Step-by-step explanation:
15 quarters = 3.75
4.05 - 3.75 = 0.30
3 dimes = 0.30
sooo.
3.75 (15q) + 0.30 (3d) = 4.05

2. Divide by 4
3.multiply by w2
Third drop down: 85

Answer:
Below.
Step-by-step explanation:
To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.
The total volume = 1/2 * 4/3 π (15)^3 + π (15)^2 * 85
= 67151.5 ft^3.
Step-by-step explanation:
find the volume of a sphere with a radius of 15 ft and divide by 2 (because there is only half a sphere on top of the silo).
then add the volume of a cylinder with a radius of 15 ft and a height of 85 ft (because we need to deduct the radius of the sphere from the total height to get the height of the cylinder itself).

where:
a is the first termd is the common difference between the termsn is the total number of terms in the sequence[tex]\displaystyle \sum\limits_{k=1}^{275} (-5k+12)[/tex]

Step-by-step explanation:
Tan 150 degrees is the value of tangent trigonometric function for an angle equal to 150 degrees. The value of tan 150° is -1/√3 or -0.5774 (approx).
Find the measure of each angle indicated.
The measure of the unknown angle in the triangle is 58 degrees.
What is a triangle ?A triangle has three sides and the sum of the angles of a triangle is 180 degrees.
Triangles can be classified base on there angles and length of the sides.
Therefore,
let the length of the unknown angle = x
x + 65° + 57° = 180°
x + 122 = 180
subtract 122 from both sides
x + 122 - 122 = 180 - 122
x = 58 degrees

Doctor Jones starts an appointment every 20 minutes.
Doctor Warholm starts an appointment every 35 minutes.
The first appointment for both doctors starts at 8.30 am.
What is the next time that they have an appointment start at the same time?
The first appointment for both doctors starts at 8:30am.
To find:Next appointment that they start at same time.
Solution:For the same time same time take LCM of 20 and 35.
20= 2x2x5
35= 5×7
hcm (20,35) = 2X2X5X7 = 140
They will take appointment after 140 minutes. 1.e. 2 hours 20 minute.
so, next appoitment will be 10:50a.m.
The next time that they have an appointment start at the same time is at 10:50 a.m.
How do we calculate the appointment time start?We are given that the first appointment for both doctors starts at 8:30am while the Next appointment also started at same time but Doctor Jones starts his every 20 minutes while Doctor Warholm starts his every 35 minutes.
First stepFor the same time, take LCM of 20 and 35.
20 = 2 * 2 * 5
35 = 5 * 7
Second stepHCM (20, 35) = 2 * 2 * 5 * 7
HCM (20, 35) = 140
Hence, it will take the appointment after 140 minutes which equals to 2 hours 20 minute.
Now, from 8.30 am, the addition of the 2 hours 20 minute gives us 10:50 a.m which is the next time that they have an appointment start at the same time.

You spend a $20 per turn on a fair game to win $50 for each win. You lose the first round but win the next two rounds.
What was the net payoff?
$100
-$60
-$30
$40
The net payoff obtained during the game is $40. Option D is the correct answer.
What is net payoff?The term "net payoff" describes the profit or loss realised from a transaction or operation after deducting all costs, charges, and taxes. It is determined by deducting the total cost of the activity or investment from the total income received. A gain is shown by a positive net reward, whereas a loss is indicated by a negative net payoff.
Given that, each round cost $20, and each win gives $50.
Now, for 3 rounds the total cost is:
$20 x 3 = $60
After winning the two round the win amount is:
$50 x 2 = $100
Now, the net payoff is:
$100 - $60 = $40.
Hence, the net payoff obtained during the game is $40. Option D is the correct answer.

train station, rode on a train for 14 hours, and then took a bus.
How much time did Jerry spend riding on the bus?
Show your work.
Answer
hours
Answer:
What we know:
39 hours is the total amount of time spent on the trip.14 hours spent with both walking and the train.Our challenge:
To figure out how many __ hours were spent on the bus.Let's set up an equation,
-we'll assume that 'x' are the unknown hours spent on the bus.
The unknown hours spent on the bus plus the hours spent both on walking/and the train will equal a total of 39 hours.
So,
14 + x = 39
Solve for x;
-14 -14
x = 25, the hours Jerry spent riding on the bus is 25 hours.
Answer:
25 hours
Step-by-step explanation:
Given
It took 39 hours in total to get to his grandmother's houseWalking and train transit takes 14 hours togetherSolving
Total time = Time (walking) + Time (train) + Time (bus)39 hours = 14 hours + Time (bus)Time (bus) = 39 - 14 = 25 hoursFind the area of the circle. DO NOT ROUND
