The age of earth’s crust is 5 · 10^9 years. Express this number as an integer.
Answer:
5,000,000,000 (see below)
Step-by-step explanation:
Integers are whole numbers and their opposites. That doesn't include fractions or decimals, even if they're negative. Being negative doesn't do anything, really.
For example, 5 and –5 are integers, but 5.1 or –5.3 are not integers. They're decimals, which means they're rational.
Integers also include 0.
Whole numbers do not include 0, so they're only 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . and so on.
All whole numbers are integers.
So in order to find 5 × [tex]10^{9}[/tex] as an integer, you'll have to multiply the 5 and [tex]10^{9}[/tex] together.
[tex]10^{9}[/tex] is simply nine zeros, so it's: 1,000,000,000.
5 × 1,000,000,000 = 5,000,000,000
5,000,000,000 is not a decimal or fraction—and it also isn't negative. That means it's a whole number. Which qualifies it as an integer as well.

5(2d+2) = 3 (8d-5)
Answer:
d = 25/14
Step-by-step explanation:
5(2d+2) = 3 (8d-5)
10d + 10 = 24d - 15 | +15
10d + 25 = 24d | - 10d
25 = 14 d | :14
d = 25/14

contains 40 gallons of water is having 2 gallons added per hour. After how many hours will the first tank
have less water than the second? Which inequality represents the situation?
a. 100+ h > 40 - 2h
c. 40-h > 100 + 5h
b. 100-h< 40 + 2h
d. 100-h > 40 + 2h

Answer:
B
Step-by-step explanation:
the first fish tank has 100 gallons of water and 1 gallon is removed every hour which makes 100-h
the second tank has 40 gallons in it and 2 gallons are added every hour which makes 40+2h
after 20 hours the second tank will have more gallons than the first tank
this means that 40+2h would be greater than 100-h since it's also asking you "After how many hours will the first tank have less water than the second?"

Find values of a and b that make both equalities true: a/b = 2/5 and 22/a = 11/6 .
Answer:
a=32b=80Step-by-step explanation:
Find values of a and b that make both equalities true:
a/b = 2/5 and 22/a = 11/6 .
given that 22/a=11/16
cross multiply
11a=22x16
11a=352
a=352/11
a=32
put a=32 in a/b = 2/5 to find b we have
32/b=2/5
cross multiply we have
2b=32x5
2b=160
divide both sides by 2 we have
b=160/2
b=80
Answer:
Step-by-step explanation:
First, we will start by solving: 22/a = 11/6
Solving for a
We can first cross multiply and we get this: 22 x 6 = 11a, Simplified it would be 132 = 11a. Now we know that a = 12.
Solving for b
Now knowing a = 12 we can get this. 12/b = 2/5 same thing, cross multiply. That would be: 12 x 5 = b x 2, Simplified: 60 = 2b so b = 30

Which expression is equivalent to 32 ⋅ 3−5?
Answer:
91
Step-by-step explanation:
Using the PEMDAS method (parentheses exponenets multiplication division addition subtraction), we know that since 3-5 is not in parentheses, we have to multiply before we subtract. So first, we must multiply 32 x 3 to get a product of 96. Then we must subtract, 96 - 5 = 91. Therefore, your answer is 91.
Hope this helped! Good luck!

A rectangle is dilated using a scale factor of 6. The
image is then dilated using a scale factor of 1/3. What
scale factor could you use to dilate the origianl
rectangle to get the final rectangle? Explain.
9514 1404 393
Answer:
2
Step-by-step explanation:
The second rectangle's dimensions are 1/3 of those after they were multiplied by 6, so are (6)(1/3) = 2 times the original dimensions.
A scale factor of 2 could be used to get the final rectangle.
Prove the polynomial identity. (2x−1)2+2(2x−1)=(2x+1)(2x−1) Drag and drop the expressions to correctly complete the proof of the polynomial identity. (2x−1)2+2(2x−1)=(2x+1)(2x−1) Response area+4x−2=(2x+1)(2x−1) Response area=(2x+1)(2x−1) Response area=(2x+1)(2x−1)
Answer:
Step-by-step explanation:
Given expression is,
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
To prove this identity we will take the left hand side of the equation and will prove equal to the right side.
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
4x² - 4x + 1 + 4x - 2 = (2x - 1)(2x + 1)
4x² - 1 = (2x - 1)(2x + 1)
(2x - 1)(2x + 1) = (2x - 1)(2x + 1) [Since a² - b² = (a - b)(a + b)]

If there are 9 rows of seats with 18 seats in each row there are also 6 rows of seats with 24 seats in each row how many seats are there in the auditorium
Answer:
306
Step-by-step explanation:
The number of rows times the number of seats in each row is equal to the stadium chair. Using this, 9 rows of seats with 18 seats in each row is 9(18) and 6 rows with 24 seats in each row is 6(24). Now we add 9(18) + 6(24), which is 162 + 144 which is 306 seats
George is 2 in. taller than the quotient of Myron's height and 3. Let M represent Myron's height, in inches. Write an expression that represents George's height, in inches.
Answer:
G = M/3 + 2
Step-by-step explanaion
We can interpret the quotient of Myrons height and 3 as "M/3" and we add "+2" to account for the "2 in. taller" part of the problem. We can also represent George's height using "G"
The expression that represents George's height, in inches is G = M/3 + 2
What is algebra?
Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.
Given:
George is 2 in. taller than the quotient of Myron's height and 3.
let M represent Myron's height, in inches.
and, the quotient of Myrons height and 3 can be written as
=M/3
Now, add 2 to Myron's height.
