Answer:

To understand this, bags of gas added make it go up, while bags of sand added make it go down:

1). Add bags of gas | balloon goes UP | 3 bags of gas ( +3 ), 10 bags of sand ( +10 )

2). Add bags of sand | balloon goes DOWN | 3 bags of sand ( -3 ), 10 bags of sand ( -10 )

3). Subtract bags of gas | balloon goes <u>DOWN</u> | subtract 3 bags of gas <u> </u><u>-</u><u> </u>(<u> </u><u>+</u><u>3</u><u> </u>), subtract 10 bags of gas <u> </u><u>-</u><u> </u>(<u> </u><u>+</u><u>1</u><u>0</u><u> </u>)

4). Subtract bags of sand | balloon goes <u> </u><u>U</u><u>P</u><u> </u> | subtract 3 bags of sand <u> </u><u>-</u><u> </u>(<u> </u><u>-</u><u>3</u><u> </u>), subtract 10 bags of sand <u> </u><u>-</u><u> </u>(<u> </u><u>1</u><u>0</u><u> </u>)

11. In AWTY, if mZW is five less than twice mZY and mZX is 21 more than m_Y find the measure
wolverine [178]

9514 1404 393

Answer:

  angles (W, X, Y) = (77°, 62°, 41°)

Step-by-step explanation:

<u>Given</u>:

  ΔWZY

  ∠W = 2(∠Y) -5°

  ∠X = ∠Y +21°

<u>Find</u>:

  ∠X, ∠Y, ∠W

<u>Solution</u>:

Using angle measures in degrees, we have ...

  ∠X + ∠Y + ∠Z = 180

  (∠Y +21) +∠Y + (2(∠Y) -5) = 180

  4(∠Y) +16 = 180 . . . . . simplify

  ∠Y +4 = 45 . . . . . . . . . divide by 4

  ∠Y = 41 . . . . . . . . . . . . subtract 4

  ∠W = 2(41) -5 = 77

  ∠X = 41 +21 = 62

The angle measures of angles (W, X, Y) are (77°, 62°, 41°), respectively.

A rectangle and a triangle with the same base and height have the same area.
OverLord2011 [107]
The answer is false because if you attach to triangles together in a way so that the figure would have 4 straight lines, you will get a rectangle. that means half of a rectangle is a triangle, so the area of both cannot be the same even if they have the same base and height.


for example the base and height of both is 3cm and 5cm.

area of the rectangle then would be,
area= base× height
=3cm×5cm=15cmsquared

then the area of the triangle would be,
area= base×height divided by 2
=3cm×5cm÷2= 7.5cm

so your answer is false
hope this helps....

A teacher has 3 hours to grade all the papers submitted by the 35 students in her class. She gets through the first 5 papers in
RideAnS [48]

Let us calculate the teacher's initial speed. It can be calculated as thus:

She does 5 papers in 30 minutes. Thus means her speed is 6 minutes per paper (Because \frac{30}{5}=6 minutes per paper).

Now, if the teacher has to complete the remaining 30 papers in the remaining 150 minutes (2 hours 30 minutes=120+30=150 minutes), she will have to go through one paper in \frac{150}{30}=5 minutes. Thus, her speed now will have to be 5 minutes per paper.

Now, we know that 1.2 times 5=6. Therefore, it will not be wrong to say that '' she has to be 1.2 times faster instead of 20% faster" because both mean the same.
