Answer:

Let u be 1 unit.

6u = 60.5kg

u = 60.5kg ÷ 6

= 121/12kg

=10/1/12kg

Hence, his mass on the moon is 10/1/12kg.

A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second. 1 m = 10 dm 1000 m = 1 km How mu

insens350 [35]

The sea turtle's speed is
$v_{t} = (27 \, \frac{km}{h} )*(1000 \, \frac{m}{km} )*( \frac{1}{60} \, \frac{h}{min} ) = 450 \, \frac{m}{min}$

The girl's speed is
$v_{g} = (14 \, \frac{dm}{s} )*( \frac{1}{10} \, \frac{m}{dm} )*(60 \, \frac{s}{min} ) = 84 \, \frac{m}{min}$

The ratio of the turtle's speed to that of the girl is
$\frac{v_{t}}{v_{g}} = \frac{450}{84} =5.357$

Answer: 5.36 faster (nearest hundredth)

Answer:

angle Z=20°

side xy≈15.36

hypotenuse≈19.49

Step-by-step explanation:

Find angle z adding the other two angles and subtracting that by 180 to get 20.

(12)tan(20) gets you side xy which is 15.36

12^2+15.36^2=xz^2

3. Haley, Chuck, Dana, and Chris enter a contest to see who could bake the most chocolate chip cookies in an hour. Haley bakes 5

otez555 [7]

Chris baked 95 cookies.

Step-by-step explanation:

Given,

Cookies baked by Haley = 50

Cookies baked by Chuck = 65

Cookies baked by Dana = 90

Average of them = 75

Let,

Cookies baked by Chris = x

Average = $\frac{Sum\ of\ quantites}{No.\ of\ people}$

$75=\frac{50+65+90+x}{4}$

Multiplying both sides by 4

$4*75=\frac{50+65+90+x}{4}*4\\300=205+x\\300-205=x\\95=x\\x=95$

Chris baked 95 cookies.

A rectangular skate park is 60 yards long and 50 yards wide

lawyer [7]

It is unclear what you want to do, but in the case where they give you the length and the width, it is most likely they are asking for either area or perimeter. For Area, it is length times width.
A = l x w
A = 60 yards x 50 yards
A = 3000 square yards.
For Perimeter of the rectangle, it is 2 of the lengths plus 2 of the widths.
P = 2 ( 60 yards ) + 2 ( 50 yards )
P = 120 yards + 100 yards
P = 220 yards
I hope this helps :-)
