Answer:
14
Step-by-step explanation:
The total amount of bowls he can make given the pounds of clay and the pound needed to make a bowl = [tex]15\frac{5}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ×[tex]\frac{10}{7}[/tex] = 22.32
Number of bowls he can more more = total amount of bowls that can be made - number of bowls already made
22.32 - 8 = 14.32 bowls
Rounding off to the nearest whole number gives 14

During a scuba dive, Lainey descended to a point 18 feet below the ocean surface. She continued her descent at a rate of 25 feet per minute. Write an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 143 feet below the ocean surface. Use the variable t for time.
Answer:
Inequality representation :
18 + 25t ≤ 143 ;
t = 5
Step-by-step explanation:
Given that:
Initial dive, I = 18 feets
Descent rate, r = 25 feets / minute
Maximum depth reached = 143 feets
Time = t
Inequality representation :
18 + 25t ≤ 143
To solve for t
25t ≤ 143 - 18
25t ≤ 125
Divide both sides by 25
25t / 25 ≤ 125 / 25
t ≤ 5
Researchers are investigating the effectiveness of leg-strength training on cycling performance. A sample of 7 men will be selected to participate in a training program that lasts for one month. Peak power during cycling will be recorded for each man both before training and after training. The mean difference in times will be used to construct a 95 percent confidence interval for the mean difference in the population.When all other things remain the same, which of the following statements about the width of the interval is correct?A) The interval will be narrower if 15 men are used in the sample.B) The interval will be wider if 15 men are used in the sample.C) The interval will be narrower if 5 men are used in the sample.D) The interval will be narrower if the level is increased to 99% confidence.E) The interval will be wider if the level is decreased to 90% confidence.

My three cars can travel the same distance on a tank of gas. My second car gets 6 kilometers per liter more than
my first, but its tank holds 3 fewer liters than my first. My third car gets 6 kilometers per liter less than my first, but its tank holds 6 more liters
than my first. How many kilometers can each car travel on a tank of gas?
Answer:
16
Step-by-step explanation::
wrote on NEML, got it right,
Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds. The millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.
Given information
All three cars can travel the same distance on a tank of gas.
The second car gets 6 kilometres per liter more than the first, but its tank holds 3 fewer liters than the first.
The third car gets 6 kilometres per liter less than the first, but its tank holds 6 more liters than the first.
Suppose the first car runs m. kilometre per liter. Then the second car will run (m+6) kilometre per liter and third car runs (m-3) kilometre per liter.
Suppose the first car has l liter in the tank. Then the second car has (l-3) liter and third car has (l+6) liters in her tank.
DistanceDistance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds.
As the distance traveled by the first car is same as the second one. Hence,
[tex]\begin{aligned}\\\dfrac{m}{l} &=\dfrac{m+6}{l-3} \\ml-3m&=ml+6l\\m&=-2l\\\end[/tex]
Let the above equation is equation 1.
As the distance traveled by the second car is same as the third one. Hence,
[tex]\begin{aligned}\\\dfrac{m-3}{l+6} &=\dfrac{m+6}{l-3} \\ml-3m+9-3l&=ml+6l+6m+36\\l+m&=-3\\\end[/tex]
Put the value of m in the above equation from equation 1,
[tex]l-2l=-3\\l=3[/tex]
[tex]m=2\times3=6[/tex]
Thus the value of the m is 6.
With the millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?
maybe you can solve that? I'll solve it below.. but.. if you can.. try it now, on your own
below is my answer... don't look until you have solved yours :P
80+70= 150kph
when will this have traveled 50Km?
you may be able to see that it will take 1/3 of an hour to travel 50 km

You are making a scale model of your house. Your bedroom is 10'x8'. In your scale model, it will be the longer side of the bedroom will be 3 inches. How big will the shorter side be?
Answer:
2.4 inches
Step-by-step explanation:
Actual Dimension of bedroom = 10' * 8'
In the model ; longer side = 3 inches
Length of shorter side in the model ;
Longer side of actual bedroom = 10'
Scale factor * length = model length
Scale factor * 10 = 3
Scale factor = 3/10
Hence, length of shorter side :
Scale factor * actual length of shorter side
3/10 * 8
24 / 10
= 2.4 inches
what are the zeros of the quadratic equation (x-11)(x-5)=0
9514 1404 393
Answer:
11, 5
Step-by-step explanation:
Zeros are the values of x that make the product zero. The product will be zero if and only if one or more of the factors is zero.
x -11 = 0 ⇒ x = 11
x -5 = 0 ⇒ x = 5
The values x=11 and x=5 are zeros of the quadratic.

Step-by-step explanation:
The midpoint of any line segment is the average of the coordinates of the endpoints.
mp=((x2+x1)/2, (y2+y1)/2), in this case we have points (9,7) and (5,3) so

Part A is no because after subtracting it is 6/10 and 6/10 is not equal to 1/2
Step-by-step explanation:
First you make the fraction's denominator equal
2/5 = 4/10
Camen's water bottle is 1 8/10
Jorge's water bottle is 2 4/10
1/2 = 5/10
Make the fractions into a improper fraction
Camen's is 18/10
Jorge's is 24/10
subtract it
24 - 18 = 6
So Part A is no because after subtracting it is 6/10 and 6/10 is not equal to 1/2

How to find maxima?To find the maxima of any function it needs to differentiate with respect to the dependent variable and equate with zero to get stationary points.
After achieving the stationary points it needs to put on the double derivative of that function to check whether it's maxima or minima.
If the double derivative got negative then it will be maxima.
Given that function
f(x) = -0.001(x-600)² + 90
By differentiation
[tex]$f'(x)$[/tex] = -0.002(x - 600) + 90
Now equate with zero
-0.002(x - 600) + 90 = 0
x - 600 = 0
x = 600
Now checking the x at double derivative
[tex]$f''(x)$[/tex] at x = 600 it is coming out to -0.002 which is negative Hence, the 600 units will be the correct answer.

Step-by-step explanation:
Number of Blue pens in box A = b
Number of red pens in box A = r
BOX A :
Contains 10 pens that are either red or blue
b + r = 10
BOX B:
Contains 23 pens that are either red or blue ;
Red pens in box B = 2 tines the number of red pens in box A
Blue pens in box B = 3 times the number of blue pens in box A
