Answers

Question is not very clear, however answers will reflect numbers seen(with some assumptions since some questions are not entirely complete)

Answer and explanation:

1. If a rectangle has an area of 35 meters and width of 78 meters, what is the length

Given that area of rectangle is length *width

Let's call length x

We have the equation

78*x=35

78x=35/78

x= 0.449

Therefore length =0.449 meters

2. Greg wants to divide a 712 yard long ribbon into pieces of 14 yard long each.

How many pieces can he make?

Let's assume the ribbon is a square then it's area is 712*712= 506944

To find number of 14 yard long pieces from the 712 yard long ribbon, we first find area for 14 yard long ribbons= 14*14= 196

number of 14 yard long pieces from the 712 yard long ribbon= 506944/196

= 2586.449 pieces

3. Olivia has 23 minutes an hour to write thank you notes. It takes her 12 minutes of an hour per thank you note. How many can she write?

Since it takes Olivia 12 minutes to write thank you notes but she has 23 minutes to write one, in one hour(1 hour =60minutes) she would be able to write

60 minutes /12 minutes = 5 thank you notes instead of

60 minutes /23 minutes= 2.609 or 2 thank you notes

4. Jim has 14 cups of nuts. How much of the recipe can he make?

If recipe requires 7 cups of nuts for instance, Jim would be able to make 14/7 = 2 of the recipe

It says, "Simplify the Expression. Assume x is a non zero. Your answer should only have positive exponents"
Expression: x^-10×x^6

Answers

Answer:

Step-by-step explanation:

1/(x^4) or x^-4

Answer:

[tex]\frac{1}{x^{4}}[/tex]; x ≠ 0

Or if thats wrong, just put 1/x^4

Step-by-step explanation:

Okay so heres how we solve this

Rewrite:

The "x is a non zero" is a very poorly written exception so I completely understand if you started racking your brain over that

[tex]x^{-10}*x^6[/tex] ;  x ≠ 0

Note; you can ignore the expression until you write the simplified answer.

1 - Multiply using rules of exponents

[tex]x^{-10} * x^6 = x^{(-10~+~6)} = x^{-4}[/tex]

2 - Get rid of the negative exponent by using rules of exponents

[tex]x^{-4} = \frac{1}{x^4}[/tex]

3 - Rewrite with it being simplified

1/(x^4); x ≠ 0

Solve -17 = x/-3 for x. x =

Answers

Answer:

x equals 51

Step-by-step explanation:

1. Do the inverse operation of x/-3 which is multipulcation.

2. Multiply -17 by -3 to get the answer of 51.

Finish the equation by saying that x = 51, or 51 = x.

Answer:

X=51

Step-by-step explanation:

You would have to multiply 17 by 3.

10x3=30

7x3=21

then you add 30 and 21 which equals 51

A golf ball is hit with an initial velocity of 80 ft/sec.Use the equation h(t)=80t-16t^2 where h(t) is the height of the object in feet and t is the time in seconds. How long will it take for the ball to hit the ground?

Answers

Answer:

The ball takes 5 seconds to hit the ground

Step-by-step explanation:

The equation to model the height of a golf ball in time t is:

[tex]h(t)=80t-16t^2[/tex]

There are two moments when the height is zero: At launch time and when it hits the ground. To find the last time, we equate:

[tex]80t-16t^2=0[/tex]

Factoring out t:

[tex]t(80-16t)=0[/tex]

It gives us two solutions:

t=0

[tex]80-16t=0[/tex]

Solving:

[tex]-16t=-80[/tex]

[tex]t=-80/(-16)=5[/tex]

t = 5 sec

Thus, the ball takes 5 seconds to hit the ground

The gross domestic product (GDP) of France is about $2.00 × 10 12 12 , and the GDP of Tuvalu is about $4.00 × 10 7 7 . How many times larger is the GDP of France than the GDP of Tuvalu?

Answers

Answer:

France's GDP is 50 000 times larger than Tuvalu's GDP.

Step-by-step explanation:

Given: Gross Domestic Product (GDP) of France = $2.0 x [tex]10^{12}[/tex]

            Gross Domestic Product (GDP) of Tuvalu = $4.0 x [tex]10^{7}[/tex]

To determine the number of times in which the GDP of France is greater than that of Tuvalu, divide the GDP of France by the GDP of Tuvalu.

[tex]\frac{2.0*10^{12} }{4.0*10^{7} }[/tex] = [tex]\frac{2000000000000}{40000000}[/tex]

           = [tex]\frac{200000}{4}[/tex]

           = 50000

Therefore, France's GDP is 50 000 times larger than Tuvalu's GDP.
