Mario walked at a rate of mile every minutes.
What was his walking rate in miles per hour?
Answer: 4mi/h
Step-by-step explanation:
We have that Mario walks 2/3 of a mile every 10 minutes. Representing this as a fraction:
[tex]\frac{2/3}{10} \frac{mile}{minute}[/tex]
Next, you can use something called "dimensional analysis." A dimenision in this case would be the units. The desired units we want are miles per hour, but we are given miles per minute. You can use a few conversion factors to help get to those desired units. In 60 minutes, there is 1 hour. Let's multiply this conversion factor by our original fraction:
[tex]\frac{2/3}{10} \frac{miles}{minute}*\frac{60}{1} \frac{minute}{hour}[/tex]
As you can see above, the units of minutes will cancel. This will leave the units of miles on top, and hours on the bottom. Our units are now miles per hour after simplifying things:
[tex]\frac{2/3}{10}\frac{60}{1} \frac{miles}{hour}=2/3*6 \frac{miles}{hour}=4\frac{miles}{hour}[/tex]

A triangle with vertices A(2, -2), B(-1, -1) and C(0, 2) is reflected across the y-axis and then dilated by a factor of 3 with the origin as the center of dilation.
What is the x-coordinate of the A''?
-2
2
-6
-4
Answer:C-6
Step-by-step explanation:(2,-2) reflected over X would be (-2,2). Then dilate by 3 which you multiply by 3. So -2 x 3 = -6.

Answer:
3/10 is greater. and the bottom part is 30
Step-by-step explanation:
because 1/6= 0.2 and 3/10=0.3.
0.2>0.3 therefore 3/10 is greater.
and to find the common denominator you just have to list out the number of and 10.
6,12,18,24,30
10,20,30
as you can see 30 is the common denominator.

A triangle has one side that is 4 centimeters long and one that is 9 centimeters long. The third side is a whole number of centimeters. What is the longest possible third side?
Answer:
12 cm
Step-by-step explanation:
You want the longest possible integer length of the third side of a triangle with sides 4 cm and 9 cm.
Triangle inequalityThe triangle inequality requires the longest side be less than the sum of the other two sides:
x < 9 cm + 4 cm
x < 13 cm
The largest integer length less than 13 cm is 12 cm.
The longest possible third side is 12 cm.

Rebecca had these results when she drew 10 tiles from the bag. The bag has a total of 20 tiles. Her classmates got similar results. What is a good predication for the number of green and red tiles out of 20?
Answer:
10/20
Step-by-step explanation:
if she has 20 in total and there's only two colours I would assume it's an even chance,
For example a coin has two sides, = even chance of getting each side.
Good luck hope this helped
What are the first two steps of drawing a triangle that has all side lengths equal to 12 centimeters?
Select from the drop-down menus to correctly complete the statements.
Draw a segment (6, 12, 24) centimeters long. Then from one endpoint, draw a (30, 60, 90) ° angle.
Answer:
All the sides should be 4 cm.
Step-by-step explanation:
The first triangle rule is the two sides should be greater than the longest side when added together.
For example- 4+4=8 which is bigger than 4
12 divided by 3 is 4.
Hope this helps.
Answer:
Step-by-step explanation:
Remark
All triangles have 180 degrees.
In order that all sides be 12cm long, you need to draw a base line that goes on for more than 12 cm.
Mark off the (using a ruler) a line that is 12 cm from one of the line written about.
From that same endpoint, draw an angle that is 60o. Draw a line going 60 degrees from your first line.
=============
Just to finish the triangle, go to the other end of the 12 cm line. Draw another 60 degree angle. Make it so that it will intersect the second line you drew.\

A grocer combined peanuts that cost $5.20/lb with walnuts that cost $6.40/lb. How many pounds of each were used to make a 45 pound mixture that cost $6/lb?
Answer:
Step-by-step explanation:
Factor the expression using the GCF.
4m+32
In order to factor this expression, we should divide both terms of this binomial (a polynomial with 2 terms) by 4 (the greatest common factor)
Note:- We usually factor out the Greatest Common Factor, or the GCF.
Divide:-
m
8
Add the terms:-
m+8
Put parentheses around them:-
(m+8)
Put 4 outside the parentheses:-
4(m+8)
notes:-If you wonder whether or not you've factored correctly, you can use the distributive property & distribute :)
What is the area of the circle?
12.56 square inches
6.28 square inches
25.12 square inches
3.14 square inches
Answer:
D. 3.14
Step-by-step explanation:
A = πr^2
2/2=1
r=1
1 squared is 1
so, 1 X Pie = 3.14
Identify Structure Each figure below is made up of congruent trapezoids. Find the area of each figure.
Answer:
12cm
Step-by-step explanation:
The formula to find the area of a trapezoid is A = [tex]\frac{a + b}{2}[/tex]h. We replace the "a" and "b" with 6cm. We then replace the "h" with 12cm as your height is 12cm. The new formula is A = [tex]\frac{a + b}{2}[/tex]h = [tex]\frac{6 + 6}{2}[/tex] x 12. The answer to that equation is 12cm.

Jaylah started with $200 in her savings account to go to Disneyland. She wanted to increase her savings so she started babysitting. She earns $10 an hour and deposits it in her savings account. What is Jaylah's initial value and rate of change?
Answer:
Initial Value= $200, Rate of Change= $10 per hour (or just $10)
Step-by-step explanation:
The initial value is what Jaylah started with, and in this case, she starts with $200.
The rate of change is how much Jaylah earns, in this case per hour. It says that she earns $10 an hour, so the rate of change is $10.
Angle math Hw. Pls help
Answer:
x = 45°
Step-by-step explanation:
We can tell that "x + 115" and 160° are vertically opposite angles, which means that they are equal. (Refer to image)
⇒ x + 115 = 160
⇒ x = 160 - 115
⇒ x = 45°

Image:The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000 . What is the difference in the populations of the cities when t=4 ?
Answer:
The difference in the populations of the cities when t=4 is 25,800.
Step-by-step explanation:
Given equations each of the city:
-150t+50,000
and
50t+75,000
To find the difference between the population when t=4, we first have to solve both equation when t=4.
For both equations, substitute 4 into t:
-150(4) + 50,000 = 49,400
50(4) + 75,000 = 75,200
Now subtract 49,400 from 75,200 and you get 25,800.
The difference in the populations of the cities when t=4 is 25,800.

5) The graph is going up by 500's and this could be misleading because you would have to estimate the elevation.
Step-by-step explanation:
Answer:
it depends
Step-by-step explanation:
for 4 you could say mountain a is 2,250 feet higher or that it is x% higher.
for 5 you could put "the graph may be misleading because the graph starts at a non-0 number thus making one mountain seem much taller than the other" because both mountains start at 16,500 and not 0 making the difference seem more extreme than it is.
