Answer:
The original length is 9 cm and the original width 5 cm
Step-by-step explanation:
The area of a rectangle A is given as the product of its' length L and width W.
Given that the width of a rectangle is 4cm less than the length then
W = L - 4
If each dimension were increased by 3cm, then the new
Length
= L + 3
Width
= W + 3
the width of the new rectangle formed would be 2/3 the length of the new rectangle
W + 3 = 2/3(L + 3)
3W + 9 = 2L + 6
3W = 2L +6 - 9
3W = 2L - 3
Recall that W = L - 4
3(L - 4) = 2L - 3
3L - 12 = 2L - 3
3L - 2L = 12 - 3
L = 9 cm
W = 9 - 4
= 5 cm

A sum of was to be shared among three siblings, Rombe nikita and kimroy in the ratio 3:7:9. it nikita received $2500 more than Rambo. Evaluate.
i) The sum of money shared...
ii) kimroy's share. please hurry!!! and give me the full working out to solve the solution.
Answer:
Step-by-step explanation:
Formula: share/# of parts × amount = Total
# of parts= 3+7+9= 19
so= 3/19 × $2500 = $7500
= $7500 × 3
= $22500
do the same for the others to get the shared. oh and also 3/19 is a fraction. hope it was helpful.✌

4e-12=36 how do u solve this
Answer:
4e-12=36
4e=36+12
4e=48
e=12
Step-by-step explanation:
pasos
1mover la constante a la derecha añadiendo su opuesto en ambos lados (+12 +12)
2debido a que dos opuestos sumados dan cero, remuévenos la expresión es decir (4e=36+12)
3sumar los números es decir sumar (36+12)
4divide ambos lados de la ecuación entre 4 es decir (4e/4 =48/4)
5cualquier expresión dividida entre si es igual a 1
6calcular el cociente es decir (48/4 e=12)
Answer:
12
Step-by-step explanation:
4e=36+12
4e=48

A rectangle of length 14 cm and breadth 7 cm is folded into a right circular cylinder. How many revolutions does the cylinder need to make to cover an area of 784 sq.Cm
Answer:
n = 8
Step-by-step explanation:
Given that,
Length and breadth of a rectangle are 14 cm and 7 cm.
The area of rectangle is given by :
[tex]A=l\times b\\\\A=14\times 7\\A=98\ cm^2[/tex]
Let n be the number of revolutions the cylinder need to make to cover an area of 784 sq.cm.
So,
[tex]n=\dfrac{784}{98}\\\\n=8[/tex]
Hence, there are 8 revolutions.

Solving the formula P = 2L + 2W for W is NOT equivalent to which equation?
Answer:
3rd one
Step-by-step explanation:
2l + 2w = P
2w = P - 2l
w = P - 2l / 2
Therefore, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]2L + 2w = P\\\\2(L+w)=P\\\\L+w=\frac{1}{2}P\\\\w=\frac{1}{2}P-L\\\\w=\frac{P-2L}{2}\\\\w=P-\frac{1}{2}L[/tex]
Hence, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].

Step-by-step explanation:
Hey There!
Look at the image for the rule of a 30- 60 - 90 triangle
x = 5
the hypotenuse would be x2 so 10
the longer leg would be x[tex]\sqrt{3}[/tex]
So the first triangle is the right answer
The first triangle in the figure is a 30°-60°-90° triangle.
What is a triangle?A triangle is a polygon with three sides and three angles.
Given are triangles, we need to see which of them are a 30°-60°-90° triangle,
So,
In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse.
So you have to choose one with 5 & 10.
Use the Pythagorean theorem to calculate the remaining side
a² + b² = c²
5² + b² = 10², so b² = 100-25 √b²=√75 so √(25)(3)
b= 5√3
Hence, the first triangle in the figure is a 30°-60°-90° triangle.

help.. again please tysm :)
Answer:
No Solutions
Step-by-step explanation:
The two points are (3,2) and (-2,-2)
Slope is y change over x change.
So... -2-2 over -2-3 equals to -3-(-2) over -2-(-2).
That is -3+2 over -2+2 which is -2 over 0.
You can't divide by zero so the slope is "NoSolutions"

Answer:
A) y=3x+1
Step-by-step explanation:
Use the formula y=mx+b
m is the slope and b is the y intercept
the graph starts on 1 on the y axis so you replace 1 for b
the slope goes up 3 and over one, giving the fraction 3/1 or just 3. so you replace 3 for m.
