Answer and Step-by-step explanation:
First, get theta by itself.
θ = [tex]sin^{-1}(\frac{\sqrt{3} }{2} )[/tex]
Plug this into a calculator.
θ = 60°
To get it in radians, multiply 60 by [tex]\frac{\pi }{180}[/tex].
θ = [tex]\frac{1}{3} \pi[/tex] radians

a strawberry cake is cut into three pieces. The Arc measures of all three pieces are congruent. What is the measure of angle XYZ
Answer:
I think the strawberry cake measure have to be 360⁰. so the arc measure is 360⁰÷3=100
so we have all three arcs congruent b/c all measures 100⁰
I think XYZ=100⁰
Step-by-step explanation:
solution given:
a strawberry cake is cut into three pieces
since
Arc measures of all three pieces are congruent
all 3 arc are equal
So it forms a equilateral TRIANGLE
each angle of equilateral triangle is 60°
So,measure of angle XYZ is 60°.

Step-by-step explanation:
In triangle ABD,
ang.ABD=90°
AB=9 cm
AD=15 cm
Now,
Using Pythagoras theorem,
AD2=AB2+BD2(2=square)
or,152=92+BD2
or,225=81+BD2
or,225-81=BD2
or,144=BD2
or,BD=12 cm
Then,
In triangle CBD,
CD=5 cm
BD=12 cm
BC=?
Now,
Using Pythagoras theorem,
BC2=CD2+BD2
or,BC2=52+122
or,BC2=25+144
or,BC2=169
or,BC=13 cm

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
Answer:
240
Step-by-step explanation:
1/5
0.75 = 3/4
1/5 + 3/4 = 19/ 20
1 - 19/20 = 1/20
therefore 12 mango equal 1/20
12 × 20 = 240
12/240 is the same as 1/20
Can some one help me.
Answer:
The slope is 3
Step-by-step explanation:
m = rise/run
m = (y2 - y1)/(x2-x1)
points: (0,-5), (1,-2)
m = ((-5) - (-2))/ ((0) - (1))
m = (-5 + 2)/ (-1)
m = -3/-1
m = 3
Consider this cone.
A cone with radius 4 and slant height of l.
Which statements about finding the surface area of the cone are true? Check all that apply.
The surface area is the sum of the lateral area and the base area.
The slant height is the distance from the center of the circular base to the vertex.
The lateral area is the area of the curved surface of the cone.
The lateral area can be found using the equation LA = Pirl.
The base area can be found using the equation B = r2.
Please dont answer unless you know it. Edge 2021.
Answer:
1)The surface area is the sum of the lateral area and the base area.
3)The lateral area is the area of the curved surface of the cone.
4)The lateral area can be found using the equation LA = Pirl.

Find the perimeter of the figure to the nearest hundredth.
The distances and times from a track meet for four schools are shown.
School has the fastest average time per mile at the track meet.
Answer:
Average time for West Middle was maximum.
Step-by-step explanation:
Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]
For Eastbay Middle,
Average time per mile = [tex]\frac{42}{7}[/tex]
= 6 minutes per mile
For Northwest Middle,
Average time = [tex]\frac{25}{5}[/tex]
= 5 minutes per mile
For South Central Middle,
Average time = [tex]\frac{28}{4}[/tex]
= 7 minutes per mile
For West Middle,
Average time = [tex]\frac{48}{6}[/tex]
= 8 minutes per mile
Therefore, average time for West Middle (8 minutes per minute) was maximum.
In the triangle below,
Step-by-step explanation:
4x -20 + 3x +12 = 90
7x -8 = 90
7x = 98
x = 14
Angle F: 4(14) -20 = 36
Angle E: 3(14)+12= 54
Angle G : 90

ill give u the crown thingy pls help
Answer:
y=18 x=15
Step-by-step explanation:
1.
multiplyboth sides by 3
2(x-6)=18
divide both sides by 2
x-6= 9
add 6 on both sides
x=15
2.
add 6 on both sides
2/3y= 12
multiply both sides by 3
2y=36
divide both sides by 2
y=18
Daniel deposits a certain sum of money in a bank. If the simple interest rate of the bank decreases from 3.75% per annum to 3.5% per annum, Daniel's interest will increases by $50 in a year. Find the sum of money he deposits.
The answer is $20000 but I don't understand how. Please give a step-by-step explanation.
Answer: $20,000
Step-by-step explanation:
Given
Interest decreases from 3.75% to 3.5% in a year
This change in the rate of interest brings a yield of 50$
Earlier interest was
[tex]S.I_e=\dfrac{P\times 3.75\times 1}{100}[/tex]
Now, interest is
[tex]S.I._n=\dfrac{P\times 3.5\times 1}{100}[/tex]
change gives 50$ i.e.
[tex]\Rightarrow \dfrac{P\times 3.75\times 1}{100}-\dfrac{P\times 3.5\times 1}{100}=50\\\\\Rightarrow \dfrac{P\times (3.75-3.5)\times 1}{100}=50\\\\\Rightarrow P=\dfrac{50\times 100}{0.25}=\$20,000[/tex]
Which statement best describes the equation
y = 5 - 5x?
A. The equation does not represent a function.
B. The equation represents a function, but not a linear function.
C. The equation represents a linear function.
D. The equation represents a line, but not a linear function.
Answer:
The equation represents a linear function because the equation has two variables, x and y.

Step-by-step explanation:
Consider a collection of envelopes consisting of 3 red envelopes, 1 blue envelope, 2 green envelopes, and 3 yellow envelopes. If two envelopes are selected at random, with replacement, determine the probability that at least one envelope is a red envelope.
Answer: The probability that at least one of the envelopes is red is 1/9 (simplified) or 9/81.
Step-by-step explanation:
There are a total of 9 envelopes. If two are selected at random with replacement the probability for both envelopes is 3 / 9 or 1/3. Since there are two you would do 1/3 * 1/3 to get 1/9 or 3/9 * 3/9 to get 9/81.

£760 is divided between Stephen, Bridget & Caroline so that Stephen gets twice as much as Bridget, and Bridget gets three times as much as Caroline. How much does Bridget get? £
Answer: Out of £750 and 3 bums
Caroline = 225
Bridget = 225 * 3 = 675
Step-by-step explanation:
Answer:
£228Step-by-step explanation:
Given:
Total = £760Stephen = s, Bridget = b, Caroline = cWe have equations:
s + b + c = 760b = 3cs = 2bSubstitute s with b and b with c as above into first equation:
2(3c) + 3c + c = 7606c + 4c = 76010c = 760c = 76Find b:
b = 3*76 = 228Bridget gets £228
Students were asked to vote for the leisure activity they liked best. The data are shown in the table. A 2-column table with 5 rows. Column 1 is labeled Number of Votes with entries 18, 22, 34, 28, 8. Column 2 is labeled Leisure Activity with entries Reading, Watching movies, Playing video games, playing sports, Other. Which statements are true? Check all that apply. A total of 34 students voted. The longest bar on a bar graph would be for the “Playing video games” category. The bars for “Watching movies” and “Playing sports” would be the same length. It would be time-consuming to show the data in a line plot because the data values are large. A line graph could be used to effectively represent the data.

√(64÷√(98
please help thanks
and show work it would be deeply appreciated
Answer:
√(64÷√(98 = (4√2)/7
Step-by-step explanation:
The Sqrt(64) is equivalent to 8
And the Sqrt(98) is equivalent to Sqrt(49) x Sqrt(2) also known as 7 Sqrt(2)
Now since we can't have a Square Root at the denominator we multiply it by Sqrt(2) on both the numerator and denominator
We now have 8Sqrt(2)/14 which can be simplified to (4√2)/7

Answer:
y=8-6x
Step-by-step explanation:
Answer:
y=0
x=4/3
Step-by-step explanation:
6x+y=8
x =8-y/6
substitute 8-y/6 in second equation
42*8-y/6 +7y=56
7(8-y) +7y=56
56-y+ 7y=56
-y+ 7y=0
6y=0
y=0
6x+y=8
6x+0=8
x=8/6
x=4/3
