Give step by step instructions and the final answer on how to find the volume of a right square pyramid who has a slant height of 5 inches and the length of the base is 4 inches.
To earn full points you must :
- Show each step of your work
- Keep it organized and easy to read
- Give a brief explanation of why you perform each step
- give the correct final answer
Answer:
Below.
Step-by-step explanation:
First find the perpendicular height of the pyramid.
The median of one of the faces, the height and and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:
5^2 = 2^2 + h^2
h^2 = 5^2 - 2^2 = 21
h = √21 inches.
The volume of the pyramid V = 1/3 * h * area of the base, so
V = 1/3 * 4^2 * √21
= 24.44 in^3 to nearest hundredth.
The volume of a right square pyramid will be (16√21) / 3 cubic units.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.
Then the volume of the pyramid will be
Volume = (1/3) × A × h
The slant height is given as.
l² = (half of side)² + h²
A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.
Then the height of the pyramid will be
5² = (4/2)² + h²
h² = 25 - 4
h = √21 inches
Then the volume of a right square pyramid will be
Volume = (1/3) × 4 × 4 × √21
Volume = (16√21) / 3
Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.

In right triangle XYZ, angle Y is a right angle. What is the relationship between angles X and Z? What is the relationship between sin X and cos Z?
a) Angles X and Z are supplementary, and sin X= cos Z
b) Angles X and Z are complementary, and sin X= cos Z
c) Angles X and Z are supplementary, and sin X= 1 - cos Z
d) Angles X and Z are complementary, and sin X= 1 - cos Z
Answer:
B
Step-by-step explanation:
The angles of X and Z are supplementary and sinX and cosZ will be the same hence, option (b) will be correct.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
Given that in triangle Y is 90° since in any triangle sum of all three angles will be 180° so remaining angle Z and Y will be total of 90° hence these will be complementary.
In right angle triangle sinX = cosZ because the perpendicular for X act like a base for Y.

tamika has $55 in her savings account. She plans on depostiting $5 per week into her account. Write and solve an inqequality to find out how many weeks she must save to have more than $100 in her account. Then interpet the solution
Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
55+5x>1005x>100-55 (Subtract 55 from each side)5x>45x>9 (Divide each side by 5)This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.

Answer:
First option: 336
Step-by-step explanation:
To find the answer, separately solve for each of the shapes.
1. The base is the square so length times width is the formula:
12 x 12 = 144
144 is the area of the square
Next, find the 4 triangles which are congruent(the same).
Triangle area formula: Base x Height divided by 2.
So, the area of 1 triangle is 12 x 8 =96
96/2 = 48
Area =48
Because there are 4 triangles, do 48 x 4=192.
Finally, add the area together and you should get 192+144 =336 ft^2
Surface area = 336 ft^2

We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.
Hope this helped!

On a certain hot summer's day, 540 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $822.75. How many children and how many adults swam at the public pool that day?
Answer:
There were 343 children and 197 adults.
Step-by-step explanation:
In order to solve this problem, you can use an equation after identifying the important information, like that there were 540 people, the cost for a child is $1.25, the cost for an adult is $2.00, and admission fees totaled $822.75:
where c = number of children, and a = number of adults,
c + a = 540
1.25c + 2a = 822.75
Now, you need to solve this system of equations by isolating one of the variables. I'll isolate c by multiplying the first equation by 2 since it's easier:
2c + 2a = 1080
- 1.25c + 2a = 822.75
= .75c = 257.25
Now, you can multiply both sides by 4/3 to find c:
c = 257.25 × 4 ÷ 3
c = 343
So there were 343 children. Now you can find the number of adults by substituting 343 for c in the first equation:
where c + a = 540 and c = 343,
343 + a = 540
a = 197
So, there were 197 adults.

Suppose that 29\%29%29, percent of undergraduates at a large university are involved in a campus organization. The administration plans to take an SRS of 100100100 undergraduates from the population of over 20{,}00020,00020, comma, 000 undergraduate students at the school to see what proportion of students sampled are involved in a campus organization.
Answer:
μ p ^ =0.29
σ p ^ = Square root[ ( (0.29)(0.71) )/100 ]
Step-by-step explanation:
The mean of the sampling distribution of a sample proportion is equal to the population proportion.
μ p ^ =p
The population proportion reported is 29%, so p=0.29p.
\mu_{\hat p}=p=0.29μ
μ p ^ = 0.29
Since σ p hat = sqare root [ ( p(1-p) )/ n]
After subsitution we get σ p ^ = Square root[ ( (0.29)(0.71) )/100 ]

Answer:
Step-by-step explanation:
r=4, w=3, b=2, g=1, t=(4+3+2+1)=10
9) P(r or g)=4/10+1/10=5/10= 1/2
10) P(r or b)=4/10+2/10=6/10= 3/5
11) P(!b)=P(r or w or g)=4/10+3/10+1/10=8/10= 4/5
12) There are six numbers and only one six, P(6)= 1/6
13) The only even numbers less than 5 are 2 and four so
P(e<5)=2/6= 1/3
14) The primes on a die are 2,3,5 so three primes out of six numbers
P(!)=3/6= 1/2
15) 2,3,4,6 are multiples of 2 and three
P(2n or 3n)=4/6= 2/3
16) We want a one half probability so
P(W)=(3+x)/(3+4+2+x)=1/2
(3+x)/(9+x)=1/2
2(3+x)=9+x
6+2x=9+x
x=3
So 3 white marbles have to be added.
17) (3+x)/(9+x)=2/3
3(3+x)=2(9+x)
9+3x=18+2x
x=9
So nine whites need to be added.

Bilal and Charlie have some sweets. Bilal has 4 times as many sweets as Charlie. Bilal gives Charlie 15 of his sweets and now they have the same amount. How many sweets do they have altogether?
Answer:
50
Step-by-step explanation:
The computation of the number of sweets they do have altogether is as follows:
Let us assume Charlie sweets be x
So bilal sweets is 4x
Now Bilal gives Charlie 15 of his sweets due to which they must have the same amount
4x - 15 = x + 15
4x -x = 15 + 15
3x = 30
x = 10 = Charlie sweets
Bilal sweets = 4x = 4(10) = 40
So the total no of sweets held by them is 50
