−42v+33<8v+91 solve for v
Answers
33 - 91 < 8v + 42v
-58 < 50v
-58/50 < v
-29/25 < v
or
v > -29/25
The value of v is v > -1.16.
What are Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given linear inequality is
−42v + 33 < 8v + 91
We have to take like terms on one side.
-42v and 8v are like terms and 33 and 91 are like terms.
Subtracting 8v from both sides,
−42v + 33 - 8v < 8v + 91 - 8v
-50v + 33 < 91
Subtracting 33 from both sides,
-50v + 33 - 33 < 91 - 33
-50v < 58
Dividing both sides by -50, the inequality sign changes.
v > -58 / 50
v > -1.16
Hence the solution for the inequality is v > -1.16.

an ice cream factory makes 260 quarts of ice cream in 10 hours. How many quarts could be made in 36 hours? What was that rate per day?
Answers
260 * 20 hours = 5,200 quarts ---> 260 quarts / 10 hours = 26 quarts per hour ---> 26 quarts * 4= 104 quarts ---> 5,200 + 104 = 5,304 quarts per day
Final answer:
The ice cream factory can make 936 quarts in 36 hours and the rate per day is 624 quarts.
Explanation:
To find out how many quarts of ice cream can be made in 36 hours, we can set up a proportion based on the rate of production. The rate of production is 260 quarts of ice cream in 10 hours. We can set up the proportion:
260 quarts / 10 hours = x quarts / 36 hours
Cross-multiplying, we get:
10x = 260 * 36
Simplifying, we find:
x = (260 * 36) / 10 = 936
Therefore, 936 quarts of ice cream can be made in 36 hours.
To find the rate per day, we need to calculate how many quarts can be made in 24 hours. We can set up the proportion:
260 quarts / 10 hours = y quarts / 24 hours
Cross-multiplying, we get:
10y = 260 * 24
Simplifying, we find:
y = (260 * 24) / 10 = 624
Therefore, the rate per day is 624 quarts of ice cream.

What is the slope of the line shown?
Answers
Answer:
Option (b) is correct.
The slope of line shown in given graph is [tex]\frac{9}{7}[/tex]
Step-by-step explanation:
Given: A graph with an equation of line having two points (1,6) and (-6, -3)
We have to find the slope of the given line in graph and choose the correct from the given options.
Consider the two points (1,6) and (-6, -3).
Slope between two points can be calculated using the formula as,
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here, [tex]\left(x_1,\:y_1\right)=\left(1,\:6\right),\:\left(x_2,\:y_2\right)=\left(-6,\:-3\right)[/tex]
Thus, Slope is
[tex]m=\frac{-3-6}{-6-1}=\frac{9}{7}[/tex]
Thus, The slope of line shown in given graph is [tex]\frac{9}{7}[/tex]

Where the "-pi/2" part is its own fraction (x is not part of it; i.e., x is not in the numerator of the fraction).
-------------------------------------
To find this answer, we need to ask ourselves: "1/3 times what quantity will give us (1/3)x?". The answer to this sub-question is simply x. In other words, 1/3 times x is (1/3)x. That takes care of the first part.
For the second part, we have 1/3 times something equal to -pi/6. That "something" must be -pi/2. Note how
(1/3)*(-pi/2) = (1*(-pi))/(3*2) = -pi/6
So you have to think backwards in a sense. Or you can treat it like this
(1/3)*y = -pi/6
Multiplying both sides by 3 leads to
y = -pi/2
[tex] \frac{1}{3} [/tex] x - [tex] \frac{ \pi}{6} [/tex] = [tex] \frac{1}{3} [/tex] [([tex] \frac{1}{3} [/tex] ÷ [tex] \frac{1}{3} [/tex] x) - ([tex] \frac{ \pi}{6} [/tex] ÷ [tex] \frac{1}{3} [/tex] )]

What is the radius of a circle with circumference 27 in.?
Answers
The radius of a circle with a circumference of 27 inches can be calculated using the formula for the circumference of a circle which is 2πr. Calculating this, the radius is approximately 4.3 inches.
Explanation:The subject of this question is Mathematics, more specifically, Geometry which deals with shapes, sizes and properties of figures. In this case, we are being asked to find the radius of a circle given its circumference. The circumference of a circle is calculated as 2πr, where r represents the radius and π is approximately equal to 3.14.
To find the radius (r), you would divide the circumference by 2π. Given that the circumference of the circle is 27 inches, we divide 27 by 2π (approximately 6.28). This can be further simplified to approximately 4.3 inches.

What is the measure of an exterior angle of a regular 11-sided polygon? enter your answer as a decimal in the box. round to the nearest tenth of a degree?
Answers
In general sum of interior angle of any polygon = [tex](n-2)*180[/tex]
Where n is no. of sides in polygon.
We can find value of each interior angle in any polygon as
[tex] \frac{(n-2)*180}{n} [/tex]
For polygon of 11 sides
Value of each interior angle is
[tex] \frac{(11-2)*180}{11} [/tex]
[tex] \frac{9*180}{11} = \frac{1620}{11} = 147.272727..... [/tex]
So value of each interior angle in 11 sided polygon is 147.272727..... which we can round it as 147.28 degree.
Value of exterior angle in polygon = 180 - interior angle
= 180 - 147.28 = 32.72 degree.
So the value of exterior angle in 11 sided polygon is = 32.72 degree.

Answer:

Step-by-step explanation:
Line SV is an angle bisector of angle RST
<RSV = <VST
Both angles are equal
m<RSV = (3x+5)
<RSV = <VST, so m<VST = (3x+5), m<RST= 8x-14
m<RST= m<RSV +m<VST
[tex]8x-14= 3x+5+3x+5[/tex]
Combine like terms and solve for x
[tex]8x-14= 6x+10[/tex]
Subtract 6x from both sides
[tex]2x-14=10[/tex]
Add 14 on both sides
[tex]2x=24[/tex]
Divide both sides by 2
