what is the distance between 8 1/2 and 4 1/2?

Answers

Answer 1

Answer:

4

Step-by-step explanation:

just subtract 4.5 from 8.5

Answer 2

A fraction is a way to describe a part of a whole. The distance between 8 1/2 and 4 1/2 is 13 feet.

What is a Mixed Fraction?

A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator. A mixed fraction can be converted as,

2 1/2 = (2×2 + 1)/2

= 5/2

= 2.5

Now, the distance between them

Distance = (8 1/2) feet + (4 1/2) feet

Converting Mixed fractions to fractions,

(8×2 + 1)/2  +  (4×2 + 1)/2

= 17/2 + 9/2

= (17+9)/2

= 26/2

= 13 feets

Hence, the distance between 8 1/2 and 4 1/2 is 13 feet.

Robert and his younger sister are selling gift wrap to raise funds for the middle school band. Robert's sales are 2.5 times his sister's sales. Their total sales together can be represented by the equation x+2.5x= 63 . Which of these statements are true? Choose ALL that are correct. A. Robert's sales are represented by x when solving 3.5x= 63 . B. Robert's sister's sales total $18.00. C. Robert's sales total $25.20. D. Robert's sister's sales are represented by x when solving 3.5x= 63 . E. Robert's sales are represented by x when solving 2.6x= 63 .

Answers

Answer:

The answer is B. and D.

Step-by-step explanation:

if you solve the equation, you will find that X=18. Since his sister's sales are X, his sister sold 18. You multiply by 2.5 to find Robert's sales.

The correct statements are (B) and (D).

What is an equation?

Two or more expressions with an equal sign are defined as an equation.

The given equation is x + 2.5x = 63.

Note that Robert's sales are 2.5 times his sister's sales, therefore, if his sister's sales is x then his sales are 2.5x

Hence, option (A) is incorrect, as Robert's sales are 2.5x.

Solve the equation as follows:

x + 2.5x = 63

3.5x = 63

x = 63/3.5

x = 18

Hence, option (B) is correct.

Since x=18, Robert's sales are:

2.5 × 18

= 45

Hence, option (C) is incorrect, as Robert's sales are $45, not $25.20.

Option (D) is already shown to be correct.

Option (E) is also incorrect, as option (D) is correct.

Hence, the correct statements are (B) and (D).

How I got D:

-2 3/4 can be turned into -2.75 by dividing 3/4.

-2 3/4 is the smallest number out of all of them so it has to be first.

-2.67 is the second smallest value.

3/5 is .60 making it the third smallest value.

4 is the second largest value.

17/4 is 4.25, which is the largest.

The table above gives selected values of twice-differentiable functions f and g, as well as the first two derivatives of g. If f′ (x)=3 for all values of x, what is the value of [tex]\begin{equation}\int_{2}^{4} f(x) g^{\prime \prime}(x) d x\end{equation}[/tex]

Answers

Answer:

63

Step-by-step explanation:

∫₂⁴ f(x) g"(x) dx

Integrate by parts.

If u = f(x), then du = f'(x) dx.

If dv = g"(x) dx, then v = g'(x).

∫ u dv = uv − ∫ v du

= f(x) g'(x) − ∫ g'(x) f'(x) dx

f'(x) is constant at 3, so:

= f(x) g'(x) − ∫ 3 g'(x) dx

= f(x) g'(x) − 3 g(x)

Evaluate from x=2 to x=4.

[f(4) g'(4) − 3 g(4)] − [f(2) g'(2) − 3 g(2)]

[(13) (7) − 3 (9)] − [(7) (1) − 3 (2)]

64 − 1

63

The required value of [tex]\int\limits^4_2 {f(x)g"(x)} \, dx (1)[/tex] is 63.

Given that,

The table above gives selected values of twice-differentiable functions f and g,

The first two derivatives of g. If f′ (x) = 3 for all values of x.

We have to determine,

What is the value of [tex]\int\limits^4_2 {f(x)g"(x)} \, dx (1)[/tex].

According to the question,

To obtain the value of given function, integrating the function,

[tex]= \int\limits^4_2 {f(x)g"(x)} \, dx (1)[/tex]

Integrating by using by-parts.

[tex]= \int\limits^4_2 {f(x)g"(x)} \, dx (1)\\\\if\ u = f(x), \ then \ du = f'(x)dx\\\\if \ dv = g"(x)dx, \ then \ v = g'(x)\\\\[/tex]

Then,

[tex]\int u\ dv = uv\ - \ \int v \ du\\\\= f(x) \ g'(x) - \int g'(x) f'(x) \ dx\\[/tex]

if f'(x) is constant at 3,

Then,

[tex]= f(x) g'(x) - \int g'(x)\dx\\\\= f(x) g'(x) -3g(x)[/tex]

Substitute from x = 2 to x = 4 then evaluate,

[tex]= [f(4)\ g'(4) - 3 \ g (4)]- [f(2)\ g'(2) - 3 \ g (2)]\\\\= [(13).(7) - 3.(9)] - [7.(1)- 3.(2)]\\\\= [91-27} - {7-6}\\\\= 64-1\\\\= 63[/tex]

Hence, The required value of [tex]\int\limits^4_2 {f(x)g"(x)} \, dx (1)[/tex] is 63.

A crate to ship boxes of baseballs can hold 4 boxes that are each (6 x 6) * 2. How
many baseballs can be shipped in the crate, if each baseball takes a 1x1x I space?
Show your thinking using words, numbers, or labeled sketches.

Answers

Answer:

Each crate can contain 288 baseballs.

Step-by-step explanation:

Since one baseball takes up 1 × 1 × 1 space, and each box has 6 × 6 × 2 units of space, then the number of baseballs in one box is 6 × 6 × 2 ÷ 1 × 1 × 1 = 72 baseballs.

So, 72 baseballs can be contained in one box.

Now, since each crate contains 4 boxes, the number of balls contained in each crate is 1 × 4 boxes = 1 × 4 × 72 baseballs = 288 baseballs.

So each crate can contain 288 baseballs.
