Answers

Answer 1

Answer:

3 miles x 5 week days = 15 miles

6.5 miles x 2 days over the weekend= 13

13 miles + 15 miles = 28

28 miles/ 7 days of the week= 4 miles on average per day

If two of a triangle,s angles measure 42 degrees and 48 degrees, how would you classify that triangle? A: acute angle
B: obtuse angle
C: right angle

Answers

If any of the angles are over 90 degrees, the triangle is classified as obtuse, if it's exactly 90 it's classified as a right triangle, and if all the angles are below 90 it is considered an acute triangle.

In this case you have 2 angles, 42 and 48, which seems to make the triangle acute. However, if you add them together and subtract from 180 (to find the third angle), you can find that the third angle is indeed 90 degrees, making it a right triangle.

How many terms are in the expression 12+r to the third power

Answers

Answer:

There are 4 terms in the expansion of the given expression $(12+r)^3$

Therefore $(12+r)^3=1728+r^3+432r+48r^2$

Step-by-step explanation:

Given expression is $(12+r)^3$

To find how many terms in the expansion of the given expression :

$(12+r)^3=12^3+r^3+3(12)^2r+3(12)r^2$

$=1728+r^3+3(144)r+48r^2$

$=1728+r^3+432r+48r^2$

Therefore $(12+r)^3=1728+r^3+432r+48r^2$

Advance says you can double your money in 10 years if you put $1,000 and a simple interest account What annual interest rate does the Bank pay

Answers

ok
I=PRT
P=present amount
I=interst
T=time in years
R=rate in percent

when you double your money, interest=present amount
I=1000=P
T=10 years
so
1000=1000(10)(R)
1000=10000R
divide both sides by 10000
0.10=R
