At a middle school, 74 students have freckles. There are 258 students in the school. To the nearest tenth of a percent, what percent of the students have freckles?
Answers
And 74 kids have freckles, so we have to find the % of those kids with freckles.
258–100%
74-?%
Let’s find 1% of the kids.
258/100=2.58
Now let’s find the % of 74 kids.
74/2.58=28.68%~28.7%
(The percent of the kids with freckles is 28.7%)

Tan(270 ) = sin(270) / cos(270) = -sin(90) / cos(90) so now we know that Tan(270) is one of the non-existant angles b/c cos(90) = 0 and that would mean that we have some number over 0... and then the universe blows up.. like my calc II professor liked to say :| I think he was being a bit dramatic. :P anyway, you want answers not long boring stories.. :D so Tan(270) DNE ( does not exist )
If we were to look at a graph of Tan , we'd see that at 270° or 3[tex]\pi[/tex]/2 , Tan runs off to infinity. So there isn't a number to represent it. :/ I'm attaching a picture of the graph
notice in the graph, that when tan gets to 3/2, it's running off to infinity ??

Given:
Length of the cuboid tank = 4 m
Breadth = 2.5 m
Height = 2.4 m
One third of the tank is filled with water.
1 cubic meter = 1000 liters.
To find:
The quantity of the water in the tank.
Solution:
Volume of a cuboid is:
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth and h is the height.
The volume of the tank is :
[tex]V=4\times 2.5\times 2.4[/tex]
[tex]V=24[/tex]
Volume of tank is 24 cubic meter.
One third of the tank is filled with water. So, the volume of the water is
[tex]\dfrac{24}{3}=8[/tex]
The volume of water is 8 cubic meters.
We have,
1 cubic meter = 1000 liters.
8 cubic meter = 8000 liters.
Therefore, the quantity of the water in the tank is 8000 liters.

total tagged: 305
Answers
Answer:
Step-by-step explanation:
Step 1. (The capture) Capture a sample total counted =958, and them back tagged counted=38,total tagged=56
The idea is to estimate the proportion p = m/N of tagged =102.
Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.
It is reasonable that, k/n would be a good estimante for p = m/N.
Accordingly, for an estimate N of N, se solve the equation m/N= k/n.

X + 550
Answers
Answer:
x=65°
Step-by-step explanation:
Since all exterior angles add up to 360°.
⇒(3x+25°) + (20°) + (x+55°) =360°
⇒4x+100°=360° {Add up like terms}
⇒4x=260° {Subtract 100 from both sides}
∴ x=65° {Isolate x (divide both sides by 4)}

Answer:
Surface area of square pyramid = 380 m²
Step-by-step explanation:
Given:
Side of square base =10 m
Height of Square pyramid = 14 m
Find:
Surface area of square pyramid
Computation:
Surface area of square pyramid = Surface area of Base + 4[Surface area of triangle]
Surface area of square pyramid = [side x side] + 4[(1/2)(b)(h)]
Surface area of square pyramid = [10 x 10] + 4[(1/2)(10)(14)]
Surface area of square pyramid = 100 + 4[70]
Surface area of square pyramid = 100 + 280
Surface area of square pyramid = 380 m²

Answers
Answer:
see explanation
Step-by-step explanation:
The zeros of the graph are x = - 4 and x = 2 , then the factors are
(x + 4)(x - 2) and
y = a(x + 4)(x - 2) ← a is a multiplier
To find a use any other point on the graph and substitute into the equation
Using (0, - 8 ) , then
- 8 = a(4)(- 2) = - 8a ( divide both sides by - 8 )
1 = a
y = (x + 4)(x - 2) = x² + 2x - 8
with b = 2 and c = - 8
