Answer:
The base is 
and the height is 
Step-by-step explanation:
we know that
The area of the triangle is equal to
where
b is the base of triangle
h is the height of triangle
In this problem
----> equation A
so
-----> equation B
Substitute equation A in equation B
Solve the quadratic equation by graphing
The solution is 
see the attached figure
Find the base b
All you have to do is break this image into parts of two different shapes and find the areas of those two shapes. Then you can add them together and you will have your answer. Your work should look like this:
For one of the rectangles:
Length * Width
8 * 10 = 80
For the other rectangle:
Length times width
10 - 5 = 5 (You have to subtract 10 - 5 because you need to know the measurement of the of the width of the top rectangle, and the top rectangle is not a full 10 inches like the bottom one. )
15 - 8 = 7 (For the same reason as the width, you also need to subtract to find the length of the top rectangle.)
Now multiply.
Length * width
5 * 7 = 35
Now that you have the two areas of the two separate rectangles, you can add them together.
35 + 80 = 115
Answer:
D 1/4
Step-by-step explanation:
Your question is a problem in reading comprehension. It tells you its own answer.
x is always 1/4
One <u>possible inequality</u> is:
299m+261j ≥ 1000.
Explanation:
m is the number of cups of milk and j is the number of cups of juice.
Each cup of milk contains 299 mg of calcium. This gives us 299m mg of calcium for m cups of milk drank.
Each cup of juice contains 261 mg of calcium. This gives us 261j mg of calcium for j cups of juice drank.
Together, this would be a total of 299m+261j mg of calcium.
We want to meet or exceed 1000 mg of calcium. This means we could have more than 1000 or equal to 1000; this gives us the inequality symbol "greater than or equal to":
299m+261j ≥ 1000
