Answer:
[C] 4x - 19 < 318
Step-by-step explanation:
For [C] I think you meant: [C] 4x - 19 < 318
Since, x = -8
then we can plug it in to each answer choice to find the answer:
[A] -3x - 2 = 24
⇒ -3(-8) - 2 = 24
-3(-8) = 24
24 -2 = 22 not 24
False.
[B] 12 + 2x > 9
⇒ 12 + 2(-8) > 9
12 -16 > 9
-4 > 9
False.
[C] 4x -19 < 318
⇒ 4(-8) -19= 318
-51 < 318
True.
[D] 17 + x>10
⇒ 17 + (-8) >10
-25 > 10
False.
Hence, the answer is [C] 4x - 19 < 318

An electric guitar costs $830, with a $225 full-replacement warranty. if the manufacturer sells 532,475 warranties and has to honor 12% of them, how much profit did the manufacturer gain from the warranties? a. $105,430,050 b. $66,772,365 c. $53,034,510 d. $508,726,615
The profit which the manufacturer gained from the warranties is a. $105,430,050
Calculations and Parameters:Given that count 12% of 532,475:
532,475 - 100%
x - 12%
x= 63, 897.
This means that 63, 897 guitars were sold with a full-replacement warranty and 532,475-63,897=468,578 electric guitars were sold without a full-replacement warranty.
Hence, to find the gain of the manufacturer, $225·468,578
=$105,430,050 from the warranties.
Option A is correct: $105,430,050

h = 15 ft
Step-by-step explanation:
the line from the vertex to the base is a perpendicular bisector.
then the radius r = 16 ÷ 2 = 8
using Pythagoras' identity in the right triangle formed
with hypotenuse = 17 and legs h and 8 , then
h² + 8² = 17²
h² + 64 = 289 ( subtract 64 from both sides )
h² = 225 ( take square root of both sides )

solve the equation using square root method, show work
Answer:
Step-by-step explanation:
2(x+7)^2 =98
(x+7)^2 = 49 (divide both sides by 2)
(x +7) = [tex]\sqrt{49}[/tex] (square root both sides)
x + 7 = 7 ( we are not sure if this is -7 or +7, because either would work )
so we have two solutions now
x +7 = -7 or x +7 = 7
x = -7 -7 or x =7 -7 (subtract 7 from both sides)
x = - 14 or x = 0
A town has a population of 72,700 and grows at a rate of 3.5% every year. Which equation represents the town’s population after 4 years?
Answer:
for 4 years: [tex]72,700 + 1.035^4(72,700)[/tex]
For n years: [tex]72,700 + 1.035^n(72,700)[/tex]
Step-by-step explanation:
Since each year the growth rate is 3.5 of the last year, n will represent the number of years.
[tex]72,700 + 1.035^n(72,700)[/tex]
Therefore since n is 4, the equation will be:
[tex]72,700 + 1.035^4(72,700) =72,700 + 1.15(72,700)[/tex]
Therefore this equation represents the town after four years.

Answer:
A. 9y + 3 = 0
Step-by-step explanation:
To know if a function is linear without graphing it, check if the function is a polynomial of the first degree, because linear functions are polynomials of the first degree. This means that the power of the x-value should be equal to 1.
The only function without this trait is 9y + 3 = 0, so that is our nonlinear function.

Answer:
Below in bold.
Step-by-step explanation:
Mean = (98+92+90+78+83+88+95)/7
= 89.1 to nearest tenth.
Deviations:
98 - 89.1 = 8.9
92 - 89.1 = 2.9
90 - 89.1 = 0.9
78 - 89.1 = -11.1 = 11.1 (absolute value)
83 - 89.1 = 6.1
88-89.1 = 1.1
95 - 89.1 = 5.9
So the MAD
= (8.9+2.9+0.9+11.1+6.1+1.1+5.9)/7
= 36.9/7
= 5.27
= 5.3 to nearest tenth.

The circumference of a globe is 16pi inches. what is the volume of the globe? show your work. use 3.14 for pi
Answer:
v=2144.66
Step-by-step explanation:
formula: 4/2 (pi) (r)³
................
Answer:
V = 2143.573333333333.... in³
Step-by-step explanation:
Formula for volume -> V = 4/3 πr³
We know the circumverence now we need to et the radius.
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
There you go, you found the circle's radius.
16pi/pi = 16/2 = 8
V=4/3πr³
V=4/3π8³ = 2143.5733333333333333333333333333333333333333333333333333333333333...
Instructions: Find the measure of the indicated angle.
Answer:
x = 66
Step-by-step explanation:
the triangle has 2 congruent sides and is therefore isosceles with the 2 base angles being congruent, then
x = 66
The measure of the indicated angle is 66 degree.
What is Isosceles Triangle ?An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:
It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.We have a Triangle.
Then, using Isosceles Triangle Theorem
Angles opposite an isosceles triangle's equal sides are also equal.
According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.
So, x= 66 degree.

A Ferris wheel has a radius of 80 feet. Two particular cars are located such that the central angle between them is 165º. To the nearest tenth, what is the length of the intercepted arc between those two cars on the Ferris wheel?
Answer: 230.4 feet
Step-by-step explanation:
arc length = circumfrance x fraction of a circle
= [tex]2\pi r[/tex] x [tex]\frac{165}{360}[/tex]
= [tex]\frac{2*\pi *80*165 }{360}[/tex]
= 230.4 feet to nearest tenth
The length of the intercepted arc between those two cars on the Ferris wheel is 230.4 feet. This is obtained by using the arc length formula in degrees.
Arc length:The distance across the curved length is said to be arc length.
The arc length is calculated by using the formula:
arc length = circumference × fraction of circle
⇒ arc length = 2πr × θ/360° when θ is given in degrees
where r is the radius.
Given data:Given that,
A Ferris wheel has a radius of r=80 feet
Two particular cars are located such that the central angle between them is 165° i.e., θ = 165°
Calculating the length of the arc:arc length = 2πr × θ/360°
⇒ 2π×80×[tex]\frac{165}{360}[/tex]
⇒ 230.38 feet
Rounding off to the nearest tenth, we get arc length = 230.4 feet.

Multiply the complex numbers: (3 + 2i)(5 – 2i)
Answer:
19+4i
Step-by-step explanation:
Multiply using the FOIL method, then combine the real and imaginary parts of the expression.
FOIL
A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial, Outer means multiply the outermost terms in the product, Inner means multiply the innermost terms, and Last means multiply the terms which occur last in each binomial.
Result of multiplication of complex numbers will be 19 + 4i
