Mathematics

8 0

Answer:

x = 8

Step-by-step explanation:

If the number 212x5 is a multiple of 3, the sum of the digits needs to be a multiple of 3, so we have:

2 + 1 + 2 + x + 5 = 10 + x

The value of x can be 2, 5 or 8

If the number is a multiple of 11, we have to calculate the first number minus the second, plus the third, minus the fourth... and so on, and the result needs to be a multiple of 11. So we have:

2 - 1 + 2 - x + 5 = 8 - x

x needs to be 8, so we have 8 - 8 = 0, that is a multiple of 11.

So the value of x is 8.

Find the approximate volume. Round to the hundredth when necessary.
Alika [10]

Answer:

Step-by-step explanation:

1: Base Surface Area =  π×72

=  153.9380400259 millimeters2

Lateral Surface Area =  π×7×√72 + 142

=  344.215921821 millimeters2

Total Surface Area = 498.1539618469 millimeters2

Rounded = 500 millimeters2

2:Base Surface Area =  π×52

=  78.539816339745 centimeters2

Lateral Surface Area =  π×5×√52 + 102

=  175.62036827602 centimeters2

Total Surface Area = 254.16018461576 centimeters2

Rounded 300 centimeters2

Solve for each indicated angle measure or variable in the figure.<br> m x
Elis [28]
If vertical angles are congruent you know

84=4x
21=x

You also know that angle M is supplementary to the angle
, measuring 84. Supplementary means it adds to 180 so if you take the difference you get

180-84=M
96=M


Also M is vertical to the last unknown angle so since vertical angles are congruent the last angle is also 96
