Answer:

14)

21√2

15)

Leg: 7√3

Hypotenuse: 14

Step-by-step explanation:

The hypotenuse is √2 as long as each leg. That means the leg is 42/√2. Simplified to make 21√2.

The hypotenuse is always twice as long as the shortest leg on a 30-60-90 triangle. The longer leg is √3 as long as the shortest side.

The local pet store surveyed 50 people about pets. Eleven of these people owned dogs, 13 owned cats, and 6 owned fish. One perso

siniylev [52]

Answer: 29

Step-by-step explanation:

Let S denotes the total number of people surveyed, A denotes the event of having dog , B denotes the event of having cats and C denotes the event of having fish.

Given : n(S)=50 ;n(A)=11 ; n(B) =13 and n(C)=6

Also, n(A∩B)=5 ; n(A∩C) = 2 and n(B∩C)=3 and n(A∩B∩C)=1

We know that,

$n(A\cup B\cup C)=n(A)+n(B)+n(C)-n(A \cap B)-n(A \cap C)-n(B \cap C)-n(A \cap B\cap C)\\\\=11+13+6-5-2-3+1=21$

Now, the number of people owned none of these pets :-

$n(S)-n(A\cup B\cup C)\\\\=50-21=29$

Hence, the number of people owned none of these pets =29

What is the answer 2p-a=3p+b if p is the subject of the formula

djverab [1.8K]

<em>*To solve for a variable, you have to isolate the desired variable onto 1 side</em>

So firstly, subtract 2p on both sides of the equation: $-a=p+b$

Next, subtract b on both sides of the equation, and <u>your answer will be $-a-b=p$ </u>

$l=2 \pi r$
r=0.25 miles
l=2× $\pi$ ×0.25
=0.5 × 3.14
=1.57

120(minutes)÷2(miles)=60(minutes per mile)
60×1.57=94.2 minutes
