Part (b)
The scale 1 cm = 2 m means we'll multiply whatever the cm distance is by 2 to get the meter distance in real life.
The shed is 3 cm by 3 cm on paper. It corresponds to 6 meters by 6 meters in real life.
----------
The cement pad is 6 meters by 10 meters in real life because it's originally 3 cm across and 5 cm vertical. We double each dimension as done before, and replace "cm" with "m".
----------
The hot tub is a circle so we don't get an exact measurement here. But we can determine a good estimate. It appears it's 2 cm across and 2 cm vertical. So that corresponds to 4 meters by 4 meters
=========================================
Part (c)
On paper, the distance is 4.5 cm since we count out 4 full squares plus half a square when going a horizontal distance from the cement pad to the pool.
Therefore, the distance in real life is 9 meters
1 cm = 2 m
4.5*(1 cm) = 4.5*(2 m)
4.5 cm = 9 m
==========================================
Part (d)
The flowerbed on paper has sides of 4 cm and 6 cm. Use the pythagorean theorem to find the hypotenuse is approximately 7.21 cm.
Double each dimension, and replace the 'cm' with 'm'
The side lengths of the actual flowerbed is 8 meters, 12 meters, 14.42 meters. That last value being approximate.
Add up the values to get the perimeter: 8+12+14.42 = 34.42
Answer: perimeter = 34.42 meters (approximate)

6. A) 120 plus or minus 17. A) (0, 22.7)8. B) When there are 0 people, the max noise is 22.7 dB9. D) 8910. B) The player had 318 at bats and 80 hits.========================================================
Explanations:
6. Plug in x = 65 and evaluate. You should get y = 120.2 which is fairly close to 120, give or take a decibel or so. 7. The y intercept is the value of b in y = mx+b. In this case, b = 22.7 and the location of the y intercept is (0, b) = (0, 22.7)8. Plug in x = 0 and you should get y = 22.7, which is the y intercept mentioned earlier. It means that if x = 0 people show up, ie the stadium is empty, then the noise level is 22.7 dB. This is probably unrealistic as there's no people around to make noises, unless there are machinery or similar making sounds. 9. Form the proportion 147/526 = x/317. Solve for x to get roughly x = 88.591, which rounds to 89. If we have 89 in this cell, then the row relative frequencies will fairly be the same (ie each row is pretty much identical after we compute the row relative frequencies) and that leads to a likely case we don't have association. 10. The point (x,y) = (318, 80) means x = 318 and y = 80 pair up together. The variable x is the number of at bats, and y is the number of hits.Mrs. C loans Mr. R $50 000 to start his magic shop.

Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 miles south. What distance, to the nearest tenth of a mile, would he travel if he took a direct flight from Portland to Denver?
1153.5 miles
1575 miles
425 miles
818.2 miles
Answers
Answer:
1153.5 miles (first answer choice)
Step-by-step explanation:
'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise'). Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:
d = √(1000² + 575²) = 1153.5 miles (first answer choice)

The slope is 2. and the y-intercept is 12.
Answers
Answer:
slope is -2 and the y-intercept is 12
Step-by-step explanation:
a key thing to remember: x is always equal to 0 when finding the y-intercept.
so if you look at the table for where 0 is, you get the point (0,12) meaning the y-intercept is 12.
to find the slope use the equation: slope= change in y/change in x
you can use any two points to find this.
lets take the points of the x-intercept (6,0) and the y-intercept (0,12)

What is the solution of -17 = -2y + 13 – 8y?
Answers
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
y = 3
