Find the value of x. i’m so lost. it’s geometry!

Answers

Answer 1

Answer:

150°

Step-by-step explanation:

Consider OACB,

Here <CAO =<CBO= 90° ( As they are tangents)

<ACB= 30°

Now, <CAO +<CBO+<ACB+x= 360°

90°+90°+30°+x= 360°

x= 150°

Hope it helps

Answer 2

Answer:

150°

Step-by-step explanation:

Construct a line OC, and consider the resulting triangles ΔOAC.

<AOB=(1/2)x

<CAO=90

<ACO=30/2=15

Angles in a triangle add to 180, so

90+15+(x/2)=180

x/2=75

x=150°

What is the image point of (-9,-2) after the transformation T-2,-5

Answers

Answer:

(-11, -7)

Step-by-step explanation:

The original point is (-9,-2)

The transformation you have to do is (x-2 , y-5)

This makes it so that you move the original point 2 units to the left (as a negative sign in the x value is towards the left side where the negative units are) and 5 units downwards (as a negative sign in the y value is on the negative side of the y-axis which is down)

So, your final answer would be (-9-2,-2-5) which is (-11,-7)

A camera company packs each camera in a cubeshaped box with side lengths of 1/2 ft. Then the company ships the cameras in a container with dimensions of 5 1/2 ft by 7 1/2 ft by 4 1/2 ft. What is the maximum number of camera boxes that will fit in the container?

Answers

The maximum number of camera boxes that can fit in the container is 1485.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

The volume of each camera box is given by the cube of the side length, which is (1/2)³ = 1/8 cubic feet.

The volume of the container is given by multiplying its length, width, and height, which gives:

= 5 1/2 ft x 7 1/2 ft x 4 1/2 ft
= 5.5 ft x 7.5 ft x 4.5 ft
= 185.625 cubic feet

To find the maximum number of camera boxes that can fit in the container, we need to divide the volume of the container by the volume of each camera box:

185.625 cubic feet / (1/8 cubic feet per camera box) = 1485 camera boxes

Therefore, the maximum number of camera boxes that can fit in the container is 1485.

4/5y - 8 = 2/5y + 16

Answers

Answer:

y=60

Step-by-step explanation:

trust

y = 60

Step-by-step explanation:

Step 1: Group all the x terms on the left side of the equation

Subtract y from both sides:

4/5y - 8 = 2/5y + 16

4/5y - 8 - 2/5y = 2/5y + 16 - 2/5y

2/5y - 8 = 2/5y + 16 - 2/5y

2/5y - 8 = 16

Step 2: Group all constants on the right side of the equation

Add 8 to both sides of the equation:

2/5y - 8 = 16

2/5y - 8 + 8 = 16 + 8

2/5y = 16 + 8

2/5y = 24

Step 3: Isolate the x

Multiply both sides by inverse fraction 52

2/5y = 24 5/2

2/5y 5/2 = 24

y = 24 5/2

y = 60
