Answer:

y ≥ 3x +4

Step-by-step explanation:

The line is solid, so the inequality will include the "or equal to" case. The shading is above the line, so values of y greater than or equal to those on the line are in the solution set. The only choice with the correct (≥) inequality symbol is ...

y ≥ 3x +4

A right rectangle prism is 6 cm by 14 cm by 5 cm what is the surface area of the right prism

NeX [460]

Answer:

$\large\boxed{S.A.=368\ cm^2}$

Step-by-step explanation:

The formula of a surface area of a rectagular prism:

$S.A.=2(lw+lh+wh)$

l - length

w - width

h - height

We have the dimensions 6cm × 14cm × 5cm. Substitute:

$S.A.=2(6\cdot14+6\cdot5+14\cdot5)=2(84+30+70)=2(184)=368\ cm^2$

A jet travels from chicago to kansas city at a speed of 440 knots. If it takes a plane 3 hr longer to fly from kansas city to ch

steposvetlana [31]

d = distance between the two cities

v₁ = average speed while going from chicago to kansas city = 440 knots

t₁ = time taken to travel distance going from chicago to kansas city

time taken to travel distance going from chicago to kansas city is given as

t₁ = d/v₁

t₁ = d/440 eq-1

v₂ = average speed while going from kansas city to chicago = 110 knots

t₂ = time taken to travel distance going from kansas city to chicago

time taken to travel distance going from kansas city to chicago is given as

t₂ = d/v₂

t₂ = d/110 eq-2

Given that :

t₂ = t₁ + 3

using eq-1 and eq-2

(d/110) = (d/440) + 3

d = 440

a high school stage collapsed in Fullerton, California, when 250 students got on stage for the finale of a musical production. T

Lera25 [3.4K]

Answer:

Step-by-step explanation:

In this question, the important information we get from this is that the stage can support 12,750 students. We are asked, if the average weight of a student is 140 pounds, what is the maximum number of students that can be on the stage safely?

To solve, we simply divide 12,750 by 140.

$x=\frac{12,750}{140}$

$x= 91.07$

We get 91.07 as our answer. Since we are considering the maximum number of students, then we must round 91.07 to the nearest whole number which would be 91.

The maximum number of students who could safely be on the stage is 91.
