Monica deposit 300 into a savings account that pays a simple interest rate of 4.3% call deposit 400 and into the savings account that pays simple interest rate of 4.2% Monica says she warren more interest in one year because her interest rate is higher is she correct

No

Step-by-step explanation:

MONICA:

Principal, p = 300

Simple interest, r = 4.3% = 0.043

CALL:

Principal, p = 400

Simple interest, r = 4.2% = 0.042

Amount, A received by each after one year :

Recall:

A = p(1 + rt) ; time, t = 1 year

MONICA:

A = 300(1 + 0.043(1))

A = 312.9

CALL = 400(1 + 0.042(1))

A = 416.8

Monica is incorrect, this is because amount earned is not only dependent on the interest rate but also the number of period and the initial or principal amount deposited.

Based on how the triangle looks and the directions given, you know that this is a right triangle.

You can use the Pythagorean Theorem, which is a^2 + b^2 = c^2, with c being the hypotenuse. If you plug in the values, you get

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

√100 = √c^2

c = 10

This means that Robert traveled 10 kilometers on the way back home, HOWEVER, it asks for the round trip distance. He traveled 14 km on the way there and 10 km on the way back, which means the round trip distance is 24 km.

I hope this makes sense!
