Answer:
[tex] V_{total} = 26460 \pi~cm^3 [/tex]
[tex] V_{total} = 83127~cm^3 [/tex]
Step-by-step explanation:
The solid is made up of 2 cones and a cylinder.
Upper cone:
radius = 21 cm
height = h_1 = 70 cm - 35 cm = 35 cm
Cylinder:
radius = 21 cm
height = h_2 = 35 cm
Lower cone:
radius = 21 cm
height = h_3 = 40 cm
[tex] V_{total} = V_{upper~cone} + V_cylinder} + V_{lower~cone} [/tex]
[tex] V_{total} = \dfrac{1}{3} \pi r^2 h_1 + \pi r^2 h_2 + \dfrac{1}{3} \pi r^2 h_3 [/tex]
[tex] V_{total} = \dfrac{1}{3}(\pi)(21~cm)^2(35~cm) + (\pi)(21~cm)^2(35~cm) + \dfrac{1}{3}(\pi)(21~cm)^2(40~cm) [/tex]
[tex] V_{total} = \dfrac{1}{3}(\pi)(441~cm^2)(35~cm) + (\pi)(441~cm^2)(35~cm) + \dfrac{1}{3}(\pi)(441~cm^2)(40~cm) [/tex]
[tex] V_{total} = (147~cm^2)(35~cm)(\pi) + (441~cm^2)(35~cm)(\pi) + (147~cm^2)(40~cm)(\pi) [/tex]
[tex] V_{total} = 5145\pi~cm^3 + 15435\pi ~cm^3 + 5880\pi~cm^3 [/tex]
[tex] V_{total} = 26460 \pi~cm^3 [/tex]
[tex] V_{total} = 83127~cm^3 [/tex]
Martha earns $15 per hour for babysitting. The parents always giver her a $5 tip.
What is the slope of this situation?
Enter the correct answer in the box.
? Dollars per hour
Answer:
$3.25 multiplied by the hour
Step-by-step explanation:
The slope of the situation if, Martha earns $15 per hour for babysitting, The parents always give her a $5 tip is $15 per hour.
What is the slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Given:
Martha earns $15 per hour for babysitting,
The parents always give her a $5 tip,
The equation for the total money earned by Martha can be written as shown below,
The total money earned = Money per hour for babysitting × number of hours + tip
Assume the total money earned is y, the number of hours is x,
y = 15x + 5
As you can see, the above equation is in slope intercept form,
Slope = $15 per hour

Solve 3(x + 1) = −2(x − 1) − 4
-1
1
-3
5
Answer:
x = -1
Step-by-step explanation:
3(x + 1) = -2(x - 1 ) - 4
use the distributive property to get rid of the parentheses. on -2 and -1 they cancel each other out so it becomes + 2. now you have:
3x + 3 = -2x + 2 - 4 (+2 and -4 are like terms so they become -2. so technically its 3x + 3 = -2x -2)
get +3 on the other side by subtracting it from itself and then subtracting it from -2 so it becomes -5.
3x = -2x - 5
get -2x on the other side by adding 2x to itself then adding 2x to 3x so it becomes 5x
5x = -5
divide 5 from -5 and you get x = -1

Emily drives 186 miles in 3 hours. What is her average speed? Give your answer in mph
Emily's average speed will be 62 mph for the trip
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
Emily travels 186 miles in three hours.
To determine Emily's average speed, we can divide the distance she traveled by the time it took her to travel that distance. Her average speed would be:
⇒ average speed = distance / time
⇒ average speed = 186 miles / 3 hours
Apply the division operation, and we get
⇒ average speed = 62 mph
This is Emily's average speed for the trip.

Explanation:
Think of z as having 1 zebra
2z means we have 2 zebras
If we started with 2z, and subtracted off 2z, then we're left with 0 zebras. We write this as 0z or just 0 since 0 times anything is 0.
---------
As another example:
Let's say we wanted to simplify 5z - 2z
Well that's the same as saying "5 zebras take away 2 zebras". We'd be left with 3 zebras because 5-2 = 3
Since 5-2 = 3, this leads to 5z-2z = 3z. The difference is that I tacked 'z's onto each number.
A phone company has two long distance calling plans. The first plan is $25 per month plus $0.01 per minute of long distance calling after the first 100 minutes. The second plan is $10 per month plus $0.05 per minute of long distance calling.
How many minute of long distance calls will it take for the plans to cost the same amount?
Answer:
286 minutes
Step-by-step explanation:
can you give brainlest or good review
Answer:
Hello!
Let's call X to the number of minutes of long-distance calls you plan to make.
The cost of plan A is given by 25%2B0.05X
The cost of plan B is given by 5%2B0.12X
Plan B is advantageous when its cost is lower than plan A's. Therefore, we set the inequality
5%2B0.12X+%3C+25%2B0.05X
And then solve for X. This will give us the range of minutes for which B is more convenient.
Subtract 5 from both sides of the inequality to get:
0.12X+%3C+20%2B0.05X
Now subtract 0.05X:
0.12X+-+0.05X+%3C+20
0.07X%3C20
Finally, divide by 0.07 to get:
X+%3C+20%2F0.07
X++%3C+285.71
So plan B is advantageous if you plan to use less than 286 minutes of long distance calls.

<E=<K
DE=JK
Step-by-step explanation:
The first two answers are correct because they are corresponding. One way of solving is going through each answer and comparing the measurements, if they are congruent then the statement is true, if not it is false.
1) <E=88 and <K=88, since 88=88 this is a true statement.
2) DE=14 mi and JK=14 mi, since 14=14 this is a true statement.
3) CD=14 mi and KL=25 mi, since 14[tex]\neq[/tex]25 this is a false statement.
4) EB=25 mi and MJ=14 mi, since 25[tex]\neq[/tex]14 this is a false statement.
