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?

Answers

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

What should be added to both sides of the equation below to complete the square?
x?
+ 6x = -8
O-4
O-2
O-9
09

Answers

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

A rectangle has an area of 270m2.
One of the sides is 3m in length.
Work out the perimeter of the rectangle.

Answers

X * 3 = 270
Solving for x, x = 90

So one side is 90m and the other is 3m.
Now find entire perimeter 90+90+3+3=180+6=186m

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value

Answers

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°

Find the value of x. Round to the nearest tenth.

Use this to find the value of x: tan (x) = 4/3

Answers

Using tan(x) = 4/3

X = arctan(4/3)

X = 53.1 degrees

Answer:

Step-by-step explanation:

tan x = 4/3

tan x=1.333333

divide both sides by tan

x=1.33333/tan

x=tan inverse of 1.33333

x=53.130

x=53.13 to the nearest tenth
