A triangle has side lengths of 12 inches 14 inches, and 18 inches. What best represents the perimeter of the triangle in centimeters? (1 inch ~ 2.54 centimeters)
Answer:
111.76 cm
Step-by-step explanation:
The formula for the perimeter of a triangle is given as:
Side A + Side B + Side C
Since our final answer is going to be in centimeters we have to convert the sides from inches to centimeters
Hence:
1 inch ~ 2.54 centimeters
For 12 inches
1 inch = 2.54 cm
12 inches = x
Cross Multiply
x = 12× 2.54 cm
x = 30.48 cm
For 14 inches
1 inch = 2.54 cm
14 inches = x
Cross Multiply
x = 14× 2.54 cm
x = 35.56 cm
For 18 inches
1 inch = 2.54 cm
18 inches = x
Cross Multiply
x = 18× 2.54 cm
x = 45.72 cm
Hence, the perimeter of the triangle
= 30.48 cm + 35.56 cm + 45.72 cm
= 111.76 cm

What is the equation of the line that passes through the point (−2,1) and has a slope of -5/2
Answer:
You need to make turn this information into slope intercept form: y = mx + b. The m is your slope, the b is your y-intercept. x and y represents the coordinates that the line passes through. Make y = 1, make m = -2, and make x = 2, and you will get: 1 = -2(2) + b. When you simplify, you get 1 = -4 + b, add 4 to both sides and you'll get 5. So my equation is y = -2x + 5. Remember the -2 came from the slope! To get b, substitute the (2,1) in for (x,y) in the equation.

Step-by-step explanation:
y is directly proportional to x
y=kx
Find Constant K, when y=30 & x=6
Make K the subject of the formula first
K=y/x
K=30/6
k=5
When k is 5, x is 12, find y
y=kx
y=5×12
y=60

Addison prepared 30 kilograms of dough after working 3 hours. How many hours did Addison work if she prepared 50 kilograms of dough? Assume the relationship is directly proportional.
Answer:
Addison worked 5 hours
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
The relationship between the number of kilograms of dough Addison prepares (y) is proportional to the number of hours he works on it (x).
Knowing he prepared y=30 kilograms of dough after t=3 hours, we substitute in the function:
30 = 3k
Solving for k:
k = 30/3 = 10
The relationship is:
y = 10x
If he prepared y=50 kg of dough, then:
50 = 10x
Solving for x
x = 50/10 = 5
Addison worked 5 hours

the difference of 2 times d minus 3
4 added to the difference of d minus 3
the difference of d minus 3 divided by 2
the quotient of 12 divided by the
difference of 3 times d minus 3
Answer:
the difference of 2 times d minus 3= 6
4 added to the difference of d minus 3= 4
the difference of d minus 3 divided by 2= 0
the quotient of 12 divided by the difference of 3 times d minus 3= 2
Step-by-step explanation:
2 times 3 equals 6. 3 minus 3 equals 0. 6-0=6
d minus 3 equals 0. 4+0 equals 4
3 minus d equals 0. 0 divided by two is 0
3 times d= 9. minus 3 = 6. 12 divided by 6 = 2

The correct pairs are:
The difference of 2 times d minus 3 --> 3
4 added to the difference of d minus 3 --> 4
The difference of d minus 3 divided by 2 --> 0
The quotient of 12 divided by the difference of 3 times d minus 3 --> 2

A recipe for pie dough calls for a ratio of butter to flour of 23 : 134. If you plan to use 7 cups of flour, how much butter should you use to keep the same ratio?
Answer:
You might have to round, but ≈1.2015
Step-by-step explanation:
butter: flour
23 : 134 is really just a:b
b = 7, so: a : 7
Divide both sides by 134, so
≈0.172 : 1
Multiply by 7 to get 7 cups of flour
≈1.2:7
