Answer:
a) 23%
Step-by-step explanation:
To find the price change as percentage :
Multiply 100 by 160 then divide it by 130
100 × 160 ÷ 130 = 123 approximately which means there's an additional 23% to the 100% price
Answer:
The new position of the fish is = -23.05 feet
Step-by-step explanation:
We are being told that a fish is swimming 10.2 feet below the water surface
i.e. -10.2 feet
The fish then descend another 12.85 feet.
This means;
The first goes down from its first initial depth.
Mathematically, the subtraction expression that can be used to find the new position of the fish is:
= ( -10.2 + (-12.85) ) feet
Then, the new position of the fish is
= -23.05 feet
Answer:
a) R = 3.6
b) A = 2
Step-by-step explanation:
To find the value, start by modeling the inverse proportionality by using the base equations with the original givens.
y = k/x
12 = k/1.5
18 = k
Now we use that to model the equation
R = 18/A
And we can now use that to solve parts a) and b)
a)
R = 18/A
R = 18/5
R = 3.6
b)
R = 18/A
9 = 18/A
2 = A
Answer:
20 and 16
Step-by-step explanation:
Let us find x and y.
x – y = 4 _____(1)
x/2 + y/2= 18___(2)
Multiply (2) by 2 and add to (1)
x - y = 4
+<u>(x + y = 36)</u>
<u>2x = 40</u>
=> x = 40 / 2 = 20
From (1):
20 - y = 4
=> y = 20 - 4 = 16
The two numbers are 20 and 16.
If 12 pairs of socks sell for $5.79, then the unit rate is 12 : 5.79. If we want to find a unit rate for one pair of socks, we need to divide 5.79 by 12:
5.79 / 12 = 0,4825
So the unit rate is 1 : 0.4825
