Answer:

Step-by-step explanation:

First turn them into improper fractions.

16 3/4 ----> 67/4

4 2/3 -----> 14/3

67/4÷14/3= ?

Now use keep, change, flip strategy

67/4×3/14= 201/56

Now simplify 3 33/56

Mr. Akika has 49 21 cent and 31 cent stamps all told. The stamps are worth $13.39. how many of each kind of stamps does he have?

Lana71 [14]

Mr Akika has 18 21-cent stamp and 31 31-cent stamp.

He has 49 21-cent and 31-cent stamps all told.

let

x = number of 21 cent stamp

y = number of 31 cent stamp

Therefore,

<h3>Total number of stamp:</h3>

x + y = 49

<h3>Total cost of stamp:</h3>

21x + 31y = 1339

Therefore,

x + y = 49

21x + 31y = 1339

21x + 21y = 1029

10y = 310

y = 310 / 10

y = 31

Therefore,

x = 49 - 31

x = 18

Therefore, Mr Akika has 18 21-cent stamp and 31 31-cent stamp.

I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per squ

kumpel [21]

Answer:

side of 6.124 ft and height of 3.674 ft

Step-by-step explanation:

Let's s be the side of the square base and h be the height of the rectangular box.

The base and the roof would have an area of $s^2$ and cost of

$4s^2 + 2s^2 = 6s^2$

The sides would have an area of 4sh and cost of 4sh*2.5 = 10sh

So the total cost for the material is

$6s^2 + 10sh = 450$

$10sh = 450 - 6s^2$

$h = 45/s - 0.6s$

The volume of the shed has the following formula

$V = s^2h = s^2(45/s - 0.6s) = 45s - 0.6s^3$

To find the maximum value for V, we can take its first derivative, and set it to 0

$\frac{dV}{ds} = 45 - 1.2s^2 = 0$

$1.2s^2 = 45$

$s^2 = 45 / 1.2 = 37.5$

$s = \sqrt{37.5} = 6.124 ft$

h = 45/s - 0.6s = 3.674 ft

Hey there!☺

$Answer:\boxed{16}$

$Explanation:$

$\frac{28}{7}\times4$

Start by simplifying 28/7:

$\frac{28}{7}=4$

Now multiply 4 by what we have left, which is 4:

$4\times4=16$

16 is your answer.

Hope this helps!☺
