3. The length of the hypotenuse of a right triangle is 12 yards. Theother two sides are equal in length. Find the length of each side to the
nearest tenth of a yard.

Answers

Answer 1
Answer:

Answer: The other two sides measure 8.5 yards each

Step-by-step explanation: The triangle is a right angled triangle with the other two sides of equal measurement. What this means is that, one angle measures 90 degrees and the other two angles would be of equal measurement. The reason being that we have an isosceles triangle and one property of an isosceles triangle is that two sides are equal and two angles are equal. If one angle measures 90, then the other two would be measured as

(180 - 90)/2 and this equals

90/2 and that equals 45 degrees each. To calculate the length of the equal sides, we use the trigonometric ratio of sine.

(Let one of the unknown sides be A)

Sin 45 = opposite/hypotenuse

Sin 45 = A/12

By cross multiplication we now have

Sin 45 x 12 = A

0.7071 x 12 =A

8.4852 = A

To the nearest tenth

A = 8.5 yards

This means the other equal side would measure 8.5 yards as well.

9x1x5= & I have to use parentheses

Answers


(9 x1) x 5 =  9 x 5 = 45

9 x (1 x 5) = 5 x 9 = 45

So it doesn't matter where the parentheses were suppose to go as you can see I worked it both ways and the answer is the same.

Hope this helps you. :-) 
You can place the parentheses anywhere cause if you do (9x1)5 it will equal 45. And if you do (5x1)9 it will also be 45. So where ever you put it , it will equal the same amount. But, jus in case next time asked your teacher or friends for further help.

Multistep Sandy charges each family that she babysits a flat fee of $10 for the night and an extra $5 per child.kimmi charges $25 per night no matter how many children a family has write a equation that compare the two girls also is the fees are the same how many children a family have to have in order to be the same

Answers

Step-by-step explanation:

Consider the provided information.

Sandy charges each family that she babysits a flat fee of $10 for the night and an extra $5 per child.

Let x is the number of child, Sandy charges fixed fee of $10 and $5 for each child. Thus, the charges for one night is:

10+5x

Kimmi charges $25 per night no matter how many children a family has. Thus, the charges for one night is:

25

Now we need to write an equation that would compare the two girls charges:

10+5x=25

Thus, the required equation is10+5x=25.

Now we need to find how many children a family have in order to be the same charges.

For the same charges solve the equation as shown:

10+5x=25

5x=15

x=3

So, the number of children has to be 3 for same charge.
n= night c= child
sandy= $10+$5c
kimmi= $25n
if sandy babysits 3 children for one night they will both be the same price
sandy= $10+5(3)=$25
kimmi= $25

using the Pythagorean theorem we can tell if it is a right triangle.
 the formula is a^2 + b^2 = c^2
a =9
b =12
c=15

9^2 + 12^2 = 81 + 144 = 225

15^2 = 225

225 = 225 so it is a right triangle

 the answer is TRUE
if right triangle then c^2 = a^2 + b^2

c^2 = 25^2 = 625
a^2 + b^2 = 9^2 + 12^2 = 81 + 144 = 225

SO
c^2 = a^2 + b^2
225 = 225
