In which number does the digit 3 have a value that is ten times greater than the value of the digit 3 in the number 145,317?
A number where the digit 3 has a value ten times greater than the 3 in 145,317 can be 143,417.
How to work with place values?
In any number, the place value refers to the "place" that a digit has on a number. The first one is the units place, the second is the tens place, and so on.
As more in the left is the place value, the largest value it represents.
Particularly, in 145,317
The 3 is on the third place, so it represents the value 300.
For example, in 143,417
The 3 is more in the left than before, this time on the fourth place, this time the value of the 3 is 3,000.
Then, a number where the digit 3 has a value ten times greater than the 3 in 145,317 can be 143,417.

I need help with this one, it's just subtracting as is. Thank you
Answer:
= .75 gallons or 3 quarts
Step-by-step explanation:
Known
1 gallon = 4 quartsProblem:
4 gallons 2 quarts - 3 gallons 3 quarts
⇒ 2 quarts: 0.5 gallons
⇒ 3 quarts: 0.75 gallons
Add on both sides
4 + 0.5 = 4.5 gallons
3 + 0.75 = 3.75 gallons
This leaves the equation at:
4.5 gallons - 3.75 gallonsThis equals 3 quarts or 0.75 gallons.

graph linear equation 6x - 2y = 12
The graph of the linear equation 6x - 2y = 12 would be option C .
What is a linear equation?Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c
Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.
Subtract both sides from 6x, leaving you with the equation:
-2y = -6x + 12
Now, you divide all of the sides by -2,
y = 3x - 6
The graph of the linear equation 6x - 2y = 12 would be option C .

Answer:
a) -3
b) 9
c) -3
Step-by-step explanation:
a)
[tex]2^5 * 2^{-8} = 2^a[/tex]
In cases where we have a multiplication with exponents we keep the integer as it is and we add the exponents. 5 + -8 = -3. Therefore a is 3.
b)
[tex]\frac{4^7}{4^-{2}} = 4^b[/tex]
In cases when we have a division with exponents we keep the integers as it is and we subtract the exponents. 7 - (-2) = 7 + 2 = 9. Therefore, b is 9
c)
[tex]\frac{7^9}{7^c} = 7^{12}[/tex]
We are dividing again however we are finding the denominator.
9 - (c) = 12
Subtract from both sides: -c = 3, To make c positive we just make the value negative, c = -3. Therefore c is -3
A manager finds a moderate negative correlation between the number of computer sales and the number of microwave sales in his store.
Which statement is true?
The correlation is most likely a coincidence.
The correlation is most likely due to a lurking variable.
The correlation is most likely a causation.
The true statement is the correlation is most likely due to a lurking variable.
What is negative correlation?
Correlation is a statistical measure used to measure the relationship that exists between two variables. Negative correlation is when there is an inverse relationship between the two variables. If one variable increases, the other variable decreases.
Assume that the store is located near a school where the students live on an allowance. So, students do not have time to buy both computers and microwaves. When students buy computers they do not have enough money to buy microwaves. This explains the negative correlation.

A sum of Rs. 12,500 amounts to Rs. 16,500 in 4 years at the rate of simple interest. What is the rate of interest?
Answer:
100
Step-by-step explanation:
Answer:
The rate of interest is6.4 %
Step-by-step explanation:
Given : Principal (P) = Rs12500
Total amount (A) = Rs16500.
The time period (t) =5 years
To find : Rate of interest (R) = ?
Solution :
It is given that Principal (P) = Rs. 12500
Total amount (A) = Rs. 16500
The time period (t) =5 years
We have to find rate of interest (R).
We know the formula for simple interest as,
S.I. = A-P
= 16500±12500
= Rs. 4000
Now, to find rate of interest, use the formula for simple interest as
S.I. =
∴
∴ *R
∴
∴
∴R=6.4 %
∴ The rate of interest is6.4 %.

Suppose you have entered 97-mile biathlon that consists of a run and a bicycle race. During your run, your average velocity is 8 miles per hour, and during your bicycle race, your average velocity is 27 miles per hour. You finish the race in 5 hours. What is the distance of the run? What is the distance of the bicycle race?
The distance of the run Will be 16miles and the Distance of the bicycle race will be 81 miles.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Distance = average velocity × time
Let the time and distance of the run, respectively, be t₁ and.d₁
Let those of the bicycle race be t₂ and d₂
From the question,
t₁ + t₂ = 5
d₁ = 8t₁
d₂ = 27t₂
Total distance = 97
8t₁ + 27t₂ = 97
8 ( 5 - t₂ ) + 27t₂ = 97
40 - 8t₂ + 27t₂ = 97
40 + 19 t₂ = 97
19t₂ = 57
t₂ = 3 hours
t₁ + t ₂ = 5
t₁ = 5 - t₂
t₁ = 5 - 3 = 2 hours
Now the distances are calculated as:-
d₁ = 8t₁ = 8 x 2 = 16 miles
d₂ = 27t₂ = 27 x 3 = 81 miles
Therefore the distance of the run Will be 16miles and the Distance of the bicycle race will be 81 miles.

If a prism is placed into a basin of water (density: 32.5 lbs/ft^3 ) displaces 3.3 lbs of water, what is the volume of the water that was displaced (in cubic inches)?
Please help
The volume of water that was displaced is 0. 000019 cubic meters.
What is volume?Volume is known to be the amount of space or capacity occupied by a three-dimensional solid shape.
It is denoted in cubic units.
How to calculate the volumeThe formula for calculating volume is;
Volume = mass ÷ density
Given that mass = 3. 3 Ibs and density = 32. 5Ibs/ ft∧3
Volume = 3. 3 ÷ 32. 5 = 0. 10 Ibs
How to covert Ibs to cubic meters
Ibs = 0. 00019 m∧3 (cubic meters)
Then, 0. 10 Ibs = 0. 00019 × 0.10 ÷ 1 = 0. 000019 cubic meters.
Therefore, the volume of the water displaced is 0.000019 cubic meters.

Answer:
To pull our the first chocolate, it would be a probability of 1/2.
To pull the second chocolate out, it would be a probability of 2/5.
Hope that helps, you just use ratios, the first cupcake needs to be chocolate, and there are 3 chocolate cupcakes out of the 6. Make that into a fraction 3/6, and simplify into 1/2.
