Mathematics

Answer:

y = 68   because of the equation 2y + (y - 24 ) = 180,  Angle Sum postulate

Step-by-step explanation:

Because line  PQ is a straight line,  we see it measures 180 degrees.

So that means  2y + (y - 24)  =  180 degrees.

Those two angles add up to 180 degrees.

so we can solve this equation for y now.

2y + (y - 24) = 180

3y - 24 = 180

3y = 180 + 24

3y = 204

y = 204/3 = 68

That is how y = 68.

Then the 2*y = 2*68 = 136 degrees.

and  the other angle y - 24 = 68 - 24 = 44 degrees.

If $20.00 is for 12.25kg of peas ...what weight of peas can i get for $4.00​
Alina [70]

2.45kg

First you calculate the price per kg as follows:

If it’s $20 for 12.25 kg, the price per kg is $20/12.25=$1.63 per kg


If you have $4, you can figure out what weight you can get by taking $4/the price per kg, so $4/$1.63, which is 2.45 kg.

Answer:

It is possible for a set of data values to have more than one mode. If there are two data values that occur most frequently, we say that the set of data values is bimodal. If there is no data value or data values that occur most frequently, we say that the set of data values has no mode.

Help please. Having some trouble with this question
xeze [42]

Answer:

The answer to your question is 55 ft

Step-by-step explanation:

Data

Person's height = 5 ft

Person's shadow = 10 ft

Tree's height = ?

Tree's shadow = 110 ft

- Use the Thales' theorem to solve this problem

 Person's height / Person's shadow = Tree's height / Tree's shadow

- Substitution

                     5 / 10 = x / 110

-Solve for x

                     x = 5 (110) / 10

-Simplification

                     x = 550 / 10

-Result

                     x = 55 ft

-Conclusion

The tree is 55 ft height
