Answer:

B

Step-by-step explanation:

You see that the question mentions MPH. An hour is 60 minutes, so you would look at the 60 minutes on the base of the graph. If you go directly up to where the diagonal (dark) line perfectly crosses a point of the grid (that's any corner of any square on this grid) and look directly to the left (which represents the MPH) you see the number 3. If you go even higher, you see 6 MPH.

The 3 miles at 60 minutes represents 3 MPH, which is Tanisha's speed.

The 6 miles at 60 represents 6 MPH, which must be Albert's speed.

Since 6 is two times bigger than 3, the correct answer is B) Albert is running two times faster than Tanisha is walking.

Answer:

The final Price is: $75.14

Step-by-step explanation:

you first have to do -=- which means /105=35%/100

then you would do 105x35=3675/100=36.75

then Subtract 105-36.75=68.25.

The next step is to do -=- /68.25=10.1%/100

you would multiply 68.25 and 10.1 and get 689.325 the you would divided that by 100 and get 6.89325 then you would add 68.25 and 6.89325 and get 75.14.

Step-by-step explanation:

Billys mistake was when he multiplied the 80 by 12 instead of carrying the 1 from getting 160 from 80 x 2 he just put 16 and added 8 to it from 1 x 8.

Answer:

[tex]\huge\boxed{\sf v = 80\ mph}[/tex]

Step-by-step explanation:

Given Data:

Distance = S = 100 miles

Time = t = 1 1/4 hours = 1.25 hours

Required:

Speed = v = ? mph

Formula:

v = S/t

Solution:

v = 100 / 1.25

v = 80 mph

[tex]\rule[225]{225}{2}[/tex]

Answer:

27. My fiend solved the inequality correctly but graphed it incorrectly. The statement "x > 5" is correct but but since the symbol is "greater than" it should have been graphed with an open circle to the right rather than a closed circle to the right.

28. My friend is incorrect for both solving the inequality and graphing. The correct answer for solving the inequality would be "5 ≥ x ". And for graphing the correct answer would be closed circle to the right since the symbol is greater than.

Step-by-step explanation:

27. Solving the inequality

x - 7 > -2

+ 7 + 7

------- ------

0 5

answer: x > 5

Graphing the inequality

Since the symbol is greater than, it would be a open circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 28 the symbol is just greater than, not greater than or equal to.

28. Solving the inequality

8 ≥ x + 3

-3 - 3

-------- --------

5 0

answer: 5 ≥ x

Graphing the inequality

Since the symbol is greater than than or equal to, it would be a closed circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 27 the symbol is just greater than or equal to, not just greater than.

This might not be the right way to do it or the right answer for that matter, I am very new to solving and graphing inequalities so I just decided to give this one a shot.

Hope this helps ; )

Answer:

7 to the power of 7 ( which is 823,543 )

Step-by-step explanation:

Why? well if 4+3 is 7 the exponent would be 7 to because if you look carefuly it says with an exponent of 2 + 5 and 2 + 5 is 7 so your exponent is 7.

I hope This is right!

Answer: D

Step-by-step explanation: D is the incorrect

Answer:

4 2/21

Step-by-step explanation:

2/3 and 3/7 have a common denominator, 21

so, 14/21 and 9/21

plug in the whole numbers: 1 14/21 and 2 9/21

which will give you: 3 23/21

so, simplify it which will give u the answer: 4 2/21

Answer: 9:00 PM

Step-by-step explanation:

every 24 hours it will 4:00 PM again - so we do . . .  245 ÷ 24 = 10 days and 5 hours.  

so in 245 hours it will be 9PM

Answer:

This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.

Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus

AH +A = HEE

10A + H + A = 100H + 10E +E

11A + H = 100H + 11E

11A = 99H + 11E

A = 9H + E

As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

Step-by-step explanation:

The values of a function are the true values of the function.

The value of x is 5

The functions are given as:

When x = 2 to 6, we have:

When x = 2 to 6, we have:

By comparison:

So, we have:

Hence, the value of x is 5

[tex]m = slope\\(x1, y1) = coordinates of first point in the line\\(x2, y2) = coordinates of second point in the line[/tex]

Answer:

I don’t know the answer but I can try to help.

Step-by-step explanation:

The slope is the measurement of the steepness of a line, so all you would have to do is find the steepness of the line on that graph.

2. 277

Step-by-step explanation:

I'm not too sure which answer you're looking for but I'll try to answer all of them :).

First of all, we can consider them in percentage form first.

If the first sale price is marked down by 30%, it is now 70%.

For the second, the price is marked down by 20% first, so 80%.

And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.

As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price

Now we move on to the actual prices.

First one is 70% of the original price, 70% of $385 is $269.5.

Second one is 72% of original price, 72% of $385 is $277.2

Don't forget to round to the nearest dollar!

Step-by-step explanation:

Backpack 2 is 2x, 2y, so double each number:

(0,2) = (0, 4)

(8,2) = (16, 4)

(6,5) = (12, 10)

(2,5) = (4, 10)

(0,2) = (0,4)

Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:

(0,2) = (8, 0)

(8,2) = (16, 0)

(6,5) = (14, 3)

(2,5) = (10, 3)

(0,2) = (8, 0)

Backpack 4 is x, 2y, so keep the same x and multiply y * 2

(0,2) = (0, 4)

(8,2) = (8, 4)

(6,5) = (6, 10)

(2,5) = (2, 10)

(0,2) = (0,4)
