57.4 millilitres
We know that the chemist has 332 milliliters of the solution of acid and water, and 17.3% of that solution is acid.
We can then persume that the amount of acid in the solution is equal to 332ml × 17.3%
This is equal to 57.436ml.
Then the question states to round the answer to the nearest tenth.
Rounding 57.436ml to the nearest tenth (.1) will equal to 57.4ml.
Therefore, there are 57.4ml of acid in the solution rounded to the nearest tenth.

is 5h +2h² = 7h a true statement? substitute a value other than 0 or 1 for h and evaluate 5h + 2h² and 7h to support your answer
Answer:
No it isn't a true statement
Step-by-step explanation:
I chose the Value 3 for it to be a true statement both sides would equal eachother
5×3+2×3²=7×3
5×3+2×9=21

Write the scale factors and values for x for the pairs of similar triangles below. 9 cm x cm 4 cm 2 cm Scale Scale Factor: X=
The scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.
Scale Factor of Similar TrianglesScale factor of similar triangles is the ratio of their corresponding sides.
Given the two similar triangles in the diagram attached below, we have the following scale factor as:
Scale factor = 2/4 = 1/2
Therefore:
x = 1/2 × 9
x = 4.5 cm.
Therefore, the scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.

Step-by-step explanation:
Firstly, notice that this shape is composed of ³/₄ of a circle and ¹/₂ of a square;
The lower left part is the ¹/₂ square, with only 2 sides (a left and lower side) of length 3 units;
The perimeter of this part of the shape is simply the sum of the two sides:
3 + 3 = 6
The remaining part is the ³/₄ circle, which has a radius of 3 units;
The circumference of a circle is found by the formula:
πd
d = diameter = 2 × radius
We only have ³/₄ of the circle, however, so we only have ³/₄ the circumference:
³/₄ × π(2(3)) = ³/₄ × 6π
= ⁹/₂π (or, equally, 4.5π)
So the total perimeter is the sum of the perimeter of the ¹/₂ square and the ³/₄ circle:
4.5π + 6
Find the domain and the range of the function
domain:
range:
Answer:
Approach 1: Mathematical Approach
Domain is the possible inputs or x values of a function
Here we can use any x values greater than or less than 7. We can also use 7 since their is a a function defined for x greater than or equal to 7.
So the domain is (-♾, ♾).
The range is possible y values. Since we can use negative x values, if we plug in x values for the function -5/7x+1, we are going to get positive numbers, as we plug in higher negative numbers, our range is bigger.
This means the range is bounded to -4 so our range is
(-4,♾)
Approach 2: Graphical Approach
Above is the graph
It can take any x values so the domain is (-♾, ♾).
The range is (-4,♾).

Golf Strokes An Internet site compares the strokes per round for two professional golfers. Which golfer is more consistent: Player A with mu = 71.5 strokes and o = 2.3 strokes, or Player B with mu 70.1 strokes and o = 1.2 strokes? Explain your reasoning.
Answer:
Player B
Step-by-step explanation:
Player B is more consistent because their sample standard deviation of [tex]\sigma=1.2[/tex] is less than that of Player A's sample standard deviation of [tex]\sigma=2.3[/tex], so it creates less variance from Player B's mean number of strokes and has more consistency.

Sumalee ran 34 miles more than Heather
last week. Sumalee ran 46 miles. How
many miles did Heather run?
Answer:
12 miles
Step-by-step explanation:
Since, Sumalee ran 34 miles more than Heather.
therefore
Distance run by Sumalee = Distance run by Heather + 34 miles
S = H + 34
But, S = 46 miles (given)
So, 46 = H + 34
H = 46 - 34
H = 12 miles
Distance run by Heather = 12 miles

But we can solve it through ratios if time is same
64/57.6=49/x1.12=49/xx=49/1.12x=$43.75Answer:
$44.10
Step-by-step explanation:
Method 1Given:
64 miles = $57.60To find the cost per mile, divide the total given cost by the given number of miles:
⇒ Cost per mile = $57.60 ÷ 64 = $0.90
To find the cost of a 49 mile tax ride, multiply the cost per mile by 49:
⇒ Cost of 49 mile tax ride = $0.90 × 49 = $44.10
Method 2We can use ratios of cost to miles to find the solution.
Let x = cost of a 49 mile taxi ride
[tex]\begin{aligned}\sf \$57.60:64 & = \sf x:49\\\sf \dfrac{57.6}{64} & =\sf \dfrac{x}{49}\\\sf 57.6(49) & = \sf 64x\\\sf 2822.4 & = \sf 64x\\ \sf x&= \sf \dfrac{2822.4}{64}\\ \sf x & = \sf \$44.10\end{aligned}[/tex]

(6, 2), (0, -2), (-3, -4)
Step-by-step explanation:
The intercepts are clearly (0, -2) and (3, 0). This eliminates the bottom two choices.
Both of these are listed in the upper left choice, but the third point there, (-6, -5), is not on the graph. This leaves only the upper right choice. Checking the remaining two points in that choice, (6, 2) and (-3, -4), confirms they are both on the graph.

20 9/11 divided by 6 19/20
Answer:
the exact answer is 2 1522/1529. sadly this cannot be simplified
Answer:
2 1522/1529 ≈ 2.995422
Step-by-step explanation:
Division of mixed numbers with different denominators is often best done by converting each to an improper fraction. Then, the division can be accomplished by multiplying the dividend by the reciprocal of the divisor.
20 9/11 = (20∙11 +9)/11 = 229/11
6 19/20 = (6∙20 +19)/20 = 139/20
The division problem then becomes ...
20 9/11 ÷ 6 19/20 = (229/11) × (20/139) = (229∙20)/(11∙139)
= 4580/1529 = 2 1522/1529

what is the value of
a.) J
b.) k
Answer:
j = 47
k = 7
Step-by-step explanation:
Hi there!
r = 9i-7
To find j, replace i with 6:
j = 9(6)-7
j = 54-7
j = 47
r = 9i-7
To find k, replace r with 56:
56 = 9k-7
63 = 9k
7 = k

Select the correct answer. A new airline airplanes with two different seating configurations and has a policy where customers are randomly assigned seats.
NO LINKS!!
Answer:
B. Configuration B has a higher probability of an aisle seat.
Step-by-step explanation:
Each configuration has the same number of seats in every row. That means we can determine the probability Dan will be assigned an aisle seat by considering only one row.
In configuration A, each row has 6 seats, of which 2 are aisle seats. The probability of being assigned an aisle seat is ...
p(aisle) = 2/6 = 1/3 . . . . configuration A
In configuration B, each row has 9 seats, of which 4 are aisle seats. The probability of being assigned an aisle seat is ...
p(aisle) = 4/9
Since 4/9 > 1/3, Dan should hope his flight uses configuration B.
