A student's grade is a weighted calculation. Sam's grade is 83.07%

Suppose we have variables v1, v2, v3, ..., and their weights are: w1, w2, w3, ..., then the weighted average is computed by:

weighted average = v1 x w1 + v2 x w2 + v3 x w3 + ...

The following table shows the weighs and the score

Final exam                30%                  81,7%

Sam's grade = 25% x 84% + 30% x 84.7% + 15% x 81% + 30% x 81.7%

The price of car in October with respect to August is given as 112%.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Suppose the price in August be c.

Then, in September it is given as,

⇒ c - 20% × c = 4/5c

And, in October it is given as,

⇒ 4/5c + 40% × 4/5c = 28/25c

The price in October with respect to August can be obtained in percent value as follows,

Price in October ÷ Price in August × 100

⇒ 28/25c ÷ c × 100 = 112%

Hence, the price in October is 112% of the price in August.

Option c) The factor in the expression is (y³ + 7).

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product since the product is divisible by them.

An integer m that can be multiplied by another integer to create the number n is referred to as a divisor of an integer n, also known as a factor of n. One may also state that n is a multiple of m in this situation.

A factor is a number that is multiplied by another number to get the desired result. The answer to a multiplication puzzle is a product.

The variable values and measures of the side lengths of the isosceles triangle and type of triangles are;

3) x = 23, WX = WY = 95, XY = 108

4) (a) Triangle ΔDEF is a scalene triangle

(b) Triangle ΔDEF is an isosceles right triangle

An isosceles triangle is a triangle that has a two sides of the triangle which are congruent.

The specified parameters are;

[tex]\overline{WX} \cong \overline{WY}[/tex]

WX = 3 + 4·x

XY = 5·x - 7

WY = 7·x - 66

[tex]\overline{WX} = \overline{WY}[/tex], definition of congruency

3 + 4·x = 7·x - 66, by the substitution property

7·x - 4·x = 66 + 3 = 69

3·x = 69

x = 69 ÷ 3 = 23

x = 23

The length of each side are;

WX = 3 + 4 × 23 = 95

WX = 95

WY = WX = 95

XY = 5 ×23 - 7 = 108

4) The lengths of the sides of the triangle are;

(a) DE = √((-1 - 8)² + (-3 - (-6))²) = √(90) = 3·√(10)

EF = √((-2 - (-1))² + (5 - (-3))²) = √(65)

DF = √((-2 - 8)² + (5 - (-6))²) = √(221)

The length of the sides of the triangle ΔDEF are all different, indicating the triangle is a scalene triangle. ΔDEF

(b) (a) DE = √((5 - (-2))² + (5 - 3)²) = √(53)

EF = √((5 - (-4))² + (5 - 10)²) = √(106)

DF = √((-4 - (-2))² + (10 - 3)²) = √(53)

The length of DE is congruent to DF

[tex]\overline{DE}[/tex]² = 53

[tex]\overline{DF}[/tex]² = 53

[tex]\overline{EF}[/tex]² = 106

53 + 53 = 106

Therefore;

Answer:

Step-by-step explanation:

$20 + ($15/hr)(6 hr) = $110

The cost of 6 ears of corn and 4 quarts of strawberries is $24.10.

The first step is to form a system of equations using the information in the question:

12a + 3b = 20.70 equation 1

10a + 2b = 14.50 equation 2

Where:

a = cost of one ear of corn

b = cost of one quart of strawberry

The elimination method would be used to solve the above equations.

Multiply equation 1 by 2 and equation 2 by 3

24a + 6b = 41.4 equation 3

30a + 6b = 43.50 equation 4

Subtract equation 3 from equation 4

6a = 2.1

Divide both sides of the equation by 6

a = 2.10 / 6

a = $0.35

Substitute for a in equation 1:

12(0.35) + 3b = 20.70

4.2 + 3b = 20.70

3b = 20.70 - 4.20

3b = 16.50

b = 16.50 / 3

b = $5.50

Cost of 6 ears of corn and 4 quarts of strawberries = (6 x 0.36) + (4 x 5.50) = $22 + 2.1 = $24.10

The value of the inverse function [tex]f^{-1}(7)[/tex] is 2.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Let the given function is  [tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

This means, inverse of 'f' is undo operator, that takes back the effect of 'f'

We are given that f(x) = 3x+1 and [tex]f^{-1} = x-\frac{1}{3}[/tex]

The side length of the equilateral triangle is 29 inches.

What is perimeter?

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides. Area is the portion of the plane that a closed form occupies, whereas perimeter is the space surrounding the closed figure.

Here in equilateral triangle all side of the triangle is equal . Then

Perimeter of triangle = 3× side. = 3s

Now perimeter of square = 4×side = 4a

Here perimeter of an equilateral triangle is 9 inches more than the perimeter of a square

=> Perimeter of square = perimeter of triangle + 9

=> 4a = 3s+9 ---------> 1

Now side of the triangle is 5 inches longer than the side of the square.

=> s = a+5-------> 2

=> a = s-5 --------> 3

Now put 3 into 1 then,

=> 4(s-5) = 3s+9

=> 4s-20 = 3s +9

=> 4s-3s = 20+9

=> s = 29 inches.

Hence side length of the equilateral triangle is 29 inches.
