Answers

Answer 1

9514 1404 393

Answer:

  36°

Step-by-step explanation:

Each exterior angle is 360°/5 = 72°. This is the base angle of the isosceles triangle formed by drawing a line opposite angle y at the corners of the pentagons.

The angle y is ...

  y = 180° -2(72°)

  y = 36°

Answer:

x = 65

Step-by-step explanation:

straight line = 180 degrees

so

180 - 165 = 25

90 + 25 = 115 degrees

180 - 115 = 65 degrees

so

x = 65

The volume of a cone, V , varies jointly with its height, h , and the square of its
radius, r . If k is the constant of proportionality, which of the following equations
represents the correct relationship between volume, radius, and height?

Answers

An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,

V ∝ h(r²)

Also, k is the constant of proportionality, therefore, the equation now can be written as,

V = k×h×r²

Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

the last one

Step-by-step explanation:

32+26=58

32-26=6

Answer:

The first number is 32 and the second is 26

Step-by-step explanation:

Let the two numbers be represented by x and y

1) x + y = 58

2) x - y = 6

x = 6 + y, we'll use put this in the first equation.

x + y = 58

6 + y + y = 58

6 + 2y = 58

2y = 58 - 6

2y = 52

2. 2

y=26, now let's find x, again use the first equation

x + y = 58

x + 26 = 58

x = 58 - 26

x = 32

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, there are 20 students in a drama club,

5 of them will leave in next year, and d students will join,

We are asked to construct an expression to represent the total number of students in the drama club next year.

So, the present number of students in the club = 20

After next year = 20-5 = 15

After the joining = 15+d

Hence the expression showing the number of students in the drama club the next year is 15+d.

3. Find any three rational numbers between 1/2 and 3/2​

Answers

Answer:

[tex] \frac{2}{3} \\ \\ \frac{2}{2} \\ \\ \frac{4}{3} [/tex]

Step-by-step explanation:

I hope that is useful for you :)

Answer:

For example 1/1, 2/3 and 4/3

Step-by-step explanation:

There is a great way to generate rational numbers between other rational numbers using:

[tex]\textrm{If:~~~~~~} \frac{a}{b} < \frac{c}{d}\vspace{7pt}\\\textrm{Then:~} \frac{a}{b} < \frac{a+c}{b+d} < \frac{c}{d}[/tex]

So we know that (1+3)/(2+2) is between 1/2 and 3/2 without checking.

(1+3)/(2+2) = 1/1, so we got our first rational number.

Lets continue by finding numbers between 1/2 and 1/1; and 1/1 and 3/2

(1+1)/(2+1) = 2/3

(1+3)/(1+2) = 4/3

We could also look for a number between 1/2 and 2/3 and find

(1+2)/(2+3) = 3/5

And so on, so forth :)

Stefan sells Jin a bicycle for ​$125 and a helmet for ​$18. The total cost for Jin is ​130% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend​ originally? How much money did he make by selling the bicycle and helmet to​ Jin?

PLEASE TELL ME AN ANSWER, THIS TEST IS DUE IN 5 MINUTES.

Answers

Answer: The selling cost for Stefan bicycle = $114 and

the selling cost of a helmet = $18.

The total cost for Jin is 120% of the money spent.

Let us assume purchasing cost of a bicycle = $x.

Purchasing cost of a halmet = $y.

For bicycle

120% of x is $114  

=>  1.20 × x = 114

Dividing both sides by 1.20, we get

x=$95.

For helmet.

120% of y is $18.

=> 1.20 × y = 18.

Dividing both sides by 1.20, we get

y = $15.

Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.

$114 - 95 = $19

$18 - 15 = $3.

Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.
