Mr Hong is a rare coin collector. He recently bought a coin valued at $5400. It has been determined that the coin will increase in value by $30 each month. Mr Hong plans to sell the coin within 5 years. a. name the quantities that stay the same in this problem situation & the quantities that remain constant .
Answers
Months would be your independent variable
Total cost would be dependent
Therefore, your total cost would “depend” on the number of months “independent” times your constant of 30

For 6 is the same so divide 144 by 2 which is 72
7 and 8 are different questions from 5 and 6 and use their own method for a solution.
7 requires understanding that opposite angles when lines are crossed equal each other. For 7 the two angles will be 85 and opposite it is 85 so add them together and subtract from 360 which is the total angle of a circle. Which is 190 and divide that by 2 which is 95. So angle D for 7 is 95 degrees. 8 is just an opposite angle so it’s 120 degrees

Answers
Answer:
Isosceles triangle.
Step-by-step explanation:
The first side of the given triangle = 6 units
The second side of the given triangle = 6 units
The third side of the given triangle = 9 units
In an isosceles triangle, two sides of a triangle are equal and if sides are equal they have the same angle at the base.

Answer:
A. 45.7
Step-by-step explanation:
Side a = 8
Side b = 7.8
Side c = 11.17318
Angle ∠A = 45.725° = 45°43'31" = 0.79806 rad
Angle ∠B = 44.275° = 44°16'29" = 0.77274 rad
Angle ∠C = 90° = 1.5708 rad = π/2
=======================================================
Explanation:
Apply the tangent ratio and inverse tangent function (aka arctangent) to get the following
tan(angle) = opposite/adjacent
tan(x) = 8/7.8
x = arctan(8/7.8)
x = 45.7252242990592
x = 45.7

A grain silo is built from two right circular cones and a right circular cylinder with internal measurements represented by the figure above. Of the following, which is closest to the volume of the grain silo, in cubic feet?
A) 261.8
B) 785.4
C) 916.3
D) 1047.2
Answers
Answer:
Step-by-step explanation: The volume of the grain silo can be found by adding the volumes of all the solids of which it is composed (a cylinder and two cones). The silo is made up of a cylinder (with height 10 feet and base radius 5 feet) and two cones (each with height 5 ft and base radius 5 ft). The formulas given at the beginning of the SAT Math section:
Volume of a Cone:
[tex]V=\frac{1}{3} \pi r^2h[/tex]
Volume of a Cylinder:
[tex]V=\pi r^2h[/tex]
can be used to determine the total volume of the silo. Since the two cones have identical dimensions, the total volume, in cubic feet, of the silo is given by
[tex]V_{silo} =\pi (5^2)(10)+(2)(\frac{1}{3})\pi (5^2)(5)=(\frac{4}{3})(250)\pi[/tex]
which is approximately equal to 1,047.2 cubic feet.
The final answer is D.

A set of data has the trend line modeled by the equation Y =1.5x + 11. What value of X corresponds to y =56?
Answers
Answer:
x = 30
Step-by-step explanation:
Plug in 56 in place of y, then solve for x.
56 = 1.5x + 11
Subtract 11.
45 = 1.5x
Divide both sides by 1.5.
45/1.5 = x
30 = x

What is trigonometry?
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
Two geometric objects are perpendicular in simple geometry if they intersect at a right angle. If two lines cross at a right angle, they are said to be perpendicular to one another.
The line CE is making an angle of 90 degrees with the line AB, then the line CE will be perpendicular to the line AB.
Therefore, the perpendicular line AB is segment CE only. The correct option is A.

A wildlife refuge in South America has howler monkeys and spider monkeys. A biologist working there randomly selected eight adults of each type of monkey, weighed them, and recorded their weights in pounds.

spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}
(a) Calculate the mean and MAD for each type of monkey.
(b) Calculate the means-to-MAD ratio for the two types of monkeys.
(c) What inference can be made about the weight of both types of monkeys? Explain.
when answering please seperate the answers with either 1, 2, 3 or a, b, c! thank you
Answers
Answer:The mean for the howler monkeys is 17 and the MAD is 0.8571.
The mean for the spider monkeys is 14 and the MAD is 1.1429.
The means-to-MAD ratio is 2.6249.
Step-by-step explanation:
To find the mean of the howler monkeys, add all of the data values and divide by 7:
(15+16+17+17+17+17+18+19)/7 = 119/7 = 17
To find the MAD, subtract each data point from the mean; take the absolute deviation; then average these together:
(|15-17|+|16-17|+|17-17|+|17-17|+|17-17|+|17-17|+|18-17|+|19-17|)/7
=(2+1+0+0+0+0+1+2)/7=6/7 = 0.8571
Repeating these processes for the spider monkeys:
Mean:(12+13+13+14+14+14+16+16)/7 = 98/7 = 14
MAD:
(|12-14|+|13-14|+|13-14|+|14-14|+|14-14|+|14-14|+|16-14|+|16-14|)/7
=(2+1+1+0+0+0+2+2)/7 = 8/7 = 1.1429

Answers
Answer:
D (i hope)
Step-by-step explanation:
When you minus the highest to the lowest it is added by 10 so
160-140= 20
140-110=30
110-70= 40
70-20= 50
I had added 10 to 160 and got 170
Listen ducky:
160-140=20
140-110=30
110-70=40
70-20=50
20+30+40+50+10 (we need to add 10 on every part because of the question), so 10+10+10+20+30+40+50=170
The answer is D, my dear duck

No. of families = 75
Out of 75 no. of families had cars = 42
Out of 1, no. of families can have cars
[tex] = \frac{42}{75} [/tex]
Therefore,
Out of 200 families, no. of families had cars
[tex] = 200 \times \frac{42}{75} [/tex]
[tex] =200 \times \frac{14}{25} [/tex]
= 8 × 14
