Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right

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.

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

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.

Brian buys 32 bottles of soy sauce, in total he has 4/800 ml of soy sauce. How much soy sauce would he have if he bought 23 bottles of soy sauce?
Answers
Answer:
23/6400 ml or 0.003594 ml
Step-by-step explanation:
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 bottlesSoy 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
