Find x and y with ray theorem

Answer:

- 2.18

Step-by-step explanation:

550 × [tex]3^{x}[/tex] = 50

[tex]3^{x}[/tex] = [tex]\frac{1}{11}[/tex]

[tex]log_{3}[/tex] [tex]\frac{1}{11}[/tex] = x

x = [tex]log_{3}[/tex] 1 - [tex]log_{3}[/tex] 11

[tex]log_{3}[/tex] 1 = 0

[tex]log_{3}[/tex] 11 = 2.1826583386

x ≈ - 2.18

Answer:

50

Step-by-step explanation:

We know angles in a straight line add up to 180, therefore:

2x + 50 + 30 = 180

2x + 50 = 180 - 30

2x + 50 = 150

2x = 150 - 50 = 100

2x =  100

x = 50

Answer:

Step-by-step explanation: Since we know the angle of a line is 180 degrees. We can use that.

1. 180-30 because we already know that angle is 30 degrees.

2. We are left with 150 degrees so we know the large angle is 150 degrees to check we do this.

3. 150=2x+50

4. 100=2x Divide both sides by two and get

5. x=50

Answer:

1. There are 18 girls

2. (BLANKS IN ORDER) 5, 18, 36, 30

Step-by-step explanation:

with the ratio given, you divide the lager by the smaller then multiply accordingly to the others( keep in mind it depends which number is on what side)

Answer:

It's D. The initial value of y is 3 because 6,9 and 12 are 3 digits apart, and it always is Y over X

Answer:

The percentage change (an increase) wa 40%.

Step-by-step explanation:

The beginning number of acres was 100; adding 40 more brought that to 140 acres.  This was an increase.  Dividing the increase (40) by the starting value (100) yields 0.40.  Finally, multiplying this result by 100% yields 40%.

The percentage change (an increase) wa 40%.

Step-by-step explanation:

There is a total amount of vehicle of 100

which is good because now you can say 73% is cars 16% is small trucks 6% is large trucks and 2% motorcycle and 3% bicycle. Adding the trucks (small 16, large 6) gives us 24% so you can do 100% - 24% and get 74%. Thanks and goodbye!

Answer:

1. Reflection

2. rotation and reflection

3. b', b''

4. 26.3

Step-by-step explanation:

1. It is like looking in a mirror. Its is being reflected across the y axis

2. It is rotated 90 degrees to the right. Then reflected over the x axis.

3. they are the same

4. It is the same as A" B" C" D" so the lengths are the same and you just add them.

2/3 - 1/5

Find the LCM, say, 15

Then we find the multiple in 15

10/15 - 3/15 = 7/15

Answer:  19/8

Step-by-step explanation:

11/4 can be view as 22/8 by multiply 2 to the denominator and numerator.

11/4 - 3/8

= 22/8 - 3/8

= 19/8

Answer:

An algebraic equation is an equation used in algebra which uses numbers and letters. The letters are representing unknown numbers and are called variables.

Answer:

An algebraic equation is "a mathematical statement in which two expressions are set equal to each toher."

If that is too complicated to understand, look at it like this. An algebraic equation usually has two things: an equal sign, and letters. For example, this is an algebraic equation: x + 3 = 7.

Step-by-step explanation:

Answer:

x = -150

Step-by-step explanation:

x/15 = -10

Multiply both sides by 15.

Given:

A figure of a triangle.

To find:

The value of g.

Solution:

Law of Cosines:

[tex]a^2=b^2+c^2-2bccosA[/tex]

Using the Law of Cosines for the given triangle, we get

[tex]g^2=8^2+7^2-2(8)(7)cos(65^\circ)[/tex]

[tex]g^2=64+49-112(0.4226)[/tex]

[tex]g^2=113-47.3312[/tex]

[tex]g^2=65.6688[/tex]

Taking square root on both sides.

[tex]g=\sqrt{65.6688}[/tex]

[tex]g=8.10363[/tex]

[tex]g\approx 8.10[/tex]

Therefore, the value of g is about 8.10 units.

This image shows an example on corresponding angles.

Answer:

Angle 2 and 4

Answer:

1.5

Step-by-step explanation:

First you divide 6 by 4. It looks like this 6/4.

Then you get 1.5 cups of flour.

Good Luck!

Answer:

3/2 cups

Step-by-step explanation:

4 batches = 6 cups

1 batch of cupcakes = (6/4) cups of flour.

hence, 3/2 cups of flour are needed for 1 batch.

Answer:

16[tex]\frac{2}{3}[/tex]%

Step-by-step explanation:

To convert from a fraction to a percentage, you can multiply the fraction by 100%.
