Answer:

m<A > m<B > m<C

Step-by-step explanation:

In triangles, the measure of angles is proportional with the side length's they see,

The angle with the biggest the biggest measure sees the biggest side length

in triangle ABC the side lengths are given as

BC = 14, CA = 13 and AB = 5

from this, we can conclude:

m<A > m<B > m<C

Hector invests $800 in an account that earns 6.98% annual interest compounded semiannually. Rebecca invests $1000 in an account
Roman55 [17]
A=P (1+r/n)^nt

A= Total amount invested, P=principal amount, r=Interest rate, n=number of time in a year when the interest is earned (for annual, n=1; for semi-annual, n=2, ...), t = time in years

In the current scenario, case 1, n=2; case 2, n=1 and A1=A2, t1=t2
Therefore,
800(1+0.0698/2)^2t = 1000(1+0.0543/1)t
Dividing by 800 on both sides;
(1+0.0349)^2t = 1.25(1+0.02715)^t
(1.0349)^2t = 1.25(1.02715)^t
Taking ln on both sides of the above equation;
2t*ln (1.0349)= ln 1.25 + t*ln (1.02715)
2t*0.0343 = 0.2231+ t*0.0268
0.0686 t = 0.2231+0.0268 t
(0.0686-0.0268)t = 0.2231
0.0418t=0.2231

t=5.337 years

Therefore, after 5.337 years or 5 years and approximately 4 months, their value of investments will be equal.

This value will be,
A=800(1+0.0698/2)^2*5.337 = $1,153.76

The area of a rectangle having breadth is 2.6m is 18.33 sq.m. Find the<br> length of the rectangle.
uysha [10]

Answer:

Hight=7.04mt

Step-by-step explanation:

The area of a rectangle is the result of multiply two touching sides

Area=Length*Heght (1)

We have one its sides (2,6m).

The other side can be otained using the equation (1) where Area= 18.33 sqm

18.3sqm=2.6m* Height

Lets divide the whole expression by 2.6m

18.3 sqm / 2.6 m= 2.6m * Height

Hight=7.04mt
