-4(x + 3) < = -2 - 2x
-4x - 12 < = -2 - 2x
-4x + 2x < = -2 + 12
-2x < = 10
x > = -5

the correct number line will have closed circle on -5 with shading to the right

Find the volume of a cone with a base diameter of 12 m and a height of 10 m.

dexar [7]

Answer:

=376.8 $m^{3}$

Step-by-step explanation:

V=n $r^{2}$ $\frac{h}{3}$ Where V is the volume , r is the radius and h is the perpendicular height .

r = $\frac{12}{2}$ m=6

h = 10m

n=3.14

v= 3.14 * 6*6 * $\frac{10}{3}$

=376.8 $m^{3}$

Y = -3x + b
Plug in point
-4 = -3(3) + b
-4 = -9 + b, b = 5
Solution: y = -3x + 5

Estimate the sum 8/10 + 1/9

RideAnS [48]

Answer:

41/45

Step by Step Explanation:

Add: 8/

+ 1/

= 8 · 9/

10 · 9

+ 1 · 10/

9 · 10

= 72/

+ 10/

= 72 + 10/

= 82/

= 2 · 41/

2 · 45

= 41/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 9) = 90. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 9 = 90. In the following intermediate step, cancel by a common factor of 2 gives 41/

In other words - eight tenths plus one ninth = forty-one forty-fifths.
