Divide the following numbers in scientific notation?
Answer:
b
Step-by-step explanation:
because i need trust in my life
Answer:
D) 2.6875 × 10^5
Step-by-step explanation:
Convert to Scientific Notation
8.6 × 10^8
₋₋₋₋₋₋₋₋₋₋₋₋
3.2 × 10^3
Convert the fraction to a decimal by dividing the numerator by the denominator.
268750
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the e xponent will be positive.
2.6875 × 10^5
3. A rectangle has an area of

square feet. If its width is 3 1/4 feet, then find its length.
Express it in mixed number form.
Simplify
7 1/5 times 49 7/5 equivalent to 49
Step-by-step explanation:
7 1/5 × 49 7/5 = 49
convert mixed numbers into improper fractions (whole number × denominator + numerator)
7 × 5 + 1 = 36
49 × 5 + 7 = 252
36/5 × 252/5 = 49
All fractions must have a common denominator
49 × 5 = 245
36/5 × 252/5 = 245/5
Add numerators
36 + 252 = 288
288/5 = 245/5
57 3/5 = 49
These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?
Aisha had 2 gallons of paint. She used 4 /5 of the first gallon and 1/4 of the second gallon.
How many gallons were left over?
A: 15 gallon
B: 34 gallon
C: 1920 gallon
D: 1120 gallons
Answer:
19/20
Step-by-step explanation:
you spelled them wrong A is 1/5 B is 3/4 C is 19/20 D is 11/20 but C is the right answer
The leftover gallon of paint she has now is C: 19/20 gallon
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Aisha had 2 gallons of paint.
She used 4 /5 of the first gallon and 1/4 of the second gallon.
∴ The amount of leftover paint is 2 - (4/5 + 1/4).
= 2 - (16 + 5)/20.
= 2 - 21/20.
= (40 - 21)/20.
= 19/20.

You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is 1 ft:1.26 cm.
Answer:
The model will be 6 toothpicks tall.
Step-by-step explanation:
your school is 30 feet tall and 1 feet is 1.26 cm, so you would most likely multiply 30 and 1.26 in order to get the height of the scale model which is 37.8 cm. Each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks So, for you to build the school, it would be 6 tp tall.

Round 2.500 g to the nearest whole gram
Answer:
Step-by-step explanation:
3 grams.
Answer:
3 grams
Step-by-step explanation:
Whole numbers do not include any decimals. They include numbers such as 1, 2, 3, 4, 5...
2.500 g is equal to 2 and a half grams, which we know is between 2 and 3 grams. This means that the nearest whole gram has to be 2 or 3.
When rounding, look at the digit to the right of the digit being rounded, and if it is 5 or more, round up. If it is 4 or less keep the digit same.
Here, 5 is the digit to the right of 2, so we round up to 3 grams.

Jackson wants to buy a new car and needs a car loan. The cost of the car is $28,326. The car loan interest rate is 0.9% per year
How much money will Jackson pay in interest for one month?
А
$21.24
B
$212.45
С
$254.93
D
$2,124.45
Given :
Jackson wants to buy a new car and needs a car loan.
The cost of the car is $28,326. The car loan interest rate is 0.9% per year.
To Find :
How much money will Jackson pay in interest for one month.
Solution :
Interest on the loan is given by :
[tex]I=28326\times 0.009\\\\I=\$254.934[/tex]
Amount Jackson will pay in interest for each month is :
[tex]A = \dfrac{254.934}{12}\\\\A = \$21.24[/tex]
Therefore, Jackson will pay $21.24 dollar interest per month.
Hence, this is the required solution.
