Answer:

[tex]\huge\boxed{318yd^2}[/tex]

Step-by-step explanation:

The object shown in the diagram is a triangular prism, which contains two triangular sides and three rectangular sides.

The area of a triangle is simply [tex]\frac{bh}{2}[/tex].

Because the triangles are both the same, you may multiply the equation by 2 to get simply bh, or 9 * 6, or 54.  

Then, simply solve for the areas of each rectangle:

r1 = 11 * 7 = 77

r2 = 11 * 8 = 88

r3 = 11 * 9 = 99.

Then, simply add all the values to get:

99 + 88 + 77 + 54

318.

Hope it helps :) and let me know if you want me to elaborate.

Answer:

14 minivans

Step-by-step explanation:

From the question

A total of 20 families participate in a car wash. Each family brings two cars.

Hence, the total number of cars brought to the car wash is:

20 × 2

= 40 cars.

Mr. Gonzales notices that 35% of the cars were minivans.

The number of minivans were washed is :

35% of the total number of cars

= 35/100 × 40

= 14 minivans

The y-intercept for the cubic function: 4x^3-3x^2+7 is (0, 7)

Given the polynomial function 4x^3-3x^2+7, the y-intercept of the function occurs where the value of x is zero

Substituting x = 0 into the polynomial function will give;

y = 4x^3-3x^2+7

y = 4(0)^3-3(0)^2+7

y = 0 - 0 + 7

y = 7

Hence the y-intercept for the cubic function: 4x^3-3x^2+7 is (0, 7)

Answer:

6

Step-by-step explanation:

You can solve this using Pythagorean Theorem;

a² + b² = c²

c is always the hypotenuse or the longest length in the triangle which is always opposite to the forming 90° angle.

a and b values can be the other 2 legs, doesn’t matter which one is which

we are given;

a = 8

c = 10

a² + b² = c²

(8)² + b² = (10)²

64 + b² = 100

b² = 100 - 64

b² = 36

√b² = √36

b = 6

Therefore the answer = 6

Answer: [tex]2x^{2} + 5x -3[/tex]

Step-by-step explanation:

Find the quotient of  [tex]\frac{16x^4+40x^3-24x^2}{8x^2}[/tex]

Step 1: Break down the polynomial equation

[tex]\frac{16x^4}{8x^2}[/tex] + [tex]\frac{40x^3}{8x^2}[/tex] - [tex]\frac{24x^2}{8x^2}[/tex]

Step 2: Divide each piece by dividing the coeffients and subtracting the variables.

16 ÷ 8 = 2

[tex]x^{4}[/tex] - [tex]x^{2}[/tex] = [tex]x^{2}[/tex] → 2[tex]x^{2}[/tex]

40 ÷ 8 = 5

[tex]x^{3}[/tex] - [tex]x^{2}[/tex] = [tex]x[/tex] → 5[tex]x[/tex]

- 24 ÷ 8 = - 3

[tex]x^{2}[/tex] - [tex]x^{2}[/tex] = 1 → - 3

Step 3: Put the polynomial together

2[tex]x^{2}[/tex] + 5[tex]x[/tex] - 3

  1. y = 1/4x +4 1/4

  2. y = -5/9x +7/9

Step-by-step explanation:

The relevant formulas are ...

  m = (y2 -y1)/(x2 -x1) . . . . . slope of line through points (x1, y1), (x2, y2)

  b = y -mx . . . . . . . . . . . . . y-intercept of a line with slope m through point (x, y)

  y = mx + b . . . . . . slope-intercept equation of the line

__

Points (3, 5), (-1, 4)

  m = (4 -5)/(-1 -3) = -1/-4 = 1/4

  b = 4 -(1/4)(-1) = 4 1/4

Equation of the line: y = 1/4x + 4 1/4

__

Points (-4, 3), (5, -2)

  m = (-2-3)/(5 -(-4)) = -5/9

  b = 3 -(-5/9)(-4) = 3 -20/9 = 7/9

Equation of the line: y = -5/9x +7/9

Answer:

The first set is a solution, the second is not.

Step-by-step explanation:

Testing by filling in the numbers into the equation:

(1, 1.5): x=1, y=1.5

⇒ 1.5 =? [tex]\frac{1}{4}[/tex] · 1 + [tex]\frac{5}{4}[/tex]

⇒ 1.5 =? [tex]\frac{1}{4}[/tex] + [tex]\frac{5}{4}[/tex]

⇒ 1.5 =? [tex]\frac{6}{4}[/tex]

⇒ 1.5 =? 1.5  ⇒ Correct: is indeed solution to the equation

(12, 4): x=12, y=4

⇒ 4 =? [tex]\frac{1}{4}[/tex] · 12 + [tex]\frac{5}{4}[/tex]

⇒ 4 =? [tex]\frac{12}{4}[/tex]  + [tex]\frac{5}{4}[/tex]

⇒ 4 =? [tex]\frac{17}{4}[/tex] ⇒ Incorrect: this is not a solution for the equation

Answer:

v = -1/2

Step-by-step explanation:

-4(v+1) = 2v - 2 + 2(3v + 2)

-4v - 4 = 2v - 2 + 6v + 4

-4v - 4 = 8v + 2

-4 = 12v + 2

-6 = 12v

-6/12 = v

v = -1/2

[tex] \frac{3}{10y} - \frac{2}{5} = \frac{3 - 4y}{10y} [/tex]

Step-by-step explanation:

I guess, this expression really is

-9k² + 6k² - 7k² - 5k² + -8k² + -2k²

remember : all terms with the same base reference (either a number or a variable with the same exponent, or a function ...) can be combined.

all the terms in this expression are about k². so we can combine them all

k² × (-9 + 6 - 7 - 5 - 8 - 2) =

k² × -25 or simply -25k²

always also remember the rules of combining signs and operations :

++ = +

+- = -

-+ = -

-- = +
