Answer:

100, because 180 - 50 - 90 = 40

The vertical angles theorem is applied, so now angle DCE is 40

And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.

180 - 80 = 100 = Angle E.

Scott invests $1000 at a bank that offers 6% compounded annually. Write an equation to model the growth of the investment.

soldi70 [24.7K]

You can use A=P(1+(r/n))^(nt)
n=homany times it is compounded a year: 1 annually
t=time in years
r=rate: 6% or .06
A=Final Amount
P=principle amount

A=1000(1+(.06/1))^(1*t)

The fare for a taxi cab is $2.50 per passenger and $0.75 for each mile. A group of friends has $22.00

xeze [42]

For this case we have to:

x: Let the variable representing the number of people to travel in the group

y: Let the variable representing the number of miles traveled.

If friends only have $22 then we have the following inequality:

$2.50x + 0.75y \leq22$

Now, if there are three people in the group we have that $x = 3.$

$2.50 (3) + 0.75y \leq22\\7.5 + 0.75y \leq22\\0.75y \leq22-7.5\\0.75y \leq14.5\\y\leq \frac {14.5} {0.75}\\y\leq19.33$

The taxi can travel a maximum of 19.33 miles.

On the other hand, if the group wants to travel 10 miles then we have to y = 10.

$2.50x + 0.75 (10) \leq22\\2.50x + 7.5 \leq22\\2.50x \leq22-7.5\\2.50x \leq14.5\\x\leq \frac {14.5} {2.50}\\x \leq5.8$

Thus, they could travel a maximum of 5 people.

ANswer:

$2.50x + 0.75y \leq22$

Traveling 3 people, the taxi can travel a maximum of 19.33 miles

Traveling 10 miles, a maximum of 5 people can travel

Please please help solve and show how you got the answers I will mark brainliest

stira [4]

Answer:

Step-by-step explanation:

One

Sin(x) = 15/24 = 0.625

x = sin-1(0.625)

x = 38.68

Two

Cos(x) = 8/11

Cos(x) = .727

x = cos-1(.727)

x = 43.34

Three

Tan(x) = 20/37

Tan(x) = 0.5405

x = tan-1(0.5405)

x = 28.39

Four

Cos(x) = 18/23

Cos(x) = .7826

x = cos-1(0.7826)

x = 38.50
