Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches. Which is an effective estimation strategy for finding the sum of the two lengths? Round 39.75 to 30 and 47.6 to 40, then add. Round 39.75 to 40 and 47.6 to 48, then add. Add 47.6 and 39.75, then round the answer. Subtract 39.75 from 47.6, then round the answer.

Answers

Answer 1

Answer:

Add 47.6 and 39.75, then round the answer

Step-by-step explanation:

If Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches, the effective strategy of finding the sum of the two lengths is to:

1) First is to add the two values together

47.6 + 39.75

= (47+0.6)+(39+0.75)

= (47+39)+(0.6+0.75)

= 86 + 1.35

= 87.35

2) Round up the answer to nearest whole number.

87.35 ≈ 87 (note that we couldn't round up to 88 because the values after the decimal point wasn't up to 5)

Option C is correct

Answer 2

Answer:

B. Round 39.75 to 40 and 47.6 to 48, then add.

Maya has a smart phone data plan that costs $50 per month that includes 2 GB of dat, but will charge extra $15 per GB over the included amount. How much would Maya have to pay in a month where she used 3 GB over a limit? How much would maya have to pay in a month where she used over by x GB?

Answers

Answer:

a. $65

b. $(50 + 15x)

Step-by-step explanation:

A. From the question, we are told that the first 2 GB of data costs $50 while the subsequent extra GB cost $15 per GB

so for 3 GB, the normal $50 is charged for the first 2 GB while an extra $15 is charged for the extra 1 GB

so, the total amount charged for 3 GB will be $50 + $15 = $65

B. Amount to be paid in a month where x GB is used over the normal

Firstly, she will pay the $50 , then for the extra she will be paying $15 * x = $15x

So the amount to be paid will be;

$50 + $15x = $(50 + 15x)

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]

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:

For the following square, find the value of x after that Find the length of each side of the square above. Be sure to label your answer and then Find the perimeter of the square above. Make sure to label your answer Please i need help fast or else im gonna fail my class please take this seriously.

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.

Answer:

[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.
