Answer:
The answer is 20 meters squared
base area = side^2 = 2^2 = 4 m^2
base perimeter = (2 x 4) = 8 m
lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2
surface area = (base area + lateral surface) = (4 + 16)= 20m^2
Answer:
x (children) = 58
y (students) = 66
z (adults) = 29
Step-by-step explanation:
Step 1: Write system of equations
x + y + z = 153
5x + 7y + 12z = 1100
1/2x = z
The best way to solve the systems of equations is to use an augmented matrix:
Top row: [1 1 1 | 153]
Middle row: [5 7 12 | 1100]
Bottom row: [1/2 0 -1 | 0]
And then put it in RREF form:
Top row: [1 0 0 | 58]
Middle row: [0 1 0 | 66]
Bottom row: [0 0 1 | 29]
Answer:
[4 + 1] *[7-2] =25
Step-by-step explanation:
[4 + 1] *[7-2] =25
We need to get to 25
What makes 25
5*5
4+1 =5
7-2 =5
5*5 =25
So we need brackets around 4+1 and around 7-2
Answer:
<h2>Check the explanation.</h2>
Step-by-step explanation:
Let, the total population is 1000.
The number of republicans are 26% that is 260, Democrats are 63% that is 630 and Independents are 11% of 1000, that is 110.
20% of 260 = 
Republicans favor some type of corporate tax reform.
51% of 630 = 
.
29% of 110 = 
.
Total number of people, who favor some type of corporate tax is (52 + 321.3 + 31.9) = 404.2 ≅404.
The required probability is 
.
