Step-by-step explanation:

1.

a mother is a she, not a he ...

anyway, we need to make 2/3 and 3/4 comparable.

for this we need to bring both fractions to a common denominator, which is usually the smallest common multiple of the denominators.

yes, 12 is the smallest number that can be divided by 3 and by 4 without remainder.

to transform a fraction too another denominator, we need to multiply it by a fraction a/a, which has the value 1, of course (so we don't change the value of the original fraction), but changes the denominator to the desired number.

what do I multiply with 4 to get 12 ? 3.

so, I multiply 3/4 by 3/3 = 9/12.

what do I multiply with 3 to get 12 ? 4.

so, I multiply 2/3 by 4/4 = 8/12.

now we can compare and calculate :

out of the total of 9/12kg 8/12kg were used.

that means

1/12kg of carrots are left.

2.

this is a strange question, as watermelons, bananas and melons are very differently sized. so, for example 1/2 watermelon and 1/2 banana are very different quantities.

so, what does e.g. 1 fruit mean ?

or if we understand the fractions as shares of the overall smoothie, then we have too much. 4/6 (watermelon) + 2/6 (melon) = 6/6 = 1 (whole smoothie).

so, what to do with the banana ?

this question does not make any sense at all.

but if it is just to add fractions, we can do that :

4/6 + 1/2 + 2/6

as mentioned above, 4/6 + 2/6 = 6/6 = 1

1 + 1/2 = 2/2 + 1/2 = 3/2 = 1.5 or 1 1/2

so there is 1 1/2 fruit in the smoothie (whatever that means).

3.

1 1/2 + 2 1/2 = 2/2 + 1/2 + 4/2 + 1/2 = 8/2 = 4

in total, there are 4 cups of sugar needed.

Answer:

32 : 12 is the second equivalent ratio. = 48 : 18 is the third equivalent ratio. Therefore, the three equivalent ratios of 8 : 3 are 16 : 6, 32 : 12 and 48 : 18

Answer:

x = √55

Step-by-step explanation:

using Pythagoras Theorem:

x² + 3² = 8²

x² = 64 - 9

x² = 55

x = √55 ..........this is your answer in radical form.

x = 7.416

Answer:

x = √55 = 7.4162

Step-by-step explanation:

The Pythagorean Theorem states that a^2 + b^2 = c^2

so 3^2 + x^2 = 8^2

x^2 = 64 - 9 = 55

x = √55 = 7.4162

Step-by-step explanation:

Answer:

Firstly, we know 3^3 ÷ 3^-4 =2187. So, we got to check the value for each expression given below.

3x 3^6 = 2187

3^7 ÷ 3^0 = 2187

3^-3 ÷ 3^4 = 1/2187 (odd one out)

3^3 x 3^4 = 2187

Answer is 3^-3 ÷ 3^4

Step-by-step explanation:

To break the numbers down, 96.5% of all the Earth's water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact.

Answer:

-10 times the first equation and 3 times the second equation

Step-by-step explanation:

Multiply the first equation by 10 and the second equation by -3:

1.  1/5 x + 3/4 y = 9

x-10 ⇒  -2x - 15/2 y = -90

2.  2/3 x - 5/6 y = 8

x3 ⇒ 2x - 5/2 y = 24

Add the equations together:

     -2x - 15/2 y = -90

+      2x - 5/2 y = 24

         0x - 10y = -66

Answer:

(7, 1)

Step-by-step explanation:

translation = [tex]\left[\begin{array}{c}2\\-5\end{array}\right][/tex]

(2 units to the right and 5 units down)

Therefore, x coordinate = 5 + 2 = 7

y coordinate = 6 - 5 = 1

So translated point is (7, 1)

Answer:

(-2,-2)

Step-by-step explanation:

Step: Substitute 3x+4 for y in y=−x−4:

y=−x−4

3x+4=−x−4

3x+4+x=−x−4+x (Add x to both sides)

4x+4=−4

4x+4+−4=−4+−4 (Add -4 to both sides)

4x=−8

4x/4=−8/4(Divide both sides by 4)

x=−2

Step: Substitute −2 for x in y=3x+4:

y=3x+4

y=(3)(−2)+4

y=−2(Simplify both sides of the equation)

The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change (slope) and b is the y intercept.

Let y represent the cost of producing x number of beach balls.

Using the point (10000, 587500) and (50000, 717500):

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-717500=\frac{717500-587500}{50000-10000} (x-10000)\\\\y=3.25x+685000[/tex]

The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000

Step-by-step explanation:

Set up a ratio:

4/24 = x/60

Cross multiply and solve

4 * 60 = 24x

240 = 24x

10 = x, 10 mph

10 gallons every 45 days is ever 6 3/7 weeks

Answer:

The answer is √26

Step-by-step explanation:

Let the point be A and B i.e.,

A = (11, 7)

B = (16, 6)

Now, The distance between A and B

AB = √(x₂ – x₁)² + (y₂ – y₁)²

AB = √(16 – 11)² + (6 – 7)²

AB = √(5)² + (-1)²

AB = √25 + 1

AB = √26

Thus, The distance between A and B is √26
