The bottom of a 20-foot ladder is placed 4 ½ feet from the base of a house. To the nearest foot, at what height does the ladder
Oksanka [162]

Answer: 19 ft

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:

c^2 = a^2 + b^2

Where c is the hypotenuse of the triangle (in this case the length of the ladder) and a and b are the other sides.

Replacing with the values given:

20^2 = (4 1/2)^2 + x^2

400=20.25 + x ^2

400-20.25 = x^2

379.75 = x^2

√379.75 = x

x = 19.48

x= 19 ft

Feel free to ask for more if needed or if you did not understand something.

Jarrett's puppy weighed 3 3/4 ounces at Birth. At 1 week old, the puppy weighed 5 1/8 ounces. At 2 weeks old, the puppy weighed
Ad libitum [116K]

Answer:  The answer is 7\dfrac{7}{8} ounces.

Step-by-step explanation: Given in the question the weight of Jarrett's puppy at birth, one week old and 2 weeks old are as follows:

b_0=3\dfrac{3}{4}=\dfrac{15}{4}~\textup{ounces},\\\\\\b_1=5\dfrac{1}{8}=\dfrac{41}{8}~\textup{ounces},\\\\\\b_3=6\dfrac{1}{2}=\dfrac{13}{2}~\textup{ounces}.

We can see that

b_1-b_0=b_2-b_1=\dfrac{11}{8}.

So, the weight of the baby will make an arithmetic progression with first term 'a' and common difference 'd' as follows:

b_0=\dfrac{15}{4},~~d=\dfrac{11}{8}.

Thus, the weight of the puupy after 3 weeks will be

b_3=b_0+3\times d=\dfrac{15}{4}+3\times\dfrac{11}{8}=\dfrac{30+33}{8}=\dfrac{63}{8}=7\dfrac{7}{8}~\textup{ounces}.

What is the value of x? geometry
Tpy6a [65]

Answer:

x = 35°

Step-by-step explanation:

A straight line = 180

180 - 95 = 85

The triangle has 180 degrees.

60 + 85 = 145

180 - 145 = 35

x = 35°
