you should try to keep it under 5 minutes.
since there will be easier ones and harder ones, its ok to take up to 10 minutes on a test as long a you try to get the easy ones done first. if you can skip questions then go back to them later, do the hardest ones first thengo back and do the easier ones afterwards.
Try to take your time when you need to. if you get stuck, think about what it says. Try to think of it another way. You also want to get as much done as you can, this is because if you miss 5-10 questions, the grade could be seriously decreased, as you might have gotten a few other questions wrong.
Make sure to do a "QC" as I call it; or a "Quick Check." If it looks good and it's reasonable then you are fine to move on. it it doesnt look right, retrace your steps. Then rewrite it if you got something else on your next try for the QC.
I hope you do good!
May luck be with you!

Answer:
1,044cm
Step-by-step explanation:
46-21=25cm (the length of the top line)
30-14=16cm (the length of the other line on the left of the 21)
Split it into three rectangles, 25×16, 21×14 and 25×14
25×16 = 400cm
21×14 = 294cm
25×14 = 350cm
Add to together: 400+350+294= 1044cm

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...
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.

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

find the slope of the line that passes through the points (-6, - 18) and (-7, -17)
Answer:
-1
Step-by-step explanation:
The slope is the change in the Y value divided by the change in the X value. Therefore, the slope of this line is:
(-17-[-18])/(-7-[-6) = (-17+18)/(-7+6) = (1)/(-1) = -1

What is the slope of the compass needle (the bottom red line)?
Answer:
176/317
Step-by-step explanation:
The formula for slope is [tex]\frac{y2 - y1}{x2 - x1}[/tex], which means you have to subtract the second point's y coordinate (286) minus the first point's y coordinate (110).
Now you have [tex]\frac{286-110}{x2 - x1}[/tex] or [tex]\frac{176}{x2 - x1}[/tex].
Now you have to do the same for x.
446 - 129 = 317, which gives you the final answer of
[tex]\frac{176}{317}[/tex], or about 0.555.

Given that z = 10 cis 30° and w = 5 cis 10°, find z/w. Leave your answer in polar form
Giving almost 100 pts!!
Answer:
2cis(20°)
Step-by-step explanation:
we are given that
[tex] \displaystyle \rm z = 10cis ({30}^{ \circ} )[/tex]
[tex] \displaystyle \rm w = 5cis ({10}^{ \circ} )[/tex]
We want to find z/w . To do so, divide 10cis(30°) by w = 5cis(10°) which yields:
[tex] \displaystyle \rm \frac{ z}{w} = \frac{10cis ({30}^{ \circ} )}{5cis( {10}^{ \circ} )}[/tex]
recall that,
[tex] \displaystyle \rm \frac{ r_{1} cis ({ { \theta}_{1}} )}{ r_{2}cis( { \theta}_{2})} = \frac{ r_{1} }{ r_{2} } cis({ \theta}_{1} - { \theta}_{2})[/tex]
consider,
[tex]{ r}_{1} \implies 10[/tex][tex]{ r}_{2} \implies 5[/tex][tex]{ \theta}_{1} \implies {30}^{ \circ} [/tex][tex]{ \theta}_{2} \implies {10}^{ \circ} [/tex]Therefore, utilizing the formula yields:
[tex] \displaystyle \rm \frac{ z}{w} = \frac{10cis ({30}^{ \circ} )}{5cis( {10}^{ \circ} )} \\ \implies \rm\frac{ z}{w} = \dfrac{10}{5} cis( {30}^{ \circ} - {10}^{ \circ} ) \\ \implies \rm \dfrac{z}{w} = \boxed{ \rm2cis( {20}^{ \circ} )}[/tex]
and we're done!

Answer:
Height - 12.692 in

Step-by-step explanation:
Replace are and base to get:
82.5 = 1/2 x 15 x height
Multiply both sides by 2:
165 = 15 x height
Divide both sides by 15:
Height = 165 / 15
Height = 11 inches.

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
Given,
(3 + 2i)(5 – 2i)
Here,
Complex numbers standard form : x ± iy
Here,
x = real part
y = complex part.
i = iota = [tex]\sqrt{-1}[/tex]
So,
Multiplication : (3 + 2i)(5 – 2i)
⇒15 -6i + 10i -4i²
Here,
i = √-1
i² = -1
So,
15 -6i + 10i -4i²
15 -6i + 10i - 4(-1)
⇒19 + 4i

Answer:
a) -3p +4q
b) -6x +3y
Step-by-step explanation:
Use the distributive property to eliminate parentheses. Use the properties of arithmetic to combine the numbers.
__
a)The order of operations tells you to start with the inner parentheses and work outward.
[tex]-\dfrac{1}{3}(6(p+q)-3(p-2(p-3q)))=-\dfrac{1}{3}(6(p+q)-3(p+(-2)(p) +(-2)(-3q)))\\\\=-\dfrac{1}{3}(6(p+q)-3(p-2p+6q))=-\dfrac{1}{3}(6(p+q)-3(-p+6q))\\\\=-\dfrac{1}{3}((6)(p)+(6)(q)+(-3)(-p)+(-3)(6q))=-\dfrac{1}{3}(6p+6q+3p-18q)\\\\=-\dfrac{1}{3}(9p -12q)=(-\dfrac{9p}{3})+(-\dfrac{-12q}{3})=\boxed{-3p+4q}[/tex]

b)Same deal for the second expression: use the distributive property and combine like terms.
[tex]y-\dfrac{2}{3}(9x-3y)=y+(-\dfrac{2\cdot9x}{3})+(-\dfrac{2(-3y)}{3})\\\\=y-6x+2y=\boxed{-6x+3y}[/tex]
