Answer:
Any coordinate point with (positive x, negative y)
No they do not have the same number of zeroes
Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600
both have 3 zeroes before multiplying
if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer
if we take 40 x 500 - 4 x 5 = 20
then theres an extra zero added
but if we take 40 x 600 - 4 x 6 = 24
no extra zeroes added to this
so if we finally look at the answers
40 x 500 = 20 000
40 x 600 = 24 000
20000 has 4 zeroes and 24000 has 3 zeroes
so the answer is no they dont have the same number of zeroes
Answer:
The first option (5.7km)
Step-by-step explanation:
Since we have a right angle triangle and we know two of its sides we can easily find out the thirds side (the value of d) by using the Pathagoras Theorem. In our case 7 and d are our legs and the hypotenuse is equal to 9, so...
(Based on the Pathagoras Theorem)
d ≈ 5.7km
There for aproximate distance across the lake is equal to 5.7km
Answer:
4. D
5. A
Step-by-step explanation:
For #4, I first divided 15 by 4 and saw what the greatest whole number it was divisiable by. Then I wrote the remain as a fraction
For #5, I first multiplied by 4*6 and then add 5 to that answer
For number 15 and 16, you just have to find the absolute difference between the two points along the calibration of the protractor.
15. ∠BXC = |B - C| = |140° - 110°| = 30°
16. ∠BXE = |B - E| = |140° - 30°| = 110°
For numbers 20 and 21, apply the Angle Addition Postulate. This is when you add the individual interior angles to equate to the total angle.
20. ∠PQS = ∠PQR + ∠RQS
112° = 72°+ 10x°
x = 4
21. ∠KLM = ∠KLN + ∠NLM
135° = 47°+ 16y°
y = 5.5
