PLEASE SAVE ME FROM FAILING ( PICTURE BELOW)
Grace [21]

Answer:

5x + 10 + 2x - 5 = 180

7x + 5 = 180 \\  - 5 \:  \:  \:  \:  \:  - 5

7x = 175

\frac{7x}{7}  =  \frac{175}{7}

x = 25

5x + 10

5(25) + 10

125 + 10 = 135

find the volume of a right circular cone that has a height of 2.1m and a base with a diameter of 13.7m. round your answer to the
Nikolay [14]

Answer:

Volume of the cone = 103.14 meter cube

Step-by-step explanation:

Height of the cone= 2.1 m

Diameter= 13.7 m

Radius= 13.7/2= 6.85 m

Volume of a cone :

            =\pi r^2\frac{h}{3}

As, \pi =\frac{22}{7}=3.14

Putting the values in the formula:

Volume is :

            =3.14*(6.85*6.85)*\frac{2.1}{3} \\\\=3.14*(6.85*6.85)*0.7\\\\=3.14*46.92*0.7\\\\=3.14*32.85\\\\=103.14m^3

The volume of the cone is 103.14 meter cube

The first step here is to arrange the data set's form least to greatest,

Sherelle:  26, 39, 56, 58, 60, 62, 65, 66, 66, 68, 71, 72, 72, 73, 74, 75, 81, 83, 84, 85

Venita:  44, 45, 51, 51, 53, 53, 55, 57, 58, 62, 65, 66, 69, 69, 70, 73, 75, 77, 78, 79

Now we can determine our 5 - number summary based on the numbers respective positions.

First Data Set,

<u>(Five - Number Summary) - Minimum : 26, Quartile 1 : 60, Median : 69.5, Quartile 3 : 75, Maximum : 85 </u>

Second Data Set,

<u>(Five - Number Summary) - Minimum : 44, Quartile 1 : 53, Median : 63.5, Quartile 3 : 73, Maximum : 79</u>

Step-by-step explanation:

slope-intercept form: y = mx + b

m = slope (-3)

b = y-intercept (3)

y = -3x + 3

after plugging the function into desmos.com, the graph shows an x-intercept of the line at 1.
