Please help me as soon as possible, it would be great if you gave me an explanation!

Answers

For number 20:

Because a triangle is 180 degrees, we will equal all the angles we know to that. So, this is how we will write our equation:

Solve for x:

60 + x + 20 + 3x = 180

4x = 100

x = 20

Using 75, you can find the angle measure by plugging 75 where x is present in the angle measures. For example:

x = 20,

20 + 20 = 40

3(20) = 60

For number 21:

The shape shown is basically two triangles, so 180 x 2 is 360. Again, same procedure. Add all known angle measures and make an equation where they all equal 360.

Solve for x:

x-5+x+35+1.4x+x=360

x = 75

By isolating x, you should get an answer of 75. Now, plug that into each of the equations:

x = 75

75 + 35 = 110

75 - 5 = 70

1.4(75) = 105

At a little-known vacation spot, taxi fares are a bargain. A 12-mile taxi ride takes 18 minutes and costs $7.20. You want to find the cost of a 46-mile taxi ride. What unit price do you need?

Answers

Answer:

unit cost in dollars per mile

Step-by-step explanation:

You are given cost, miles, and time for a certain trip.

You are asked the cost for a certain number of miles, so you need a unit cost of dollars per mile.

$7.20/(12 miles) = $0.60/mile

$0.60/mile * 46 miles = $27.60

By first finding the unit cost per mile, you can then find the cost of the 46-mile trip.

Answer:

0.40, mile

Step-by-step explanation:

because you had to multiply to get the total cost and then divide the number by the total cost.

Step-by-step explanation:

A person places $4760 in an investment account earning an annual rate of 1.6%, compounded continuously. Using the formula V=PertV = Pe^{rt}V=Pert, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 7 years.

Answers

Answer:

$5324.12

Step-by-step explanation:

Given that the principal p= $4760

rate r= 1.6% 1.6/100 =0.016

time t= 7years

by applying the expression

[tex]V = Pe^{rt}[/tex]

We have

[tex]V = 4760e^{0.016*7}\\\\ V=4760e^{0.112}\\\\ V=4760*1.11851286065\\\\ V=$5324.12[/tex]

Hence after 7 years the money in the account will be $5324.12

Essentially, find the growth rate and divide the larger number by that number, or if you were given the smaller number (15), you would simply need to multiply 15 by 4 to find 60.

What is the slope of 12x + 3y =7

Answers

X=7/12-y/4

Ik this because I did it

Answer: y = -4x + 7/3 so the slope is -4

Step-by-step explanation:

First, we need to put the linear equation into the slope-intercept form: y = mx + b

We do this by subtracting 12x from both sides, so the equation now looks like 3y = -12x + 7. Now we divide both sides by 3 to get y alone, which gives us y = -4x + 7/3

m is always the slope, so the slope of this line is -4 or -4/1.

times what the other person pays. If the rent
is $850, how much will each friend pay?

Answers

Answer:

Friend A pays $340 and friend B pays $510

Step-by-step explanation:

Let's call

x: payment of friend A

1.5x: payment of friend B

The sum of both payments must total $850, thus:

x + 1.5x = 850

Simplifying:

2.5x=850

x = 340

Now for friend B:

1.5x=1.5*340=510

Friend A pays $340 and friend B pays $510
