Answer:
B. What was the highest temperature this month?
Step-by-step explanation:
Rory is recording the highest temperature for the duration of the day for month's worth of data.
B. is the easiest one to answer, as you simply will have to look for the greatest number within the set, and that will be the answer.
A. is too broad, and does not imply that only the "high temperature" is needed, rather just a leveled temperature within day in that month.
C. is the opposite of what Rory had recorded, and without data, he cannot answer it.
D. is answerable as well, but, again, the only temperature recorded is the high temperature. Temperature can fluctuate depending on the time of the day, and can be in the 50s one hour and the 90s in another.

Portia has purchased a new aquarium for her fish. It is in the shape of a hexagonal prism. 3a) How much water can Portia’s new aquarium hold? * 1 point a) 166.28 cubic inches b) 790.28 cubic inches c) 956.56 cubic inches d) 3120 cubic inches e) 6240 cubic inches
Answers
Answer:
D. 3120
Step-by-step explanation:
How many sides does a hexagon have? Six. Let's begin our equation with 6. The area of a triangle formula would be: 1/2 bh. And a hexagon is just six triangles put together. Now our equation is: 6 (1/2 bh) What's bh then? B (base)= 8in. The base is usually always at the bottom. Now we take 10 and add it into the equation. Next we would multiply this by 13. Our equation is now: 6(1/2*8*10)*13. What do you get then? 3120.
For Part B: Portia's new fish require complete darkness for 12 hours a day. Rather than buying a blackout curtain for her room, she decides to make an aquarium cover out of a tropical print, with a blackout liner. How much tropical print fabric will she need to purchase in order to cover the top and sides of the aquarium?
Now, we're dealing with surface area. What is surface area, anyway? Surface area is the sum of all faces. There are 2 hexagonal faces and 6 sides.
What is 6*1/2 *8? 24! Now what's 10*24? That's right, 240!
8*13=104
6(104)=624
624+240=864

What linear equation is represented by the table?

Best answer gets Brainliest!!!!
A) Y= 2x
B) y= 4x
C) y= 4x -2
D) y= 2x - 2
Answers
Answer:
y = 4x - 2
Step-by-step explanation:
linear equation - y = mx + b
where m = slope and b = y intercept
The y intercept is the y value of the coordinate where x = 0
Looking at the table, we notice that when x = 0, y = -2
Which means that the y intercept ( b ) = -2
Slope = change in y over change in x
As y goes up 4 x goes up 1
Thus, slope ( m ) = 4
Now we plug in the identified slope and y intercept into " y = mx + b "
we get that the equation is y = 4x - 2
Sorry if it’s incorrect but that is the answer I think is correct
Suppose that a regression line for some data transformed with logarithms predicts that when x equals 7. logi) will equal 1.755. What does the regression line predict y will equal when xequals 7? Round your answer to the nearest whole number A. 57 O OB. 12 Oc. 2 O D. 30
Answers
Answer:
A: 57
Step-by-step explanation:
We are told that;
When x = 7, log y = 1.755
Since we want to find the value of y when x = 7, and the log function is in base 10, we will just use anti log to solve for y in the equation.
Thus;
Log₁₀y = 1.755
y = 10^(1.755)
y = 56.89
Approximating to a whole number gives;
y = 57

Rob can complete his bus route in 4 hours. Joan can complete her bus route in 3 hours. If they both left the terminal at 3:00 am and after each completed route returned to the terminal, determine the next time they would leave the terminal at the same time.
Answers
Answer:
3:00 pm
Step-by-step explanation:
Given
[tex]Rob = 4\ hrs[/tex]
[tex]Joan = 3\ hrs[/tex]
[tex]Start\ Time = 3:00\ am[/tex]
Required
The next time they leave at the same time
To do this, we first list out the multiples of 4 and 3 (i.e. their time of completing each route)
So, we have:
[tex]Rob: 4, 8, 12, 16, 20...[/tex]
[tex]Joan: 3,6,9,12,15,18....[/tex]
The least common multiple in the above is:
[tex]Least = 12hrs[/tex]
This means that they will meet at the terminal after 12 hours
So, their meeting time is:
[tex]Time = 3:00am + 12\ hrs[/tex]
[tex]Time = 3:00\ pm[/tex]

Which Which value of x makes this equation true? -3x+10=5x-8
value of x makes this equation true? -3x+10=5x-8
Answers
Answer:
9/4
Step-by-step explanation:
-3x+10=5x-8
or, -3x-5x = -8-10
or, -8x=-18
or, 8x=18 (i.e. - is cancelled)
or, x=18/8
i.e. x=9/4
Hence, the value of x is 9/4
Answer:
The value of x is 9/4
Step-by-step explanation:
-3x+ 10 = 5x - 8
Add 3x both side
-3x + 3x + 10 = 5x + 3x - 8
10 = 8x - 8
Now, Add 8 both side
10 + 8 = 8x - 8 + 8
18 = 8x
8x = 18
Now, Divide by 8 from both side
8x/8 = 18/8
x = 9/4
Thus, The value of x is 9/4
FOR VERIFICATION ONLY:-3x + 10 = 5x - 8
-3(9/4) + 10 = 5(9/4) - 8
-27/4 + 10 = 45/4 - 8
-27 + 4 × 10/4 = 45 - 8 × 4/4
-27 + 40/4 = 45 - 32/4
13/4 = 13/4
Hence, L.HS = R.H.S

The graph above shows the cost, in dollars, of apples as

compares the cost per pound of apples and the cost per
pound of pears at this store?
A. Apples cost approximately $0.07 less per pound
than pears do.
B. Apples cost approximately $0.04 less per pound
than pears do.
C. Apples cost approximately $0.73 less per pound
than pears do.
D. Apples cost approximately $0.62 more per pound
than pears do.
Answers
Your answer is A
The accurate statement is A. Apples cost approximately $0.07 less per pound.
Cost of Apples per pound using the given graph:The constant of proportionality would give us the cost of per pound. From the graph, when number of pounds (p) = 3, cost in dollars (C) = 4.
Constant of proportionality = C/p = 4/3
Therefore, Cost of apples per pound = 4/3 = $1.33 (approximated)
Cost of Pears per pound using the given equation:[tex]C = \frac{7}{5} p[/tex]
The constant of proportionality of the equation function will give us the cost per pound for pears.
From the equation, the we can deduce that [tex]\frac{7}{5}[/tex] represents the cost of pears per pound (constant of proportionality).
Thus:
Cost of pears per pound = 7/5 = $1.40
The difference between the cost per pound of pears and the cost per pound of apples would be:
$1.40 - $1.33 = $0.07
Therefore, we can conclude that apples cost approximately $0.07 less per pound.
