Final answer:

To express 112 as a product of prime numbers in index form, we perform prime factorization to get 2⁴ x 7.

Explanation:

To express 112 as a product of prime numbers in index form, we start by performing prime factorization, which is breaking down a composite number into the prime numbers that, when multiplied together, give the original number.

Let's find the prime factors of 112:

112 is divisible by 2 (the smallest prime number).112 ÷ 2 = 5656 is also divisible by 2, so 56 ÷ 2 = 28Continuing this process, 28 ÷ 2 = 14, and then 14 ÷ 2 = 7The number 7 is a prime number and cannot be divided further.

So, we can express 112 as a product of prime factors as 2⁴ × 7¹ or simply 2⁴ × 7, since any number to the power of 1 is the number itself.

Katlin divided a fraction by 1/2 the result was a mixed number. was the fraction less than or greater than 1/2? EXPLAIN.

Answers

The fraction was greater than 1/2.

When you divide by a fraction, it is equal to multiplying by its reciprocal. The reciprocal of 1/2 is 2/1, or just 2. Therefore, dividing by 1/2 equals the same thing as when you multiply by 2.

A mixed number has a whole number and a fraction added together. So, the mixed number must be greater than 1.

1/2 is equal to 0.5, and 0.5 multiplied by 2 equals 1. A fraction less than 1/2 multiplied by 2 would equal a number less than 1, while a fraction greater than 1/2 would equal a number greater than 1.

Because a mixed number must be greater than 1, and a fraction greater than 1/2 multiplied by 2 would be greater than 1, the fraction that resulted in a mixed number after being multiplied by 2 must have been greater than 1/2.

A linear equation represents an equation that has one or multiple variables with the highest power of the variable is 1.

The given equation is:

y - 3 = x - 4

⇒ y = x - 1

Therefore, for x = 0, y = - 1

for x = 1, y = 0

for x = - 1, y = - 2

Therefore, the graph will pass through points (0, - 1), (1, 0), (- 1, - 2).

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?

Answers

The volume of a cone  is 1/3 pi R^2 H    where R = radius of the base of the cone and hH= height of the cone

her H = r and R  = 0.5r  so the volume of the cone is
  1/3 * pi * (0.5r)^2 * r

  = 1/3 * pi *  0.25 r^3

= (1/12) pi r^3      Answer

Answer:

Volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]

Step-by-step explanation:

Formula to find the volume of a cone is V = [tex]\frac{1}{3}\pi r^{2}h[/tex]

Here r is the radius of the cone and h is the height of the cone.

Since radius of cone = [tex]\frac{1}{2}(\text{Radius of cylinder})[/tex]

                                  = [tex]\frac{r}{2}[/tex]

Height of the cone = radius of the cylinder = r

Now we put the values of radius and height of cone in the formula

Volume of cone = [tex]\frac{1}{3}\pi (\frac{r}{2})^{2}(r)[/tex]

= [tex]\frac{1}{3}\pi(\frac{r^{2}}{4})(r)[/tex]

= [tex]\frac{1}{12}\pi r^{3}[/tex]

Therefore, volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]

Answers

To find area of a circle, one must perform the equation "pi(r)^2" we have all information but the radius which has become inclusive in the question. To draw out the radius, all you gotta do is defuse 64 into its square root-8. The radius is 8.

we know that

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

where

r is the radius of the circle

In this problem we have

[tex]A=64\pi \ ft^{2}[/tex]

substitute in the formula and solve for r

[tex]64\pi=\pi r^{2}[/tex]

Simplify

[tex]64=r^{2}[/tex]

Square root both sides

[tex]r=8\ ft[/tex]

Figure ABCD is a parallelogram

Answers

I think that 7 = x because 5*7=35 and 35+3=38

Answer:

x = 7

Step-by-step explanation:

Figure ABCD is a parallelogram

So sides AD and BC will be parallel and their length will be same.

[Since opposite sides of parallelogram are equal in length]

So mAD = mBC

(5x + 3) = 38

5x = 38 - 3 = 35

x = [tex]\frac{35}{5}[/tex]

x = 7

Therefore, x = 7 will be the answer.

James buys a shirt and a pair of socks on sale for 25% off. if the price of the shirt before the sale was $24 and he spent a total of $24, what was the original price of the socks?

Answers

The price of the socks are $8

Answer:

The original price of socks was $8.

Step-by-step explanation:

James buys a shirt and a pair of socks on sale for 25% off.

The price of the shirt before the sale was $24 that means after discount the price was:

[tex]24-(0.25\times24)[/tex] = $18

And James paid a total of $24.

That means the price of socks after discount is = [tex]24-18[/tex] = $6

Let the original price of socks be x. And after 25% discount, it was for $6.

So, [tex]x-0.25x=6[/tex]

=> [tex]0.75x=6[/tex]

x = 8.

Hence, the original price of socks was $8.

A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t² + 704t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit.

Answers

h(t) = -16t^2 +704t = -16(t^2 -44t)
Putting in vertex form: -16(t^2 -44t +484) + 704
h(t) = -16(t-22)^2 + 704
It takes 22 seconds to reach the maximum height, which is the vertex of the parabola at (22,704)

Answer:

22 secs.

Step-by-step explanation:

h(t) = -16t^2 + 704t

The maximum will happen where the first derivative is equal to 0.

h’(t) = -32t + 704

-32t + 704 = 0 => -32t = -704 After subtracting 704 from both sides of the equation

Now divide both sides of the equation by -32

t = 22 secs.

Double Check: recalculated/reasonable ✅ ✅

Answer: 22 secs.

Just an interesting aside. After 22 secs, the projectile will be -16(22)^2 + 704(22) = -7744 + 15,488 = 7744 units up as its maximum height.

Final answer:

The length of each side of the tablecloth is 13 inches.

Explanation:

To find the length of each side of the tablecloth, we need to take the square root of the area. Since the area is given as 169 square inches, we can take the square root of 169. The square root of 169 is 13, so each side of the tablecloth is 13 inches long.

what translation rule can be used to describe the result of the composition of (x,y) --> (x - 9,y - 2) and (x,y) --> (x + 1, y - 2) ? PLEASE HELPPPPP!!!!!

Answers

we know that

the rule of the translation A is

[tex](x,y)-----> (x-9,y-2)[/tex]

that means

the translation is [tex]9[/tex] units to the left and [tex]2[/tex] units down

the rule of the translation B is

[tex](x,y)-----> (x+1,y-2)[/tex]

that means

the translation is [tex]1[/tex] unit to the right and [tex]2[/tex] units down

therefore

the rule of the composition A+B is

[tex](x,y)-----> (x-9+1,y-2-2)[/tex]

[tex](x,y)-----> (x-8,y-4)[/tex]

that means

the translation is [tex]8[/tex] units to the left and [tex]4[/tex] units down

so

the answer is

[tex](x,y)-----> (x-8,y-4)[/tex]

Final answer:

The translation rule that describes the result of the composition of the transformations (x, y) --> (x - 9, y - 2) and (x, y) --> (x + 1, y - 2) is (x, y) --> (x - 8, y - 4). This rule is obtained by sequentially applying each transformation to (x, y).

Explanation:

When we talk about compositions of translations in geometry, what we are doing is carrying out one translation after the other. So, if we have two translations: (x, y) --> (x - 9, y - 2) and (x, y) --> (x + 1, y - 2), we perform these operations sequentially.

First, we apply the transformation (x,y) --> (x - 9, y - 2). Then we take these new coordinates and apply the second transformation (x,y) --> (x + 1, y - 2). The result of this composition is (x - 9 + 1, y - 2 - 2) = (x - 8, y - 4), as you add (or subtract) the changes introduced by each translation.

So, the translation rule that can be used to describe the result of the composition of these transformations is: (x, y) --> (x - 8, y - 4).

What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?

Answers

 

Rewrite the given equation in slope intercept form:

5 y = 10 – 2 x

y = - 0.4 x + 2

 

Since the two lines are parallel, therefore they have similar slope which is – 0.4, so the equation is:

y = - 0.4 x + b

Given that x = 5, y = -4, find for b:

-4 = - 0.4 (5) + b

b = -2

 

So the answer is:

y = - 0.4 x – 2

or

2 x + 5 y = - 10

If it costs a restaurant​ $11.90 to produce 2 white chocolate tortes and each torte is cut into 8​ slices, how much does each slice cost to​ make?

Answers

Ok so:

so 1 torte has 8 slices, but you have to do 8 + 8 = 16

11.90 is how much you have to pay for 2 tortes with a total of 16 slices.

All you have to do now is divide: 11.90 / 16

It costs $0.74 to produce just one slice.

Hope I helped :D

Final answer:

To find the cost of each slice of white chocolate torte, divide the total cost to produce two tortes ($11.90) by the total number of slices (16), resulting in approximately 74 cents per slice.

Explanation:

Cost of Each Slice of White Chocolate Torte

To calculate the cost of each slice of white chocolate torte, we start by determining the total cost of producing the tortes. The restaurant's cost is $11.90 for 2 tortes, and each torte is cut into 8 slices. This means there's a total of 2 tortes × 8 slices/torte = 16 slices. Dividing the total cost by the number of slices gives us the cost per slice:

Total cost for 2 tortes: $11.90

Number of slices per torte: 8

Total number of slices: 2 tortes × 8 slices/torte = 16 slices

Cost per slice: $11.90 / 16 slices = $0.74375 per slice

Therefore, each slice costs approximately 74 cents to make.
