Hassan originally had 200 goldfish
Step-by-step explanation:
Multiply 60 by 100, which will get you 6,000, then divide by 30 to get 200. The 100 is for the total percentage, the 30 is the percentage left.
Answer:
200goldfish
Step-by-step explanation:
since 30percent(100_70)is60 what about 100percent
100percent/30percent multiplied by 60goldfish=200
Therefore the answer is 200goldfish

Total surface area:
A = 4(1/2*7*l) + 7² = 14l + 49, where l is a slant heightWe are given:
A = 161 cm²Find the value of l:
14l + 49 = 16114l = 112l = 112/14l = 8 cmUse Pythagorean to find the height h of the pyramid:
l² = h² + (7/2)²8² = h² + 3.5²h² = 8² - 3.5²h² = 51.75h = √51.75h ≈ 7.2 cmFind the volume:

I need a little help with trigonometric ratios. What is the ratio to find x? Please provide an explanation to get brainliest.
Answer:
tan 72 = 6/x
OR
cos 72 = x/15
Step-by-step explanation:
A good way to remember trig ratios is this
SOH CAH TOA -
sin = opp/hyp
cos = adj/hyp
tan = opp/adj
You can find x in a few different ways.
If you did tangent, it would be
tan 72 = 6/x (because tangent is opposite over adjacent)
Or, there's also the pythagorean theorem...

Peter is 1.64 metres tall.
Peter is 18 centimetres taller than Nick.
San
Work out Nick's height in metres.
Answer:
the height of nick is 1.46
Step-by-step explanation:
because to change cm into m we need to divide it by 100so 18/100is 0.18
and total height of Peter is 1.64 so if we -the 0.18then we can get nick's height
Answer:
1.46
Step-by-step explanation:
1.64 to cm is 164
164-18 = 146
146 to meters is 1.46

Which of the following is NOT a solution to this system of inequalities?
with examples
Nonsense = report
Answer: Choice D. (0,-2)
Note how this point is in the blue region, but it is not in the red region. The solution must satisfy all of the shaded regions of the system of inequalities. The red and blue regions overlap to form the darker shaded region on the right side (the somewhat grayish purple triangular region). Points in this darkest shaded region are solutions to the system. The points (5,2), (0,3) and (4,0) are all located in this region so they are solutions.

Step-by-step explanation:
Raffle tickets are being sold for a fundraiser. The function a(n) relates the
amount of money raised to the number of tickets sold, n.
It takes as input the number of tickets sold and returns as output the amount
of money raised.
a(n) = 3n - 30
Which equation represents the inverse function n(a), which takes the money
raised as input and returns the number of tickets sold as output?
The money raised depends only on the number of tickets sold, the inverse equation is found by making the tickets sold the subject.
[tex] \underline {n =\frac{a(n) }{3} + 10}[/tex]
How can the inverse function be found?The given parameters are;
a(n) = The amount of money raised
n = The number of tickets sold
a(n) = 3•n - 30
Solution;
The equation that takes the amount of money raised and returns the number of tickets sold is found as follows;
a(n) = 3•n - 30
a(n) + 30 = 3•n
Therefore;
[tex]n = \frac{a(n) + 30}{3} = \frac{a(n) }{3} + 10[/tex]
The number of tickets sold,
[tex] \underline {n =\frac{a(n) }{3} + 10}[/tex]

Manny has 48 feet of wood. He wants to use all of it to create a border around a garden. The equation 2 l plus 2 w equals 48 can be used to find the length and width of the garden, where l is the length and w is the width of the garden. If Manny makes the garden 15 feet long, how wide should the garden be?
9 feet
18 feet
30 feet
33 feet
Answer:
Step-by-step explanation:
The Width of the garden will be 9 feet.
Step-by-step explanation:
Given:
Manny has wood =48 feet
Length of the garden = 15 feet
The equation which can be used .
We need to find the width of the garden.
Solution :
Now Length of the garden is given we will substitute in the given equation to find the width.
Now Using Subtraction property we will subtract both side by 30 we get;
Now Using Division Property we will divide both side by 2 we get;
Hence the Width of the garden will be 9 feet.
