Step-by-step explanation:
they make one stop every 150 miles
900/150 = 6 stops
The family will make 6 stops for a trip of 900 miles.
So, the answer is B. 6.
Given is table showing number of stops made and the number of miles the family traveled.
The number of times the family stops to rest during a trip is dependent upon the number of miles the family travels.
We need to determine the number of stops the family will make for a trip of 900 miles.
To predict the number of stops the family will make for a trip of 900 miles, we can observe the pattern in the given data.
From the table, we can see that the number of stops is increasing by 1 for every 150 miles traveled.
So, to find the number of stops for 900 miles, we can divide 900 by 150 and round up to the nearest whole number since the number of stops cannot be a fraction.
900 miles / 150 miles = 6
Therefore, the family will make 6 stops for a trip of 900 miles.
So, the answer is B. 6.

which of the following equations is equivalent to log(y) = 4.876
Answer:
[tex]10^{4.876}=y[/tex]
Step-by-step explanation:
Logarithms are just another way of arranging an exponential equation! You know how you can rearrange the equation 2 + 3 = 5 as 5 - 3 = 2, or the equation 2 x 3 = 6 as 6 ÷ 3 = 2? With logarithms, you can do the same thing with an equation like 2³ = 8. As a logarithm, we would write this equation as log₂(8) = 3. Here, we call 2 the base, 8 the argument, and 3 the exponent.
Logarithms like the one in the problem with a base of 10 are just written as log, without the base written out. In the equation log(y) = 4.876, our base is 10, our argument is y, and our exponent is 4.876, so as an exponential equation, we would write it as

Answer:
2 docenas cuestan $61.200.
Step-by-step explanation:
Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:
12*2=24
Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:
$2.550*24=$61.200
De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.
Does this graph show a function? Explain how you know.
Answer:
C
Step-by-step explanation:
It passes the vertical line test
the vertical line test is taking a vertical line and putting it anywhere on the graph, and if it passes 2 points, it fails, and since if you put the line anywhere, it only passes one point of the parabala, so it passes the line test
Answer: C
Step-by-step explanation: The easiest way to determine if a
relation is a function is to use the vertical line test.
The vertical line test tells us that if we can draw a vertical line
that intersects more than one point on the graph of a relation,
then the relation is not a function.
However, in this case, notice that there is no way to draw a
vertical line that intersects more than one point on the graph.
Therefore, this relation must be a function.

60 cm
Calculate the volume of water needed to fill the tank
Answer:
a) The volume of the sphere is approximately 14,137.16694 which is 14,140 cm³ correct to 4 significant figures
b) The volume of water required to fill the tank is approximately 103,670 cm³
Step-by-step explanation:
a) In the question, the radius of the sphere, r = 15 cm
The formula for the volume, 'V', of a sphere is given as follows;
[tex]V = \dfrac{4}{3} \times \pi \times r^3[/tex]
Where;
r = The radius of the the sphere
V = The volume of the sphere
Plugging in the value for the radius, 'r', of the sphere, in the equation for, 'V', we get;
[tex]V = \dfrac{4}{3} \times \pi \times 15^3 \approx = 14,137.16694[/tex]
Therefore;
The volume of the sphere to 4 significant figures is V ≈ 14,140 cm³
b) The parameters of the cylindrical tank are;
The height of the cylindrical tank, h = 60 cm
The radius of the cylindrical tank, r = 25 cm
The volume of a cylinder, V = π·r²·h
∴ The volume of the cylindrical tank without water, '[tex]V_t[/tex]', is given as follows;
[tex]V_t[/tex] = π × (25 cm)² × 60 cm ≈ 117809.72451 cm³
The volume of water, [tex]V_{water}[/tex], required to fill the tank with the sphere of volume 'V' placed inside is given as follows
[tex]V_t[/tex] = V + [tex]V_{water}[/tex]
∴ [tex]V_{water}[/tex] = [tex]V_t[/tex] - V
From which we get;
[tex]V_{water}[/tex] ≈ 117809.72451 cm³ - 14,140 cm³ = 103,669.72451 cm³ ≈ 103,670 cm³
The volume of water required to fill the tank, [tex]V_{water}[/tex] ≈ 103,670 cm³.

If the sum of the measures of the interior angles of a polygon is 1920°, how many sides does it have? math
Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-
[tex](n-2)\times180^{\circ}[/tex]
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]
[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

jelly-filled donut contains an amount of energy
equal to about 0.5 kilowatt-hours. If that energy
could be converted into electrical energy, how
long would it keep a 15-watt night light lit?
A 15 watt night light would keep up to lit for 33.33 hours.
What is Energy?Energy in simple definition can be defined as the ability to do work. Energy can be converted into various forms and can be used to do the work.
The formula for calculating energy is,
Energy = Power × Time
Given that energy of one jelly filled donut contains an amount of energy equal to 0.5 kilowatt hours.
1 kilowatt = 1000 watts
0.5 kilowatt hour = 500 watts hour
Now this energy is converted into electrical energy and used it to lit 15 watt night light.
Power of the light = 15 watts
Energy = 500 watts hour
Time = Energy / Power
= 500 / 15
= 33.33
Hence 15 watt light will lit for 33.33 hours.
