ABC Is An Isoscles Triangle. Angle A = 40.Find Measure Of Angle B.407075180

Answers

Answer 1

Answer:

70 degrees

Step-by-step explanation:

total angle in a triangle is 180 degrees

180-40= 140

Angle b and c is total of 140 degrees

they are isosceles so their measurements would be same.

angle b and c is 140÷ 2 = 70

so angle b is 70 degrees

Answers

Answer:

4x² + 12x + 9

Use the FOIL method to solve.

FOIL =

Multiply:

(2x)(2x) = 4x²

(2x)(3) = 6x

(3)(2x) = 6x

(3)(3) = 9

Combine like terms:

4x² + 6x + 6x + 9 = 4x² + (6x + 6x) + 9 = 4x² + 12x + 9

4x² + 12x + 9 is your answer.

Answers

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0-2}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]

note the line crosses the y- axis at (0, 2) ⇒ c = 2

y = - [tex]\frac{1}{2}[/tex] x + 2 ← equation of line

Answers

Answer:

Step-by-step explanation:

[tex] = > (2 {x}^{6} + 8 {x}^{2} - x + 1) + (3 {x}^{6} + 5 {x}^{5} + 1) \\ \\ = > 2 {x}^{6} + 8 {x}^{2} - x + 1 + 3 {x}^{6} + 5 {x}^{5} + 1 \\ \\ = > 2 {x}^{6} + 3 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 1 + 1 \\ \\ = > 5 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 2[/tex]

The polynomial representing the sum is [tex]5x^6 + 5x^5 + 8x^2 - x + 2[/tex] (Option B).

The polynomial that represents the sum of the two polynomials is:

[tex](2x^6 + 8x^2 - x + 1) + (3x^6 + 5x^5 + 1)[/tex]

Combining like terms, we can simplify the expression:

[tex]2x^6 + 3x^6 + 8x^2 + 5x^5 - x + 1 + 1[/tex]

Now, combining the like terms further:

[tex]5x^6 + 5x^5 + 8x^2 - x + 2[/tex]

Therefore, the polynomial that represents the sum is:

The probability of a chance event is 0.8, it is __________ to happen when compared to a chance event with a probability of 0.9. Select one: equally likely less likely more likely both more and less likely

Answers

Answer:

less likely

Step-by-step explanation:

In the question, we are to choose which of the options best fit into blank space.

Talking about probabilities, the probability of events ranges from 0 to 1. With 1 being the highest value the probability of an event can take while 0 is the lowest value the probability of an event can take. The probability of an event can neither be negative, nor greater than 1. It lies between 0 and 1

Now, the closer a probability is to 1, the greater the likelihood of that particular event happening. Events having probabilities closer to 1 are more likely to occur than those farther away from 1 or closer to zero.

In this question, 0.9 is a greater value compared to 0.8. Thus, an event of probability 0.9 is more likely to happen compared with an event with probability of 0.8

In other words, an event with probability 0.8 is less likely to occur compared with an event with a probability value of 0.9

A Web music store offers two versions of a popular song. The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.4 MB. Yesterday, there were 950 downloads of the song, for a total download size of 3284 MB. How many downloads of the standard version were there?

Number of standard version downloads: ?

Answers

Answer:

560 downloads of standard version downloads.

Step-by-step explanation:

Let there were number of standard version of downloads = x

and number of high quality version of downloads = y

There were total 950 downloads of the both type of songs.

x + y = 950 -----(1)

Size of the standard version songs = 2.8 MB

and the size of the high quality version songs = 4.4 MB

Total download size = 3284 MB

2.8x + 4.4y = 3284

7x + 11y = 8210 -----(2)

Multiply equation (1) by 11 (-) equation (2)

(11x + 11y) - (7x + 11y) = 10450 - 8210

4x = 2240

x = 560

There were 560 downloads of the standard version downloads.

Answer:

x is 60°

y is 30°

(would really, reallly appreciate the brainliest)

Step-by-step explanation:

x can be seen as what's needed to do a full 180 ° turn when you already turned 120°

y is 60° bc the sum of all tree angles of a triangle is always 180°

90° are given with the little square, 60 by the similar reasoning as above

Answer:

Step-by-step explanation:

L an M are parallel & P is transversal.

So, 120, x are co-interior angles, ie 180

x +120 = 180

x = 180 - 120

x = 60

The angle  vertically opposite to x, will have the same value of x.

Vertically opposite angles are equal

In triangle, sum of angles = 180

60 + 90 + y = 180

150 + y =180

y =180 -  150

y =30

Chris achieved these scores in his exams. What was his best result?

a) 34 of 60 for history
b) 29 of 50 for science
c) 39 of 70 for Music
d) 44 of 80 for Math

Answers

Answer:

b) 29 of 50 for science

Step-by-step explanation:

We would be finding out his best results by calculating the percentage of his scores in the various exams he took.

a) 34 of 60 for history

34/ 60 × 100 = 56.67%

b) 29 of 50 for science

29/50 × 100 = 58%

c) 39 of 70 for Music

39/70 × 100 = 55.7%

d) 44 of 80 for Math

44/80 × 100 = 55%

Looking at the percentage of his scores in various subject in his exams, the subject with the highest percentage is the subject where he had the best result.

That subject with 58% = 29/50 for science.

Therefore, his best results is option b) 29 of 50 for science.

A stone fell from the top of a cliff into the ocean.
In the air, it had an average speed of 16. In the water, it had an average speed of 3 before hitting the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire fall took 12 seconds.
How long did the stone fall in the air and how long did it fall in the water?

Answers

Answer:

5 seconds.

Step-by-step explanation:

Make an equation.

Time in air = x

Time in water = 12 - x

16x + 36 - 3x = 127

13x = 91

x = 7

12 - 7 = 5

A bank account has a beginning balance of $560.00. After 6 months, the balance in the account has increased to $572.60. What interest rate is being earned annually on this account?
2.20%

2.25%
4.5%

Answers

Answer:

D. 4.5%.

Step-by-step explanation:

Interest earned in 6 months = 572.6 - 560 = $12.60.

As a percentage this is (12.60 * 100) / 560

= $ 2.25%.

So the annual interest is 2 * 2.25

= 4.5%.
