Answer:
54.6 cm : B
Step-by-step explanation:
Mathematically the area of a rectangle is 2( l + b)
So in practical terms we only need the measure of two sides as we have 2 equal sides for a rectangle.
We can see that we have two right angles on each sides
Now to find b, we can use trigonometric ratios
For each of the rectangles, the diagonal represents the hypotenuse
Mathematically;
sin 30 = b/20
From triangle ABC
b = 20 sin 30 = 20 * 0.5 = 10 cm
Now, to get l
Mathematically;
Sin 60 = l/20
l = 20 sin 60 = 17.32 cm
So the perimeter is;
2(10 + 17.32)
2(27.32) = 54.64 cm which is 54.6 to the nearest tenth
Cancelling out both the -6 we get 12=0 which is not true, hence the equation is incorrect.
Answer:
10
Step-by-step explanation:
As we can see in hint through it we can identify that it is right angled triangle so here
AB = 6
FE = BC ( being corresponding sides of congruent triangle)
BC = 8
Now In triangle ABC
perpendicular (p) = 6
base (b) = 8
hypotenuse (h) = ?
By using Pythagoras theorem we get
h = √ p² + b²
= √ 6² + 8²
= √ 100
= 10
So Now
AC = h = 10

Answer:
Credit cards typically have high interest rates compared to most other types of loans. That means it’s potentially expensive to borrow money with a credit card. When you don’t pay your full credit card balance every month, it’s easy to accumulate boatloads of interest fees quickly.
What is a credit card minimum payment? It’s the minimum amount of money a credit card company is willing to accept each month to keep your account in good standing.
Don’t make the mistake of thinking the minimum due is a “monthly payment” you should be making to pay off your credit card bill. When you only pay the minimum due on your credit card statement, your credit card issuer will make a lot of extra money from you.
Step-by-step explanation:
Well to simplify it we combine the x's: 4x+11, then to solve for x:
4x= -11
x= -11/4
