A photographic negative is 2 in. by 1.5 in. An
enlarged print from this negative has a length
of 9 in. as its shorter side. What is the length of
its longer side?
Answer:
The length of the longer side is 12 in
Step-by-step explanation:
Scaling
The dimensions of the photographic negative are 2 in by 1.5 in.
An enlarged print of it has a length of 9 in and it's equivalent to the shortest side.
Since the shortest side of the negative is 1.5 in, the scale factor is 9/1.5 = 6.
The longer side should have been enlarged by the same factor, thus the longer side is 2*6 = 12 in
The length of the longer side is 12 in

The volume of a sphere is 36 ft. What is the radius of the sphere? Use the formula V = ar to find your
3
answer.
The radius of the sphere is
feet.
Answer:
Radius of sphere = 3 feet
Step-by-step explanation:
The volume of sphere is 36 π ft³.
We need to find the radius of sphere.
The formula used is: [tex]Volume\:of\:sphere=\frac{4}{3}\pi r^3[/tex]
Putting value of volume and finding radius
[tex]Volume\:of\:sphere=\frac{4}{3}\pi r^3\\36\pi =\frac{4}{3}\pi r^3\\r^3=36 \pi \times \frac{3}{4\pi} \\r^3=9 \times 3\\r^3=27\\Taking\:cube\;root\:on \:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{27}\\r=3[/tex]
So, Radius of sphere = 3 feet

A ball is thrown from a mountain 960 feet high, into the air with an upward velocity of 64 ft/s. When did the ball hit the
ground? And What was the max height it reached?
Answer:
The ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
Step-by-step explanation:
Height of a mountain, h = 90 feet
Upward velocity of a ball, u = 64 ft/s
Its height as a function of time can be written by using the second equation of motion as follows :
[tex]f(x) = -16t^2 + 64t + 960[/tex] .....(1)
When it will hit the ground, f(x) = 0
[tex]-16t^2 + 64t + 960=0\\\\16(-t^2+4t+60)=0\\\\-t^2+4t+60=0[/tex]
It is quadratic equation.
t = -6 s and t = 10 s
Neglecting -6 seconds, the ball will hit the ground at 10 seconds.
For maximum height,
Put f'(x) = 0
[tex]-32t+64=0\\\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]
Put t = 2 in equation (1)
[tex]f(2) = -16(2)^2 + 64(2) + 960\\\\=1024\ \text{feet}[/tex]
Hence, the ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the rug?
Answer:
2 3/20 mStep-by-step explanation:
The area is the product of the length and width
The area = 7 1/6 m² = 43/6 m²The length = 3 1/3 m = 10/3 mWidth = ?
A = lww = A/lw = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 mThe width is 2 3/20 m

115/15+126/15
241/15= 16 1/15
I hope this helps:
Answer:
16 1/15
Step-by-step explanation:
Add the whole numbers. 7+8=15
Now, combine the fractions 2/3 and 2/5. To do so, you need a common denominator. The LCD between 3 and 5 is 15.
Whatever you do to one side you must do to the other.
(5/5) 2/3+ 2/5 (3/3)
10/15+6/15=16/15
15+16/15
16/15 is an improper fraction, so convert this fraction to a mixed number.
16/15= 1 1/15
Finally, add the two together. 15+ 1 1/15=
16 1/15
The area of a circular mouse pad is 64 square inches. Use 3.14 for 7. Estimate its radius to the nearest integer.
Answer:
about 4.52
Step-by-step explanation:
Since pi times radius squared is the formula for area, you would first divide 64 by 3.14 to get about 20.4. Then since you square the radius, you would do the opposite and find the square root which is about 4.52.

write the equation of a quadratic function that contains the points (1,21), (2,18), and (-1,9)
Answer:
The equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is [tex]y = -3\cdot x^{2}+6\cdot x +18[/tex].
Step-by-step explanation:
A quadratic function is a second order polynomial of the form:
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.
From Algebra we understand that a second order polynomial is determined by knowing three distinct points. If we know that [tex](x_{1}, y_{1}) = (1, 21)[/tex], [tex](x_{2},y_{2}) = (2,18)[/tex] and [tex](x_{3}, y_{3}) = (-1, 9)[/tex], then we construct the following system of linear equations:
[tex]a+b+c = 21[/tex] (2)
[tex]4\cdot a + 2\cdot b + c = 18[/tex] (3)
[tex]a - b + c = 9[/tex] (4)
By algebraic means, the solution of the system is:
[tex]a = -3[/tex], [tex]b = 6[/tex], [tex]c = 18[/tex]
Therefore, the equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is [tex]y = -3\cdot x^{2}+6\cdot x +18[/tex].
Write an equation of the line that passes (-3,3) and is perpendicular to the line 2y=8x-6
Answer:
2y=8x-30 or -4x+y=-15
Step-by-step explanation:
Answer: y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4

The equation of the line in the given graph, in slope-intercept form, is determined as: y = 1/2x + 4.
What is the Equation of a Line?In slope-intercept form, we can express the equation of a line as, y = mx + b, where, m is the slope and b is the y-intercept of the graph.
Slope of the line (m) = change in y /change in x = 1/2
Y-intercept (b) = 4
Substitute m = 1/2 and b = 4 into y = mx + b:
y = 1/2x + 4
The equation of the line is: y = 1/2x + 4.

The pie chart represents the proportion of how Colin spent the £900 he took on holiday all values are in degrees workout how much he spent on each category
Answer:
£180,£540 and £180
Step-by-step explanation:
Looking at the information presented, we don't have the percentages given neither do we have the items bought
However, let's say the money was spent on drinks, hotel reservations and food.
20% on food
60% on hotel reservations and
20% on transportation
We can now compute the individual cost of the a amount spent on each category from their percentage
For food
=20/100*900
=0.2*900
=180
Hotel reservations
=60/100*900
=0.6*900
=540
Foe transportation
=20/100*900
=0.2*900
=180
So, if you have your data, only follow the steps above and you will get your answers
To check, when we add all the amounts together they should sum up to 900
180+540+180=900

this table shows how many sophomores and juniors attended two school events. what is the probability that a randomly chosen person from this group is a junior? round your answer to two decimal places.
Probabilities are used to determine the chances of an event. Here, we want to calculate the chances of selecting a junior student. The probability of selecting a junior is 0.44.
From the table, we have:
[tex]Junior = 60[/tex]
[tex]Total = 137[/tex]
So, the probability of Junior is
[tex]P(Junior) = \frac{Junior}{Total}[/tex]
This gives:
[tex]P(Junior) = \frac{60}{137}[/tex]
[tex]P(Junior) = 0.437[/tex]
Approximate
[tex]P(Junior) = 0.44[/tex]
Hence, the probability of selecting a junior is 0.44
