A rectangular sheet of paper has a perimeter of 60cm. When it is folded in half along its longer line of symmetry, the perimeter of the rectangle which this creates is 49cm. What are the dimensions of the original shape?
Answers
Answer:
Dimensions of the original rectangle:
Length = 19 cm
Width = 11 cm
Step-by-step explanation:
Let
Length = x
Width = y
Original rectangle:
2(Length + width) = 60
2x + 2y = 60
New rectangle has same length with original rectangle but half of the width of the original rectangle when folded
Length = x
Width = 1/2y
2(Length + 1/2width) = 49
2x + y = 49
2x + 2y = 60 (1)
2x + y = 49 (2)
Subtract (2) from (1) to eliminate x
2y - y = 60 - 49
y = 11
Substitute y = 11 into (2)
2x + y = 49
2x + 11 = 49
2x = 49 - 11
2x = 38
x = 38/2
x = 19
Dimensions of the original rectangle:
Length = 19 cm
Width = 11 cm

Jon is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by h(t)=5+25t-16t^2, where t is the time in seconds.
a) How much time will pass before Jon hits the ball? (round to the nearest tenth of a second)
b) What is the time in which the maximum height the ball attains? ( to the nearest hundredth of a second)
Answers
Answer: A= 1.60 sec
And I am not sure if B is correct, but I got 14.77 ft.
Step-by-step explanation:
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -
h(t) = 5 + 25t - 16t²
where [t] is the time in seconds.
[A] -
At h = 4ft, we can write -
4 = 5 + 25t - 16t²
- 16t² + 25t + 1 = 0
On solving, we get -
t = 1.602 seconds
[B] -
We have -
h(t) = 5 + 25t - 16t²
For maximum height -
dh/dt = 0
d/dt(5 + 25t - 16t²) = 0
0 + 25 - 32t = 0
32t = 25
t = 25/32
t = 0.79 seconds
Therefore -
t = 1.602 seconds will pass before Jon hits the ball.At t = 0.79 seconds the ball attains maximum height.To solve more questions on Equation Modelling, visit the link below -

A hemisphere fits snugly inside a cylinder with a radius of 12 cm. A cone fits snugly inside the same hemisphere. What is the volume of the cylinder in terms of LaTeX: \piπ? Show all work.
Answers
Answer:
The volume of the cylinder is 1,728·π cm³
Step-by-step explanation:
The given parameters are;
The radius of the cylinder, r = 12 cm
The location of the hemisphere = Inside the cylinder
The size relationship between the hemisphere and the cone = Snuggly fit
Therefore, we have;
The radius of the hemisphere = The radius of the cylinder = 12 cm
The height of the cylinder, h = The radius of the hemisphere = 12 cm
The volume of the cylinder, V = π·r²·h
Where;
h = 12 cm
r = 12 cm
Therefore;
V = π·r²·h = π × (12 cm)² × 12 cm = (12 cm)³·π = 1,728·π cm³
The volume of the cylinder, V, in terms of pi (π) is, V = 1,728·π cm³.
Determina el número de átomos que tiene una
muestra de 0.7 gramos de uranio puro si la
masa de un átomo de uranio es de 4 x 10^-25 kg
Answers
Tomando el cociente entre la masa de la muestra y la masa de un átomo, veremos que hay 1.7*10^21 átomos de uranio en la muestra.
¿Como podemos determinar el número de átomos?Para determinar el número de átomos en la muestra, simplemente debemos dividir la masa de la muestra (0.7 gramos) por la masa de un átomo de uranio (4*10^(-25) kg)
Donde la complicación viene por que tenemos distintas unidades.
Para resolver esto, podemos escribir la masa de la muestra en kilogramos.
Sabemos que: 1g = 1*10^-3 kg
Entonces podemos reescribir la masa de la muestra como:
0.7g = (0.7)*(10^-3 kg) = 7*10^-4 kg
Ahora si podemos tomar el cociente, el número de átomos esta dado por:
[tex]N = \frac{7*10^{-4}kg}{4*10^{-25}kg} = 1.7*10^{21}[/tex]
Así podemos concluir que hay 1.7*10^21 átomos de uranio en la muestra.

Answer:
12. (x, D, E, F) = (8, 38°, 75°, 67°)
13. (x, P, Q, R) = (13, 126°, 30°, 24°)
Step-by-step explanation:
The sum of angles in a triangle is 180°. We choose to write the equations assuming all measures are degrees.
12. (5x -2) +(9x +3) +(11x -21) = 180
25x = 200 . . . . . . . add 20, simplify
x = 8 . . . . . . . . . divide by 25
Then the angle measures are ...
∠D = 5(8) -2 = 38°
∠E = 9(8) +3 = 75°
∠F = 11(8) -21 = 67°
__
13. (10x -4) +(4x -22) +(x +11) = 180
15x = 195 . . . . . . . . . . add 15, simplify
x = 13 . . . . . . . . . divide by 15
Then the angle measures are ...
∠P = 10(13) -4 = 126°
∠Q = 4(13) -22 = 30°
∠R = 13 +11 = 24°

Answer:
5^2+h^2=12^2, the answer would be ~10.97 ft.
Step-by-step explanation:
I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.
Pythagorean theorem is :
a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.
Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

4. A right triangle has legs with lengths of 6 feet and 9 feet. The hypotenuse of the triangle, in feet,
is between:
A. 4 and 5
B. 6 and 9
C. 9 and 10
D. 10 and 11
E. 11 and 13
Answers
C^2 = A^2 + B^2
C^2 = (6)^2 + (9)^2
C^2 = 36 + 81
C^2 = 117
C = square root of 117
C = About 10.81 feet
So, in conclusion, the hypotenuse or the longest side of the triangle in feet is: D. Between 10 feet and 11 feet.
Answer:
D. 10 and 11
Step-by-step explanation:
This problem would use pythagorean theorem because we're finding the hypotenuse of a right triangle. This is its standard equation:
[tex]a {}^{2} + {b}^{2} = {c}^{2} [/tex]
The legs represent [tex]a[/tex] and [tex]b[/tex] respectively, and [tex]c[/tex] represents the hypotenuse. After plugging in the legs' respective values, the equation looks like this:
[tex]6^{2} + {9}^{2} = {c}^{2} →36 + 81 = {c}^{2} →117 = c^{2} [/tex]
To isolate [tex]c[/tex], you would find the square root of [tex]117[/tex]. In this case, we're just finding which integers[tex] \sqrt{117} [/tex] is between. [tex]\sqrt{100}(=10)[/tex] is the closest integer value below [tex]\sqrt{117}[/tex] and [tex]\sqrt{121}(=11)[/tex] is the closest integer value above [tex]\sqrt{117}[/tex]. So the answer is D. 10 and 11.

do 252/448 and 36/64 form a proportion?
Answers
Answer:
252/448 and 36/64 form a proportion
Step-by-step explanation:
The easiest way to do this is to let 252/448 = 36/64
Then cross multiply to get 252(64) = 36(448)
16128 = 16128
Since the two products are equal, then 252/448 and 36/64 form a proportion. If the the two products were unequal, then the two fractions would NOT form a proportion.

Answer:
I would say graph a is the correct answer
Step-by-step explanation:
Based on the given inequality of y≥ x - 1, the graph that matches it best is C. Graph A.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
We know that how are inequalities graphed:
When graphing an inequality with the "greater or equal" and "less or equal" signs, the line will be a steady line as shown by graphs A and B.
If y is the larger or equal variable, the shaded area will be to the left of the line.
The inequality is y≥ x - 1 which means that the line should be steady and the shading should be on the left of the line.
Graph A is therefore the correct graph.

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
VolumeVolume is the amount of space that is occupied by a three dimensional object.
The volume of a cone (V) is given by:
V = (1/3)πr²h
Where r is the radius and h is the height.
For a radius of 1:
3π = (1/3)π*(1)² * h
h = 9
For a radius of 2:
3π = (1/3)π*(2)² * h
h = 2.25
For a radius of 5:
3π = (1/3)π*(5)² * h
h = 0.36
For a radius of 12:
3π = (1/3)π*(12)² * h
h = 0.02
