Step-by-step explanation:
find surface area of the square pyramid!!! pls i need help with explaining!!!!!
Answer:
39 square yards
Step-by-step explanation:
The base is a square, so the area is 3 x 3 = 9.
Each side is a triangle, and the formula for that is (1/2)(base)(height)
The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30
Add the base and sides
30 + 9 = 39
Answer:
39 yards
Step-by-step explanation:
surface area = A + [tex]\frac{1}{2}[/tex] ps
A = area of the base
p = perimeter of the base
s = slant height
the base of the pyramid is a square, all sides and angles are equal
; 3 yards
; area of a square = l x w
; area of the base = 9 yd (A)
perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)
slant height = 5 yd (s)
; sub it into the formula
surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5
surface area = 39 yd
What is the perimeter of the triangle?
Answer:
p=a+b+c
sode+base+side

-I'll give branliest as a reward-
Answer:
AC=2.868
Step-by-step explanation:
using pythagoras theorem
take 35 degree as reference angle
hypotenuse =5 , opposite =AC , adjacent=BC
using sin rule
sin 35=opposite/hypotenuse
0.5735=AC/5
0.5735*5=AC
2.8675=AC
2.868=AC

Answer: The answer to Number 4 is 1!
Step-by-step explanation:
First you solve for the numbers in parentheses. 16 - 7 is 9, and 2 x 4 is 8. Then you solve for the remaining numbers. So 9 - 8 is indeed 1.
Hope this helps! :)
Answer:
The answer to number 2 is 1
Step-by-step explanation:
[tex] \frac{1}{5} \times 5 = \frac{1}{5} \times \frac{5}{1} \\ \\ \frac{5 \times 1}{5 \times 1 } = \frac{5}{5} = \frac{1}{1} = 1[/tex]
Find the measure of each of the following
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
Solve the following equation.
U + 2 = 4
Answer:
U=2
Step-by-step explanation:
This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.
The Smith family have decided to build a uniform walkway that is 3 ft wide using Travertine pavers around their rectangular swimming pool which measures 16 ft by 24 ft.
What is the area of the walkway? - 384 ft sq.
The paver selected by the family measures 6 in by 12 in. How many pavers are needed to cover the walkway?
Answer:
not sure
Step-by-step explanation:
6*12=72, 72in to feet is 6ft
384/6=64ft
Answer:
384 divided by 72 (6 times 12) = 5.33 i think
Find the volume of this prism.
PLEASE HELP ASAP!
Consider the 720 permutations of the numbers 1, 2, 3, 4, 5, 6. In how many of these permutations do exactly 3 of the numbers end up in the positions where they started?
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with 2.
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.

Find the value of x please.
Answer:
83
Step-by-step explanation:
its a guess bc its a right triangle and right triangle is 90 degrees minus 7 is 83
Answer:
I think it is 93 degrees
Step-by-step explanation:
A triangle has a full angle of 180 degrees
47+47 = 94
180-94=86
x-7=86
x = 93

Can you plzz find the width...and give steps
Answer:
12
Step-by-step explanation:
We know that Tyler's chest has a length of 30 inches, width of 16, and a height of 24 inches. To find the volume of the chest, multiply the length by width by height: 24*30*16 = 11,520 in^3 The volume is 11,520.
Juliet's chest will Have a length of 40 inches and the same height as Tyler's chest, or 24 inches. It also has the same volume of Tyler's chest, or 11,520
So Tyler's chest is 24 by 30 by 16 inches, and is 11,520 inches^3
Juliet's chest will be 40 by ? by 24 inches, and will be 11,520 inches^2.
We have to find the width of Juliet's chest. To do that, we have to divide the length times height of Juliet's chest by The volume of her chest, or
11,520/(40*24) = 11,520/960 = 12
Her chest is 12 inches wide

How much fabric did Daria use to make this number cube?
which angles are adjacent to 12 ? select all that apply
helpppp plzzz...plz give steps
Answer:
Volume of hemisphere =
[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]
Given volume =
[tex]18\pi \: cube[/tex]
[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]
So pi is there on both the sides so it will be cut from both LHS and RHS
[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]
[tex]2 \times r {}^{3 } = 18 \times 3[/tex]
[tex]2 \times r {}^{3} = 54[/tex]
[tex]r {}^{3} = \frac{54}{2} [/tex]
[tex]r {}^{3} = 27[/tex]
[tex]r = 3[/tex]
Therefore value of r=3 inches

Hey PLZZZZ HELP!
The profits earned in a year by some companies in a city are shown below: Company Profit A $160,000 B $140,000 C $130,000 D $1,120,000 E $150,000 Based on the data, should the mean or the median be used to make an inference about the profits earned by these companies? Mean, because it is in the center of the data Median, because it is in the center of the data Mean, because there are no outliers that affect the mean Median, because there is an outlier that affects the mean
Answer:
mean because there is an outlier
Step-by-step explanation:
since there is an outlier that affected the mean which is company D, it can only be mean because the outlier is too big.

Answer: ∠1 and ∠5
Step-by-step explanation:
You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

im very confused on this please help me:)
The constant rate of change is how much y increases every time x increases by 1. We might be confused because in this table, we see a number of points, but we don't see any consecutive x-values, so it might seem difficult. But no worries!
All you have to do is calculate using the formula, Δy divided by Δx. What does Δy divided by Δx mean?
All we have to do is look at two points. Let's take, for example, (-2, -10) and (2, -8).
-2 and 2 are the x-values of the points and -10 and -8 are the y-values of the points as coordinates are in the format of (x, y).
All we have to do is minus the y-coordinates and then proceed the minus the x-coordinates. The order does not matter, as in you can do either of these ways:
[(-10) - (-8)] ÷ [(-2) - (2)] = -2 / -4 = 1/2
or
[(-8) - (-10)] ÷ [(2) - (-2)] = 2 / 4 = 1/2
So the constant rate of change or the answer is 1/2.
