Answer:
Step-by-step explanation:
1).
= 2 : 3
2). 6 : 4 =
=
6 : 4 = 3 : 2
3).
= 1 : 3
4). 12 : 8 =
=
= 3 : 2
And = 3:2
Therefore, 12 : 8 =
5).
= 7 : 4
6). 4 : 10 =
=
Therefore, equivalent ratios are,
a). 2 : 3 =
b). 3 : 2 = 6 to 4
c). = 1 : 3
d). 18 to 12 = 12 to 8
e).
f).
Answer:
Angle a = 17°
Angle b = 17°
Step-by-step explanation:
Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Vertical angles are angles that are equal to each other
Step 1
We find x
a = b
Hence,
8x+1 = 21-2x
Collect like terms
8x + 2x = 21 - 1
10x = 20
x = 20/10
x = 2
Step 2
We find each angle
Angle a
8x+1
x = 2
Angle a = 8(2) + 1
= 17°
Angle b
21-2x
x = 2
21 - (2 × 2)
= 21 - 4
= 17°
Therefore:
Angle a = 17°
Angle b = 17°
<span>Compatible numbers are numbers in a problem that are easy to compute mentally. They are numbers that are close in values to the actual number and this makes it easy to perform mental arithemetics. Compatible numbers can be rounded up to the nearest tens, twenty, etc, in order to make computation easier.</span>
