GUYS I NEED THIS FAST PLS

Answers

Answer:

13.93 cm

Step-by-step explanation:

Given data

We have the

length = 5cm

Width = 12cm

Height= 13cm

The diagonal can be gotten by applying the Pythagoras Theorem using the Length and the Height

D^2= 5^2+13^2

D^2= 25+169

D^2= 169

D= √194

D= 13.928 cm

Hence the diagonal is 13.93 cm

Draw the following triangle after a 90° clockwise rotation about the origin.

Answers

Answer:

Its gonna be in the same spot but just on the left

Step-by-step explanation:

The graph is attached with the solution

What is rotation?

Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.

The coordinates of the vertices of the given triangle are (3,-2), (1,-5), and (5,-4).

The coordinate rule for 90° clockwise rotation about the origin is:

(x,y)→(y,-x)

Therefore, the vertices of the triangle are transformed as follows:

(3,-2) → (-2, -3)

(1,-5) → (-5,-1)

(5,-4) → (-4,-5)

Now, plot the image points (-2,-3), (-5,-1), and (-4,-5) and connect them to draw the required triangle.

The graph is attached with the solution.

2. A kitten is gaining 0.6 pounds per week. The kitten is currently seven pounds. After how many weeks will the kitten be at least 10 pounds?

Answers

Answer:

Here is the answer

Step-by-step explanation:

The kitten weighs_____pounds every week                    -0.6 pounds

Weight of the kitten at current time                                    -7 pounds

Weeks it will take for the kitten to reach 10 pounds         -0.6+7=7.6

                                                       now round it off and you will get 7

                            ∴the kitten will take 7 more weeks for getting to 10 pounds            

The kitten will be at least 10 pounds after 5 weeks. Let's set up an equation to solve for the number of weeks needed for the kitten to reach at least 10 pounds.

Let "w" represent the number of weeks.

The weight of the kitten after "w" weeks can be calculated as:

Weight = Initial weight + (Weight gained per week * Number of weeks)

Weight = 7 + (0.6 * w)

We want to find the number of weeks when the weight is at least 10 pounds:Weight ≥ 10

Substituting the equation for weight:

7 + (0.6 * w) ≥ 10

Subtracting 7 from both sides:

0.6 * w ≥ 3

Dividing both sides by 0.6:

w ≥ 3 / 0.6

w ≥ 5

Therefore, the kitten will be at least 10 pounds after 5 weeks.

Steps to determining the answer

Determine the quantity of soy sauce in one bottle by dividing 4/800 by 32The answer gotten in the above step is multiplied by 23 to determine the total amount of soy sauce in 23 bottles

Soy sauce in one bottle = total soy sauce in one bottle / total number of bottles

4/800 ÷ 32 =

4/800 x 1/32 = 1 / 6400

soy sauce in 23 bottles

1/6400 x 23 = 23/6400 ml or 0.003594 ml
