Answer:
94 minutes
Step-by-step explanation:
To get to 9:00, we add 6 minutes. From 9 to 10, there's 60 minutes. From 10 to 10:28, there's 28 minutes.
If we add them all together we get 94 minutes or 1 hour and 34 minutes.

Line segment xy is dilated to create line segment x'y' using point t as the center of dilation. point t is the center of dilation. line segment x y is dilated to create shorter line segment x prime y prime. the length of t x prime is 6 and the length of t y prime is 9. the length of x x prime is 2. what is yt? 3 units 6 units 12 units 15 units
The length of segment YT will be equal to 12 units as the line segment XY is dilated to create line segment X'Y' using point t as the center of dilation.
What is dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem
Triangles XYT and X'Y'T are similar to the AA Similarity Theorem
[tex]\dfrac{XT}{YT}=\dfrac{X'T}{Y'T}[/tex]
substitute the given values
[tex]\dfrac{8}{YT}=\dfrac{6}{9}[/tex]
[tex]YT=\dfrac{9\times 8}{6}[/tex]
[tex]YT=12\ units[/tex]
Hence the length of segment YT will be equal to 12 units as the line segment XY is dilated to create line segment X'Y' using point t as the center of dilation.

-12x - 7=53 ill give brainlies
Answer:
x=-5
Step-by-step explanation:
-12x-7=53
+7=+7
-12x=60
divide both sides by negative 12
60/-12= -5
so x =-5
The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The equation with a single variable 'x' is given below.
- 12x - 7 = 53
Simplify the equation, then we have
- 12x - 7 = 53
- 12x = 60
x = 60 / (-12)
x = - 5
The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-2}{2}\implies -1[/tex]
Step-by-step explanation:
To find the slope, take 2 points from the graph. I'm going to pick (0,2) and (1,1). Whenever we find the slope this way, we need to keep this formula in mind:
[tex] \frac{y2 - y1}{x2 - x1} = slope[/tex]
So, in this case, we need to do this:
[tex] \frac{1 - 2}{1 - 0} = \frac{ - 1}{1} [/tex]
So the answer is -1.

The measure of center that would best describe a typical value of the data set is a mean since the values are close.
What is a measure of center?It should be noted that the measure of center include the mean, median, mode, and the mid-range.
In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.
Therefore, the mean of the numbers will be:

A cup has the shape of a right circular cone. The height of the cup is 16 cm, and the radius of the
cm opening is 4 cm. Water is being poured into the cup at a constant rate of 3 cm. At what rate, in
cm per second, is the water level rising when the depth of the water in the cup is 6 cm? (The volume of a cone of height h and radius r is given by V=1/3pir^2h.
1. 1/64pi
2. 3/pi
3. 4/3pi
4. 9/4pi
Answer:
3. [tex]\dfrac{4}{3 \pi}[/tex]
Step-by-step explanation:
Volume of a cone:
[tex]V=\dfrac13\pi r^2h[/tex]
(where r is the radius and h is the height)
Given:
h = 16 cmr = 4 cm[tex]\implies r=\dfrac14h[/tex]
Therefore, substitute [tex]r=\frac14h[/tex] into the volume formula to find the volume of the cone in terms of h:
[tex]\implies V=\dfrac13\pi \left(\dfrac14h\right)^2h[/tex]
[tex]\implies V=\dfrac{1}{48}\pi h^3[/tex]
Differentiate with respect to h:
[tex]\implies \dfrac{dV}{dh}=3 \cdot \dfrac{1}{48} \pi h^2=\dfrac{\pi h^2}{16}[/tex]
Volume is increasing at a constant rate of 3cm/s:
[tex]\implies \dfrac{dV}{dt}=3[/tex]
Use the chain rule to find [tex]\dfrac{dh}{dt}[/tex]
[tex]\implies \dfrac{dh}{dt}=\dfrac{dV}{dt}\times\dfrac{dh}{dV}[/tex]
[tex]\implies \dfrac{dh}{dt}=3\times\dfrac{16}{\pi h^2}[/tex]
[tex]\implies \dfrac{dh}{dt}=\dfrac{48}{\pi h^2}[/tex]
When h = 6:
[tex]\implies \dfrac{dh}{dt}=\dfrac{48}{\pi \cdot 6^2}=\dfrac{4}{3 \pi}[/tex]
