What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measures 14 inches.
As we know, in the triangle, the sum of the two sides is equal and greater than the third side.
Mathematically,
x + y ≥ z
Here x, y, and z are the sides of the triangle.
12 + 14 ≥ x
x ≤ 26
The greatest possible whole-number length of the unknown side is 9 inches.
Thus, the greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.

if a person walks 1/2 mile in 1/4 hour, how far does that person walk in 1 3/4 hours at that rate?
Answer:
3 1/2 miles
Step-by-step explanation:
We can use a ratio to solve
1/2 mile x miles
----------------= ---------------
1/4 hour 1 3/4 hours
Changing to improper fractions
1/2 mile x miles
----------------= ---------------
1/4 hour 7/4 hours
Using cross products
1/2 * 7/4 = 1/4x
7/8 = 1/4x
Multiply each side by 4
7/2 = x
Changing back to a mixed number
3 1/2 =x

Arthur is organising his collection
of DVDs. He has 56 altogether.
The ratio of comedy films to
action to horror is 2 : 7:5
Step-by-step explanation:
x - is the amount of DVDs
so 2x + 5x + 7x = 56
14x = 56
x = 4
so comedy is 2x4 = 8; action 7x4 = 28 and horror is 5x4 = 20 DVDs

there are 88 girls and 96 boys in the sixth-grade what is the rate of girls to boys
A- 88 girls for every 96 boys
B- i girl for every 1.09 boys
C- 44 girls for every 48 boys
D- 11 girls for every 12 boys
Answer:
There are 11 Girls for every 12 Boys in the sixth-grade class
Step-by-step explanation:
For this problem, you want to take the original rate which is 88 girls / 96 boys.
Once you have that number, you want to divide both sides by 8.
88/96 = 11/12
The correct option is D. 11 girls for every 12 boys.
We need to determine the ratio of the number of girls to the number of boys.
Given:
Number of girls = 88
Number of boys = 96
The ratio of girls to boys can be represented as "girls : boys."
To simplify the ratio, we can divide both the number of girls and the number of boys by their greatest common divisor (GCD). In this case, the GCD of 88 and 96 is 8.
Dividing both numbers by 8, we get:
Number of girls (after dividing) = 88 ÷ 8 = 11
Number of boys (after dividing) = 96 ÷ 8 = 12
So, the simplified ratio of girls to boys is 11 : 12.
Now, let's check which option matches the simplified ratio:
A. 88 girls for every 96 boys (Does not match)
B. 1 girl for every 1.09 boys (Does not match)
C. 44 girls for every 48 boys (Does not match)
D. 11 girls for every 12 boys (Matches)
The correct option is D. 11 girls for every 12 boys.

Step-by-step explanation:
What is the value of x in the equation 6(x +11)= -300?
Answer:
-61
Step-by-step explanation:
We use the distributive property to distribute 6 to both x and 11. This gives 6x+66=-300. Subtracting both sides by 66 gives 6x=-366. Dividing both sides gives x=-61.

how do you calculate the profit
Answer:
total money - total expences = profit
Total money is the money you make, so say you made $50
Total expences is how much you paid to have that thing made, say $10
50 - 10 = 40
the profit would then be $40
A family of four drove from San Francisco to New York. They drove the same number of miles each 6 days. How many miles did they drive each day? How can you interpret the remainder?
Answer:
Step-by-step explanation:
Approximate distance between San Francisco and New York = 2903 miles
Number of family members = 4
Approximate distance to be covered by each member per day = [tex]\frac{2903}{4}[/tex] = [tex]725\frac{3}{4}[/tex] miles
Number of days to drive = 6 days
Total distance to be covered by each member each day = [tex]\frac{2903}{4}\times \frac{1}{6}[/tex]
= [tex]\frac{2903}{24}[/tex]
= [tex]120\frac{23}{24}[/tex] miles
Therefore, each family member has to drive the car for 120 miles per day approximately.
23 miles remaining will be covered by any one of the family members on the last day.
