Answer 2

Answer:

San is using an industrial kitchen to bake several batches of his famous chocolate chip granola bars. He needs to weigh out 78 ounces of chocolate chips, plus or minus 2.5 ounces. Given the equation, |c-78|=2.5, find the minimum and maximum amount of c of chocolate chips that he can weigh out. Explain all steps and solve.

Answers

Step-by-step explanation:

given that San weighs out 78 ounces

given that the margin is 2.5 ounces.

and also given that the formula is

|c-78|=2.5

maximum

the maximum ounces is= 78+2.5

the maximum ounces is= 80.5 ounces

minimum

the maximum ounces is= 78-2.5

the maximum ounces is= 76.5 ounces

Simplify the expressions below by using the rules of exponents. A.2^4 B.3^0 C.4^6∙4^(-3) D.(2^3 )^2 Answer:

Answers

Answer:

The three rules that we have are:

[tex]x^a*x^b = x^{a + b}[/tex]

[tex]\frac{x^a}{x^b} = x^{a - b}[/tex]

[tex](x^a)^b = x^{a*b}[/tex]

Then let's solve the problems:

A) 2^4 = 2^(2*2) = (2^2)^2 = 4^2 = 16.

B) 3^0 = 3^(a - a) = 3^a/3^a = 1. (for any real number a)

From this we can conclude that the power 0 of any number is equal to 1.

C) 4^6*4^(-3) = 4^(6 - 3) = 4^3 = 64

D) (2^3)^2 = 2^(3*2) = 2^6 = 64

Answer:

b = 8√3 mm, a = 16 mm, x = 5 ft, y = 5√2 ft.

Step-by-step explanation:

With 30° 60° 90° triangles, one side will be a number, the other leg will be that number multiplied by √3, and the hypotenuse will be 2 times that original number.

So in this case:

The original leg's length is 8 mm. Side b will be that 8 times √3.

So, b = 8√3 mm.

Side a will be 8 times 2.

So, a = 16 mm.

With 45° 45° 90° triangles, the two legs will be the same length, and the hypotenuse will be that number times √2.

So in this case:

The original leg's length is 5 ft. Side x will be that same length.

So, x = 5 ft.

Side y will be 5 times √2.

So, y = 5√2 ft.

Answer:

b = 8√3 mm, a = 16 mm, x = 5 ft, y = 5√2 ft.

Step-by-step explanation:

With 30° 60° 90° triangles, one side will be a number, the other leg will be that number multiplied by √3, and the hypotenuse will be 2 times that original number.

So in this case:

The original leg's length is 8 mm. Side b will be that 8 times √3.

Side a will be 8 times 2.

So, a = 16 mm.

With 45° 45° 90° triangles, the two legs will be the same length, and the hypotenuse will be that number times √2.

So in this case:

The original leg's length is 5 ft. Side x will be that same length.

So, x = 5 ft.

Side y will be 5 times √2.

So, y = 5√2 ft.

Answers

Answer:

x = 9 ; 39 in. ; 156 in.

Step-by-step explanation:

Because it is a square, we know that all 4 sides are equal to each other.

This means we can take the two expressions and equal them to each other.

4x + 3 = 3(2x - 5)

4x + 3 = 6x - 15

-2x + 3 = -15

-2x = -18

x = 9

Now that we know the value of x, we can substitute it in to find the side length.

4(9) + 3

36 + 3

39 in.

Therefore, each side of the square is 39 in.

Finally, since we know all the side lengths are 39, we can find the perimeter by adding up all 4 side lengths.

p = 4(39) = 156 in.

Therefore, the perimeter of the square is 156 in.

For her birthday party, Tausha is preparing bags of treats to share with her friends. She has 18 candy bars and 12 packs of gum. Tausha wants to use all of her candy and gum. What is the greatest number of bags of treats that Tausha can make if each of the bags has the same number of candy bars and packs of gum in it? How many candy bars and how many packs of gum will be in each bag?

Answers

Answer:

Tausha can make maximum 6 bags that has the same number of candy bars and packs of gum in it.

Number of candy bars in each bag [tex]=3[/tex]

Number of packs of gum in each bag [tex]=2[/tex]

Step-by-step explanation:

Given:

Number of candy bars = 18

Number of packs of gum = 12

To find: the greatest number of bags of treats that Tausha can make if each of the bags has the same number of candy bars and packs of gum in it

and number of candy bars and packs of gum in each bag

Solution:

Take H.C.F of 18 and 12

[tex]18=2(3^2)\\12=2^2(3)[/tex]

So,

H.C.F of 18 and 12 is 2(3) = 6

Therefore,

Tausha can make maximum 6 bags that has the same number of candy bars and packs of gum in it.

Number of candy bars in each bag = [tex]\frac{18}{6}=3[/tex]

Number of packs of gum in each bag = [tex]\frac{12}{6}=2[/tex]
