1 answer:
son4ous [18]3 years ago
6 0

Answer:

\frac{1}{8}

Step-by-step explanation:

The probability for a flip on either side of the coin is always 50% or \frac{1}{2}

So to get the probability for the three flips just do:

(\frac{1}{2}) ^{3}  or \frac{1}{2} × \frac{1}{2} × \frac{1}{2}

Either way you solve it the answer is \frac{1}{8}

One number is 7 more 3 times another number. the sum is 75. what is the smaller number
NeTakaya

Greetings from Brasil...

According to the statement of the question, we can assemble the following system of equation

X = 7 + 3Y i

X + Y = 75 ii

So, multiplying ii by -1 and adding with i

X = 7 + 3Y

- X - Y = - 75

- Y = 7 + 3Y - 75

4Y = 68

Y = 17

for X we will use ii:

X + Y = 75

X + 17 = 75

X = 58

The smaller number is: 17

Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units. The larger triangle's longest side is 52
Firdavs [7]

Answer:

117 units

Step-by-step explanation:

if you use the ratio of the two longest sides then you can find all side lengths

\frac{52}{20} = \frac{x}{10};    x = half of 52, or 26

\frac{52}{20} = \frac{x}{15};    20x = 52 · 15

              20x = 780

               x = 39

add to get perimeter: 52 + 26 + 39 = 117 units
