Step-by-step explanation:

Perimeter of figure

= 5 + 2 \times 7 +  \pi \: r \\   = 5 + 14 + 3.14 \times 5 \\  = 19 + 15.70 \\  = 34.70 \: in \:

the perimeter of a rectangle is twice the sum of its length and its width. The perimeter is 34 meters and it’s length is 2 meter
-Dominant- [34]

Here is your answer

Let the widht of rectangle be x metres

Then, its length= x+2 metres

Perimeter= 2 (l+b)

=> 34 = 2 (x+2 + x)

=> 34/2 = 2x+2

=> 17= 2x+2

=> 2x= 17-2

=> x = 15/2 metres

Width= 15/2 metres

Length= 15/2 + 2

= 19/2 metres

Given the triangle below, what is m triangleA, rounded to the nearest tenth?
Neko [114]

Answer:

The correct answer is option A   17.8°

Step-by-step explanation:

From the figure attached with this answer,

We can see a perpendicular from B to side AC

<u>To find BD</u>

In triangle BDC, its angles are 30°, 60° and 90°

Therefore the sides are in the ratio 1 :√3 : 2

Here BC = 11

BD : DC : BC = 1 :√3 : 2 = 11√3/2 : 11/2 : 11

Therefore BD = 11/2

<u>To find the value of  m<A</u>

We have

Sin ∅ = Opposite side /Hypotenuse

AB = 18 and BD = 11/2

Sin A = BD/AB =(11/2)/18 = 11/36 = 0.3055

m<A = Sin⁻¹(0.3055) = 17.79 ≈ 17.8°

Therefore the correct answer is option A  17.8°

CAN SOMEONE HELP ME WITH QUESTION 3. PLEASE SHOW YOUR WORK
oee [108]
Let 
x = number of liters of the 40% salt solution 
y = number of liters of the 20% salt solution 

The two amounts (x and y) must combine to 1500 liters, so 
x+y = 1500
we can solve for y to get
y = 1500-x
after subtracting x from both sides

---------------------------------------------------

If we have x liters of the 40% salt solution (composed of pure salt plus other stuff) then we have exactly 0.40*x liters of pure salt. Simply multiply the decimal form of the percentage with the amount of solution. 

Similarly, if we have y liters of the 20% solution, then we have 0.20*y liters of pure salt

Combined, we have 0.40*x + 0.20*y liters of pure salt all together. 

We want 1500 liters of a 28% solution, so we want 1500*0.28 = 420 liters of pure salt

Equate the two expressions (0.40*x + 0.20*y and 420) to get
0.40*x + 0.20*y = 420

---------------------------------------------------

We have the equation 0.40*x + 0.20*y = 420 and we also know that y = 1500-x

Let's use the substitution property now

0.40*x + 0.20*y = 420
0.40*x + 0.20*( y ) = 420
0.40*x + 0.20*( 1500 - x ) = 420 ... note how y is replaced with 1500-x

Now we can solve for x
0.40*x + 0.20*( 1500 - x ) = 420
0.40*x + 0.20*(1500) + 0.20*(-x) = 420
0.40*x + 300 - 0.20x = 420
0.40*x - 0.20x + 300 = 420
0.20x + 300 = 420
0.20x + 300 - 300 = 420 - 300
0.20x = 120
0.20x/0.20 = 120/0.20
x = 600

Now that we know x, use this to find y
y = 1500-x
y = 1500-600 ... plug in x = 600 (ie replace x with 600)
y = 900
---------------------------------------------------
---------------------------------------------------

Answers:

We need 600 liters of the 40% solution
We need 900 liters of the 20% solution
