Answer:

Length of the prism is 18.8958cm (Rounded off to four decimal places)

Step-by-step explanation:

Volume of a rectangular prism     = Length * Width * Height

Volume of the rectangular prism  = [tex]1334cm^{3}[/tex]

Width of the prism                          = 8cm

Height of the prism                         = 12cm

We need to find the length of the Prism,

For that first make the Length as subject of the equation,

Length = [Volume of the rectangular prism/(Width * Height)]

            =[tex]1334cm^{3}[/tex]/(8cm*12cm)

            =[tex]1334cm^{3}[/tex]/[tex]96cm^{2}[/tex]

            =18.8958cm (Rounded off to four decimal places)

-5c + 6 = -69

-5c = - 75

c = 15

6c - 15

Answer:

Top-to-bottom, the boxes have this order in the proof: 1, 7, 4, 3, 9, 8, 5, 2, 6.

Step-by-step explanation:

The basic idea is to use the Pythagorean theorem to write two expressions for the length of altitude BD, also called "k", then equate them and simplify the result. This leaves an expression for DC, also called "x", which is replaced by a cosine expression to complete the proof.

Finally, the variations involving other combinations of sides and angles are suggested as being provable in the same way.

Question 4: The correct option is d. Multiplying by 2 stretches the graph of g(x) = 2⌈x⌉ vertically by a factor of 2.

Question 5: The correct option is a. The graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted down 3 units.

Question 4:

The graph illustrates the functions f(x) = ⌈x⌉ and g(x) = 2⌈x⌉. Multiplying by 2 does not compress or shift the graph vertically, but rather stretches it. Each step on f(x) has a height of 1 unit, while on g(x), the steps have a height of 2 units.

This indicates that g(x) is a vertical stretch of f(x) by a factor of 2. The red dotted lines highlight the vertical distance between corresponding steps of f(x) and g(x), showing that g(x) is indeed twice the height of f(x) at every step. Therefore, the correct statement is:

Multiplying by 2 stretches the graph of g(x) = 2⌈x⌉ vertically by a factor of 2.

The representation of the graph is given below.

Question 5:

The graph demonstrates the functions f(x) = ⌊x⌋ and g(x) = ⌊x⌋−3. The graph of g(x) is identical in shape to the graph of f(x), but it is shifted downward by 3 units. This is visually represented by the dashed line of g(x), which follows the same step pattern as f(x) but is consistently 3 units lower across the entire domain.

Therefore, the correct statement is:

The graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted down 3 units.

The representation of the graph is given below.

1/2 Hour = 20 Minutes

Answer: $750

Step-by-step explanation:

If the band is earning $1,500 on ticket sales, that is equal to 2/3 aka 6/15. 1/5,or, 3/15 is earned on merchandise. Since 3/15 is half of 6/15, that means that merchandise makes half of $1,500, (1500÷2) or $750.

So, the band earns $750 from merchandise

750

( - 10, - 22 )

using the midpoint formula,

let the other endpoint have coordinates (x, y) then

[tex]\frac{1}{2}[/tex] (2 + x ) = - 4 ( multiply through by 2 )

2 + x = - 8 ( subtract 2 from both sides ) then

x = -8 - 2 = - 10 ← value of x-coordinate

Similarly for y-coordinate

[tex]\frac{1}{2}[/tex] (8 + y ) = - 7 ( multiply through by 2 )

8 + y = - 14 ( subtract 8 from both sides )

y = - 14 - 8 = - 22 ← y -coordinate

the other endpoint is ( - 10, - 22 )

The band makes $300 from selling merchandise.

I found this out by finding the LCD for 3 and 5, which is 15.

Then I multiplied the 2 from 2/3 by 5, and the 1 from 1/5 by 3, which results in 10/15 and 3/15.

Next I divided 1500 by 15, which is 100.

Then I multiplied 100 by 3, and got 300.

The band earns $450 from selling merchandise.

To find out how much money the band earns from selling merchandise, we need to determine what fraction of their profit comes from merchandise sales. We know that the band earns 2/3 of their profit from selling concert tickets, which equals $1500. Let's use this information to find the total profit.

Since 2/3 of the profit is $1500, we can find the total profit by multiplying $1500 by 3/2. $1500 x 3/2 = $2250. Therefore, the total profit the band earns is $2250.

Next, we need to find out how much money the band earns from selling merchandise, which is 1/5 of the total profit. To find this amount, we can multiply the total profit of $2250 by 1/5. $2250 x 1/5 = $450. So, the band earns $450 from selling merchandise.

If the sum of the base and the height are 30, then b+h=30 or h=b-30.

Remember that the area of any triangle is A=½bh.

If you substitute in b-30 for h, then you create a function for the area in terms of the base.

A = ½b(30-b)=15b-½b2

The maximum area would be at the vertex of the parabola that would result from the function.  We can graph to find the max, but there is a simple formula for the x-coordinate of the vertex: -b/2a where b=the linear coefficient and a=the quadratic coefficient.

-15/2(-½)=15  meaning that a base of 15cm would provide the maximum area.  The corresponding height would be 30-15 or 15cm as well.

Mark me as  brainlest plz

The maximum area of a triangle where height plus base equals 30 cm occurs when both the base and height of the triangle are 15 cm each.

This is a problem of maximization. It's based on the principle that a right triangle will have its largest area when the two legs (in this case, the base and the height) are equal. This maximizes the product of the two dimensions. As a result, both the base and the height of the triangle are each 15 cm.

Here are the steps to confirm this: let's denote the base as b and the height as h. The area (A) of a triangle is given by the formula A = 0.5*b*h. Given that the sum of base and height is 30 cm (b + h = 30), we can substitute h = 30 - b into the area formula, giving A = 0.5*b*(30 - b).

By applying the quadratic formula, you find that the maximum area of the triangle is achieved when b = 15 cm. Because the sum of base and height is 30, we then find that h = 15 cm.

So, for maximum area, both base and height should be 15 cm.

Choose an object and rotate it up to 180 degrees around its center. If at any point the object appears exactly like it did before the rotation, then the object has rotational symmetry.

Step-by-step explanation:

We are asked to determine when does a figure have rotational symmetry.

We know a figure has a rotational symmetry, when the figure maps onto itself after rotating it less than 180 degrees.  

In other words, we can say it is the property that a shape has when it looks the exactly same after some rotation.

When a figure maps onto itself exactly at 180 degrees, then the figure has a point symmetry.

Therefore, a figure has rotational symmetry if it maps onto itself after a rotation less than 180 degrees.

To solve this question, we can start to set up an equation using what the question is telling us. Since we don't know what the number is, let's make it equal to x.

The phrase "5 times a number" means that we're multiplying our unknown, x, by 5. That is equal to 5x. 9 less than that would be 5x - 9. Since we know that it's equal to -30, we can solve.

5x - 9 = -30

Get all terms with x on one side and the constants on the other

5x - 9 +9 = -30 + 9

Simplify

5x = -21

Now, we can divide both sides by 5 to get our answer of x = -[tex]\frac{21}{5}[/tex]

An equation can be formed with the given information.

"Nine less than" → -9

"Five times a number" → 5x

"Is equal to -30" → =-30

So our given equation is: 5x-9=-30

To solve this, first add 9 on both sides of the equation.

5x-9+9=-30+9

5x=-21

Divide both sides by 5 for x.

[tex]\frac{5x}{5}[/tex]=[tex]\frac{-21}{5}[/tex]

x=[tex]\frac{-21}{5}[/tex] , or -4.2.

The three consecutive numbers are 25,27,29. The smallest is 25

In order to solve this, first add 10p on both sides of the equation to get the variable on one side only.

[tex]-8p-10=-10p+10[/tex]

[tex]-8p+10p-10=-10p+10p+10[/tex]

[tex]2p-10=10[/tex]

Now add 10 on both sides of the equation.

[tex]2p-10+10=10+10[/tex]

[tex]2p=20[/tex]

Divide both sides by 2 for x.

[tex]\frac{2p}{2}[/tex]=[tex]\frac{20}{2}[/tex]

[tex]p=10[/tex]

Hello!

Answer: ⇒⇒⇒⇒⇒⇒⇒ p=10

Step-by-step explanation:

First you had to add by 10 from both sides of equation.

[tex]-8p-10+10=-10p+10+10[/tex]

Simplify.

[tex]-8p=-10p+20[/tex]

Add by 10p from both sides of equation.

[tex]-8p+10p=-10p+20+10p[/tex]

Simplify.

[tex]2p=20[/tex]

Divide by 2 from both sides of equation.

[tex]\frac{2p}{2}=\frac{20}{2}[/tex]

Simplify.

[tex]p=10[/tex]
