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
The corresponding sides of ΔABC and ΔDEF have equal lengths. The area of ΔABC is 4 square units, and the longest side of ΔDEF is 5 units long. What is the area of ΔDEF? PLEASE HELP!!
Answer:
The area of ΔDEF will be [tex]4[/tex] square units.
Step-by-step explanation:
The area of [tex]\triangle ABC[/tex] is [tex]4[/tex] square units.
The corresponding side lengths of [tex]\triangle ABC[/tex] and [tex]\triangle[/tex]DEF are equal.
That means, two triangles are congruent according to [tex]SSS[/tex] postulate.
So, their area will be also equal.
Thus, the area of ΔDEF will be [tex]4[/tex] square units.
The figure shows two intersecting lines and the measures of the resulting angles.
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.

Which of these numbers are irrational?
I just need to know if im right or not Lol
Answer: The answer is A
I need help please. 2nd box: meters, cubic meters, or square meters.
Answer:
I believe it is meters
Step-by-step explanation:
I think so because the rectangle is labeled with meters
To find out area of a rectangle it is (l*w)
In this case it is 9m*7m which is 63 metres squared
Area is 63 metres squared
To find out perimeter of a rectangle we do 2(l*w)
In this case it is (2*9)+(2*7) which is 9+9+7+7=18+14 which is 32
Perimeter is 32 metres
H/6-1=-3 solve for H
Add 1 to both sides
h/6 = -3 + 1
Simplify -3 + 1 to -2
h/6 = -2
Multiply both sides by 6
h = -2 * 6
Simplify 2 * 6 to 12
h = -12

Will mark brainliest!!!!!!!! Show work!!!14
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

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.

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.

Sandy mixed 9 ml of an acidic solution with 8 ml of a 42% acidic solution, to make a 45% acidic solution. Find the percent acid concentration of the first solution.
Answer:
47.67%
Step-by-step explanation:
Amount of 1st solution = 9 ml
Let the percentage acid concentration of 1st solution is x%
Amount of 2nd solution = 8 ml
Percentage acid concentration of 2nd solution = 42%
Percentage acid concentration of the mixture = 45%
Amount of the mixture = 8 + 9 = 17 ml
1st Solution + 2nd Solution = Mixture
x% of 9 ml + 42% of 8 ml = 45% of 17 ml
[tex]0.09x + 3.36 = 7.65\\\\ 0.09x = 7.65 - 3.36\\\\ 0.09x = 4.29\\\\ x = \frac{4.29}{0.09}\\\\ x = 47.67[/tex]
Thus, the percent acid concentration of first solution is 47.67%

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
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

Mrs. Jackson is covering her bulletin board with new paper. What formula should she use to figure out how much paper to buy?
Answer: A = L x W
Step-by-step explanation:. Mrs. Jackson should use the formula to calculate area in order to figure out how much paper to buy. The formula is Area = Length x Width. This will tell her exactly how much paper she will need to cover the bulletin board.
Answer:
Step-by-step explanation:
Something of this size could be measured in either ft² or in².
Area of a rectangle is determined by multiplying the width by the height. In this case the bulletin board will be installed vertically, so let's say that
Area of board = (width)(height)
If, for example, the width were 6 feet and the height 3.5 feet, the area of this board would be (6 ft)(3.5 ft) = 21 ft²
Since 1 ft = 12 in, this 6 foot by 3.5 foot board would be 72 inches by 42 inches.
