Answer:
x = 54°
Step-by-step explanation:
(5-2)·180° = 540°, which is the total amount of degrees inside a pentagon
if it's regular then each angle is equal so m∡B = 540/5 or 108°
∠DBC ≅ ∠CDB because ΔCBD is isosceles
half of 108 is 54°

60 square feet. Use the formula for the surface area of a sphere:
S=471?
to find the radius of the pinata in feet.
Answers
Answer:
2.19 ft
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
Surface area of the sphere = 60 ft²
The formula to find the radius of a sphere
= √A/4π
= √60/4 × π
= 2.19 ft
Therefore, the radius of the pinata = 2.19 ft
What is the value of x?
Answers
Answer:
x = 80 degrees
Step-by-step explanation:
First look at the upper triangle. There are two 65 degree angles there, along with two equal sides. The angles must sum up to 180 degrees. Therefore:
2(65) + x = 180; thus, the value of x is 50 degrees.
Next, recognize that the vertical angles in the middle of the diagram are equal and are 50 degrees each. Thus, the smaller triangle has two 50-degree angles. Again we sum up the angles, obtaining 50 + 50 + x = 180, or x = 80 degrees

Answers
The equivalent of the complex number expression is [tex]\sqrt{60i - 11}[/tex] is 2 + 15i
How to rewrite the expression?The complex number expression is given as:
[tex]\sqrt{60i - 11}[/tex]
Rewrite as:
[tex]a + bi = \sqrt{60i - 11}[/tex]
Take the square of both sides
[tex]a^2 + 2abi - b = 60i - 11[/tex]
By comparison, we have:
a^2 - b = -11
2ab = 60
Divide both sides by 2
ab = 30
Using a graphical tool, we have:
a = 2,b = 15
So, we have:
a + bi = 2 + 15i

Answers
Answer:
101.33333 minutes
Step-by-step explanation:
Given :
Leakage rate = 3 ounces per 19 minutes
Time it'll take for 16 ounces of juice in the container to leak out
The leakage rate on ounce per minute :
3 ounces / 19 minutes = 0.1578947 ounce per min
1f 0.1578947 ounces leak out in 1 minutes
16 ounces will leak out in x minutes
Hence ;
0.1578947x = 16 ounces
x = 16 / 0.1578947
x = 101.33335 minutes
OR :
3 ounces = 19 minutes
1 ounce = (19 / 3) = 6.333333 minutes
16 ounces = (15 + 1) ounce
15 ounces = 3 * 5
Hence, 15 ounces will leak in (19 minutes * 5) = 95 minutes
1 ounce = 6.33333 minutes
Hence,
16 ounces will leak in (95 minutes + 6.33333 ounces) = 101.33333 minutes
HENCE, All 16 ounces will leak out in 101.33333 minutes

Answers
Answer:
324/540 cats and dogs should be expected to be given away
Step-by-step explanation:
First, write the fraction of the cats on the spinner plus the dogs on the spinner.
[tex]\frac{4}{10} + \frac{2}{10} = \frac{6}{10}[/tex]
Now, we have to make the denominator 540 but we have to make it equal so you divide.
540 ÷ 10 = 54
So, our fraction should look like this.
[tex]\frac{x}{540}[/tex]
Now, multiply 6 × 54 = 324
[tex]\frac{324}{540}[/tex] is our answer
Have a great day!
The dog or cat toys are expected to be given away = 378
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
If the spinner is spun 540 times throughout the day.
Total fraction of the cat and dogs together,
= 5/10+2/10
=7/10
Divide the 540 into 10 equal parts,
= 540/10
=54
let 'x' dog or cat toys are expected to be given away
So, x/540 = 7/10
x= 54*7
x= 378.
Hence, dog or cat toys are expected to be given away = 378/540
