brainliest. follow anything . box of chocolates contains seven milk chocolates and six dark chocolates. Five of the milk chocolates and four of the dark chocolates have peanuts inside. You randomly select a chocolate and eat it. What is the probability it is a dark chocolate with peanuts?
options=2/3, 4/13, 11/13 and 8/13
Answer: 4/13
Step-by-step explanation: There are a total of 13 chocolates, and 4 of those are dark chocolate with peanuts.
Probability that the chocolate you eat is a dark chocolate with peanuts is 4/13.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Total number of milk chocolates = 7
Total number of dark chocolates = 6
Number of milk chocolates that have peanuts inside = 5
Number of dark chocolates that have peanuts inside = 4
Total number of chocolates = 7 + 6 = 13
Probability that the randomly selected chocolate is a dark chocolate with peanuts = 4/13
Hence the required probability is 4/13.

The shadow of the tree is 40 feet long. A yard-stick placed next to the tree casts a 6 foot shadow. How tall is the tree?
Answer:
pretty sure the tree's 20 feet
According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
We know 1 yard is 3 feet.
Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.
∴ x : 40 : : 3 : 6.
x/40 = 3/6.

Lexi say that -68 feet is a greater depth than- 75 feet, since-68>-75. Is Lexi correct? Explain
Answer:
No
Step-by-step explanation:
When working with negative numbers in terms of depth, greater depth are depicted by values as we move farther to the left of the number line.
With this in mind, - 75 feets is farther to the left of the number line and as such represents a greater depth value Than - 68 feets
Therefore, when expressing depth or elevation distances, the values should be iewwd in absolute terms. Then |75| > |68|. While bearing in mind that depth is downward and thus negative
Solve for the value of the variable: 7x+ 10 = 4x + 16
Enter the answer
Step-by-step explanation:
7x + 10 = 4x + 16

3x = 6 (subtract 10 on both sides)
x = 2 (divide 3 on both sides)

Jeffrey went to the Outlets to buy some clothes. He bought a pair of pants for $59.99 and a nice shirt for $32.00. He read a sign saying that he would receive 30% off for all purchases. How much did Jeffrey spend?
Answer: 64.39 dollars
==========================================================
Explanation:
Before the discount, he would spend 59.99+32 = 91.99 dollars. This is before sales tax is added.
However, he gets 30% off, so he saves 0.30*91.99 = 27.597 = 27.60 dollars.
Meaning that he actually spends 91.99 - 27.60 = 64.39 dollars
--------------
As a shortcut, we can multiply 91.99 by 0.70 to get 64.393 which rounds to 64.39
The 0.70 is due to the fact that if he saves 30%, then he still has to pay the remaining 70%
Keep in mind that sales tax would need to be added on; however, your teacher doesn't mention the sales tax rate.

Answer:
x = 70
Step-by-step explanation:
180* (n-2)
180*(6-2)
180*(4) = 720
102 + 146 + 120 + 124 + 158 = 650
720 - 650 = 70
A polygon is a planar figure characterized by a limited number of straight-line segments. The value of the x is 70°.
What is a polygon?A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of the interior angles of a n-sided polygon is calculated using the formula,
Sum of the interior angles = (n-2) × 180°
For the given polygon, the number of sides is equal to 6. Therefore, the sum of the interior angles of the polygon is,
Sum of the interior angles = (6-2) × 180°
= 4 × 180°
= 720°
Further, the sum of the interior angles for the given polygon can be written as,
Sum of the interior angles = 102° + 146° + 120° + 124° + 158° + x°
720° = 102° + 146° + 120° + 124° + 158° + x°
x = 720° - (102° + 146° + 120° + 124° + 158°)
x = 720° - 650°
x = 70°
Hence, the value of the x is 70°.

Maria and Veronica were asked to add two whole numbers. Instead, Maria subtracted the two numbers and got 10 while Veronica multiplied them and got 651. What was the correct sum
Answer:
31 + 21 = 52
Step-by-step explanation:
Calculation for the correct sum
First step is to factor 651 which means that 1 * 3 * 7 * 31 will give us 651
Second step is to find 3 possibilities numbers that will give us 10 as the difference
3 possibilities numbers =(31, 21), (93, 7), (217, 3)
Third step is to make use of equation 1 to find the numbers that has 10 as the difference among the 3 possibilities numbers
The number that has 10 as the difference is (31, 21) because 31-21 will gives us 10
Now Equation 1 = X – Y = 10
Where,
X=31
Y=21
Hence,
31 – 21 = 10
Since 31 – 21 gave us 10 as the difference which means that the correct sum will be:
Correct sum =31 + 21 = 52
Therefore the Correct sum is 31 + 21 = 52
Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

The population of a town was 25000 in the 2000 census and and 30000 in 2010 census. By what percent did the population increase
Answer: This means that the population increased a 20% between the year 2000 and the year 2010.
Step-by-step explanation:
In this case, we have that 25,000 is the 100%.
Now we want to know which percentage represents 30,000
Let's suppose that the percentage is X.
Then we can have a system of equations:
30,000 = X
25,000 = 100%
To find the value of X, we can take the quotient of these two equations:
30,000/25,000 = X/100%
(30,00/25,000)*100% = X = 120%
Then in the 2000 we had a 100%, and in the 2010 there was a 120%.
The difference is:
120% - 100% = 20%
This means that the population increased a 20% between the year 2000 and the year 2010.
