Answer:
6 * 10^2
Step-by-step explanation:
Simplify : (4.2×10^7)÷(7×10^4)
(4.2 × 10^7) / (7 × 10^4)
From indices : 10^a ÷ 10^b = 10^(a - b)
(4.2 / 7) * 10^(7-4)
0.6 * 10^3
= 6 * 10^2
Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2
Luis has an account at GESA Credit Union. He had a balance of $500.00 starting January 15th. He made deposits of $100, $250, and $300. He also made withdrawals of $400.32, $100, $55.55, and $62.62. What would be his ending balance after all the transactions?
SHOW THE WORK PLEASE
Answer:
the ending balance is $531.51
Step-by-step explanation:
The computation of the ending balance is shown below:
= Opening balance + all deposits - all withdrawls
= $500 + $100 + $250 + $300 - $400.32 - $100 - $55.55 - $62.62
= $531.51
hence, the ending balance is $531.51

Equation:
Volue of x:
Answer:
equation: 36000 + 4000x = 51000 + 1500x
value of x: 6
Step-by-step explanation:
Marshall:
36000 + 4000x
Jim:
51000 + 1500x
36000 + 4000x = 51000 + 1500x
360 + 40x = 510 + 15x
25x = 150
x = 6
Answer:
equation: 36000 + 4000x = 51000 + 1500x
value of x: 6

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?
A quick lesson on probability:
The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity of flipping a coin and getting heads is:
(1 way to get heads) / (2 possible outcomes) = 1/2
Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.
On to the problem.
There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.
Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.
Using the formula to find the probability, substitute the values we just found.
(the number of ways what you want can happen) / (total number of outcomes possible) =
(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.
Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black
7/20 * 100 = 35 times, or D

From her home, Glera traveled 5.8 miles north to the grocery stare, then 2.1 mlles west to the library. What is the distance thom her home to the library
Answer:
6.16 miles
Step-by-step explanation:
When solving word problems like these, I like to start by drawing a picture.
So, Glera starts at her home and moves north by 5.8 miles. Then, she walks west by 2.1 miles to the library. The problem wants you to find the distance from her home to the library.
I've attached a drawing I made to help me visualize the problem. The distance from her home to the library is the hypotenuse of the triangle. To solve for it, you would use the equation [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex].
a and b are the sides of the triangle, and c is the hypotenuse.
[tex]5.8^{2}[/tex] + [tex]2.1^{2}[/tex] = [tex]c^{2}[/tex]
33.64 + 4.41 = [tex]c^{2}[/tex]
38.05 = [tex]c^{2}[/tex]
To find c, you would take the square root of 38.05, which is about 6.16 if you use a calculator.
So, the distance from her home to the library is 6.16 miles!
find the slope between (5,0) and (6,0)
Answer:
The slope is 0
Step-by-step explanation:
There is no change in y values making the slope have a value of 0
Answer:
m = 0
Step-by-step explanation:
(5,0) and (6,0) would form a horizontal line.
All horizontal lines have a slope of zero.
Therefore, the slope of the line between (5,0) and (6,0) is 0.

A 92-inch is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is nothing inches long.
Answer:
23 inches
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
A 92-inch is cut into two pieces.
x + y = 92
One piece is three times the length of the other.
x = 3y
Find the length of the shorter piece.
Hence:
x + y = 92
x = 3y
3y + y = 92
4y = 92
y = 92/4
y = 23 inches
Solving for x
x + y = 92
x + 23 = 92
x = 92 - 23
x = 69 inches
The shorter piece is 23 inches long.

Andrew McCutchen hit 18 homeruns in 9 baseball games. At this rate, how many homeruns will he have hit
in 11 baseball games?
Please show how to do it
Answer:
if it's 18 home runs in 9 baseball games
then you're dividing 18 by 9 which is 2 home runs for every 9 baseball games
to prove if you're right (9×2=18)
if it's 11 baseball games then 11×2=22

Andrew McCutchen hit 18 a number of homeruns in 9 baseball games. . which is determined by the given proportion.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Given that he hit 18 homeruns in 9 baseball games.
Let the number of homeruns would be x will he have hit in 11 baseball games.
According to the given question, we can write a proportion as
18 homeruns : 9 baseball games = x homeruns : 11 baseball games.
18 / 9 = x / 11
Apply the cross-multiplication operation,
18 × 11 = 9x
9x = 198
x = 198 / 11
Apply the division operation,
x = 18
Therefore, he hit 18 a number of homeruns in 9 baseball games.

Akoshia has more money than Komley. If Akoshia gave Komley 20, they would have the same amount. While if Komley gave Akoshia ¢22, Akoshia would then have twice as much as Komley. How much does each one actually have?
Answer:
Aksohia has $146 and Komley has $106
Step-by-step explanation:
The computation of the amount does each one have is shown below:
Let us assume Akoshia money be x
And, komley money be y
x>y
x - 20 = y + 20
x - y = 40
x = 40 + y.........(i)
2(y - 22) = x + 22
2y - 44 = x + 22
Now put the value of x in the above equation
2y - 44 = 40 + y + 22
2y - 44 = 62 + y
y = 62 + 44
= 106
And, x = 40 + 106
= 146
