Answer 1

Answer: m(<BAC) = 180 - 70 - 65 = 45 degrees;
but, m(<A) < m(<B) < m(<C) => BC < AC < AB (3);

Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.

$\text{ tangent}^2=\text{whole secant}\cdot \text{exterior secant}$ .

The whole secant with exterior secant 5 in is 5+y in. Using this theorem you can state that

$9^2=(5+y)\cdot 5$ .

Solve this equation:

$81=25+5y,\n 5y=81-25,\n 5y=56,\n y=11.2$ in.

Answer: y=11.2 in.

Anna invests $875 into an account and receives 4% simple interest for 24 months. How much simple interest will she earn??

Answers

Answer:

$70

Step-by-step explanation:

1. I = PRT

2. Sub in what you know into the equation:

I = $875 (principal amount) x 0.04 (4%) x 2 (24 months = 2 years)

3. 875 x 0.04 x 2 = 70

4. Anna will receive $70 in simple interest

Answer:

£70

Step-by-step explanation:

simple interest (I) is calculated as

I = $(PRT)/(100)$

where P is principal, R is rate of interest and T is time in years.

Note that 24 months = 2 years, thus

I = $(875(4)(2))/(100)$ = $(7000)/(100)$ = £70

What is the perimeter of abc with vertices A(-2,9) B(7,-3) and C(-2,-3) in coordinate plane

Answers

For the answer to the question above,
A - C = ( -2, 9) - (- 2 -3)

= ( 0, 12)

AC = 12

B - C = (7 - 3) - ( - 2 -3)

= (9, 0)

BC = 9

ABC is a right -angled triangle with AC as the hypotenuse

AC = sqrt( 9^2 + 12^2)

= sqrt(81 + 144)

= srqt(225)

= 15

Perimeter = 12 + 9 + 15

= 36 units

So the answer is 36 units

In Jonah’s restaurant, each table seats 4 people. Jonah has 78 napkins to place at the tables. How many napkins will jonah need to complete one more table?

Answers

Answer:

Jonah needs 2 more napkins to complete one more table.

Step-by-step explanation:

In Jonah’s restaurant, each table seats 4 people.

In total Jonah has 78 napkins to place at the tables.

So the total number of napkins must be a multiple of 4.

But unfortunately 78 is not a multiple of 4. It leaves a remainder of 2 while divided by 4.

So, the number which is 2 more than 78 will be a multiple of 4 and will complete the set of tables i.e 80

Therefore, Jonah needs 2 more napkins to complete one more table.

78 napkins ÷ 4 people per table = 19 tables remainder 2 napkins.
A table needs 4 napkins and we only have 2. This means that we will need 2 more napkins in order to complete one more table.
