Find the missing angle
Mila [183]

Answer:

55 degrees

Step-by-step explanation:

All angles in a triangle must equal 180 degrees when added together

They provide you with 2 angles 35 degrees and 90 degrees

So, you add 35 + 90 = 125

So you know that the 2 angles they give you equal 125 degrees

Now, you subtract 180 - 125 = 55

So the missing angle is 55 degrees

Jason wanted to place all 540 marbles in the 3 newly bought boxes. If he wants to
kotegsom [21]

Answer:

The first box will have 90 marbles, the second 180 and the third 270.

Step-by-step explanation:

Division in a ratio of 1:2:3

1 + 2 + 3 = 6

So

The first box will have 1/6 of the marbles.

The second box will have 2/6 = 1/3 of the marbles

The third box will have 3/6 = 1/2 of the marbles.

First box:

One sixth, so:

(1/6)*540 = 540/6 = 90

Second box:

One third, so:

(1/3)*540 = 540/3 = 180

Third box:

One half, so:

(1/2)*540 = 540/2 = 270

The first box will have 90 marbles, the second 180 and the third 270.

In an 18-meter race between a tortoise and a hare, the tortoise leaves 23 minutes before the hare. The hare, by running at an av
seropon [69]
We know that:
time=distance/speed
if the tortoise speed is x m/min, then since 0.5 m/hr=1/120 m/min
18/x=23+18/(x+1/120)
solving for x we get:
x=0.08 m/min
speed of hare is:
(0.08+1/120)=0.088 m/min
