what is angle a and c if b is 63 degrees? You will get 100 points for answering please help

Answers

Answer 1

Answer:

Angle A measures 76°

Step-by-step explanation:

The three interior angles of a triangle will always equal 180. Therefore:

[tex](63)+(x+7)+(2x+8)=180[/tex]

Solve for x. Add and combine like terms:

[tex]78+3x=180[/tex]

Subtract 78 from both sides:

[tex]3x=102[/tex]

Divide both sides by 3. So, the value of x is:

[tex]x=34[/tex]

Angle A is given by:

[tex]m\angle A=2x+8[/tex]

Since we know that x = 38:

[tex]m\angle A=2(34)+8=76[/tex]

Angle A measures 76°

Hi! Could you help me me out and solve these two problems? "eight less than the product of seven and xxx", and "the sum of six and the product of three and d". Thank you!

Answers

Given:

The given statement are:

a. Eight less than the product of seven and x.

b. The sum of six and the product of three and d.

To find:

The expression for the given statements.

Solution:

Product of 7 and x is 7×x = 7x.

Eight less than the product of seven and x is 7x - 8.

Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.

Product of 3 and d is 3×d = 3d.

The sum of six and the product of three and d is 6+3d.

Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.

Answer:

x = 14.5

Step-by-step explanation:

The diagonals of a rhombus are at right angle to each other, then

∠ BOA = 90° , so

6x + 3 = 90 ( subtract 3 from both sides )

6x = 87 ( divide both sides by 6 )

x = 14.5

Anna opened a savings account and deposited $300.00 as principal. The account earns 1%
interest, compounded annually. What is the balance after 2 years?

Answers

Answer:

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1%/100 = 0.01 per year,

then, solving our equation

I = 300 × 0.01 × 2 = 6

I = $ 6.00

The simple interest accumulated

on a principal of $ 300.00

at a rate of 1% per year

for 2 years is $ 6.00.

Times 300 by the 1%, in this case 0.01. Then add that amount to 300. Hope that helps.

1. Bill decided to buy six books on history instead

of four books on politics. It follows, then, that

the opportunity cost of each history book was ______

books on politics.

Answers

Answer: 2/3 books on politics

Step-by-step explanation:

The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.

Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.

= Number of politics books / Number of history books

= 4 / 6

= 2/3 books on politics

Bill gave up 2/3 books on politics to get a single history book.

You often go to school by bus. You have two bus systems you could take. City Bus offers a monthly pass that costs $15 and then you pay $1 per ride. Campus Transport simply charges $2.50 per ride and does not require a monthly pass. After how many rides will the total costs of the two options be the same? Write a system of equations in order to solve this problem.

Answers

Answer:

For City Bus you will need to ride 10 times for 2 months, and for Campus Transport you need to ride 16 times.

Step-by-step explanation:

$2.50 x 2 = $5.00 so you know that the number of rides needs to even in order to have a whole number. This is because there is no way the City Bus cost will ever have cents.

$2.50 x 16 = $40.00

$15 x 2 = $30

$1 x 10 = $10

$30 + $10 = $40

So (15 x 2) + (10 x 1) = 16 x 2.50
