To make a specific hair dye, a hair stylist uses a ratio of 118 oz of red tone, 34 oz of gray tone, and 58 oz of brown tone. If the stylist needs to make 20 oz of dye, how much of each dye color is needed?
Answer:
The answer is, the hair stylist needs 5.9 oz of the red tone, 1.7 oz of gray tone, and 2.9 oz of brown tone
Step-by-step explanation:
It says if the stylist needs to make 20 oz of dye,how much of each dye is needed? So you need to divide 20 by 118,34,and 58.
Step 1:Highlight important words that can help answer the question
Highlight:How much,each,ratio,is needed
Step 2:Collect data(numbers) from the algebraic equation
Example:118 oz, 34 oz, 58 oz, 20 oz
Step 3:Divide 20 by each ratio of dye
118/20
34/20
58/20
Step 4:Get the quotient of each dividend
118/20=5.9
34/20=1.7
58/20=2.9
Step 5:Check your work to make sure it's correct. Note:If you check your work but it's not right try again.
20 x 5.9=118
20 x 1.7=34

Answer:
SU = 2PX = 6 2/3Step-by-step explanation:
The product of distances to the circle along a secant is the same for all secants intersecting a given point.
a. Secants SW and QT intersect at U. Thus ...
(UT)(UQ) = (US)(UW)
(1.5)(4) = (SU)(3)
SU = (4)(1.5)/3
SU = 2
__
b. Secants PT and PX intersect at P. Thus ...
(PQ)(PT) = (PR)(PX)
PX = (PQ)(PT)/PR) = (2.5)(2.5 +4 +1.5)/3 = 20/3
PX = 6 2/3

The position of an object at time t is given by s(t) = -9 - 3t. Find the instantaneous velocity at t = 8 by finding the derivative. 20 POINTS
Work Shown:
s(t) = -9 - 3t
s ' (t) = -3 ... apply the derivative
The position function is linear, so the derivative is constant. The slope of any straight line is the same regardless of where you are on it, so that's why the velocity is a single fixed number. Put another way, the slope of the line is exactly the velocity (since slope = rise/run = change in distance over change in time). It doesn't matter what the value of t is, the velocity will be -3

A lot consisting of 50 bulbs is inspected by taking at random 10 bulbs and testing them. If the number of defective bulbs is at most 1, the lot is accepted; otherwise it is rejected. If there are 10 defective bulbs in the lot, what is the probability of accepting the lot?
Answer:
0.3487
Step-by-step explanation:
The probability of accepting the lot If there are 10 defective bulbs in the lot is; 0.3487
This involves binomial probability distribution which is given by the formula;P(X = r) = ⁿ[tex]C_{r}[/tex] × [tex]p^{r}[/tex] × [tex]q^{1 - r}[/tex]
We are given;Number of bulbs taken at random = 10
We are told that if the number of defective bulbs is at most 1, then the lot is accepted.
This means that probability of success is; p = 1/10 = 0.1
q = 1 - p
q = 1 - 0.1
q = 0.9
If there are 10 defective bulbs, then the probability of accepting the lot is;P(X = 0) = ¹⁰[tex]C_{0}[/tex] × [tex]0.1^{0}[/tex] × [tex]0.9^{10 - 0}[/tex]
P(X = 0) = 0.3487

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality. 34 and 12
Answer:
[tex]22 < X < 46[/tex]
Step-by-step explanation:
Given
Two sides of a triangle; 34 and 12
Required
Determine the range of the third side
Represent the third side with X
To determine the range of the third side; two of the following conditions must be satisfied'
[tex]34 + X > 12[/tex]
[tex]34 + 12 > X[/tex]
[tex]12 + X > 34[/tex]
Solving 34 + X > 12
Subtract 34 from both sides
[tex]34 - 34 + X> 12 - 34[/tex]
[tex]X > -22[/tex]
Solving 34 + 12 > X
[tex]34 + 12 > X[/tex]
[tex]46 > X[/tex]
Solving 12+ X > 34
Subtract 12 from both sides
[tex]12 - 12 + X > 34 -12[/tex]
[tex]X > 22[/tex]
Write out the results
[tex]X > -22[/tex]
[tex]46 > X[/tex]
[tex]X > 22[/tex]
The first inequality will be discarded because it accommodates negative digits;
So, we're left with
[tex]46 > X[/tex] and [tex]X > 22[/tex]
This can be rewritten as
[tex]X < 46[/tex] and [tex]22 < X[/tex]
Combine both inequalities;
[tex]22 < X < 46[/tex]
Hence, the range of the third length is [tex]22 < X < 46[/tex]

Given: f(x) = x2, g(x) = x + 6, h(x) = 7
Find f(g[h(x)]).
55
169
26
Answer:
169
Step-by-step explanation:
f(x) = x^2, g(x) = x + 6, h(x) = 7
f(g[h(x)])
Replace h(x) with 7
f(g(7))
g(7) = 7+6 = 13
Replace g(7) with 13
f(13) = 13^2 = 169
Answer:
169
Step-by-step explanation:
We are asked to find:
f(g[h(x)])
We know that f(x) = x^2, g(x) = x + 6, and h(x) = 7
Therefore, we can begin by substituting 7 for h(x)
f(g[h(x)]), h(x)=7
f(g[7])
Now, we must find g(7). We know that g(x) is x+6
g(x)=x+6
We want to find g(7). Plug 7 in for each x.
g(7)=7+6
Add 7 and 6
g(7)=13
Substitute 13 in for g(7)
f(g[7])
f(13)
Finally, find f(13). We know that f(x)=x^2
f(x)=x^2
We want to find f(13). Plug 13 in for each x.
f(13)=13^2
13^2= 13*13= 169
f(13)=169
169
Therefore, f(g[h(x)]) is 169
Determine if the two triangles shown are similar. If so, write the similarity statement. options: A) ΔUVW ∼ ΔFGH B) The triangles are not similar. C) ΔWUV ∼ ΔFGH D) Impossible to determine.
Answer:
B (from down below) They are similar but your q does not match up with the picture
Step-by-step explanation:
to determine if two triangles are similar you have to make sure the ratios are the same. So 10 / 8 = 1.25, so all sides should have this ratio. 15 / 12 is also 1.25 so you know to sides are similar and also the triangles ARE SIMILAR. So The statement would be KMN is similar to KLP.

HELP PLEASE I REALLY NEED THE HELP ON THIS.
for questions 8 and 9, you just need to use a ruler to fine how many inches, centimeters, or millimeters each line segment is. (make sure to properly read the question to see if they’re asking for the measurement in in, cm, or mm.) i won’t be able to give you these measurements because the picture became smaller when you uploaded it, but it shouldn’t be that hard for you!
for question 10, use a ruler to draw and label your own line segment.
on 10a, draw a line segment that is 3 1/4 inches long, then label one end of the segment ‘H’ and one end ‘J’
for 10b, draw a line segment that is 5 7/16 inches long, then label one end of the segment ‘M’ and the other ‘N’.

The two middle terms are like terms, the order in which you multiply does not matter ab =ba
12 b^2 +4ab -3ab -6
12 b^2 +ab -6
The correct answer is....
A.) A 12b2+4ab-3ba-6If the degree and variables of two terms are same, then they are called like terms.
Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.
By combining like terms we get
In options B, C and D, there are no like terms, So only the expression we can simplify by combining like terms.
What is the slope of the line that passes through the points (–20, 18) and (30, 14)?
Explanation:
Use the slope formula. We subtract the y values together, and do the same for the x values as well. Subtract in the same order each time. Then you divide the two results. Reduce the fraction if possible.
m = (y2 - y1)/(x2 - x1)
m = (14 - 18)/(30 - (-20))
m = (14 - 18)/(30 + 20)
m = -4/50
m = -2/25
Answer:
[tex]-\frac{2}{25}[/tex]
Step-by-step explanation:
Slope is rise over run.
[tex]m=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (–20, 18) and (30, 14).
[tex]m=\frac{14-18}{30+20}=\frac{-4}{50}=-\frac{4}{50}=-\frac{4/2}{5/2}=\boxed{-\frac{2}{25}}[/tex]
The slope is -2/25.
