How many ways can the number 10 be written as the sum of exactly three positives and not
necessarily different integers if the order in which the sum is written does not matter? For instance,
10 = 1 + 4 + 5 is one such sum. This sum is the same as 10 = 4 + 1 + 5.
In 8 ways the number 10 can be written as the sum of exactly three positives and not necessarily different integers if the order in which the sum is written does not matter .
What is positive integers ?Positive integers are all whole numbers, both positive and negative, that are larger than zero and do not include fractions or decimals
According to the question
The ways can the number 10 be written as the sum of exactly three positives and not necessarily different integers order doesn't matter
Now ,
10 as sum of 3 positive integers
10 = 1 + 1 + 8
10 = 1 + 2 + 7
10 = 1 + 3 + 6
10 = 1 + 4 + 5
10 = 2 + 2 + 6
10 = 2 + 3 + 5
10 = 2 + 4 + 4
10 = 3 + 3 + 4
Hence, In 8 ways the number 10 can be written as the sum of exactly three positives and not necessarily different integers if the order in which the sum is written does not matter .

If f(x) = x2 + 2x + 3, what is the average rate of change of Rx) over the interval (-4, 6]?
Answer:
Step-by-step explanation:
The average rate of change of a function over an interval is simply the slope over the interval because:
[tex]let \: g(x)=f'(x)\\\frac{\int\limits^b_a {g(x)} \, dx }{b-a}(the\:average\:value\:of\:g)=\frac{f(b)-f(a)}{b-a}[/tex]
We have to know f(6) and f(-4)
[tex]f(x) = x^2 + 2x + 3\\f(6) = 6^2 + 2(6) + 3\\f(6) = 36 + 12 + 3\\f(6) = 51\\\\f(-4) = (-4)^2 + 2(-4) + 3\\f(-4) = 16 - 8 + 3\\f(-4) = 11\\\\\frac{f(6)-f(-4)}{6-(-4)} = \frac{51-11}{10} = \frac{40}{10} = 4[/tex]
Help!! I do not get it, you have to find the ratio and put it in simplest form all I need to do is letter (W)!!
Answer:
24
Step-by-step explanation:
ratios are just like fractions. The ratio would be 1200:50 but think of it like [tex]\frac{1200}{50}[/tex]
To simplify find common factors of each number
1200 and 50 can both be divided by 50 so divide each by 50
1200 ÷ 50 =24
50 ÷ 50 = 1
now your new ratio is 24:1 or just 24

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Fahrenheit temperature to Celsius temperature, the formula is C = 5 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.
Answer:
The antifreeze protects the car between -40°F and 257°F
Step-by-step explanation:
Inequalities
The range of Celsius temperatures the car's antifreeze protects the car is
[tex]-40 \le ^\circ C \le 125[/tex]
To convert °C to °F we use the formula:
[tex]\displaystyle ^\circ C=\frac{5}{9}(^\circ F-32)[/tex]
To find the equivalent range of temperatures in °F, substitute the formula:
[tex]\displaystyle -40 \le \frac{5}{9}(F-32) \le 125[/tex]
Multiply by 9, divide by 5:
[tex]\displaystyle -40*9/5 \le F-32 \le 125*9/5[/tex]
Operating:
[tex]\displaystyle -72 \le F-32 \le 225[/tex]
Adding 32:
[tex]\displaystyle -72+32 \le F \le 225+32[/tex]
Operating, we get the range of temperatures in °F:
[tex]\displaystyle -40 \le F \le 257[/tex]
The antifreeze protects the car between -40°F and 257°F
The manager of an art supply store decides to hold a Buy 2, Get 1 Free sale on tubes of watercolor paints. The sale is held for one week and a total of 280 tubes of paint were sold (not including the ones given away for free). If each tube of watercolor paint cost the store $7.25, how much money did the store lose by giving away the free tubes of paint?
Answer:
$1015
Step-by-step explanation:
280 divided by 2 140 times $7.25 is $1015
The amount of money that the store lose by giving away the free tubes of paint is $1015.
Since the manager held Buy 2, Get 1 Free sale on tubes of watercolor paints, then when 280 tubes of paints are sold, 1/2 × 280 = 140 tubes of paints will be given out for free.
Therefore, the amount lost will be calculated by multiplying the number of paints given out by the price. This will be:
= 140 × $7.25
= $1015
Therefore, the amount of money that the store lose by giving away the free tubes of paint is $1015.
