What is the sum of 6/13 and 1/8. why is the sum greater then 1/2

1 answer:

8 0

The lcm is 104
so
48/104+13/104
=61/104
since it is converted to decimal form
61/104=.59

its greater than 1/2 because 1/2 is only .5

A coin is tossed 3 times. What is the probability that the number of tails obtained will be between 1 and 3 inclusive?

LekaFEV [45]

Answer: $\dfrac{7}{8}$

Step-by-step explanation:

Given : When a coin is tossed twice , the total outcomes will become

HHH , HHT , HTH , THH , TTH , THT , HTT ,TTT

Total outcomes = 8

Favorable outcomes to obtain 1 and 3 inclusive = HHT , HTH , THH , TTH , THT , HTT ,TTT

Number of favorable outcomes = 7

Probability that the number of tails obtained will be between 1 and 3 inclusive = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

$=\dfrac{7}{8}$

Hence, the probability that the number of tails obtained will be between 1 and 3 inclusive $=\dfrac{7}{8}$

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angl

Dmitry_Shevchenko [17]

Answer:

The value of x is 50°.

Step-by-step explanation:

We know that:

x = y
2(70 + 60) + x + y = 360

Work:

2(130) + x + x = 360
=> 260 + 2x = 360
=> 2x = 360 - 260
=> 2x = 100
=> x = 50

Hence, the value of x is 50°.

Hoped this helped.

How does 17- (-15) compare to 17-0

pentagon [3]

17-(-15)=32
17-0=0
They are not equivalent so they are different.
Also for future reference when you have 2 minus signs they equal a addition sign.
Hope this helps :) GL

If the coordinates for C' are (4.5, 4.5), which rule best represents the dilation that was applied to rectangle ABCD to create r

Dmitry_Shevchenko [17]

The dilation of rectangle ABCD to create rectangle A'B'C'D' would change the size of the rectangle

The dilation rule is: (x,y) -> k(x,y)

<h3>How to determine the rule of dilation?</h3>

The coordinates of C' is given as:

C' = (4.5, 4.5)

The coordinate of point C is not given.

So, I will apply a general rule

The general rule of dilation is:

(x,y) -> k(x,y)

Where k represents the scale factor.

Assume that k = 3, the the rule would be
(x,y) -> 3(x,y)
