The track team needs new uniforms. the students plan to sell candies. the students find three companies for 44.80. company c charges
Answer: Answer:
Company C
Step-by-step explanation:
Company A sells 12 tigers for $33.24.
Cost per tiger = $33.34 / 12
= $2.78
Company B sells 16 tigers for $44.80. Company
Cost per tiger = $44.80 / 16
= $2.8
C charges $41.10 for 15 tigers.
Cost per tiger = $41.10 / 15
= $2.74
The company that has the best buy is company C that charges $2.74 per tiger

Answer:
6x - 4
Step-by-step explanation:
Cross out the 3 in the denominator and the 9, which simplifies to 2 times 3x, which is 6x. For the second part, cross out 3 in the denominator and -6, which becomes 2 times (-2), which is -4.
c) A bus completes its journey in 14 hours with an average speed of 40 km per hour. How long does the bus take to complete the journey if its average speed is increased to 56 km per hour?
Explanation:
Compute the distance for the original speed and time
distance = rate*time
distance = (40 kph)*(14 hrs)
distance = 560 km
If we increase the rate or speed to 56 kph, then,
distance = rate*time
560 km = (56 kph)*x
560 = 56x
56x = 560
x = 560/56
x = 10
The bus will travel for 10 hours if its speed is increased to 56 km per hour.
Answer:
A bus takes 4.5 hours to complete a complete a journey at a speed of 40km/hr
So, in this case, We will find the distance first because the distance is constant.
distance-speed*time
distance=40*4.5
distance=180km
distance=180km
Now, we find the time to cover the distance at the speed of 45km/hr
time distance/speed
time=180/45
time=4hrs
Therefore, the answer is 4hrs

Emily received a check from her grandmother for $40.00 for her birthday. To cash the check, her bank requires her to deposit the funds into her account. Since she wanted to spend the money that afternoon, she withdrew $40.00 in the same transaction. Jacoby went on a hiking trip on the Rocky Bend Loop. Starting at an elevation of 1,200 feet, he hiked up the eastern trail leading to a change in elevation of 782 feet to get to the campsite. The next day he hiked down the western trail which had a change in elevation of 782 feet to get back to his car. During the top of the fourth inning of a baseball game, the Ravens scored three runs.

10-3•2/1+1 what is the answer???
Answer:
5
Step-by-step explanation:
PEMDAS ( or for whatever one you do... )
You read it from left to right. So, whatever comes first you do then you continue.
Multiplication came BEFORE division in this case.
3 x 2 = 6
Then Division.
You had gotten 6 FROM 3 x 2. Divide that TOTAL with 1.
6/1 = 6
[ Then subtraction is infront of addition. It may seem confusing but regardless how the letters are formatted in "PEMDAS" you ALWAYS read from left to right. "PEMDAS" has Addition infront of Subtraction but in this case, subtraction goes first because it's infront of the addition. ]
Then you subtract.
You had gotten 6 FROM 3x2/1
Subtract that TOTAL with 10. 10 - 6
What is 10 - 6? 4 because 10 is LARGER than 6
Then you add.
You got the TOTAL of 4 FROM 10-3x2/1.
Add that TOTAL with 1.
4 + 1 = 5.
The answer should be 5 but correct me If I'm wrong.

7) In an old episode of the TV program McGyver, a planeload of gold was being transported from the SovietUnion to the United States during WWU. The place crashed in the Arctic region. To prevent the "badguys" from getting the gold, the pilot and copilot transferred the gold into a cave by stacking it on a door
of the crashed plane and dragging the "sled" into the cave. You were led to believe in the episode that
they accomplished the move in one trip. The gold was stacked neatly in the shape of a cube, measuring
about 1 meter on a side. Calculate the weight, in tons, of one cubic meter of gold. The density of gold is
19.4 g/cc. Would it have been possible for the two pilots to accomplish this feat? Would a plane of WWII
vintage be able to carry this much gold? (cc = cubic centimeter, 1cm = 1mL)
Here we need to remember that:
density = mass/volume
Only by using this equation, we will find that the mass of gold is 19,400 kg
In this case, we know that the gold is in the shape of a cube with side length of one meter.
Remember that for a cube of side length L, the volume is:
V = L^3
Then in this case, the volume of the cube of gold will be:
V = (1m)^3 = 1m^3
And we know that the density of the gold is:
density = 19.4 g/cc
cc = cm^3
density = 19.4 g/cm^3
Notice that we have different units of volume, so we would want to write the volume in cm^3
We know that:
1m^3 = (1×10^6)cm^3
Then the volume of the cube of gold is just:
V = (1×10^6)cm^3 = 1,000,000 cm^3
Now let's return to the density equation:
density = mass/volume
Solving for the mass, we get:
density×volume = mass
Now we can replace the two things in the left side:
(19.4 g/cm^3)×(1,000,000 cm^3) = mass = 19,400,000 g
Now remember that:
1000k = 1kg
Then we can rewrite:
mass = 19,400,000 g = (19,400,000/1000)kg = 19,400 kg
So the cube of gold has a mass of 19,400 kg, there is no way that two persons could carry this much gold into a cave.

Collinear points lie on the same line. Find the value of k for which the following points are collinear: (k,3), (-3,2), (-1,1)
Answer:
k=-5
Step-by-step explanation:
For the points to be collinear any two pair must have the same slope
We find the slope of the 2nd and 3rd points
=1-2/-1--3
=-1/2
Now finding the slope of the 1st and any other point say point 3
1-3/-1-k=-½
-2/-1-k=-½
-4=-1(-1-k)
-4=1+k
k=-4-1
k=-5
PROOF
if the first point is (-5,3)
slope of point 1 and 2
=2-3/-3--5
=-1/2
