The Sum Of The Measures Of The Three Sides Of A Triangle Is 11 cm, and the Measure of the largest side is 5 cm, and the smallest side is 2 cm. find the measure of the largest Angle.
The library is located 1.8 miles west of Callie’s house. The grocery store is located 2.4 miles south of the library. What is the length of a straight line between Callie’s house and the grocery store?
Answers
Hello!
A good way to solve this is by using the Pythagorean Theorem, where the distance between the grocery store and Callie's house is the hypotenuse of the triangle.
The two legs we are given, 1.8 and 2.4 will represent a and b in the Pythagorean Theorem.
a²+b²=c²
First we have to find 1.8 and 2.4 squared.
1.8²=3.24 2.4²=5.76
If we add these answers, we will get 9. This is c². But to find just c, we will undo the square by using the square root.
√9=3.
This means that the length of a straight line from Callie's house to the grocery store is 3 miles.
I hope this helps!
A number increases by 10%, and then decreases by 10%. Will the result be greater than, less than, or equal to the original number?
Answers
one way it so try
100 increase by 10% 10% of 100=10 so 100+10=110
then decrease by 10% 10% of 110=11 so 110-11=99
original number=100 is 99 greater than or less or equal the original? 99<100 it is less
Hey there! The answer would be less than because 10% of the first number would be more than 10% of the second number. If you don't know what I mean then look at this as a example. 100*0.10=10, of you subtract 100 by 10 you get 90, 90*0.10=9, you add 90 by 9 you get 99, 99 is less than 100 (99<100). Do you see what I mean. If not feel free to message me. :)
If 28% of a sum is 100.80 what is the sum
Answers
$360.00*.28= 100.80
Or do a portion
28%/100%=100.8/x
Then cross multiply
10080=28x
x=360
Find the mean of this set of numbers.5, –11, 7, 12, –1, 0
A. 6
B. 2
C. –2
D. –6
Answers
mean is basically average basically find how many terms (there are 6 terms) then add them all together 5+-11+7+12+-1+0 =12 then divide the sum by the number of terms 12 divided by 6=12/6=2
the answer is 2 or B

5/6 - 1/6 = in simplest form
Answers
5/6 - 1/6 forget about the denominator since it's the same denominator 5 - 1 = 4 4/6 is the answer and 2/3 simplified :)
5/6 - 1/6 = 2/3 5-1=4 keep the dinominator. so u have 4/6. simplify by 2 , 4/6÷2=2/3
