a is 25% of b
b is 30% of c.
Write the ratio a:b:c
Give your ratio in its simplest form.

Answer:

15

Step-by-step explanation:

8² + 15² = c²

To find : Value of c

8² = 8 x 8 = 64

15² = 15 x 15 = 225

c² = 225

225 = 15 x 15 = 15²

So,

c² = 15²

c = 15

The new statement becomes "If the dog jumps in the lake, then it can't come in the house".

Legal syllogism is a legitimate concept that deals with the law and how it is applied, specifically a type of argument that uses deductive reasoning to determine whether a given act is legal.

We have a statement:

R → S: If the dog jumps in the lake, then it gets wet.

S > T: If the dog gets wet, then it can’t come in the house.

After applying the law of syllogism to form a new statement:

R→T:

If the dog jumps in the lake, then it can't come in the house.

Thus, the new statement becomes "If the dog jumps in the lake, then it can't come in the house".

Step-by-step explanation:

Answer + Step-by-step explanation:

y = 2x + 1 represents a linear function then the its graph is a line

To draw the line we have to determine two points that lie on that line

If x = 0 → y = 2(0) + 1 = 1 then the point A(0,1) lies on the line

If x = 2 → y = 2(2) + 1 = 5 then the point B(2,5) lies on the line

Now all we have to do is joining the points A and B with a line

The line AB represents our graph

Answer:

Step-by-step explanation:

in 6 years we know that it will be half,  because that's what "half life" means

in 3 years it's only  loses  1/2 * 1/2 = 1/4 of it's mass

in 1 year it's only loses 1/6 * 1/2 = 1/12 of it's mass

from that we can make the formula that

current weight of radium  = Wr

Mass of radium orginal = Mo

year of time = t   ( must be in years, not days, months or weeks )

Wr = (1/12)*t* Mo

Answer:

Problem 21:

Slope = -3
y-intercept = (0, 7)

Problem 23:

Slope = 1
y-intercept = (0, -2)

Problem 22:

Slope = [tex]\frac{2}{3}[/tex]
y-intercept = (0, 1)

Step-by-step explanation:

In the slope formula, the coefficient of x (the number times x) is the slope. The number added or subtracted from it is the y-intercept.

In problem 21, -3 is the coefficient of x, so thats the slope. 7 is what's being added, so that is the y-intercept.

In problem 23, 1 is the coefficient of x (a singular x is the same as 1, or -1 if the variable is negative), so thats the slope. -2 is what's being subtracted, so that is the y-intercept.

In problem 22, [tex]\frac{2}{3}[/tex] is the coefficient of x, so thats the slope. 1 is what's being added, so that is the y-intercept.

Answer:

A. is the correct answer tnx to the points

The function f(x) = 1/[(x-1)(x+4)] is a rational function with two vertical asymptotes and one horizontal asymptote, which is graphed below.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The function f(x) = 1/[(x-1)(x+4)] is a rational function with two vertical asymptotes and one horizontal asymptote.

The vertical asymptotes occur when the denominator, (x-1)(x+4), is equal to zero. This happens when x = 1 or x = -4.

Therefore, the graph will have two vertical asymptotes at x = 1 and x = -4.

The horizontal asymptote can be found by looking at the behavior of the function as x approaches positive or negative infinity. As x gets very large in either direction, the terms (x-1) and (x+4) become insignificant compared to x².

Hence, the correct option is (B) f(x) = 1/[(x-1)(x+4)].

Answer:

Step-by-step explanation:

4. Nicole can make 7 quarts of lemonade with 10 cups of sugar.

If 3/4 cup of sugar is used to make 1 quart of lemonade and 10 cups of sugar are available, then you multiply 3 times 10 (when multiplying fractions, you only multiply with the numerator, not the denominator) which will give you 30.

Now, you can write it as 30/4. Using simple division, you find that 30/4 is 7.5 (or 7 and 1/2), and because we're trying to find how many full quarts we can make using 10 cups of sugar, your answer will be 7.

5. Each person will get 0.83 repeating (or 5/6) boxes of raisins.

In this problem, we have 6 people and we have to share 5 boxes of raisins among all of them. We know that each person can't get 1 because there would have to be 6 boxes (1 for each person), so we have a fraction (or decimal, depending on where you're at).

Dividing 5/6, you'll simply get 5/6 because you can't simply this any further, but if you were to write this as a fraction, you'd get 0.83 repeating (over the 3).

6. Each class will receive 30 boxes of cracker jacks.

We know that there are 153 boxes of cracker jacks available, and this needs to then be split among 5 different classes. So, to find the answer, we have to divide 153 by 5. In doing that, we get 30.6, but because we're trying to find the whole number that the classes will receive, as you can't get a fraction of a box (at least, I assume), then each class will get 30 with 3 boxes remaining.

If the first term is 25 and the common difference is 4. Then the 97th term of the sequence will be 409.

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The sequence is given below.

25, 29, 33, ...., so on

Then the first term is 25. And the common difference is 4.

Then the 97th term will be given as

[tex]\rm a_n = a + (n - 1)d[/tex]

where

n = 97

a = 25

d = 4

Then we have

a₉₇ = 25 + (97 - 1)4

a₉₇ = 25 + 96 x 4

a₉₇ = 25 + 384

a₉₇ = 409

Then the 97th term of the sequence will be 409.

Answer:

A solar panel is the best way to transform electrical energy into other forms of energy

Answer:

original number:  27

reversed number:  72

Step-by-step explanation:

Let the tens place digit = a

Let the units place digit = b

⇒ Original two-digit number = 10a + b

⇒ Reversed two-digit number = 10b + a

If the reversed two-digit number is 9 less than 3 times the original number:

⇒ 10b + a = 3(10a + b) - 9

⇒ 10b + a = 30a + 3b - 9

⇒ 7b = 29a - 9

If the different of the two numbers is 45 (and the reversed number is larger than the original number):

⇒ (10b + a) - (10a + b) = 45

⇒ 10b + a - 10a - b = 45

⇒ 9b -9a= 45

⇒ 9(b - a)= 45

⇒ b - a= 5

⇒ b = 5 + a

Substitute  b = 5 + a  into  7b = 29a - 9  and solve for a:

⇒ 7(5 + a) = 29a - 9

⇒ 35 + 7a = 29a - 9

⇒ 44 = 22a

⇒ a = 2

Finally, substitute the found value of a into  b = 5 + a  and solve for b:

⇒ b = 5 + 2 = 7

Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 hours.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we have that the mean and the standard deviation are given, respectively, by:

[tex]\mu = 400, \sigma = 30[/tex].

The proportion of the batteries will last more than 420 hours is one subtracted by the p-value of Z when X = 420, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{420 - 400}{30}[/tex]

Z = 0.67

Z = 0.67 has a p-value of 0.7486.

1 - 0.7486 = 0.2514.

0.2514 = 25.14% of the batteries will last more than 420 hours.

$16000 for five years at 5% APR compounded semiannually gives an interest of 4481 dollars.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest compounded semiannually is,

A = P[1 + (r/2)/100]²ⁿ.

Where, A = amount, P = principle, r = rate and n = time in years.

Given,  $16,000 is deposited for five years at 5 % compounded semiannually.

A = 16000[1 + (5/2)/100]²ˣ⁵.

A = 16000[1 + 0.025]¹⁰.

A = 16000[1.025]¹⁰.

A = 16000×1.28.

A = 20481.

So, the interest earned is (20481 - 16000) = 4481 dollars.
