Martin has read ​40% of a book. He has 30 more pages to finish. How many pages are there in the​ book?

Answers

Answer 1

Answer:

75

Step-by-step explanation:

Answer 2

Answer:

There are 50 pages in the book.

Step-by-step explanation:

Given that:

Martin has read 40% of the book.

Remaining percent = (100 - 40)% = 60%

Number of pages left to finish = 30

Let,

x be the total number of pages in the book.

60% of x = 30

[tex]\frac{60}{100}x=30[/tex]

0.6x = 30

Dividing both sides by 0.6

[tex]\frac{0.6x}{0.6}=\frac{30}{0.6}\\x= 50[/tex]

Hence,

There are 50 pages in the book.

How would I prove KM = HM?
Given that GJ is the perp bisector of HK

Answers

Answer: See step by step

Step-by-step explanation:

Since GJ is the perpendicular bisector of HK it bisects HK and make J the midpoint of HK. Since J  is the midpoint we can construct a congruence statement of  KJ≅JH. Then we know in the diagram Angle MJK= 90°, becuase it form a ⊥ line so it is 90° that also means MHJ forms a 90 ° angles becuase they also form a ⊥ line. So that means KJM≅HJM because of transitive property(a=b, b=c, then a=c). Both triangles also include side MJ, so using the reflexitive property( a=a),They are congruent. Since we proved they have a two congruent sides, with a included angle in between them we can use the SAS theorem (Side-Angle-Side) to prove they are congruent. So ΔKMJ≅ΔHMJ Then KM=HM by CPCTC.

What is the mean income of the following three people surveyed? Person A: S22,000, Person B: $31,000, Person :
$21,000. Round to the nearest $100

Answers

Answer:

$24,700

to get this answer you add all the numbers together so in this case 22,000 31,000 and 21,000 and you get 74,000 then you divide by how many numbers you originally had so in this case 3. so you get 24,666.666666667 and since the tens place is 5 or higher you round the hundreds up one so you get 24,700.

Here's the work

22,000+31,000+21,000=74,000

74,000÷3=24,666.666666667

which rounds to 24,700

Leslie shows a funny video to 5 of her friends. Every hour, the video

views triple. Leslie shows a funny video to 5 of her friends. Every hour, the video

views triple. How many people saw the video on the 7th hour? many total people saw the video after the 7th hour?

Answers

Answer:

10,935 views

Step-by-step explanation:

We can first design a formula for this scenario. Since the views triple this means that the initial views (i) needs to be multiplied by 3. Since this happens every hour we need to raise 3 to the power of the number of hours (h) that has passed by. This would give us the total number of views at that hour. Therefore, the formula would be the following...

i * [tex]3^{h}[/tex]

We can input the values given to us into the formula and solve it for the total number of view. The initial number of views would be 5 (one for each friend) while we are trying to find the total number of views in the 7th hour.

5 * [tex]3^{7}[/tex]

5 * 2187

10,935 views

The function below has at least one rational zero. Use this fact to find ALL zeros of the function.

g(x)=5x^3+x^2-20^x-4

If there is more than one zero, separate them with commas. Write exact values, not decimal approximations.

Answers

Answer:

x = 2, -2, -1/5

Step-by-step explanation:

g(x)= 5x^3+x^2-20x-4

g(x)= x^2(5x+1)-4(5x+1)

g(x)=(x^2-4)(5x+1)

g(x)=(x-2)(x+2)(5x+1)

x-2=0

x= 2

x+2=0

x= -2

5x+1=0

x= -1/5

What is Square root?

In mathematics, a square root of a number x is a number y such that

y² = x.

Given is number and it is asked to find its square root.

Assume the number whose square root is to be found be [x]. Then, we can calculate the square root as -

A = √x

For example -

x = 9

A = √9

A = √(3 x 3)

A = √(3)²

A = 3

Consider the sample space given below.

A die is a cube with six sides on which each side contains one to six dots. Suppose a blue die and a gray die are rolled together, and the numbers of dots that occur face up on each are recorded. The possible outcomes of the sample space S are listed as follows, where in each case the die on the left is blue and the one on the right is gray.


S= {11, 12, 13, 14, 15, 16, 21, 22, 23, 24, 25, 26, 31, 32, 33, 34, 35, 36, 41, 42, 43, 44, 45, 46, 51, 52, 53, 54, 55, 56, 61, 62, 63, 64, 65, 66}

Write the following event as a set.
The event that the numbers showing face up are the same.
E = ....................?
Compute the probability of E.

Answers

Answer:

1 / 6

Step-by-step explanation:

Probability is a measure of the likelihood of an event to occur. The probability for an event to occur is between 0 and 1.

The Probability of an event occurring is the ratio of the number of event in the sample space to the total number of possible outcomes.

The number of possible outcomes [n(S)] from rolling a blue die and a gray die is 36.

n(S) = 36

Let E be an event that the numbers showing face up are the same.

E = {11, 22, 33, 44, 55, 66}, n(E) = 6

The probability of E = P(E) = number event / number of possible outcomes =

P(E) = n(E) / n(S) = 6 / 36 = 1 / 6

I have attached an image to make the question clearer.

15c^(-8)d^(0).

Using the zero exponent property (a^0 = 1),

d^0 = 1. Therefore we have:

15c^(-8)(1) = 15c^(-8).

Using the negative exponent rule [a^(-r) = 1/(a^r)],

c^(-8) = 1/(c^8). Therefore we have:

15 x 1/(c^8) = 15/(c^8).
