Answer:
12 inches
Step-by-step explanation:
a^2 + b^2 = c^2
a=16
b=?
c=20
16^2 + b^2 = 20^2
256 + b^2 = 400
400 - 256 = b^2
144 = b^2
Square root 144 = b
12 = b
A cyclist rides her bike at a rate of 9 kilometers per hour. What is the rate in kilometers per minute? How many kilometers will the cyclist travel in 2 minutes
Answer: 0.15km/min and 0.3km in 2 mins
Step-by-step explanation:
Given Data:
Cyclists speed = 9km/hr
1. Some traveling 60 km/h is traveling one km/min
60/60= 1 km/min
Rate in km/min
= 9km/hr / 60min
= 3/20 km/min
= 0.15 km/min
Kilometers travelled in 2mins
= 2 / 60
= 1 / 30
= 9km/hr * 1 / 30
= 9 / 30
= 0.3 km in 2mins
Answer:
Rate(in km/min) = 0.15 km/min
Distance traveled in 2 mins = 0.3 km
Step-by-step explanation:
Rate = 9 km/hr
1 hr = 60 mins
In 60 minutes, the cyclist rides 9 km
in 1 minute, the cyclist will ride 9/60 km
Therefore, the rate in km/min = 9/60 km/min
Rate(in km/min) = 0.15 km/min
Since the cyclist rides 0.15 km in 1 min,
In 2 mins, the cyclist will ride 0.15 * 2 km = 0.3 km
Distance traveled in 2 mins = 0.3 km

Jane earns money walking dogs on the weekends. Jane charges $5 dollar sign, 5 for each dog she walks.
Complete the table for the given ratio.
Dogs Charge in dollars.
1 5
3 ?
5 ?
FIND THE ?
HURRY UP I HAVE 1 MINUTE TO SOLVE THIS
Answer:
3 dogs, $15
5 dogs, $25
Step-by-step explanation:
Jane charges $5 per dog.
When she walks 3 dogs ;
1 dog = $5
3 dogs = x
x × 1 dog = $5 × 3 dogs
x= $5 × 3 dogs/ 1 dog
x= $5 × 3 = $15
When Jane Walks 5 dogs she receives,
y= $5 × 5
y= #25.
For 3 dogs, Jane would charge $15. For 5 dogs, she would charge $25. You find these amounts by multiplying the number of dogs by the charge per dog, which is $5.
Explanation:Since Jane charges $5 for each dog she walks, you can find the charge for any number of dogs by multiplying the number of dogs by 5.
For 3 dogs, she would charge $15 (3 dogs x $5 per dog = $15).
For 5 dogs, she would charge $25 (5 dogs x $5 per dog = $25).
So, the completed table would look like this:
Dogs | Charge in dollars
1 |$5
3 |$15
5 |$25

If a sphere’s surface area is doubled, what is the corresponding change in radius?
Answer:
The radius has an increase of 41.4%
Step-by-step explanation:
We have that the surface area formula is equal to:
a = 4 * pi * r ^ 2
in this case if you assume an area of 100 and we calculate the radius it would be:
100 = 4 * pi * r ^ 2
we solve for r:
r ^ 2 = 100/4 * pi
r ^ 2 = 100 / (4 * 3.14)
r ^ 2 = 7.9617
r = 2,822
now if we double the area, that is 200:
r ^ 2 = 200 / (4 * 3.14)
r ^ 2 = 15.9236
r = 3,990
So the change of the radius would be:
3.99 / 2,822 = 1,414
That is to say that the radius has an increase of 41.4%

Delisa is designing a website that will be viewable on both computers and mobile devices, so the website as it is seen on a mobile device is proportional to the website as it is seen on a computer. The diagonal of Delisa's computer monitor is 21 inches, and the diagonal of Delisa's tablet is 9.1 inches. If an image is 19 centimeters wide on the website when it's displayed on Delisa's computer, how wide should the image be on the tablet? Round to the nearest tenth of a millimeter, if necessary.
Final answer:
To find the width of the image on the tablet, set up a proportion using the diagonals of the computer monitor and the tablet. Solve for the unknown width using cross multiplication.So,on tablet it would be 0.84mm.
Explanation:
To determine the width of the image on the tablet, we can use a proportion based on the diagonals of the computer monitor and the tablet. The proportion can be set up as follows:
Computer Diagonal / Tablet Diagonal = Computer Width / Tablet Width
Substituting the given values, we have:
21 inches / 9.1 inches = 19 centimeters / x
Cross multiplying and solving for x, we get:
x = (9.1 inches * 19 centimeters) / 21 inches
Converting the units, the width of the image on the tablet should be approximately 8.43 centimeters=0.84mm
A silo is a composite of a cylindrical tower with a cone for a roof. Find the volume of the silo if the
radius of the base is 120 feet, the height of the roof is 25 feet, and the height of the entire silo is 130
feet.
Answer:
5127079.21 cubic feet
Step-by-step explanation:
The silo is in the shape of a cylinder and a cone.
The volume of the silo will be the sum of the volumes of the cylinder and the cone.
Therefore, its volume is:
[tex]V = \pi r^2h + \frac{1}{3} \pi rH[/tex]
where r = radius of cylinder and cone
h = height of cylinder
H = height of cone
The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:
130 - 25 = 105 feet
Therefore, the volume of the silo is:
[tex]V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3[/tex]
The volume of the silo is 5127079.21 cubic feet.

Either enter an exact answer in terms of n pi or use 3.14 for n pi and enter as a decimal.
* This is from Khan academy and the lesson is (Circumstance of part of circles)*
Answer: 1.57
Step-by-step explanation:
When solving for the arc you have to find the circumference.
For circumference you'll need the diameter which is 2x the radius.
So, your equation would be
1/4{(pi)(2)} = x
or
1/4{(3.14)(2)} = x
To Solve:
3.14 times 2 equals 6.28
Divide by 4 or multiply by 1/4 to get 1.57
Not sure if this is correct, I haven't learned the topic myself, but this week's to be there most reasonable way to look at it. For me anyway.
The arc length of a partial circle can be calculated using the formula Arc length = (θ/360) * 2πr, where 'θ' is the angle of the sector in degrees and 'r' is the radius of the circle. This is applicable in high school Mathematics.
Explanation:The subject of your question is the arc length of a partial circle, a concept in Mathematics. The arc length of a partial circle can be calculated using the formula: Arc length = (θ/360) * 2πr, where 'θ' is the angle of the sector in degrees and 'r' is the radius of the circle.
For instance, if a circle has a radius of 8 units and the angle of the sector is 60 degrees, the arc length can be calculated as follows: Arc length = (60/360) * 2 * 3.14 * 8 = 8.38 units (in terms of 3.14 for n π). Using n π, the exact answer would be expressed as: Arc Length = 4π/3 units.

A pizza with radius 7 in. is cut into 12 equal-sized pieces. What is the area of each piece? Round to the nearest hundredth of an inch.
Each pizza slice has an area of approximately 12.82 square inches, rounded to the nearest hundredth.
To find the area of each pizza slice, we first need to find the total area of the pizza and then divide it by the number of slices.
The formula for the area of a circle is [tex]\( A = \pi r^2 \)[/tex], where [tex]\( \pi \)[/tex] is approximately 3.14 and r is the radius of the circle.
Given that the radius of the pizza is 7 inches, we can calculate the total area of the pizza:
[tex]\[ A_{\text{total}} = \pi \times (7)^2 \]\[ A_{\text{total}} = 3.14 \times 49 \]\[ A_{\text{total}} \approx 153.86 \text{ square inches} \][/tex]
Now, to find the area of each pizza slice, we divide the total area by the number of slices (12):
[tex]\[ A_{\text{each slice}} = \frac{A_{\text{total}}}{12} \]\[ A_{\text{each slice}} \approx \frac{153.86}{12} \]\[ A_{\text{each slice}} \approx 12.82 \][/tex]
So, the area of each pizza slice is approximately 12.82 square inches.

Finn started a savings account with $5,000 and earns 3% simple interest for 5 years. How much interest will be earned over the 5 years? a) 15,000 b)759 c)3000 d)5015
Answer:
the answer is b. (since you accidentally typed 759 not 750)
Step-by-step explanation:
The formula for simple interest is
A = P (1 + rt)
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
and the interest is going to be 750 after you plug it in, they are not asking for the amount of money total, but the amount of interest earned.
3 percent simple interest for 5 years means you are getting 0.03 percent of money from the 5,000 initial value and for 5 years. The total interest is $750.
I hope this helped! :)
