Step-by-step explanation: What we want to do is to get x on one side. First, we subtract 16 on both sides, leaving us with:
[tex]|x+2| + 16-16 = 14-16[/tex]
Then, we subtract two on both sides, giving us:
[tex]|x+2-2|=-2-2[/tex]
That leaves us with:
[tex]|x| = -4[/tex]
HOWEVER
Since those lines mean that x MUST be positive, that means that x has no value, and this has no solutions.
A city is planning to replace one of its water storage tanks with a larger one. The city's old tank is a circular night with a radius of 12 feet and a volume of 10,000 cubic feet. The new tank is a right circular cylinder with a radius of 15 feet and the same height as the old tank. What is the maximum number of cubic feet of water in the new storage tank will hold?
Answer: 15,625 ft³
Step-by-step explanation:
You need to use the formula for calculate the volume of a cylinder:
[tex]V=r^2h\pi[/tex]
Where r is the radius and h is the height.
You know the radius and the volume of the old tank, therefore you can find the height as following:
[tex]10,000=(12)^2h\pi\\\\h=\frac{10,000}{(144)\pi}ft[/tex]
You know that the radius of the new tank is 15 feet and it has the same height as the old tank. Therefore, you can substitute h into the first equation for calculate the volume of a cylinder, to find the maximum number of cubic feet of water that the new storage tank will hold:
[tex]V=(15ft)^2(\frac{10,000}{(144)\pi}ft)\pi=15,625ft^3[/tex]
Answer:
15625 cubic feet
Step-by-step explanation:
Please help with function homework.
The maximum height occurs at the vertex found using t = -b/2a
The time = t=-20/2*-5 = -20/-10 = 2 seconds.
Now replace t with 2 in the equation to solve for the height:
h(t) = -5t^2 +20t +1
h(2) = -5(2)^2 +20(2) +1
h(2) = -5(4) + 40 + 1
h(2) = -20 + 41
h(2) = 21 meters.
Maximum height was 21 meters at 2 seconds.
What is the pattern in the values as the exponents increase?
Answer:
Multiply the previous value by 3.
Step-by-step explanation:
The correct pattern in the values as the exponents increase is - Multiply the previous value by 3.
We can see, that [tex]3^{-1}[/tex] is [tex]\frac{1}{3}[/tex]
And in the next step, [tex]3^0[/tex] is [tex]\frac{1}{3}\times3=1[/tex]
In the next step, [tex]3^1[/tex] is [tex]1\times3=3[/tex]
In the last step, [tex]3^2[/tex] is [tex]3\times3=9[/tex]
So, at each step, 3 is multiplied to the previous product/value.
Therefore, the correct answer is last option.
Answer: D. Multiply the previous value by 3

Answer:
Angle 2
Step-by-step explanation:
Looking at triangles ABD and ACD, they have parts which correspond. These parts are located in the same location in each triangle.
Angle 1 corresponds to Angle 2.
Answer:
The angle ∡1 is equivalent to ∡2
Step-by-step explanation:
We need to start with one reasonable assumption on the image to understand the thought process: "In the rhomboid at the left side, the length of AB is equal to AC".
If we trace a line from B to C, the left side of the rhomboid will be an isosceles triangle (see attached image).
One of the characteristics of these triangles is that if we trace a line directly from the vertex A to the opposite side (line BC) it splits the angle by half, so one half would be ∡1 and the other would be the answer: ∡2

80,000,000 in scientific notation would look like this...
8 x 10^7
It’s as simple as that. Let me know if you need any more help understanding!
Answer: 8×10^7
explanation: when doing scientific notation, you want the number(8) to be less than 10 so you would move the decimal left 7 places so it becomes 8.0000000, and then you would take 8 and put it in the equation so it's 8×10^7

So in interest is given once a year.
Year's interest = 200 × 12%
= 200× 12/100 = $24
2 Years' interest = 24 × 2 = $48
Money paid for loan
= 200 + 48
= $248
Ans = $248
Happy to help. Marking me the brainliest would really be appreciated.
Answer:
The amount you pay to the loaner is $248 but the amount of intrest you paid is $48
Step-by-step explanation:
Your Intrest is 12% so the decimal of that is .12. so Multiply .12 with 200, to find out 12% of 200
200 x .12 =24
so 12% of 200 is 24. But also 24 is the amount of intrest you would pay for 1 year. since you have to pay for TWO years multipy 24 by 2
24 x 2 = 48
so you pay $48 in intrest

the area of a square garden is 1/36 mi 2 how long is each side
Answer:
1/6 meters
Step-by-step explanation:
Let the side length be x.
Then the area of the square = x^2
∴ x^2 = 1/36
√(x^2) = √(1^2 / 6^2)
x = 1/6
Therefore, the side length is 1/6 meters.

What is the value of y?
Answer:
y= 114
Step-by-step explanation:
1) (4x+ 2x- 12+ 20)=180
First find x (22)
2) (2x+20)+y=180
Plug in x
3) y=114
The values of x and y are 16 and 124 respectively when the angles (4x - 12) and (2x + 20) are vertically opposite and one of these angles forms a linear pair with angle y.
Explanation:The subject of this question is mathematics, focusing on geometry and algebra. Vertically opposite angles are equal. Hence, (4x-12) = (2x+20). Solving for x, we get x = 16.
Also, it is mentioned that one of the angles forms a linear pair with angle y. A linear pair means that the two angles add up to 180 degrees. So, y + (2x+20) = 180. Substituting x = 16 in this equation and solving for y, we find that y = 124.

Chloe needs 80 hot dogs for her party. If each hot dog package has 8 hot dogs, how many packages of hot dogs does Chloe need to buy?
Answer:
10 Packages.
Step-by-step explanation:
8 * 10 = 80
Final answer:
To find out how many packages of hot dogs Chloe needs to buy, divide the total number of hot dogs she needs by the number of hot dogs in each package. Chloe needs to buy 10 packages of hot dogs.
Explanation:
To find out how many packages of hot dogs Chloe needs to buy, we need to divide the total number of hot dogs she needs by the number of hot dogs in each package.
80 hot dogs ÷ 8 hot dogs per package = 10 packages
Chloe needs to buy 10 packages of hot dogs.
What is the volume of an cylinder shown below with radius of 11 and height of 12
Answer:
4561.6 units squared
Step-by-step explanation:
The volume of a cylinder is defined by this equation: πr2h
r = radius = 11 units
h = height = 12 units
π = pi = 3.14152...etc. (In your case, just use 3.14)
So you plug these into the equation:
πr2h = (3.14) x (12) x (11^2)
Here, we will write squared as a number ^2, meaning that you multiply that number by itself twice.
Since 11 x 11 = 121, we can now solve for the volume:
(3.14) x (12) x (121) = 4561.6 units^2
