Answer:

2.75cm

Step-by-step explanation:

Given data

Area of circle=  23.79cm^2

We know that the formula for the area of a circle is

Area= πr^2

Substitute

23.79=3.142*r^2

23.79/3.142= r^2

7.57=r^2

Square roo both sides

r= √7.57

r= 2.75 cm

Hence the radius is 2.75cm

Answer:

angle 2 = 128 because of a rule that I unfortunately cannot remember the name of....

angle 6 = 180 - 47 = 133

because a straight line = 180 degrees

angle 3 = 180 - 128 = 52

Same reason as angle 6

angle 1 = 52 + 47 = 99

180 - 99 = 81

Sum of the angles in a triangle = 180

All of the underlined numbers are the answers

Answer: 120,000 meters²

Step-by-step explanation:

First find the area of all the land both paved and unpaved:

= Length * Width

= 260 * 500

= 130,000 meters²

The find the area paved:

= 50 * 200

= 10,000 meters²

The area left unpaved:

= Total area - Paved area

= 130,000 - 10,000

= 120,000 meters²

Answer;

The correct answer here is constant multiplier of 1.5

Step-by-step explanation:

To get the constant multiplier, we have to take a look at the y values

subsequent y values were obtained by multiplying the preceding y value with a term

So we have it that;

3.6/2.4 = 5.4/3.6 = 8.1/5.4 = 1.5

The correct answer here is constant multiplier of 1.5

Step-by-step explanation:

Answer:

(a)  s = the original price = $28.38 / 0.67 = $42.36

Step-by-step explanation:

Let s represent the original price of the snowsuit.  

If $28.38 is a discount of 33% from the original price, then (1.00 - 0.33)s = $28.38, or 0.67s = $28.38.

(a)  s = the original price = $28.38 / 0.67 = $42.36

(b) if taxes are 7% then the sale price is (1.07)($42.36) = $45.32.

Of course, if the tax rate is other than 7%, the total sale price will be different.

Answer:

Here we want to complete the blank to make the equality true:

( ) = (2 - 6)*(-4)

The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:

x = (2 - 6)*(-4)

We just need to find the value of x.

Then let's solve the right side:

x = (2 - 6)*(-4) = (-4)*(-4)

Remember the rule of signs:

(-)*(-) = (+)

x = (-4)*(-4) = 4*4 = 16

Then we need to complete the blank with the number 16

(16) = (2 - 6)*(-4)

Answer:

k = 3.9

Step-by-step explanation:

Since the three possible outcomes are given. Therefore, the sum of all the probabilities of the three possible outcomes will be equal to one:

[tex]\frac{7}{13} +\frac{1}{k}+ \frac{1}{2k} = 1 \\\\\frac{1}{k} \frac{1}{2k} =1-\frac{7}{13}\\\\\frac{3}{2k} \frac{5}{13}\\\\2k = \frac{(13)(3)}{5}\\\\k = \frac{39}{(5)(2)}\\[/tex]

k = 3.9

Step-by-step explanation:

The probability that a randomly selected senior voted for an eagle mascot is 11/68.

Given that, the Central High School students voted to select a school mascot. The results of the vote are recorded in the table.

We need to find what is the probability that a randomly selected senior voted for an eagle mascot.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favourable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Now, probability = 55/340 =11/68

Therefore, the probability that a randomly selected senior voted for an eagle mascot is 11/68.

Answer:

Yes it will fit

Step-by-step explanation:

The area of the bedroom, since it's a square, would be 12ft * 12ft = 144ft²

The area of the circular rug would be πr² = π(40.82/2π)² = 132.6ft²

Since 144ft²>132.59ft², this means that the 132.6ft² circular rug would be able to fit into the 144ft² bedroom.
