Triangle 2 is a scale drawing of Triangle 1.
Based on the information in the diagram, what is the length of side b?
Answer:
36 would be the answer
Step-by-step explanation:
The length of side b in triangle 2 is 36.
What are similar triangles?Two triangles are similar if they have the same corresponding angles and their corresponding sides are in equal ratios.
Given that, there are two triangles, triangle 2 is a scale drawing of triangle 1.
Therefore, Δ 1~Δ 2,
According to the definition of similar triangles,
6/27 = 10/45 = 8/b
Therefore,
8/b = 6/27
8/b = 2/9
b = 36
Hence, the length of side b in triangle 2 is 36.

Bob wants to buy a car. He puts $8,000 in a savings account that has a
simple interest rate of 4%. If he leaves his money in the account for 3
years, how will be in his account in TOTAL after 3 years?"
A-$960
B-8,960
C-7,040
D-$320
9514 1404 393
Answer:
B. $8,960
Step-by-step explanation:
Use your number sense.
If the account earns interest, the balance will increase from the initial deposit of $8000. The only sensible answer choice is B, $8960.
__
If you want to actually figure it out, the balance is given by ...
A = P(1 +rt)
A = 8000(1 +0.04·3) = 8000(1.12) = 8960 . . . . matches choice B
Write an explicit formula for an, the n^th term of the sequence 22, 20, 18, ....
Answer:
[tex]a_n=a+(n-1)d[/tex]
Step-by-step explanation:
The given sequence is 22, 20, 18, ...
We need to find the explicit formula for an.
First term is 22
Second term = 20
Third term = 18
We can write the formula as :
[tex]a_n=a+(n-1)d[/tex]
Where
a is 22
d is common difference = 20-22 = -2
Forth term will be :
[tex]a_4=22+(4-1)(-2)\\\\=22-6\\\\=16[/tex]
Hence, the formula is [tex]a_n=a+(n-1)d[/tex].

Alvin is 7 years younger than Elgas. The sum of their ages is 63. What is Elgas age?
Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.

Answer:
113.1 cm²
Step-by-step explanation:
we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius
so first, we need to find the radius
the length of the radius is half the length of the diameter
so that means that r=d/2
r=d/2
r=12/2
r=6
therefore the length of the radius is 6
now square 6, which is the same as multiplying it by itself
6²=36
now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7
so if we were to do 22/7 for instance,
36*22/7≈113.14
round that to 113.1
there's your answer :)
Hope this helps!

Answer:
A) The width is 12 cm; the average time is 3 minutes
Step-by-step explanation:
[tex]\frac{5}{3}= \frac{20}{y}[/tex]
Cross multiply.
5 × y = 3 × 20
5y = 60
5y ÷ 5 = 60 ÷ 5
y = 12
The width is 12 cm. Moving onto the time.
[tex]\frac{12}{4} =\frac{y}{1}[/tex]
Cross multiply.
4 × y = 12 × 1
4y = 12
4y ÷ 4 = 12 ÷ 4
y = 3
The time is 3 minutes.

Step-by-step explanation:
You would have to divided the recent pages (200) with the previous (5)
and you would get 40 and then you would multiply the divided amount page with the 4 minutes and you would get 160
How it was worked out:
200 / 5 = 40, 40 x 4 = 160
