Find the surface area of the square pyramid shown. Label the net to help you.
I have to show work
Answers
Answer: 40 inches squared
Labels are in the pictures
Step-by-step explanation:
To find the surface area, find the area of each side.
Square (base) : side * side = 4*4 = 16
Triangle (sides) : (base * height)/2
Assuming each side is a isosceles triangle, the base 4/2 = 2
(2*6)/2 = 12/2 = 6
Since there are 4 triangles, we can multiply 6 by 4 to get the combined area. We then add the area of the square to get the final result.
6*4 + 16 = 24+16 = 40

Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.
a. PossibilitiesAs the tree diagram shows, the number of possible meals is ...
(possible meats)×(possible fruits)×(possible desserts)
= 3×2×2 = 12
There are 12 possible lunch options.
b. CookiesHalf the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:
P(no cookie) = 1/2

A swimming pool is 22 feet long and 18 feet wide. How many feet of fencing are needed to enclose the pool
Answers
Answer:
80 feet
Step-by-step explanation:
length of pool = 22 , width of pool = 18
feet required for fencing the pool = 2 (l +b)
= 2 ( 22+18)
=2*40
=80feet
Answer:
Step-by-step explanation:
The pool is a rectangle as length and breadth are different.
Since they are asking about fencing you need to find the perimeter.
Length=22feet
Breadth=18feet
Perimeter of a rectangle = 2(l+b)
= 2 × 22 + 2×18
=44+36
=80 feet

Kieran’s wallet contains 7 bills: three $5 bills, two $10 bills, one $20 bill, and one $100 bill. If Kieran pulls out two bills at random, what is the probability that he selects exactly two $5 bills? Use complete sentences to explain the probability. In your final answer, include all of your calculations.
Answers
Answer:
Exact probability = 1/7
(Approximate probability = 0.142857)
========================================================
Explanation:
There are three 5 dollar bills out of 7 total. The probability of selecting a five dollar bill is 3/7. Let A = 3/7 since we'll use it later.
After the first selection is made, we have 3-1 = 2 five dollar bills left out of 7-1 = 6 bills overall. This is assuming we do not put the first selection back, or replace it with another five dollar bill.
The probability of selecting another five dollar bill is 2/6 = 1/3. Let B = 1/3.
Multiply the values of A and B to get
A*B = (3/7)*(1/3) = (3*1)/(7*3)= 1/7
Note the 3's divide and cancel out.
Using a calculator, 1/7 = 0.142857 approximately
Answer:
1/7
Step-by-step explanation:
$5 = 3, $10= 2, $20= 1, $100= 1- total 7 bills
Probability of getting $5 bill is 3/7Probability of getting second $5 bill is 2/6= 1/3 as one of $5 bill already taken and total number of bills reduced to 6Probability of getting 2 of $5 bills is the product of individual probabilities: 3/7*1/3= 1/7Answer is 1/7

Step-by-step explanation:
You count the units of the length and width of the triangle which is also the same for the rectangle and l*w=the area (length is the longer side).
Halve the area of the rectangle to find the area of the triangle.
The area of this triangle is determined by forming a rectangle is 12.5 square units.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
The area of this triangle is determined by forming a rectangle.
The dimensions of the rectangle are 5 and 2.5.
Area of triangle = Area of rectangle
Area of rectangle = Length × Width
Area of rectangle = 5 × 2.5
Area of rectangle = 12.5
Then the area of the triangle is 12.5 square units.

The graph of y = x2 - 4x is shown on the grid.
By drawing the line y = x -4,
solve the equations:
y = x²- 4x
y=x-4
x=1 y=...
or
x=... y=...
Answers
Answer:
Attached pleased find the screen grab of the graph with the line y = x - 4 included
The solution of the system of equations, y = x² - 4·x and y = x - 4 is directly found from the graph by the points of the intersection of the lines y = x² - 4·x and y = x - 4 which are (4, 0) and (1, -3)
x = 1 y = -3
or
x = 4 y = 0
Step-by-step explanation:
To verify, we have;
Equations y = x² - 4·x and y = x - 4 can be solved where they are equal as follows
Thus equating the value of y in both equations gives;
x² - 4·x = x - 4
x² - 4·x -x - 4 = 0
x² - 5·x + 4 = 0
(x - 4) × (x - 1) = 0
Therefore; x = 4 or 1
When x = 4, y = x - 4 = 1 - 4 = -3.
