20% of the girls in class have blonde hair. 16 girls do not have blonde hair. How many total students

Answers

Answer 1
The problem is to find how many students have either blond hair or glasses and then divide that by the total number of students; that will find the probability.
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?
2m-3 =2+1m

Answers

Answer:

m=5

Step-by-step explanation:

There are no fractions involved to eliminate.

2m-3=2+1m

m=5

Based on the given scenario, the solution to the equation 2m - 3 = 2 + 1m is m = 5.

What is fraction?

Fractions are a way of representing parts of a whole. They are written in the form of a numerator and a denominator, separated by a horizontal line.

For example, the fraction 3/4 represents three parts of a whole that is divided into four equal parts.

To eliminate the fractions in the equation 2m - 3 = 2 + 1m, we can multiply both sides of the equation by the least common multiple (LCM) of the denominators of the fractions.

However, in this equation, there are no fractions, so we don't need to multiply by anything to eliminate them. The equation is already in a form that can be solved using basic algebraic techniques.

To solve for m, we can start by moving all the m terms to one side of the equation and all the constant terms to the other side:

2m - 1m = 2 + 3

Simplifying, we get:

m = 5

Therefore, the solution to the equation 2m - 3 = 2 + 1m is m = 5.

In an inverse variation, X = -8 when
y= - 1/4. What is the value of y when x = 4?

Answers

Step-by-step explanation:

xy = k, where k is a real constant.

When y = -1/4, x = -8.

=> k = (-8)(-1/4) = 2.

Therefore when x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5

What is the value of y ?

In an inverse variation, X = -8 wheny= - 1/4.

y= - 1/4.

the value of y when x = 4

In the equation xy = k, k is a real constant.

X equals -8 at y = 1/4.

=> k = (-8)(-1/4) = 2.

Consequently, if x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5.

Solving an Inverse Variation Problem:

The variation formula is either y = k/x or k = xy.Replace with the supplied values to determine the value of k.With the known value for k, rewrite the variation equation as y = k/x.Find the unidentified by substituting the remaining values.

Find the number whose 23.2% is 34.8.​

Answers

Answer:

The required number will be:

x = 150

Step-by-step explanation:

Let 'x' be the number

so

23.2% of x = 34.8

23.2% × x = 34.8

23.2/100 × x = 34.8

0.232x = 34.8

divide both sides by 0.232

0.232x/0.232 = 34.8/0.232

x = 150

Therefore, the required number will be:

x = 150

Let:

Mr. Marcos bought chicken and beef from the butcher and fish from the fish market for a barbecue. Thee ratio of the weight of chicken to the weight of the beef to the weight of the fish he bought was 3 : 1 : 5. He bought 10 pounds of fish. What was the total weight of meat he bought from the butcher?

Answers

Answer:

8 pounds

Step-by-step explanation:

Total ratio = 3 + 1 + 5 = 9

x = total pounds of chicken, beef and fish bought

equation for pounds of fish bought = 5/9 × x = 10

divide both sides by 9/5

x = 18

pounds of chicken bought = 3/9 x 18 = 6 pounds

pounds of beef bought = 1/9 x 18 = 2 pounds

total weight of meat bought = 6 + 2 = 8 pounds
