Corey drew a sketch of a paper hat


If a = 4 in and b = 3 in, what is the area of the sketch?
A.
84 in2
B.
60 in2
C.
40 in2
D.
21.5 in

Steps to solve:

-3(x + 4) = 15

~Distributive Property

(-3 * x) + (-3 * 4) = 15

~Simplify

-3x - 12 = 15

~Add 12 to both sides

-3x - 12 + 12 = 15 + 12

~Simplify

-3x = 27

~Divide -3 to both sides

-3x/-3 = 27/-3

~Simplify

x = -9

Best of Luck!

Answer:

I need an angle to find the degrase.

Answer:

D)151

Step-by-step explanation:

61° + 90° = 151°

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

30 gallons of water weighs 250 pounds.

To find the weight of 30 gallons of water, we can use the given conversion factor that 1 gallon of water weighs 8 1/3 pounds.

First, let's find the weight of 1 gallon of water in pounds:

1 gallon = 8 1/3 pounds

Now, we can calculate the weight of 30 gallons of water:

30 gallons = 30 x (8 1/3 pounds)

= 30 x (25/3 pounds)

= 250 pounds

Therefore, 30 gallons of water weighs 250 pounds.

find the area of each rectangle and add it to the area of both the triangles

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.

A. Always

Two lines don't always intersect, but the solutions are always where they intersect.

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 )

Answer:

(0, - 3 ) and (2, 1 ) 100% correct

Step-by-step explanation:

Answer:

y = (x- 2)^2 + 1

Step-by-step explanation:

Because the vertex is at (2, 1)

so  the equation is y = (x- 2)^2 + 1

Answer:

c

Step-by-step explanation:

moving the figure over 7 units would put it directly over the a'

after that you can reflect the a over the x axis

The correct option is C. Translate [tex]7 \ units[/tex] to the right and then reflect over the x-axis.

To determine the transformations that map triangle [tex]\( A \)[/tex] to triangle [tex]\( A' \)[/tex]

1. Translation:

Observe the horizontal distance between the corresponding points of triangles [tex]\( A \)[/tex] and [tex]\( A' \)[/tex].

Triangle [tex]\( A \)[/tex] is initially centered around [tex]\( x = 2 \)[/tex]., while triangle [tex]\( A' \)[/tex] is centered around [tex]\( x = 2 \)[/tex]

The horizontal distance from [tex]\(-5\)[/tex] to [tex]\(2\)[/tex] is [tex]\(7\)[/tex] units to the right.

2. Reflection:

Check the vertical positions of triangles [tex]\( A \)[/tex] and [tex]\( A' \)[/tex].

Triangle [tex]\( A \)[/tex] is above the x-axis while triangle [tex]\( A' \)[/tex] is below the x-axis. This indicates a reflection over the x-axis.

Thus, the correct transformation sequence is to translate triangle [tex]\( A \) 7 units[/tex] to the right and then reflect it over the x-axis.

Answer:

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.

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°.
