Answer:

An Angle is formed when two rays or two line segment meet at a point.

 1. ∠JWT

Draw Ray JW and WT.The intersection of these rays create an Angle which is ∠JWT.

2.∠NBQ

Draw Ray NB and BQ.The intersection of these rays create an Angle which is ∠NBQ.

(Help me) been try to solve for three days! !!!!!!!!!!!!!! does anybody knows this answer !!!!! please !!!!! -Circles very difficult for me thank you !!!

Answers

Given:
diameter = 12 ft

Area = π r²

r = radius. It is 1/2 of the diameter.
r = 12 ft / 2 = 6 ft.

Area = 3.14 * (6ft)²
A = 3.14 * 36ft²
A = 113.04 ft² or 113.0 ft² rounded to the nearest tenth.

Darnell's car used 8 gallons of gasoline to travel 340 miles. after a mechanic worked on the car, it used 7 gallons of gasoline to travel 350 miles. If the price of the gasoline was approximately $4.00 per gallon, how much lest to the nearst cent per mile, did it cost to run the car after the mechanic worked on it?

Answers

so, after the mechanic worked on it, it only does 7 gallons for 350miles, how many gallons will it be at that rate, for 340 miles then?

\bf \begin{array}{ccll}gallons&miles\n\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\n7&350\nx&340\end{array}\implies \cfrac{7}{x}=\cfrac{350}{340}\implies \cfrac{7\cdot 340}{350}=x\implies 6.8=x

well, each gallon is 4 bucks, for 6.8 gallons that'd be 6.8*4.

we already know that before the mechanic worked on it, it was doing 8gallons for the same 340 miles, and at 4 bucks a gallon that'd be 8*4.

how much is her savings?

\bf \stackrel{\stackrel{\textit{gallons cost}}{\textit{before being fixed}}}{(8\cdot 4)}\qquad -\qquad \stackrel{\stackrel{\textit{gallons cost}}{\textit{after it was fixed}}}{(6.8\cdot 4)}

How long does it take to double a $1,000 investment that pays 6.5% annual interest, compounded monthly?Which equation can you use to solve this problem?
To the nearest year, it will take about ___
years to double the original investment.

Answers

To the nearest year, it will take about 10.7 years to double the original investment.

How to solbve for the period it would take

In this case, the principal P is $1,000, the interest rate r is 6.5% or 0.065 (in decimal form), the number of times compounded per year n is 12 (compounded monthly), and we want to find the time t when the investment doubles, so A is $2,000.

2000 = 1000(1 + 0.065/12)^(12t)

2 = (1 + 0.065/12)^(12t)

ln(2) = 12t * ln(1 + 0.065/12)

t = ln(2) / (12 * ln(1 + 0.065/12))

t ≈ 10.7
