Answer:

k= -7

Step-by-step explanation:

multiple both sides of the equation by 56.

16k - 21 = -133

move the constant to the right hand side and change its sign.

16k = -133 + 21

Calculate the sum.

16k= -112

Divide both sides by 16.

k = -7

Solution is K = -7

Part two.

Take away 19.5 from 40 to get your answer.

your answer is then less than forty so it's the symbol <.

I am not entirely sure on this second part I would get someone to double check it as I'm not the best at inequalities and such. If any help is needed with what I done just ask.

PTG has side lengths of 18 cm, 27 cm, and 13 cm. which type of triangle is PTG? The answer is obtuse.

Verizon [17]

To know what kind of triangle is it. use the pythagorean theorem:
A^2 + B^2 = C^2,
where C is the longest side of the triangle
if it satisfies the equation then it is a right triangle
if it does not then A^2 + B^2 > C^2 so it is acute triangle
if A^2 + B^2 < C^2 it is obtuse triangle

18^2 + 13^2 ? 27^2
324 + 169 ? 729
493 < 729 so it is obtuse triangle

Suppose that the probability that your mail is delivered before 2 pm is .90. What is the probability that your mail will be deli

iren2701 [21]

Given that the probability of mail being delivered is 0.90, to evaluate the probability that the mail will be delivered before 2 p.m for 2 consecutive days will be evaluated as follows:
Let the probability that the milk will be delivered before 2 p.m be P(x). Since the two days are independent events, the probability of the mail being delivered before 2 p.m in 2 consecutive days will be:
P(x)×P(x)
=0.9×0.9
=0.81

Which of the following gives all of the sets that contain -1/2?

fiasKO [112]

ANSWER

The set of all rational numbers and the set of all real numbers.

EXPLANATION

The set of rational numbers contains all numbers that can be written in the form,

$\frac{a}{b}$

where a and b are integers and b≠0.

The given number is

$- \frac{1}{2}$

It belongs to the set of rational numbers.

The set of rational numbers is a subset of the set of real numbers.

Hence

$- \frac{1}{2}$
also belongs to the set of real numbers.

The correct answer is A.

Problem 2 Find all the divisors of the number 2,310. How do you know that you found them all?

elena-s [515]

9514 1404 393

Answer:

1, 2, 3, 5, 6, 7, 10, 11, 14, 15, 21, 22, 30, 33, 35, 42,

55, 66, 70, 77, 105, 110, 154, 165, 210, 231, 330, 385, 462, 770, 1155, 2310

Step-by-step explanation:

The trailing digit is 0, and the sum of digits is 6, so we know the number is divisible by 2, 3, 5. Dividing out those factors, we get a quotient of 77, which is 7×11. This means the prime factorization is ...

2×3×5×7×11 = 2310

There are 5 prime factors, each with an exponent of 1, so the total number of divisors is 2^5 = 32. We will have found them all when all 32 are listed.

1, 2, 3, 5, 6, 7, 10, 11, 14, 15, 21, 22, 30, 33, 35, 42,

55, 66, 70, 77, 105, 110, 154, 165, 210, 231, 330, 385, 462, 770, 1155, 2310

Of course, the pairwise products working toward the center from the ends of the list are all 2310.

Marty has saved $72. He spent $8 on a video rental. Write a ratio as a fraction in simplest form to represent what portion of hi

Natalka [10]

The solution to the problem is as follows:

The savings left is just $72 - $8 = $64.
Therefore, the ratio is $64 : $72 = 8 : 9.
