Answer:

No, he is not correct because a square can be split in to 4 equally so thats two lines of symmetry

Also,you can split it diagonally both ways.

Step-by-step explanation:

sorry for bad drawing

No, Dave is wrong.

A line of symmetry is a line that cuts a shape exactly in half.

Any figure bounded by 4 sides is called a quadrilateral.

Any 2-dimensional figure bounded by 4 sides in which all sides are equal and all the angles are 90° is called a square.

Dave said that no quadrilateral has more than two lines of symmetry.

So, the statement of Dave is wrong.

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

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.

Answer:

A and B

Step-by-step explanation:

Firstly you must establish the weight of the forklift.

You can do this by multiplying 300 by 1.75

This is 525 pounds

Now subtract 525 from 3200

This gives you 2675

Now you must Divide 2675 by 300

Then round down to find out the total number of crates that can be loaded

This is 8

So the Answer is A and B

The maximum number of crates that can fit onto the elevator is 8, given the weight constraints. Here option B is correct.

Maximum weight limit of the elevator = 3,200 pounds.

Weight of each crate = 300 pounds.

Weight of the forklift = 175% of the weight of one crate = 1.75 * 300 = 525 pounds.

To find out how many crates can fit onto the elevator, we need to consider both the weight of the crates and the weight of the forklift.

Let's denote the number of crates as x. The total weight on the elevator can be represented by the equation:

300x + 525 ≤ 3200

Solving for x:

300x + 525 ≤ 3200

300x ≤ 2675

x ≤ 8.92

Since we can't have a fraction of a crate, the maximum number of crates that can fit onto the elevator is 8. Here option B is correct.

If 300cm3 are drained out of the container,

Answer:

9.47 cm

Step-by-step explanation:

Volume of the container is given by, V= lwh where l is the length of the container, w is width and h is height.

When filled with water, taking l as 20cm, width as 14.5 cm and height as 10.5cm, the volume of container is

V=20*14.5*10.5=3045 cm3

When 300 cm3 is drained, the remaining volume is 3045-300=2745 cm3

Since the length and width is constant but height varries, the new height will be

20*14.5*H=2745

H=2745/290=9.4655172413793

Rounded off, H=9.47 cm

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

When s=10, the value of f is 22.

If s represents the score before the endgame bonus and f represents the final score, and the player receives a 12-point bonus for ending the game, then the relationship between s and f can be expressed as:

Step-by-step explanation:

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 = 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.

Answer:

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

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 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:

Step-by-step explanation: The answer is 2 fish

Alvin can have at most 2 fish in his tank to ensure the density doesn't exceed 5 fish per cubic meter.

To find out how many guppy fish Alvin can get for his water tank, we need to calculate the volume of the tank first. Given that the tank is prism-like with a base area of 0.9 square meters and a height of 0.6 meters, we can use the formula for the volume of a prism:

Volume = Base Area × Height

Substituting the given values:

Volume = 0.9 m² × 0.6 m

Volume = 0.54 cubic meters

Now, since the pet store owner advised Alvin not to exceed a density of 5 fish per cubic meter, we can calculate the maximum number of fish Alvin can get by multiplying the volume of the tank by the maximum density:

Max number of fish = Volume × Maximum density

Max number of fish = 0.54 m³ × 5 fish/m³

Max number of fish = 2.7 fish

However, since we can't have a fraction of a fish, Alvin can have at most 2 fish in his tank to ensure the density doesn't exceed 5 fish per cubic meter.
