Answer:
d = C - 2/3
Step-by-step explanation:
Subtract 2/3 from both sides of the equation:
C = d + 2/3
-2/3 -2/3
-----------------
C - 2/3 = d
After rearranging the expression and taking the subject d is d = C - 2/3 or d = (3C-2)/3.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
C=d + 2/3
C - 2/3 = d (subtract both side by 2/3)
or
d = C - 2/3 or
d = (3C-2)/3
Thus, after rearranging the expression and taking the subject d is d = C - 2/3 or d = (3C-2)/3.

Point A is located at (3,5) and point B is located at (-2 ,-2).find the distance between point A and B
Answer:
8.74
Step-by-step explanation:
The distance can be calculated by Distance Formula , as :-
⇒ Distance = √[( x₁ - x₂ )² + (y₁ - y₂ )² ]
⇒ D = √ [ ( 3 + 2)² + (5+2)² ]
⇒ D = √ 5² + 7²
⇒ D = √ [ 25 + 49 ]
⇒ D = √ 74
⇒ D = 8.74 units .

Step-by-step explanation:
draw the altitude line to the upper right corner and the lower left corner and you have 2 identical right triangles and a rectangle. If you solve the third side of the right triangles you get 1.685 (sqrt[7.2^2 - 7^2]).
now add up the areas of both triangles and the rectangle in the center whose base is 4.63 (subtract the 3rd side from 8)
you have
1.685(7) + 7(4.63)

Patricia and Whitney began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Patricia took a test in English and earned a 76.5, and Whitney took a test in Math and earned a 64.5. Use the fact that all the students' test grades in the English class had a mean of 73.1 and a standard deviation of 10.5, and all the students' test grades in Math had a mean of 60.9 and a standard deviation of 10.7 to answer the following questions.
a. Calculate the Z-score for Kimberly's test grade.
b. Calculate the z-score for Karina's test grade.
c. Which person did relatively better?
Answer:
a) The Z-score for Patricia's test grade is 0.32.
b) The z-score for Whitney's test grade is of 0.34.
c) Due to the higher z-score, Whitney's did relatively better.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. Calculate the Z-score for Patricia's test grade.
Patricia took a test in English and earned a 76.5. Students' test grades in the English class had a mean of 73.1 and a standard deviation of 10.5.
This means that [tex]X = 76.5, \mu = 73.1, \sigma = 10.5[/tex]
The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{76.5 - 73.1}{10.5}[/tex]
[tex]Z = 0.32[/tex]
The Z-score for Patricia's test grade is 0.32.
b. Calculate the z-score for Whitney's test grade.
Whitney took a test in Math and earned a 64.5. Students' test grades in Math had a mean of 60.9 and a standard deviation of 10.7.
This means that [tex]X = 64.5, \mu = 60.9, \sigma = 10.7[/tex]
The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{64.5 - 60.9}{10.7}[/tex]
[tex]Z = 0.34[/tex]
The z-score for Whitney's test grade is of 0.34.
c. Which person did relatively better?
Due to the higher z-score, Whitney's did relatively better.

I already got part a correct but I need help with part b, I don't understand it cause I'm d u m b pls help
9514 1404 393
Answer:
A) 12 pieces
B) the meaning of the quotient is that Tara got 12 pieces of length 2/5 ft from her 4 4/5 ft rope
Step-by-step explanation:
A) (4 4/5)/(2/5) = (24/5)/(2/5) = 24/2 = 12
Tara can cut 12 pieces from the rope.
__
B) The quotient is the answer to the question. The meaning of it is that Tara can get 12 pieces from the rope, in answer to the question, "how many pieces can Tara cut?"
It doesn't matter whether the numbers are whole numbers, decimals, fractions, or even irrational numbers. The whole is the sum of the parts, so the number of parts is equal to the size of the whole divided by the size of a part.

Comment on the question
This sort of question seems to appear a lot in modern "common core" math materials. They tell you "x means <such and such>", and then they ask you, "What is the meaning of x?" It seems to be a reading comprehension exercise. Of course, the meaning of x is <such and such>, just as the problem statement tells you.
Find y.
1)6.76
2)7.54
3)18.55
4)29.83
9514 1404 393
Answer:
(c) 18.55
Step-by-step explanation:
The law of sines tells you ...
y/sin(106°) = 15/sin(51°)
y = 15×sin(106°)/sin(51°)
y ≈ 18.55
_____
The same kind of proportion can find x:
x = 15×sin(23°)/sin(51°)
x ≈ 7.54
Please note that the question posted here asks for the value of y. The value of x and the complete triangle solution are provided as a courtesy to those who may be asked for other values in this triangle.

use the formula:
[tex]v = u + at[/tex]
v = 30 [final velocity]
u = 10 [initial velocity]
a = 2 [acceleration]
