What’s the greatest common factor for 30,48,60

To obtain 200 mL of a 4.5% acid solution, Mr. Larson needs 120 mL of the 3.5% acid solution and 80 mL of the 6% acid solution.

To find the volumes of each of the two solutions needed, we can set up a system of equations based on the principle of concentration:

Let x be the volume of the 3.5% acid solution needed, and y be the volume of the 6% acid solution needed.

The equation for the total volume is x + y = 200 mL.

The equation for the concentration is (0.035x + 0.06y) / 200 = 0.045.

Solving the system of equations, we can find the values of x and y.

x = 200 - y

(0.035(200 - y) + 0.06y) / 200 = 0.045

Simplifying the equation, we get:

7 - 0.035y + 0.06y = 9

0.025y = 2

y = 80 mL

Substituting the value of y into the equation x = 200 - y, we get:

x = 200 - 80

x = 120 mL

Therefore, Mr. Larson needs 120 mL of the 3.5% acid solution and 80 mL of the 6% acid solution to obtain 200 mL of a 4.5% acid solution.

Answer:

he said its d he's right

Step-by-step explanation:

The additive inverse, or opposite, of a number is the value you add to it to get zero. You find it by changing the sign of the number. So the additive inverse of 5 is -5, and the additive inverse of -3 is 3.

In mathematics, the additive inverse of a number is what you add to a given number to get zero. This is often known as the 'opposite' or 'negation' of a number. The additive inverse of a number 'a' is denoted as '-a'.

For example, the additive inverse of 5 is -5, because 5 + (-5) = 0. Similarly, the additive inverse of -3 is 3, because -3 + 3 = 0.

To find the additive inverse of a number, you essentially change the sign of the number. If the number is positive, its additive inverse will be negative. If the number is negative, its additive inverse will be positive.

Dingane has approximately 0.432 or about 0.432 555-cent coins.

To find out how many 555-cent coins Dingane has, we need to determine 30% of $8.00.

We can do this by multiplying $8.00 by 30% or 0.30.

30% of $8.00 is calculated as:

So, Dingane has $2.40 worth of 555-cent coins.

To determine how many 555-cent coins this is, we need to divide $2.40 by the value of each coin.

Note that 555 cents is equal to $5.55.

So, we can divide $2.40 by $5.55 to find the number of 555-cent coins.

The number of 555-cent coins Dingane has is calculated as:

Therefore, Dingane has approximately 0.432 or about 0.432 555-cent coins. Since coins cannot be divided, we can round this down to 0.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Jana and her sister went to a restaurant for dinner. Jana's dinner cost $5 more than her sisters. if their combined bill was $19 without a tip.

Jana's cost will be calculated by forming two linear expressions as below:-

J + S = 19

J - S = 5

Solve the above equation by elimination method.

2J = 19 + 5

2 J = 24

J = 24 / 2 = 12

Therefore, the price of Jana's dinner will be $12.

Multiplying 6 and 8 gives the value of 48. The question seems to mention '5s fact', which typically refers to multiplication facts of 5, but this does not directly relate to multiplying 6 and 8.

It seems that the '5s fact' mentioned in the question doesn't directly apply to the multiplication problem provided (6x8). Rather, in the context of simple multiplication, a 'fact' typically refers to a multiplication fact, which is a statement of an equation that can be considered universally true in arithmetic. For instance, 5x1=5 or 3x2=6 are multiplication facts.

To multiply 6 and 8, regardless of any number's multiplication facts, you would simply calculate 6x8, which equals 48.

With regard to the '5s fact', if we are referring to the multiplication facts of 5, these would include equations like 5x1=5, 5x2=10, and so on. However, none of the '5s facts' directly relate to multiplying 6x8. If the question refers to some other concept that has not been clarified, please provide further details.

Answer:

Step-by-step explanation:

39.538 divided by 5.3 using standard method. Which is true

Answer:

It is increased by 100%. The numerator is two times more than the denominator. That's why original fraction will become [tex]\frac{2x}{y}[/tex].        

Step-by-step explanation:

We need to find the percentage, if its numerator is increases by 60% and its denominator decreases by 20%.

First, we let the original fraction: [tex]\frac{x}{y}[/tex]

We have given its numerator is increases by 60% and denominator is decreases by 20% then,

New fraction will become = [tex]\frac{1.6x}{0.8y}[/tex].

Divide the new fraction by original fraction, then we get:

[tex]\frac{1.6x}{0.8y}[/tex]/ [tex]\frac{x}{y}[/tex]

[tex]\frac{1.6x}{0.8y}[/tex]* [tex]\frac{x}{y}[/tex]

Then, it will become [tex]\frac{1.6}{0.8}[/tex].

We can see that, The numerator is two times more than the denominator. That's why original fraction will become [tex]\frac{2x}{y}[/tex].

It is increased by 100%.

If we take an example, Suppose the original fraction is [tex]\frac{5}{8}[/tex] and the new fraction will become [tex]\frac{1.6*5}{0.8*8}[/tex].

= [tex]\frac{8}{6.4}[/tex] = [tex]\frac{80}{64}[/tex]

= [tex]\frac{10}{8}[/tex], it is twice of original fraction [tex]\frac{5}{8}[/tex].

At 2 pm, the angle between the hour hand and the minute hand of a clock is 20 degrees. The calculation takes into consideration that the hour hand advances as minutes pass within an hour.

The angle between the hour and the minute hand at 2 pm can be calculated in the following way. First, remember that a full circle, representing one hour on a clock, equals 360 degrees. So, each hour equals 30 degrees (360 divided by 12 hours). However, the hour hand also moves as the minutes pass. At 2 pm exactly, the minute hand is on 12, while the hour hand is at 2. But, the hour hand has also moved 1/3 of the way between 2 and 3 (since 20 minutes have passed in the hour). It is closer to 3 by 1/3 of 30 degrees which equals 10 degrees. Hence, the hour hand is at a position of 60 degrees (2 hours times 30 degrees per hour). Therefore, the angle between the two hands at 2 pm is 20 degrees.
