A contractor is building a set of stairs out of concrete. Each stair is exactly the same length, width, and height.
Staircase
Diagram shows a set of three steps of a staircase. Height of the third step from the ground measures 1.8 meters. The width from the front of the staircase to the back of the staircase measures 1.2 meters. The length of the steps measures 2.4 meters.
Which solid figures can the stairs be broken into? What are the dimensions of each solid figure?
How much concrete will be needed to form the stairs?
Answer:
Dimensions:
H = 0.9 m
W = 0.4 M
L = 2.4 m
Step-by-step explanation:
As they are all the same dimensions and there are only 3 stairs, divide all the figures (except the length as it will stay the same) by 3 to get your figures.
Answer:
top rectangular prism = .6 x .4 x 2.4
middle rectangular prism = .6 x .8 x 2.4
bottom rectangular prism = .6 x 1.2 x 2.4
concrete needed = 3.672 cubic meters
Step-by-step explanation:
The steps can be broken into bottom step from front to back, middle step from front to back, top step from front to back resulting in
three rectangles
The dimensions of each solid figure can be found since we know the steps are equal so we divide the height and width by 3 equal parts and the length stays the same. So...
1.8/3=.6 m
1.2/3=.4 m
top rectangular prism = .6 x .4 x 2.4
middle rectangular prism = .6 x .8 x 2.4
bottom rectangular prism = .6 x 1.2 x 2.4
Find the volume by plugging our dimensions into the formula for volume for each step and then add all three steps together for total volume...
.6 x .4 x 2.4= .576
.6 x .8 x 2.4= 1.152
.6 x 1.2 x 2.4=1.944
add totals together...
.576 + 1.152 + 1.944=3.672

27q = –513
Solve.
Please
Answer:
-19
Step-by-step explanation:
27x-19=-513
Answer:
-19
Step-by-step explanation:
To solve for q, you need to isolate q. To do, this you would divide both sides by 27.
27q = –513
27q/27 = –513/27
q = -19
The law of large numbers states that, as the number of trials increase, the experimental probability will become closer to an event's -- .
A) outcome
B) probability ratio
C) theoretical probability
D) sample size
The law of large numbers states that as the number of trials or experiments increases, the experimental probability of an event occurring will approach or converge to the theoretical probability of that event.
We have to give that,
The law of large numbers states that, as the number of trials increases, the experimental probability will become closer to an event's
Since we have to know that,
The law of large numbers states that as the number of trials or experiments increases, the experimental probability of an event occurring will approach the theoretical probability of that event.
In other words, the more trials we conduct, the closer our observed outcomes will be to the expected or theoretical outcomes based on probability calculations.
So, the correct option is,
C) Theoretical probability

pls answer the first half of this!
Answer:
$26
Step-by-step explanation:
Mean: [tex]\frac{sum-of-all-the-numbers}{amount-of-numbers}[/tex], which, when added up, equals 154.
154 + 26 would equal 180, and 154 - 26 = 128.
128-180 is well within the range of Q1 and Q3, with the range from 100 to 190
The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?
Answer:
x = 7
Step-by-step explanation:
The 2 angles are adjacent and sum to 180° , that is
11x + 8 + 12x + 11 = 180
23x + 19 = 180 ( subtract 19 from both sides )
23x = 161 ( divide both sides by 23 )
x = 7

let me know if this is wrong
Step-by-step explanation:
first, find the surface area of the square base
6(6)=36
after that, find the surface area of the 4 triangular lateral faces
formula: SA=4(bh÷2)
then substitute
SA=4(6 x 10 ÷ 2)
solve
SA=4(30)
SA=120
add the surface area of the square base and the lateral faces
120+36=156
