A dog has a 25 ft leash attached to a corner where a garage and fence meet. When the dog pulls the leash tight and walks from the fence to the garage, the arc the leash makes is 74.3 ft. What is the measure of the angle between the garage and fence, in degrees?
150 degrees
170 degrees
190 degrees
107 degrees
Answer: [tex]170^{\circ}[/tex]
Step-by-step explanation:
Given
The dog has a 25 ft leash
Arc length is 74.3 ft
Arc length is given by
[tex]l=\dfrac{\theta }{360^{\circ}}\times 2\pi r[/tex]
here, r=25 ft
l=74.3 ft
Put the values
[tex]\Rightarrow 74.3=\dfrac{\theta }{360^{\circ}}\times 2\pi \times 25\\\\\Rightarrow \theta =170.2^{\circ} \approx 170^{\circ}[/tex]
The measure of the angle is [tex]170^{\circ}[/tex]

Answer:
4W = 25
Step-by-step explanation:
The hanger is balanced, so each side must have the same quantity.
There are 4W on one side and 25 on the other. That means that 4W and 25 must equal each other in order to keep the hanger balanced.
Answer:
We can see on one side there is 4 w's and on the other side is a 25, because the hanger is balanced these must be equal:
We can form the equation:
4w = 25
w = 6.25

An office building has 123 floors. The floors are 3.8m apart.
A lift goes from floor 32 to the top. How far does it travel?
Answer:
345.8 meters
Step-by-step explanation:
Given that :
Distance between floors = 3.8 m apart
Moving from floor 32 to the top
Number of floors moved = 123 - 32 = 91 floors
Distance traveled :
Distance between floors * number of floors moved
3.8 m * 91 = 345.8 meters

Answer:
____1260 ____Since we have to predict, we can use ratios to help us solve this.
12 said yes out of 72 randomly chosen, SO,
if 210 would say yes (goes to play), how many is total??
12 is to 72 AS 210 is to HOW MUCH (let it be x)??
We can setup ratio, cross multiply, and solve for x:
= 12/72= 210/x
= 12x = 210*72
=12x = 15,120
=x = 15,120/12
=x =1260Change 10 m/s in km/h

4.5 units
(Choice B)
5.4 units
(Choice C)
9.1 units
(Choice D)

Answer:
The answer is B 5.4 units
Step-by-step explanation:
The approximate value of PQ in the right angle triangle is 5.4 units.
Right angle triangleA right angle triangle has one of its angles as 90 degrees. Therefore, the sides can be found by trigonometric ratios.
Hence,
sin 50 = opposite / hypotenuse
sin 50 = PQ / 7
cross multiply
PQ = 7 sin 50°
PQ = 7 × 0.76604444311
PQ = 5.36231110183

Find the volume of the square pyramid. Round your answer to the nearest hundredth
Answer:
60.26yd³
Step-by-step explanation:
Since we are not given the diagram, let us assume that;
Length of the base = 5.4yd
Height of the pyramid = 6.2yd
volume of the square pyramid = BH/3
B is the base area = L^2
B = 5.4²
B = 29.16yd²
H = 6.2yd
Get the volume
volume of the square pyramid = 29.16*6.2/3
volume of the square pyramid = 180.792/3
volume of the square pyramid = 60.26yd³
Hence the volume of the square pyramid to nearest hundredth is 60.26yd³

He price of a computer component at the QRCC bookstore is decreasing at a rate of 2.25% per year. Decide whether this decrease is linear or exponential.
Answer:
The decrease is exponential.
Step-by-step explanation:
An exponential decrease is something like:
f(x) = A*(r)^x with 0 < r < 1
A linear decrease is something like:
g(x) = -a*x + b with a > 0
First ai general formula.
If you have a quantity Q, decreased by an X%, the new quantity will be:
New Quantity = Q - Q*(X%/100%)
Now let's look at the question:
Suppose that the original price of the computer component is K
And the price as a function of the year is P(y)
Then we know that, in the year zero, the price is K.
P(0) = K
One year after, the price decreases by 2.25%
Then:
P(1) = K - K*(2.25%/100%) = K*(1 - 0.0225)
After another year, we will have another decrease of 2.25%
Then:
P(2) = K*(1 - 0.0225) - K*(1 - 0.0225)*(2.25%/100%)
P(2) = K*(1 - 0.0225)*(1 - 0.0225) = K*(1 - 0.0225)^2
We already can see the pattern, we can expect that in the year y, the price of the component will be:
P(y) = K*(1 - 0.0225)^y
This clearly is an exponential decrease.
