Answer:

1134.08 m²

Step-by-step explanation:

To calculate the area of grass, subtract the area of the polygon from the area of the large green rectangle.

area of a triangle = 1/2 x base x height

area of a rectangle = width x length

area of large (green) rectangle = 40 x 36 = 1440 m²

area of regular 8-sided polygon = 4 triangles + 2 small rectangles + large rectangle

= 4(1/2 x 5.6 x 5.6) + 2(8 x 5.6) + (8 x 19.2) = 305.92 m²

Therefore, area of grass = 1440 - 305.92 = 1134.08 m²

Answer: Your answer is B

Step-by-step explanation:

Option B) A₁ = 50.3in², A₂ = 113.1in², A₃ = 176.7in² is the correct answer.

A circle is simply a closed 2-dimensional curved shape with no edges or corners.

Area of a circle is expressed as;

A = πr²

Where r is the radius of the circle and π is pi ( π = 3.14159 ).

For cake A;

From the previous expression of area of a circle

Area of A = πr²

Area of A = 3.14159 × (4in)²

Area of A = 3.14159 × 16in²

Area of A = 50.23in²

Hence, the area of the first cake is 50.23in².

For cake B;

From the previous expression of area of a circle

Area of B = πr²

Area of B = 3.14159 × (6in)²

Area of B = 3.14159 × 36in²

Area of B = 113.1in²

Hence, the area of the second cake is 113.1in².

For cake C;

From the previous expression of area of a circle

Area of C = πr²

Area of C = 3.14159 × (7.5in)²

Area of C = 3.14159 × 56.25in²

Area of C = 176.7in²

Hence, the area of the third cake is 176.7in².

Option B) A₁ = 50.3in², A₂ = 113.1in², A₃ = 176.7in² is the correct answer.

Hence;

Area of the first cake is 50.23in².

Area of the second cake is 113.1in².

Area of the third cake is 176.7in².

Answer:

You want to start by making 2 equations, first to show the sum and another to show the relationship between the two.

x + y = 32

3y = x

Now you want to substitute what you know:

y + (3y) = 32

*now solve

4y = 32

y = 32/4

y = 8

And now you want to plug in what you know into the first equation to solve for x

x + y = 32

x + 8 = 32

x = 32 - 8

x = 24

Now you know:

x = 24

y = 8

Answer:

a. 6x^2+x+0.7

b. 5x^2-2x-2

Step-by-step explanation:

a. 6x^2+2x-3-x+4.7-1

Simplest form is when all the terms are ordered by power and like terms are combined. I'm assuming the first term is 6x^2 because 6x2 seems a bit odd to me. When you combine like terms and reorder everything, you get

6x^2+x+0.7

b. 6x^2+2x-3-x^2-4x+1

The first thing I did was distribute the negative. Next, you just repeat the same steps. Combine like terms and reorder. The final result is:

5x^2-2x-2

(x,y)=(−26,68). Explanation: I'll solve this by first eliminating the y terms in both equations: E1:8x+3y=−4⇒16x+6y=−18

The weight of all 40 apples in the second box is : 144 x 40 = 5760 (g)

The total weight of all 90 apples in both boxes : 5760 + 6300 = 12060 (g)

To find the mean weight of an apple in the big container, we take the total weight of both boxes (12060) divided by the total amount of quantities (apples in both boxes)

So, the mean weight of an apple in the big container is 12060 : 90 = 134(g)

Answer:

also 75°

Step-by-step explanation:

the angles across each other at a crossing point of 2 lines must be equal.

so, 2 = 3.

and the angles at the crossing point with a parallel line are simply a "mirror" or rather a copy of the angles at the crossing point with the first line.

so, 2 = 3 = 6 = 7

and 1 = 4 = 5 = 8

The value of the measure of 7 is,

⇒ ∠7 = 75°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Two parallel lines are cut by a transversal.

And, the measure of 2 is 75°.

Here, Angle 2 and 3 are vertically opposite angle.

Hence, angle 2 and 3 are equal.

And, Angle 3 and 7 are alternate angle.

Hence, We get;

⇒ ∠3 = ∠7

So, ∠7 = 180°

Thus, The value of the measure of 7 is,

⇒ ∠7 = 75°

Answer:

(-3,-4)

Step-by-step explanation:

When reflecting across the y-axis, you will mirror the coordinates across the y-axis. This means (5,-4) will turn into (-5,-4) because mirroring it across the y-axis will only change the x coordinate. Then, to translate it to the right, you move to the right two times to give you (-3,-4). The y-coordinate will never change in this situation because you are only reflecting and moving left and right.

Answer:

2

Step-by-step explanation:

Let's test the values at x=2.

when x=2, g(2)=2, but f(2)=1.

This means that g(x)=(2/1)f(x)=2f(x).

The value of k for the function will be equal to 2.

The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.

Given that the two graphs are there in the image for the functions g and f. Function g is defined as g(x) = kſ (x).

The value of k will be calculated as,

Let's test the values at x=2.

when x=2, g(2)=2, but f(2)=1.

The function can be written as,

g(x)=(2/1)f(x)

g(x) =2f(x).

Therefore, the k value will be 2.

Okay so on 7 you first need to figure out the amount of people in each grade and then you need to look at the premade answers and try to split it up AND on the total part you need to put how many people all together. If I'm not mistaken, I'm pretty sure there are more right-handed people, then left-handed people on 7th graders.

Percentage is a way to describe a part of a whole. The equation can be used to find the regular price of the helmet,h is 0.7(h+85)=74.90.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As we know that all of the items in the bicycle shop are on sale for 30% off, therefore, the cost of each item will be 70% of the real cost. Now, the total amount was spent is $74.90. Thus, if we represent the helmet by h, and bicycle by b, then

[tex]70\%Helmet + 70\%Bicycle = \$74.90\\\\0.70 h + 0.70B = 74.90[/tex]

Taking 0.7 as the common,

[tex]0.7(h+B)=74.90[/tex]

As we know that the regular price of the bicycle(B) is $85, therefore, the equation can be written as,

[tex]0.7(h+85)=74.90[/tex]

Hence, the equation can be used to find the regular price of the helmet,h is 0.7(h+85)=74.90.

Answer:

7.5

Step-by-step explanation:

7.5 is the coefficient of x

Answer:

42 yd²

Step-by-step explanation:

Area of a rectangle = width x length

lateral surface area is the area of the sides only

So the difference between the total surface area and the lateral surface area would be the surface area of the ceiling and floor (top and bottom).

area of floor and ceiling = 2(3.5 x 6) = 42 yd²

Or, we can calculate the total surface area and lateral surface area, then find the difference:

total surface area = 2(3.5 x 4.2) + 2(4.2 x 6) + 2(3.5 x 6) = 121.8 yd²

lateral surface area = 2(3.5 x 4.2) + 2(4.2 x 6) = 79.8 yd²

difference = 121.8 - 79.8 = 42 yd²
