Answer:

c and e

Step-by-step explanation:

Solution:

Note that:

Finding the area of the square:

The length of the square is 23.29 meters.

Area of triangle = 32.5 m²

Area of square = s²

Area of the square:

[tex]32.5 +[/tex] Area of square = [tex]575 m²[/tex]

Area of square = [tex]575 -32.5[/tex]

Area of square = [tex]542.5[/tex]

[tex]s² = 542.5[/tex]

[tex]s= \sqrt{542.5} = 23.29[/tex]

The length of the square is [tex]23.29[/tex] meters.

Answer:

[tex]\huge\boxed{\frac{48}{100}}[/tex]

Step-by-step explanation:

The same way that you can perform any (most) operation(s) on both sides of an equation, you can do the same to the numerator and denominator of a fraction.  Thus, simply multiply the numerator (4) and the denominator (10) to get 40/100 from 4/10.  Then, because 40/100 and 8/100 have the same denominator, simply add the numerators 40 and 8 to get 48/100.

Hope it helps :) and let me know if you want me to elaborate.

Answer:

B

Step-by-step explanation:

Because of 4/10 having 10 you have to times to it get's to 100 since the denominators isn't the same.

So how many times do you have to times to get to 100=?

10 is the correct answer so since you times 10 ten times now you will have to also times 4 by 10 what is 4 x 10=?

10 x 4=40 so now we can finally add.

40 + 8=48 out of 100 so out answer is 48/100

Do you want to see the answer in different form.

Like these

Decimal form=0.48

Percent form=48%

or written form= forty eight out of one hundred.

hope this helps have an awesome day:)

Answer: n = 13

Step-by-step explanation:

To find n, you can look at the equation and see that n is being multiplied by 3 to equal 24. Since 8 times 3 equals 24, you can substitute to solve:

8 = n - 5

n = 13

Therefore, through simplification, n is equal to 13.

I hope this helps!

Considering that the logo is composed by a semi-circle, a square and a right triangle, it's area is of 143.47 square inches.

The area of a semi-circle of radius r is given by:

[tex]A = 0.5\pi r^2[/tex]

In this problem, the radius is of r = 7 in, hence it's area in square inches is of:

[tex]A_{sc} = 0.5\pi \times 7^2 = 76.97[/tex]

The area of a square of side l is given by:

[tex]A = l^2[/tex]

In this problem, we have that l = 7 in, hence it's area in square inches is of:

[tex]A_{sq} = 7^2 = 49[/tex]

The area of a right triangle of sides a and b is given by:

[tex]A = \frac{ab}{2}[/tex]

In this problem, we have that a = 5 in, b = 7 in, hence it's area in square inches is of:

[tex]A_{rt} = \frac{5 \times 7}{2} = 17.5[/tex]

It is given by the sum of the areas of each figure, hence:

[tex]A = A_{sc} + A_{sq} + A_{rt} = 76.97 + 49 + 17.5 = 143.47[/tex]

It's area is of 143.47 square inches.

Step-by-step explanation:

I just used a pyramid calculator online and inputed the base and height.

The distance from the top of the pyramid, to each vertex of the base would be 10.5 unit.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

A right square pyramid has an altitude of 10 and each side of the base is 6. we need to find the slant height of the pyramid.

From the Pythagoras' theorem

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

[tex]s^2 = h^2 + (b/2)^2\\\\s^2 = 10^2 + (6/2)^2\\\\s^2 = 100 + 9\\\\s^2 = 109\\\\s = \sqrt109\\\\s = 10.5[/tex]

Thus, the distance from the top of the pyramid, to each vertex of the base would be 10.5 unit.

The expression 20x + 10y represents the profit and the maximum profit is N 470, and the greatest number of packets she buys is 50.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

A shopkeeper orders packets of soap powder. The cost price of a large packet is N180 and that of a small packet is N80.

Let's suppose the number of the large packets is x

The number of small packets is y.

The greatest number of packets she buys = 4000/80 = 50

The maximum amount can be spent = N 4000

180x + 80y ≤ 4000

Profit will be:

= 20x + 10y

The arrangements gave maximum profit:

x         y       Cost      Profit

10       27     3960      470

11        25     3980      470  

12       23      4000     470

The maximum profit = N 470

Thus, the expression 20x + 10y represents the profit and the maximum profit is N 470, and the greatest number of packets she buys is 50.

Answer:

Step-by-step explanation:

We already know 2 angles of each triangle, so we can find the third angle

The third angle of LMN = 180 - 115 - 21 = 54
The third angle of PQR = 180 - 21 - 49 = 110

So, the 3 angles of each triangle are not similar to each other
And there are no information about the sides.


So, I think the safest option is to go with "there's not enough information to determine whether they are similar or not."

But, the 3 sides of LMN by normal vision is longer than PQR, so you can also go with LMN is not similar to PQR.

Answer:

13 rabbits   15 turtles

Step-by-step explanation:

 T + R = 28

3T +5R = 110

    Multiply the first by -3 to eliminate T

-3T -3R =-84

3T + 5R = 110

    AD BOTH ( T will be cancelled)

 2R = 26

R = 13   (13 rabbits)

     28-13= 15 (15 turtles)

  13x5 = 65

  15x3 = 45

   13x5 =65

                     45+65 = $110
