Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The angles 2 and 3 are corresponding angles. So it's choice C.
<em><u>Tip:</u></em> Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal.
A = L * W
280 = 14 * A
A = 280 / 14
A = 20
A = 2 tens
Big rectangle: A = 280 + (14 * B)
378 =280 + 14B
14B = 378 - 280
14B = 98
B = 7
So length = 2 tens + 7 = 27
Answer
C. 2 tens + 7 = 27
The interval given was 33% to 37%
This means that subtracting the margin of error from the percentage of the population that visit the library once a year gives the lower end and adding the margin of error to the percentage of the population that visit the library once a year gives the upper end
Let x denote margin of error and y denotes the percentages of the population that visit the library once a year
we can get the following equations and solve for the values of x and y
Adding eqn1 and eqn2 to gives
Putting the value of y into any of the equations
Thus, the margin of error is
Therefore we enter 2 in the box
Answer:
x = 22
Step-by-step explanation:
(x + 3)/25 = 1
Multiply both sides by 25
x + 3 = 25
-3 -3
x = 22

Answer:
4/5
Step-by-step explanation:
<u>Given</u>,
Area of the triangle = 1/4 square meters
From the diagram,
Height = 2/5 m
<u>To find</u> : Length of the base
<u>Formula</u> : -
A = bh/2
Here,
A denotes Area
b denotes Base
h denotes Height
A = 1/4
h = 2/5
A = bh/2
Cross multiply,
A * 2 = bh
2A = bh
2 * (1/4) = b * (2/5)
(1 * 2)/4 = (b * 2)/5
2/4 = 2b/5
1/2 = 2b/5
Cross multiply,
1 * 5 = 2 * 2b
5 = 4b
b = 4/5 meters
Hence,
The length of the base is 4/5 meters.
