The circle above has a radius of 9 cm. What is the area of the circle?
(Use PI = 3.14)
Answers
answer: 254.469
On this exercise is given that the radius of the circle is 9 cm and it is asked to find its area and use 3.14 as the value of π. Therefore, to find the area of the circle you should substitute the value of the radius and the value of pi into the formula A=πr^2.
A=πr^2
A=(3.14)(9)^2
A=(3.14)(81)
A=254.34

The result of rounding the whole number 53,679,012 to the nearest millions place is: 53,000,000. 50,000,000. 53,600,000. 54,000,000.
Answers
Final answer:
The number 53,679,012 rounded to the nearest million is 54,000,000. The digit in the hundred thousands place determines whether to round up or down. In this case, since it's a 6 (which is >= 5), we round up.
Explanation:
Rounding Whole Numbers to the Nearest Million
To round the whole number 53,679,012 to the nearest million, we need to look at the digit in the hundred thousands place, which is 6. Since this digit is 5 or greater, we round up. Therefore, we increase the digit in the millions place by one, giving us 54,000,000 as the rounded number to the nearest million.
For example, consider another number like 52,700,000. Using the same rounding principle, since the digit in the hundred thousands place is 7, which is greater than 5, we would round up to 53,000,000.
When rounding large numbers, the key is to look at the digit immediately to the right of the place value you are rounding to. If this digit is 5 or higher, you round up, and if it is 4 or lower, you round down.
What is 60% of 60? need help with this one can some one show me how to do it?
Answers
60 x 0.6 = 36
If we wanted to do it another way, we could multiply 60 by 0.5 and 0.1 seperately and add those numbers up.
[tex]\dfrac x{60}=\dfrac{60}{100}=60\%[/tex]
Multiply both sides by 60, so that
[tex]\dfrac{60x}{60}=\dfrac{60^2}{100}\implies x=\dfrac{3600}{100}=36[/tex]
Another way of doing it: you can easily find that 10% of 60 is 6. Then 60% would be 6 times 10%, and 6 times 6 is 36.

Drake wants to save $750 so that he can take a class on computer analysis for cars. The class is being held on various dates over the next several months. Drake is planning to take the class 6 weeks from now, so he plans to save $125 each week. Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470. He knows that he must adjust his plan in order to meet his goal. Drake came up with the following options: Option A: Stay with saving the original amount each week but take the class a week later than originally planned. Option B: Increase the amount of money he saves each week by $15 from his original plan. Which of the following is a true statement? a. Only option A will allow him to meet his goal. b. Only option B will allow him to meet his goal. c. Both options A and B will allow him to meet his goal. d. Neither option A nor option B will allow him to meet his goal.
Answers
answer- C
total money required = 750
total money saved = 470
weeks left = 2
money earned in each week = 125
money earned in 2 weeks = 250
470 + 250 = 720( so, drake is short of 30 )
option A- by postponing the classes for 1 week, he will earn 125 more, so it is an option to meet his goal as 125>30
option B- by increasing the savings by 15 for two weeks, he will save 30 more which is the amount drake needs. so , it is also a good option

A kite has a height of 36 inches and a width of 30 inches. Explain how to use the area formula for a triangle to find the area of the kite.
Answers
Height of the kite is = 36 inches.
Width of the kite is = 30 inches
One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .
Now we will use the formula [tex]area=\frac{1}{2}*base*height[/tex] to find the area of each triangle. Then we will add both the areas to find the area of the kite.
Area of 1 triangle = [tex]\frac{1}{2}*36*15[/tex] = 270 square inches
Area of the 2nd triangle is also = 270 square inches
Hence, area of the kite = 270+270 = 540 square inches
The area of the kite is 540 square inches
The dimension of the rectangle is given as:
Height = 36 inches. Width = 30 inches
The area of the kite is then calculated using:
[tex]Area = \frac 12 \times (Height \times Width)[/tex]
Substitute values for Height and Width
[tex]Area = \frac 12 \times (36 \times 30)[/tex]
Evaluate the expression in bracket
[tex]Area = \frac 12 \times 1080[/tex]
Evaluate the product
[tex]Area = 540[/tex]
Hence, the area of the kite is 540 square inches

Answers
Answer:

Step-by-step explanation:
The general equation of a line in the xy plane is as follows:
[tex]y = mx + b[/tex]
where [tex]m[/tex] is the slope of the line, and [tex]b[/tex] is the intercept with the y axis.
In this case we want a line with a slope of -4, therefore:

and we also want a y-intercept of -2, so:
[tex]b = -2[/tex]

A single die is rolled twice. find the probability of rolling an odd number and a number greater than 4 in either order.
Answers
The probability of rolling an odd number and a number greater than 4 in either order is 1/6.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, a single die is rolled twice,
∴ The 36 outcomes are
(1,1),(1,2)...(1,6),(2,1)...(2,6),(3,1)...(3,6),(4,1)...(4,6)...(5,1)...(5,6)...(6,1)...(6,6).
So, N(S) = 36.
The no of favorable outcomes N(F) an odd number and a number greater than 4 in either order are [{(1,5),(1,6),(3,5)(3,6),(5,5),(5,6)} as given they can occur in either order so (1,5) and (5,1) are one combined.
∴ N(F) = 6.
So, The probability P(F) of rolling an odd number and a number greater than 4 in either order is,
P(F) = N(F)/N(S).
P(F) = 6/36.
P(F) = 1/6.

The probability of rolling an odd number and a number greater than 4 in either order when a single die is rolled twice is 1/18.
To find the probability of rolling an odd number and a number greater than 4 in either order when a single die is rolled twice, we need to first identify the possible outcomes. The odd numbers on a die are 1, 3, and 5. Since we are also looking for a number greater than 4, the only possible outcomes that meet both conditions are 5 and 6.
When the die is rolled twice, there are 6 x 6 = 36 possible outcomes. There are two favorable ways to achieve the goal: Roll a 5 (odd) first and then a 6 (greater than 4), or roll a 6 first and then a 5. Thus, there are two successful outcomes: (5, 6) and (6, 5). The probability of each individual outcome is 1/36, so the combined probability is 2/36, which simplifies to 1/18.
Therefore, the probability of rolling an odd number and a number greater than 4 in either order with a single die rolled twice is 1/18.

Answers
Answer:
Mica should have added 2 to 3 instead of 1.
Step-by-step explanation:
f(x) = 2x^2 – 4x – 3
0 = 2x^2 – 4x – 3
Mica added 3 on boths sides and factored out 2
3 = 2(x^2 – 2x)
We have 2 outside the parenthesis , so we multiply 1 with 2 and add it one left side
3 + 1 = 2(x^2 – 2x + 1) Error in this step
The above step becomes 3 + 2 = 2(x^2 – 2x + 1)
Mica should have added 2 to 3 instead of 1.
