On the way home from visiting his family, Vincent's plane cruised at an altitude of 3.2 x 104 feet. He had heard that a man named Felix
Baumgartner skydived from an altitude of 1.28 x 10$ feet. Vincent wants to know how much higher Felix went on his skydiving trip.
write the cruising altitude of vincent’s plane in standard notation
Answer:
Vincent’s plane is cruising at an altitude of 3.2 × 10^4 feet.
Convert the number to standard notation.
3.2 × 10^4 feet
=
3.2 • 10,000 feet
=
32,000 feet
Step-by-step explanation:
This is the sample answer from Edmentum.
Answer:
Question 1 part a =
Vincent’s plane is cruising at an altitude of 3.2 × 104 feet.
Convert the number to standard notation.
3.2 × 104 feet
= 3.2 • 10,000 feet
= 32,000 feet
Part b =
Felix’s skydiving altitude is 1.28 × 105 feet.
Convert the number to standard notation.
1.28 × 105 feet
= 1.28 • 100,000
= 128,000 feet
Part c =
Subtract the two altitudes to find the difference.
128,000 feet − 32,000 feet = 96,000 feet
The difference of their altitudes is 96,000 feet.
Part d =
The difference of the altitudes is 96,000 feet.
Covert 96,000 to scientific notation:
96,000 feet = 9.6 × 104 feet
Question 2 part a =
Vincent’s plane’s altitude is 3.2 x 10^4 feet.
Felix’s skydiving altitude is 1.28 x 10^5 feet.
Transform 3.2 x 10^4 so its exponent matches the power of 10 in 1.28 x 10^5.
To do so, multiply and divide the number by 10.
3.2 x 10^4 = 10/10 x 3.2 x 10^4
= 3.2/10 x 10^4 x 10
= 0.32 x 10^5
Part b =
Calculate the difference of the two altitudes:
1.28 × 105 – 0.32 × 105
= (1.28 – 0.32) • 105
= 0.96 • 105
The difference of their altitudes is 0.96 •105 feet.
Part c =
The difference of Vincent’s and Felix’s altitudes is 0.96 x 10^5 feet.
To convert the answer to scientific notation, multiply and divide the number by 10.
0.96 x 10^5 = 10/10 x 0.96 x 10^5
= (0.96 x 10) x (10^5 x 10^-1)
= 9.6 x 10^4 feet
In scientific notation, the difference of Vincent’s and Felix’s altitudes is 9.6 x 10^4 feet.
Question 3 =
The altitudes are the same. That means you can subtract numbers given in scientific notation using either of two methods: convert them to standard notation and then perform the subtraction, or subtract the numbers in scientific notation without converting them to standard notation.

8. David is having a Super Bowl party and he needs
bottled water. Which of the following purchases will give
him the lowest unit cost?
a) $1.80 for a 6 pack
b) $6.00 for a 24 pack
c) $4.80 for a 12 pack
d) $10.00 for a 36 pack
Answer:
D) 10.00 for a 36 pack
Step-by-step explanation:
(I'm going up by the smallest pack to the highest because I noticed they are all multiples of 6)
1.80 for a 6 pack (double it to become a 12 pack)
3.60 for a 12 pack but the other 12 pack is more expensive making a 6 pack cheaper. (add another 6 pack)
5.40 for a 18 pack (add another 6pack)
7.20 for a 24 pack so this means the 6pack is more expensive and a 24pack is cheaper (in gonna keep adding till we get to 36 pack)
9 for a 30 pack
10.80 for a 36 pack

Answer:
x = 3
y = 2
Step-by-step explanation:
5x + 4y= 23
x - y = 1 then x = y + 1
substitute for x:
5(y + 1) + 4y = 23
simplify:
9y = 18
y = 2
x = 2 + 1 = 3
check:
3-2 = 1
1 = 1
and:
5(3) + 4(2) = 23
23 = 23

Simplify 1000^2/3 and find the index.
Answer:
100
Step-by-step explanation:
Here, we want to simplify the given indices and also get the index
The index is simply the power or exponent 2/3 and that is the index
1000^2/3
we can use the law of indices here;
1000^2/3 =( 3√(1000)^)2
the cube root of 1000 is 10
so we have 10^2 = 100
Write the sum using summation notation, assuming the suggested pattern continues. -3+6+15+24+...+132
Answer:
Option (4)
Step-by-step explanation:
Given sequence is,
-3 + 6 + 15 + 24 + ........+ 132
Difference in 1st and 2nd term = 6 - (-3)
= 9
Difference in 2nd and 3rd term = 15 - 6
= 9
There is a common difference of 9 in each successive term.
Therefore, it's an arithmetic sequence.
Let the nth term of this sequence is (a + bn).
For the first term → n = 0,
a = -3
For second term → n = 1
-3 + b(1) = 6
b = 6 + 3
b = 9
Therefore, nth term of the sequence will be,
[tex]T_n[/tex] = -3 + 9n
For nth term = 132
-3 + 9n = 132
9n = 135
n = [tex]\frac{135}{9}[/tex]
n = 15
Sum of 15 terms can be represented by the expression;
[tex]\sum_{n=0}^{15}(-3+9n)[/tex]
Option (4) is the answer.

Shannon rolled a number cube 50 times. A "4" appeared 15 times. Find the ratio of the number of times four appeared to the total number of rolls.
Answer:
3 : 10
Step-by-step explanation:
Given that :
Total number of rolls = 50
Nunber of times '4' appeared = 15
Expressing the Number of times 4 appeared and the total number of rolls as a ratio:
Number of times 4 appear : total number of rolls
15 : 50
We reduce the the lowest term :
Divide both sides by 5
3 : 10

There are 101 Year 13 pupils in a tennis club, out of a total of 146 pupils. Write this proportion as a percentage. Give your answer correct to 1 decimal place when appropriate.
Answer: 69.2%
Step-by-step explanation:
There are 101 Year 13 students out of a total number of 146 pupils.
To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:
= Year 13 students/ Total students * 100%
= 101 / 146 * 100%
= 0.692 * 100%
= 69.2%

Re-write the quadratic function below in standard form y=3(x+4)(x+1)
Answer:
y = 3x² + 15x + 12
Step-by-step explanation:
A quadratic function in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = 3(x + 4)(x + 1) ← expand the factors using FOIL
= 3(x² + 5x + 4) ← distribute parenthesis by 3
= 3x² + 15x + 12
Plan help with one I really need it
Answer:
Step-by-step explanation:
1) Area of garden = side * side
= 10* 10
= 100 Sq.m
2) Area of each flowerbed = 1*1 = 1 sqm
3) Area of 4 flowerbed = 1 * 4 = 4 sqm
Area of the remaining garden = Area of garden - area of 4 flower bed
= 100 - 4
= 96 sq.m
4) Length of the fence = 4 *side
= 4 * 10 = 40 m
5) Cost of planting in the remaining garden = 96 * 20
= ₹ 1920
