Hello!
First, let's write some important information:
• v, = 12 ft/s
,• r, = 1.5 ft
Knowing it, let's replace these values in the formula below to obtain w:
\(\begin{gathered} v=r\cdot w \\ 12=1.5\cdot w \\ 1.5w=12 \\ w=\frac{12}{1.5} \\ w=8 \end{gathered}\)So, w = 8.

Find three consecutive numbers whose sum is 1020
Answers
what's up? the answer to this is 339+340+341
best of luck with your studies
Answer: 339 + 340 + 341 = 1020
Step-by-step explanation:
3X + 3 = 1020
3X + 3 - 3 = 1020 - 3
3X = 1017
3X/3 = 1017/3
X = 339
Which means that the first number is 339, the second number is 339 + 1 and the third number is 339 + 2. Therefore, three consecutive integers that add up to 1020 are 339, 340, and 341.

Answers
Answer: 803.84cm3
Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.
To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.
4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.
Now, we have the area of the circle. 50.24cm squared!
The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,
16cm x 50.24cm squared = 803.84cm cubed.
The volume of the can of soup is 803.84cm cubed.

x-2=-3x+2 pls show how to fully solve it
Answers
Answer:
x = 1
Step-by-step explanation:
One thing that is necessary to learn this is that whatever you do to one side, you must do to the other. If you substract 2, you must substract 2 from both sides.
Here are all the steps:
x - 2 = -3x + 2
x = -3x + 4 (by adding 2 to both sides)
4x = 4 (by adding 3x to both sides)
x = 1 (by dividing both sides by 4)
Hope this helps!
Answer:
\(x=1\)
Step-by-step explanation:
Add \(2\) to both sides of the equation:
\(x-2=-3x+2\)
\(x-2+2=-3x+2+2\)
Simplify:
Add the numbers:\(x\)\(-2+2=-3x+2+2\)
\(x=-3x+2+2\)
Add the numbers:\(x=-3x+2+2\)
\(x=-3x+4\)
\(x=-3x+4\)
Add \(3x\) to both sides of the equation:
\(x=-3x+4\)
\(x+3x=-3x+4+3x\)
Simplify:
Combine like terms:\(x+3x=-3x+4+3x\)
\(4x=-3x+4+3x\)
Combine like terms:\(4x=-3x+4+3x\)
\(4x=4\)
\(4x=4\)
Divide both sides of the equation by the same term:
\(4x=4\)
\(\frac{4x}{4} =\frac{4}{4}\)
Simplify:
Cancel terms that are in both the numerator and denominator:\(\frac{4x}{4} =\frac{4}{4}\)
\(x=\frac{4}{4}\)
Divide the numbers:\(x=\frac{4}{4}\)
\(x=1\)

everything at a store is on sale. The store offers a 25% discount. The regular price of a t-shirt is 20%. What is the discount price? Please help me.
Answers
The discount price of the shirt will be $15.
How to calculate the price?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
From the information, the store offers a 25% discount and the regular price of a t-shirt is $20. Therefore, based on the information illustrated, the main points to note will be:
Discount = 25%
Regular price = $20.
In this case, the discount price will be the difference between the regular price and the discount.
The discount price will be:
= Regular price - Discount
= $20 - ($20 × 25%)
= $20 - $5
= $15
The price is $15.

If you increase______and _____then you will increase the objects amount of potential energy. a. mass, speed b. mass, velocity c. mass, height d. mass, acceleration
Answers
The correct answer is c. mass, height.
If you increase the mass of an object and raise it to a higher height, you will increase its amount of potential energy. Potential energy is directly proportional to both mass and height.
The potential energy of an object in a gravitational field is given by the equation:
Potential Energy = mass * gravitational acceleration * height
By increasing the mass (m) and the height (h), the potential energy (PE) of the object increases:
PE ∝ m * h
Therefore, increasing the mass and height of an object will increase its potential energy.

25. Congruent (by the HL theorem)

=============================================
Explanation for problem 23.
Check out figure 1 shown below.
I have marked the given diagram with light blue and light pink to show which angles are congruent.
Because lines UN and TC are parallel, we know the following alternate interior pairs are congruent.
angle UNC = angle TCN (light blue)angle UNL = angle TCH (light pink)Therefore, we can establish one link of paired congruent angles of the triangles LNU and TCH. However, we cannot determine any other angle pairings. Why not? Because we don't know if segment UL is parallel to segment TH. If they were parallel, then we could establish something like angle LUN = angle CHT as one alternate interior pairing.
But again, we don't know if UL is parallel to TH. The arrow markers aren't shown for these segments.
Therefore, we simply don't have enough information to determine if the triangles are similar or congruent.
----------------------------------------
Explanation for problem 25.
Luckily this problem will provide sufficient info to prove the triangles KSR and ISR are congruent.
We start with the given info that KR = SI due to the identical tickmarks. This represents one node in the flowchart (see figure 2).
Another node is angle RKS = angle RIS because both are right angles, aka 90 degree angles.
A third node is SR = SR because of the reflexive property.
Those three nodes then feed into the final conclusion node that triangle KSR = triangle ISR. The reasoning is "HL theorem" where HL = hypotenuse leg. This theorem works for right triangles only.
Take note how I structured the proof so that it flows from top to bottom. The three nodes side by side are related so they share the same row.
There are many other ways to make the flowchart, so don't feel obligated to use this format. Use whatever works best for you.
Which is longer 5 meters or 400 millimeters?
a. 400 millimeters
b. 5 meters
c. both a and b are correct.
d. both a and b are incorrect
Answers
Answer:
b. 5 meters
Step-by-step explanation:
1 meter = 1000 millimeters
5 meter = 5000 millimeters
Which is longer 5 meters or 400 millimeters?
5000 > 400
So, the answer is b. 5 meters.
This conversion can be understood by the prefix “milli” in millimeter, as “milli” means 1/1000. So, millimeter means 1/1000 of a meter or 10^-3meters.
So, let’s multiply the conversion by 5 since we want to determine if 5 meters is longer than 400mm.
Conversion, where m=meter and mm=millimeter
1m=1,000mm
Since we have an equal (balanced) relationship, if we increase one quantity by 5 times, we must do the same for the other to maintain equality (balance).
1m•5=1,00mm•5
5m=5,000mm
Therefore, 5m is longer than 400mm since 5m=500mm and 500mm>400mm.
Answer: 5 meters is longer

Now,
The equation of a line.
y = mx + c
The line passes through points (3, 4) and (5, 7).
m = (7 - 4) / (5 - 3)
m = 3/2
Slope = 3/2 _____(1)
Now,
(3, 4) = (x, y)
4 = 3/2 x 3 + c
4 = 9/2 + c
c = 4 - 9/2
c = (8 - 9) / 2
c = -1/2
y-intercept = -1/2 ____(2)

Sure, here is a more casual and friendly way to explain how to calculate the weighted dollar amount of the savings account:
"Hey there! To find out the weighted dollar amount of the savings account, you just need to do a little math. First, multiply the amount invested in the savings account by the return on investment (ROR). Then, divide that number by the total ROR for all investments.
So, if you have $2,700 invested in the savings account and it has an ROR of 3.6%, the weighted dollar amount of the savings account would be:
($2,700 * 3.6%) / (3.6% + 1.8% + 13.6% - 1.2%) = $104.04
