Answer:
a) 5 cm
b) 8 cm
c) 9 m
Step-by-step explanation:
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
25 = x² . . . . . . . simplify sum
x = √25 = 5 . . . take the square root.
x = 5 cm . . . . . . apply units
__
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

A. ________________ of these pairs of identical triangles can be composed into a rectangle. B. ________________ of these pairs of identical triangles can be composed into a parallelogram.
The question is incomplete. The complete question is :
Discuss your responses to the first question with your group. Then, complete each of the following statements with all, some, or none. Sketch 1–2 examples to illustrate each completed statement.
A. ________________ of these pairs of identical triangles can be composed into a rectangle.
B. ________________ of these pairs of identical triangles can be composed into a parallelogram.
Solution :
A. None
None of the identical triangles provided in the sketch can be composed into a rectangle, it can be formed into a square. A rectangle is a quadrilateral with four sides having opposite side equal in length. The two adjacent sides of a rectangle are different in size. Thus a rectangle cannot be a square.
B. All
All of the figures provided in the sketch can formed a parallelogram. Two identical triangles can always be composed into a parallelogram by the segments that connects the opposite vertices.
To wash her car, Amy used 25 ? of water
A)millilters
B)liters
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.

Answer:
[tex]\sec \theta + \csc \theta = \frac{2\cdot \sqrt{3}+6}{3}[/tex]
Step-by-step explanation:
We proceed to simplify the given trigonometric expression into a form with a single trigonometric function:
1) [tex]7\cdot \sin^{2}\theta + 3\cdot \cos^{2}\theta = 4[/tex] Given.
2) [tex]4\cdot \sin^{2}\theta + 3\cdot (\sin^{2}\theta + \cos^{2}\theta) = 4[/tex] Definition of addition/Associative and distributive properties.
3) [tex]4\cdot \sin^{2} \theta +3 = 4[/tex] [tex]\sin^{2}\theta + \cos^{2}\theta = 1[/tex]/Modulative property
4) [tex]4\cdot \sin^{2}\theta = 1[/tex] Compatibility with addition/Existence of additive inverse/Modulative property
5) [tex]\sin \theta = \frac{1}{2}[/tex] Compatibility with multiplication/Existence of multiplicative inverse/Modulative property/Definition of division
6) [tex]\theta = \sin^{-1} \frac{1}{2}[/tex] Inverse trigonometric inverse.
7) [tex]\theta = 30^{\circ}[/tex] Result.
By Trigonometry, we know that secant and cosecant functions have the following identities:
[tex]\sec \theta = \frac{1}{\cos \theta}[/tex], [tex]\csc \theta = \frac{1}{\sin \theta}[/tex] (1, 2)
In addition, we know that [tex]\sin 30^{\circ} = \frac{1}{2}[/tex] and [tex]\cos 30^{\circ} = \frac{\sqrt{3}}{2}[/tex], then the sum of the two trigonometric function abovementioned is:
[tex]\sec \theta + \csc \theta = \frac{1}{\cos \theta} + \frac{1}{\sin \theta}[/tex]
[tex]\frac{2}{\sqrt{3}} + 2 = \frac{2\cdot \sqrt{3}}{3} + 2[/tex]
[tex]\sec \theta + \csc \theta = \frac{2\cdot \sqrt{3}+6}{3}[/tex]

Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 14,16,27
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.

what is the vaule of x I REALLY NEED HELP
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
Write the following word phrases as inequalities: Seven times a number increased by one is at most twelve. If you need these symbols, please copy and paste: ≥ or ≤
Answer:
7x+1 ≤12
Step-by-step explanation:
The common letter used to represent a variable is x. Thus, a 7 is added to it to signify that it is being multiplied. Then, increased by one means +1. At most is a fancy word for less than or equal to ( ≤).
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
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.

We have to find the equivalent expression
Here we use the exponent rule:
Which exponent rule we use here?[tex]a^b\cdot a^c=a^{b+c}\\[/tex]
here base is the same of both the number
If base are same then we can add the exponent
Therefore,In a given expression base is 5 therefore the
[tex]5^{12}\cdot5^{85}=5^{12+25}\\5^{12}\cdot5^{85}=5^{97}[/tex]
Therefore the given expression [tex]5^{12}\cdot5^{85}[/tex]equivalent to the [tex]5^{97}[/tex].
