Guys please help do I multiply or divid & which number will I be diving w or multiply
Answer:
1. a) $24, b) $36, c) $48
2. a) $18, b) $27, c) $36
3. a) $1.64, b) $2.46, c) $3.28
5. a) $30, b) $50, c) $70
6. a) $4.05, b) $6.75, c) $10.80
7. a) $14.85, b) $24.75, c) $39.60
Explanations:
Whatever we multiply the item by, we multiply the cost by. If we double the number of socks, we double the price. If we triple the number of socks, we triple the price.
1. a) 3 costs $12, and 3 x 2 = 6, so we do the same to the price: $12 x 2 = $24
b) 3 times 3 is 9, so 3 x 12 gives you that cost, $36
c) 3 x 4 = 12, so 12 x 4 = $48
2. a) 3 pairs is $9, and we need 6 pairs. 3 x 2 = 6, so we also multiply the price x 2 = $18
b) 3 x 3 = 9 pairs, multiply the cost times 3 as well. 9 x 3 = $27
c) 3 x 4 = 12, multiply the cost x 4. 9 x 4 = 36
3. 4 apples cost $0.82
a) 4 x 2 = 8 apples, $0.82 x 2 = $1.64
b) 4 x 3 = 12 apples, $0.82 x 3 = $2.46
c) 4 x 4 = 16 apples, $0.82 x 4 = $3.28

Which symbol correctly compares the two angles? pi 3 \ 60^
Answer: =
Step-by-step explanation: just took the test
We will see that both angles are actually the same one (but in different units) so the symbol that we need to use is the equal symbol.
Which symbol correctly compares the two angles?
Here we have two angles, one in degrees and the other in radians, we want to compare them. To do it, we will need to write both of the angles in the same units.
The angles are:
pi/3 rads
60°
First, remember that:
pi rads = 180°
1 rad = (180°/pi)
With this, we can change the units of the first angle to get:
pi/3 rads = pi/3*(180°/pi) = 180°/3 = 60°
So both angles are actually the same angle, then the symbol that correctly compares them is the equal symbol.
pi/3 rads = 60°

Answer:
17÷50
Step-by-step explanation:
0.34
= 0.34/1
= (0.34 × 100) ÷ (1 × 100)
= 34/100

Answer:
[tex]\frac{s}{s-4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{s^2+6s}{s^2+10s+24}[/tex] ÷ [tex]\frac{s-4}{s+4}[/tex] ( factor and simplify fraction on left )
= [tex]\frac{s(s+6)}{(s+4)(s+6)}[/tex] ÷ [tex]\frac{s-4}{s+4}[/tex] ← cancel (s + 6) on numerator/ denominator
Leave first fraction, change division to multiplication, turn second fraction upside down
= [tex]\frac{s}{s+4}[/tex] × [tex]\frac{s+4}{s-4}[/tex] ← cancel (x + 4) on numerator/ denominator
= [tex]\frac{s}{s-4}[/tex]
To estimate the mean length of rattlesnakes, 10 such snakes are randomly selected. Their lengths, in inches, are as follows: 40.2 43.1 45.4 44.5 39.5 40.2 41.0 41.6 43.1 44.9 Find a 90% confidence interval for the mean length of all rattlesnakes.
Answer:
The confidence interval will be "41.04, 43.81".
Step-by-step explanation:
Given that,
Sample size,
n = 10
Sample total,
423.5
Sample mean,
[tex]\bar X =\frac{423.5}{10}[/tex]
[tex]=42.35[/tex]
Sample variance,
[tex]s = \sqrt{4.5894}[/tex]
[tex]=2.1423[/tex]
[tex]df=n-1[/tex]
[tex]=9[/tex]
[tex]t^*=18331[/tex]
Now,
The margin of error will be:
⇒ [tex]E=\frac{s\times t^*}{\sqrt{n} }[/tex]
[tex]=\frac{2.1423\times 1.8331}{\sqrt{9} }[/tex]
[tex]=\frac{3.928}{3 }[/tex]
[tex]=1.309[/tex]
hence,
The 90% confidence level will be:
= [tex](\bar X-E),(\bar X+E)[/tex]
By substituting the values, we get
= [tex](42.35-1.309),(42.35+1.309)[/tex]
= [tex](41.04),(43.81)[/tex]

|x-4| if x>4
can you please help me
Answer: x - 4 without the absolute value bars surrounding it
=================================================
Explanation:
If x is larger than 4, then x-4 is positive. For example, if x = 5, then
x-4 = 5-4 = 1
So for cases when x > 4, the |x-4| and x-4 are the same identical expression. Try out more values of x to compare the two outputs. I recommend making a table with 3 columns. You'll have x in column 1, then |x-4| in column 2, and x-4 in column 3. You should find that the outputs for columns 2 and 3 are identical when x is larger than 4.
It's only when x < 4 is when |x-4| and x-4 differ. Instead we would say |x-4| = -(x-4). But we aren't focused on this case.
In short, when x > 4, we simply drop the absolute value bars to get the answer x - 4

needs to be raked?
Answer:
Step-by-step explanation:
The raked portion is 5/12 plus 4/9, or (applying the LCD, 36),
20/36 + 24/36.
The sum of these two fractions is 44/36, or 1/9.
1/9 of the yard remains to be raked.
