Answer:

The length of the radius of the sphere is 11.0 units

Step-by-step explanation:

we know that

To calculate the radius of the sphere, we can use the distance formula

d=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}+(z_2-z_1)^{2}}

where

d is the length of the radius

(x_1,y_1,z_1) is the center of the sphere

and

(x_2,y_2,z_2) is one point on the surface of the sphere

we have

(x_1,y_1,z_1)=(0,0,0)

(x_2,y_2,z_2)=(4,9,-5)

substitute in the formula

d=\sqrt{(4-0)^{2}+(9-0)^{2}+(-5-0)^{2}}

d=\sqrt{(4)^{2}+(9)^{2}+(-5)^{2}}

d=\sqrt{122}

d=11.0\ units

therefore

The length of the radius of the sphere is 11.0 units

Look back at the plans these students used to solve the word problem below.
MrRissso [65]

Answer:

A. Eva

Step-by-step explanation:

Given that

The entire school, 250 students, went to the soap box derby.2 vans went to soap box derby and each van held 6 students.

To find the total number of students from the Math Club who went to the soap box derby, we need to add the number of students in each van, the number of times equal to the number of vans.

i.e. by adding 6 (i.e. number of students in each van) 2 (number of vans )number of times, we can get the number of students from Math Club who went to the soap box derby.

Number of Math Club students who went to the soap box derby = 6 + 6 = 12

OR

Simply, multiply <em>number of students in each van </em>with the <em>number of vans .</em>

6 \times 2 = 12

Therefore, <em>Eva is correct </em>about the calculations.

What is the length of MN?<br><br> Round to the nearest tenth of a unit.<br><br> ??? Units
sesenic [268]

Answer:

  8.5

Step-by-step explanation:

The length of a segment can be found from its end coordinates by using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((8 -2)² +(4 -(-2))²) = √(6² +6²) = √72

  d ≈ 8.485 ≈ 8.5

The length of MN is about 8.5 units.
