Step-by-step explanation:

14: The print and the canvas should have similar dimensions to one another.

Let x be the height of the canvas.

The print is 24 by 36, and the canvas is 12 by x.

24/36 = 12/x, x = 18.

Hence the canvas is 18 inches tall.

15: Ann's room is 10 by 12.5 while her sketch of the room is 8 by 10.

Since 10/12.5 = 8/10, it is a scale drawing. The scale factor is 1:0.8.

16: Both rectangles are similar to each other.

14/9 = x/4.5, therefore x = 7.

17: There is a similar relationship between Bill's height + shadow, and the tree's height + shadow.

Bill's height : Bill's shadow length

= Tree's height : Tree's shadow length

Let y be the height of the tree.

This means that 6:4 = y:16, so y = 24.

Hence the tree is 24 feet tall.

Answer:

14. 18 inches tall

Step-by-step explanation:

14. 24in wide = 12in wide

36in tall = 18in tall

So technically the relationship of 24 to 12 is dividing it by 2 so you would do the same for 36in tall wall.

Sorry I could only do one I’m lazy and in a rush but hope this helps!

Laws of exponents:<br>Squares and Square roots:<br><br>√9a¹⁶b³⁶

Nadusha1986 [10]

Step-by-step explanation:

Square root is equivalent to 1/2 power:

${(9 {a}^{16} {b}^{36} )}^{ \frac{1}{2} }$

Square root of 9 is 3. Multiply the exponents by 1/2 to get:

$3{a}^{8} {b}^{18}$

Algebra method 5+2b=13

Rus_ich [418]

Answer:

The solution to the algebra equation is 4.

Step-by-step explanation:

We are given the equation 5+2b=13. We need to isolate the variable.

First, use subtraction property of equality and subtract 5 from both sides of the equation.

Thus, 2b=8

Now, use division property of equality and divide both sides of the equation by 2.

All things put into consideration, the solution to the algebra equation is 4.

I hope this helped!!

Find the answer<br> 29°<br> 36°<br> 49°<br> 61°

Alla [95]

<h3>Answer: Choice A, 29 degrees</h3>

Central angle CBA is a right angle, so it is 90 degrees. This means the arc measure from A to C, following the shortest path on the curve, is 90 degrees. This is minor arc CA. A minor arc is one that is less than 180 degrees in measure.

We want to find the measure of minor arc DE. This is the last piece of the puzzle, so to speak, that forms the entire arc ACD. This arc is 180 degrees because AD is a diameter.

So,

(minor arc DE) + (minor arc EC) + (minor arc CA) = arc ACD

x + 61 + 90 = 180

x + 151 = 180

x + 151 - 151 = 180 - 151 .... subtract 151 from both sides

x = 29

Minor arc DE is 29 degrees.
