Answer:

The ladder is 11 m long approximately .

Step-by-step explanation:

Given :The foot of a ladder is placed 7 meters from a wall.

To Find :If the top of the ladder rests 9 meters up on the wall, how long is the ladder?

Solution :

The foot of a ladder is placed 7 meters from a wall.

Base = 7 m

The top of the ladder rests 9 meters up on the wall

So, height at which ladder touches wall i.e. perpendicular = 9 m

We are supposed to find how long is the ladder i.e. Hypotenuse

Hypotenuse^2 = Perpendicular^2 +Base^2

Hypotenuse^2 =9^2 +7^2

Hypotenuse =\sqrt{9^2 +7^2}

Hypotenuse =11.40175

Hence The ladder is 11 m long approximately .

We can find the length of the ladder by squaring the known digits, adding them, and finding the square root of the sum. This would mean our first equation, after squaring, will look like this:

49+81=130

Now that we have <em>c</em> squared, we can go through and find the approximate square root, which is 11.4. That would mean the ladder is 11.4 meters long.

An angle made with two radii whose vertex is at the center of a circle is the definition of what
Katena32 [7]

Answer: congruent central angles

Step-by-step explanation:

A central angle is an angle formed by two radii with the vertex at the center of the circle. In the diagram at the right, ∠AOB is a central angle with an intercepted minor arc from A to B. In a circle, or congruent circles, congruent central angles have congruent arcs.

Mary has 60 candy pieces and 45 chocolates. She wants to distribute the candy to her little sister's friends at her birthday par
Anna11 [10]

Answer:

5 friends

Step-by-step explanation:

Candy pieces = 60

Chocolate = 45

What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over?

To calculate this, find the lowest factor of 60 and 45

60:

Factors = 2, 4, 5, 6,

45:

Factors= 3, 5, 9

The lowest common factor of 60 and 45 is 5

The smallest number of her sister's friend so each person get an equal number of candy pieces and chocolate so there won't be any leftover is 5

That is

If there are 5 friends at the birthday party

60 candy pieces among 5 friends

= 60/5

= 12 pieces each

45 chocolate among 5 friends

= 45/5

= 9 each

The lines shown below are parallel.if the green line has a slope of -1,what is the slope of the red line?
vova2212 [387]

Answer:

-1

Step-by-step explanation:

If a line is parallel on a graph, then that means that they will descend/climb at the same rate. Therefore, the slope of this line is also -1.

Hope this helped!

The minimum point on the graph of the equation y = f(x) is (-1, -3). What is the minimum point
vladimir1956 [14]

Answer:

(4, -3)

Step-by-step explanation:

the equation f(x-5) is a translation of the equation f(x) by 5 units to the right.

So, if all points of the equation f(x) are shifted 5 units to the right, the minimum point of the graph is also shifted 5 units to the right, so to find the minimum point of y = f(x - 5), we just need to sum 5 units to the x-coordinate:

Minimum point = (-1 + 5, -3) = (4, -3)

So the minimum point of y = f(x - 5) is (4, -3).
