Answer: 3+7+9=19.....7/19=0.368 percent. Move the decimal two places to the right and round up for 37%
Step-by-step explanation:
Add all the colors together to get a TOTAL amount of ALL marbles.
The total amount for this problem is 19 (3+7+9=19)
The blue amount of marbles is given as 7.
Divide the blue amount (7) by the total amount (19) for the specific percentage for that color.
Answer:
The answer is 12
Step-by-step explanation:
3√16, Rewrite 16 as 4 with an exponent of 2. Pull terms out from under the radical, assuming positive real numbers: 3⋅4. Then Multiply 3 by 4: 12. So the answer is 12
The perimeter is 39.8
So, the first step to this is looking for any tick marks on the triangles sides.
These ticks represent equal. We can see there are marks between A-B and A-D.
Those are there to represent that line AB and line AD are equal. Since we are given that line AB is 12.1cm, we can say line AD is also 12.1 cm.
From there we can take a look at line AC. We can see that these two triangles share a side.
Also the two angle marks are like tick marks. They represent equal. So we can also say angle DAC is equal to angle BAC.
Now we have enough information to conclude that these triangles are are the same. (They are equal to each other).
Now that it is clear they are equal, we know that Line DC (7.8cm) is the same length as line BC because they are the same triangles with the same length sides. So line BC is also 7.8.
Now let's add up all the sides. Remember do not include line AB (the 10cm.) Perimeter is only the outside of the shape.
12.1+12.1+7.8+7.8=39.8
Hope this helped!
