Answer:

this makes no sense

Step-by-step explanation:

The number that when multiplied by 3, equals the sum of the number and 5 is 2.5.

First assume that the number we are looking for is x.

One side of the equation will be:

= 3 × x

= 3x

The other side of the equation would be:

= 5 + x

Equating these numbers gives:

3x = 5+ x

3x - x = 5

2x = 5

x = 5/ 2

x = 2.5

In conclusion, the number is 2.5.

4ft*4 1/3ft*3 1/3ft = 57 7/9 ft3

Answer:

Both are 1/2

Step-by-step explanation:

Count just the tails, that's the numerator

Count all the heads and tails, that's the denominator.

And for the 2nd fraction:

Count just the evens, that's the numerator

Count all the even and odd numbers, that's the denominator.

Answer: The answer to this question is 3/4

Step-by-step explanation:

In this problem, there are 12 outcomes. Of those, 3 result in an even number and a tail, 3 more in an even number but not tail and 3 in a tail but an odd number, hence there are 9 desired outcomes.

Hence, the probability is given by: p=9/12=3/4

Answer:

See below.

Step-by-step explanation:

Each term increases by 3 for A and 4 for B.  Either do this calculation manually on a table, or use a spreadsheet to calculate all terms quickly.

The ten first terms for A and B are shown.  

A B Difference

1 1 1    0

2 4 5    1

3 7 9    2

4 10 13    3

5 13 17    4

6 16 21    5

7 19 25    6

8 22 29    7

9 25 33    8

10 28 37    9

We can see that the difference between the two patterns is that B increases more rapidly until there is a difference of 9 by the 10th term.

Answer: Translation, reflection, rotation

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

1 / secA+tanA =  1 / [1/cosA+sinA/cosA))]

= 1/ [(1 + sinA)/cosA]

= cosA/(1+sinA)

Now check if this is identical to 1-sinA/cosA:

1-sinA/cosA = cosA/(1+sinA)

Cross multiply:

(1-sinA)(1+sinA) = cos^2A

1 - sin^2A = cos^2A

sin^2A + cos^2A = 1  

This is a known idenity.

So the original identity is true.

Area of one face = 1/2 x base x height = 1/2 x 5 x 3 = 7.5 square inches.

there are 3 of those faces : 7.5 x 3 = 22.5 square inches.

the bottom triangle = 1/2 x 5 x 4.3 = 10.75 square inches

total surface area = 22.5 + 10.75 = 33.25 square inches

Answer:

T9 = 5/256

Step-by-step explanation:

You can tell it by looking at the pattern of the progression whether each term +- or ×÷.

From the question,

First term, a = 5

Common ratio, r = (5/2)/5 = ½

n = 9

Using the formula for nth term of a geometric progression,

[tex] t_{n} = a {r}^{n - 1} [/tex]

T9 = 5(½)^(9-1)

= 5/256

Answer: x = 16, y = 9

D. x + y = 25

x - y = 7

Step-by-step explanation:

        Let x be a number and y be another. First, I will write the problem out using equations. Then I can solve by graphing, see attached. Their point of intersection is the answer, x = 16 and y = 9.

    The sum of two numbers is 25

x + y = 25

    Their difference is 7

x - y = 7

          D. x + y = 25

          x - y = 7

Answer:

Any value less than 16 or greater than 24 is an outlier. :)
