Answer:
Tiffany's nectar is more sugary
Step-by-step explanation:
Given
Ramon:
[tex]Water = 8\ cups[/tex]
[tex]Sugar = 2\ cups[/tex]
Tiffany
[tex]Water = 9\ cups[/tex]
[tex]Sugar = 3\ cups[/tex]
Required
The nectar with more sugar
To do this, we simply calculate the fraction of sugar in both nectar.
This is calculated as:
[tex]Fraction = \frac{Sugar}{Sugar + Water}[/tex]
For Ramon:
[tex]Fraction = \frac{2}{8 + 2}[/tex]
[tex]Fraction = \frac{2}{10} = 0.20[/tex]
For Tiffany
[tex]Fraction = \frac{3}{3 + 9}[/tex]
[tex]Fraction = \frac{3}{12} = 0.25[/tex]
From the calculations above:
[tex]0.25 > 0.20[/tex]
Hence: Tiffany's nectar is more sugary
Johnny uses a mirror placed on level ground to measure the height of a building. Johnny's eyes are 6 feet above the ground and he stands 4 feet away from the mirror. From that distance, Johnny is able to see the top of the building in the mirror as shown in the diagram below.
If the mirror is 45 feet away from the building’s base, how tall is the building
please show step by step
Answer:
Step-by-step explanation:
θ = angle of incidence = angle of reflection
You have two similar triangles.
tanθ = 6/4 = h/45
h = 45×6/4 = 67.5 ft
The required height of the building is 67.5 feet.
Johnny uses a mirror placed on level ground to measure the height of a building. Johnny's eyes are 6 feet above the ground and he stands 4 feet away from the mirror. If the mirror is 45 feet away from the building’s base, how tall the building is determined.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Since the two triangles are similar,
Let the height of the building is x.
The ratio of height and distance from the mirror Jhonny = height and distance of mirror from the building.
6/4=x/45
x = 11.25*6
x = 67.5
Thus, the required height of the building is 67.5 feet.

I need help with part b and c, I did a already
Answer:
a) V = 35.1 in.^3
b) V = 288 pi in.^3
c) h = 2.7 in.
Step-by-step explanation:
a)
radius of base = 2 in.
height = 8 in.
volume of cone = (1/3)(pi)(r^2)h
V = (1/3)(pi)(2 in.)^2(8 in.)
V = 35.1 in.^3
You are correct.
b)
You must leave the answer in terms of pi, so do not use 3.14 or another approximation for pi.
radius of base = 6 in.
height = 24 in.
volume of cylinder = (pi)(r^2)h
V = (1/3)(pi)(6 in.)^2(24 in.)
V = 288 pi in.^3
c)
volume = 288 pi in.^3
radius = 18 in.
288 pi in.^3 = (1/3)(pi)(18 in)^2 h
288 in. = (1/3)(324)h
288 in. = 108h
h = 2.666 in.
h = 2.7 in.
One interior angle of a triangle is 30⁰. The other angle measures are x⁰ and y⁰. Which of the following could be the values of x and y? Select ALL that apply
Step-by-step explanation:
One interior angle of a triangle = 30⁰ .
The measure of other two are x and y .
We know that the angle sum property of a triangle is 180⁰ .
=> x + y + 30⁰ = 180⁰
=> x + y = 180⁰ - 30⁰.
=> x + y = 150⁰.
Possible solution set of x and y are ,
(1,149) (2,148 ) ...... (148+2) & (149+1)
Basically we are here decreasing y and increasing x to obtain the values .

the area of a rectangle knitted blanket is 9x^2-6x-8. What are the possible dimensions of the blanket? Use factoring
Answer:
3x+2 and 3x-4
Step-by-step explanation:
We are given the quadratic equation 9x²-6x-8.
first, multiply 9 and -8 together (factors a*c, which equals to the sum that is b)
the result is -72
now think:
which two numbers add up to -6, but when multiplied, equal -72?
Those two numbers are -12 and 6
we can expand the polynomial:
9x²-12x+6x-8
factor by grouping:
3x(3x-4)+2(3x-4)
(3x-4)(3x+2)
so, the dimensions of the blanket are (3x-4) and (3x+2)
Hope this helps :)

The coefficient of a
To get the coefficient, we simply remove a. The remaining terms is the required coefficient
Solving (a):
[tex]Expression = 5ax[/tex]
Remove a
5x:
Hence, the coefficient is 5x
Solving (b):
[tex]Expression = -4ab[/tex]
Remove a
-4b
Hence, the coefficient is -4b
Solving (c):
[tex]Expression = 38abc[/tex]
Remove a
38bc
Hence, the coefficient is 38bc
Solving (d):
[tex]Expression=-24ab^2c[/tex]
Remove a
[tex]-24b^2c[/tex]
Hence, the coefficient is [tex]-24b^2c[/tex]

Answer:
24x² - 46x + 7
Step-by-step explanation:
Area of the shaded region = area of the larger square - area of the smaller square
✔️Area of the larger square = s²
= (5x - 4)²
= (5x - 4)(5x - 4)
= 5x(5x - 4) -4(5x - 4)
= 25x² - 20x - 20x + 16
= 25x² - 40x + 16
✔️Area of smaller square = s²
= (x + 3)² = (x + 3)(x + 3)
= x(x + 3) +3(x + 3)
= x² + 3x + 3x + 9
= x² + 6x + 9
✔️Area of the shaded region = (25x² - 40x + 16) - (x² + 6x + 9)
= 25x² - 40x + 16 - x² - 6x - 9 (distributive property)
Ad like terms
= 24x² - 46x + 7
If fg(x) = 2x + 1, and f(x) = x + 2, find g(5) and g-'f'(1).
Answer:
g(5) - f(1) = 8
g(5) = 11
Step-by-step explanation:
Given:
g(x) = 2x + 1
f(x) = x + 2
Find:
g(5)
g(5) - f(1)
Computation:
g(x) = 2x + 1
g(5) = 2(5) + 1
g(5) = 11
f(x) = x + 2
f(1) = 1 + 2
f(1) = 3
g(5) - f(1) =11 - 3
g(5) - f(1) = 8

what is eight times a number equals 4 times the 9?
Answer:
x=4.5
Step-by-step explanation:
8*x = 4*9
8x = 36
x = 4.5
Answer:
9/2
Step-by-step explanation:
Let the unknown number = n
Therefore, we can decode your question in the following manner:
8 x n = 4 x 9
Recognize that 4 x 9 = 36
So, 8 x n = 36
Lets divide 8 in both sides
n = 36/8 = 9/2
Therefore, n = 9/2

how do you write the equation of a line (in slope intercept form) with three given points?
With even just two points, you can find the equation of a line in slope-intercept form.
Slope-intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept
1) Solve for the slope ([tex]m[/tex])
The equation to solve for the slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] when the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. Plug the coordinates of these points into the equation and solve for [tex]m[/tex].
Then, plug [tex]m[/tex] into [tex]y=mx+b[/tex].
1) Solve for the y-intercept ([tex]b[/tex])
Then, take any of the given points and plug it into [tex]y=mx+b[/tex] along with the slope. Isolate [tex]b[/tex] to get the y-intercept. Then, plug both m and b back into [tex]y=mx+b[/tex] to get your final equation.

Find the Area of the Shaded Region. (15 pts)
2 m
7 m
12 m
10 m
Answer:
120 - 14 = 106
Step-by-step explanation:
7 x 2 = 14
10 x 12 = 120 therefore you,
120 - 14 = 106
The area of the shaded region is 106 m².
We have,
The area of the rectangle:
= length x width
From the figure,
Bigger rectangle dimensions:
Length = 12 m
Width = 10 m
Smaller rectangle dimensions:
Length = 7 m
Width = 2 m
Now,
The shaded region.
= Area of the bigger rectangle - Area of the smaller rectangle
= 12 x 10 - 7 x 2
= 120 - 14
= 106
Thus,
The area of the shaded region is 106 m².
