Answer:

The answer that is responded to this one is what you should get

Step-by-step explanation:

Answer: 6.25.

Step-by-step explanation:

Let's put your question into a proper proportional form, because it is a ratio that is equal.

[tex]\frac{5}{12} = \frac{x}{15}[/tex]

To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.

[tex]5 * 15 / 12 = 6.25[/tex]

The answer you should get by doing this is 6.25.

Answer:

x=6.25

Step-by-step explanation:

Cross multiply

5/12=x/15

12*x=15*5

12x=75

Divide both sides by 12 to isolate the variable x

x=6.25

Or, multiply both sides by 15 to "reverse" the division being done to x

5/12=x/15

15*5/12=x/15*15

6.25=x

Answer: -118

Step-by-step explanation:

first multiply by 40. 37x 40 is 1480. No subtract 64 from both sides (1416). Multiply both sides by negative one to make the parentheses positive. -(1416)

on the inside that would be 12y so divide -1416 by 12 which is -118

I hope that's right!! :)

NOTE it isn't -118 sorry!!! I didn't see that in the original post

Answer B is correct.

Answer:

The answer is 0

Step-by-step explanation: The question can be rewritten to 19-19 so the answer would be 0

Answer:

the value of x is 0.

Step-by-step explanation:

Option A, F(x) = x, is the correct linear parent function because it represents a straight line with a slope of 1 that passes through the origin.

The linear parent function is the simplest form of a linear equation, which is described by a straight line with a slope of 1 and goes through the origin (0,0) on a coordinate plane. Among the options given, the correct answer is A. F(x) = x. This function represents a straight line that has a slope (gradient) of 1 and passes through the origin, making it the parent function for all linear equations. Options B, C, and D are not linear parent functions; B represents a linear function with a y-intercept of 1, C is a reciprocal function, and D is a quadratic function.

Answer:

I THINK:

There will be 8 grams left after 36 minutes.

Step-by-step explanation:

A half-life is how long it takes for half of the amount to go away. in this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.

36mins/16mins = 2 half lives.

now we can raise 1/2 to the power of how many half lives we have (2). then we multiply that by the amount in the sample.

(1/2)^2 * 36

1/4 * 36

8 grams

Step-by-step explanation:

If the initial number is n, one less than n is n - 1, and one more than n is n + 1. so we have:

[tex]n - 1 + n + n + 1=3n[/tex]

At first I thought this answer was too easy, so I tried for n is 6.

Answer:

a) Overall average = 76%

b) Average of first and sixth marks = 75%

Step-by-step explanation:

Let's call the marks a, b, c, d, e and f, in this order.

Then, we can write the following equations:

(a+b)/2 = 0.72 -> a + b = 1.44 (eq1)

(b+c)/2 = 0.75 -> b + c = 1.5 (eq2)

(c+d)/2 = 0.77 -> c + d = 1.54 (eq3)

(d+e)/2 = 0.78 -> d + e = 1.56 (eq4)

(e+f)/2 = 0.79 -> e+ f = 1.58 (eq5)

If we sum all equations, we have:

a + 2b + 2c + 2d + 2e = f = 7.62 (eq6)

Then, we make (eq6) - (eq2) - (eq4):

a + b + c + d + e + f = 4.56 (eq7)

a) The find the overall average, we just need to divide (eq7) by 6:

Overall average = (a + b + c + d + e + f)/6 = 0.76 = 76%

b) First we need to make (eq7) - (eq2) - (eq4):

a + f = 1.5

Then, the average is:

Average = (a+f)/2 = 0.75 = 75%

Final answer:

The overall average of the six marks is 63.5%, and the average of the first and sixth marks is 75.5%. The calculation involves setting up algebraic equations from the given average pairs and solving for the totals and individual marks.

Explanation:

To calculate the overall average and the average of the first and sixth marks, we need to use some algebra. Since we know the average of the first two, second two, and so on, we can set up equations to find the individual scores.

Let the individual marks be represented as A, B, C, D, E, and F. From the given information, we can say:

(A + B) / 2 = 72

(B + C) / 2 = 75

(C + D) / 2 = 77

(D + E) / 2 = 78

(E + F) / 2 = 79

To find the overall average, sum all equations:

A + B = 144

B + C = 150

C + D = 154

D + E = 156

E + F = 158

Adding all these together, we get 2(A + B + C + D + E + F) = 762. Then, the total sum of the six marks A + B + C + D + E + F = 381. The overall average is 381 divided by 6, which equals 63.5%

To find the average of the first and sixth marks, we can use the first and last equations we have set up:

A + B = 144

E + F = 158

Now we add the two to get A + B + E + F = 302. However, we need only the sum of A and F. Since A + B + C + D + E + F = 381, we can subtract the sum of B, C, D, and E, which we find from the other equations:

Subtract (B + C + D + E) from 381 (Total sum), we get:
381 - (150 + 154 + 156)/2 = 381 - 230 = 151

This leaves A + F = 151. Dividing by 2, we get that the average of the first and sixth marks is 75.5%

Answer:

yes you are correct 50 is 5 times as many as 10 because 10 times 5 is 50 thank me later

Step-by-step explanation:

The statement is indeed correct: 50 is 5 times as many as 10. This understanding comes from the powers-of-ten notation system. We can also relate this to the concept of order of magnitude; the order of magnitude of 50 is 10², providing an approximation of its size in powers of ten.

The question is asking if the number 50 is 5 times as many as 10. In mathematics, if you multiply 10 by 5, you do get 50, so the statement is indeed correct. This concept is part of multiplication and understood by using the powers-of-ten notation system, which is based on increases of ten.

The powers-of-ten notation system is the basis of our counting system, where each digit's place is ten times greater than the digit to its right. This notation system is used because humans have ten fingers and started counting with them.

An interesting approach is to relate this to order of magnitude. The order of magnitude of 50 is 10² because it's closer to 10² (100) than 10³ (1000). The order of magnitude only changes when you pass the square root of 10 (~3.16). Since 5 is greater than 3.16, when you multiply it by 10, it surpasses 10² (100), giving the order of magnitude as 10³. This is slightly off from the actual value of 50, illustrating how order of magnitude provides an approximation, not an exact value.

Answer:

676000

Step-by-step explanation

3 digits of the 5-digit code are number 0-9 which is 10 numbers that could go into that spot, after the three digits there are two letters and because there are 26 letters in the alphabet you would multiply 10*10*10*26*26 which equals 676000

There are 676,000 possible codes.

An arrangement of objects where the order in which the objects are selected does not matter.

Given that  library labels each book with a five-digit code to identify the books in their computer system.

Each code is 3 digits (0-9) followed by two letters

We need to find the possible number of codes.

There are 10 possible digits (0-9) for each of the first three positions, and 26 possible letters (A-Z) for each of the last two positions. Therefore, the total number of possible codes is:

10 x 10 x 10 x 26 x 26 = 676,000

Hence, there are 676,000 possible codes.

Answer:

32.59

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term and r the common ratio )

4[tex](\frac{8}{9}) ^{n-1}[/tex] ← is the n th term expression

with a = 4 and r = [tex]\frac{8}{9}[/tex]

The sum of n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(1-r^n)}{1-r}[/tex], thus

[tex]S_{20}[/tex] = [tex]\frac{4((1-\frac{8}{9}) ^{20}) }{1-\frac{8}{9} }[/tex]

      = [tex]\frac{4(1-\frac{8^{20} }{9^{20} } )}{\frac{1}{9} }[/tex]

      = 36( 1 - 0.0948)

      = 36(0.905)

      = 32.59 ( to the nearest hundredth )

Answer:

2 6 10 14

Explanation:

Nth term works by having n as the term's place in the sequence.

So the first term , n=1 and you work it out from there

Second term, n=2 and you work it out from there

And so on

So:

4×1 = 4 - 2 = 2

4×2 = 8 - 2 = 6

4×3 = 12 - 2 = 10

4×4 = 16 - 2 = 14

Final answer:

The reflection of point (4, -2) across the y-axis is (-4, -2), and the reflection of point (7, -4) across the x-axis is (7, 4).

Explanation:

When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same. Therefore, the reflection of the point (4, -2) across the y-axis is (-4, -2).

Similarly, when a point is reflected across the x-axis, the y-coordinate changes sign while the x-coordinate remains unchanged. This means the reflection of the point (7, -4) across the x-axis is (7, 4).
