The combined height of one for tree and one Pinetree is 21 m. The height of four for a tree stacked on top of each other is 24 m taller than one Pinetree. How tall are the types of trees that Logan genetically engineered?

Answers

Given :

The combined height of one for tree and one Pine tree is 21 m.

The height of four for a tree stacked on top of each other is 24 m taller than one Pine tree.

To Find :

How tall are the types of trees that Logan genetically engineered.

Solution :

Let, height of tree and pine tree is x and y.

So, x + y = 21 ...1)

4x - y = 24 ...2)

Putting value of y from equation 1 to equation 2, we get :

4x - ( 21 - x ) = 24

5x = 45

x = 9 m

y = 21 - x = 21 - 9 = 12

y = 12 m

Therefore, length of tree and pine tree is 9 m and 12 m.

Answer:

B (130°)

Step-by-step explanation:

Because the angles are adjacent that means:

m<ADE + m<CDA = m<CDE

Using this equation, we can find what m<ADE is:

m<ADE = m<CDE - m<CDA

m<ADE = 177° - 47°

m<ADE = 130° (B)

Hope this helps :)

Answer:

Step-by-step explanation:

CDE is 177, meaning it’s not a straight line so it’s 3 degrees from a perfect line so if CDA is 47 add the 3 degrees and see if CDE was a perfect line what answer would get you 180.

Micheal and Tracy are carpeting their family room that is 14 1/2 feet long and 12 1/4 feet wide. To find the amount of carpet needed micheal says to multiply 15 1/2 and 12 1/4 and Tracy says to multiply 12 1/4 and 15 1/2 . Who is right how much carpet is needed

Answers

Answer:

Area of carpet = 177.625 ft²

Step-by-step explanation:

Given:

Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft

Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft

Find:

Area of carpet

Computation:

Area of carpet = lb

Area of carpet = (14.5)(12.25)

Area of carpet = 177.625 ft²

Micheal estimation = 15.5 x 12.25 = 189.875

Tracy estimation = 12.25 x 15.5 = 189.875

Both wrong.
