Answer:

340 ft²

Step-by-step explanation:

From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).

First, find the area of the square.

Area of a square = width x length = 10 x 10 = 100 ft²

All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.

Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²

So the total area of all 4 triangles = 4 x 60 = 240 ft²

Therefore the total surface area = 100 + 240 = 340 ft²

Klio2033 [76]

Answer:

230 capsules.

Step-by-step explanation:

The following data were obtained from the question:

Taste >>>>>>>>>>> Frequency

Volluto >>>>>>>>>> 12

Livanto >>>>>>>>>> 7

Ristretto >>>>>>>>> 23

Cosi >>>>>>>>>>>> 3

Other >>>>>>>>>>> 5

Next, we shall determine the total frequency.

This is illustrated below:

Total frequency = 12 + 7 + 23 + 3 + 5

Total frequency = 50

Finally, we shall determine the number of Ristretto in 500 capsules.

This can be obtained as follow:

Number of Ristretto = Frequency of Ristretto /total frequency x total capsule

Frequency of Ristretto = 23

Total frequency = 50

Total capsule = 500

Number of Ristretto = 23/50 x 500

Number of Ristretto = 23 x 10

Number of Ristretto = 230.

Therefore, the number of Ristretto in the 500 capsules is 230.

Answer:

A. Division property of inequality

Step-by-step explanation:,

If a, b and c are any real numbers,

By the division property of inequality,

a = b ⇒ $\frac{a}{c}=\frac{b}{c}$ ,

By the inverse property of multiplication,

$a(\frac{1}{a}) = 1$

where, 1 is multiplication identity.

By the subtraction property of inequality,

a = b ⇒ a - c = b - c

By transitive property of inequality,

a = b and b = c ⇒ a = c,

Thus, it is clear that,

Division property of inequality is used in step 4.

Option A is correct.

Marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?

Marta_Voda [28]

Answer: First option.

Step-by-step explanation:

Marta needs to subtract $2\pi r^2$ from both sides of the equation:

$s=2\pi rh+2\pi r^2$

$s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2$

$s- 2\pi r^2=2\pi rh$

Now she needs to divide both sides of the equation by $2\pi r$ , then:

$h=\frac{s- 2\pi r^2}{2\pi r}$

Rewriting:

$h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}$

Simplifying, she should get:

$h=\frac{s}{2\pi r}-r$

This matches with the first option.
