Which interval on the graph indicates she is stuck in a traffic jam? A B C D

masha68 [24]

Let's look at each one of the intervals.

Interval A
Interval A looks like she's going at a pretty steady pace, so Interval A is not the correct answer.

Interval B
Interval B looks like she stays at 2.5 for an hour. That looks like a traffic jam to me!

The correct answer is Interval B.

Hope this helps! If it does, be sure to rate, thank and if it really helped, give brainliest. It helps me rank up. Thanks! :)

If the diameter of circle a measures half of the diameter of circle b, then the area of circle b is how many times the area of c

Eduardwww [97]

Circle b:

Diameter = x

Radius = $\frac{x}{2}$

Area = $\pi r^{2} = \pi ( \frac{x}{2} )^{2} = \frac{ \pi x^{2} }{4}$

Circle a:

Diameter = $\frac{x}{2}$

Radius = $\frac{x}{2} * \frac{1}{2} = \frac{x}{4}$

Area = $\pi r^{2} = \pi ( \frac{x}{4} )^{2} = \frac{ \pi x^{2} }{16}$

Thus,

Area of circle b to area of circle a

= $\frac{ \pi x^{2} }{4}$ ÷ $\frac{ \pi x^{2} }{16}$

= $\frac{ \pi x^{2} }{4}$ × $\frac{ 16 }{\pi x^{2}}$

= 4

Hence, the area of circle b is 4 times the area of circle a.

Leah is financing $340,000 to purchase a house. How much money will she save over the life of a 30-year, fixed-rate loan by buyi

Stells [14]

Answer:

$38250

Step-by-step explanation:

Given data

P= $340,000

t= 30-year,

r1= 6.475%

r2= 6.85%

For r1

A= P(1+rt)

A= 340,000(1+0.06475*30)

A= 340,000(1+1.9425)

A= 340,000*2.9425

A= $1000450

For r2

A= P(1+rt)

A= 340,000(1+0.0685*30)

A= 340,000(1+2.055)

A= 340,000*3.055

A= $1038700

The difference is '

= 1038700-1000450

=$38250
