Step-by-step explanation:
Let L = length and W = Width
The problem says L = 2W
and
Area = LW = 21
Substitute
2W2 = 21
W2 = 10.5

At the library, 56 people borrowed
books on Monday. Then 48 people
borrowed books on Tuesday. On
Wednesday, 40 people borrowed
books. If this pattern continues,
how many people will borrow
books on Friday?
Answer:
24 people borrowed the books on Friday
Step-by-step explanation:
Every day, the number of books is being subtracted by 2.
56 - Monday (-8)
48 - Tuesday (-8)
40 - Wednesday (-8)
32 - Thursday (-8)
24- Friday
f(n+1)=5f(n), where f(1)=3 and n>1
Answer:
[tex]f(n) = \frac35 5^n[/tex]
Step-by-step explanation:
Let's assume the solution is of the form [tex]f(n) = \alpha k^n[/tex], where [tex]\alpha[/tex] is to be determined on the starting condition, and [tex]k \in \mathbb{R} \ne 0[/tex]
[tex]f(n+1) -5f(n) = 0\\\alpha k^{n+1} -5 \alpha k^n=0\\\alpha k^n (k-5) = 0 \rightarrow k= 5[/tex]
at this point we can use our starting condition to determine the value of [tex]\alpha[/tex]:
[tex]f(1)=3 \rightarrow \alpha 5^1 =3 \rightarrow \alpha =\frac 35[/tex]
Our solution is, thus [tex]f(n) = \frac35 5^n[/tex]

Leo practices piano for a
minimum of 90 minutes each
week. On Monday, he
practiced 10 minutes. For the
rest of the week, he practiced
in 20-minute sessions. How
many sessions would it take to
meet his goal?
Answer:
4 sessions.
Step-by-step explanation:
He starts with 10 minutes practiced and has to finish his quota in 20 minute sessions, so we can represent that with the equation 90=20x+10. Then solve for x.
90=20x+10
Subtract 10
80=20x
Divide by 20
x=4
It would take 4 sessions.
Answer:
1 10 min session + x 20 min sessions = 90 min
10+20x=90
20x=80
x=4 sessions

Polygon LMNPQR is shown on the coordinate grid and models the shape of a garden in a park,
Polygon LMNPQR will be dilated with the origin as the center of dilation to create polygon
L'M'N'P/Q'R'. The vertex Q' will be located at (21, 7).
Which rule best represents the dilation?
Dilation involves changing the size of the polygon
The best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]
How to determine the ruleThe coordinates of vertices Q and Q' are given as;
Q = (6,2)
Q' = (21, 7)
The scale factor of dilation is then calculated as:
[tex]k = \frac {Q'}{Q}[/tex]
So, we have:
[tex]k = \frac {(21,7)}{(6,2)}[/tex]
Factorize
[tex]k = \frac {7/2(6,2)}{(6,2)}[/tex]
Divide
[tex]k = \frac {7}2[/tex]
So, the transformation rule is:
[tex](x,y) \to \frac 72(x,y)[/tex]
Hence, the best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]

Given x + y = x ∙ y = 3, determine x3 + y3 ?
Answer:
Step-by-step explanation:
x³ + y³ = (x + y)(x² - xy + y²)
= (x + y)(x² + 2xy + y² - 3xy)
= (x + y)[(x + y)² - 3xy]
= 3(3² - 3(3)) = 3(0) = 0

If 50% of some number is 75, what is 200% of that same number?
Answer:
300
Step-by-step explanation:
A percentage is a unit of proportion that represents a ratio.
For this question let the unknown number be represented by the variable x. We know that 75 is 50% of x, or half of x. This means that we can find the unknown number by doubling 75.
75*2=150This means that x is 150. Next, we need to find 200% of 150. 200% of any number is that number times 2. So, to find the final answer we must once again double 150.
150*2=300So, the final answer is 300.
Answer:
Step-by-step explanation:
270
50% equals to 1/2 so 1/2x=75. Times 2 on both sides you get x=135.
So 135 is x and you multiply 135 by 200%. Which get you 270.
