Answer:
94 boys and 56 girls.
Step-by-step explanation:
150/8 = 18.75 = x
b=x*5 = 94
g=x*3 = 56
b+g=150
Looking at the question, we see that the ratio of boys to girls is 5:3, the total is 8. We are trying to find what the ratio of boys to girls is while the total is 150. Now, we can easily divide 150 by 8, finding one part of our answer! 150 ÷ 8 ≈ 18 [tex]\frac{3}{4}[/tex]. now to multiply that by the amount of boys and girls (5:3), 18 [tex]\frac{3}{4}[/tex] × 5 = 93 [tex]\frac{3}{4}[/tex] and 18 [tex]\frac{3}{4}[/tex] × 3 = 56 [tex]\frac{1}{4}[/tex]. After we round we get 94:56.

Determine whether the first system of equations is equivalent to the second system of equations. Explain.
3x + 5y = 1
18x + 30y = 6
2x-6y=38 10x - 30y = 190
Answer:
1 Answer: Since these two lines are the same line, they have infinite solutions Answer: So first thing you gotta do is multiply the first equation by 5. Your first equation will be. Since these two lines are the same line, they have infinite solutions.
Another Answer: You would have to multiply either equation in order to get one of the variables to cancel.
I would multiply the first equation by -5.
-5(3x + 6y = -2)
-15x -30y = 10
15x + 30y = -10
0 + 0 = 0
Since everything cancels and the equation is true, the solution is Infinitely many solutions, or all real numbers.

Let f(x)=3(12)2x. Which is equal to f(2)?
Answer:
f(2) = 144
Step-by-step explanation:
Unless there is something I don't see (quite possible), the question is 3*12*2
multiplied by x
3*12 * 2 = 72 so the question simplifies to f(x) = 72x
f(2) = 72(2)

jacob said the product of 8/9 and 2 and 3/4 is 3 and 1/4. how can you tell that his answer is wrong?
Answer:
he is wrong becuase 89 times a number greater than 0 cannot result in a product greater than the number
Step-by-step explanation:
Based on real algebra properties, we know that the product of 8/9 and 2 and 3/4 is not 3 and 1/4.
How to infer the correctness of a product?The multiplication of two positive integers equals another positive integer. Each term of a multiplication can be rewritten as sums of multiples of 10, which can be simplified by algebra:
Given; Definition of multiplication
8/9 and 2 = 26/9
3/4
The product is;
26/9 x 3/4
= 13 x 1/6
= 13/6
Based on real algebra properties, we know that the product of 8/9 and 2 and 3/4 is not 3 and 1/4.

What is a set of data?the dataset is a collection of numbers connected by theme. There are three ways to work with datasets: mean, median, and mode. The mean is the average of the dataset, the median is the median of the dataset, and the mode is the number or value that occurs most often in the dataset.
Standard deviation of a data set is the square root of the calculated variance of a set of data. The formula for variance (s2) is the sum of the squared differences between each data point and the mean, divided by the number of data points.

Answer:
1,304,0006Step-by-step explanation:
You may recall that when you learned multiplication of decimals, there were two facts involved:
the total number of decimal digits when two decimal numbers are multiplied is the sum of the numbers of decimal digits in each onemultiplying by 10 adds a zero on the right. (Multiplying by 10^n adds n zeros on the right.)__
Here, we combine these facts.
Multiplying the decimal number 1.304 by 1000000 will add 6 zeros to the right of 1304 to make it 1304000000. Placing the decimal point in this product so there are 3 decimal digits (as there are in 1.304) makes this number be ...
1,304,000.000 . . . . . . product of 1.304 and 1,000,000
You will notice the decimal point in 1.304 has effectively moved 6 places to the right.
