Answer:
Step-by-step explanation:
[tex]d=vt-\frac{at^2}{2} \\ \\ a=\frac{2(d-vt)}{t^2} \\ \\ a=\frac{2(500-300(20)}{20^2} \\ \\ a=-27.5 \frac{m}{s^2}[/tex]
The acceleration of the tram is 1 m/s^2.
To find the acceleration of the tram, we can use the following equation:
acceleration (a) = (change in velocity) / (time taken)
First, let's convert the initial velocity to m/s:
Initial velocity = 300 m/minute
To convert to m/s, we need to divide by 60 (since there are 60 seconds in a minute):
Initial velocity = 300 m/minute ÷ 60 seconds/minute = 5 m/s
Now, let's find the final velocity. The tram travels a distance of 0.5 km in 20 seconds.
Distance traveled = 0.5 km = 500 m (since 1 km = 1000 m)
Time taken = 20 seconds
Now, we can find the final velocity (v) using the formula:
v = (change in distance) / (time taken)
v = 500 m / 20 seconds = 25 m/s
Next, we can find the change in velocity:
change in velocity = final velocity - initial velocity
change in velocity = 25 m/s - 5 m/s = 20 m/s
Finally, we can calculate the acceleration:
acceleration (a) = (change in velocity) / (time taken)
acceleration (a) = 20 m/s / 20 seconds = 1 m/s^2
So, the acceleration of the tram is 1 m/s^2.

Suppose your school costs for this term were $4780 and financial aid covered 3/4 of that amount. How much did financial aid cover? How much do you still have to pay?
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195

( iready math ) Macy's aunt makes raspberry jam using 6 tablespoons of sugar and 8 tablespoons of raspberries. What is the ratio of tablespoons of raspberries to tablespoons of sugar?
8 to 14
8 to 6
6 to 14
6 to 8
Answer:
8 to 6
Step-by-step explanation:
The question is asking what is the ratio of "tablespoons of raspberries" TO ratio of "tablespoons of sugars".
= 8 tablespoons of raspberries TO 6 tablespoons of sugar
= 8 (tablespoons of raspberries) TO 6 (tablespoons of sugar)
= 8 TO 6
The ratio of tablespoons of raspberries to tablespoons of sugar should be considered as the 8 to 6.
Calculation of the ratio:Since Macy's aunt makes raspberry jam using 6 tablespoons of sugar and 8 tablespoons of raspberries.
So here the ration be like
= 8 raspberries tablespoons to 6 tablespoons of sugar
= 8 to 6

Hassan plotted point M in the coordinate plane below.
On a coordinate plane, Point M is 0.5 units to the left and 0.25 units down.
He says that the plotted point is (0.5, 0.25). What is Hassan’s error?
The x- and y-coordinates are switched.
Both coordinates should be negative.
The x-coordinate should be -2.
The y-coordinate should be -1.
Answer:
Both coordinates should be negative
Step-by-step explanation:
When you go to plot a point, you always start at (0,0). Since you go left 0.5 units, that would put you at -0.5, then you go down 0.25 units which would put you at (-0.5, -0.25). The result would be (-0.5, -0.25). Hope this helps! :)

a=97
and a=x°(by corresponding angle)
x= 97°
x=b(by vertical opposite angle)
b = 97°

Answer:

Step-by-step explanation:
Hope this helped!
Answer:
a. 18 b. 15/64 c. 122 2/9 d. 157.5615 e. 19.8
Step-by-step explanation:
a.
b. multiply across, so 1 * 15 = 15, 4*16=64, 15/64 can't be reduced, so done
c. 13 3/4 * 7 8/9, you must convert to improper fractions to multiply
4*13+3 = 55 so the first part is 55/4, 7*9+8=80 so the second is 80/9
55/4 * 80/9 = (55*80) / (4*9) = 4400 / 36, both are divisible by 4 so can be reduced to 1100/9 which cannot be reduced any further, 1100 + 9 = 122 R 2 so
1100/9 = 122 2/9
d. used calculator
e. 33% of 60 = (33//100)*(60/1) = (33*60) / (100*1) = 1980 / 100 = 19.8

x = 70°, y = 30°, z = 20°
Step-by-step explanation:
Right triangle have a total internal angle of 180°.
x = 180° - 110°
= 70°
z = 180° - 90° - x
= 180° - 90° - 70°
= 20°
y = 180° - 40° - 90° - z
= 180° - 40° - 90° - 20°
= 30°

If the cost of manufacturing mobile phones is $10,000 for the factorytime plus $80 per phone and that each
phone sells for $100, how many phones must be manufactured for the mobile phone manufacturer to
break even (when costs equals revenue)?
Answer:
500 phones
Step-by-step explanation:
cost of manufacturing: y = 80x + 10,000
money from phone sales: y = 100x
* note: x = #phones
solve for when they're equal;
100x = 80x + 10,000
100x - 80x = 80x - 80x + 10,000
20x = 10,000 –––––––––––> divide both sides by 20
x = 500
