what is the approximate circumference of the circle shown below?​

Answer:

Les deux nombres doivent avoir une différence de 3. Algébriquement, ce serait x + (x + 3) = 129. 2x est alors égal à 126. X est égal à 63 et x + 3 est à 66. Ces nombres sont des multiples consécutifs de 3 dont la somme est de 129.

Step-by-step explanation:

The two numbers must have a difference of 3. Algebraically, it would be x + (x + 3) = 129. 2x then is equal to 126. X equals 63 and x + 3 is 66. These numbers are consecutive multiples of 3 whose sum is 129.

Answer:

-67/540

Step-by-step explanation:

I just converted - 80% to a decimal which is - 0.8 and then used a calculator for the rest.

The percentage of failed students is 12%

We have,

Total number of students = 175

Number of students passed = 154

We need to calculate the percentage of the number of failed students.

The formula used to calculate the percentage is:

     [tex]\frac{ required~value}{total~value} \times 100[/tex]

Here,

Total value:

= Total number of students

= 175

Required value:

= Number of students failed

= Total number of students - Number of students passed

= 175 - 154

= 21

Percentage of failed students:

=  [tex]\frac{21}{175} \times 100\\[/tex]

= ( 21 x 100 ) / 175

= 2100 / 175

= 12 %

The percentage of failed students is 12%.

Answer:

it's D

Step-by-step explanation:

The inequality that represents Dan's purchase is 0.85x + 1.29y < 5.

The correct option is D.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

The cost of x pounds of potatoes at $0.85 per pound is 0.85x dollars.

The cost of y pounds of grapes at $1.29 per pound is 1.29y dollars.

The total cost of the purchase is the sum of these costs, which is:

0.85x + 1.29y

The inequality that represents the total cost being less than $5 is:

0.85x + 1.29y < 5

So, the correct answer is 0.85x + 1.29y < 5.

Answer:

first we need to find the LCM of the given numbers i.e. 8, 12, 15 and 20

2*2*2*5*3=120

Then

as 2, 3, 5 are not in pairs, we need to multiply the LCM with 2*5*3=30

so,

least perfect square number which is divisible by each of numbers 8 12 15 and 20

Hello can we be friends.....

Answer:

L1 = 18 cm

W1 = 14 cm

A1 = 252 cm²

Step-by-step explanation:

Since the small rectangle is ½ the scale drawing of the original figure, therefore the dimensions of the smaller rectangle would be half of that of the original.

Thus:

Length (L) of the original = 36 cm

Length (L1) of the smaller rectangle = ½(36) = 18 cm

Width (W) of the original = 28 cm

Length (W1) of the smaller rectangle = ½(28) = 14 cm

Area (A1) of the smaller rectangle = L1 × W1 = 18 × 14 = 252 cm²

Answer:

Step-by-step explanation:

very easy.

this simply means what is the value of x, so that the result of the function is 7.

remember, the domain is the interval of valid values for x.

and the range is the interval of valid values of y (or functional results).

so,

7 = (3x - 4)/2

14 = 3x - 4

18 = 3x

x = 6

so, for x = 6 the function delivers 7 as result.

Answer:

x = 17.1

Answer:

D

Step-by-step explanation:

Since ∠ RPQ = ∠ SPQ = 60° , then

PQ bisects ∠ RPS and is an angle bisector

PQ exists the angle bisector of angle RPS. It means PQ divides the angle RPS in two equivalent parts.

Angle bisector in geometry directs to a line that divides an angle into two equivalent angles. A bisector represents the thing that bisects a shape or an object into two equivalent regions. If we draw a ray that bisects an angle into two equivalent parts of the exact measurement, then it exists named an angle bisector.

It is given that ray PQ is the angle bisector of angle RPS. It means PQ divides the angle RPS in two equivalent parts.

[tex]$m \angle R P Q=m \angle QP S=60^{\circ}$[/tex]

Now, [tex]&m \angle R P S=m \angle R P Q+m \angle Q P S \\[/tex]

[tex]&m \angle R P S=60^{\circ}+60^{\circ} \\[/tex]

[tex]&m \angle R P S=120^{\circ}[/tex]

Therefore, the measure of angle RPS is [tex]$60^{\circ}$[/tex].

Therefore, the correct answer is option D. angle bisector.

Step-by-step explanation:

Step 1:  Check to see if Connor is right

25 divided by the difference of 12 and seven

25 / (12 - 7)

Since we have a 12 and seven, that means that we have them together.  However, how Connor is presenting it, it would be 25 divided by 12 subtracted 7.  Therefore, Connor is incorrect.

Answer:

No he's not correct.

Step-by-step explanation: Let's take a step back and look at the question, he wants to represent the difference of 12 and 7 ÷ by 25. Therefore in order to do that we need to figure out the difference 12 and 7 so the equation would look like this 12-7=5  after doing that we divide 5 by 25 so it would look like this 25÷5=5.

So the correct equation is (12-5) ÷25

Answer:

I think 5q+3(8-q) =36 is the answer for this question

Based on the amount the restaurant manager spends on the juice mixture, the amount of cherry juice can be found as 5q + 3(8 – q) = 8.

Assuming the cherry juice is q and the lime juice is r, the following formulas would be true:

q + r = 8

5q + 3r = 36

The first equation can be rewritten as:

q + r = 8

r = 8 - q

Using substitution into the second formula we get:

5q + 3r = 36

5q + 3(8 - q) = 36
