Answer:

x = 2.8 units

Step-by-step explanation:

volume = width x length x height

23.52 = 1.5 x 5.6 x height

height = 23.52/(1.5 x 5.6) = 23.52/8.4 = 2.8 units

The graph of a quadratic equation will always cross the x-axis, that’s false because only the y-axis can cross into in only one place.

You make a salary of $400 a month plus a 10% commission. If your total sales were $2000, how much money in total would you make

kykrilka [37]

Given:

Salary = $400 a month

Rate of commission = 10%

Total sales = $2000

To find:

The total money you will make this month.

Solution:

We have,

Rate of commission = 10%

Total sales = $2000

Commission = $2000\times \dfrac{10}{100}$

= $200$

We know that,

Total money = Salary + Commission

= $\$400+\$200$

= $\$600$

Therefore, the total money you will make this month is $600.

-2(x+1)+6x<-14<br>I need help

jeka57 [31]

Answer:

x<-3

Step-by-step explanation:

-2(x+1)+6x<-14

Distribute

-2x-2 + 6x < -14

Combine like terms

4x -2 < -14

Add 2 to each side

4x-2+2 < -14+2

4x < -12

Divide by 4

4x/4 < -12/4

x<-3

A runner runs around a circular track. He completes one lap at a time of t = 269 s at a constant speed of v = 4.6 m/s. What is t

AURORKA [14]

Answer:

$\boxed{\text{197 m}}$

Step-by-step explanation:

The formula relating distance (d), speed (s), and time (t) is

d = st

1. Calculate the distance

d = 269 s × 4.6 m·s⁻¹ = 1240 m

2.Calculate the track radius

The distance travelled is the circumference of a circle

$\begin{array}{rcl}C & = & 2 \pi r\\1240 & = & 2 \pi r\\\\r & = & \dfrac{1240}{2 \pi }\\\\& = & 197\\\end{array}\\\text{The radius of the track is }\boxed{\textbf{197 m}}$
