The Johnson family income is
estimated to be $125,000 per year. Mary wanted to write this number
in scientific notation. If she wrote
1.25 x 10" , what value of n should
she use?
Answer:
The value of n would be 5
Step-by-step explanation:
This is understanding how to take numbers and writing them in scientific notation.
125,000 = 1.25 x 10⁵
First of all.
125,000 = 125,000.0 (See that decimal point?)
We want that decimal point behind the number 1 as seen in the scientific notation. All you have to do is move that decimal point to the left until you reach the ones place.
125000. → 1.25
(You're not finished yet)
Since we moved the decimal five times, then we must put an exponential value of 5 above the 10
In conclusion:
125,000 = 1.25 x 10⁵

Answer:
16
Step-by-step explanation:
q/4 + 14 = 18
q/4 + 14 - 14 = 18 - 14
q/4 = 4
q/4 x 4 = 4 x 4
q = 16
Answer:
q = 16
Step-by-step explanation:
Subtract 14 from each side, so it now looks like this: [tex]\frac{q}{4} = 4[/tex] Multiply each side by 4 to cancel out the 4 under q. It should now look like this: q = 16I hope this helps!

Answer:
Rate of change for the second one (at the top) is 10
x- intercept is (-10,0)
y- intercept is (0,20)
Step-by-step explanation:
Answer:
in bold below
Step-by-step explanation:
Left Side
If we let the price be represented by p and the quantity by q, then a suitable equation is ...
p/30 +q/35 = 1 . . . . equation in intercept form
7p +6q = 210 . . . . . multiply by 210
p = -6/7q +30 . . . . solve for p
The slope is -6/7.
The "rate of change" is -6/7. (slope and "rate of change" mean the same)
The x-intercept is 35.
The number at the end is zero (35). (assuming "the end" is the right end of the graph)
The starting price is the y-intercept (30).
The rate of cost is the slope (-6/7).
__
Right Side
The cost starts at 20 and goes up 10 for each 5 games, so 2 per game. A suitable equation is ...
y = 2x + 20
The rate of change is 2.
The x-intercept is where y=0. It will be -20/2 = -10.
The y-intercept is 20.
_____
The graph has to do with games and cost, not minutes and feet. There is insufficient information to answer questions about minutes and feet.
_____
Comment on these questions
The notations "per billions" on the left graph cause it to make no sense whatever. The ideas of "starting" and "ending" are usually time- or sequence-related. The graph shows nothing to indicate time or sequence. The idea of "rate of cost" for TV's is nonsensical. (Cost is a rate: dollars per unit.)
The first aircraft has 89 more seats than the second aircraft. The third aircraft has 45 fewer seats than the second aircraft. If their total number of seats is 401, find the number of seats for each aircraft
Answer: The first aircraft has 208 seats.
The second aircraft has 119 and the third has 74.
Step-by-step explanation:
The equation is x+89 + x + x-45 = 401
combine terms: 3x + 44 = 401 Subtract 44 from both sides 3x=357
divide both sides by 3
x= 119
substitute x in each term of the equation to find the number of seats on each aircraft
119 + 89 = 208 for #1 x= 119 for #2 119- 45= 74 for #3

A company sells herb blends for cooking. The tables below show the number of teaspoons for each herb in each blend and the cost for each blend.
What is the cost of basil per teaspoon?
o $0.15
o $0.18
o $0.19
o $0.23
Answer:
$0.23 or D
Step-by-step explanation:
Edg :)
The cost of one teaspoon of basil is $0.23. Therefore, option D is the correct answer.
We need to find the cost of basil per teaspoon.
How to interpret the data table?Interpretation of the data table is as follows:
Identify the subject under study.Identify the variable(s) presented in the table.Identify the measuring unit used (frequencies, percentages, rates, etc.)Read the information presented in table cells.Let the cost of one teaspoon of basil be $x, oregano be $y and parsley be $z.
Now, x+2y+3z=1.06-----(1), x+y+2z=0.72-----(2) and 2x+2y+z=0.99-----(3)
Equation (1)-(2), we get
x+2y+3z-(x+y+2z)=1.06-0.72
⇒y+z=0.34-----(4)
⇒z=0.34-y
Substitute z=0.34-y in equation (3).
That is, 2x+2y+0.34-y=0.99
⇒2x+y+0.34=0.99
⇒2x+y=0.65---(5)
Substitute z=0.34-y in equation (2)
Equation (5)-(4), we get
x+y+2(0.34-y)=0.72
⇒x+y+0.68-2y=0.72
⇒x-y=0.04-----(6)
Add equations (5) and (6), and we get
2x+y+x-y=0.65+0.04
⇒3x=0.69
⇒x=0.23
Therefore, the cost of basil per teaspoon is $0.23.

i’ve never really understood range
Answer:
( -∞, 3]
Step-by-step explanation:
Range is all possible y values that the graph covers.
So in this graph the legs extend all the way to y value -∞ (never mind the x value). However, the top is at y=3 and the graph is not extending above that. Hence the range is from -∞ to and including 3.
