Answer:
From Post Office to Store is 7.8 miles Henry would walk 2.2 hStep-by-step explanation:
From Post Office (P) to Library (L) is 6 miles, from Store (S) to Library (L) is 5 miles. And angle SLP is right angle (m∠SLP=90°).
So, from Pythagorean theorem:
[tex]SL^2+PL^2=SP^2\\\\5^2+6^2=SP^2\\\\SP^2=25+36=61\\\\SP=\sqrt{61}=7.810 249...\approx7.8[/tex]
If Henry walks 3.6 mph then:
[tex]3.5\qquad-\quad\quad1\,h \\7.8\qquad-\qquad x\\\\ x=\dfrac{7.8\cdot1\,h}{3.5}=\dfrac{78\,h}{35}=2,22857...\, h\approx2.2\,h[/tex]

A cash register contains q quarters. Write an algebraic expression that represents the total amount of money (in dollars).
Answers
Answer:
0.25q
Step-by-step explanation:
A cash register is a machine used in small business that sums, display and records the total amount made by each sale. A cash register also has a drawer which is used to store money.
A quarter is a coin in the United States which is 25 cents.
Converting 25 cents to dollars:
100 cents = $1
25 cents = 25 cents × $1 / 100 cent = $0.25
The total amount of money registered = number of quarters × $0.25
The total amount of money registered = q × $0.25 = 0.25q
Graph the line passing through (-6,-3) whose slope is m=2
Answers
Answer:
Start at (−6,−3) and count up 2 units and right 1 unit to find a second point. Connect the two points with a line to find the graph.
Step-by-step explanation:
Start by plotting the point (−6,−3). Use the slope formula m=rise/run to identify the rise and the run.
m=2
rise/run = 2/1
rise = 2
run = 1
Start at (−6,−3) and count up 2 units and right 1 unit to find a second point. Connect the two points with a line to find the graph.

Place the terms into the correct column that describes the reactions of photosynthesis.
Word bank:
Processes: ATP Synthase, Calvin Cycle, Electron Transport Chain, Photosystem I, Photosystem II
Locations: Stroma, Thylakoids membrane
Reactants: ADP, ATP, Carbon Dioxide, NADP+, NADPH, Sunlight, Water
Products: ADP, ATP, NADPH, NADP+, Oxygen, Sugars
Answers
Answer:
Please find the correct placement in a tabular format in the attached image. The explanation has been done below.
Step-by-step explanation:
The process of photosynthesis occurs in two stages viz: light-dependent and light-independent reactions.
- In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.

Question 3 options: If 2y+13=y+5 then 2y + 1 = 3y + ___. What number would go in the blank? If you continued to solve, would y = - 14? state either yes or no
Answers
Answer:
Step-by-step explanation:
Given the expression 2y+13=y+5
To get the value of y, we willow the following steps:
Subtract 2y to both sides:
2y+13-2y = y+5-2y
13 = -y+5
subtract 5 from both sides:
13-5 = -y+5-5
8 = -y
-y = 8
multiply both sides by -1
-(-y) = -8
y = -8
Hence the value of y = -8 not -14
So NO,if you continue to solve, y would not be -14

A local bank charges $9 per month plus 24 per check. The credit union charges $7 per month plus 4e per chock. How many checks should be written each month to make the credit union a bottor deal?
The credit union is a better deal when writing or fower checks per month
Answers
This question was not properly written
Correct Question
A local bank charges $9 per month plus 2c per check. The credit union charges $7 per month plus 4cper check. How many checks should be written each month to make the credit union a better deal?
The credit union is a better deal when writing fewer checks per month
Answer:
Writing between 0 to 99 checks makes the credit union a better deal.
Step-by-step explanation:
Let the number of checks be represented by x
Note, 1 cent = $0.01
A local bank charges $9 per month plus 2c per check.
2c = $0.02
$9 + 0.02× x
= 9 + 0.02x
The credit union charges $7 per month plus 4c per check.
4c = $0.04
= $7 + 0.04 × x
= 7 + 0.04x
The credit union is a better deal when writing fewer checks per month
Hence:
Credit union < Local bank
7 + 0.04x < 9 + 0.02x
Collect like terms
0.04x - 0.02x < 9 - 7
0.02x < 2
x < 2/0.02
x < 100 checks
Hence, writing less than 100 checks (i.e writing between 0 to 99 checks) makes the credit union a better deal.

f) graph the function in part e. (10 points)
Answers
Answer:
Step-by-step explanation:
Given: $1.99 as the fee per book (slope) & fixed fee of $3 (y-intercept)
The function can be written out f(x) = 1.99x + 3.
Express the value of f(x) for x = 0.
This would cancel out the slope, giving us a horizontal line on (0, 3).
f(0) = 1.99(0) + 3
f(0) = 3
You can try to graph the function using a software or by hand.
The graph is continuous because the x-values can have any input as a point.

You want to conduct a survey to determine the proportion of people who favor a proposed tax policy. How does increasing the sample size affect the size of the margin of error?
a. increasing n decreases E.b. increasing n increases E.c. increasing n will cause E to double in value.d. increasing n will not effect E.
Answers
Answer:
a. increasing n decreases E
Step-by-step explanation:
The sample size refers to the number (n) of units or observations taken from a population for a study. The results obtained from this sample size can be used to make generalizations about the entire population. The margin of error (E) is a measure of the sampling error or the percentage of the difference between the results obtained from the study and the true population value. The relationship between the sample size (n), and the Margin of error (E) is an inverse. That means
Sample size (n) ∝ 1/E
So, as the sample size increases, the margin of error decreases. This would be even more true if the accurate procedures for the experiment are followed.

Answers
Step-by-step explanation:
The given equation or expression is used to determine the total cost of buying carnival tickets.
the total cost is y
Also from the expression the cost of a ticket is $2.5
and x represents the number of tickets
now say x=5, that is 5 tickets, then the cost of buying the 5 tickets is given as
y=2.5(5)
y=12.5
Hence the cost of 5 tickets is $12.5
