You need a 40\% alcohol solution. On hand, you have a 150 mL of a 20% alcohol mixture. You also have 55% alcohol mixture. How much of the 55% mixture will you need to add to obtain the desired solution?
Answers
Answer:
You need to add 200 mL of the 55% to obtain the desired solution
Step-by-step explanation:
x=mixture you need to add
20% * 150 + 55% x = 40%(x + 150)
0.20 * 150 + 0.55x = 0.40(x + 150)
30+0.55x=60+0.40x
0.15x = 30
x=200 mL
The slope of a line is -1/3. Find the slope of a line that is perpendicular to this line.
Answers
Answer: 3
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of each other.
Answer:
Slope = 3
Step-by-step explanation:
The question is asking us to find the slope of the line that is perpendicular to the line whose slope is -1/3.
Main idea: Perpendicular lines have slopes that are opposite reciprocals.
So our task boils down to finding the opposite reciprocal of -1/3.
First, we change the sign from negative to positive. We get 1/3.
Then, we turn the number over. We get 3.
Therefore, the slope is 3.

What did is the total volume,in cubic feet of the shape below
Answers
Answer:
64ft^3 (The ^3 is meant to be cubed) 64 feet cubed.
Step-by-step explanation:
The picture has already split the two shapes.
*Remember Volume Formula: LWH or Length times Width times Height.*
The first shape is 4ft x 2ft x 2ft
The second shape is a little bit of a fuss but it's alright.
*Talking about the length of Shape no.2*
Since the second shape is longer than the first one (by length). You need to double it meaning: 4x2 or 4+4 = 8ft
The second shape is 8ft x 2ft x 3ft
First shape should have a volume of 16ft
Second shape should have a volume of 48ft
Now, you need to add the two volumes:
48ft + 16ft = 64ft cubed

Two chords PQ and ST of length 6cm and 10cm respectively of a circle are parallel to each other and are on opposite side of its center. If the distance between PQ and ST is 5cm. Find the radius of the circle
Answers
Answer:
Draw two parallel chords AB and CD of lengths 5 cm and 11 cm. Let the center of the circle be O. Join one end of each chord to the center.
Draw two perpendiculars OM and ON to AB and CD, respectively, which bisects the chords.
Two chords AB and CD of lengths 5 cm and 11 cm respectively of a circle are parallel to each other and are on opposite sides of its center. If the distance between AB and CD is 6 cm, find the radius of the circle.
Thus, MB = 2.5 cm and ND = 5.5 cm [The perpendicular drawn from the center of the circle to the chords bisects it.]
Let OM = x and ON = 6 - x
Consider ΔOMB
By Pythagoras theorem,
OM2 + MB2 = OB2
x2 + 2.52 = OB2
x2 + 6.25 = OB2..................(1)
Consider ΔOND
By Pythagoras theorem,
ON2 + ND2 = OD2
(6 - x)² + 5.52 = OD2
36 + x2 - 12x + 30.25 = OD2
x2 - 12x + 66.25 = OD2............... (2)
OB and OD are the radii of the circle. Therefore OB = OD.
Thus, OB2 = OD2
Equating (1) and (2) we get,
x2 + 6.25 = x2 - 12x + 66.25
12x = 60
x = 5
Substituting the value of x in (1),
OB2 = x2 + 6.25
OB2 = 52 + 6.25
OB2 = 31.25
OB = 5.59 (approx.)
Thus, we get the radius of the circle = 5.59 cm.

6) you have now got the square root of 784 and you can now simplify the denominator to 28
7) your equation should be Z= -1 multiplied by the square root of 28 over 28

Find the next two numbers in the sequence 5,2,-1,…
Answers
Answer:
The answer is (-4) and (-7).
Step-by-step explanation:
Given;a₁ = 5a₂ = 2a₃ = (-1)To Find;a₄ = ?a₅ = ?Formula;aₙ = a + (n – 1) × dNow, for common difference (d)
d = a₂ – a₁ = 2 – 5 = -3
d = a₃ – a₂ = (-1) – 2 = -3
Here, common difference is same everywhere.
So, for fourth term or n = 4
aₙ = a + (n – 1) × d
a₄ = 5 + (4 – 1) × (-3)
a₄ = 5 + 3 × (-3)
a₄ = 5 – 9
a₄ = -4
Then, for fifth term or n = 5
a₅ = 5 + (5 – 1) × (-3)
a₅ = 5 + 4 × (-3)
a₅ = 5 – 12
a₅ = -7
Thus, The fourth term is (-4) and fifth term is (-7).
