Answer:
The scaled factor is 3.
Step-by-step explanation:
Consider the figure shown below:
It is given that: A rectangle N has an area of 5 square units. James drew a scaled version of Rectangle N and labeled it Rectangle P.
We need to find the scale factor which is used by James.
First, we will calculate the area of Rectangle P by counting the number of squares shown in the figure.
Area of rectangle P = 45 square unit
Let x be the scaled factor.
To scale the rectangle we need to multiply both the length and breadth of the rectangle N by x and the scaled area should be equal to 45.
[tex][x\times \text{Length} ][x \times \text{breadth}]=45[/tex]
[tex]x^2(\text{Length} \times \text{breadth})=45[/tex]
It is given that area of the rectangle N is 5 square units, so put length time breadth as 5.
[tex]x^2(5)=45[/tex]
[tex]x^2=9[/tex]
[tex]x=3[/tex]
Hence, the scaled factor is 3.
Find the missing number of each unit rate. 155 = ?1 246 = ?1
worth 15 points!!!
This is an incomplete question, the correct question is given below.
Find the missing number of each unit rate [tex]\frac{15}{5}=\frac{?}{1}[/tex] and [tex]\frac{24}{6}=\frac{?}{1}[/tex]
Answer : The missing number of each unit rate of [tex]\frac{15}{5}=\frac{?}{1}[/tex] and [tex]\frac{24}{6}=\frac{?}{1}[/tex] are, 3 and 4 respectively.
Step-by-step explanation :
As we know that a unit rate is a rate in which 1 is present in denominator.
Or we can say that,
A unit rate is also called a single unit rate that means it will compare 1 unit of some quantity to a different units of a different quantity.
As we are given that that unit rates:
[tex]\frac{15}{5}=\frac{?}{1}[/tex] and [tex]\frac{24}{6}=\frac{?}{1}[/tex]
Now we have to determine the missing number of each unit rates.
So, we can write the given expression as:
[tex]\frac{15}{5}=\frac{?}{1}[/tex]
When are dividing 15 by 5, we get:
[tex]\frac{15}{5}=\frac{3}{1}[/tex]
Thus, the missing number is, 3
And
[tex]\frac{24}{6}=\frac{?}{1}[/tex]
When are dividing 24 by 6, we get:
[tex]\frac{24}{6}=\frac{4}{1}[/tex]
Thus, the missing number is, 4
Solve the problem By using area models Problem: shereen 119 books into 7 even piles .How many books did shereen put in each pile ?
Answer:
the 17 books should be put in each pile
Step-by-step explanation:
The computation of the number of books in each pile is shown below:
Given that
There are 119 books
And there are 7 piles
So, the number of books in each pile is
= 119 books ÷ 7 piles
= 17 books
Hence, the 17 books should be put in each pile
So the same is to be conisdered and relevant too

Answer:
B. 7[tex]\sqrt{3}[/tex]
Step-by-step explanation:
The amount of time T (in years) it will take for a population of a certain species to grow from 3500 to a can be modeled by the function Y(a)=log _(5) (a/3500)^1/0.03. Which function is equivalent?
Answer:
Option C is correct
Step-by-step explanation:
Here, we want to find which of the equations in the option is same as that in the question
The rule to use is that;
Loga B^y
= ylogaB
And also:
loga(X/Y) = logaX-logaY
Now, we start by applying these equations;
T(a) = log5 (a/3500)^1/0.03
T(a) = 1/0.03log5(a/3500)
T(a) = 1/0.03log5a - 1/0.03log53500
This makes the third option correct

= 64π ≈ 201 cm
V (sphere) = 4/3π[tex]r^{3}[/tex]/2

Find the height of a cylinder with a volume of 720n and a
radius of 6.
Answer:
height is approx 6.4
Step-by-step explanation:
V(cyl) = π[tex]r^{2}[/tex]h
720 = π·6^2·h
720 = π·36·h
20 = π·h
20÷ π = h
Find the 62nd term of the following sequence:
(-21, – 27, - 33, - 39,...)
Answer:
-387
Step-by-step explanation:
First term (T1) = -21 = a
second term (t2) = - 27
common difference (d) = t2 - t1 = - 27 + 21 = - 6
Now
Tn = a + ( n - 1) d
T62 = - 21 + ( 62 - 1 ) - 6
= - 21 -366
= -387

Find a point that lies on the line defined by
3x + 6y = 2
Answer:
(0, 1/3)
Step-by-step explanation:
choose any value for x, x = 0
then find the corresponding y value by plugging in x to equation,
3(0) + 6y =2
6y = 2
y = 2/6 = 1/3
thus point on this line is (0, 1/3)

find the value of a and b?
9514 1404 393
Answer:
a = -2b = 1Step-by-step explanation:
Subtracting the remainder from the original polynomial gives a polynomial that has (x^2 -1) as a factor. Dividing, we find the quotient and remainder to be ...
(x^5 +ax^3 +bx^2 +x -1)/(x^2 -1) = (x^3 +(1+a)x +b) remainder (2+a)x +(b -1)
Since we want the remainder to be zero, we require ...
2+a = 0 ⇒ a = -2
b -1 = 0 ⇒ b = 1
_____
The attachment shows the division as given in the problem statement (with the given remainder expression).

Answer:
670.21ft^3
Step-by-step explanation:
Volume of a cylinder=pi*r^2*h
Radius=8/2=4
Height=12
Volume=603.19
Volume of a cone=pi*r^2*(h/3)
radius=8/2=4
Hight=16-12=4
Volume=67.02
603.19+67.02=670.21ft^3

what is the solution for X in the equation 1/2 - x + 3/2 equals x - 4
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2−x+3/2=x−4
1/2+−x+3/2=x+−4
(−x)+(1/2+3/2)=x−4(Combine Like Terms)
−x+2=x−4
−x+2=x−4
Step 2: Subtract x from both sides.
−x+2−x=x−4−x
−2x+2=−4
Step 3: Subtract 2 from both sides.
−2x+2−2=−4−2
−2x=−6
Step 4: Divide both sides by -2.
−2x/−2=−6/−2
x=3
