Each die has six numbers, the total number of possible combinations is 6 * 6 = 36
The combinations in which you can get a sum of 5 are: 1 &4, 2 & 3, 4 &1, 3 &2
There are 4 different combinations of getting a sum of 5.
The probability would be 4/36, which reduces to 1/9
Interesting Question
What you are being asked is What is the line Perpendicular to AB going through point (7,6)
Step One
What is the slope of the given line
-7x + 3y = -21.5 Add 7x to both sides.
3y = 7x - 21.5 Divide by 3
y = 7x/3 - 21.5/3
The slope of the given line is 7/3 (just read it)
Step Two
What is the slope of the line perpendicular to it.
The slopes are connect by the formula
m1 * m2 = - 1
m1 = 7/3
7/3 * m2 = - 1 Multiply by 3/7
m2 = - 1 * 3/7
m2 = - 3/7
Step three
Find the y intercept, where b in the equation below is the y intercept..
y = -3/7 x + b
y = 6
x = 7
6 = -3/7 * 7 + b
6 = -3 + b Add 3 to both sides.
6 + 3 = b
b = 9
Step Three
State the equation
y = - 3/7 x + 9
Now you have to juggle the numbers to get the answer.
Step 4
put the -3/7 x on the left side.
y + 3/7 x = 9 Multiply both sides by 7
7y + 3x = 63 Now for some strange reason, you divide by 2
3.5y + 1.5x = 31.5 The answer is the second one down (middle one).
Since he is 6 feet tall, he starts with 6 feet above the ground and adding 1.2 each rung that he clibs so..y=mx+b ..m=slope.. b=started with...y=1.2x+6
Answer
5
Step-by-step explanation:
8n+10=50
-10 -10
8n=40
8n/8 = 40/8
n= 5
She will be able to buy 5.
DOUBLE CHECK:
8(5)+10=50
40+10=50
50=50
Answer:
2 gallons
Step-by-step explanation:
So say we make everything into cups. We know there is 4 cups in a quart and 2 cups in a pint. So if we do the math you are really adding
4 cups + 4 cups + 8 cups + 16 cups
So that would be 32 cups.
We also know there is 16 cups in a gallon. Since we know that then we can do
32 cups ÷ 16 cups
That would be 2 gallons!
Hope this helps!
