Answer:
$30
Step-by-step explanation:
Given that :
Amount earned for mowing = $45
Amount spent on music = $5
Amount earned for washing neighbor's car = $10
Amount saved = half or remaining amount
Amount of dollars Fred keeps =
Amount Fred keeps:
[(Amount earned - amount spent) / 2] + $10
[($45 - $5) / 2] +
($40 / 2) + $10
= $20 + $10
= $30
Answer:
See Below
Step-by-step explanation:
y = ![\frac{x-v}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-v%7D%7Bb%7D)
Isolate x
First step, multiply both sides by b to get rid of fraction
y(b) = x - v
+v +v
y(b) +v = x
Hope this helps!=)
Answer: 1. 144
2. a
3. 790.05
4. 1.5
5. lenght width and height 4/5 = 24
Step-by-step explanation:
From the measure of 40°, you can write
tan(40°) = 100/x, where x is the base from the building to the tower
⇒x=100/tan(40°) = 119,18 m
2) From the measure of 30°, you can write
tan(30°) = y / 119,18, where y is the height from the roof of Jill's building to the top of the tower.
Then, y = tan(30°) * 119,18 = 68,81 m
3) The height of Jill's building is 100 - 68,81 = 31,19 m
