Answer:25 in^2
Step-by-step explanation:
d1=10 d2=5
area of rhombus=( d1 x d2)/2
Area of rhombus=(10x5)/2
area of rhombus=50/2
Area of rhombus=25 in^2
Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.
(a+b+c)/3 =138
(a+b)/2 =136
a+b=272
a=272-b
(b+c)/2 =125
b+c=250
c=250-b
Sub a=272-b and c=250-b into (a+b+c)/3 =138,
(a+b+c)/3 =138
[(272-b)+b+(250-b)]/3 = 138
272-b+b+250-b = 414
-b = -108
b=108
From the above,
a=272-b
=272-108
a=164
c=250-b
=250-108
c=142
∵ a=164
b=108
c=142
∴ Adrian baked 164 cookies.
Bobby baked 108 cookies.
Calvin baked 142 cookies.
Answer:
Step-by-step explanation: How do you find the 3rd angle of a triangle?
Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.
The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.
First convert the 2 1/2 into eighths to be able to subtract the numbers. That becomes 2 4/8. Next set up the subtraction. 11 1/8 - 2 4/8. Note that 4/8 is bigger than 1/8, meaning we have to borrow 8/8 from 11 making our problem 10 9/8 - 2 4/8. Now we subtract as normal: 10 - 2 = 8; 9/8 - 4/8 = 5/8.
Final answer: 8 5/8 inches
we conclude that the inequality can be written as the compound inequality:
m < 8
m > 20
<h3>
</h3><h3>
How to solve the inequality for m?</h3>
Here we have the inequality:
3*|14 - m| > 18
We want to isolate m, so we start by dividing both sides by 3:
|14 - m| > 18/3 = 6
Now we can decompose the inequality in two:
14 - m > 6
14 - m < - 6
Solving both for m, we get:
14 - 6 > m
14 + 6 < m
8 > m
20 < m
Then we conclude that the inequality can be written as the compound inequality:
8 > m
20 < m
