cara works at a fine jewelry store and earns a commission on her total sales for the week. her weekly paycheck was in the amount

Gekata [30.6K]

Cara's rate of commission is 12%.

Step-by-step explanation:

Given,

Paycheck = $6500

Salary = $1000

Commission = Paycheck - Salary

Commission = 6500-1000 = $5500

Total sales for the week = $45000

Commission rate = $\frac{Commission}{Total\ Sales}*100$

$Commission\ rate=\frac{5500}{45000}*100\\\\Commission\ rate=\frac{550000}{45000}\\\\ Commission\ rate=12.22\%$

Rounding off to nearest whole number.

Commission rate = 12%

Cara's rate of commission is 12%.

Slope of the line that passes through (3, -11) and (0, 4), please!

Lorico [155]

Answer:

-5

Step-by-step explanation:

slope formula= $\frac{y1 - y2}{x1 - x2}$

slope of line

$= \frac{4 - ( - 11)}{0 - 3} \\ = \frac{4 + 11}{ - 3} \\ = \frac{15}{ - 3} \\ = - 5$

A cyclist rides his bike at a rate of 15 miles per hour. what is this rate in miles per minute? how many miles will the cyclist

ryzh [129]

Answer:

15 miles/hour = 0.25 miles/minute

The cyclist would have traveled 5 miles in 20 minutes.

Step-by-step explanation:

15 miles per hour is written as

15 miles/hour

To convert 15 miles/hour to miles/minute

From 1 hour = 60 minutes

∴ 15 miles/hour = 15 miles/ 60 minutes

= (15/60) miles/minute

= 0.25 miles/minute

To calculate how many miles the cyclist will travel in 20 minutes

That is, Time, t = 20 minutes

Velocity, v = 15 miles/hour = 0.25 miles/minute

Distance, s = ??

From,

$Velocity = \frac{Distance}{Time}\\$

∴ $Distance = Velocity$ × $Time$

$Distance = 0.25 miles/minute$ × $20 minutes$

$Distance = 5 miles$

Hence, The cyclist would have traveled 5 miles in 20 minutes.

A hot-air balloon is 140 ft140 ft above the ground when a motorcycle (traveling in a straight line on a horizontal road) pass

luda_lava [24]

Answer:

Step-by-step explanation:

Given

Balloon velocity is 14 ft/s upwards

Distance between balloon and cyclist is 140 ft

Velocity of motor cycle is 88 ft/s

After 10 sec

motorcyclist traveled a distance of $d_c=88\times 10=880 ft$

Distance traveled by balloon in 10 s

$d_b=14\times 10=140 ft$

net height of balloon from ground =140+140=280 ft[/tex]

at $t=10 s$

distance between cyclist and balloon is $z=\sqrt{280^2+880^2}$

$z=923.47 ft$

now suppose at any time t motorcyclist cover a distance of x m and balloon is at a height of h m

thus $z^2=(88t)^2+(14t+140)^2$

differentiating w.r.t time

$\Rightarrow z\frac{\mathrm{d} z}{\mathrm{d} t}=14\cdot \left ( 14t+140\right )+88\cdot \left ( 88t\right )$

$\Rightarrow at\ t=10 s$

$\Rightarrow \frac{\mathrm{d} z}{\mathrm{d} t}=\frac{14\cdot \left ( 14t+140\right )+88\cdot \left ( 88t\right )}{z}$

$\Rightarrow \frac{\mathrm{d} z}{\mathrm{d} t}=\frac{14\times 280+88^2\times 10}{923.471}$

$\Rightarrow \frac{\mathrm{d} z}{\mathrm{d} t}=\frac{81,360}{923.471}=88.102\ ft/s$
