Step-by-step explanation:

Can i please get brainlist?

The measure of ∠1 in the diagram is 71 degrees.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

From the given diagram,

63 + (15x - 3) = 180°          (sum of angles on a straight line)

15x = 120

x = 8

m∠1 = 8x + 7.                       (opposite angles are equal)

m∠1 = 8(8) + 7 = 71°.

Answer:

the last option =  103 ft

Step-by-step explanation:

It is in the ratio of

1  :  30

Multiply each side by 5.5

5.5  :  165

convert 165 inches to feet

13.75

1  :  30

multiply each side by 3

3  :  90

convert 90 inches to feet

7.5

since it is asking for the area multiply 13.75 ft and 7.5 feet

13.75 * 7.5 = 103 ft

Answer:

[tex]x=\frac{1}{36} \, \,and\,\, x=-\frac{1}{36}[/tex]

Step-by-step explanation:

To find at which values of the argument the function renders 144, we need to solve for "x" in the equation when y is 144:

[tex]y=\frac{1}{9\,x^2}\\144=\frac{1}{9\,x^2}\\144\,x^2=\frac{1}{9} \\x^2=\frac{1}{9\,(144)} \\x^2=\frac{1}{1296} \\x=+/-\sqrt{\frac{1}{1296} } \\x=+/-\frac{1}{36}[/tex]

Therefore there are two solutions: one is 1/36 and the other one is its opposite; -1/36

Answer:

Step-by-step explanation:

hello :

solve : 1/9x² = 144

x² = 144×9

x² =(12×3)²    means : x² =36²

so : x=36 or x= -36

Answer:

b = [tex]\frac{2A-hc}{h}[/tex]

Step-by-step explanation:

Given

A = [tex]\frac{1}{2}[/tex] h(b + c)

Multiply both sides by 2 to clear the fraction

2A = h(b + c) ← distribute

2A = hb + hc ( subtract hc from both sides )

2A - hc = hb ( divide both sides by h )

[tex]\frac{2A-hc}{h}[/tex] = b

The cook CANNOT make 12 pizzas without refilling the canister

Step-by-step explanation:

Please see the attached files for explanation

The pizzeria cook can make 12 pizzas without refilling the flour container.

The pizzeria stores flour in a 5-gallon container. Each pizza uses 7 cups of flour. To determine if the cook can make 12 pizzas without refilling, we need to calculate if 5 gallons of flour is enough.

Calculation:

5 gallons = 640 cups (since 1 gallon = 128 cups)

12 pizzas x 7 cups/pizza = 84 cups needed for 12 pizzas

Since the canister holds 640 cups and only 84 cups are needed for 12 pizzas, the cook can indeed make 12 pizzas without refilling.

Answer:

(0, - 3 ) and (2, 1 )

Step-by-step explanation:

Given the 2 equations

y = 2x - 3 → (1)

y = x² - 3 → (2)

Substitute y = x² - 3  into (1)

x² - 3 = 2x - 3 ( subtract 2x - 3 from both sides )

x² - 2x = 0 ← factor out x from each term

x(x - 2) = 0

Equate each factor to zero and solve for x

x = 0

x - 2 = 0 ⇒ x = 2

Substitute these values into (1) for corresponding values of y

x = 0 : y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )

x = 2 : y = 2(2) - 3 = 4 - 3 = 1 ⇒ (2, 1 )

The answer is graph 3.

An exponential function is a mathematical function of the following form: f ( x ) = ax. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e, which is equal to approximately 2.71828.

Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base, and x is called the exponent. An example of an exponential function is the growth of bacteria. Some bacteria double every hour.

33

Step-by-step explanation:

The length of AC is 33. The correct option is B) 33

The diagram that illustrates the question is shown in the attachment below:

From the question,

We are to determine the length of AC.

To determine the length of AC,

First, we will determine the value of x.

From Triangle proportionality theorem,

We have that

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

Then, from the diagram, we can write that

[tex]\frac{x-3}{x-7}=\frac{x+12}{x}[/tex]

Now, we will solve for x

[tex]\frac{x-3}{x-7}=\frac{x+12}{x}[/tex]

This becomes

[tex]x(x-3) = (x-7)(x+12)[/tex]

Clearing the brackets

[tex]x^{2} -3x = x^{2} +12x-7x-84[/tex]

Simplifying, we get

[tex]x^{2} -3x = x^{2} +5x-84[/tex]

Subtract x² from both sides

[tex]x^{2}-x^{2} -3x = x^{2}-x^{2} +5x-84[/tex]

[tex]-3x = 5x-84[/tex]

Then, subtract and 5x from both sides

[tex]-3x-5x = 5x-5x-84[/tex]

[tex]-8x = -84[/tex]

Now, divide both sides by -8

[tex]\frac{-8x}{-8}=\frac{-84}{-8}[/tex]

∴ [tex]x = 10.5[/tex]

From the diagram, we can observe that the length of AC is

AC = x +12 +x

Put the value of x into the above equation

That is,

AC = 10.5 + 12 + 10.5

∴ AC = 33

Hence, the length of AC is 33. The correct option is B) 33

9(6) +5(9) +9(7)+(6(8))/2 + (6(8))/2

The surface area of the ramp will be 210 square cm. Then the correct option is B.

Let h be the height and b be the base of the triangle. Let L₁, L₂, and L₃ be the length and W be the width of the rectangle. Then the surface area of the triangular prism will be given as,

Surface area = 2 Area of triangle + 3 Area of rectangle

Surface area = (h x b) + (L₁ + L₂ + L₃) x W

Sean must determine how much paint he will use to cover all of the edges of his ramp.

The surface area of the ramp is calculated as,

SA = (8 x 6) + (5 + 6 + 7) x 9

SA = 48 + 18 x 9

SA = 48 + 162

SA = 210 square cm

The surface area of the ramp will be 210 square cm. Then the correct option is B.
