Find the value of X and Y

Answers

Answer 1

Answer:

x = 30

y = 5

Step-by-step explanation:

Because the top triangle shows 3 congruent angles, we know it's an equilateral.

Therefore 8y = 40

y = 5

______________

Now we have two sides of the triangle: 40 and 80.

The lower left angle of the whole triangle must be 90 degrees because if the hypotenuse is twice the adjacent side, it must be a 30-60-90 triangle.

So, the larger angle containing angle x must be 90 degrees. And because we know that the adjacent angle (equilateral triangle) is 60 degrees, angle x must be 30.

You started the trail with 1400lbs. of food. You now have 1182lbs. of food. What percentage of your starting amount do you have left?

Answers

Answer:

84.5%

Step-by-step explanation:

1400 - 1182 = 218 You are less 218 lbs. of food.

218 ÷ 1400 = 15.5% You are less 15.5% lbs. of food.

100% - 15.5% = 84.5% You have 84.5% lbs if food left.

The Pythagorean Theorem.?

The ratio of men to women in the astronomy club is 3 to 2. The club has
60 members. How many club members are women?

Answers

Plus the two parts if the ratio 3+2 so 5
Divide the 60 members by 5 and get 12
12 is one part of the ratio
12x2 is 24 so 24 woman

24

Because you divide 5 by 60 to find out how much 1 is equal too which is twelve so 1=12 and because there is two for women it’s 12+12 which is 24

2/5 x 5/4 in fraction in its simplest form

Answers

Answer:

The answer is 1/2. When you multiply the numerator and denominator, you get 10/20. If you divide the top and bottom by 5, you get 1/2.

The equivalent value of the fraction is A = 1/2 = 0.5

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = pq

when the value of p = 2/5

And , when the value of q = 5/4

On simplifying the equation , we get

A = ( 2/5 ) ( 5/4 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) ( 5/4 )

A = ( 2/5 ) ( 5/4 )

A = ( 2 x 5 ) / ( 5 x 4 )

On simplifying , we get

A = 10/20

Divide by 10 on the numerator and denominator of the fraction , we get

A = 1/2

A = 0.5

Therefore , the value of A = 1/2 = 0.5

Hence , the fraction is A = 1/2 = 0.5

Two angles of a triangle measure 55 and 20 what is the measure of the third angle of the triangle

Answers

Answer:

105 degrees

Step-by-step explanation:

well if we take a look at this

we know for sure that every triangle must have a total angle measurement of 180 degrees

so if we take the information we have and we add those together

55 + 20

that will give us

then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it

180-75

giving us 105 degrees as the third measurement of the angle in the triangle

Answer:

the third measure is [tex]105[/tex]°

Step-by-step explanation:

All measures of a triangle add up to 180°

[tex]A+ B + C = 180[/tex]

[tex]20 + 55 + C = 180[/tex]

[tex]75 + C = 180[/tex]

[tex]C = 105[/tex]°

I’m not 100% sure but it could be 225 and 328. Adding those together you get a sum of 553.

Hope this helped! Mark me brainliest if you’d like, im tryna get too expert!

x + y = 553

x - y = 225

x + x + 225 = 553

2x = 553 - 225

2x = 328

Divide by 2.

x = 164

164 + y = 553
y - 164 = 225

553 - 164 = 389
225 + 164 = 389

The two mystery numbers are 164 and 389.

Step-by-step explanation:

Given data

aspect ratio of 16: 9

L= 16in

W= 9 in

We want to find the diagonal of the TV

applying Pythagoras theorem

d^2= l^2+w^2

d^2= 16^2+ 9^2

d^2=256+81

d^2= 337

d= √337

d= 18.35 in

Hence the tv is 18.5 in approx

Judy studied for 7/12 hours and her sister studied for 2/3 of a hour about how much time did they studied all together

Answers

So you first need to make both equivalent fractions. You do that by making the denominator the same so you need to find a common multiple between both which is 12 so you multiply 2/3 by 4 on the top and bottom to get something equivalent to 7/12. 7/12 +8/12=15/12 now you divide 15 and 12 to have it in fraction mode you’ll be getting that Judy and her sister studied for 1 hour and 25 minutes

The required time they all together spend time on the study is 1 1/4 hours.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Judy studied for 7/12 hours and her sister studied for 2/3 of an hour
Total time spend on study all together = 7 / 12 + 2 / 3
= 1 1/4 = 1.25 hour

Thus, the required time they all together spend time on the study is 1 1/4 hours.

A bag contains 35 red counters only. Chen adds green counters to the bag. The probability of picking a green counter is now 0.3 How many green counters did Chen add?

Answers

Answer:

Step-by-step explanation:

Red counters = 35

Number of green counters = x

P(picking a green counter) = 0.3

Probability = required outcome / Total possible outcomes

Required outcome = number of green counter

Total possible outcomes = green counter + red counter

Hence,

0.3 = x / (35+x)

0.3(35 + x) = x

10.5 + 0.3x = x

10.5 = x - 0.3x

10.5 = 0.7x

x = 10.5 / 0.7

= 15

Number of green counters = 15
