The chart shows the results of 20 spins that Kristie made with a spinner.
Based on these results, what is the probability that Kristie's spinner will land on Mexico the next time?
Answer:
3 / 10
Step-by-step explanation:
The required outcome = mexico ; number of spins = 6 spins
Total possible outcomes = sum. Of all spins = (6 + 4 + 5 + 5) = 20
P(Mexico on next spin) = required outcome / Total possible outcomes
P(Mexico on next spin) = 6 / 20 = 3 / 10
saniyah collected a total of 9 seashells she gave 1/3 to her sis how many seashells did Saniyah have left?
Answer: The answer is 3.
Step-by-step explanation: You would multiply 9x1/3 which would give you 3. If you want to understand even better here's how to do so: Put 3(the answer that you got from multiplying 9x1/3) into the fraction 1/3 as 1. In other words, it would look something like this 3/3. Then, just multiply the two numbers 3x3 and that equals 9, the number you started with.
Hope that this helped!!:)
Considering the provided information in the given question, we have :
Total seashells Saniyah have = 9Number of seashells Saniyah gave to her sister = [tex]\sf \dfrac{1}{3} [/tex] of total.We need to find how many seashells did Saniyah have left.
⇒ Number of seashells Saniyah have left = Total seashells – Number of seashells she gave to her sister
⇒ [tex] \sf {Left \: seashells = 9 - \Bigg \lgroup \dfrac{1}{3} \times 9 \Bigg \rgroup } [/tex]
⇒ [tex] \sf {Left \: seashells = 9 - \Bigg \lgroup 1 \times 3 \Bigg \rgroup } [/tex]
⇒ Left seashells = 9 – 3
⇒ Left seashells = 6
Therefore, Saniyah have left [tex] \bf {6 \: seashells } [/tex].

without peeking into it, find the probability of getting a green or red candy.
Answer:
[tex]P(Green\ or\ Red) = 0.30[/tex]
Step-by-step explanation:
Given
[tex]White = 40[/tex]
[tex]Green = 24[/tex]
[tex]Red = 12[/tex]
[tex]Yellow = 24[/tex]
[tex]Blue = 20[/tex]
Required
[tex]P(Green\ or\ Red)[/tex]
The total numbe of candy is:
[tex]Total = 40 + 24 + 12 + 24 + 20[/tex]
[tex]Total = 120[/tex]
This probability is calculated as:
[tex]P(Green\ or\ Red) = P(Green) + P(Red)[/tex]
For each, we have:
[tex]P(Green\ or\ Red) = \frac{Green}{Total} + \frac{Red}{Total}[/tex]
Take LCM
[tex]P(Green\ or\ Red) = \frac{Green+Red}{Total}[/tex]
[tex]P(Green\ or\ Red) = \frac{24+12}{120}[/tex]
[tex]P(Green\ or\ Red) = \frac{36}{120}[/tex]
[tex]P(Green\ or\ Red) = 0.30[/tex]

the area of a circle is 0.2826 square miles. what's is the circle's radius? use 3.14 for pi
I need more help this is so bad
Answer:
perimeter of square=4×side
perimeter of square =4×13cm
perimeter of square = 52cm
area of square = side²
area of square = (13cm)²
area of square = 169cm²
Answer:
52 cm / 169 cm²
Step-by-step explanation:
To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.
13 + 13 + 13 + 13 = 52
The perimeter is 52 cm.
The area is the length times the width of the shape, so we have to multiply 13 by 13.
13 · 13 = 169
The area is 169 cm².
The answer is the third option, 52 cm / 169 cm².
Good luck :)

ABCD m angle ACD=2x+4 and m angle ACB=5x-5 . For what value of ABCD rhombus?
Please help quick ! This is a timed test
Answer:
I don't have a picture but since it is a rhombus, I'll give it my best shot.
IF those two angles are across from each other, they are equal, then:
2x+4 = 5x-5
add 5 to each side of the equation:
2x+9 = 5x
subtract 2x from each side:
3x = 9
divide both sides by 3:
x = 3
IF those two angles are adjacent, their sum is 180°, then:
2x+4 + 5x-5 = 180°
combine like terms:
7x - 1 = 180
add 1 to each side of the equation:
7x = 181
divide both sides by 7:
x = 25.86

Find the surface area of each figure. Round answers to two decimal places. Use 3.14 for pi
Answer:
the top wpuld be 73.14 and i cant see the numbers at the bottom
Step-by-step explanation:
The total surface area of the given figure which has cone and hemisphere is 944.08 square inches
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Let us find the height of the cone by using pythagoras theorem
7²+h²=15²
49+h²=225
Subtract 49 from both sides
h²=225-49
h²=176
h=13.2
Now let us find surface area of cone
A=πr(r+√(h²+r²))
A = 482.5
The surface area of hemisphere is 3πr²
A=3×3.14×(7)²
=3×3.14×49
=461.58
The total surface area = 482.5+461.58
=944.08 square inches
Hence, the total surface area of the given figure which has cone and hemisphere is 944.08 square inches

The measure of
the arc is for all and each no rush!
Answer:
Step-by-step explanation:
1)
The given angle is 57° at least I think it is . so we need to look at the triangle being formed inside the circle. the legs from the center to the edge are both the radius. so they are the same lengths. so that triangle is an isosceles. and the two angle at the circles perimeter are going to be both the same, b/c that's a rule of an isosceles triangle. so now we not both angles on the perimeter of the circle of that inner triangle are both 57° :) that's great, b/c now we can find the angle of the inner point of that triangle. it's going to be 180 = 57 + 57 + inner angle x
180 - 57 -57 = inner angle x
66 = x , so that inside angle on the isosceles is 66°
that's great to know, that angle is also part of the bigger triangle that goes outside the circle and I'm pretty sure the angle that is at the top of the triangle , at least in the picture, is a right angle or 90° sooo we now know two angle of the triangle and can figure our the "?" one. :)
180 = 66 + 90 + ?
180-66-90 = ?
24 = ?
so that angle at the point with the "?" is 24 ° :)
2)
The given angle is 24° :0 look above.. that last we we solved was also 24°
everything is the same in drawing 2, as in drawing 1. We can simply use all the things we know about drawing 1.. The inside angle at the center of the circle will be 66 ° and the two angle out by the perimeter of the circle will be 57° just like in drawing 1. They made that a little too easy :D Le'ts hope we get a few more like that :)
3)
I'm just sure why the drew the circle in this drawing. we don't need it to solve this triangle. Maybe you're not supposed to use this very common way to solve the triangle yet? but maybe it's good to introduce it anyway? since we are given the hypotenuse (long side) and the adjacent side (next to) the angle we can just use SOH CAH TOA to find any angle or side of this triangle. I'll put the useful remind of how trig functions ( sin, cos, ect.) fit on triangles and then we'll use them to find the parts we want. :)
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
copy the above down. and put in in a handy place on your computer , for quick reference any time you have to solve a triangle. it's really super helpful :)
okay now look at the triangle in question 3) what do we know, and what do we want to find? we know the Hyp and Adj and one angle and want to find the Opposite (Opp) side from the known angle. sooo we have a choice of SOH or TOA.. let's use SOH,
SOH ⇒ Sin(Ф) = Opp / Hyp
Sin(53) = Opp/ 10
algebra skill engage :P
10* Sin(53) = Opp
7.9863551 = Opp
so that side with the question mark is 8.0 long. ( rounded to nearest 10th)
4)
On this triangle we are given the Opp and the Adj sides and an angle and are asked to find the Hyp
which trig function would you like to use?
Let's use CAH this time. We could also use SOH , but we just used that one. let's try out the "tools" of the trade :)
CAH ⇒ Cos(Ф) = Adj / Hyp
Cos(37) = 8/Hyp
use algebra skillz
Hyp = 8 / Cos(37)
use calculator to find Cos(37) :/
Hyp = 10.01708
? = 10.0 ( rounded to nearest 10th )

oh for this one we do need the circle, and I don't know why they want people to know this , nobody uses this math :? Anyway,
there is a confusing formula for this type of problem
∠ = (bigger arc - smaller arc ) / 2
since we're given the 65° , we know that 2*65= 130 which is the angle of the bigger arc - smaller arc = 130 °
now we have to use our really keen algebra skillz to see that
if the total all the way around a circle is 360 and we have 130 of those left so
eq. 1) 360 = big arc + small arc
then
360-smal arc = big arc
and
eq. 2) 130 = big arc - small arc
plug in for "big arc" what we know from above :P
130 = 360-small arc - small arc
130 = 360 - 2small arc
130 + 2 small arc = 360
2 small arc = 230
small arc = 115
:0 wow.. we solved it.. that was a lot of fancy algebra huh :P
? = 115° ( the small arc)
6)
same as 5
given 72°
72*2=144°
eq. 1) 360 = big arc + small arc
eq. 2 ) 144 = big arc - small arc
solve for big arc this time
360-bigl arc = small arc
now plug into eq. 2
144 = big arc - (360-big arc)
144 = big arc - 360 + big arc
144 = 2big arc - 360
144+ 360 = 2 big arc
504 = 2 big arc
252° = big arc
yay solved !! phew.. that was a lot of algebra.. :P
