Answer:

since we are not given the value of AC we say that AC =6×10=60

All the area measure units should have square above them.

Hence, option A, C, D is correct.

Answer:

a) c) d)

Step-by-step explanation:

Length is a one-dimensional measure, therefore it is measured in single units.

⇒ m

⇒ cm

⇒ ft

The area of a shape is a two-dimensional quantity (e.g. length × width), therefore it is measured in square units.

⇒ m × m = m²

⇒ cm × cm = cm²

⇒ ft × ft = ft²

The volume of a shape is a three-dimensional quantity (e.g. length × width × height), therefore it is measured in cubic units.

⇒ m × m × m = m³

⇒ cm × cm × cm = cm³

⇒ ft × ft × ft = ft³

Therefore,

Answer:

The positive solution is 1/2

Step-by-step explanation:

(4x+3)(6x-3) = 0

We can use the zero product property to find the zeros

4x+3 =0   6x-3 =0

4x =-3          6x = 3

x = -3/4           x = 3/6

x = -3/4             x = 1/2

The positive solution is 1/2

Answer:

(x +2)² + (y+3)² = 73

Use the distance formula to find radius:

[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

where (x1, y1), (x2, y1) are points

[tex]\rightarrow \sf \sqrt{(-2-1)^2+(-3-5)^2}[/tex]

[tex]\rightarrow \sf \sqrt{73}[/tex]

Eqaution of circle:

(x-h)² + (y-k)² = r²

(x-(-2))² + (y-(-3))² = (√73)²

(x +2)² + (y+3)² = 73

[tex]\huge\boxed{\bf\:tan \: Z= \frac{4}{3}}[/tex]

Step-by-step explanation:

We know that, tan θ = opposite side of ∠θ / adjacent side of ∠θ.

Here, we need to find tan Z,

In this triangle for ∠Z,

Then,

tan Z

= opposite side / adjacent side

= 28 / 21

= 4 / 3

The interval estimate for the true population proportion is 45.25% to 64.75% and we can conclude that the majority of the community supports water rationing

The given parameters are:

The error margin is calculated using:

[tex]E = z * \sqrt{\frac{p* (1 - p)}{n}}[/tex]

Where z is the critical value.

At 95% confidence level, the critical value is:

z = 1.96

So, we have:

[tex]E = 1.96 * \sqrt{\frac{0.55 * (1 - 0.55)}{100}}[/tex]

Evaluate

[tex]E = 1.96 * \sqrt{0.002475}[/tex]

Evaluate

E = 0.0975

Hence, the error margin is 0.0975

This is calculated using:

I = p ± E

So, we have:

I = 0.55 ± 0.0975

Expand

I = (0.55 - 0.0975, 0.55 + 0.0975)

Evaluate

I = (0.4525, 0.6475)

Express as percentage

I = (45.25%, 64.75%)

Hence, the interval estimate for the true population proportion is 45.25% to 64.75%

From the simulation,

The values are approximately the interval estimates.

i.e.

45.25% ≈ 45% and 64.75% ≈ 65%

Hence, we can conclude that the majority of the community supports water rationing

Answer:

the stripe chip design has

the greatest probability of selection

Step-by-step explanation:

p(draw a dot chip) = 1/10

p(draw a star chip) = 2/10

p(draw a heart chip) = 3/10

p(draw a stripe chip) = 4/10

4/10 > 3/10 > 2/10 > 1/10

Therefore , the stripe chip design has

you are so good are this so keeping up

Answer:

(x - 1)(x + 4)

Step-by-step explanation:

What multiplies to (-4) but adds to (3)?

These two values are (4) and (-1). Therefore, these are the values that make up the factored trinomial.

x² + 3x - 4  ----->  (x - 1)(x + 4)

You can check your answer by expanding the factors. This is done by multiplying each term within the first parentheses by each term within the second parentheses.

(x - 1)(x + 4)  ----->  x² - 1x + 4x - 4  ----->  x² + 3x - 4

math

Answer:

where are the limit questions?

a =80 vertically oposite angle

a+b=180 angle of the same side of transversal are 180 degree

so b=180-80

=100

c=b vertically oposite angle

b=100=c

c= 100

Answer:

a=80, b=100, c=100

Step-by-step explanation:

Because A is directly across from 80 degrees, A is also 80 degrees. They are alternate angles, and so they equal the same thing. B is 100, because it is on the same line as 80, and a line equals 180 degrees. C is also 100 degrees, because it is across from B and on the same line as A, which is 80 degrees.

The domain is "all real numbers" which you could type in (-infinity, infinity) or [tex](-\infty, \infty)[/tex] when doing interval notation. This applies to both.

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

Explanation:

See the attached image for the steps of each.

The domain is the set of all real numbers because each result is a polynomial. We don't have to worry about dividing by zero, taking a square root of a negative number etc. There are no restrictions on x. Any real number can replace x to get some real number result for y. This applies to both composite functions.

Answer:

Option B

x ≥ (-5)

Step-by-step explanation:

So,

-3(x + 4) ≥ x + 8

-3x – 12 ≥ x + 8

Add both sides 12 we get,

-3x – 12 + 12 ≥ x + 8 + 12

-3x ≥ x + 20

Similarly, subtract x from both sides we get,

-3x – x ≥ x – x + 20

-4x ≥ 20

Then, divide both sides by (-4) we get,

-4x/(-4) ≥ 20/(-4)

x ≥ -5

Thus, The answer is x ≥ (-5).
