There are two solid hemispherical objects made of clay having the same shape and size. If the total surface area of one hemispherical object is 462 square cm, find the total surface area of the sphere which is formed by attaching those two hemispherical objects.
The area of a 2D form is the amount of space within its perimeter. The total surface area of the formed figure is 615.75216 cm².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given that the total surface area of one hemispherical object is 462 square centimeters, therefore, we can write,
The total surface area of the hemisphere = 3πr²
462 cm² = 3πr²
r² = 462/(3π) cm²
r² = 49.0197 cm²
r = 7 cm
Now, when the two hemispheres will be attached, the total surface area of the formed figure will be equal to the total surface area of a sphere,
Therefore, we can write,
Total surface area = 4πr²
= 4 × π × (7 cm)²
= 615.75216 cm²
Hence, the total surface area of the formed figure is 615.75216 cm².

Why is it difficult to identify the slope of the line `6x-2y=12`?
Answer:
Prolly cause it's not in slope intercept form.
Step-by-step explanation:
To make the equation into slope-intercept form, first subtract 6x from both sides.
-2y = -6x + 12
Divide everything by -2.
y = 3x - 6
There is your slope-intercept equation. -6 is the y-intercept and 3 is the positive slope.

The Hu family goes out for lunch, and the price of the meal is $54. The sales tax on the meal is 6%, and the family also leaves a 15% tip on the pre-tax amount. What is the total cost of the meal?
Answer:
The total cost of meal is $65.34
Step-by-step explanation:
Price of the meal = $54
Sales tax on meal = 6%
Tip given= 15% on pre-tax amount
We need to find total cost of meal.
First finding sales tax amount:
We need to calculate 6% of 54
[tex]6\% \ of \ 54\\=6\% \times 54\\=\frac{6}{100}\times54\\=3.24[/tex]
So, the sales tax would be $3.24
Now, we need to find tip amount
We will find 15% of 54
[tex]15\% \ of \ 54\\=15\% \times 54\\=\frac{15}{100}\times54\\=8.1[/tex]
So, the tip given would be $8.1
The total cost of meal = Price of meal + Sales Tax + Tip
= 54+3.24+8.1
= 65.34
So, the total cost of meal is $65.34

Elevator 1 moved up 10 feet from the ground level. its position is labeled as +10. Elevator 2 moved down 5 feet from the ground level. It’s position is labeled as _____
Answer:
I believe your answer would be -5 because in the first part of the question, it tells you that ground level is 0. (by saying that when you go up 10 from ground level, you are at postitive (+)10)
so... if you go 5 down from ground level (0), it the same as 0-5 which is -5. hope this helps! :)

Each dimension of a parallelogram is multiplied by a positive number n. Write an expression for the area of the new parallelogram. Let b represent the base and h represent the height of the original parallelogram. Expression for the area of the new parallelogram:
Answer:
Area of the new parallelogram = n(b × h)
Step-by-step explanation:
Area of a parallelogram = Base × Height
Let
b = the base
h = the height of the original parallelogram.
Each dimension of a parallelogram is multiplied by a positive number n.
Write an expression for the area of the new parallelogram.
Area of the new parallelogram = Base × Height
Base = b * n
bn
Height = h * n
= hn
Area of the new parallelogram = bn × hn
= n(b × h)
Area of the new parallelogram = n(b × h)

Kelly divided of 5/7 a liter of plant fertilizer evenly among some smaller bottles. She put 1/5 of a liter into each bottle. How many smaller bottles did Kelly fill? Pls help
Answer:
3 bottles
Step-by-step explanation:
Given that :
Total liters of fertilizer = 5/7 litres
Amount put into each smaller bottle = 1/5 liters
Number of small bottles filled :
Total liters of fertilizer ÷ amount put into smaller bottles
5/7 litres ÷ 1/5 litres
5 /7 * 5 /1
= 25 / 7
= 3.57
Hence, 3 bootles was filled

A hockey puck has a diameter of 7.6 cm and a height of 3.4 cm. What is the volume of a cylindrical package containing six pucks? Express your answer to the nearest cubic centimeter.
Answer:
[tex]924.96\ cm^3[/tex]
Step-by-step explanation:
Given that,
The diameter of a hockey puck, d = 7.6 cm
Height, h = 3.4 cm
We need to find the volume of the volume of a cylindrical package containing six pucks.
Volume of 1 puck,
[tex]V=\pi r^2 h\\\\=3.14\times (3.8)^2\times 3.4\\\\=154.16\ cm^3[/tex]
Volume of 6 pucks,
[tex]V=6\times 154.16\ cm^3\\\\=924.96\ cm^3[/tex]
So, the volume of the 6 puck is [tex]924.96\ cm^3[/tex].
Given the dimensions of a single hockey puck, we want to find the volume of a cylindrical package containing six pucks. We will see that the volume must be 925 cm^3
So the volume of a cylinder of diameter D and height H is:
V = 3.14*(D/2)^2*H
Here we have:
D = 7.6cmH = 3.4cm.Then the volume of each single puck is:
V = 3.14*(7.6cm/2)^2*3.4cm = 154.16cm^3
Then the volume of a package that contains 6 of these must have at least 6 times that volume:
6*V = 6*154.16cm^2 = 924.96 cm^3
Rounding to the next cubic centimeter we get 925 cm^3
So the volume of the package must be 925 cm^3

72(x+2) = 108x

Step-by-step explanation:
If you know two points on a line, you can use them to write the equation of the line in slope-intercept form. The first step will be to use the points to find the slope of the line. This will give you the value of m that you can plug into y = mx + b. The second step will be to find the y-intercept.

Mr. Randall, a salesperson, earns a weekly salary of $300 plus a commission of 7% of his weekly sales of merchandise. Last week, Mr. Randall earned $426. This can be represented by the equation below, where s represents his total sales, in dollars, for the week.
Answer:
Step-by-step explanation:
Step one:
given data
we are told that weekly salary is $300
and a commission of 7% of the weekly sales
let the sales be s
7% of s = 0.07s
hence weekly commission = 0.07s
let the total earning be y
the linear model for Mr. Randall earnings is
y=300+0.07s
step two:
For the situation whereby he earned $426
the model is given as
426=300+0.07s
let us solve for s, the sales made
426-300=0.07s
126=0.07s
divide both sides by 0.07
s=126/0.07
s=1800
Hence he made sales of $1800 for that week
