20. GEOMETRY The measures of two sides of a triangle are given. If p isthe perimeter, and p=10x+5y, find the measure of the thir
algol [13]

The perimeter of any shape is a measure of the length of the peripheral of that shape.

For a triangle, it is an addition of the length of the 3 sides.

P = a + b + c where a, b, c are the lengths of the individual sides.

p = 10x + 5y = (3x + 4y) + (5x - y) + c

Collecting like terms on the RHS, we have

p = 10x + 5y = 8x + 3y + c

Subtracting 8x + 3y from both sides to give c leaves us with

10x + 5y - (8x + 3y) = c

c = 10x - 8x + 5y - 3y

c = 2x + 2y

.Shaun estimated that the attendance at a college
Serggg [28]

Answer:

38.72%

Step-by-step explanation:

Estimated attendance = 1,000

The actual value of attendance = 1,632

We need to find the percent error of Shaun's estimate. Using the formula as follows :

\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100

Put all the values,

\%=\dfrac{1632-1000}{1632}\times 100\\\\=38.72\%

So, the percent error of Shaun's estimate is 38.72%.

1. COST Mr. Rivera wants to purchase a riding lawn
antiseptic1488 [7]

Answer:

p(x) = 0.85x

t(x) = 1.065x

(t o p)(x) = 0.9x

$2700

Step-by-step explanation:

If the marked price is $x, then the function p(x) that gives the price of the riding lawn mower after 15% discount will be

p(x) = x(1 - \frac{15}{100}) = 0.85x

where x is the marked price.

Now, the function that gives the total cost with sales tax will be given by

t(x) = x(1 + \frac{6.5}{100}) = 1.065x

where x is the discounted price.

Therefore, the composite function that gives the total cost of the riding lawn mower on sale is given by

(t o p)(x) = 1.065(0.85x) = 0.9x ............ (1)

where x is the marked price.

If the marked price x = $3000, then Mr. Rivera has to pay for the riding lawn mower, from equation (1),

(t o p)(3000) = 0.9 × 3000 = 2700 dollars. (Answer)
