Answer:
$58.50
Step-by-step explanation:
1.2 kg = 1200g
To get from 200 to 1200, we time 6, so we take $9.75 times 6 to get the price.
$9.75 times 6 = $58.50
So, the cost of 1.2kg cheese is $58.50
The answer is $58.50

Javier and his friends go out to eat. The restaurant they chose automatically adds a 15% gratuity to their food bill since they are a party of 12. The total bill after the automatic 15% gratuity was $213.90. Because they received such good service, the group decided to add an extra $20 to the total bill as an additional tip.
So, instead of leaving a 15% tip, Javier and his friends ended up leaving a tip that was about _% of the food bill.
Which is the most accurate way to estimate 34% of 85?
A: 1/3 x 81
B: 1/2 x 81

Answer:
(5+3^2)*4
Step-by-step explanation:
i belive im correct
Olivia ran 56 miles last month.
What is the expression?
Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
Given,
She ran 5 days during the first week of the month
She ran only 3 days each week for the next 3 weeks.
Number of mile she ran given by expression (5 + 3 * 3) * 4
= (5 + 9) * 4
= 1 4 *4
= 56

The average mass of 5 man basketball team is 70Kg. Four of team members have a mass of 50kg, 62kg, 81kg, and 84kg What is the mass of the fifth player???? 15 POINTS!!!
Answer:
The mass of the fifth player is 73 kg
Step-by-step explanation:
Since the average mass of the 5 players is 70kg
what this mean is that the total sum of all the masses of the players is equal to the product of 5 and 70 kg
we have this as 5 * 70kg = 350 kg
So, by adding the masses of all the players, we get 350kg
Thus, for us to get the mass of the 5th player, we have to subtract the sum of the remaining 4 from the total 350kg
Mathematically, we have this as;
350 - ( 50 + 62+ 81 + 84) = 73 kg
what is 10c + 20 = 40 C =
Answer: c = 2
Step-by-step explanation:
First you write out your equation: 10c + 20 = 40
Next, since the equation is adding, you can subtract 20 the constant on both sides of the equation:
10c + 20 = 40
- 20 - 20
The 20s cancel each other out and 40 - 20 is 20.
Our new equation looks like: 10c = 20
Now to find the value of C you are going to divide 10 on both sides because the equation is multiplying.
10c divided by 10 is just c and 20 divided by 10 is 2.
Therefore, you are left with c = 2

Answer:
B. (2, 1)
Step-by-step explanation:
As a first guess you might say the right angle will be at the point that has the x-coordinate of A (2) and the y-coordinate of B (1).
You notice that the point (2, 1) is on the list of answer choices, so that is a good choice.
The coordinates of C could be (2, 1).

A boat covers 25 km upstream and 44 km downstream in t hours. Also, it covers 15 km upstream and 22 km downstream in 5 hours. Find the speed of the boat in still water and that of the stream.
9514 1404 393
Answer:
boat speed: (7t -95)/(6t² -110t +500)
stream speed: (37t -345)/(6t² -110t +500)
Step-by-step explanation:
The relation between time, speed, and distance is ...
time = distance/speed
The boat speed (b) is added to the stream speed (s) going downstream. The stream speed is subtracted going upstream. The given relations tell us ...
25/(b-s) +44/(b+s) = t
15/(b-s) +22/(b+s) = 5
This gives us 2 equations in 3 unknowns, so we can only provide a solution in terms of one of the unknowns. Since we are asked for the speeds, they will be provided in terms of t.
Subtracting the first equation from 2 times the second gives ...
2(15/(b-s) +22/(b+s)) -(25/(b-s) +44/(b+s)) = 2(5) -(t)
5/(b-s) = 10 -t
5/(10 -t) = b -s
Substituting for b-s in the second equation gives ...
15/(5/(10-t)) +22/(b+s) = 5
30 -3t +22/(b+s) = 5
22/(b+s) = 3t -25
22/(3t -25) = b+s
Adding the equations for the sum and difference of speeds, we get ...
(b-s) +(b+s) = 5/(10-t) +22/(3t -25)
2b = (5(3t -25) +22(10 -t))/((10-t)(3t-25)) = (95 -7t)/((10-t)(3t-25))
b = (7t -95)/(6t² -110t +500)
Subtracting the equations for sum and difference of speeds, we get ...
(b+s) -(b-s) = 22/(3t -25) -5/(10 -t)
2s = (22(10-t) -5(3t -25))/((10-t)(3t-25))
s = (37t -345)/(6t² -110t +500)
__
The speed of the boat in still water is (7t -95)/(6t² -110t +500) km/h.
The speed of the stream is (37t -345)/(6t² -110t +500) km/h.
__
Note that these solutions only make sense for values of t between 25/3 and 345/37, approximately 8.33 < t < 9.32. For t=9 hours, the boat speed is 8 km/h and the stream speed is 3 km/h.

The area of triangle QTU is 6 square units, and the area of triangle RSU is 6 square units. The dimensions in the figure below are labeled in units. What is the area of triangle STU in square units
Answer:
The area of a triangle is 1/2BH, or 1/2 times the base times the height.
If the area = 6, and B and H must both be whole numbers.
The area of the triangle ΔSTU is given by A = 12 units²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle ΔSTU be represented as A
Now , the area of triangle ΔQTU is 6 square units, and the area of triangle ΔRSU is 6 square units
So , the base of the triangle ΔSTU = 6 units
The height of the triangle ΔSTU = 4 units
So , area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
The area of triangle ΔSTU = ( 1/2 ) x 4 x 6
The area of triangle ΔSTU = 12 units²
Therefore , the value of A is 12 units²
Hence , the area of the triangle is 12 units²

Gina subtracted 6 8 from 1 and found a difference of 2 8 . Which statement best describes the difference of 6 8 from 1 is 2 8 ? F The difference of 2 8 is not reasonable because 1 – 3 4 = 1 4 . G The difference of 2 8 is reasonable because 3 4 – 1 4 _ = 1 2 . H The difference of 2 8 is reasonable because 1 – 3 4 = 1 4 . J The difference of 2 8 is not reasonable because 3 4 – 1 4 = 1 2 .
Answer:
Statement H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .
Step-by-step explanation:
Given - Gina subtracted 6/8 from 1 and found a difference of 2/8 .
To find - Which statement best describes the difference of 6/8 from 1 is 2/8 ? Statement F : The difference of 2/8 is not reasonable because 1 – 3/4 = 1/4 .
Statement G : The difference of 2/8 is reasonable because 3/4 – 1/4 = 1/2 .
Statement H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .
Statement J : The difference of 2/8 is not reasonable because 3/4 – 1/4 = 1/2 .
Proof -
If we subtract 6/8 from 1 , we get
[tex]1 - \frac{6}{8} = \frac{8 - 6}{8} = \frac{2}{8}[/tex]
So, the difference is 2/8
It is reasonable.
So,
The correct statement is - Statement H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .
Reason -
As we can write
[tex]\frac{6}{8} = \frac{3}{4}[/tex] and [tex]\frac{2}{8} = \frac{1}{4}[/tex]
So,
either we subtract 6/8 from 1 or 3/4 from 1 , we get the same result because both the values are equal
So the correct statement is - H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .

15 in.
What is the surface area of this solid?
square inches
Answer:
The answer is "[tex]\bold{1920 \ in^2}[/tex]".
Step-by-step explanation:
Please find the graph file.
Rectangular solid area:
Its region comprises four rectangles, each 15 for each case 14 in each.
The rectangle field is the formula [tex]A = lw[/tex]
The four rectangles are therefore covered by a zone: [tex]\to A = 4lw = 4 \times 15 \ in \times 14 \ in = 840 \ in^2.[/tex]
square Pyramids area:
The pyramids in both squares have 8 triangular facets.
Each triangle has a 15-inch basis with a 14-inch base.
The triangle zone formulation is [tex]A = \frac{1}{2}bh[/tex]
That's it. The 8 triangles area is [tex]\to A = 8 \times \frac{1}{2}bh = 4bh = 4 \times 15 \ in \times 18 \ in = 1080 \ in^2[/tex]
Total field surface:
Strong rectangular[tex]= 840 \ in^2[/tex]
Pyramids in the Square[tex]= 1080[/tex]
Overall area [tex]= 1920 \ in^2[/tex]
The number is [tex]1920\ in^2[/tex] for a total area.
