What equation can be used to solve for x
60Step-by-step explanation:
You are a business developer and charge $45 for a site visit plus additional $24 per hour for each hour you spend training employees. Write and solve an equation to determine how many total hours you have to work to earn $810 working hours at two separate businesses.
Answer: [tex]28.3\ hr[/tex]
Step-by-step explanation:
Given
Charge of the site visit [tex]\$45[/tex]
Additional charge per hour is [tex]\$24\ \text{per hour}[/tex]
He eaned [tex]\$810[/tex]
Suppose he worked for x hours
[tex]\therefore 810=45+24x\\\text{On solving}[/tex]
[tex]\Rightarrow 765=24x\\\Rightarrow x=28.3\ hr[/tex]

[tex] \boxed{(6, -3)} [/tex]
Step-by-step explanation:
Given the ratio 5:3
and Points A and B where A is located at (-6, 3), and B is located at (26, -13).
Let point A be [tex] (x_{1}, y_{1}) [/tex], and let point B be [tex] (x_{2}, y_{2}) [/tex].
(-6, 3) → [tex] (x_{1}, y_{1}) [/tex].
(26, -13) → [tex] (x_{2}, y_{2}) [/tex].
Let 5 be n, and 3 be m.
5:3 → n:m
[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex].
To solve, just substitute these variables into the expressions of these coordinates to get the answer.
[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex] →
[tex] (\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)}) [/tex] →
[tex] (\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)}) [/tex] →
[tex] (\frac{-30 + 78}{8}, \frac{15+ -39}{8}) [/tex] →
[tex] (\frac{78 – 30}{8}, \frac{15 – 39}{8}) [/tex] →
[tex] (\frac{48}{8}, \frac{-24}{8}) [/tex]
→
[tex] (\frac{6}{1}, \frac{-3}{1}) [/tex]
→
[tex] (6, -3) [/tex].
Thus the coordinates of B are:
[tex] \boxed{(6, -3)} [/tex]
Answer:
Step-by-step explanation:
AB:BC::5:3
let the coordinates be (x,y)
[tex]x=\frac{nx1+mx2}{m+n} \\=\frac{3(-6)+5(26)}{5+3} \\=\frac{-18+130}{8} \\=\frac{112}{8} \\=14\\y=\frac{ny1+my2}{m+n} \\=\frac{3(3)+5(3)}{5+3} \\=\frac{9+15}{8} \\=\frac{24}{8} \\=3\\[/tex]
coordinates of B are (14,3)

Find the value of sin^-1(4pi/5)
Answer:
No value because 4π/5 exceeds the domain
Step-by-step explanation:
The domain and range of sin^-1(x) is a domain of [-1,1] and a range of [-π/2,π/2]
Since 4π/5>1, this exceeds the domain and therefore has no value.
The diameter of a human hair is about 0.00067 inches in length. How is this length
expressed in sclentific notation?
A 6.7 x 10 4in.
B 67 x 10 4 In.
C 6.7 x 10-4 in.
D 67 x 10-4 in.
Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.

The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.
1) Hank is looking to sell his motorcycle. He compiles these prices from the newspaper for bikes just like his
$2,000; $ 16,900; $15,100; $14,500; and $17,000. Is it more reasonable for Hank to use the mean or the
median to get a reasonable estimated price for his bike?
Answer:
The median
Step-by-step explanation:
If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.

cosx (2 sinx+1)=0
Answer:
x = pi/2 and 11pi/6
Step-by-step explanation:
Given the trigonometry expression
cosx (2 sinx+1)=0
This can be written in two forms as;
cosx = 0 and 2sinx + 1 = 0
If cos x = 0
x = arccos0
x = 90degrees
x = pi/2
Similarly
2sinx + 1 = 0
2sinx = -1
sinx = -1/2
sinx =-0.5
x = aarcsin(-0.5)
x = -30
Since sin is negative in the third and 4th quadrant
x = 270 + 30
x = 330degrees
x = 330pi/180
x = 11pi/6

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257

For problems 11 and 12, find the area of the figure. Round your answer to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
11)
A= (B x H)/2
A= (2.9x3.2)/2= 4.64cm²
12)
A= (B+b)H /2
A= (12+10)5.6 /2 = 61.6in
Answer:
I think that the answer might be 9.30 for the first one and the second one I think is 670.
Step-by-step explanation:
To find the area, you have to multiply the height and width for the two figures.
3.2 × 2.9 = 9.28
12 × 10 × 5.6 = 672
I think you round those to the nearest tenth. 9.28 would be 9.30 and 672 would be 670. I hope this answers your question.

Each color is a
different digit
eren
Answer:
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
Step-by-step explanation:
P.S - The exact question -
Given - The diagram
To find - The number that represent Red, Silver and Blue color.
Proof -
Let the number printed in red color = r
Let the number printed in silver color = s
Let the number printed in blue color = b
Also,
Given that the equation is -
b s r
b s r
+ b s r
= r r r
Now,
We have to think of a number that if we add the last digit of the number gives the same last digit.
Bt inspection ,
the number would be 5
Because 5 + 5 + 5 = 15
Lat place of the equation is same
So,
The number printed on red color = 5
⇒r = 5
So, the equation becomes
b s 5
b s 5
+ b s 5
= 5 5 5
Now,
We have to think of a number whose last digit add up to 3 + 1 gives the last digit number 5 ( we add 1 because by adding 5 + 5 + 5 , we get 15 so we write the last digit 5 and 1 goes to the remainder and that remainder 1 will add up in the next number addition)(addition rule)
i.e.
s + s + s + 1 = number whose end digit is 5
By inspection,
The number would be 8
because 8 + 8 + 8 + 1 = 25
So,
we get
s = 8
So, the equation becomes
b 8 5
b 8 5
+ b 8 5
= 5 5 5
Now,
By same process , we will find the number of blue color
By inspection the number on blue color = 1
∴ we get
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
and the equation is -
1 8 5
1 8 5
+ 1 8 5
= 5 5 5
