The diameter of a planet at its equator is 2730 kilometers.

Mathematics

Answer:

If the first question is indicating that the diameter of mercury is 4.88x10^3 kilometers, then to put this in standard notation you would move the decimal point three places to the right, which gives you 4880 kilometers.

For the second question, you have to count how many places to the right the decimal place needs to be moved to have a number in the ones place. In this case, that number is 4. Scientific notation would be 1.96x10^(-4) meters. For any number where the value is less than one, the ten will be to a negative power.

A coffee shop spends $408 for an order of 17 cases of paper cups.

solong [7]

Answer:

Option C is correct

$528 will the total cost spends by coffee shop

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates.

As per the statement:

A coffee shop spends $408 for an order of 17 cases of paper cups.

Unit rate per cases = $\frac{408}{17} =\$24$

Now, if If the coffee shop adds 5 more cases of paper cups to the order

then,

total number of cases = 17 +5 = 22 cases

To find how much total cost coffee shop spends.

Total cost = unit rate $\times$ total number of cases

= $24 \times 22 = \$528$

Therefore, total costs coffee shop spends = $528

You wish to package a spherical globe inside a cubical box . The diameter of the globe is 30 centimeters . How much empty space

Aneli [31]

Answer:

<h2>The empty inside the box is 12,870 cubic centimeters, approximately.</h2>

Step-by-step explanation:

Givens

The diameter of the globe (sphere) is 30 centimeters,
The box must has dimensions 30x30.

We need to find each volume to subtract them.

$V_{box}=(30cm)^{3}= 27,000 \ cm^{3}$

$V_{sphere}=\frac{4}{3} \pi (15cm)^{3} \approx 14,130 \cm^{3}$

The difference betweem the box and the sphere is

$\Delta V=27,000 - 14,130 = 12,870 \ cm^{3}$

Therefore, the empty inside the box is 12,870 cubic centimeters, approximately.

A dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 meter per second, while the cat

LenKa [72]

Answer:

They'll meet after 200 meters , if they simultaneously start running towards each other.

Step-by-step explanation:

Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.

Dog: Distance =Speed x time: x=30t

Cat: Distance = 200-x

=24t

The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs

So they will meet after 3.7 seconds

To check:

Distance travelled by dog :x=30(3.7)

=111.11 meters

Distance travelled by cat: 24t=24(3.7)

=88.89 meters

Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89

=200 meters
