Three single-digit numbers multiply to make 504 Write the missing numbers

Tom [10]

<span>Find for the 3 single digit number that will be multiplied together to get the product 504.
=> n x n x n = 504 – where n are the single digits that we need to multiply.
504 / 2 = 252
504 / 3 = 168
504 / 4 = 126
504 / 5 = 100.8
504 / 6 = 84
504 / 7 = 72
504 / 8 =63
504 / 9 = 56
Now, let’s have 7 8 9 as 3 numbers to multiply to get 504 as product.
=> 7 x 8 x 9
=> 504

What happens when the two addends have opposite signs and the number with the larger magnitude (size) is positive?

zimovet [89]

Answer:

The smaller addend is subtracted from the bigger addend

Step-by-step explanation:

Represent the two numbers with a and b such that a > b

So, the mathematical representation will be

$+a + (-b)$

Open the bracket

$+a -b$

<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>

<em></em>

<em>Take for instance; a = 6 and b = 4</em>

<em>This gives</em>

<em></em> $+6 + (-4)$ <em></em>

<em></em>

<em>Open the bracket</em>

<em></em> $= +6 - 4$ <em></em>

<em></em> $= 2$ <em></em>

Helen has 48 cubic inches of clay to make a solid square right pyramid with a base edge measuring 6 inches. Which is the slant h

Nikitich [7]

Answer: 5 inches

Step-by-step explanation:

Given: Volume of clay = 48 cubic inches

If we make a solid square right pyramid with a base edge a= 6 inches.

Then its base area = $a^2=6^2=36\ inches^2$

we know that volume of square right pyramid= $\frac{1}{3}\times\ a^2h$

Therefore, volume of square right pyramid made by all of clay= $\frac{1}{3}\times\ a^2h$ =48 cubic inches

$\Rightarrow\frac{1}{3}\times\ (36)\times\ h=48\\\Rightarrow12h=48\\\Rightarrow\ h=4\ inches.....\text{[Divide 12 on both sides]}$

Now, slant height $l=\sqrt{(\frac{a}{2})^2+h^2}$

$\\\Rightarrow\ l=\sqrt{3^2+4^2}\\\Rightarrow\ l=\sqrt{9+16}\\\rightarrow\ l=\sqrt{25}\\\Rightarrow\ l=5$

The slant height of the pyramid if Helen uses all the clay=5 inches
