HELP. ASAP. EASY MUTIPLE CHOICE QUESTIONS.<br>

Alina [70]

Answer:

C 44.59

Step-by-step explanation:

The first two shirts are full price

2*49.96 = 99.92

The third shirt is 50% off. That means it is 50% of the original price

.5*49.96 = 24.98

The total cost before tax is

99.92+24.98 =124.90

tax = cost * tax rate

tax = 124.90*.071

tax=8.87

Add this to the cost

final cost = 124.90+8.87

=133.77

We want to find the mean cost (average cost)

Take the total cost and divide by the number of shirts

133.77/3 =44.59

Help? (i mark brainlist)

Bad White [126]

Answer:

Step-by-step explanation:

Since it says greater than, that means that it cannot be B or D. And ≥ means greater than or equal to and they don't state that in the problem. So the answer would be A.

What is the slope of the line?

Umnica [9.8K]

Answer:

$\frac{2}{1}$

Step-by-step explanation:

Hello!

To find the slope of a line we divide how many times it goes over by the number of times it goes up

The line goes over 4 and up 2 which is shown like

$\frac{4}{2}$

We can simplify this

$\frac{2}{1}$

The answer is $\frac{2}{1}$

Hope this helps!

The 1992 world speed record for a bicycle (human-powered vehicle) was set by Chris Huber. His time through the measured 200 m st

Reil [10]

Answer:

a) 30.726m/s and b) 5.5549s

Step-by-step explanation:

a.) What was Chris Huber’s speed in meters per second(m/s)?

Given the distance and time, the formula to obtain the speed is

$v=\frac{d}{t}$ .

Applying this to our problem we have that

$v=\frac{200m}{6.509s}= 30.726m/s$ .

So, Chris Huber’s speed in meters per second(m/s) was 30.726m/s.

b) What was Whittingham’s time through the 200 m?

In a) we stated that $v=\frac{d}{t}$ . This formula implies that

$t=\frac{d}{v}$ .

First, observer that $19\frac{km}{h} =19,000\frac{m}{h}=\frac{19,000}{3,600}m/s= 5.2777m/s$ .

Then, Sam Whittingham speed was equal to Chris Huber’s speed plus 5.2777 m/s. So, $v=30.726\frac{m}{s} +5.2777\frac{m}{s}= 36.003 m/s.$

Then, applying 1) we have that

$t=\frac{200m}{36.003m/s}=5.5549s.$

So, Sam Whittingham’s time through the 200 m was 5.5549s.
