Answer:
255
Step-by-step explanation:
We need to find 75% of 340...
75%*340
Let's convert 75% to a fraction to make the math easier...
75/100*340
Now let's simplify 75/100 to again make it easier...
3/4*340=255
<u>Step-by-step explanation:</u>
We are asked to draw a triangle.
The information we are given with is AB is a line segment with length 3.9 cm.
∠CAB = 50°.
∠ABC = 63°.
With the given details we need to draw triangle using given angles. We need protractor and ruler to draw the triangle.
Step 1: Draw the line segment of length 3.9 cm using ruler and mark as AB.
Step 2: Using protractor, we need to mark the angle. Keep the center of the protractor at the A and mark with a point at 50°.
Step 3: Draw a line from a passing through the marked point.
Step 4: Repeat step 2 with marking at 63° and step 3 on the other side.
Step 5: Mark the intersection point as C.
Step One
Begin by drawing a line parallel to the x axis. Create it so it goes through (0,1)
This line you have drawn should hit points on the figure at (-5,1) (-2,1) and (3,1)
You now have a figure on the bottom that is a trapezoid. It has 2 small triangles on top of it. We'll talk about them later.
Step Two
Find the area of the trapezoid.
<em>Formula</em>
Area = (b1 + b2)*h/2
h = 1 - - 3 = 4
b1 = 3 - - 8 = 11
b2 = 3 - - 5 = 8
Area = (11 + 8)*4 / 2
Area = (19 ) * 2
Area = 38
Step Three
Find the area of the small triangle on the left.
The base goes from -5 to - 2 which is 3 units.
The height goes from 1 to 3 (using the y axis as a reference) which is 2
Area = 1/2 * b * h
Area = 1/2 *3 * 2
Area = 3
Step Four
Find the area of the small triangle on the right.
The base is 5 (see if you can get 5 as an answer)
The height is 1.
Area = 1/2 b * h
Area = 1/2 5 * 1
Area = 2.5
Step Five
Total Area is found by adding the three areas together.
Total Area = trapezoid + small triangle on the left + small triangle on the right
Total Area = 38 + 3 + 2.5 = 43.5
43.5 <<<< answer
A. All of the members of the PTA.
Answer:
First, 24 divided by 8 equals 3. this means you divide 12 by 3. you get 4. 4 cups of sugar will be used when 8 cups of flour are used.
