15.it will take 88 minutes to add 16 seats.
It will take 104.5 minutes to add 19 seats.
Step-by-step explanation:
Let m represent number of minutes.
We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.
We will use proportions to solve our given problem.
To find the time taken to add 16 seats, we will in our proportion as:
Therefore, it will take 88 minutes to add 16 seats.
To find the time taken to add 19 seats, we will in our proportion as:
Therefore, it will take 104.5 minutes to add 19 seats

Answer:
JL = 54
Step-by-step explanation:
JL = JK + KL
JK = KL
8x+11 =14x-1
12 = 6x
x = 2
substitute for x:
8(2)+11 + 14(2)-1 = JL
JL = 16+11+28-1
JL = 54

Enlarge the triangle by scale factor -2, using point (8,8) as the centre of enlargement
(please hurry 15 points)
Answer:
I understand you probably don't need this anymore but here is the answer anyway.
Step-by-step explanation:
So what you want to do is draw a line from a corner to the centre of enlargement (I'll use the one at (9, 10) ). Then you see that it take 2 boxes to get to that, keep the line going through for double as much as it took to reach the centre of enlargement, this is because the scale factor is two. Do this for every corner, going through the centre of enlargement for the double the length it took to get to it (plot a cross at each bit you end up). Finally, remove the lines you used and connect the crosses. This method may be a bit confusing and someone who understands it more than me would probably explain what the minus means, if I explain it will probably make this more confusing. Hope this Helps!

Steph makes scones in three flavours: cheese, fruit and plain.
She makes:
• 4 times as many fruit scones as cheese scones,
• 3 times as many plain scones as cheese scones.
She sells each scone for the same price.
She makes a total of £96 from the sale of all the scones.
How much does she make from the sale of the plain scones?
Answer:
The amount she makes from the sale of plain scones is £36
Step-by-step explanation:
The number of flavors of scones Steph makes =
The number of fruit scones she makes = 4 × The number of cheese scones she makes
The number of plain scones she makes = 3 × The number of cheese scones she makes
The price at which she sells the cheese scones = The price at which she sells the fruit scones
The price at which she sells the cheese scones = The price at which she sells the plain scones
The total amount she makes = £96
Let, 'x', represent the number of cheese scones she makes
Therefore, we have;
The number of fruit scones she makes = 4·x
The number of plain she makes = 3·x
∴ The total number of scones she makes = 4·x + 3·x + x = 8·x
The total number of scones she makes = 8·x
The total amount she makes from selling the 8·x scones she makes = £96
∴ 8·x = £96
x = £96/8 = £12
The amount she makes from the sale of 'x' number of scones = £12
The number of plain scones she makes = 3·x
From the sale of '3·x' number of plain scones, she makes = £12 × 3 = £36
Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
d
=
12.5
×
t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y
=
k
x
where
y
and
x
are the related quantities and
k
is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

The length of one base of a trapezoid is 19 meters and the length of the median is 23 meters. Find the length of the other base,
Answer:
27
Step-by-step explanation:
19+x/2=23
19+x=46
x=27
or 19-23=4
23+4=27
The length of the other base of the trapezoid is 27 meters.
What is a Trapezoid?A trapezoid is a polygon with four sides, it has one pair of parallel sides.
The length of the base of a trapezoid is 19 meters.
The length of the median is 23 meters.
The median in a trapezoid is a line that is in the drawn in the mid way of the two non-adjacent sides.
The value of median is half of the bases added together.
Median = (1/2) ( Base₁ + Base₂)
Substituting the values in the formula to obtain the value of the other base.
Let x be the length of the other base,
23 = (1/2) * ( 19 + x)
23 *2 = 19+x
46 = 19 +x
x = 27 meters
The length of the other base is 27 meters.
