What is 64 scaled down by a factor of 1/10

Mnenie [13.5K]

Very interesting wording but from what I gathered, scaling down by a factor of 1/10 would be 64- 6.4(1/10 of 64) so your final answer would be 57.6

Hope this explanation helps ;)

The base of a box is a rectangle. The width of the box is half its length. The height of the box is 0.5m. Find the volume of the

Ivan

Let x be the length and y be the width.
We know already
$y= \frac{x}{2}$
Area of the base $xy$
Area of the sides: $(x+y)0.25$
We get the equation $xy=0.25(x+y)-1.08$
We will solve the system:
$y= \frac{x}{2}\\xy=0.5(x+y)-1.08$
The above system has no real solution, please check your values.

Use the FOIL Method to find (x−4)(x+8).

Answer:

$x^2 +4x - 32$

Step-by-step explanation:

By FOIL method, $(x-4)(x+8) = x \cdot x + x \cdot 8 + -4 \cdot x + -4 \cdot 8 = x^2 +4x - 32.$

The sequence an = 8, 13, 18, 23, ... is the same as the sequence a1 = 8, an = an-1 + 5.

harkovskaia [24]

Actually, this answer would be true. Why?

The first equation is: a(sub n) = 8, 13, 18, 23

The second is: a(sub 1)=8 ; a(sub n)= a(sub n-1)+5
if you wish to find the second term, plug two into the equation for n
8+5=13
to find the third, plug the second term, 13, in for n.
13+5=18.

Hope this helped! I know it's a bit on the late side, but at least you can get the general idea!
