The side of a cube measures \large 2.2\times10^{-6} cm. What is the volume of the cube in cubic centimeters? Write your answer in scientific notation.
Answers
Answer:
The volume is [tex]10.648 \times10^{-18}[/tex] cm³
The scientific notation [tex]1.0648 \times10^{-17}[/tex] cm³.
Step-by-step explanation:
Consider the provided information.
The side of a cube measures [tex]2.2\times10^{-6}[/tex] cm.
The volume of cube = [tex]s^3[/tex]
Where, s is the side.
The volume of cube: [tex]V=(2.2\times10^{-6})^3[/tex] .
[tex]V=(2.2)^3 \times(10^{-6})^3[/tex]
[tex]V=10.648 \times10^{-18}[/tex]
Hence, the volume is [tex]10.648 \times10^{-18}[/tex] cm³
The scientific notation [tex]1.0648 \times10^{-17}[/tex] cm³.

Find two positive numbers that satisfy the given requirements. The sum of the first number squared and the second number is 54 and the product is a maximum.
Answers
Answer:
36
Step-by-step explanation:
Calculation to Find two positive numbers
First step
Let the first positive number be a
Let the second positive number be b
Second step is to create the Equation
a^2+b= 54....... Equation (1)
b = 54-a^2........ Equation (2)
Third step is to find the product
Product= a(54-a)^2 = 54a-a^3
Fourth step is to differentiate
dP/dx = 54-3a^2
dP/dx = 0
Fifth step is to solve for 54-3a^2 = 0
Hence,
3a^2=54
a^2 = 18
Last step
a= √(18)
b= 54-(√(18))^2
b=54-18
b = 36
Therefore the two positive numbers are 36

Answers
Answer:
to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Kai needs to replace the strip laminate that is glued to the vertical faces on a square tabletop. The tabletop is 1.69 m2. What length i laminate does he need
Answers
Area of a square = Side x Side (length x width)
A = 1.69 m²
Length = √area of square
L = √1.69 m²
L = 1.3 m
Check Work: 1.3² = 1.3 m x 1.3m
= 1.69 m²
Answer:
he needs 1.3 meters of laminate for the length
Step-by-step explanation:
area of a square = side multiplied by side (or length x width)
area = 1.69 m²
Length = √area of square
L = √1.69 m² or 1.3m

After travelling for 3 hours at an average speed of 70 km / hour,
James was still 48 km from home. How far away from home was
James when he started his journey? __ km
Answers
Answer:
258 km
Step-by-step explanation:
To find how much he traveled:
(70 hm/hour) * ( 3 hours) = 210 km
so he traveled 210 km but still 48 km away from his home, then we need to add the values.
210 km + 48 km = 258 km

Answer:
a= 12, b= 24, c = 12, d= 12root3
Step-by-step explanation:
Because the triangle to the left is a right triangle with a 45 degree angle, we can deduce that it is a 45-45-90 special triangle where a =c. Furthermore, a and c = the hypotenuse divided by root 2.
12 root 2 / root 2 = 12
a=12, c=12
The triangle to the right is a right triangle with a 30 degree angle, so it is a 30-60-90 special right triangle.
If a = 12, b is 2 times a
b= 2*12 = 24
If a =12, d = a * root 3
d= 12root3

Five plus 6 times a number is equal to 21 minus 2 times the number
Your equation is this:
5+6x=21-2x
Subtract 6x from both sides
5+6x-6x=21-2x-6x
5=21-8x
subtract 21 on both sides
5-21=21-21-8x
-16=-8x Divide -8 on both sides
2=x
