Solve: a+1/3+a-1/5=2/15

Mathematics
1 answer:
xeze [42]3 years ago
8 0

Answer:

a=0

Step-by-step explanation:

<u>Step 1:</u>-

Given a+\frac{1}{3} + a - \frac{1}{5} = \frac{2}{15}

on simplification we get,finding l.c.m

2 a + \frac{5-3}{15} =\frac{2}{15}

2 a+\frac{2}{15} = \frac{2}{15}

subtracting \frac{2}{15} on both sides,and cancelled then we get

solution is

2 a=0

a=0

Assuming we have an upward-facing parabola describe the location of the vertex in relation to the x-axis (above, below, or on th
goldfiish [28.3K]

Answer:

a. Negative discriminant: above  

b. Positive discriminant:  below

c. Discriminant is zero: on

Step-by-step explanation:

If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis

If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis

If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis

Convert into a decimal degree measure. 165° 37' 44"
andrew11 [14]

Answer:

165.628° (The 8 has a line over it signalizing that it repeats forever, but I didn't know how to put it in.)

Step-by-step explanation:

Since 165 is whole number, it is a full degree. Since each minute is equal to 1/60 degrees, you need to multiply 37 by 1/60. Since each second is equal to 1/3600 degrees, multiply it 1/3600 by 44. Add them all together.

165 + 37 x 1/60 + 44 x 1/3600

simplify: 74533/450

Convert the fraction into a decimal by dividing the numerator by the denominator and you get 165.628° (with a repeating 8).

A disc of unit radius is tossed at random onto a large rectangular floor, which is tiled with $4 \times 6$ tiles. Find the proba
goldenfox [79]

Answer:

1/3

Step-by-step explanation:

In order for the disc to be entirely contained in a rectangular tile, its center must be at least 1 unit from the nearest edge.  Which means there's a 2 by 4 region that the center can lie in.

So the probability is (2×4) / (4×6) = 8/24 = 1/3.
