Answer:

6.48m

Step-by-step explanation:

If you look at the values, you'll notice that the top 2 triangles have the same values and the bottom 2 triangles have the same values.

Area(Kite)=Area(Top Triangles)+Area(Bottom Triangles)

Area(Kite)=Area(15*18cm)+Area(21*18cm) (You can plug it in like a rectangle since their is 2 of each triangle)

Area(Kite)=270cm+378cm

Area(Kite)=678cm

Don't forget they asked it in Meters not Centimeters!

So...

The area of the kite is 6.48m

Answer:

6.48 sq. meters

Step-by-step explanation:

Let's split the kite into 2 parts. The bottom triangle and the top triangles.

Let's find the values of the bottom two triangles first. Both triangles have the same lengths and widths so their area will be the same too. The equation for the area of the triangle is (L*W)/2. The length is 21 and the width is 18. (21*18)/2=189. So since there are 2 triangles, you do 189*2= 378.

Let's find the values of the top two triangles. Since both of them have the same length and width, their areas will be the same too. Since we know the equation, let's use that to solve this problem. The length is 15 and the width is 18. (15*18)/2=135. So since there are 2 triangles, you do 135*2=270.

Now we have to add the areas of the 4 triangles together. 270+378=648 cm. But the answer has to be in meters so the answer is 6.48 since 1 cm = 0.01 m.

Sorry for the long explanation, I was trying to show my work so you would understand!

The equation for the linear function that relates temperature (x) and refreshment sales (y) from the considered option can be given by: Option C: y = 11x- 55

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.

For this case, we see that the option C: y = 11x - 55 is such that each term is having at max one variable (therefore 1 degree) or no variable (therefore 0 degree).

Thus, option C represents a linear equation. Its graph is given below.

Option A has [tex]x^2[/tex] which is two degree, Option B has two degrees in y, and in Option D, there is x with three degrees.

Thus, the equation for the linear function that relates temperature (x) and refreshment sales (y) from the considered option can be given by: Option C: y = 11x- 55

Answer:

2496 is the volume

Step-by-step explanation:

The height of the tank is 13, the water level is 3 inches below that so the height of the water would be 10 (13-3 = 10)

volume = length x width x height:

Volume = 24 x 8 x 10 = 1,920 cubic inches

1 gallon = 231 cubic in.

1920/231 = 8.31 gallons

Answer:

Zero

Step-by-step explanation:

Simplifying

12x + 1 = 3(4x + 1) + -2

Reorder the terms:

1 + 12x = 3(4x + 1) + -2

Reorder the terms:

1 + 12x = 3(1 + 4x) + -2

1 + 12x = (1 * 3 + 4x * 3) + -2

1 + 12x = (3 + 12x) + -2

Reorder the terms:

1 + 12x = 3 + -2 + 12x

Combine like terms: 3 + -2 = 1

1 + 12x = 1 + 12x

Add '-1' to each side of the equation.

1 + -1 + 12x = 1 + -1 + 12x

Combine like terms: 1 + -1 = 0

0 + 12x = 1 + -1 + 12x

12x = 1 + -1 + 12x

Combine like terms: 1 + -1 = 0

12x = 0 + 12x

12x = 12x

Add '-12x' to each side of the equation.

12x + -12x = 12x + -12x

Combine like terms: 12x + -12x = 0

0 = 12x + -12x

Combine like terms: 12x + -12x = 0

0 = 0

Solving

0 = 0

Answer:

324

Step-by-step explanation:

I think that 3x108 is 324  so I think the height is 324 and the base is 108.

Answer:

Base: 18cm

height: 12 cm

Step-by-step explanation:

Let the ratio be x

base = 3x  height = 2x

area of triangle = 108

⇒ 21 ×2x×3x=108

⇒3x 2 =108

⇒x 2 =36

x=6

Base=3x=3×6=18cm

height=2x=2×6=12cm.

Exponential equations are equation that contain powers or exponents in them. The simplified form of the given expression is [tex]\frac{\sqrt{y}}{xz^2}[/tex]

Given the exponential function expressed as

[tex](x^{1/2}y^{-1/4}z})^{-2}[/tex]

According to the law of indices expressed as

[tex](a^m)^n= a^{mn}[/tex]

Applying this law to the given exponential equation, we will have:

[tex]=(x^{1/2}y^{-1/4}z})^{-2}\\=(x^{1/2})^{-2}(y^{-1/4})^{-2}(z})^{-2}\\=x^{-1}y^{1/2}z^{-2}[/tex]

Using the inverse law;

[tex](x^{1/2}y^{-1/4}z})^{-2}=\frac{1}{x}\sqrt{y}\frac{1}{z^2}\\ (x^{1/2}y^{-1/4}z})^{-2}=\frac{\sqrt{y}}{xz^2}[/tex]

Hence the simplified form of the given expression is [tex]\frac{\sqrt{y}}{xz^2}[/tex]

Answer:

  600 miles

Step-by-step explanation:

The actual distances between the cities are expected to be proportional to those on the map.

__

  AB/(1.8 ft) = CD/(2.16 ft) . . . . ratio of miles to feet is constant

  CD = AB(2.16 ft)/(1.8 ft) = (500 mi)(6/5)

  CD = 600 mi

The actual distance between City C and City D is about 600 miles.

The answer is B as it is the only one that matches the 2 inequalities.

Answer:

250

Step-by-step explanation:

1. convert from percentage to decimal

to do this, divide the percentage by 100

1.11 / 100 = 0.0111

2. multiply the decimal by the amount

decimal = 0.0111

amount = 22500

final answer = 0.0111 * 22500 = 249.75 ≈ 250

thus, 1.11 % of 22,500 = 0.0111 * 22500 ≈ 22500
