What is the scale on the map?
The scale on the map is 1 cm for 500 m.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
Given that, A man walks 1500 metres. on a map, this is shown as 3 cm.
3 cm = 1500 m
1 cm = 500 m
Hence, The scale on the map is 1 cm for 500 m.

Gerard tales 30 minutes to run 6000 metres at a steady speed. How long would he take to run 1 kilometre at the same steady speed
Answer: He would take 0.0833 hour or 5 mins
Step-by-step explanation:
Given that Gerard ran a 6000 metres in 30 minutes, Speed becomes
Speed =distance / time
But time to hours becomes 30/ 60=1/2=0.5hr
and meters to kilometres becomes 6000/1000=6 km
Speed =6/0.5 =12 km/h
Now if he runs 1 kilometre at same speed of 12 km/h . he will take
Time =distance/ Speed
Time =1/12=0.0833 hour Changing to mins becomes 0.08333 x 60=5 mins

Three people are coloring the same piece of 8 1/2 by 14 paper. Abby starts on the left side and painted 1/2 of the paper red. Ben starts on the right side and painted 3/4 of the entire paper green. Cathy starts in the middleand painted 1/3 of the entire paper, evenly on either side of the centre line, using blue color. What fraction of the paper has all three color painted on it?
Answer:
12/6
Step-by-step explanation:
The cone and the sphere have the same volume. The diameter of the cone is 24 cm, and the diameter of the sphere is 18 cm.
What is the HEIGHT of the CONE? Use 3.14
2) Mass of the earth is 5976000000000000000000000 kg and that of Uranus is 86800000000000000000000000 kg , which one has greater mass ? and how much ? compare in exponential form.
Step-by-step explanation:
mass of earth=5.976×10^24 and
mass of Uranus =8.68×10^25
the mass of
Uranus is greater than that of the Earth by comparing its power 10
The mass of Uranus is greater than that of the Earth by comparing its power 10
What is an exponential form of 10?It is a shortcut way of writing repeated multiplication involving base and exponents. For example the 3 in [tex]10^{3}[/tex] is called the exponent. The expression [tex]10^{3}[/tex] is called exponential expression.
Given
Mass of the earth = 5976000000000000000000000 kg
Rewrite in exponential form
Mass of the earth = 5.976×10^24
Mass of Uranus = 86800000000000000000000000 kg
Rewrite in exponential form
Mass of the Uranus = 8.68×10^25
∴ 8.68 × [tex]10^{25}[/tex] > 5.976 × [tex]10^{24}[/tex]
We can clearly say that by seeing the exponential form of masses of earth and Uranus i.e.,
The mass of Uranus is greater than that of the Earth by comparing its power 10.

Phillip watched a beach vollyball game from 1 p.M. To 1:15 p.M How many degrees did the minute hand turn?
Answer: 90°
Step-by-step explanation:
A full rotation on a clock would be 360° like a normal circle and this would represent a full hour.
When it comes to 15 minutes therefore, to find the number of degrees the time would turn, find out the proportion of an hour that 15 minutes is then relate it to 360°.
= 15 mins / 60 mins
= 1/4 hours
If an hour is 360°, 1/4 hours must be:
= 1/4 * 360
= 90°

Which is the better buy? 16 cards for $12.20 OR 14 cards for $10.90
Answer:
The better buy is 16 cards for $12.20 because
Step-by-step explanation:
You need to find the individual price for each card in the packet. So first lets do 16 cards for $12.20, you divide $12.20 by 16 to get the price of one card. 12.2/16=0.7625, or about $0.76. Next we do $10.90 divided by 14, 10.9/14=0.7785, or about $0.78, which means 16 cards for $12.20 is the better buy!
Today's cafeteria specials at a high school in Westford are a deluxe turkey sandwich and a chef salad. During early lunch, the cafeteria sold 13 turkey sandwiches and 69 chef salads, for a total of $151. During the late lunch, 61 turkey sandwiches and 41 chef salads were sold, for a total of $143. How much does each item cost?
Answer:
chef salads = $2
turkey sandwiches = $1
Step-by-step explanation:
two equations can be derived from the question
13t + 69c = 151 eqn 1
61t + 41c = 143 eqn 2
t = turkey sandwiches
c = chef salads
multiply equation 1 by 61 and equation 2 by 13
793t + 4209c = 9211 eqn 3
793t + 533c = 1859 eqn 4
subtract equation 4 from 3
7352 = 3676c
c =2
substitute for c in equation 1
13t + 69(2) = 151
13t + 138 = 151
13t = 151 - 138
13t = 13
t = 1
Write the slope intercept form of the equation for a line passing through (-3,-1) and
(0,4)
Answer:
y = 5/3x + 4
Step-by-step explanation:
First, you need to find the slope. Use the slope formula of (y^2-y^1) / (x^2 - x^1).
Plug the numbers in.
(4 - (-1)) / (0 - (-3))
5 / 3
Slope is 5/3
Now, you have an equation of y = 5/3x + b.
Since one of the points shows you what y equals when x=0, that is your y intercept.

A sports company wants to package a ball with a 1.5-inch radius in sets of two. They have two options: a cylinder or a square prism.The company wants to use the package that has the least amount of wasted space. The company should choose
Answer:
The Company should choose to get the cylinder packages ( V = 42.39 in³ )
Step-by-step explanation:
The volume of a cylinder of radius of circumference 1.5 in and h = 1.5*4
h = 6 in is:
V(c) = π *r²*h = π * (1.5)²*6 = π *2.25*6
V(c) = 42.39 in³
Now V(p) = Square of the base ( of side 3 in) * h
h = 6 in
V(p) = (3)²*6
V(p) = 54 in³
If we compare these two volumes we see that the volume of the cylinder is small than that of the square prism

Determine the equation of the circle graphed below.
Answer:
Step-by-step explanation:
the formula for a circle not on the origin is :
(x−h)^2+(y−k)^2=r^2
for the circle shown it looks like the circle is centered at (1,3)
then h=1 and k=3 and the radius looks to be about 2
(x−1)^2+(y−3)^2=2^2
(x−1)^2+(y−3)^2=4
there is your equation for that circle shown in the graph

0.326 as a fraction
Answer:
163/500
Step-by-step explanation:
we will not only clearly explain how to get the answer to 0.326 as a fraction, but also prove to you that our answer is correct.
First, note that 1000 multiplied by .326 will get rid of the decimal point. Therefore, make a fraction where the numerator is .326 times 1000 and denominator is 1000 like this:
.326 x 1000
1000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
326
1000
The greatest common factor of 326 and 1000 is 2, which means you can divide the numerator and denominator by 2 and keep the same value:
326 ÷ 2
1000 ÷ 2
And when calculating the numerator and denominator in our fraction above, we get .326 as a fraction in the simplest form possible:
.326 =
163
500
