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]

this is the answer
Look at the screenshot
Answer:
A: 1.5
B: A = n/1.5
C: This means every bowl you make, you would need 1.5 pounds of clay.
Step-by-step explanation:
A: The constant of proportionality is otherwise known as the slope. The formula for the slope is [tex]y_{2}[/tex]-[tex]y_{1}[/tex] / [tex]x_{2}[/tex]-[tex]x_{1}[/tex] (rise over run.) Lets plug the values in.
4.5-0 = 4.5
3-0 = 3
4.5/3 =1.5
B:
A = n/1.5
C:
The point (1,1.5) is representing the x value, the number of bowls, and the y value, the amount of clay in pounds.
This means every bowl you make, you would need 1.5 pounds of clay.

Part 1
Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation p= -0.5x²+25x-111 models the profit of the fundraiser. What's the smallest amount, in dollars, that you can charge and make a profit of at least $114?
Answer:
12
Step-by-step explanation:
if we know we want a profit of at least 114, we need to solve for x.
if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.
-0.5(12)^2 + 25(12)-111 = 117
Subtract the rational expression

Solve [tex]\frac{-72}{x} = 9[/tex] using the distributive property.
Answer:
The answer is
→ [tex]x=-8[/tex]
Step-by-step explanation:
Given: [tex]\frac{-72}{x} = 9[/tex]
Solve:[tex]\frac{-72}{x} = 9[/tex]
Step 1: Multiply all terms by the same value to eliminate fraction denominators.
[tex]\frac{-72}{x} = 9[/tex]
⇒ [tex]x * \frac{-72}{x} = x * 9[/tex]
Step 2: Cancel multiplied terms that are in the denominator.
[tex]x * \frac{-72}{x} = x * 9[/tex]
⇒ [tex]-72 = x * 9[/tex]
Step 3: Re-order terms so constants are on the left.
[tex]-72 = x * 9[/tex]
⇒ [tex]-72 = 9x[/tex]
Step 4: Divide both sides by the same factor.
[tex]-72 = 9x[/tex]
⇒ [tex]\frac{-72}{9} = \frac{9x}{9}[/tex]
Step 5: Simplify.
Divide the numbers.[tex]\frac{-72}{9} = \frac{9x}{9}[/tex]
⇒ [tex]-8 = \frac{9x}{9}[/tex]
Cancel terms that are in both the numerator and denominator.[tex]-8 = \frac{9x}{9}[/tex]
⇒ [tex]-8 = x[/tex]
Move the variable to the left.[tex]-8x = x[/tex]
⇒ [tex]x = -8[/tex]
Hence, [tex]x = -8[/tex] is your answer.

A net of a square pyramid is shown below. 5.95 cm 5.1 cm What is the surface area, in square centimeters, of the pyramid.
Answer:
86.7
Step-by-step explanation:
L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7
The surface area of the square pyramid is 92 square centimeters.
The given figure is a square pyramid.
We have to find the surface area.
Surface area = a² + 2a√(a²/4 + h²)
a is 5.1 cm and h is height which is 5.95 cm.
Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)
=26.01 + 10.2 √(26.01 /4 +35.4025)
=26.01+10.2 √6.5025+35.4025
=26.01+10.2√41.905
=92 square centimeters.

Find the interquartile range (IQR) of your data. Show your work.
23, 75,79,99,105,110,110,142,149,168,168,170,183,195,202
Please help I don't understand!
Answer:
Interquartile Range = 71
Step-by-step explanation:
The interquartile range is the middle 50% of the data set. First you calculate the location of the 3rd quartile (75% of the data set) by computing:
LQ3 = (75/100)(n + 1) -> here n is the number of observations you have, so 15. You can now compute LQ3 = (75/100)(16) = 12
The data at location 12 of your data set is 170.
Now you compute the 1st quartile (25% of the data set):
LQ1 = (25/100)(16) = 4
The data at location 4 of your data set is 99.
The difference between the 3rd quartile (170) and the 1st quartile (99) is your interquartile range:
IQR = 170 - 99 = 71

What is the equation of the line in slope intercept form that has a slope of 1/2 and passes through (2,3)
Answer:
y = 1/2x + 2
*view the attached graph to double check the answer*
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = mx + b
y = 1/2x + b
(2, 3) ==> substitute the numbers into the equation
y = 1/2x + b
3 = 1/2(2) + b
3 = 1 + b
-1 -1
2 = b
Our final equation: y = 1/2x + 2
Check your answer using (2, 3):
y = 1/2x + 2
3 = 1/2(2) + 2
3 = 1 + 2
3 = 3
This statement is correct

This team had 195 strike outs in one season
explain how the models in questions 4 and 5 are the same
Answer:
Hi!
So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.
For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.
Hope this helps! :)

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.

During science class, Jack, Jeff, and Jill measure the length of their bean sprouts. Jeff’s sprout is 0.9 times the length of Jack’s, and Jill’s is 1.08 times the length of Jack’s. Whose bean sprout is the longest?Why?
Answer:
Jill's is the longest.
if jeffs is 0.9 times the length of jacks, his is lesser than jacks. e.g. 2×0.9=1.8. Jeff's will always be shorter. since we know Jacks is over 1, Jill's will always be taller because 2×1.08=2.16 or Jill's length.
