Answer:
120in
Step-by-step explanation:
Okay, this is going to be a long one so hang onto your hats let's go
So, we first have to find the length that each of the frogs jumped so:
We're going to start with froggy #1, the 2-inch frog:
2 x 20 = 40
So froggy #1 can jump up to 40 inches so we're going to assume that each time our froggies jump, they jump to their full extent:
40 x 3 = 120
So froggy #1 jumped 120 inches
Now, we do the same with froggy #2, the 4-inch frog:
4 x 20 = 80
80 x 3 = 240
So froggy #2 jumped 240 inches
Now, we have to figure out how far ahead froggy #2 is from froggy #1:
240 - 120 = 120
So, the two froggies will end up 120 inches apart

Someone please help me I’ll give out brainliest please dont answer if you don’t know
Answer:
Step-by-step explanation:
Ok, so remember your order of operations here.
Also, Remember that what we do to one side, we must do to the other side.
We cant solve whats in the parentheses, so that wont come first. The next best thing is the multipication of 0.8 in front of it:
0.8x(2x-4)
=
1.6x-3.2
Now lets rewrite the equation as:
1.6x-3.2=16
Now lets simply solve the rest:
1.6x=19.2
All I did is add 3.2 to both sides so I could get 1.6x on its own.
What is left is just dividing 1.6x to get 1x:
1.6x/1.6=19.2/1.6
This gets us:
x=12
This is because we divided 1.6 from both sides so that 1.6x became just x.
Answer:
12

x-5+2x-7 find the vale pleaser!!
Answer:
12
Step-by-step explanation:
They are the same angle so they must be equal.
So, x+5 = 2x-7
5+7 = 2x-x
12 = x

2. The number of atoms of a particular chemical element is modelled by
the following function: y=600 x 3-* where x is the number of hours.
a) How many atoms of the element were there at the start?
b) Draw a graph for 0
c) At what time were there 150 atoms?
9514 1404 393
Answer:
a) 600
b) see below
c) 1.26 hours
Step-by-step explanation:
a) The value of y when x=0 is the coefficient of the exponential term:
y = 600·3^(-0) = 600·1 = 600
There were 600 atoms to start.
__
b) see attached for a graph
__
c) The graph shows 150 atoms at t = 1.26, about 1.26 hours after the start of time counting.
If you want to find that value algebraically, substitute for y and solve for x. Logarithms are involved.
150 = 600·3^(-x)
150/600 = 3^(-x)
log(1/4) = -x·log(3)
x = -log(1/4)/log(3) = log(4)/log(3) ≈ 1.2618595
After about 1.26 hours, there were 150 atoms.

In an election the successful candidate registered 5,77,500 votes and his nearest rival secured 3,48,700 votes by what margin did the successful candidate win the election.
Answer:
the successful candidate won the election with a 24% margin.
Step-by-step explanation:
With the infomation provided, first you need to find the total amount of votes by adding the number of votes that the successful candidate registered plus the number of votes that his nearest rival secured:
577,500+ 348,700=926,200
Next, you need to find the percentage of votes that the successful candidate registered and that the nearest rival secured by dividing the number of votes by the total amount of votes and multiplying the result for 100:
577,500/925,200=0.62*100=62%
348,700/926,200=38%
Now, you need to find the difference between both percentages to get the margin:
62%-38%=24%
According to this, the answer is that the successful candidate won the election with a 24% margin.
Angus Cut His Neighbors' Lawns For The Summer. By The End, He Had $325 In His Lawn-cutting Bank Account And He Paid A Total $75 For Gas. He Earned $10 For Ever Lawn He Mowed. How Many Lawns Did He Buy? A. N = 400 x 10 b n 250 x 10 c. N = 400 / 10 d. N = 250 / 10
Answer:
C. N = 400 / 10
Step-by-step explanation:
Lawn-cutting Bank Account = $325
Amount paid for gas = $75
Total amount earned = Lawn-cutting Bank Account + Amount paid for gas
= $325 + $75
= $400
Amount earned per every lawn he mowed = $10
How Many Lawns Did He mow?
Let N = number of lawns he mowed
N = Total amount earned / Amount earned per every lawn he mowed
N = 400 / 10
N = 40 lawns

List three values for x that would make 5x < -20 true.
Answer:
1. -5
2. -6
3. -10
Step-by-step explanation:
There are x = - 6, -7, and - 8 three values for variable x that would make 5x < -20 true.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We have been given that the inequality is below as
⇒ 5x < -20 ...(i)
⇒ 5x / 5 < -20 / 5
⇒ x < - 4
Thus, all the negative values which are less than -4 for x would make it true.
For example, we take x = -8
Substitute the value of x = -8 in the inequality (i),
⇒ 5(-8) < -20
⇒ - 40 < -20
This is true.
Similarly x = - 6, and - 7 also for x would make it true.
Hence, there are x = - 6, -7, and - 8 three values for variable x that would make 5x < -20 true.

Vinay bought a pizza and cut it into three pieces. When
he weighed the first piece he found that it was 7g lighter
than the second piece and 4g.heavier than the third piece.
If the whole pizza weighed 300g. How much did each of
the three pieces weigh?
(Hint: weight of first piece be 'x' then weight of second
piece is 'x + 7', weight of the third piece is 'x - 4')
Answer:
x + x + 7 + x -4 = 300
3x = 297
x = 99 First Piece
x2 = 106 Second Piece
x3 = 95 Third piece

In ⊙Q, mJK=180° and mLM=116°. What is m∠1?
Answer:
64degrees
Step-by-step explanation:
From the given diagram;
m<LK = 180degrees
m<LM = 116degrees
Required
m<1
Since <1 and <LM lies on the same straight line, hence;
m<1 + m<LM = 180
m<1 + 116 = 180
m<1 = 180 - 116
m<1 = 64degrees
Hence the measure of m<1 is 64degrees
Answer: 32
Step-by-step explanation:
2a+180+116=360
2a=64
a=32

If the area of a rectangle in terms of x is x2 + 15x + 26 / 6x2 and its width is x2 - 3x - 10 / 30x3 Find the length of the rectangle.
Answer:
The length of the rectangle is;
5x(x+13)/(x-5)
Step-by-step explanation:
Mathematically, we know that the area of a rectangle is the product of the length and width of the triangle
To find the length of the rectangle, we will have to divide the area by the width
we have this as;
(x^2 + 15x + 26)/6x^2 divided by (x^2-3x-10)/30x^3
thus, we have ;
(x^2 + 15x + 26)/6x^2 * 30x^3/(x^2-3x-10)
= (x^2+15x+ 26)/(x^2-3x-10) * 5x
But;
(x^2 + 15x + 26) = (x+ 2)(x+ 13)
(x^2-3x-10) = (x+2)(x-5)
Substituting the linear products in place of the trinomials, we have;
(x+2)(x+13)/(x+2)(x-5) * 5x
= 5x(x+13)/(x-5)

Find the volume of a figure that has a length of 5 cubic units, a width of 5 cubic units, and a height of 5 cubic units. *
Answer:
V = 125 cubic units
Step-by-step explanation:
The formula for volume is length x width x height. Now we must solve.
Solve:
5 x 5 x 5 = 125
125 cubic units
Answer:
125 units^3
Step-by-step explanation:
To find the volume of a cube (a figure with all the same side lengths) you multiply any length by itself 2 times or cube it
5^3 = 5*5*5 = 125 units^3
Those are the reasons when I put BD perpendicular to AC
Step-by-step explanation:
