Answer:
-4
Step-by-step explanation:
So like ur last problem do it in order left to right.
[8x7]+5x(-8)/(-4)
56+[5x(-8)/-4
56+(-40)/-4
16/-4=(-4)
Sorry if i did in wrong order.
The answer will be A because 3x=-3
X= -1
Answer:
B. 8.0 cubic inches
Step-by-step explanation:
You need to find 190% of the volume of a gumball which is a sphere.
To find 190% of a quantity, multiply the quantity by 1.9.
volume of sphere = (4/3)(pi)(r^3)
diameter = d = 2 in.
radius = r = (1/2)d = (1/2)(2 in.) = 1 in.
volume of sphere = (4/3)(3.14159)(1 in.)^3 = 4.189 in.^3
The volume of a gumball is 4.189 in.^3
Now we need 190% of that volume.
190% of volume of sphere = 1.9 * volume = 1.9 * 4.189 in.^3 = 7.959 in.^3
Rounded to the nearest tenth, the volume is
B. 8.0 cubic inches
The interval is the value (-∞,2)
We have given that,
f(x)=x-3
g(x)= - 0.5x
<h3 /><h3>What interval is the value of (f-g)(x) negative?</h3>
First, calculate the (f-g)(x)
Since f(x)=x-3
g(x)= - 0.5x
So, (f-g)(x) = x-3-(- 0.5x)
⇒(f-g)(x) = x-3+ 0.5x
⇒(f-g)(x)
=1.5x-3
Now we are supposed to find the interval for which (f-g)(x) is negative.
So, (f-g)(x) =1.5x-3 <0
⇒1.5x<3
Thus for (f-g)(x), negative x must be less than 2
Thus the interval is(-∞,2)
Hence option B is correct.

Answer:
B. The radius
Step-by-step explanation:
The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle so we need to know the radius for it
