x times 2x, which will cause an x squared term.
Thus, the answer is B, which is the only equation without an x squared term.
Easton needed to get his computer fixed. He took it to the repair store. The technician
at the store worked on the computer for 3.25 hours and charged him $196 for parts.
The total was $342.25. What was the cost of labor, per hour?
Answer:
if i did all the math right it is $45 and hour
Step-by-step explanation:
$342.25 - $196 = $146.25
$146.26 ÷ 3.25 = $45. so $45 an hour
Hailey is designing a new board game, and is trying to figure out all the possible
outcomes. How many different possible outcomes are there if she rolls a fair die in
the shape of a pyramid that has four sides labeled 1 to 4 and spins a spinner with four
equal-sized sections labeled Red, Green, Blue, Orange?
Given:
Numbers on die = 1, 2, 3, 4
Colors on board = Red, Green, Blue, Orange (equal sized sections)
To find:
The number of different possible outcomes are there if she rolls a fair die in the board.
Solution:
According to the given information,
The total possibilities for numbers = 4
Total possibilities for colors = 4
Total possibilities = Possibilities for number × Possibilities for colors
= [tex]4\times 4[/tex]
= [tex]16[/tex]
So, total 16 possible outcomes are there if she rolls a fair die in the board.
Let Red=R, Green=G, Blue=B, Orange=O, then list of total possible outcomes is:
{1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}
Therefore, the total possible outcomes are 16 and the lies of outcomes is {1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}.

An airplane takes off at an angle of 15 degrees with the ground. To the nearest 10 feet, how far has the airplane flown when it has covered a horizontal distance of 1800 feet?
Answer:
1738.67 feet
Step-by-step explanation:
Imagine a right angles triangle, with the base length of 1800ft and the angle between the base and the hypotenuse to be 15 degrees.
Now, we have to calculate the hypotenuse length, using trigonometric ratios
The ratio that links adjacent side and hypotenuse is cos
So, write an equation:
cos(15) = Adjacent/Hypotenuse = 1800/H
Rearrange to solve.
H = cos(15) x 1800 = 1738.67
This is the distance flown by the aeroplane .
Hope this helps
∠C and \angle{D}∠D are vertical angles. If the m\angle{C} m∠C=66o, then what is the m\angle{D} m∠D ?
Answer:
The measure of angle D is of 66º.
Step-by-step explanation:
Vertical Angles:
If two angles are vertical, they have the same measure.
In this question:
Angles C and D are vertical.
Angle C measures 66º.
So the measure of angle D is of 66º.

A 1200 kg car and a 2400 kg car are lifted to the same height at a constant speed in a auto service station. Lifting the more massive car requires ____ work.
to be honest with you, I dont know
The work required to lift the massive car of 2400 kg is more than lifting the car with 120 kg
What is Work?Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. For a constant force acting in the same direction as the motion, the work is defined as the product of the force's magnitude and the distance traveled. The dimensions of work is
ML²T⁻² and the SI unit of work is Joule
Work = Force x Distance
The SI unit for work is the joule (J), or newton meter ( Nm ). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Given data ,
Let the work required to move the 2400kg car be W₁
Let the work required to move the 1200kg car be W₂
Now , the force in moving the 2400 kg car = F₁
The value of F₁ = 2400 ( a )
And , the force in moving the 1200 kg car = F₂
The value of F₂ = 1200 ( a )
where a is the acceleration
Let the distance moved be height H
Now , the work W₁ = Force x Distance
Substituting the values in the equation , we get
W₁ = 2400 ( a ) H
And , W₂ = 1200 ( a ) H
Now , W₁ > W₂
Hence , the work required to move 2400 kg car is greater

Michael is considering four different job offers. He estimates that 12% of his income will go to his taxes. He created a table in order to determine how much his take home pay will be from each job.
Answer:
Michael's take home pay from each job are;
[tex]\begin{array}{cccc}Gross \ Income& Take \ home \ Pay\\\$1,250& \$1,100\\\$1,525 &\$1,342\\\$1,850&\$1,628\\\$2,200&\$1,936\\\\Sum&\$6,006\end{array}\\[/tex]
Step-by-step explanation:
The given parameters are;
The percentage of Michael's income that he estimates will go to his taxes = 12%
The number of jobs Michael has = Four jobs
The table Michael created can be presented and the estimated taxes and the take home pay entered as follows;
Tax owed = Gross income × Tax percent

Tan 0 and Cot O
Answer:
Step-by-step explanation:
we can say the angle is also +45° going in the clock wise direction. so take Tan(45)= 1
Cot(45) = 1
b/c Tan(45) = Sin(45) /Cos(45) = ([tex]\sqrt{2}[/tex]/2) / ([tex]\sqrt{2}[/tex]/2) ofc that's just 1
b/c Cot(45) = Cos(45) / Sin(45) , which is the same as above 1
