A ratio shows us the number of times a number contains another number. The ratio of the sides, base area, and volume are equal to 3:1, 9:1, and 27:1, respectively.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

Given the two lateral sides of the pyramids, therefore, the ratio of the sides of the pyramid can be written as,

Length of pyramid A: Length of pyramid B = 15:5 = 3:1

Let the length of the base of the pyramid is represented by a.

The ratio of the base area can be written as,

Area of Base of A: Area of base of B = (3a)²:a² = 9:1

The ratio of the volume can be written as,

Volume of A: Volume of B = (3l×3b×3h)/3 : (lbh)/3 = 27:1

Hence, the ratio of the sides, base area, and volume are equal to 3:1, 9:1, and 27:1, respectively.

Which graph can be used to solve the equation 2x-1=x+2
vlabodo [156]
The graph in the top right—-when trying to figure these out, just plug numbers in for x to find the y.
For example: plug 0 in for x on both equations—
2^0 -1=0 so you get it passing thru 0,0
0+2=2 so it passes through 0,2

(Distance/midpoint formula) - triangle ABC has vertices on the coordinate plane at A(-6.3, 7.2) B(2.2, 4.4) and C(5.6, -3.4) fin
Roman55 [17]

Answer:

8.51 units

Step-by-step explanation:

Given:

A(-6.3,7.2),B(2.2,4.4), C(5.6,-3.4)

Length of BC can be obtained using distance formula.

For two points A(x_{1},y_{1}) and B(x_{2},y_{2}), length of AB is given as:

AB=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

Plug in 2.2 for x_{1}, 4.4 for y_{1}, 5.6 for x_{2}, and -3.4 for y_{2}. Solve for BC

BC=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\ BC=\sqrt{(5.6-2.2)^{2}+(-3.4-4.4)^{2}}\\ BC=\sqrt{3.4^{2}+(-7.8)^{2}}=\sqrt{72.4}=8.51

Therefore, the length of BC is 8.51 units.
