Mathematics
1 answer:
Illusion [34]3 years ago
7 0

Answer:

25

Step-by-step explanation:

Given,

Measurement of <1 = x + 10

Measurement of <2 = 4x + 5

Also, said in the question that both these angles are complementary.

Therefore, by the problem,

<1 + <2 = 90°

=> x + 10 + 4x + 5 = 90

=> x + 4x + 10 + 5 = 90

=> 5x + 15 = 90

=> 5x = 90 - 15 = 75

=  > x =  \frac{75}{5}

=> x = 15

Now, we have got the value of x so,

Measurement of <1 is

<1 = x + 10 = 15 + 10 = <u>25 (Ans)</u>

Half of a sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The he
Flauer [41]

Answer:

312π mm^2

Step-by-step explanation:

to find the volume of the figure, you have to calculate the volume of a cone and the volume of a sphere divided it by 2.

The volume of a cone is 1/3 * π * r ^ 2 * h, replacing the information:

V = 1/3 * (6) ^ 2 * (14) = 168π  mm^2

The volume of a sphere is 4/3 * π * r ^ 3, replacing the information:

V = 4/3 * π * (6) ^ 3 = 288π  mm^2

but since you only have half the sphere

V = 288π / 2 = 144π  mm^2

then the total volume is

Vt = 168π + 144π = 312π mm^2

WINSTONCH [101]

Answer:  \frac{2}{35}

Step-by-step explanation:

Given: The total number of ways of to choose 3 contestants out of 7 (including me and my friend)=35..................> Total outcomes.

Favorable outcomes = 2

Then the probability that me and my friend are both chosen =\frac{\text{favorable outcomes }}{\text{Total outcomes}}

Thus , the probability that me and my friend are both chosen =\frac{2}{35}

Ball B, with a mass of 30kg, is moving to the left at -10 m/s. With what velocity should Ball A, with a mass of 10 kg, move to t
tangare [24]
Initially, Ball A of 10 kg will have velocity x, while Ball B of 30 kg has velocity -10 m/s.
After collision, Ball A will have a velocity of -30 m/s, while Ball B will have velocity 10 m/s. We assume their masses do not change.
(10 kg)(x m/s) + (30 kg)(-10 m/s) = (10 kg)(-30 m/s) + (30 kg)(10 m/s)
10x - 300 = -300 + 300
x = 30 m/s (to the right)
