Answer:

Technically, 42×2=84

Step-by-step explanation:

You could do this by adding 42+42=84

Multiplying 2 times the 2 and the 4, which gives you 84.

If you wanted the factoring then:

2 is a prime number

42 could be like 42

/ \

21 2

/ \

but I dont really know how factoring would help you multiply. I hope this helps

There are 22 animals in the barn. Some are geese and some are goats. There are 82 legs in all. How many of each animal are there

Free_Kalibri [48]

Let the number of geese be x.

Then number of goats is 22-x.

A goose has 2 legs, and a goat has 4.

There are a total of 82 legs.

So,

2x + 4(22-x) = 82

2x + 88 - 4x = 82

-2x = -6

x = 3

There are 3 geese and (22-3=) 19 goats.

Answer:

The coordinates of E are $E(x,y) = \left(\frac{9}{2}, 0 \right)$ .

Step-by-step explanation:

The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.

Vectorially speaking, dilation is defined by the following operation:

$P'(x,y) = O(x,y) + k\cdot [P(x,y) - O(x,y)]$ (1)

Where:

$O(x,y)$ - Point of reference.

$P(x,y)$ - Original point.

$P'(x,y)$ - Dilated point.

$k$ - Dilation factor.

By applying this operation, point B becomes point D:

$B(x,y) = (0,4)$ , $D(x,y) = (0,6)$

$D(x,y) = (0,0) + k\cdot [(0,4)- (0,0)]$

$D(x,y) = (0,0) + k\cdot (0,4)$

$(0,6) = (0,0) +(0,4\cdot k)$

$(0, 6) = (0,4\cdot k)$

$k = \frac{3}{2}$

Lastly, we transform point C into point E by applying the same operation: $C(x,y) = (3, 0)$ , $O(x,y) = (0,0)$ and $k = \frac{3}{2}$

$E(x,y) = (0,0) + \frac{3}{2}\cdot [(3,0)-(0,0)]$

$E(x,y) = \left(\frac{9}{2}, 0 \right)$

The coordinates of E are $E(x,y) = \left(\frac{9}{2}, 0 \right)$ .

A cube with a volume of 64 cubic meters is scaled by a factor of .5 what is the volume of the modified cube in cubic meters/7472

oksano4ka [1.4K]

To be honest I am not sure but maybe 32 because that is half or 96 but I was never really good with scales.

It takes a turtle 3 ¼ hours to walk 1 ½ miles. How many hours does it take to walk one mile?

Norma-Jean [14]

Answer:

It will take 6/13 hours to walk one mile

Step-by-step explanation:

Here, we want to calculate the number of hours it take to walk one mile

From the question, 1 1/2 miles take 3 1/4 hours

the number of hours it will take to walk 1 mile will be;

1 1/2 divided by 3 1/4

= 3/2 divided by 13/4

= 3/2 * 4/13 = 6/13 hours

27/125 in simplest form

WINSTONCH [101]

$\frac{27}{125}$

It is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
