Answer:
29.) -14
45.) B
46.) D
The one after that.) C
Step-by-step explanation:
29.
3x-4=4x+10
3x-4x=10+4
-x=14
x=-14
45.
B because it says that the value of c or the number of cars cannot be greater than 5000, so it has to be 0 to 5000
46.
D because it doesn't set a limit on haw many days you can stay, rather it just talks about the the equation for payment.
The One After That.
C because the only time that the graph is decreasing is the time when there is a negative slope. That negative slope is only present in the interval given for answer C.
Pi = 3.141593
Radius = half diameter
Calculate Circumference = 2 pi r (2*pi*radius)
Calculate Time = Circumference / Speed
Angles three and four are a linear pair, meaning that they they form a line. When two angles make a line, the measures add up to 180°. Adding the two values together, we see that 3x+27x=180. Simplifying and solving for x, we get 30x=180 ⇒ x=6.
The question, however, is asking for the measure of angle 4. Thus, we plug x=6 into 7x to get 6(7)=42.
Hope this helped!
Answer:
C) 3057.6 cm³
Step-by-step explanation:
Rectangular prism: 20x11x9=1980
Cylinder: r²h = X7x7x7=1077.57
1980+1077.57=3057.57
