I have a 3 foot board that needs to be equally decided into 1/2 how many extra peices will I have

anygoal [31]

Answer:

No extra pieces.

Step-by-step explanation:

Given:

Total number of foot board = 3

Equally divided into = 1/2

Question asked:

How many extra pieces will I have = ?

Solution:

By dividing 3 by 1/2 we can find the extra pieces.

= $3\div\frac{1}{2}$

= $3\times\frac{2}{1}$

= $6$

Since, the remainder is zero, thus there is no any extra pieces I have.

In △ABC, m∠A=50∘, m∠B=60∘, and m∠C=70∘.

kiruha [24]

Given:

In $\Delta ABC, m\angle A=50^\circ, m\angle B=60^\circ$ and $m\angle C=70^\circ$ .

$\Delta ABC$ is rotated $90^\circ$ counterclockwise to $\Delta XYZ$ .

To find:

The measure of angle Z.

Solution:

We know that the rotation is a rigid transformation. It means the image and figure are congruent to each other.

$\Delta ABC$ is rotated $90^\circ$ counterclockwise to $\Delta XYZ$ . So, $\Delta ABC\cong \Delta XYZ$ .

$\angle C\cong \angle Z$ (CPCTC)

$m\angle C=m\angle Z$

$70^\circ=m\angle Z$

Therefore, the measure of angle Z is 70 degrees.

Solve for a. Round to the nearest tenth, if necessary.

zmey [24]

Answer:

Step-by-step explanation:

tanx=12/18

x=arctan(12/18)

tan(90-x)=12/(a+5)

tan(90-arctan(12/18)=12/(a+5)

a+5=12/tan(90-arctan(12/18))

a=12/tan(90-arctan(12/18))-5

a=3

3/5 divide by 5/9 please help

klemol [59]

First of all you flip around the last fraction:
5/9 to 9/5

Then you multiply the top and the bottom number:
3*9/5*5 = 27/25 = 1.08

Hope this helps! :)
