2(pi)r = 9.4in
(pi)r = 4.7in
3.14r = 4.7in
r = 1.497in

Surface Area Of a Sphere = 4(pi)r^2 = [4(3.14)(1.497)^2]in^2 = 28.147in^2 = 28in^2
Volume Of a Sphere = 4/3(pi)r^3 = [4/3(3.14)(1.497)^3]in^3 =14.05in^3 = 14in^3

To the left of z = -0.95?

spin [16.1K]

I suspect you want the area under the standard normal curve to the left of z = -0.95.

On my calculator I typed in normal cdf(-100, -0.95) and got the result 0.171.

A piece of property lies between two parallel streets as shown. m<1=(2x+6)°,and m<2=(3x+9)°. What is the relationship betw

kolezko [41]

The angles are supplementary angles

The measure of angle m<1 and m<2 are 72 and 108 degrees respectively

Find the diagram attached. From the figure, the sum of the angles m<1 and m<2 are supplementary

Given the following angles

m<1 = 2x + 6

m<2 = 3x + 9

Since both angles are supplementary, hence;

2x + 6 + 3x + 9 = 180

5x + 15 = 180

5x = 180 - 15

5x = 165

x = 165/5

x = 33

Get the measure of m<1;

m<1 = 2x + 6

m<1 = 2(33) + 6

m<1 = 66 + 6

m<1 = 72degrees

Get the measure of m<2:

m<2 = 180 - m<1

m<2 = 180 - 72

m<2 = 108degrees

Hence the measure of angle m<1 and m<2 are 72 and 108 degrees respectively

What is the slope <br> y = (34/4)x + 3

statuscvo [17]

Answer:

The slope is 17 / 2.

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=17 / 2

b=3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 17 / 2

y-intercept: 3
