Question
Scientific notation is commonly used in science, technology, engineering, and math, which are known as
STEM fields. Assume there are approximately 2.6 million engineers in a country. If engineers make an
average salary of about $70,000 per year, how much income does this group generate collectively?
Write the answer in both scientific and standard notation.
Answer:
$182000000000
1.82 * 10^11
Step-by-step explanation:
Given that :
Number of engineers = 2.6 million
Average salary = $70,000
Collective income generated by group of engineers yearly :
This will be on average :
2,600,000 * 70,000 = $182000000000
In scientific notation :
$182000000000 = 182 * 1000000000
182 * 1000000000 = 182 * 10^9
182 = 1.82 * 100 = 1. 82 * 10^2
Hence,
$182000000000 = 1.82 * (10^2 * 10^9)
$182000000000 = 1.82 * 10^11
The diameter of a foot ball is 12cm ?find itsvolume
Answer:
288 [tex]\pi[/tex] cm³
Step-by-step explanation:
diameter = 12 cm
radius = diameter/ 2
= 12/ 2
= 6 cm
volume of a sphere = 4/ 3 × [tex]\pi[/tex] × (6)³
= 4/ 3 × [tex]\pi[/tex] × 216
= ( 864 [tex]\pi[/tex])/ 3
= 288 [tex]\pi[/tex] cm³

Find segment ET. Please and thank you
Answer:
x=9
Step-by-step explanation:
Use the intersecting chord theorem:
RE*ET = UE*ES
Substitute values
21 (2x+2) = 30 (x+5)
Expand:
42x+42 = 30x + 150
transpose and simplify
42x-30x = 150 - 42
12x = 108
x = 9
If someone vapes for every 15 minutes in a total of 16 hours how many times would they vape in those 16 hours
Answer:
64 times
Step-by-step explanation:
There are 4 sessions of 15 minutes in an hour. Meaning that a person would vape 4 times in an hour. 4 * 16 = 64. A person vapes 64 times in 16 hours. o-o dont vape kids.
Answer and Step-by-step explanation:
We are given the ratio of 1 vape every 15 minutes. We need to convert the time to hours, then multiply the hours by 16.
1 : 15
We know that there are 60 minutes in 1 hour, so we need to multiply 15 by 4 to get 60.
15 × 4 = 60
We also need to multiply 1 by 4, so that the result will be a multiple of the beginning number and so that we didn't get random numbers from somewhere.
1 × 4 = 4
Now we have the ratio 4 : 60, which means that the person vapes 4 times every 60 minutes, or every hour. But since we turned the minutes into an hour, this turns the 60 into a 1. 4 : 1
Now, we have to multiply 4 and 1 by 16 to get the amount of vapes done in 16 hours.
4 × 16 = 64
1 × 16 = 16
So, we have the ratio 64 : 16
This means that the person smokes 64 times in the 16 hours.

A rope has a density and thickness such that a 3.25-centimeter-long segment of it weighs 61.40 grams. There are 28.3495 grams in an ounce and 2.54 centimeters in an inch. How many ounces would a 19.45 inch length of the same rope weigh
Answer: [tex]32.909\ \text{ounce}[/tex]
Step-by-step explanation:
Given
3.25 cm long segment of rope weighs [tex]61.40\ gm[/tex]
Using unitary method
1 cm of a segment measures
[tex]\dfrac{61.40}{3.25}=18.892\ gm[/tex]
[tex]1\ cm\equiv 18.892\ gm[/tex]
converting cm to inch and gm to ounce
[tex]\dfrac{1}{2.54}\ in.\equiv \dfrac{18.892}{28.3495}\ \text{ounce}\\\\1\ in.\equiv \dfrac{18.892}{28.3495}\times 2.54\ \text{ounce}\\\\1\ in.\equiv 1.692\ \text{ounce}[/tex]
for 19.45 in., weight is
[tex]\Rightarrow 19.45\ in.\equiv 1.692\times 19.45\\\\\Rightarrow 19.45\ in\equiv 32.909\ \text{ounce}[/tex]

Find (-5) when f(x) = x^2 + 2x + 5
Answer:
Value of F(x) when x = -5 is 20
Step-by-step explanation:
Given equation;
f(x) = x² + 2x + 5
f(x) = f(-5)
Find:
Value of F(x) when x = -5
Computation:
Given function;
f(x) = x² + 2x + 5
By putting value of x in given function
f(-5) = (-5)² + 2(-5) + 5
f(-5) = (-5 x -5) + 2(-5) + 5
f(-5) = (25) - 10 + 5
f(-5) = (25) - 5
f(-5) = 20
Value of F(x) when x = -5 is 20
Mark packed 1-inch cubes into a box with a volume of 96 cubic inches. How many layers of 1-inch cubes would it take to fill the box?
Answer:
4 approx.
Step-by-step explanation:
The number of layers of 1-inch cubes that Mark packed is determined by assuming that the larger box is also a cube.
let the N be the number of layers of 1-inch cubes that would it take to fill the box.
Since the larger box is also a cube
Therefore, 96 = N^3
N = (96)^(1/3)
N = 4√6
Therefore, there would be 4 layers of the 1-inch cube and some extra incomplete layer

Answer:
<FGH and <JKL are supplementary
<AED and <BEC are complementary
Step-by-step explanation:
For supplementary angles, the sum of the pair of angles must be 180degrees
Given;
<FGH = 109degrees
<JKL = 71degrees
Taking the sum
<FGH + <JKL
= 109 + 71
= 180
Since the sum of the angles is 180, hence <FGH and <JKL are supplementary
Similarly;
Given
<AED = 45degrees
<BEC = 45degrees
Taking the sum
<AED + <BEC
= 45 + 45
=90degrees
Since the sum of complementary angles is 90degrees, hence <AED and <BEC are complementary

The softball in the mitt is 4.9 inches in diameter. What is its volume? (Use 3.14 for )
Volume is a three-dimensional scalar quantity. The volume of the softball is 61.6 cubic inches.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given that the diameter of the softball is 4.9 inches. Since the radius is half the diameter, therefore, the radius of the softball can be written as,
Radius = Diameter
= 4.9 inches / 2
= 2.45 inches
Now, the volume of the softball can be written as,
Volume of the softball = (4/3) × π × r³
= (4/3) × π × (2.45 inches)³
= 61.6 inches³
Hence, the volume of the softball is 61.6 cubic inches.
