What is the distance between the points (2, 5) and (5, 9)?

A coyote can run up to 43 miles per hour while a rabbit can run up to 35 miles per hour.write two equivalent expression and then

yaroslaw [1]

D=s*t
distaance=speed times time

cd=coyote distance*time=ds*dt
rd=rabbit diatance*time=rs*rt

given
t=6 for all, so dt=rt=6

and ds=43
rs=35

cd=43*6=258miles
rd=35*6=210miles

how much more?
258-210=48

48 more miles

enrollment in the ski/snowboard club increased by 30% this year. there are now 182 students in the club. how many students were

eduard

Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now

now=182

percent means parts out of 100 so
130%=130/100=13/10

182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140

140 students last year

How do you model a decimal using a fraction

stiks02 [169]

Okie dokie,
When converting a decimal, you use the place the decimal is in...
Let's review the places: tenths, hundredths, thousandths, etc.
You look at the last number to determine what place you're using!
-------------------
Now here's an example for the tenths place:
.5
it's in the tenths place, right? so put it over that number (with no decimal) over a 10.
(mobile) 5/10 or $\frac{5}{10}$
Now, decide if you can simplify. You can! 5/10 simplifies down to 1/2.
$\frac{1}{2}$ is your answer!
--------
Example for the hundredths place:
.26
the last number is in the hundredths place, so put the number (without a decimal) over 100!
26/100 or $\frac{26}{100}$
You can simplify this!
13/50 is your answer!

Calculators can also come in handy!
Good luck!

Liono4ka [1.6K]

This is basically a simple problem to understand. The only thing that needs to be done is to divide the mass of the sun by the mass of mercury. It will give the required result.

Number of times the mass of sun is greater than
the mass of mercury = 21.3525×102921.3525×1029/<span>328.5×1021328.5×1021
= </span><span>7.1783629e+15

explain to a friend Grady wants to buy a basketball video game that cots $59.95 including tax. He has $45.50 in cash and a gift

Tomtit [17]

Well first you would, subtract the gift certificate amount from the video game. Then you would subtract his total cash from the cost of the video game. The equation would look something like this: 45.50 - (59.95 - 15.25). The answer to your problem is yes he would have enough.
