Perimeter:
 The perimeter of the triangle is the sum of its sides.
 We have then:
 P = 8 + 12 + 10
 P = 30 units

 Semi-perimeter: 
 In geometry, the semiperimeter of a polygon is half its perimeter.
 s = P / 2
 s = 30/2
 s = 15 units.

 Area: 
 Knowing the semiperimeter and the sides, the area is:
 A = root (s * (s-a) * (s-b) * (s-c))
 where,
 s: semi-meter
 a, b, c are sides.
 A = root (15 * (15-8) * (15-12) * (15-10))
 A = 39.68626967
 A = 40 units ^ 2

A recipe requires 3/4 cups of water targa has a measuring cup that is marked only in ounce but she knows that 8 ounces is equiva
bulgar [2K]

Answer:

6 ounces of water

Step-by-step explanation:

In this question, we are asked to calculate the amount in ounce that would be added to the recipe.

From the question, we can see that the recipe requires 3/4 cups of water.

From the question also, we can also see that one cup equals 8 ounces.

Now to know the amount of water that is to be added, what we need to do is to simply multiply the fraction of water in the recipe by 8 ounces

This is equal to 3/4 * 8 = 6 ounces

Hence, she needs to add a total of 6 ounces of water to the recipe

A bank loaned out 16,000 ​$​, part of it at the rate of 6% per year and the rest at 14% per year. If the interest received in on
MakcuM [25]

Answer:

This question requires a comparison between two different variables 6% and 16% values.  If we let x=$ loaned on 6% loans and y=$ loaned on 16% loans, then we can relate two equations.

0.06x + 0.16y = $1500  --> referencing the interest earned from each percentage loaned.

x + y = $16000  --> referencing the total amount of money loaned out.

Rearrange either equation and substitute for a value in the other equation or use elimination to determine each individual variable.

We're told x=-5 and y=11 and asked to evaluate a few expressions. That just means substitute these values into the expressions and compute the exact numerical answer.

4y-10x = 4(11) - 10(-5) = 44 + 50 = 94

Answer: 94

x to the power of 3

x^3 = (-5)^3 = -5 \times -5 \times -5 = -125

Answer: -125

•6y to the power of 2

Probably means

6y^2 = 6(11)^2 = 6(121) = 726

Answer: 726

5(3x+2y) = 5(3(-5) + 2(11)) = 5(-15 + 22) = 5(7) = 35

Answer: 35

•(y-x) to the power of 2

(y - x)^2 = (11 - -5)^2 = 16^2 = 256

Answer: 256
