Let’s go left to right and convert everything to decimals.
3.4848 is 3.4848
-3 19/20 is -3.95
-3.58 is -3.58
Sqrt (11) is about 3.3
362% is 3.62
Using this, you can easily put them in order
Answer:
Megan would save $19.90.
Step-by-step explanation:
49.75 divided by 0.40 is equal to 19.90.
60 divided by 4.
EXPLANATION:
If his grandfathers age is 3 more than whatever 4 times seans age is. we can do 63 - 3. which is 60.
Then you fond seans age. 60 divided by 4 is the equation to find seans age.
sry its a bad explanation but I hope the answer helps!
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.
(-x-14)^2 = x^2 +14x+14x+196
which turns into x^2+28x+196.
hope this helps
and give thanks
