A pen cost $40 and the book cost $10
The word problem that can be represented by the equation is: John bought one pen and one book for $50. He went the next day and bought 2 pens and 4 books for $120.
x + y = 50 ....... i
2x + 4y = 120 .... ii
Let x = pen
Let y = book.
From equation i, x = 50 - y
Since 2x + 4y = 120
2(50 - y) + 4y = 120
100 - 2y + 4y = 120
Collect like terms
-2y + 4y = 120 - 100
2y = 20
y = 10
Therefore, a book cost $10
Since x + y = 50
x + 10 = 50
x = 50 - 10
x = 40
A pen cost $40

At the end of the year, cars made in the current year are marked down to make room for next year's models. One particular model has a sale price of $12,806, which is 24% less than it sold for when it was new. What was the original price of the vehicle?
9514 1404 393
Answer:
$16,850
Step-by-step explanation:
The sale price is 1 -24% = 76% of the original price (p). An equation is ...
12806 = 0.76p
12806/0.76 = p = 16850
The original price of the vehicle was $16,850.
Plastic parts produced by an injection-molding operation are checked for conformance to specifications. Each tool contains 10 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. An inspector chooses 2 part(s) from among the 10 at random. Two cavities are affected by a temperature malfunction that results in parts that do not conform to specifications.
a. How many samples contain exactly 1 nonconforming part?
b. How many samples contain at least 1 nonconforming part?
Answer:
16 ;
17
Step-by-step explanation:
Number of cavities = 10
Number of parts chosen = 2
Number of cavities affected by temperature malfunction = 2
A.)
Number of samples that contain exactly one conforming part :
2C1 * 10-2C2-1
2C1 * 8C1
Combination formula :
nCr = n! ÷ (n-r)! r!
Using calculator :
2C1 * 8C1 = 2 * 8 = 16
B)
b. How many samples contain at least 1 nonconforming part?
10C2 - 8C2 = 45 - 28 = 17

M
А
8
A
S
I
T
Answer:
40
Step-by-step explanation:
A rhombus diagonals form perpendicular angles. It also bisects and form 4 right triangles. Looking at triangle MAS, we can use pythagorean theorem to find the side MA.
[tex]ms {}^{2} + sa {}^{2} = {ma}^{2} [/tex]
ms=6, sa =8 so we plug that in.
[tex]6 {}^{2} + {8}^{2} = ma {}^{2} [/tex]
Simplify
[tex]36 + 64 = ma {}^{2} [/tex]
[tex]100 = ma {}^{2} [/tex]
take sqr root
[tex] \sqrt{100} = ma[/tex]
[tex]ma = 10[/tex]
Now let find the perimeter
Since perimeter of a Rhombus is 4a where a is the length of a side. We plug it in
[tex]4(10) = 40[/tex]
The answer is 40
