What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?

JulijaS [17]

Answer:

0.571428571429 grams per cm³

Step-by-step explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

= (1÷3)×(5×7)×9

= 105 cm³

Then

The density = mass/volume

= 60÷105

= 0.571428571429

you are assigned 25 spelling words to master you memorize 60% of the words how many do you have left to memorize

Volgvan

2.5 is 10% of 25. 2.5 * 6 = 15 = 60%

25 - 15 = 10. You have 10 words left to memorize.

2 1/4 x2 1/4 in mixed number

maks197457 [2]

Answer:

$5 \frac{1}{16}$ is the answer.

Step-by-step explanation:

Given:

$2 \frac{1}{4} \times 2 \frac{1}{4}$

<u>Step 1: Converting the mixed fraction into fraction:</u>

Multiply 4 by 2 add 1 to the result.

<u></u> $2\frac{1}{4}$ = $\frac{4 \times 2+1}{4}$

= $\frac{8+1}{4}$

= $\frac{9}{4}$

<u>Step 2: Performing the multiplication using the fraction</u>

= > $\frac{9}{4} \times \frac{9}{4}$

=> $\frac{81}{16}$

<u>Step 3: Converting the product back to mixed fraction </u>

divide 81 by 16 and find the remainder

=> $quotient \frac{remainder}{divisor}$

Dividing 81 by 16 we get 5 as quotient and 1 as remainder

Thus the result in mixed fraction will be

=> $5 \frac{1}{16}$
