If a player always gets three cards, describe two different ways to recieve a score of 7.
Answer:
1 + 3 + 3 = 7
5 + 1 + 1 = 7
Step-by-step explanation:
If a player have the three cards. Each card will have a number and we have to find the numbers on each card that total 7.
Let card 1 gets 1
Then other two cards may have 3 and 3
So, 1 + 3 + 3 = 7
Now we take another combination which totals 7
5 + 1 + 1 = 7
Therefore, there may be two different ways are
1 + 3 + 3 = 7
5 + 1 + 1 = 7

Initially a pool contains 250 gallons of water. A hose is placed in the pool, and the water is turned on. The hose adds 5.4 gallons of water per minute. Write a linear model that represents the amount of water, V, in the pool as a function of time, t, in minutes.
Answer:
The amount of water in pool after t minutes V = 250 + 5.4 t
Step-by-step explanation:
Amount of water in pool = 250 gallons.
The hose adds 5.4 gallons of water per minute.
Rate at which hose is adding water = 5.4 gallons per minute
We need to write a linear model that represents the amount of water, V, in the pool as a function of time, t, in minutes
We have
V = 250 + 5.4 t
The amount of water in pool after t minutes V = 250 + 5.4 t
Use a bar model to find the unknown value: 3/6 = ?/7
The solution to the problem 3/6 = ?/7 when using a bar model to visualize it, is 3.5. This can be calculated by understanding equivalency between fractions.
Explanation:To solve this problem using a bar model, imagine dividing a bar into 6 equal parts (representing the denominator of the fraction on the left). If 3 of those parts (representing the fraction’s numerator) equals 3/6 or 0.5. Now, we want to know how many sevenths would be equivalent to that same amount. Since 1/2 is equivalent to 3.5/7, the answer to the question 3/6 = ?/7 would be 3.5.

Your office manager has given you a budget of $30,000 to replace the old computers in your office with new ones. Each new computer will cost $550. You make a quick count and determine that 15 computers will need to be replaced. How much money will be left (per week) for the next six weeks?
1) 550 x 15 = 8250 (First you want to get the total cost of the computers)
2) 30,000 - 8250 = 21,750 (Then you want to subtract that by 30,000 to see how much money is left over)
3) 21,750/6 = 3625 (Then divide by 6 ,by the weeks, and get your answer)

Danielle has a CD at crossland bank. she invest $22,350 for four years at 4.55% interest. compounded monthly. What is her ending balance? How much interest did she make?
Answer: Her ending balance is $26,703.837 and her interest is $4,353.837
Step-by-step explanation:
First year,
p =22350 R = 4.55 T = 1
Interest = PRT/100
= 22350 × 4.55 × 1 / 100
=$1016.925
P = $22350 + $1016.925 = $23366.925
For the 2nd year,
I = $23366.925 × 4.55 × 1 / 100
=$1063.195
p= $23366.925 + $1063.195 = $24,430.12
For the 3rd year,
I = $24,430.12 × 4.55 × 1 / 100
= $1111.57
p = $24,430.12 + $1111.57 = $25,541.68
For the 4th year;
I = $25541.68 × 4.55 × 1 / 100
= $1,162.147
P = $ 25541.69 + $1,162.147 = $26,703.837
Therefore th ending balance is $26,703.837
Her compound interest is , $26,703.837 - $22350 =$4,353.837
What is the equation in point slope form of the line that passes through the point (2,6) and has slope of 5?
A: y+2=5(x+6)
B: y-6=5(x-2)
The equation of the line that passes through the point (2,6) and has slope of 5 is Option B:
y - 6 = 5 ( x - 2 )
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
Given data ,
Let the point be P( x₁ , y₁ ) = P( 2 , 6 )
Slope m = 5
Now , the equation of line is given by the equation
y - y₁ = m ( x - x₁ )
Substituting the values of x₁ , y₁ and m in the equation , we get
y - 6 = 5 ( x - 2 )
Therefore , the equation of the line is y - 6 = 5 ( x -2 )
Hence , equation of the line that passes through the point (2,6) and has slope of 5 is y - 6 = 5 ( x - 2 )

Which expression is equivalent to −2.6+(−2.9)+(−7.1) ?
Answer:
-12.6
Step-by-step explanation:
To evaluate the given expression
-2.6+(−2.9)+(−7.1, first we will open out the brackets and multiply the signs. Before that, we must take note of the following sign operations
-×- = +
-×+ = -
+×- = -
+×+ = +
The equation above becomes;
-2.6-2.9-7.1 (all the signs are now minus since the product of plus and minus sign gives a minus sign)
(-2.6-2.9)-7.1
= -5.5-7.1
= -12.6
Since all the values in the equation are negative values, our resulting answer will be a negative value.

8439 divided by 245 with remainder
Answer:
The remainder of 8439 divided by 245 is 109.
Step-by-step explanation:
Given two numbers as 8439 and we have to divide it by 245.
That is , Dividend = 8439
Divisor = 245
Solution:
Using division algorithm,
Dividend = ( Divisor * Quotient )+Remainder
8439 = (245*34)+Remainder
8439 =8330+Remainder
Taking 8330 to other side to find the remainder, we have
8439 -8330 = Remainder
109 = Remainder
Thus The remainder of 8439÷245 is 109.

In a recent year, the population of California was about 2.52 x 10^7 people. Its land area is about 4.05 x 10^5 km^2. What was the average number of people per square kilometer? Write your answer in scientific notation.
PLEASE I NEED HELP ASAP!!!!!!!!!!!!
The average number of people per square kilometer in California is [tex]6.22 \times 10^1.[/tex]
To find the average number of people per square kilometer in California, we divide the total population by the land area.
Given:
Population of California = [tex]2.52 \times 10^7[/tex] people
Land area of California = [tex]4.05 \times 10^5 km^2[/tex]
Calculate the population density.
Population density = Population / Land area
Population density = [tex](2.52 \times 10^7) / (4.05 \times 10^5) people/km^2[/tex]
Divide the numbers and simplify.
Population density = (2.52 / 4.05) x 10^(7-5) people/km^2
Population density = [tex]0.622 \times 10^2 people/km^2[/tex]
Rewrite in scientific notation.
Population density = [tex]6.22 \times 10^1 people/km^2[/tex]
So, the average number of people per square kilometer in California is [tex]6.22 \times 10^1[/tex].
