Answers

Answer:

the answer is 13 .

Step-by-step explanation:

it is a right angle which is 90 degrees, they already gave you 53 and 24 so you add those and get 77. then you subtract 77 from 90. that gives you 13!

Answer:

Start with: sin 53° = 24/w

Multiply both sides by w: w × (sin 53°) = 24

Divide both sides by "sin 53°": w = 24 / (sin 53°)

Calculate: w = 24 / 0.79863551

 w = 30.1

Write the fraction 9/54 in simplest form.​

Answers

Answer: 1/6

9 goes into 9 once

9 goes into 54 six times

The simplified form of the given fraction 9/54 is 1/6.

To simplify the fraction 9/54, we can find the greatest common divisor (GCD) of the numerator and the denominator, and then divide both the numerator and the denominator by the GCD.

The factors of 9 are 1, 3, and 9, while the factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.

The highest common factor of 9 and 54 is 9.

Dividing both the numerator and the denominator by 9, we get:

9 ÷ 9 = 1

54 ÷ 9 = 6

Therefore, the simplified form of the given fraction 9/54 is 1/6.

1 meter of ribbon costs $3
how much do you pay for 2 3/4
If correct I will brainest u

Answers

Answer:

You pay $8 [tex]\frac{1}{4}[/tex] for 2 [tex]\frac{3}{4}[/tex] meters of ribbon

Step-by-step explanation:

Let us solve the question

∵ 1 meter of ribbon costs $3

∵ We need to find the cost of 2 [tex]\frac{3}{4}[/tex] meters

→ Separate the length of the ribbon to a whole number and a fraction

∵ The length of the ribbon = 2 m + [tex]\frac{3}{4}[/tex] m

→ Multiply each part by the cost of 1 meter

∵ The cost of 1 meter = 3 dollars

∴ The cost of the ribbon = 3 × 2 + 3 × [tex]\frac{3}{4}[/tex]

∴ The cost of the ribbon = 6 + [tex]\frac{9}{4}[/tex] dollars

→ Change the improper fraction [tex]\frac{9}{4}[/tex] to a mixed number

∵ 9 ÷ 4 = 2 [tex]\frac{1}{4}[/tex]

∴ The cost of the ribbon = 6 + 2 + [tex]\frac{1}{4}[/tex]

∴ The cost of the ribbon = 8 + [tex]\frac{1}{4}[/tex]

∴ The cost of the ribbon = 8 [tex]\frac{1}{4}[/tex] dollars

∴ You pay $8 [tex]\frac{1}{4}[/tex] for 2 [tex]\frac{3}{4}[/tex] meters of ribbon

what is the Riemann hypothesis

Answers

in mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part
1
/
2
. Many consider it to be the most important unsolved problem in pure mathematics (Bombieri 2000). It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.

Answer:

What is the Riemann hypothesis simply explained?

The Riemann hypothesis asks if every non-trivial root (white dot) would be on the line down the middle. If the answer is no, we say the "hypothesis is false". This would mean that there are white dots which are not on the line given.

A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-
values?
o As the x-values increase, the y-values tend to increase.
As the x-values increase, the y-values tend to decrease.
As the x-values decrease, the y-values tend to increase.
O As the x-values decrease, the y-values tend to vary randomly.

Answers

Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

Answer:

a: As the x-values increase, the y-values tend to increase.
