In the Tide Pool tank at the Atlantic Aquarium, there are 10 crustaceans and 25 fish. The Deep Blue tank has the same ratio of crustaceans to fish. There are 50 crustaceans in the Deep Blue tank. How many fish are in the Deep Blue tank?
PLZ HELP
Answers
Answer:
125 fish
Step-by-step explanation:
The Tide Pool has 10 crustaceans and 25 fish. So, simplified, for every 2 crustaceans there are 5 fish. That also means, the amount of crustaceans is 2/5 of the amount of fish.
Deep Blue has 50 crustaceans. That is 2/5 of how many fish are in the tank. Multiply 50 by 5/2 to get the amount of fish.
(50 * 5)/2
250/2
There are 125 fish in the Deep Blue tank.

the function f is defined by f(x)=150/x-z where z is a constant. find z if the value of f at x=1/5 is equal to 250
Answers
Answer:
z=500
Step-by-step explanation:
since we know that the whole equation is equal to 250, we can substitute values in.
250=150/1/5 -z
250=750-z
-500=-z
z=500
The value of z for the function f(x)=150/x-z is z=500.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the function f is defined by f(x)=150/x-z where z is a constant. The value of the function at x = 1/5 is 250.
The value of the constant z will be calculated as,
The whole equation is equal to 250, we can substitute values in.
250=150/1/5 -z
Simplify the equation and solve for the value of z,
250=750-z

Taliyah has 174 coins in her collection of dimes and nickels. The total value of the collection is $15.20. How many dimes does she have in her collection?
Answers
Answer:
130 dimes
Step-by-step explanation:
A nickel is worth 5 cents = 0.05n
A dime is worth 10 cents = 0.10d
Taliyah has 174 coins in her collection of dimes and nickels.
n + d = 174
n = 174 - d
The total value of the collection is $15.20.
0.05n + 0.10d = $15.20
We substitute 174 - d for n
Hence:
0.05(174 - d) + 0.10d = 15.20
8.7 - 0.05d + 0.10d = 15.20
- 0.05d + 0.10d = 15.20 - 8.7
0.05d = 6.5
d = 65/0.05
d = 130 dimes
The number of dimes she has in her collection is 130 dimes
The perimeter of a rectangular lawn is 80m. If the length had been 2m less and breadth
2m more, the lawn would have been a square. Find the dimensions of the lawn.
?
Answers
Answer:
The dimensions of the lawn are 22 m and 18 m
Step-by-step explanation:
Let us solve the question
Let the length of the rectangular lawn is x m and its breadth is y m
∵ The length of the lawn = x meters
∵ The breadth of the lawn = y meters
∵ Its perimeter = 80 meters
→ The formula of the perimeter is P = 2(length + breadth)
∴ 2(Length + breadth) = 80
→ Substitute the length by x and the breadth by y
∴ 2(x + y) = 80
→ Divide both sides by 2
∵ (x + y) = 40
∴ x + y = 40 ⇒ (1)
∵ The length had been 2 m less
∴ The new length = x - 2 meters
∵ breadth had been 2 m more
∴ The new breadth = y + 2 meters
∵ The lawn would have been a square
→ The square has equal sides, then equate the new length and breadth
∴ x - 2 = y + 2
→ Add 2 to both sides
∵ x - 2 + 2 = y + 2 + 2
∴ x = y + 4 ⇒ (2)
→ Substitute x in equation (1) by equation (2)
∵ y + 4 + y = 40
→ Add the like terms
∴ 2y + 4 = 40
→ Subtract 4 from both sides
∵ 2y + 4 - 4 = 40 - 4
∴ 2y = 36
→ Divide both sides by 2
∴ y = 18
→ Substitute y by 18 in equation (2) to find x
∵ x = 18 + 4
∴ x = 22
∴ The dimensions of the lawn are 22 m and 18 m
32 + 24 = 55 ( + ) Write 32 + 23 as a product of the two factors using the GCF and the distributive property.
Answers
The right presentation of the question is:
(a) Write 32 + 24 as a product of the two factors using the GCF and the distributive property.
(b) Write 32 + 23 as a product of the two factors using the GCF and the distributive property.
Answer:
[tex](a)\ 32 + 24 = 8*7[/tex]
[tex](b)\ 32 + 23 = 5*11[/tex]
Step-by-step explanation:
Solving (a):
First, we take the GCF of 32 and 24
[tex]32 = 2 * 2 * 2 * 2 * 2[/tex]
[tex]24 = 2 * 2 * 2 * 3[/tex]
Take common factors:
[tex]GCF = 2 * 2 * 2[/tex]
[tex]GCF = 8[/tex]
So, we factorize 32 and 24 using 8.
The expression becomes:
[tex]32 + 24 = 8(4 + 3)[/tex]
Simplify the expression in bracket
[tex]32 + 24 = 8(7)[/tex]
Remove bracket
[tex]32 + 24 = 8*7[/tex]
--------------------------------------------------------------------------------------------------
Solving (b):
[tex]32 + 23 =[/tex]
32 and 23 do not have a common factor, so we have to start by writing 32 as 30 + 2
[tex]32 + 23 = 30 + 2 + 23[/tex]
Add 2 to 23
[tex]32 + 23 = 30 + 25[/tex]
Take the GCF of 30 and 25
[tex]30 = 2 * 3 * 5[/tex]
[tex]25 = 5 * 5[/tex]
Take common factors:
[tex]GCF = 5[/tex]
So, we factorize 30 and 25 using 5.
[tex]32 + 23 = 5(6 + 5)[/tex]
Simplify the expression in bracket
[tex]32 + 23 = 5(11)[/tex]
Remove bracket
[tex]32 + 23 = 5*11[/tex]
b) The distance between two places is 18 km. If the map scale is 1:400000, find the
distance between the places in centimetres drawn in the map.
Answers
Answer:
Map scale is 1:400000 => 1 cm on the map represents 400000 cm (4 km) on the ground.
So, 18 km on the ground is represented by 18/4 cm or 4.5 cm on the map.
Answer: 4.5 cm
Step-by-step explanation:
The clear and easiest way to deal with this problem is to convert all measurements to centimeters because that is the stated unit to be used. In SI, the metric prefixes can be written as exponents. The prefix kilo corresponds to 10^3 while the prefix centi corresponds to 10^-2 so 18 km = 18 x 10^3 m = 18 x 10^3 x 10^2 cm= 18 x 10^5 cm.
The number 18 x 10^5 cm is to be reduced to 400,000 times in the map and it means a process of division is to be performed. Dividing 18 x 10^5 cm by 400,000 gives a quotient of 4.5 cm.
This means that an actual distance of 18 km, on the map it just corresponds to 4.5 cm distance if the scale used is 1:400,000.

Lamont Gatling purchased a phone answering system for his home office. The list price was $99.86. He also purchased a 12-foot handset cord for $8.95 and 50 feet telephone wire for 45¢ per foot. He received a $5.00 rebate on the phone system and had a store coupon for $1.00 off each accessory. If he paid a 6 percent sales tax on the final price, how much did he pay?
Answers
Answer:
$130.7086
Step-by-step explanation:
List price of phone answering system = $99.86
Handset cord = $8.95
Telephone wire = 45 cent/foot ; length = 50 feet
Rebate on phone system = $5
Store coupon =$1 of each accessory
Sales tax = 6% on final price
Price before coupon = (99.86 + 8.95 + (50*0.45)) =$131. 31
Number of accessories = 3
Total coupon = $5 + ($1 * 3) = $8
Price after coupon = final price : $131.31 - $8 = $123.31
Sales tax = 0.06 * $123.31 = $7.3986
Amount paid = $123.31 + $7.3986 = $130.7086
Greg made $253 for 11 hours of work. At the same rate, how much would he make for 18 hours of work?
Answers
Answer:
$414
Step-by-step explanation:
Let's start by figuring out how much he earns per hour.
253/11=23
Greg earns $23 per hour. So if he worked for 18 hours, he would make $414.
Answer:
$414
Step-by-step explanation:
First, we have to find the unit rate, so our first equation is:
253 ÷ 11 = 23
So Greg gets $23 an hour
So for 18 hours our equation is:
23 x 18 = 414
So Greg would make $414 if he worked for 18 hours
-2y + 6 = -12 lol how do i solve that again??
Answers
Answer:
y=9
Step-by-step explanation:
-2y + 6 = -12
-2y - 6 = -6
-2y = -18
-2/y= -18/-2
y= 9
You need to subtract six one both sides first, that will cancel out the positive six, and that will also give you this:
-2y = -18
Now, divide negative two on both sides, that will cancel out both the negative signs, and it will also cancel out the two and it will give you your final answer:
y = 9
