Find the value of the expression:<br><br><br><br> 56 ÷ 7 + 7 × 3

miv72 [106K]

First, you have to apply the order of operations.

Division and multiplication come first here and they go from left to right. So,

56/7 = 8
7*3 = 21
Then, the addition.
8 + 21 = 29.

So the value of your expression is 29.

A scale drawing of a square has a side length of 6 millimeters. The drawing has a scale of 1 mm : 7 km. Find the actual perimete

zvonat [6]

Answer:

The real perimeter is:

$P= 24 mm *\frac{7 km}{1mm}= 168 km$

And the area would be:

$P = 36mm^2 *\frac{(7km)^2}{(1mm)^2} = 1764 km^2$

Step-by-step explanation:

For this case we know one side of a square given 6mm.

We can begin calculating the perimeter for the scale figure with this formula:

$P = 4x = 4*6 mm =24 mm$

The area for this case is given by:

$A = x^2 = 6mm^2 = 36 mm^2$

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

$P= 24 mm *\frac{7 km}{1mm}= 168 km$

And the area would be:

$P = 36mm^2 *\frac{(7km)^2}{(1mm)^2} = 1764 km^2$

Simplify (5^-2)^4 Please Help i don’t understand

Maslowich

Answer:

5^ -8 or 1/ 5^8

Step-by-step explanation:

(5^-2)^4

We know that a^b^c = a^(b*c)

(5^-2)^4 = 5^(-2*4) = 5^(-8)

We know that a^ - b = 1/ a^b

5^ -8 = 1/ 5^8
