Answer:
Ratios describe proportions. We can always multiply across ratios, or divide across them (as long as we do it to all of them). For example, the ratio 3 : 2 is the same as 6 : 4 and 300 : 200. Accuracy Tip.

Answer:
-69/200
Step-by-step explanation:
-0.345 is in decimal form.
In Fractional form (p/q)
=-345/1000
To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.
In this case,G.C.D of 345 and 1000 is 5.
Simplified form=-69/200 [ANS]
First question’s answer:
Since angle A = Angle E
Therefore, Angle B (=x) = Angle D
B = X
D = 66
By replacement B = X = D = 66
So, B = 66
Answer is (A)
-------------
Second question’s answer:
Since Angle F = 63 & Angle C = (3X + 3)
Therefore, Angle F = Angle C
63 = (3X + 3)
Add (-3) into each side
63 + (-3) = (3X + 3) -3
3x + -3x = 0
63 + -3x = 3 + 0
63 + -3x = 3
Now, Add '-63' to each side of the equation
63 + -63 + -3x = 3 + -63
63 + -63 = 0
0 + -3x = 3 + -63
-3x = 3 + -63
3 + -63 = -60
-3x = -60
Divide each side by '-3'
x = 20
So, X angle value is 20 (X=20)
The answer is (C)
Good luck!
Answer:
7.99- no
8.162- no
8.074- yes
8.13- yes
8.012- no
Step-by-step explanation:
7.99 to the nearest tenth = 8.0
8.162 to the nearest tenth= 8.2
8.074 to the nearest tenth=8.1
8.13 to the nearest tenth=8.1
8.012 to the nearest tenth=8.0
When rounding to the nearest tenth look at the place after it. If it is less than five then the number in the tenth will be rounded to 0. However if the following digit is 5 and above, 1 is added to the number you are rounding.
