Answer:
$760
Step-by-step explanation:
Set up an equation:
Variable x = regular price
34/100 = 258.40/x
Cross multiply
34 × x = 100 × 258.40
34x = 25,840
Divide both sides by 34
x = 760
Check your work:
760 × 34%
Convert the percentage into a decimal:
760 × 0.34
$258.40
Correct!
Find h(3) using the graph
Answer:
h(3) = 2
Step-by-step explanation:
h(3) -- "h of 3" -- is asking for the value of the function at x = 3. Go to 3 on the x-axis, then go up to the graph. Look at the y-coordinate of the point (see the attached image).

Step-by-step explanation:
a cruise ship heads due west from a port 3 miles directly south of San Francisco. If the ship is travelling at a constant rate of 17 mph, how fast is the distance between the ship and san francisco changing 1 hour after leaving port
Answer:
16.7
Step-by-step explanation:
speed is constant at 17 mph
Distance covered after one hour = 17 miles
Distance between port and San Francisco = 3 miles
Speed at which distance changes 1 hour after leaving port :
r² = 17² - 3²
r² = 289 - 9
r = √280
r = 16.733
= 16.7 (nearest tenth )

Answer:
1. Arc BC = 78°
2. Arc ABC = 180°
3. Arc ADB = 258°
4. Arc EC = 102°
Step-by-step explanation:
Question 1 explanation: Since ∠AFE and ∠CFB are vertical angles, that means their angle measure is equal, so Arc BC has an angle measure of 78°.
Question 2 explanation: Because AC is the diameter of circle F, this means that the angle measure of Arc ABC is 180°.
Question 3 explanation: Since the angle measure of AC is 180° and ∠AFE and ∠EFD are 78° and 54° respectively, that means Arc DFC has an angle measure of 48°. Because you already know ∠CFB is 78°, that means Arc ADB has an angle measure of 258°.
Question 4 explanation: You already know Arc DFC is 48°, so Arc EC has an angle measure of 102°.

What is the value of z?
No links please!!
9514 1404 393
Answer:
z = 14.4
Step-by-step explanation:
The angle bisector divides the sides proportionally.
z/12 = 6/5 . . . . . . . . . write a proportion*
z = 12(6/5) = 72/5 . . . . . multiply by 12
z = 14.4
_____
* We consider the proportion easier to solve if the unknown is in the numerator. Then the solution is found by multiplying the equation by that denominator.

Answer / Explaination:
An equation that represents this problem is b = 52h.
A linear model that represents this equation would look as such (see below)
To predict how many boxes would be produced after an 8 hour shift, you can look at the graph (see additional attatchement) or substitute 8 in for h in the equation.
b = 52(8)
b = 416

A carpenter purchased 50 ft of redwood and 80 ft of pine for a total cost of $277. A second purchase, at the same prices, included 90 ft of redwood and 60 ft of pine for a total cost of $381. Find the cost per foot of redwood and of pine.
Answer:
Let R = cost per foot of redwood, and
let P = cost per foot of pine.
The 1st sentence gives us 60 ft * R + 90 ft * P = $303, and
the 2nd sentence gives us 90 ft * R + 60 ft * P = $357.
So this is two equations and two unknowns, so we should be able to solve these.
Solve the first equation for P: 60 ft * R + 90 ft * P = $303
Subtract 60 ft * R from both sides of the equation: 90 ft * P = $303 - 60 ft * R
Now divide both sides of the equation by 90 ft: P = ($303 - 60 ft * R) / 90 ft = $101 / 30 ft - 2/3 * R
Next, substitute P into the second equation: 90 ft * R + 60 ft * P = $357
so we then have 90 ft * R + 60 ft * [$101 / 30 ft - 2/3 * R] = $357.
Now solve for R (remember, parentheses, exponents, multiplication and division, addition and subtraction):
90 ft * R + [$202 - 40 ft * R] = 50 ft * R + $202 = $357, or 50 ft * R = $155; so R = $155 / 50 ft = $3.10 / ft.
Now we can substitute this value for R into the first equation and solve for P: 60 ft * R + 90 ft * P = $303
so we then have 60 ft * $3.10 / ft + 90 ft * P = $303, or $186 + 90 ft * P = $303.
Subtracting $186 from both sides of the equation, and then dividing by 90 ft, we have P = $1.30 / ft
So P = $1.30/ft, and R = $3.10/ft.
To check this answer, plug both into the second equation:
90 ft * R + 60 ft * P = $357
90 ft * $3.10/ft + 60 ft * $1.30/ft = $279 + $78 = $357

Triangle B is the same shape as Triangle A with a scale factor of ſ. That means each side length is the side length of Triangle A. The perimeter of Triangle B is 30 cm.
Use the diagrams to help you write an equation to find the side lengths of Triangle A.
Answer:
that description is already wrong. you must have mistyped something here. please read your own problem description again and then try again. if each side length of triangle B is the side length of triangle A, then they do not only share the same shape (= angles), but they are identical, and the scale factor is simply 1.
I think what you mean is that every side length of B correlates to the side lengths of A by the factor f.
Step-by-step explanation:
what that means :
side a of A = f × side a of B
side b of A = f x side b of B
side c of A = f x side c of B
perimeter of A = f x perimeter of B
for any more details there has to be more information.

A young entrepreneur wants to set up a lemonade stand at a busy intersection. Customers arrive at a rate of 38 customers per hour according to a Poisson distribution. Customers will be served at the average rate of 58 customers per hour with exponential service times. What is the average utilization rate (%) of the entrepreneur
Answer:
65.5%
Step-by-step explanation:
Arrival rate, λ = average number of customers per hour = 38
Servive rate, μ = number of customers attended to per hour = 58
Utilization factor, ρ = λ / μ
ρ = 38 / 58
ρ = 0.6551724
Utilization rate (%) = 0.6551724 * 100% = 65.5%

The area of a triangle is 24 square inches. What is the height of the triangle if the base length is 4 inches? (5 points) 6 inches 8 inches 12 inches 20 inches
9514 1404 393
Answer:
12 inches
Step-by-step explanation:
The area is given by the formula ...
A = 1/2bh
Fill in the given values and solve for the height.
24 in² = 1/2(4 in)h
h = (24 in²)/(2 in) = 12 in
The height of the triangle is 12 inches.
Answer:
12 inches
Step-by-step explanation:
Area = [tex]\frac{1}{2}bh[/tex]
24 = [tex]\frac{1}{2} * 4 * h[/tex]
24 = 2h
h = 12 inches
