In which number does the digit 9 have a value that is 1/10 of the value of the digit in 8.097
Answers
STEP BY STEP EXPLANATION:
If this question asks you what is a fraction of a number that means you divide that number. In this instance you divide this number by 10, because you are trying to find the value of this number at 1/10. Once that number is divided by 10 setting every number in that value back one that means that the 9 would move back one space. So instead of making it’s value 9 hundredths, it is now 9 thousandths. (Even smaller)

Jackson is creating a rectangular board game that includes a diagonal line from two of the corners of the game. How long is the diagonal if the board game is 10 inches
long by 8 inches wide? Explain your reasoning. Round your answer to the nearest tenth of an inch.
Helppp
Answers
Answer:
diagonal = = 12.8 inches (to the nearest tenth of an inch)
Step-by-step explanation:
As shown in the diagram attached to this solution:
Let the Length of the rectangular board = a
Let the width = b
Let the diagonal = d
where:
a = 10 inches
b = 8 inches
d = ?
Triangle ABC in the diagram is a right-angled triangle, therefore, applying Pythagoras theorem:
(hypotenuse)² = (Adjacent)² + (Opposite)²
d² = 10² + 8²
d² = 100 + 64
d² = 164
∴ d = √(164)
d = 12.806 inches
d = 12.8 inches (to the nearest tenth of an inch)
N:B Rounding off to the nearest tenth of an inch is the same as rounding off to 1 decimal place.

Answers
Answer:
10 5/8
Step-by-step explanation:
9 3/4 + 7/8 = 9 6/8+7/8=
10 5/8
The distance jumped by Chris in total would be as follows:
[tex]10\frac{5}{8}[/tex]
Find the distance
Distance is denoted as the space that one covers from a particular place to the other.
Given that,
The distance jumped by Mark [tex]= 9\frac{3}{4}[/tex] feet
The distance jumped by Chris [tex]= \frac{7}{8} + 9\frac{3}{4}[/tex]
So,
The total distance covered by Chris would be:
[tex]= \frac{7}{8} + 9\frac{3}{4}[/tex]
[tex]= \frac{7}{8} + \frac{39}{4}[/tex]
[tex]=[/tex] [tex]\frac{(7 + 78)}{8}[/tex]
[tex]= \frac{85}{8}[/tex]
[tex]=[/tex] [tex]10\frac{5}{8}[/tex]
Thus, [tex]10\frac{5}{8}[/tex] is the correct answer.

Chris invests $18,000 into an account at an annual rate of 0.4% simple interest for 12 months. 5) Calculate the simple interest earned on this account.
Answers
Answer:do you have a screenshot
I is the interest, P is the principal, or deposited amount, R is the rate as a decimal, not percentage, and T is time in years.
Convert 0.4% to a decimal by dividing by 100 = 0.004
Convert 12 months into years = 1
I = (18,000)(0.004)(1)
I = 72
$72 interest earned.

A village water tank contained some water. The villagers used 10300 litre of the water in the day. A pump supplied 12,700 of the water in the tank. There was 16500 litre of water left in the tank in the end. How much water was there in the tank at first?
Answers
Answer:
13830
Step-by-step explanation:
the amount of water that was left is 16500, so substract it to the added amount of water which is 12700, then add 10300 which is the amount of water that the village consumed. 16500-12700=3800+10300=13830

Mr. Spencer wants to rent a car.He has two deals:
Deal A: rent Tesla with initial fee of$75 and
$25 fee each day
Deal B: rent Porsche with no initial fee and $50 each day
Help Mr.Spencer to select a better deal.
Answers
Answer:
The answer is depending on how long he us going to rent the car. If Spencer wants to rent the car for less than 150 days, the Porsche is cheaper for that. However, if Spencer wants to rent a car for more than 150 days, the Tesla is the cheaper option.
Step-by-step explanation:
You can write both Deals in slope inter form.
Tesla: y = 25x+75
Porsche: y=50x
Remember: slope inter form is y = mb + b
"mx" being the change in y over the change in 1 or (y1-y2/x1-x2)
"b" in the formula represents the y-axis
