Answer:
The ratio of the volumes of the similar solids is 1331:343.
Step-by-step explanation:
Ratios
Given the ratio of two lengths is a:b. Given a two-dimensional shape is similar to another shape, the ratio of their areas is [tex](a/b)^2[/tex], and the ratio of their volumes is [tex](a/b)^3[/tex].
We know the ratio of the areas of the bases of two similar rectangular prisms is 121:49. Thus, the ratio of its dimensions is:
[tex](a/b)^2=(121/49)[/tex]
Taking the square root:
[tex]a/b = \sqrt{121/49}=11/7[/tex]
Thus, the ratio of the volumes is:
[tex](a/b)^3=(11/7)^3=1331/343[/tex]
The ratio of the volumes of the similar solids is 1331:343.
Solve [0, 2pi)
3 Cos(2x) = 5 Sin(x) - 1
Given :
Solve [0, 2π)
3cos(2x) = 5sin(x) - 1
To Find :
The value of x in range [0,2π).
Solution :
We know, cos(2x) = 1 - sin²x .
3( 1 - 2sin²x ) = 5sinx - 1
3 - 6sin²x = 5sinx - 1
6sin²x + 5sinx - 4 = 0
6sin²x + 8sinx - 3sinx - 4 = 0
2sinx( 3sinx + 4 ) - 1( 3sinx + 4) = 0
sin x = 1/2 and sin x = -4/3 .
Since, sin x ≤ 1.
So, sin x = 1/2 .
x = π/6 .
Therefore, value of x is π/6.
Hence, this is the required solution.
State the Angle Relationship & Find the measure of the indicated angle that makes lines u and v parallel.
Answer:
the indicated angle should be 121°
Step-by-step explanation:
If 2 lines are parallel to each other & a transversal intersects both of them , the corresponding angles on a same side are equal.
If the indicated angle will be equal to the given angle , they will be known as corresponding angles only when v || u.
So the indicated angle is 121°

A company sells shares in their stock for a certain price. On one sunday the price of the company's stock was $37.84 per share. This price of the stocks per share changes each day. By how much dos the price of the stock per share change from Sunday until the end of Friday? What is the price of the company's stock per share at the end of the day on Thursday?
Hi, you've asked an incomplete question. However, I assumed that the price of the stock at the end of Thursday is $43, Friday is $46.
Answer:
about +21.56% (or $8.16) by Friday
$43
Step-by-step explanation:
What we simply need to do is to note the percentage difference in price between Sunday and Friday. By subtracting the difference price we get,
$46- $37.84 = $8.16 To percentage
[tex]\frac{8.16}{37.84} *100=[/tex] 21.56%.
It is obvious from the data presented that the price of the company's stock per share at the end of the day on Thursday is $43.

Answer:
100/2=50
lower bound of 6400kg = 6350kg
10/2=5
upper bound of 90kg = 95kg

Andre rode his bike at a constant speed. He rode 1 mile in 5 minutes.
Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
A - T = 5d
B - T = 1/5 d
C - T = d+4
D - T = d-4
Answer:
B
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that Andre rode his bike at a constant speed.
Number of miles driven = 1 mile
Time taken to drive 1 mile = 5 minutes.
Then speed can be calculated using formula:
Speed = Distance / Time
Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.
Speed = Distance / Time
or
Time = Distance / Speed
Plug the given values
t = 5d
Hence find answer will be equation t=5d.

7. What are the x-intercepts of the graph of y = (3x +8)(5x - 3)(x - 1)?
Answer:
y = 15x^3 + 16x^2 - 55x + 24
Step-by-step explanation:
y = (3x +8)(5x - 3)(x - 1)
y = (15x^2 - 9x + 40x -24) * (x - 1)
y = (15x^2 + 31x - 24) * (x-1)
y = 15x^3 - 15x^2 + 31x^2 - 31x - 24x + 24
The x-intercepts of a graph are the points where the graph crosses the x-axis.
The x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]
The function is given as:
[tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]
First, we plot the graph of [tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]
See attachment for the graph
Next, write out the x-values when the graph crosses the x-axis.
From the graph, we have:
[tex]\mathbf{x = -\frac 83}[/tex]
[tex]\mathbf{x = \frac 35}[/tex]
[tex]\mathbf{x = 1}[/tex]
Hence, the x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]
