Answer:
The perimeter is:
(3rd option) 2(x + y)
(5th option) 2x + 2y
The area is:
(7th option) xy
Step-by-step explanation:
Perimeter = the length (represented by y) + the width (represented by x) + length + width
Another way to state this is multiplyimg length by 2 and width by 2 and then adding them together as this equals the same outcome
Area = length (y) × width (x)

Answer:
13.3 = t
31.3= s
Step-by-step explanation:
Remember that sinθ = [tex]\frac{opposite}{hypotenuse}[/tex], cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex], and tanθ = [tex]\frac{opposite}{adjacent}[/tex]. (A good mnemonic to remember this is SOH-CAH-TOA).
Knowing this is true, we can solve for t and s.
sin(23°) = [tex]\frac{t}{34}[/tex]
34sin(23°) = t
13.3 = t
cos(23°) = [tex]\frac{s}{34}[/tex]
34cos(23°) = s
31.3= s

simplify 9/1/3 and show work. Thank you!
Answers
Answer:
27.
Step-by-step explanation:
9 / 1/3
= 9 * 3/1
= 9 * 3
= 27.
Exact Form: 28 /3
Decimal Form: 9. 333
First keep the denominator how it is.
To get the the numerator multiply the 9 by the denominator which is 3 so you will get 27. Then add the numerator which is 1 to 27 so you will get 28.
So the answer is 28/3 in exact form. To convert it to decimal form you just multiply 28 by 3.

y = __ √_ ????

Answers
Answer:
Here we have two triangle rectangles, and we want to know the value of y, the shared cathetus between them.
First, we know that one of them has an angle of 60° and the adjacent cathetus to it is a.
The other has an angle of 30° and the adjacent cathetus is b.
In both cases, the opposite cathetus is y.
Now we can recall the relationship:
Tan(a) = (opposite cathetus)/(adjacent cathetus)
Then we can write:
tan(60°) = y/a
tan(30°) = y/b
And we also know that:
a + b = 15
Then we have 3 equations:
tan(60°) = y/a
tan(30°) = y/b
a + b = 15
To solve this, we first need to isolate one variable in one of the equations, i will isolate a in the third equation:
a = 15 - b
Now we can replace it in the first equation to get:
tan(60°) = y/(15 - b)
i will rewrite this one as:
tan(60°)*(15 - b) = y
then our system is:
tan(60°)*(15 - b) = y
tan(30°) = y/b
now we can isolate b in the second equation to get:
b = y/tan(30°)
and then replace it on the other equation to get:
tan(60°)*(15 - y/tan(30°)) = y
Now we can remember that:
tan(60°) = √3
tan(30°) = (√3)/3
Replacing these in our equation we get:
√3*(15 - y/((√3)/3)) = y
we can rewrite this as:
√3*(15 - y*3/√3) = y
then:
(√3)*15 - y*3 = y
(√3)*15 = y + y*3
(√3)*15 = 4*y
(√3)*15/4 = y
then we get:
[tex]y = \frac{15}{4} *\sqrt{3}[/tex]

step 2. 28/54 = (2x+ 8)/(5x - 4)
step 3. 28(5x - 4) = 54(2x + 8) (cross multiplication)
step 4. 14(5x - 4) = 27(2x + 8) (divide both sides by 2)
step 5. 70x - 56 = 54x + 216 (distributive property)
step 6. 16x = 272 (group x's and add 56 to both sides)
step 7. x = 17 (divide both sides by 16).
