Martin can run 1 mile in 7 minutes. What proportions can be written from this information?

jeka57 [31]

Answer:

$\frac{1}{7}=\frac{3}{21}$

$\frac{7}{1}=\frac{21}{3}$

Step-by-step explanation:

Verify each case

case 1) $\frac{1}{7}=\frac{3}{21}$

Multiply in cross and then compare both sides

$1*21=7*3$

$21=21$ ----> is true

therefore

Is a valid proportion

case 2) $\frac{1}{21}=\frac{3}{7}$

Multiply in cross and then compare both sides

$7*1=21*3$

$7=63$ ----> is not true

therefore

Is not a valid proportion

case 3) $\frac{7}{1}=\frac{3}{21}$

Multiply in cross and then compare both sides

$21*7=1*3$

$147=3$ ----> is not true

therefore

Is not a valid proportion

case 4) $\frac{7}{1}=\frac{21}{3}$

Multiply in cross and then compare both sides

$3*7=1*21$

$21=21$ ----> is true

therefore

Is a valid proportion

case 5) $\frac{1}{7}=\frac{21}{3}$

Multiply in cross and then compare both sides

$3*1=7*21$

$3=147$ ----> is not true

therefore

Is not a valid proportion

Please help me with this

umka21 [38]

Answer:

Step-by-step explanation:

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode. Therefore if you look at the chart you can see that one more people get 8 than 9, 10, or 5.

Hope this helps

Please inform me if I have made a mistake, I enjoy learning from my mistakes:)

Answer:

Distance between cities Y and Z = 26 miles

Step-by-step explanation:

From the picture attached,

Length of XY = 10 mi

Length of XZ = 24 mi

By applying Pythagoras theorem in the given right triangle XYZ,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

YZ² = XY² + XZ²

= 10² + 24²

= 100 + 576

= 676

YZ = √676

= 26 mi

Therefore, distance between cities Y and Z is 26 mi.
