i need help with finding the value of x

Answer:

Step-by-step explanation:

Step one:

given

number of blinks= 3

time taken to blink=15 seconds

the rate of blink is given as

rate= number of blinks/time taken

rate= 3/15

rate= 1/5 blinks per second, 0.2 blinks per second

Step two:

hence for a 65 second period, the number of blinks is

rate=number of blink/time

0.2=number of blink/9=65

cross multiply we have

number of blink=0.2*65

number of blink=13 blinks

I can't read the fraction for B

but 2 3/4 is bigger than 2 1/2

Answer:   36

Step-by-step explanation:

Answer:

x + y + z = 123

Step-by-step explanation:

x:y:z = 7:2:5

Let x = 7a, y = 2a, z = 5a

Since x - z = 18

Therefore,

7a - 5a = 18

2a + 18

a = 18/2

a = 9

7a = 7*9 = 63

2a = 2*9= 15

5a = 5*9 = 45

x + y + z = 63 + 15 + 45

x + y + z = 123

Answer:

M + F = total

6F + F = total

7F = total

F = (1/7) total

Explanation:

You can look at this as a ratio also.

The ratio of females to males is 1:6

That means out of every 7 students,

1 is female and 6 are male.  

1 out of 7 is 1/7

Answer:

D The volume of a cube increases by a factor of 8 when its edge length doubles

Step-by-step explanation:

Volume of a cube is represented by the function

[tex]V(x)=x^3[/tex]

where [tex]x[/tex] represents the edge length of the cube

Now when [tex]x=2x[/tex] i.e., when the edge length is doubled we have

[tex]V(2x)=(2x)^3\\\Rightarrow V(2x)=8x^3\\\Rightarrow V(2x)=8(V(x))[/tex]

It can be seen that the volume of the cube increased by 8 times when edge length doubles.

Answer:

$2.58

Step-by-step explanation:

First, we should divide each number by 10 to get the amount per person we get...

10 cups

10 plates

20 balloons

Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...

1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545

2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475

3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56

Now, we add them all up to get $2.58

Hope this Helps!!! :)

Step-by-step explanation:

Step-by-step explanation:

1 can of corn = c

1 can of green beans = b

Marissa-> 4c+8b=7

Bob-> 8c+7b=8.60

form a simultaneous equation:

4c+8b=7

8c+7b=8.60

find a common coefficient, e.g. make the number of cans of corn that Marissa has, equal to the number of cans of corn that Bob has, so you would multiply the top equation by 2, so both people have 8 cans of corn

8c+16b=14

8c+7b=8.60

now you can cancel out the cans of corn, and subtract the second equation from the first one, so you would get:

16b-7b=9b

14-8.60= 5.4

so, 9b=5.4, and b= 0.6

so 1 can of green beans would cost $0.60

Step-by-step explanation:

Third table  represents the second piece of the function f(x)

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given function is given by -3.5x+0.5, x<1 and 8-2x≥1

The second piece of the function f(x) is 8-2x ,x≥1

Now, we substitute some values of x and find the corresponding function values and check which table satisfy the points.

For x = 1

f(1)=8-2(1)=6

f(1)=6

For x = 2

f(2)=8-2(2)=4

f(2)=4

For x = 3

f(3)=8-2(3)=2

f(3)=2

Among the given tables, third tables contains these values.

Hence, Third table  represents the second piece of the function f(x)

Answer: 1/26

Step-by-step explanation:

Out of the 52 card deck there is a single Jack of diamonds and a single ace of clubs. Their individual probabilities are therefore both 1/52.

For the probability that you can pick either of those card you have to add up their probabilities;

= 1/52 + 1/52

= 2/52

The general formula for nth term of given sequence is:

[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

Step-by-step explanation:

Given sequence is:

54,18,6.....

In order to write the general formula of a sequence, first of all the common ratio has to be found. Common ratio is the ratio between consecutive terms of a geometric sequence.

[tex]Here\\a_1 = 54\\a_2 = 18\\a_3 = 6\\And\\r = \frac{a_2}{a_1} = \frac{18}{54} = \frac{1}{3} \\r = \frac{a_3}{a_2} = \frac{6}{18} = \frac{1}{3}[/tex]

The general formula is:

[tex]G_n = A_1 (r)^{n-1}[/tex]

Putting the values of a1 and r

[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

Hence,

The general formula for nth term of given sequence is:

[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

Answer:

Step-by-step explanation:

If he scored 71 and 65 and needs an average above 77, you took the average needed of 77 and times by 3 since you will have 3 test total. 3*77=231. Take the 231- what you already have which is 136, to get 95. He will need a score of at least 95 to average the 77. 71+65+95=231 231/3= 77

So, x≥95. X is the next test. It would need to be greater than or equal to 95.

Answer:

its C got it on E2020

Step-by-step explanation:

A line does not extend from a side of a triangle to form angle 2. Then the correct option is C.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The exterior angle of a triangle is almost always equal to the addition of the interior and opposing interior angles. The term "external angle property" refers to this feature.

Choose the triangle in which angle 2 is not an exterior angle.

The external angle can be made when the line is extended and the angle is formed outside the triangle, which is known as the exterior angle.

A line does not extend from a side of a triangle to form angle 2. Then the correct option is C.
