Answer:
3 °F/h
Step-by-step explanation:
The rate per hour of temperature change = change in temperature per measurement/change in time per measurement.
Now, the change in temperature per measurement is constant = 3/4 °F and the change in time per measurement is constant = 15 minutes = 15/60 h = 1/4 h.
So, rate per hour of temperature change = change in temperature per measurement/change in time per measurement
= 3/4 °F ÷ 1/4 h
= 3/4 °F × 4/h
= 3 °F/h
So, the rate per hour of temperature change is 3 °F/h
for f(x) =4x+1 g(x)=x²-5, find (f•g)(x)
Step-by-step explanation:
The composite function (f o g)(x)
= f(x² - 5)
= 4(x² - 5) + 1
= 4x² - 19.
4x² - 19

QS is an angle bisector, what is the value of x?
Answer:
The value of x is 16
Step-by-step explanation:
The angle Bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle
In Δ QPR
∵ QS is the angle bisector
∵ PR is the opposite side
→ By using the rule above
∴ [tex]\frac{PS}{PQ}[/tex] = [tex]\frac{SR}{RQ}[/tex]
∵ PS = x and PQ = 30
∵ PR = 40
∵ RS = PR - PS
∴ RS = 40 - x
∵ RS = 40 - x and RQ = 45
→ Substitute them in the rule above
∴ [tex]\frac{x}{30}[/tex] = [tex]\frac{40-x}{45}[/tex]
→ By using the cross multiplication
∵ x × 45 = 30 × (40 - x)
∴ 45x = 30(40) - 30(x)
∴ 45x = 1200 - 30x
→ Add 30x to both sides
∵ 45x + 30x = 1200 - 30x + 30x
∴ 75x = 1200
→ Divide both sides by 75
∴ x = 16
∴ The value of x is 16

Noel Magee purchased a micro-cut shredder at a sale price of $179.99. The regular selling price is $199.99. He also purchased a photo-smart printer at 25% off the regular price of $499.99. A. What is the markdown on the shredder? B. What is the markdown on the printer?
Answer:
a) 10% off or $20 off
b) 25% off or $124.99 off
Step-by-step explanation:
In order to find the markdown on the shredder we simply need to divide the sale price by the original price. Once we have that we subtract that decimal from 1 and multiply by 100 to get the markdown percentage. We can also subtract the original price from the sales price to get the markdown dollar value.
179.99 / 199.99 = 0.899
(1 - 0.899) * 100 = 10%
199.99 - 179.99 = $20
Now, for the printer we are provided the markdown perentage so to find the markdown dollar value we need to divide the perentage by 100 to turn it into a decimal and multiply that decimal by the regular price of the printer. We can also subtract the markdown dollar value from the original price to get the sale price...
25% / 100 = 0.25
0.25 * 499.99 = 124.99
499.99 - 124.99 = $375

Y= -2x+4 by graphing
Answer:
See attached file.
Step-by-step explanation:
This can be graphed by plugging in two distinct x values and solving each for y. That will give you two x,y coordinates to draw on the graph, which will let you trace the line defined by them.
You can get the points where the line intersects the axis by solving either variable for zero. Try giving x a value of 2 or 0 to find those.

Natalia is writing a recursive formula to represent the sequence.
8, 12, 18, 27, ...
What value should she use as the common ratio in the formula?
1/4, 2/3, 3/2, 4/1
Answer:
The answer to your equation would be 1.5.
Step-by-step explanation:
The common ratio if there exists one can be found by choosing a term and dividing by its previous term
So does 12/8=18/12=27/18? Put each into the calculator. If they are equal fractions then this sequence is geometric and has a common ratio.
Each of the fractions are equal to 1.5.
Therefore the commom ratio is 1.5.

Ed wants to build a small 800 square foot cabin on a lot that is 80 feet deep. If the building sideyard setbacks are 20 feet and the cabin is 20 feet wide, what is the square footage of the lot
Answer:
4800 ft²
Step-by-step explanation:
Given that :
Area of cabin = 800 ft²
Width of cabin = 20 feets
Side yard setback of building = 20 feets
Depth of lot = 80 feets
The cabin is a rectangle :
Area of rectangle = Length * Width
800 = length * 20
Length = 800 / 20 = 40 feets
Hence,
Width of lot = side yard + Width of cabin = (20 + 20) = 40 feets
Length of lot = depth +. Length of cabin = (80 + 40) = 120 feets
Area of lot = Length of lot * width of lot
Area of lot = 120 ft * 40 ft = 4800 ft²

Answer: x=36 degrees
Step-by-step explanation:
Angle EAF and FAB must equal 180 degrees together as all straight lines do. 36 times 3= 108 degrees so 3x=108 degrees. 36 times 2= 72 degrees so 2x=72 degrees. Therefore, 3x+2x=180 degrees.
Tire pressure monitoring systems (TPMS) warn the driver when the tire pressure of the vehicle is 28% below the target pressure. Suppose the target tire pressure of a certain car is 32 psi (pounds per square inch)
Answer:
23.04psiStep-by-step explanation:
Since we are not told what to find, we can as well find the new tire pressure after reducing to 28% of the target pressure
Given the target tire pressure = 32psi
If the tire pressure of the vehicle is 28% below the target pressure, then the pressure of the tire will be;
32 - (28% of the target pressure)
= 32 - (28% of 32)
= 32 - (0.28 * 32)
= 32 - 8.96
= 23.04psi
Hence the new tire pressure if it is 28% below the target is 23.04psi

In the figure, if m ZABD = 120°, then mZADC =
0.
Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,
[tex]\frac{\text{sin}(\angle ABD)}{\text{AD}}=\frac{\text{sin}(\angle ADB)}{AB}[/tex]
[tex]\frac{\text{sin}(120)}{35}=\frac{\text{sin}(\angle ADB)}{30}[/tex]
sin(∠ADB) = [tex]\frac{30\text{sin}(120)}{35}[/tex]
= 0.74231
m∠ADB = [tex]\text{sin}^{-1}(0.74231)[/tex]
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°

If it costs $12 to enter an amusement park and $0.50 per ride.
how would I explain in words the meaning of f(6) = 15 in context of the problem?
Answer:
In this problem, the equation is basically as follows:
F(x)=0.5x+12
where f(x) is the total cost and x represents the number of rides
F(6)= 15 means that the total cost of the amusement park when a person rides six rides is $15.

so this uses proportions.
you need to find the side BF which is proportional to the side BF.
You do:
9/6=x/42
and cross multiply
9*42=6*x
378=6x
divide by 6 on both sides
x=63
the answer is 63
Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE

Two times x is 16 more than y. The sum of x and two times y is 18.
find the value of y.
Step-by-step explanation:
We can make 2 equations as follows:
2x = y + 16 and x + 2y = 18
x + 2y = 18 is the same as x = 18 - 2y. Hence, 2(18 - 2y) = 2x = y + 16.
2(18 - 2y) = y + 16
36 - 4y = y + 16
5y = 20
y = 4.
