Find the area of the regular polygon. Round to the nearest tenth.

Answer:

One rose bush costs $6

One pot of ivy costs $5

Step-by-step explanation:

Set up an equation:

Variable x = cost of rose bushes

Variable y = cost of pots of ivy

3x + 3y = 33

12x + 4y = 92

I will use substitution to first solve for x:

3y = 33 - 3x

Divide both sides by 3

y = 11 - x

Substitute y value for 11 - x:

12x + 4(11 - x) = 92

Use distributive property

12x + 44 - 4x = 92

Combine like terms

8x + 44 = 92

8x = 48

Divide both sides by 8

x = 6

Solve for y by plugging in 6 for the x value:

3(6) + 3y = 33

18 + 3y = 33

3y = 15

Divide both sides by 3

y = 5

Check work:

3(6) + 3(5) = 33

18 + 15 = 33

33 = 33

Correct

Answer:

V = 260.2 m^3

Step-by-step explanation:

The area of the circular base is (pi)(r)^2, where r is the radius and half the diameter.

In this case the volume of the cone is V = (1/3)(pi)(5 m)^2*(10 m) = 260.2 m^3

The larger number is 67 while the smaller number will be 19 for the given condition.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given,

Suppose the larger number is x while the smaller number is y.

Sum will be as x + y = 86

The larger number is nine less than four times the smaller number.

x = 4y - 9

By substitution,

4y - 9 + y = 86

5y = 95

y = 19

x = 86 - 19 = 67

Hence "For the specified condition, the greater number is 67 and the smaller number is 19".

Answer:

84

Step-by-step explanation:

First you need to find the area of the square. You have to multiply 4x10 which is 40. So now you have to find the area of the triangle. To do that you have to use this equation base x Height/2. Basically 6 times 3.5 is 21/2 so its 10.5. Since you have 2 triangles you can just multiply by 2 which is 42 so 42 + 42 is 84

Step-by-step explanation:

Answer: 18

Explanation: 18 times 2.5 is 45. 45 +18=63

Answer:

the answer would be 25 because to get the answer you would take 63 and divide it by 2.5 and you will get 25.2 then rounding it to the nearest 10th would be 25

then after you get 25 you would put it into the equation 2.5(x) = 63 which would be 2.5(25)=63. that it y 25 would be the correct answer.

C) P (X2 ≤ 8.2) = 0.96

Step-by-step explanation:

P value for the test is the probability of obtaining results that have been observed in the null hypothesis statement. A very small value of p indicates that there is unlikely chance of null hypothesis being true which means that we cannot accept null hypothesis based on the small p value.

Answer:

P(χ2≥8.2)=0.04

Answer:

The degrees of freedom is 6 for the chi square independence test.

Step-by-step explanation:

This is test hypothesis of independence. The test statistic under H0 is

χ²= ∑ (O - E)²/ E

where O is the observed and E is the expected frequency

which  has an approximate chi square distribution with ( r-1) (c-1) degrees of freedom, where r= rows and c= columns.

Here there are 4 rows and 3 columns

Hence the degrees of freedom will be

( 4-1) ( 3-1)= 3*2= 6

Answer:

previous monthly salary is R 308,550 and increment is R 21,450

Step-by-step explanation:

Let the previous monthly salary be x

Current salary = R 330,000

Percent increase = 6,5%

Increase = 6.5% * 330,000

Increase = 0.065 * 330,000

Increase = Rs21,450

Previous salary = 330,000 - 21,450

Previous salary = 308,550

Hence previous monthly salary is R 308,550 and increment is R 21,450
