Knowing the surface of an object would be useful for:
- the amount of paint needed to paint a room
- how much wrapping paper a gift will need
What is Surface Area?
Surface area is the total area covering the outside of a 3D shape.
By knowing this number, we can count the amount of paint needed to paint a room, how much wrapping paper a gift will need, etc.
On the paint pail, we can find the information about its coverage. for example: 1 liter of paint will cover 6 m2 of wall. When we know the area of wall, we can count the pail needed.Once we know the area of the wrapping paper area and the gift’s surface, we can count the wrapping paper needed.On the other side, when we talk about the amount of water needed to fill an aquarium, how many watermelons fit in a box for shipping, the amount of gasoline left in the tank of vehicle, etc. we have to know the volume of the related variables.

Find the area of the circle. Round your answer to two decimal places, if necessary.
Answers
200.96 cm
Step-by-step explanation:Area of a circle: [tex]A=[/tex] [tex]\pi r^2[/tex]Since we don't have the radius, we have to find it.
What you gave me is the diameter which is 16 (cm) I suppose.
Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.
[tex]16[/tex] ÷ [tex]2=8[/tex]
This is our radius.
Plug this into the area formula.
[tex]A=\pi r^2[/tex]
[tex]A=(3.14)(8)^2[/tex]
[tex]A=200.96cm[/tex]

Answers
Answer:
3 outfits with $3.92 as change
Step-by-step explanation:
The inequality represents the maximum number of outfits Alexa can purchase while staying within her budget is 520 ≥ 47.20o + 372.92.
What is inequality?A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
As per the given,
Bicycle cost = $342.82
4 bicycle reflectors cost = 4 × 3.90 = $15.6
Gloves cost = $14.51
Cost of "o" biking outfit = 47.72o.
Total cost ≤ Budget.
342.82 + 15.6 + 14.51 + 47.72o ≤ 520
372.92 + 47.20 o ≤ 520
520 ≥ 47.20o + 372.92
Hence "The inequality represents the maximum number of outfits Alexa can purchase while staying within her budget is 520 ≥ 47.20o + 372.92".

Esteban has `3` kittens. According to the vet, each kitten is born with blue eyes and there is a `50\%` chance of it changing color once they reach three months. Esteban decides to run a simulation using `3` coins, where heads represent the eyes changing color.
The table shows the results of his simulation.
Estimate the probability that at least one of Esteban’s kittens will still have blue eyes at three months old.
Answers
Answer:
89%
Step-by-step explanation:
Since Esteban ran a simulation with 100 different tries, we add up all the tries that say at least one kitten will have blue eyes. This equals 89, so the answer is 89%.

A farmer ships apples in crates that weigh 4.5 lb each when empty. Each apple weighs 0.37 lb. The total weight of a crate filled with apples is 60 lb. Write a word equation you could use to find the number of apples packed in each crate.
choses are in the image
Answers
Answer:
E. total weight = weight of crate + (weight of one apple) × (number of apples)
Step-by-step explanation:
Total weight = 60 lb
Weight of crate = 4.5 lb
Weight of one apple = 0.37 lb
Let's assume, the weight of apples in the crate is "x".
x = Total weight - weight of crate ----- 1
Let's assume, the number of apples in a crate is "y".
y = x ÷ (weight of one apple) ------------ 2
[make x the subject of equation 2]
x = y × (weight of one apple) ------------ 3
[put equation 3 into equation 1]
y × (weight of one apple) = total weight - weight of crate
[make "total weight" the subject]
Total weight = y × (weight of one apple) + weight of crate.
[y is the number of apples)
Total weight = (number of apples) × (weight of one apple) + weight of crate

In the graph of an inequality, the area above a dashed line through the points (−6, 4) and (2, 4) is shaded. Which inequality does this graph represent?
A. y ≥ 4
B. y ≤ 4
C. x > 4
D. y > 4
Answers
Answer:A. y ≥ 2
Step-by-step explanation:
First the line is solid, a complete line not dotted so the inequality sign to use is : ≥ or ≤
The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :
y ≥ 2
