Answer: The answer is x = 65 - 60y.
Step-by-step explanation: Given that Miguel is the grandfather of Raul and Paula is Raul's sister.
Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).
Also, given is the following information -
Raul's age = Grandfather's age - 60 × sister's age.
Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age
Thus, we can find Paula's age (y) using the equation
where 'x' is the age of Raul.
check the picture below.
so, when we have a line from a 90° angle running perpendicular to the opposite side, like in this case, we end up with three similar triangles, a large one containing the other two, a medium and a small one.
now, using the sides proportions as you see there, of the small and large one, we get that much.
17) The line that is John is closer to certain but not exactly on certain so I'd say it's "likely"
18) Using that same example as the one above, if 0 means impossible, then 1 means certain. I'd place your label for Sara at 1.
19) Let s = sides of the square. There are 4 sides and all sides are equal so we can set up the equation 4s = 64. Divide both sides by 4. s = 16. Now add 2 to this. 16 + 2 = 18. The length of each side of the original square was 18.
20) If the scale is 1 cm : 1 meter and the height of the model is 16 cm, then the actual plane must be 16 meters.
21) 2x and 100 are supplementary angles meaning together they must add up to 180.
2x + 100 = 180
2x = 180 - 100
2x = 80
Divide both sides by 2
x = 40
22) Assuming 3x is supposed to be the right angle, right angles are 90 degrees.
3x = 90
Divide by 3 on both sides
x = 30.
*The missing image is attached with the answer*
The correct answer is:
Height = h =5 unitsExplanation:a = 6 = Smaller base
b = 10 = Larger base
h = height
Area = A = (a + b)h/2 = 40
Plug in the values in the above equation:
h = (2*40)/(6+10)
h = 5 units
It would take 100 small beetles to equal the mass of one small brick.
