“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.

Answers

Answer 1

Step-by-step explanation:

613 and 623 are very close values.

multiplying by 12 or a division by 2 changes the starting value drastically.

so, this cannot be right.

and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.

so, therefore, even without actually calculating the numbers, the statement is proven false.

At a pet store the ratio of cats to dogs sold was 6 : 5. If there were 12 cats that were sold, how many dogs were sold?

Answers

Ratio of cats to dogs is 6:5.

Which means for every 6 cats sold 5 dogs are sold.

Is 12 cats are sold: 6*2=12
Because we multiply the number of cats sold by 2 we do the same for dogs:
5*2=10.

So, if 12 cats are sold then 10 dogs are sold.
The answer is 10.

Maggie makes some fruit punch. She mixes 2 1/2 quarts of grape juice with 1 1/2 quarts of orange juice. One quart of grape juice costs $1 less than one quart of orange juice. She finds that the total of making the fruit punch is $12.50. Calculate the cost of each quart of grape juice and each quart of orange juice.

Answers

Grape juice(G) is 1$ less than Orange juice (O)
G = O - 1

Orange juice and Grape juice is 12.50 total.
O+G=12.50
or
O+O-1=12.50 since G=O-1

Solve
2O-1=12.50
2O=13.50
o=6.75

The cost is 6.75$ per quart of orange juice

Grape is just 1$ less than that. So 6.75-1 = 5.75. Grape juice costs 5.75 per quart.

We have 2 and 1/2 quarts of grape juice and 1 and 1/2 quarts of orange juice. Or 5/2 and 3/2 to make it easier.

Multiply the amount of quarts with the costs per quart.
5/2*5.75= 14.375

3/2*6.75=10.125

Total costs is
14.375+10.125=$24.5

The answer is it costs about $10.13 for orange and $14.38 for grape.

A line is a one-dimensional shape that is straight. The equation of the given line in slope-intercept form can be written as y=(5/6)x -2.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The given line goes through two points, (0, -2) and (6, 3). Therefore, the slope of the given line can be calculated as,

Slope, m = (-2 - 3)/(0 - 6) = -5 / -6 = 5/6

Further, it can be seen that the line intersects the y-axis of the graph at (0, -2), therefore, the y-intercept of the given line is -2.

Since the equation of a line in slope intercept form is written as y=mx+c. Therefore, substituting the slope and the y-intercept in the equation.

y=mx+c

y=(5/6)x -2

Thus, the equation of the given line in slope-intercept form can be written as y=(5/6)x -2.

it took jose two-thrids of an hour to complete his math homework on monday,three- fourths of an hour on tuewsday , and two- fifths of an hour on wednesday. how many hours did it take jose to complete his homework altogether

Answers

It took Jose an hour and 49 minutes to complete his homework! (109 minutes)

On Monday, Jose took 2/3 of an hour to complete his math homework. We know that is hour is 60 minutes. Divide 60 by 3 (the denominator) and you get 20. Multiply 20 x 2 (numerator) and you get 40 minutes! 2/3 of an hour is 40 minutes.

On Tuesday, Jose took 3/4 of an hour to complete his homework. Divide 60 by 4 (denominator), and you get 15! Multiply 15 x 3 (numerator) and you get 45. 3/4 of an hour is 45 minutes.

On Wednesday, Jose took 2/5 of an hour to complete his homework. Divide 60 by 5 (denominator), and you get 12. Multiply 12 x 2 (numerator) and you get 24! 2/5 of an hour is 24 minutes.

Finally, you add the three sums of minutes from each day. 40 + 45 + 24 = 109.

Subtract 60 from 109 (109 - 60) and you get a remainder of 49 minutes. This means that it took Jose and hour and 49 minutes to finish his homework.

The slope of that line is -1, so m = -1.

The point you were told to use is (-2,2), so point-slope form starts as:

2064 g = 2064 g

16.7 kg * 1000 g / kg = 16,700 g

If a²+b²=8ab, determine (a+b) in terms of a and b​

Answers

[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]

Answer:

[tex]\mathsf{\sqrt{10ab} }[/tex]

Step-by-step explanation:

We have the rules of indices, one of which is:

[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]

Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.

In the question, we're provided with one equation, i. e.,

a² + b² = 8ab . . . . . . . . (¡)

And, were asked to find out the value of (a+b) in terms of ab.

The above rule has variables that fit in the question efficiently!

So, instead of solving for (a+b), we'll be solving for (a+b)²,  then go for (a + b):

=> (a + b)² = (a² + b²) + 2ab

from eqn. (¡):

=> (a + b)² = 8ab + 2ab

=> (a + b)² = 10ab

taking under root on both the sides:

=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]

That's the answer,  [tex]\mathsf{\sqrt{10ab} }[/tex]!
