Sandy cut a 151-centimeter board into five pieces. The three shortest pieces are the same length and the two longer pieces are each three centimeters longer than a short piece. How long is each piece?
Answer: The short piece is 29.6 cm long and 32.6 cm long.
Step-by-step explanation:
Let x = length of short pieces , y = lengthof longer pieces.
y=x+3 (i)
As per given,
3x+2y=151 (ii)
Substitute value of y from (i) in (ii), we get
[tex]3x+2(x+3)=151\\\\\Rightarrow\ 3x+2x+3=151\\\\\Rightarrow\ 5x=148\\\\\Rightarrow\ x=\dfrac{148}{5}=29.6[/tex]
Put value of in (i), we get
y=29.6+3= 32.6
Hence, the short piece is 29.6 cm long and 32.6 cm long.

Natalie needs to save $479.58 for a vacation. She saved $149.88, and earns $7.85 an hour working at the grocery store. How many hours must she work to meet her goals?
Answer:
42 hours
Step-by-step explanation:
Natalie needs to save a total of $479.58
She already saved $149.98
The amount left to save is
= 479.58-149.98
= 329.7
If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows
= 329.7 / 7.85
= 42
Hence Natalie will work for 42 hours to meet her goals

Angle a and angle b are complementary angles. The measure of ∠a is 42°.
Which equation represents this situation with x representing the measure of ∠b?
42−x=90
90+x=42
42+x=90
90+42=x
Answer:
42+x=90
Step-by-step explanation:
Complementary angles are when their measures add up to 90°
Therefore, if angle a is 42° you would find angle b by subtracting 42° from 90° which is shown in equation number three.

Victor and his cousin are playing a game where they pick up colored sticks. Victor currently has 26 points and likes to pick up the purple sticks, earning 7 points every turn. His cousin just lost all his points on the previous turn, and has a strategy to catch up by getting all the red ones, earning 20 points per turn. In a certain number of turns, the score will be tied. How many points will they each have? How long will that take?
Victor and his cousin will each have__ points in __turns.
Answer:
They each will have 20 points
it will take 2 turns
Victor and his cousin will each have 20 points in 2 turns
Step-by-step explanation:
let the number of turns it will take be x
In x turns, the number of points Victor will have is;
26 + 7(x) = 26 + 7x
In x turns, the number of points the cousin will have is:
20 * x = 20x
so we can get x from here;
20x = 26 + 7x
20x-7x = 26
13x = 26
x = 26/13
x = 2
In two turns, the number of points will be 20(2) = 40 points
It will take 2 turns
Victor and his cousin will each have 40 points in 2 turns

Daniel's print shop purchased a new printer for $35,000. Each year it depreciated at a rate of 5%. What will it's approximate value be at the end of the fourth year?
Answer:
28,000
Step-by-step explanation:
do 5% times 4% and you will get 20% and then change 20% to a decimal and multiply 0.20 times 35,000 and you should get 7000 then subtract 35,000 - 7000 and you should get 28,000
Answer:
$28,507.72
Step-by-step explanation:
y=35000 (1- .05)^4
y=35000 (.95)^4
y=35000(.81451)
y=28507
