Mathematics
1 answer:
artcher [175]3 years ago
6 0

Answer: m∠BCE = 63°

              m∠BAD = 76°

Step-by-step explanation:

Problem 1:

Given

m∠BEC = 90°

m∠EBC = 27°

Total = 117°

Solution:

Subtract 180° - 117° = m∠BCE = 63°

Problem 2:

Given

m∠ADE = 52°

m∠ABE = 52°

Total = 104°

Solution:

Subtract 180° - 104° = m∠BAD = 76°

<h3>Answer:  36%</h3>

============================================

Explanation:

There are 20 blue cards out of 10+20+25 = 55 cards total.

Divide the 20 over 55 to get

20/55 = 0.363636...

where the "36"s go on forever

So 20/55 = 0.3636 approximately

Move the decimal point over 2 spots to go from 0.3637 to 36.37%

Then round to the nearest percent: 36.37% ---> 36%

The probability of getting a blue card is approximately 36%

A circle has an arc of length 56 pie that is intercepted by a central angle of 120°.
Salsk061 [2.6K]

Answer:

Therefore radius is 84 units.

Step-by-step explanation:

Given:

arc length = 56 pie

Central angle = θ = 120°

pi = 3.14

To Find:

Radius = r =?

Solution:

If the θ  measured in degree then the arc length is given as

\textrm{arc length}=\dfrac{\theta}{360\°}\times 2\pi r

Where r = radius, θ = Central angle

On substituting the values we get

56\pi=\dfrac{120}{360}\times 2\pi\times r\\\\r=\dfrac{3\times 56}{2}=84\\\therefore r=84\ unit

Therefore radius is 84 units.

Solve the system of linear equations. Y=-1/6x+5 and x+6y=30 Can you explain the steps?
aleksklad [387]

Answer:

Infinitely many solutions

Step-by-step explanation:

y = -1/6x + 5

x + 6y = 30

We can solve this system by using substitution or elimination. Since we are given an isolated y-value, I'll be using the substitution method.

Substitute y = -1/6x + 5 into the second equation for y.

  • x + 6(-1/6x + 5) = 30

Distribute 6 inside the parentheses.

  • x - x + 30 = 30

Combine like terms.

  • 30 = 30

Since this is a true statement, we can conclude that this system has a solution of all real numbers, or infinitely many solutions.

We can also see that these equations are indeed equivalent by multiplying the top equation by 6.

6 * (y = -1/6x + 5) → 6y = -x + 30

Adding x to both sides and rearranging terms gives us x + 6y = 30, which is the same as the second equation.
