Find the measures of the interior angles.

Answers

Answer:

The two angles are 39°

Step-by-step explanation:

180 - 102 = 78. 78/2 = 39.

Answer:

x=39

Step-by-step explanation:

We know that three angles combine has equal 180 degrees.

180-102=78

78/2=39

I subtracted 102 from 180 to know the degrees of the rest of the two angles combine, then divide the 78 by 2 to find the angles of the individual angles.

10^-2 + 8 round the coefficient to two decimal places

Answers

Answer:

I believe it is .0801

Step-by-step explanation:

- A negative exponent will always turn into a fraction

- First change it to a fraction

1/10^2

- Simplify the exponent

10 times 10 = 100

- Change the fraction

1/100 or in decimal form which is 0.01

- Now the addition

8 + 0.01 = 8.01

- Move decimal to two decimal places

.0801

Answer: .0801 is what I got because the way I understand it 10^(-2) + 8 =8.01 and you said round it to the coefficient to 2 decimal places. so I moves the 8 over 2 times because 8 is the coefficient and I got .0801

Hope it helped and I got it right

What are the domain and range of f(x) = 21?

Answers

The domain and the range of a function, are the set of values the function can take as input and output.

The domain and the range of [tex]\mathbf{f(x) = 21}[/tex] are:[tex]\mathbf{(-\infty,\infty)}[/tex] and 21, respectively.

The function is given as:

[tex]\mathbf{f(x) = 21}[/tex]

There is no restriction as to the value of x.

So, the domain is:

[tex]\mathbf{Domain = (-\infty,\infty)}[/tex]

Irrespective of what the value of x is, the value of y will remain 21.

So, the range is;

[tex]\mathbf{Range = 21}[/tex]

Hence, the domain and the range of [tex]\mathbf{f(x) = 21}[/tex] are:[tex]\mathbf{(-\infty,\infty)}[/tex] and 21, respectively.

the area of a base of a cylindrical water tank is 12π square feet. the volume of water in the tank is dependent on the height of the water (h) and is represented by the function V(h) = 12π h
part a - find V to the power of -1 (h)
part b - what will the height of the water be when the volume reacher 420π cubic feet

Answers

Answer:

Step-by-step explanation:

V^－1(h)is find inverse function=h / 12π

V=12πh=420π

h=420π/12π=35 feet

The inverse of the function V(h) is V⁻¹(h) = h / (12π). And the height of the water is 35 feet.

What is the volume of a right circular cylinder?

Let r be the radius and h be the height of the cylinder. Then the volume of the cylinder will be given as,

V = π r²h cubic units

A cylindrical water tank's base measures 12π square feet. The volume of water in the tank is proportional to its height (h) and is represented by the function V(h) = 12π h.

The inverse of the function V(h) is given as,

h = 12π V⁻¹(h)

V⁻¹(h) = h / (12π)

If the volume is 420π cubic feet. Then the height of the water is given as,

420π = 12π h

h = 420π / 12π

h = 35 feet

The inverse of the function V(h) is V⁻¹(h) = h / (12π). And the height of the water is 35 feet.

Due to global warming, over a 20-year period, many birds have extended the northern margins of
their ranges by an average of about 12 miles. Assuming global warming continues at the same
rate, by how many miles will they have extended their range in another 10 years?

Answers

I’m pretty sure it’s 16 miles.
12 divided by 2 is 6
So in another 10 years, they would have extended their range by 6 more miles in 10 years.
So 30 years would be 16 miles.

In a hand of playing cards, what is the probability that all five are of the same suit?

Answers

Answer:

How many five-card hands dealt from a standard deck of 52 playing cards are all of the same suit? If a random hand is dealt, what is the probability that it will have this property?

Would the probability be:

(135)∗(41)(525)

Answer:

0.1965%

Explanation:

Because 13/52 are the same suit, we find the probability of 5 cards of the same suit (without replacemennt).

13/52=0.25

12/51=0.235

11/50=0.22

10/49=0.204

9/48=0.188

*multiply sums*

=0.0004957

*multiply by 4 since there are 4 different suits*

=0.001965x100=~0.1965%

Find the expressions that have a quotient of 7 R12. Drag the expressions to the box.
362 ÷ 50 492 ÷ 50 420 ÷ 60 408 ÷ 60 432 ÷ 60 502 ÷ 70 Quotient: 7 R12

Answers

The components of an integer division are dividend, divisor, quotient and a remainder.

The expressions with quotient 7R12 are: 362 ÷ 50 and 432 ÷ 60

Start by testing the options

[tex]\mathbf{362 \div 50}[/tex]

50 can divide 362 in 7 places and a remainder of 12.

So:

[tex]\mathbf{362 \div 50 = 7\ R\ 12}[/tex]

[tex]\mathbf{492 \div 50}[/tex]

50 can divide 492 in 9 places and a remainder of 42.

So:

[tex]\mathbf{492 \div 50 = 9\ R\ 42}[/tex]

[tex]\mathbf{420 \div 60}[/tex]

60 can divide 420 in 7 places and without a remainder

So:

[tex]\mathbf{420 \div 60 = 7}[/tex]

[tex]\mathbf{408 \div 60}[/tex]

60 can divide 408 in 6 places and with a remainder of 48

So:

[tex]\mathbf{408 \div 60 = 6\ R\ 48}[/tex]

[tex]\mathbf{502 \div 70}[/tex]

70 can divide 502 in 7 places and a remainder of 12.

So:

[tex]\mathbf{502 \div 70 = 7\ R\ 12}[/tex]

Hence, the expressions with quotient 7R12 are: 362 ÷ 50 and 432 ÷ 60
