Answer:
new = 1/3 old = 1/2
new - old = 1/3 - 1/2 = 2/6 - 3/6 = -1/6
dividing by the old: -1/6 divided by 1/2 = -1/6 * 2/1 = -1/3
multiplying by 100% : -100/3 = -33 and 1/3 %
It is a 33 and 1/3 % DECREASE

O-4
O-2
O-9
09
Answer:
Step-by-step explanation:
x² + 6x = 8
Coefficient of the x term: 6
Divide it in half: 3
Square it: 3²
Add 3² to both sides of the equation to complete the square and keep the equation balanced:
x² + 6x + 3² = 8 + 3²
(x+3)² = 17

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride?
Answer:
8
Step-by-step explanation:
You can solve this by creating a linear equation.
Slope: 2.50
Y-intercept: 4.70
y=2.50x+4.70
Since we know that the total fare was 24.70 we can plug it into the y.
24.70=2.50x+4.70
Now solve for the equation.
20=2.50x
8=x
So he went 8 miles with the taxi.
Total number or mile taxi run is 8 miles.
Given that;
Pick up charge = $4.7
Charges per mile = $2.5 per mile
Total fare = $24.7
Find:
Number of mile taxi ride
Computation:
Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]
24.7 = 4.7 + [Total number or mile taxi run][2.5]
[Total number or mile taxi run][2.5] = 24.7 - 4.7
[Total number or mile taxi run][2.5] = 20
Total number or mile taxi run = 20 / 2.5
Total number or mile taxi run = 8 miles

Answer:
x = 6
Step-by-step explanation:
∠ AFB and ∠ EFC are vertically opposite angles and are congruent , then
21x - 9 = 117 ( add 9 to both sides )
21x = 126 ( divide both sides by 21 )
x = 6
The measured valued of x is 6.
What are Vertical Angle?Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines.
We have,
<AFB = 21x- 9
and, <DFC = 27
Using Vertical Angle
<AFB = (<EFD + <DFC)
21x - 9= (90 + 27)
21x - 9 = 117
21x = 117 + 9
21x = 126
x = 6

Find the area of the sector.
44.66 in^2
11.16 in^2
2.8 in^2
50.24 in^2
Answer:
11.16in^2
Step-by-step explanation:
Area of a sector = theta/360 * πr²
Area of a sector = 80/360 * 3.14*4²
Area of a sector = 8/36 * 50.24
Area of a sector = 401.92/36
Area of a sector = 11.16in^2
Hence the Area of the sector is 11.16in^2

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°
The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?
Answer:
42
Step-by-step explanation:
the ratio 2:4 can be reduced to 1:2,
where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.
If there are 14 girls, then there must be 28 boys (14 x 2 = 28).
Now to get the total number we need to add the total number of boys and girls together.
So 14 + 28 = 42
Hope it helps :)
Answer:
32
Step-by-step explanation:
14 + 28 = 32
2 x 7 = 14
4 x 7 = 28
