Explanation:
The jump from CD = 2 to C'D' = 4 is "times 2". That must mean we go from BC = 3 to B'C' = 2*(BC) = 2*3 = 6. Therefore, x = 6.
-------
We could use a proportion to get the value of x as an alternative method:
(B'C')/(BC) = (C'D')/(CD)
x/3 = 4/2
2x = 3*4 ... cross multiply
2x = 12
x = 12/2 .... dividing both sides by 2
x = 6

Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 14,16,27
Answers
Answer:
this triangle is "obtuse
Step-by-step explanation:
Since sides 14 and 16 add up to 30, which is more than the third side, 27, we DO have a triangle here. The sides of lengths 14 and 16 form an angle greater than 90 degrees, and so this triangle is "obtuse." It's not a right triangle either, because the Pythagorean Theorem is not satisfied: 14^2 + 16^2 = 452, which is NOT 27^2.

Jenna's dogs used 999 chew toys last year. The animal shelter used 2,277 277 chew toys. How many times as many chew toys did the animal shelter use? How to do
Answers
Answer: 2.28 times
Step-by-step explanation:
When finding out the number of times more that the animal shelter used chew toys than Jenna's dogs, you need to divide the number used by the animal shelter by Jenna:
= Number used by animal shelter / Number used by Jenna's dogs
= 2,277 / 999
= 2.28 times
Notice that if you multiply Jenna's dogs 999 toys by 2.28 you will get approximately 2,277.

Step-by-step explanation:
In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.

what is the vaule of x I REALLY NEED HELP
Answers
Answer:
x = 69
Step-by-step explanation:
angles in a triangle add up to equal 180
which means that, x + x + x - 27 = 180
x + x + x = 3x
3x - 27 = 180
* add 27 to both sides *
-27 + 27 cancels out
180 + 27 = 207
207 = 3x
* divide both sides by 3 *
3x / 3 = x
207 / 3 = 69
we're left with x = 69

It can be worthwhile to work the last attachment (a) first, since these are all variations of the same triangle.
The Pythagorean theorem tells you the sum of the squares of the legs is the square of the hypotenuse.
Problem 6a:
3² +4² = x² . . . . fill in the given numbers; all measures in cm
9 + 16 = x² . . . . simplify exponents

Note that this triangle is a 3-4-5 right triangle. That is a set of side lengths (ratios) that is useful to remember. In this problem set, you see it again immediately.
__
Problem 6b:
Shortest-to-longest, the side ratios of the given triangle are ...
6 : x : 10
For some x', this is ...
3 : x' : 5 . . . . . . . . . . . . . matches a 3-4-5 triangle with x' = 4
The scale factor is 6/3 = 10/5 = 2, so we have ...
x = 2·x' = 2·4 = 8
x = 8 cm . . . . . with units
__
Problem 6c:
The side ratios are ...
x : 12 : 15 which reduces to x' : 4 : 5
This matches a 3-4-5 triangle with x' = 3, and a scale factor of 12/4 = 15/5 = 3.
Then ...
x = 3·x' = 3·3 = 9
x = 9 m . . . . . with units
The Fitzgerald paid $3,200 to heat their home in the year of 2018. By the end of the year 2019, they saw the cost of heating their home rose to $3,516 for the year. What could be use to find the difference in what they paid from 2918-2019?

Answer:
Substraction
Step-by-step explanation:
Given that
The amount paid in the year 2018 is $3,200
And, in the year 2019 the amount paid is $3,516'
We need to find the differnece between two years so how we can find
Basically we need to subtract the amount i.e.
= $3,516 - $3,200
= $316
hence, the difference is of $316 from 2018 to 2019

Answers
Answer:
Liters
Step-by-step explanation:
a Mili(thousandth)liter is a small unit of volume. Liters( a thousand milliliters) is the base unit of volume and larger, so it's B.
The requried to wash her car, Amy used 25 liters of water. Option B is correct.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
Here,
The question doesn't specify what unit of measurement the 25 refers to, so it's unclear whether the answer should be in milliliters or liters. However, assuming that the unit of measurement is liters, the answer would be:
Amy used 25 liters of water to wash her car.
If the unit of measurement is milliliters, the answer would be:
Amy used 25,000 milliliters of water to wash her car.
Note that 1 liter is equal to 1000 milliliters, so 25 liters is equal to 25,000 milliliters.
Thus, the requried To wash her car, Amy used 25 liters of water. Option B is correct.
