Answer:

The total square kilometers is 299.

Step-by-step explanation:

Area equals length times width.

Answer:

299km

Step-by-step explanation:

Area= LxW

13x23=299

so your answer would be 299 square kilometers!

Answer:

it should be 25 cm

Step-by-step explanation:

c=cm, y=years

10/2= 5,

Answer:

Step-by-step explanation:

Oo.24

Answer:

B. 73°

Step-by-step explanation:

The triangle is an isosceles triangle as it has 2 equal sides. This implies that the angles opposite to the two equal sides are of the same measure.

Therefore,

x = (180 - 34) ÷ 2

x = 146 ÷ 2

x = 73°

Answer:

140 minutes

Step-by-step explanation:

First divide 21 by 3 to get 7

Then do 20*7 to get 140 :)

Answer:

The point after the reflection of (-4,-3) across the y-axis is:

Hence, option B is correct.

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-4, -3)

Let say the point is A(-4, -3)

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-4, -3) → A'(-(-4), -3) → A'(4, -3)

Therefore, the point after the reflection of (-4,-3) across the y-axis is:

Hence, option B is correct.

Answer:

If it's 107% of 50 the answer would be 53.5

If it's 107% more than 50 it would be 103.5

Step-by-step explanation:

107% of 50 is 53.5

50 × 107% = 53.5

50 × 107% = 53.5

+50

--------

103.5

Answer:

160.5

Step-by-step explanation:

you but 107% 150 = what it well give you the answer

Answer:

10n+10

Step-by-step explanation:

10n+10

Explanation:

When n=0 that must mean that you always add 10. From there it's pretty obvious that it's increasing by 10 each time, meaning that you multiply n by 10 as well

Answer:

puede hacer 26 pisos y le sobran 4 galletas

Answer:

yes

Step-by-step explanation:

she needs 8 cups and 3 quarts is 12 cups

Answer:

Step-by-step explanation:

when 13 bought we find these inequalities

x + 12y < 7  no

2x + 11y < 7.5 no

3x + 10y < 8 no

4x + 9y < 8.5 no

5x + 8y >  9  yes

When 14 bought we find these inequalities

x + 13y < 7.5 no

2x + 12y < 8 no

3x + 11y < 8.5 no

4x + 10y > 9 yes  

We want to find and solve a system of inequalities to determine some possible solutions to Arianna's situation.

The possible solution is:

x = 2

y = 12

And the graph can be seen at the end.

Now let's see how to solve this.

First, we need to write the system of inequalities, the information given is:

Now we can define the variables:

Then we must have:

x + y ≥ 13   (this means that she buys at least 13 fruits)

x*$1 + y*$0.50 ≤ $9  (this means that she can't spend more than $9)

Now we just need to graph these two lines, we can rewrite them as:

y ≥ 13 - x

y ≤ $9.00/$0.50 - x*$1/$0.50 = 18 - x*2

Then we just need to graph the two lines, and shade the region above the first one, and the region below the second one, the graph can be seen below:

Any point inside the double shaded region in the first quadrant is a possible solution. (we restrict only to the first quadrant because we can not use negative values for x nor for y).

Then a possible solution that we could choose is:

x = 2

y = 12

This means that she buys 2 peaches and 12 mangos.

Answer:

5x³-13x²+24x+12

Step-by-step explanation:

Start by distributing (5x+2) into (x²-3x+6)

It is easiest to start with 5x.

When distributing 5x, your answer should be: 5x³-15x²+30x.

Then, distribute the 2 just as you did for 5x.

Your answer for that should be: 2x²-6x+12

After that, add the like- terms from both answers together.

5x³-15x²+30x+2x²-6x+12

The final answer is then: 5x³-13x²+24x+12

Answer:
