Diego props a 10ft ladder against the wall how high up will the ladder reach if the foot of ladder is 5 feet away from the wall ?

Answer:

Step-by-step explanation:

If we connect points C and C' with the center of rotation P, the angle CPC' appears greater than 90°, so the angle could be 105° or - 105°

Since the rotation is counterclockwise the angle of rotation is deemed as positive.

Correct choice is D.

Answer:

2960

Step-by-step explanation:

360 x 20 = 7200

212 x 20 = 4240

7200-4240 = 2960

You calculate wall-length like this.

Measure the length of each wall including doors and windows. Find the total square feet of the wall(s) by multiplying ceiling height by total wall length. Subtract areas that will not be covered.

Answer: The answer is 26.

Step-by-step explanation:

Simple, find the unit rate. That's 19.5 / 0.75 = 26.

or using fractions:

19 2/4  divided by 3/4

78/4 divided by 3/4

78 / 3 = 26

4 / 4 =    1

Unit rate = 26books/1 hour

Answer:

24 unit

Step-by-step explanation:

From the question,

JK = 2×NK.................... Equation 1

Using pythagoras theorem,

a² = b²+ c²................. Equation 2

From the diagram,

a = 15 unit, b = 9 unit, and c = NK

Substitute these values into equation 2

15² = 9²+(NK)²

Solve for NK

225 = 81+(NK)²

(NK)² = 225-81

(NK)²  = 144

NK = [tex]\sqrt{144}[/tex]

NK = 12 unit.

Substitute these value of NK into equation 1

JK = 2×12

JK = 24 Unit.

Answer: [tex]6, 9\ \text{units}[/tex]

Step-by-step explanation:

Given

The Sum of length and width is [tex]15\ units[/tex]

length is 3 units more than the width

width is [tex]x[/tex]

length is [tex]x+3[/tex]

Their sum is 15

[tex]\Rightarrow x+x+3=15\\\Rightarrow 2x=12\\\Rightarrow x=6\ \text{units}[/tex]

Length is [tex]x+3=9\ \text{units}[/tex]

Width is  [tex]x=6\ \text{units}[/tex]

Answer:

1/3 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

26 - 26 = 0

180 - 26 = 154

x = 154°

The value of the x will be 154°.

The central angle and the angle between the tangents are supplementary.

If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to line L.

So,

x + 26° = 180°

Subtract 26° from both sides;

x + 26 - 26 =  180 - 26

x = 154°

Hence, the value of the x will be 154°.

Answer:

the answer is 221.1

Step-by-step explanation:

The volume of the rectangular prism is 221.1 in³.

The volume of any object defined the capacity of it, how much it can hold something is called its volume.

Given is rectangular prism, we need to find the volume of the same,

So, we know that the volume of a rectangular prism is the product of its dimensions.

V = length × width × height.

[tex]V = 16\frac{3}{4} \times 4\frac{2}{5} \times 3[/tex]

[tex]V = \frac{67}{4} \times \frac{22}{5} \times 3[/tex]

V = 4422/20

V = 221.1

Hence, the volume of the rectangular prism is 221.1 in³.

Answer:

101.25 seconds.

Step-by-step explanation:

We know that Ed solved the puzzle 3/4 faster than Brett.

Then if Brett solved the puzzle in a time T, Ed solved the puzzle in a time (3/4)*T.

We know that Brett solved the puzzle in 135 seconds, then:

T = 135s

This means that Ed solved the puzzle in:

time = (3/4)*T = (3/4)*135s = 101.25 seconds.

Answer:

Number of $1 coins are 25 and number of 50 cent coins are 30.

Step-by-step explanation:

Let's set up the equations.

Let there are x number of $1 coins

There are y number of 50 cent coins

So, x+y =55

1 x+0.50 y =40

Solve the equations for x and y.

Solve the first equation for y.

y=55-x

Substitute y as 55-x into the second equation.

1 x+0.50(55-x)=40

Solve the equation for 'x'.

Distribute the 0.50 to get rid the ( ).

1 x+27.5-0.50 x= 40

Combine like terms

0.50 x +27.5=40

Subtract both sides 27.5

0.50 x =12.5

Divide both sides by 0.50

x=25

Now, plug in x as 25

y=55-25

y=30

So, number of $1 coins are 25 and number of 50 cent coins are 30.
