A square pyramid has a base edge of 1 meter. The height of each triangular face is 1 meter. What is the pyramid's surface area?
Answers
Answer:
A square pyramid has 5 faces: 1 square base and 4 triangular faces.
The area of the base is:
A = s^2
where s is the length of the base edge.
In this case, s = 1 m, so:
A = 1^2 = 1 m^2
The area of each triangular face is:
A = 1/2 * b * h
where b is the base of the triangle (which is equal to the length of one side of the square base) and h is the height of the triangle (which is given as 1 m).
In this case, b = 1 m and h = 1 m, so:
A = 1/2 * 1 * 1 = 0.5 m^2
The total surface area of the pyramid is the sum of the area of the base and the area of the four triangular faces:
SA = A_base + 4 * A_triangles
SA = 1 + 4(0.5)
SA = 1 + 2
SA = 3 m^2
Therefore, the surface area of the pyramid is 3 square meters.

6. Which destination is more popular, the skating rink or the water park? (2 points)
Answers
Here is the completed table:
Water park Skating Total
Boys 60 55 115
Girls 50 45 95
Total 110 100 210
The boys that went skating is 55.
The relative frequency of boys who want to go to the water park is 0.52.
The probability that a randomly selected student is a girl who wants to go skating is 0.21.
There are more boys than girls.
What is the two way frequency table?
Total number of girls = 50 + 45 = 95
Total number of boys = 210 - 95 = 115
Total number of boys that want to skating = 115 - 60 = 55
Total number of students that go to the water park = 60 + 50 = 110
Total number of students that want to go skating = 45 + 55 = 100
The relative frequency of boys who want to go to the water park = number of boys who want to go to the water park / total number of students
110 / 210 = 0.52
The probability that a randomly selected student is a girl who wants to go skating = number of girls that want to go skating / total number of students
45 / 210 = 0.21

13 A young girl standing on a cliff is throwing stones up into the air so that they land in the ocean below. The height h, in meters, of each stone above the ocean is related to the
time 1, in seconds, after it has been thrown by the function
h = -21? + 21 + 40. What is the maximum height reached by
each stone?
Answers
The maximum height reached by each stone is 40.5 meters.
The height of each stone above the ocean is given by the function:
h = -2t² + 2t + 40
This is a quadratic function in standard form, with a = -2, b = 2, and c = 40.
The maximum height reached by the stone occurs at the vertex of the parabolic curve described by this function.
The t-coordinate of the vertex is given as:
t = -b / 2a
Substitute the values of a and b,
t = -2 / (2×(-2)) = 0.5
So the maximum height is reached 0.5 seconds after the stone is thrown.
To find the maximum height, substitute the value of t into the function:
h = -2(0.5)² + 2(0.5) + 40 = 40.5 meters
Therefore, the maximum height reached by each stone is 40.5 meters.

A riverboat travels 54 km downstream in 2 hours. It travels 57 km upstream in 3 hours. Find the speed of the boat and the speed of the stream
Answers
Here we must write and solve a system of equations to find the speed of the boat and the speed of the stream. We will find that the boat's speed is 23km/h and the river's speed is 4km/h.
First, remember the relation:
Distance = Speed*Time.
Now let's define the variables we will be using:
B = boat's speedR = river's speed.When the boat travels downstream, the total speed of the boat is the speed of the boat plus the speed of the river, and we know that in that case it travels 54km in 2 hours, then:
54km = (B + R)*2h
When the boat travels upstream, we must subtract the speed of the river. In that case, we know that the boat travels 57km in 3 hours, then we have:
57km = (B - R)*3h
Then our system of equations is:
54km = (B + R)*2h
57km = (B - R)*3h
To solve this, first, we need to isolate one of the variables in one of the equations, let's isolate B in the second one:
57km = (B - R)*3h
57km/3h + R = B
19 km/h + R = B
Now we can replace that in the other equation:
54km = (B + R)*2h
54km/2h = B + R
27 km/h = B + R = (19 km/h + R) + R
Now we can solve this for R:
27 km/h = 19km/h + 2*R
27 km/h - 19km/h = 2*R
8 km/h = 2*R
(8km/h)/2 = 4km/h = R
Now that we know the value of R, we can use:
B = 19 km/h + R = 19 km/h + 4km/h = 23 km/h
So the boat's speed is 23km/h and the river's speed is 4km/h.

Let be "a", "b" and "c" the addends and "d" the sum. Then:
\(\begin{gathered} a+b+c=d \\ b+c+a=d \end{gathered}\)For example, applying this property, you know that:

What is the vertex of the parabola represented by y = - x^2 + 6x - 5-x has a variable of 2
Answers
Answer:
The vertex of the parabola is (3, 4)
Explanation:
Given the equation:
\(y=-x^2+6x-5\)This is in the form:
\(y=ax^2+bx+c\)With a = -1, b = 6, and c = -5
The x-coordinate of the vertex is given as:
\(\begin{gathered} x=-\frac{b}{2a} \\ \\ =-\frac{6}{2(-1)} \\ \\ =\frac{6}{2} \\ \\ =3 \end{gathered}\)Substituting x by 3 in the equation of the parabola, we can obtain the y-coordinate of the vertex.
Doing that, we have:
\(\begin{gathered} y=-(3^2)+6(3)-5 \\ =-9+18-5 \\ =4 \end{gathered}\)Therefore, the vertex of the parabola is (3, 4)

what do you add to 35 over 8 to make 6
Answers
Answer:
You would add \(\frac{13}{8}\) or 13/8 (fraction)
Step-by-step explanation:
First we make an equation with the following evidence:
We know 35 over 8 is \(\frac{35}{8}\)
And we know were trying to get 6
The unknown is the "add" which gives us X
Equation: x + \(\frac{35}{8}\) = 6
When we solve the equation we get x = 13/8
How do we solve it?
Subtract 35/8 on both sides:
x + 35/8 -35/8 = 6 - 38/8
And leaves us with x = 6

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
Answers
a) The projectile cannot reach a height of 160 feet under given conditions.
b) The projectile takes a time of 2 second to hit the ground.
How to analyze the height of a projectile in time
In this question we find the case of a project under free fall, that is, a vertical uniformly accelerated motion due to action of gravity, whose formula is shown below:
s = - 16 · t² + v₀ · t
Where:
t - Time, in secondsv₀ - Initial speed, in feet per second.Part A - If we know that v₀ = 32 ft / s and s = 160 ft, then the time associated is:
- 16 · t² + v₀ · t - s = 0
- 16 · t² + 32 · t - 160 = 0
By quadratic formula:
t₁ = 1 + i 3, t₂ = 1 - i 3
It is physically impossible to reach a height of 160 feet under conditions given.
Part B - If we know that s = 0 ft and v = 32 ft / s, then the final time is:
- 16 · t² + v₀ · t - s = 0
- 16 · t² + 32 · t = 0
- 16 · t · (t - 2) = 0
The final time for the projectile is 2 seconds.

Step-by-step explanation:
7 is a prime number. Nothing but 1 and 7 divide into which means that twelve and 7 have no highest common factor but 1.
The lowest common multiply (because 12 and 7 are prime to each other ) is 12 * 7 = 84
Answer:
LCM = 84 GCF = 1
Step-by-step explanation:
LCM of 7 and 12 is 84.
GCF(7,12) = 1
LCM(7,12) = ( 7 × 12) / 1
LCM(7,12) = 84 / 1
LCM(7,12) = 84
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
GCF of 7 and 12 is 1. Now calculate the prime factors of 7 and 12, then find the greatest common factor (greatest common divisor) of the numbers.
To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.

How many ways can Patricia choose 4 pizza toppings from a menu of 8 toppings if each topping can only be chosen once
Answers
Answer: 70
======================================================
Explanation:
Consider we have four slots A, B, C, D.
We have 8 choices for slot A, 7 for B, 6 for C, and 5 for D.
We count down because each time we can't reuse whatever topping was picked earlier.
Multiplying out those values gives: 8*7*6*5 = 1680
There are 1680 permutations. This would be the answer if order mattered, but it doesn't matter.
Since order doesn't matter, we have to divide by 4! = 4*3*2*1 = 24. This is the number of ways to arrange any group of 4 items.
We get 1680/24 = 70 as the final answer
--------------------
Another way to get the answer is to apply the nCr combination formula
\(_nC_r = \frac{n!}{r!*(n-r)!}\)
with n = 8 and r = 4.
Another alternative is to use Pascal's Triangle. You would look in the row that starts with 1,8,... and count out 5 slots (because r starts at r = 0) to arrive at 70.
