Answer:

y = 55°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

100° is an exterior angle of the triangle , then

y + 45° = 100° ( subtract 45° from both sides )

y = 55°

Answer:

Step-by-step explanation:

According to the question, the correct graph is D.

It's not A because, the ball is thrown after some pause and the ball doesn't roll on the roof, falls immediately.

It's not B or C because the ball goes up after reaching the roof but should fall down.

1 is the answer

Step-by-step explanation:

Number of possible outcomes = 10

Total number of outcome = 10

Probability = [tex] \frac{Number \: of \: possible \: outcomes}{Total \: number \: of \: outcome}[/tex]

[tex] = > \frac{10}{10}[/tex]

[tex] = > 1[/tex]

Hence, the probability of finding number less than or equal to 10 is [tex]1[/tex]

Answer:

a.  median 1.5

Step-by-step explanation:

If you sort the numbers from least to greatest, the middle numbers are 1 and 2, so the median is the middle of those, 1.5. And the mean is 2.75, so it can't be the others.

Answer:  1/11

Step-by-step explanation:

The probability that the selected piece will be red velvet is equal to the amount of red velvet cake divided by the total amount of cake.

Therefore, it would be 3/(25+1+2+3+2)

= 3/33

= 1/11 when simplified

Answer:

So the answer is that 5 3/10 as a decimal is 5.3. 9/10 as a decimal is expressed as 0.9.

Step-by-step explanation:

To convert any fraction to its decimal form, we just need to divide the numerator by the denominator.

In this case, we divide 9 by 10, 9 ÷ 10 = 0.9

Answer:

slope: 2 as we see, with every increase in x, y increase twice the more.

Step-by-step explanation:

The slope of the linear graph in the question obtained using the ratio of the rise and run of the line is 2.

Recall :

Slope = Rise / Run

From the graph :

Rise = y2 - y1 = 5 - (-1) = 5 + 1 = 6

Run = x2 - x1 = 2 - (-1) = 2 + 1 = 3

The slope of the graph can be expressed thus :

Slope = Rise / Run = 6 /3 = 2

Therefore, the slope of the line in the graph attached is 2

Answer:

exact value is 264π and decimal to the thousandths is 829.381m²

Step-by-step explanation:

It gives you the formula.

(pi times 8 times 25) + (pi times 8 squared)

Answer:

A≈829.38

A= pi x 8 x 25 + (pi x 8^2)

A= 200pi + 64 pi

A= 264pi

Answer is 264

Answer: it's 31.3 percent.

Step-by-step explanation:

55 feet of 80 is 68 percent, to find the remainder you need to subtract 68 by 100, and with that, you get 31.3 percent.

if you want that in feet it's about 25 feet

Answer:

0

Step-by-step explanation:

Since displacement is the distance between the journey starting point and the final point if they both are the same the difference becomes zero and hence the displacement.

Displacement = final point - initial point

(both are same)

= same - same

= 0

Answer:

Step-by-step explanation:

The exact value for the expression √52 – √13 + √117 given in the question above is 4√13

a√b + c√b = (a + c)√b

With the above information in mind, we can simplify the express given in the question above.

√52 – √13 + √117

Recall

√52 = √(4 × 13) = 2√13

√117 = √(9 × 13) = 3√13

Thus

√52 – √13 + √117 = 2√13 – √13 + 3√13

√52 – √13 + √117 = (2 – 1 + 3)√13

√52 – √13 + √117 = 4√13

The equation which shows the true solution to the given logarithmic equation is,

[tex]x=1[/tex]

The power of the log rule says that the number written in the front of the logarithmic function can be raised to the power of the logarithmic function.

For example,

[tex]n\log_b(M)=\log_b(M)^n[/tex]

Given information-

The logarithmic equation given in the problem is,

[tex]3\log_2(2x)=3[/tex]

Using the power rule of the logarithmic function,

[tex]\log_2(2x)^3=3[/tex]

Using the exponent rule of the logarithmic function the above equation can be written as,

[tex](2x)^3=3[/tex]

Solve it further,

(-1, 3) 2 units up = +2y = 5

(1, 5) A rotation of 90° counterclockwise around the origin can be described in mathematical terms as (x, y) → (−y, x).

(1, 5) → (-5, 1), or C

Answer:

B. (-5, -1)

Step-by-step explanation:

Since we're solving for A :

A (-4, 3) translated 3 units to the right and 2 units up would be A (-4 + 3, 3 + 2), which is A' (-1, 5). Then, we have to rotate it 90 degrees clockwise. This would be (-5, -1), as the formula states (x, y) -> (-y, x), which means the x stays the same but goes to the 'y' position, and the y sign changes and goes to the 'x' position.

So, it would be (-5, -1) :)

anyways, hope this helped! :)

Answer:

[tex]4x^2y-7xy+10xy^2[/tex]

Step-by-step explanation:

We have [tex]\left(6x^2y-8xy+7xy^2\right)+\left(3xy^2-2x^2y+xy\right)[/tex] and need to add them together.

Though complicated at first, we can simplify by taking out the parenthesis and making this whole question into one equation.

[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]

Now combine like terms, meaning you can only add the terms that have the same ending, in math, you cannot add numbers that have different exponents or variables.

Therefore:

[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]

[tex]6x^2y-2x^2y-8xy+xy+7xy^2+3xy^2[/tex]

[tex]4x^2y-7xy+10xy^2[/tex]
