For this case we have the following statement:
<em>"You have 2 meters of fabric and you cut 85% to make curtains, 50% of the rest to make the strips that hold it. How many centimeters of fabric were left?"</em>
So, we have:
2 meters ---------> 100%
x ----------------------> 85%
Where "x" represents the amount of fabric meters equivalent to 85%.
Thus, 1.7 meters of fabric were used to make curtains.
There are 0.3 meters of fabric left, of which half (50%) is used to make the strips that hold the curtain. That is to say:
Thus, 0.15 meters of fabric remain.
Thus, 15 cm of fabric remain
Answer;
15 cm
Answer:
a. 7 by 21
b. a(-12, 2), b(-12, -5), c(9, -5)
Step-by-step explanation:
AD is 3 times the length of AB. X can be the length of AB. Then 3x would be the length of AD. The perimeter is 56, which would also be 3x + x + 3x + x which is 8x. This gives us 8x = 56, meaning that x is 7, or the length of AB is 7. Because AD is 3 times the length of AB (which is 7), AD = 21. Therefore, the dimensions of the rectangle ABCD is 7 by 21.
Coordinates of A have to be 21 units away from D since AD = 21. It goes in the left direction, meaning that 21 is subtracted from 9 (since this is a horizontal edge involving x coordinates) while the y value remains the same. The result is (-12, 2). For coordinate B, it has to be 7 units away from A downwards since AB = 7. This means that you subtract 7 from 2 (involving only the y coordinates), resulting in (-12, -5). For coordinate C, it has to be 21 units from B since BC = AD = 21. Because C is right compared to B, you have to add 21 to -12 (involving only the x coordinate) resulting in (9, -5).
Answer:
A) CPCTC
Step-by-step explanation:
This part of the proof occurs right after two triangles are proven congruent. One could now conclude and establish that every part of each congruent triangle is congruent, which is what is most likely happening in this scenario.
2x + 8 = 44
2x = 36
x = 18
There are 18 boys, and 26 girls

Answer:
I am gonna take a guest and say <em>178</em> for number 3. And for number 4, the answer is <em>44.</em>
Step-by-step explanation:
For number 3, I added 76 and 102 which equals 178. For number 4, I put n+6+3n-10=180 because its a triangle. Do the math and you get n=44. Correct me if I am wrong; I tried my best.
