Answer:
Step-by-step explanation:
Let amount of water in lbs is x
so, mass of solution = mass of water + mass of sugar
= (x + 0.5) lbs
concentration of syrup = mass of sugar/mass of solution × 100
75 = 0.5/(x + 0.5) × 100
or, 75/100 = 0.5/(x + 0.5)
or, 3/4 = 0.5/(x + 0.5)
or, 3x + 3 × 0.5 = 4 × 0.5
or, 3x + 1.5 = 2
or, 3x = 0.5
or, x = 0.167 lbs
hence, amount of water is 0.167 lbs
Answer:
0.167lbs

Which graph shows a line with the slope of 3/2?
Answer:
B.
Step-by-step explanation:
slope = Rise (y difference) / Run (x difference)
B, Rise = 3 run = 2 slope = 3/2
The graph with a line of slope 3/2 is graph B.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Slope of a line with two points (x, y) and (x', y') on the lines is,
Slope = (y' - y) / (x' - x)
Take any two points from all the three graphs given to find the slope.
A. Two points are (0, 4) and (6, 8)
Slope = (8 - 4) / (6 - 0) = 4 / 6 = 2/3
B. Two points are (0, 0) and (4, 6)
Slope = (6 - 0) / (4 - 0) = 6/4 = 3/2
C. Two points are (0, 2) and (2, 8)
Slope = (8 - 2) / (2 - 0) = 6/2 = 3
Hence the graph B has slope equals 3/2.

Determine what shape is formed for the given coordinates for ABCD, and then find the perimeter and area as an exact value and rounded to the nearest tenth.
A (−9, 3), B (−6, −1), C (2, 5), D (−5, 6)
Answer:
Perimeter = 5 + 5 + 7.1 + 10 =27.1
area = (5 + 10)x5 / 2 = 37.5
Step-by-step explanation:
Slope formula: m = (x' - x)/(y' - y)
m-AD: (6-3)/(-5 - -9) = 3/4 (I'm not detail other Other slopes)
m- BC = 3/4
m-AB = - 4/3
m-AD = m-BC AD // BC (ABCD is a Trapezoid)
m-AB = - 1 / m-BC
AB ⊥ BC
segment length formula: d = √(x' - x)² + (y' - y)²
AD = √(-5 - -9)² + (6 - 3)² = √4² + 3² = √25 = 5
DC = √50 = 7.1
BC = √100 = 10
AB = √25 = 5
Perimeter = 5 + 5 + 7.1 + 10 =27.1
area = (5 + 10)x5 / 2 = 37.5
area ABCD = (5+10)x5 / 2 =

tan(A/2)
tan(A/2)=sinA/1+cos A
tan(A/2)= 5/13÷1+12/13
tanA/2=1/5
Answer:
tan([tex]\frac{A}{2}[/tex] ) = ± [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Using the trigonometric identity
tan ([tex]\frac{A}{2}[/tex] ) = ± [tex]\sqrt{\frac{1-cosA}{1+cosA} }[/tex]
Given
tanA = [tex]\frac{5}{12}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle 5- 12- 13 ( with hypotenuse 13 ), then
cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{13}[/tex] , then
tan ([tex]\frac{A}{2}[/tex] )
= ± [tex]\sqrt{\frac{1-\frac{12}{13} }{1+\frac{12}{13} } }[/tex]
= ± [tex]\sqrt{\frac{\frac{1}{13} }{\frac{25}{13} } }[/tex]
= ± [tex]\sqrt{\frac{1}{25} }[/tex]
= ± [tex]\frac{1}{5}[/tex]

33. 33 = 331 – 25
B
33.: + 33 = 33. - 25
33.25 = 33r - 25
332 + 25 = 33r - 25
Which is no solution
Answer:
A, B & D
Step-by-step explanation:
Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.
33x-33= 33x + 25
33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.
33x+33=33x+25
33x+8= 33x nope no solution
33x+25=33x+25
33x = 33x both sides identical so there is a solution
33x-25 = 33x +25
33x= 33x+50

Question: Determine The Value Of X.
9514 1404 393
Answer:
x = 78
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so the sum of angles is ...
x° +x° +24° = 180°
2x +24 = 180 . . . . . collect terms
x + 12 = 90 . . . . . . . divide by 2
x = 90 -12 . . . . . . . . subtract 12
x = 78
_____
Additional comment
The base angle of an isosceles triangle is always the complement of half the third angle. That angle's bisector is an altitude, so divides the isosceles triangle into two congruent right triangles.
Is Noah's work correct? Explain. Yes, Noah's calculations are correct. No, Noah did not simplify correctly. No, Noah used the diameter instead of the radius in the calculations. No, Noah did not use the correct formula for volume of a sphere.
Answer:
No, Noah used the diameter instead of the radius in the calculations.
V = 91.13π
Step-by-step explanation:
Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.
V = πr3
V = π(9)3
V = π(729)
V = 972π cubic units
Is Noah’s work correct
Volume of a sphere, V = πr³
radius, r = diameter / 2
Diameter = 9 units
r = 9 / 2
= 4.5 units
Volume of a sphere, V = πr³
= π × 4.5³
= π × 91.125
= 91.125π
Approximately 91.13π
V = 91.13π
No, Noah used the diameter instead of the radius in the calculations.
Answer:
no, he used radius instead of diameter

Tim is reading a book. On Monday he reads 2 pages. On each day after that, he reads triple the number of pages as the previous day. How many pages did Tim read on Thursday?
Answer:
Tim read 54 pages on Thursday.
Step-by-step explanation:
Consider the provided information.
Tim read 2 pages on Monday. Each day after that, he reads triple the number of pages as the previous day.
Monday = [tex]2=2[/tex]
Tuesday = [tex]2\times 3=6[/tex]
Wednesday = [tex]2\times 3\times 3=18[/tex]
Thursday = [tex]2\times 3\times 3\times 3=54[/tex]
Hence, Tim read 54 pages on Thursday.
How many pages does Tim read on Monday? 2 pages.
If Tim tripled the amount that he read on Monday, how many pages did he read on Tuesday? 2 × 3 = 6 Pages
Repeat for Wednesday. 6 × 3 = 18 Pages
Repeat for Thursday. 18 × 3 = 54 Pages
