Answer:
yes, AA
Step-by-step explanation:
since both have 90 degree angles, and 62+28 is also 90, all 3 sets of angles are congruent
18 miles = 30 minutes
? miles = 10 minutes
cross multiply
? x 30 = 18 x 10 (180)
? = 180/30
? = 6
the city bus would cover 6 miles in 10 minutes.
Step-by-step explanation:
Area of the circle = pi×r²
= 22/7 × 6 × 6
= 113.14 unit²
The product is 
Explanation:
The given expression is 
We need to determine the product of the given expression.
First, we shall simplify the given expression.
Thus, we have,


Expanding the expression, we have,

Now, we shall apply FOIL, we get,

Simplifying the terms, we have,

Multiplying, we get,

Adding the like terms, we get,

Thus, the product of the given expression is 
Answer:
Step-by-step explanation:
1) Least common denominator of 4 and 2 is 4
To eliminate the fraction, each term should be multiplied by 4
ANS:option c
2) Mercury level of water 'y' years = Initial measure +rate of increase 'y' years
0.05 +0.1y = 0.12+0.06y
Ans : Option c
3) 4b +6 = 2 - b + 4
Add 'b' to both sides
4b + b + 6 = 2 + 4
5b + 6 = 6
Subtract 6 from both sides
5b = 6 - 6
5b = 0
b = 0
Ans : Option b
4) Maximum decimal places in this equation is 2. So, to eliminate decimal places, The equation should be multiplied by 100
Ans: option d
5) y +6 = -3y + 26
Add 3y to both the sides
y + 6 + 3y = 26
y + 3y + 6 = 26
4y + 6 = 26
Subtract 6 from both sides
4y = 26-6
4y = 20
Divide bothe sides by 4
y = 20/4
y = 5
Ans: option c
6) '2x' is subtracted from both side of the equation.
Ans: option a - subtraction property of equality
