Step-by-step explanation:

The two triangles are similar so

BC=BC

AB=AB

AC=AC

1.)5z=20 (÷b.s by 5)

z=4

2.)8=2x+2

8-2=2x

6=2x (÷b.s by 2)

x=3

3.)3y-3=15

3y=15+3

3y=18. (÷ b.s by 3)

y=6

Container A holds x liters of water.
Container B holds 2391 liters of water more than container A, so container B holds x+2391 liters of water.
Container A and B hold 11875 liters of water altogether.

$x+x+2391=11875 \\
2x+2391=11875 \\
2x=11875-2391 \\
2x=9484 \\
x=\frac{9484}{2} \\
x=4742$

Container A holds 4742 liters of water.

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.

Please please help me please

MAVERICK [17]

Answer:

1st option is the answer

Step-by-step explanation:

blue line: slope is 1 and y-intercept is 1; therefore equation is y= x + 1

red line: slope is -1 and y-intercept is -3; therefore equation is y= -x - 3
