Step-by-step explanation:

The volume of a rectangular prism V is the product of its length ℓ, width w, and height h.

V=ℓwh

ou want to find how much longer the block of milk chocolate fudge is than the block of white chocolate fudge.

First, find how long the block of milk chocolate fudge is. The block of milk chocolate fudge is shaped like a rectangular prism. Its width is 6 centimeters, its height is 6 centimeters, and its volume is 504 cubic centimeters.

To find how long the block of milk chocolate fudge is, ℓ, you can use the formula for the volume of a rectangular prism.

V

= ℓwh

504

= ℓ66

504

= ℓ36 Multiply 6 by 6

506

36

=

ℓ36

36

Divide both sides by 36

14

= ℓ Simplify

The block of milk chocolate fudge is 14 centimeters long.

Now, find how long the block of white chocolate fudge is. The block of white chocolate fudge is shaped like a rectangular prism. Its width is 6 centimeters, its height is 6 centimeters, and its volume is 360 cubic centimeters.

To find how long the block of white chocolate fudge is, ℓ, you can use the formula for the volume of a rectangular prism.

V

= ℓwh

360

= ℓ66

360

= ℓ36 Multiply 6 by 6

360

36

=

ℓ36

36

Divide both sides by 36

10

= ℓ Simplify

The block of white chocolate fudge is 10 centimeters long.

Subtract to find how much longer the block of milk chocolate is than the block of white chocolate fudge.

14–10=4

The block of milk chocolate fudge is 4 centimeters longer than the block of white chocolate fudge.

Answer:

the answer is 57 I got it right hope you do to!

Step-by-step explanation:

Step-by-step explanation:

l = length

w = width

l = 3w

perimeter p = 2l + 2w = 56

using the identity of the first equation

p = 2(3w) + 2w = 56

6w + 2w = 56

8w = 56

w = 7 cm

l = 3w = 3×7 = 21 cm

so, the area is

l×w = 21×7 = 147 cm²

Answer:

D. (The one with a graph and line)

You can use the vertical line test.

By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

According to the empirical rule :

(1)   68% of the measures should come within 1 standard deviation of the mean.

(2   95% of the measures should come within 2 standard deviations of the mean.

(3)  99.7% of the measures should come within 3 standard deviations of the mean.

So we can see in this problem

The mean is 7 inches.

The standard deviation is 1.2 inches.

4.6 = 7 - 2(1.2)

9.4 = 7 + 2(1.2)

The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

The perimeter of the rectangle is the length of the boundary of the perimeter of the rectangle. The perimeter of the rectangle is 2(√29+√10).

The perimeter of the rectangle is the length of the boundary of the perimeter of the rectangle.

In order to find the perimeter of the rectangle, we need to find the third side(Hypotenuse) of each triangle, therefore,

In ΔA,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]GF^2 = 3^2+1^2\\GF=\sqrt{10}[/tex]

In ΔB,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]EF^2 = 2^2+5^2\\EF=\sqrt{29}[/tex]

In ΔC,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]GH^2 = 2^2+5^2\\GH=\sqrt{29}[/tex]

In ΔD,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]EH^2 = 3^2+1^2\\EH=\sqrt{10}[/tex]

Now, the perimeter of the rectangle is,

[tex]Perimeter\ EFGH = EF+ GF + GH +EH[/tex]

                              [tex]=\sqrt{29}+\sqrt{10}+\sqrt{29}+\sqrt{10}\\\\=2\sqrt{29}+2\sqrt{10}\\\\=2(\sqrt{29}+\sqrt{10})[/tex]    

hence, the perimeter of the rectangle is 2(√29+√10).

Step-by-step explanation:

Add the blue and red cups of paint together to get 8 1/2 cups of paint.

Since we can assume she has enough, the answer is eight and a half cups of purple paint.

Alma can make 20 cups of purple paint.

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: For every 5 cups of purple paint alma needs to add 1/2 cup of white paint .

Thus with 2 cups white paint she could make 4 batches of 5 cups of purple paint.

Therefore, total number of purple paint cups from 2 cups of white paint is

4×5=20 cupa

The measure of the angle formed by the two laser beams is 20°

An angle is formed when two or more lines intersect. Acute angles are angles less than 90 degrees, obtuse angles are greater than 90 degrees while right angles are 90 degrees.

The arc intercepted by the lasers closest to the source measures 60. The arc intercepted by the lasers on the other side of the cylinder measures 80. Hence:

The measure of the angle formed by the two laser beams = 80 - 60 = 20°

The inequalities are option B, C and D which are;

B. 11 > (w - 4)²         C. y < 3⁴           D. 5+9 < 5×9

Imbalances are numerical articulations that think about two qualities and express that they are not equivalent.

The inequalities are:

B. 11 > (w - 4)²

C. y < 3⁴

D. (5+9) < (5×9)

Here, option A and E are not inequalities. A is a quadratic expression and E is a rational function.

Inequality B says that 11 is greater than the square of the difference between w and 4.

⇒ √(11) > (w - 4)

⇒ w - 4 < √(11) or w - 4 > -√(11)

⇒ w < 4 + √(11) or w > 4 - √(11)

So the solution for inequality B is: w < 4 + √(11) or w > 4 - √(11)

Inequality C says that y is less than 3 to the fourth power (81).

⇒ y < 81

Inequality D says that the sum of 5 and 9 is less than the product of 5 and 9. This is clearly true:

⇒ (5 + 9) < (5 × 9)

⇒ 14 < 45

So the solution for inequality D is: 14 < 45

○ [tex]\displaystyle -6x^2 + 6x + 5[/tex]

Step-by-step explanation:

Since the divisor is in the form of [tex]\displaystyle x - c,[/tex]use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so do not forget it. Anyway, here is how it is done:

2| −6 18 −7 −10

↓ −12 12 10

________________

−6 6 5 0 [tex]\displaystyle \hookrightarrow -6x^2 + 6x + 5[/tex]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [−6x³ + 18x² - 7x - 10]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that −6 in your quotient can be a [tex]\displaystyle -6x^2,[/tex]the [tex]\displaystyle 6x[/tex]follows right behind it, then you end it off with [tex]\displaystyle 5,[/tex]giving you the quotient of [tex]\displaystyle -6x^2 + 6x + 5.[/tex]
