Answer:
9c^2 - 30cd + 25d^2
Step-by-step explanation:
(3c - 5d)^2
= (3c - 5d) (3c - 5d)
= [3c * 3c] + [3c * -5d] + [-5d * 3c] + [-5d * -5d]
= 9c^2 - 30cd + 25d^2
Use the proportion to solve for the unknown base measure of the enlarged trapezoid. 1.Set up the proportion: StartFraction 2 over 3.25 EndFraction = StartFraction x over 6.5 EndFraction 2.Use cross products: 2(6.5) = 3.25(x) 3.Simplify: 13 = 3.25x 4.Divide both sides by 3.25: The missing base measure of the enlarged trapezoid is cm.
Answer:
The missing base measure of the enlarged trapezoid is 4cm.
Step-by-step explanation:
Step 1:
2 / 3.25 = x / 6.5
Step 2:
Cross product
2 * 6.5 = 3.25 * x
Step 3:
Simplify
13 = 3.25x
Step 4:
Divide both sides by 3.25
13 / 3.25 = 3.25x / 3.25
4 = x
x = 4
The missing base measure of the enlarged trapezoid is 4cm.
Answer:

Jaime ran the first 3 1/3 miles of a 5-mile race in 1/3 hour. What was her average rate, in miles per hour, for this first part of the race? Explain how you solved the problem.
9514 1404 393
Answer:
10 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours:
(3 1/3 mi)/(1/3 h) = (10/3)/(1/3) mi/h = 10 mi/h
Jaime's average rate was 10 miles per hour.

==================================================
Explanation:
Add up everyone in the "has a pet" column to get 22+78 = 100. So we have 100 people who have a pet.
Add up every value in the "male" row to get 22+66 = 88. So there are 88 males
It's tempting to say that 100+88 = 188 people either have a pet or are male, but we're double counting the 22 males who have a pet (top left corner). So we must subtract that value off to get 188-22 = 166
Another way you could look at it is to add up every value that is either in the "has pet" column or is in the "male" row, giving us: 22+78+66 = 166
So there are 166 people who either have a pet, are male, or both.
This is out of 22+66+78+34 = 200 people total
Divide the two values to get 166/200 = 0.83 = 83%

Shelly's square garden has an area of 81ft (squaredi do not know how to do the symbol lol) what is the side of each length please help
[tex]\textit{area of a square}\\\\ A=s^2~~ \begin{cases} s=\stackrel{side's}{length}\\[-0.5em] \hrulefill\\ A=\stackrel{ft^2}{81} \end{cases}\implies 81=s^2\implies \sqrt{81}=s\implies 9=s[/tex]
Answer:
9 ft
Step-by-step explanation:
area of a square = side length × side length = (side length)²
Given:
area of square = 81 ft²side length = x⇒ 81 = x²
⇒ x = √81
⇒ x = 9 ft
A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested. consider the following events: a. the burrito is a chicken burrito. b. the burrito is a carne asada burrito. c. the customer requested black beans. d. the customer requested pinto beans. a 6-column table has 4 rows. the first column has entries black beans, pinto beans, no beans, total. the second column is labeled fish with entries 2, 10, 36, 48. the third column is labeled carne asada with entries 5, 24, 51, 80. the fourth column is labeled vegetarian with entries 1, 8, 20, 29. the fifth column is labeled total with entries 45, 72, 123, 240. which two events are independent? a and c a and d b and c b and d
The two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).
What is the independent events?Independent events are those events whose occurrences do not depend on the other events.
A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested.
Consider the following events:
A. The burrito is a chicken burrito.B. The burrito is a carne asada burrito. C. The customer requested black beans. D. The customer requested pinto beans.The probability of event A is,
[tex]P(A)=\dfrac{83}{240}[/tex]
The probability of event B is,
[tex]P(B)=\dfrac{80}{240}=\dfrac{1}{3}[/tex]
The probability of event C is,
[tex]P(C)=\dfrac{45}{240}=\dfrac{3}{16}[/tex]
The probability of event D is,
[tex]P(A)=\dfrac{72}{240}=\dfrac{3}{10}[/tex]
If the probability of an event is calculated given that the other is happened, only the probability of event B and D we get such that,
[tex]P(B\cap D)=P(B).P(D)\\\dfrac{24}{240}=\dfrac{1}{3}\times \dfrac{3}{10}\\\dfrac{1}{10}=\dfrac{1}{10}[/tex]
Thus, the two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).

Mark McGuire hit 70 home runs in the 1998 season. Given that there are 4 bases & 90 feet between each base, how many miles did he run that season just from home runs?
Answer:
4.8 or about 5 miles
Step-by-step explanation:
In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in one mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

About how many people live in all three countries altogether?
Answer:
About 4.69 x 10^8 people live in all three countries altogether
Step-by-step explanation:
3.9 x 10^7 is .39 x 10^8
now you can make x 10^8 into y

Circle A has a circumference of 25 centimeters. Circle B's diameter is 3 times as long as circle A’s diameter. What is the circumference of circle B?
- And don’t say 10 because it’s wrong
Answer: 74.98cm
Step-by-step explanation:
Step 1: Find out radius of Circle A. [We use circumference of circle A to find its radius].
Circumference of circle A = 2πr; where r is radius.
To better viewing we change sides, we get:
2πr = Circumference of circle A
2πr = 25
r = [tex]\frac{25}{2\pi }[/tex]
r = [tex]\frac{25}{3.14}[/tex]
r ≈ 3.98
Step 2: Calculate the diameter of circle A.
diameter of circle A = 2r = 2(3.98) = 7.96
Step 3: Finding diameter of circle B.
diameter of circle B = 3(diameter of circle A) = 3(7.96) = 23.88
Step 4: Converted diameter of circle B to r.
diameter of circle B = 2r
23.88 = 2r
divided 2 from both sides, we get:
11.94 = r
Step 5: Substitute radius of circle B into the circumference formula, where C = 2πr.
C = 2πr
C = 2(3.14)(11.94)
C ≈ 74.98

What is the slope of the line that passes through the points (2, 9)(2,9) and (18, -3)(18,−3)? Write your answer in simplest form.
(2 ; 9) and (18 ; - 3)
slope = (-3 - 9) / (18 - 2) = -12/16 = -3/4 or - 0,75
Slope of the line that passes through the points (2, 9) and (18, -3) is -2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b
where m is the slope and b is y intercept.
The formula to calculate slope passing through two points (x1, y1) and (x2, y2) is
m= (y₂- y₁)/(x₂-x₁)
The given two points are (2, 9) and (8, -3)
Here x₁=2, y₁=9, x₂=8, and y₂=-3
Substitute the values in formula of slope.
m=-3-9/8-2
m=-12/6
m=-2
Hence slope of the line that passes through the points (2, 9) and (18, -3) is -2.
