The acidity in a swimming pool is considered
normal if the average of three pH readings, p, is
defined such that 7.0
Answer:
6.2
Step-by-step explanation:
[tex] \frac{7.2 + 7.6 + x}{3} = 7.0 \\ \frac{14.8 + x}{3} = 7.0 \\ 14.8 + x = 21 \\ x = 21 - 14.8 \\ x = 6.2[/tex]

Answer:
X=22° ; Exterior Angle = 125°
Step-by-step explanation:
The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.
(2x) + (103 - x) = (6x - 7)
103 + 7 = 6x - 2x + x
110 = 5x -->(Divided by 5)--> x=22°
6(22) - 7 = 125°

Jose needs 6.2 lb of organic blueberries to make smoothies. Organic blueberries are on sale for $2.85 per pound. Jose estimates that he will need $12 to buy the 6.2 lb of blueberries. What is Jose’s error?
1. Jose did not make an error. His estimate of $12 is correct.
2. Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
3. Jose incorrectly rounded 6.2 up to 7.
4. Jose incorrectly multiplied 2 and 7. The estimate should be $14.

B
Step-by-step explanation:
Write an equation of the line that passes through the point (4, –5) with slope 2.
Answer:
y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
Answer:
y + 5 = 2(x−4)
Step-by-step explanation:
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
subtract 8 on both sides
-13 = b

Tom makes $264.00 in 5 days. How much does he make in 2 days?
Answer:
$105.6
Step-by-step explanation:
Tom makes 264 in 5 days.
In one day he makes 52.8.
In two days he makes 105.6.
Answer:
Tom makes $105.60 in 2 days
Step-by-step explanation:
x(5) = $264
Divide both sides by 5: x = 52.8
We get how much he makes in a day.
Multiply by 2: $52.8 * 2
Final answer: $105.6

Consider the end behavior of the function g(x)=-1/3|x|+9 and complete the statements.
As x approaches negative infinity, g(x) approaches [ Negative, Positive ] infinity.
As x approaches positive infinity, g(x) approaches [ Negative, Positive ] infinity.
Answer: thanks for this answer, I was working on this problem.
As x approaches negative infinity, g(x) approaches [ Negative] infinity.
As x approaches positive infinity, g(x) approaches [ Negative] infinity.

Correct answer: [tex]b = \frac{2A}{h}[/tex], first option.
[tex]A=\frac{bh}{2}[/tex]
[tex]2*A=\frac{bh}{2}*2[/tex] | multiply both sides by 2, 2's cancel out on the right.
[tex]2A=bh[/tex]
[tex]\frac{2A}{h} =\frac{bh}{h}[/tex] | divide h on both sides, h's cancel out on the right
[tex]b = \frac{2A}{h}[/tex]
Can anyone help me about question 2
9514 1404 393
Answer:
3(4/3)^2543
Step-by-step explanation:
Using logarithms base 2, we have ...
[tex](a_n)^{\log{a_n}}=(a_{n+1})^{\log{a_{n-1}}}\\\\(\log{a_n})(\log{a_n}) = (\log{a_{n-1}})(\log{a_{n+1}}) \\\\ \dfrac{\log{a_{n+1}}}{\log{a_{n}}}=\dfrac{\log{a_n}}{\log{a_{n-1}}}=\dots\dfrac{\log_2{16}}{\log_2{8}}=\dfrac{4}{3}[/tex]
That is, the ratio of each term to the previous is a constant equal to 4/3. This is the definition of a geometric sequence. This sequence has first term 3 and common ratio 4/3, so the general term is ...
[tex]\log_2 a_n=3\left(\dfrac{4}{3}\right)^{n-1}[/tex]
and the 2544th term is ...
[tex]\boxed{\log_2{a_{2544}}=3\left(\dfrac{4}{3}\right)^{2543}}[/tex]

Answer:
1/3
Step-by-step explanation:
1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!
[tex]3 * \frac{1}{3} = \frac{3}{3} = 1[/tex] [tex]6 * \frac{1}{3} = \frac{6}{3} = 2[/tex] [tex]12 * \frac{1}{3}= \frac{12}{3}=4[/tex] [tex]15*\frac{1}{3}=\frac{15}{3} =5[/tex]2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.
can anyone help me with this, with a full explanation ?? thank you
Step-by-step explanation:
let the 3 consecutive odd number be
x + 1 , x + 3 , x + 5
as, there sum is 45. so, after inserting the values we got,
→ x + x + 1 + x + 3 = 45
→ 3x + 9 = 45
→ 3x = 45 - 9 = 36
→ x = 36/3 = 12
→ x = 12
therefore, 3 consecutive odd number are
→ x + 1 = 12 + 1 = 13
→ x + 3 = 12 + 3 = 15
→ x + 5 = 12 + 5 = 17
hope this answer helps you dear...take care and may u have a great day ahead!
If I was to sketch the graph of y=4x+2
What would the graph look like?
Would it be a straight line or a curved line?
Where would it cross the y-axis?
What does 4 in 4x tell us?
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 2 ← is in slope- intercept form
Thus its graph is a straight line
crosses the y- axis at (0, 2 ) , that is c = 2
the 4 in 4x is the slope m of the line
