Answer:
2.19 ft
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
Surface area of the sphere = 60 ft²
The formula to find the radius of a sphere
= √A/4π
= √60/4 × π
= 2.19 ft
Therefore, the radius of the pinata = 2.19 ft
HELP WOTU FINDING CIRCUMFERENCE PLEASE 20 points!
Answer:
question 1 , area= 42.02 sq meter, circumference=22.98 meter
question 2, area=481.609sq meter, lenght of BC=263.3472 meter
for convience i converted yards to meter.
Step-by-step explanation:
in first question to find area of circle by multiplying value of pi (3.14) and square of radius of circle and to find circumference just multiply 2 with value of pi(3.14) and radius of circle.
in the second question to find area of sector use formula 1/2 r^2 x72 and to find lenght of arc bc use formula length= radius x 72

Frank was skiing down big bear mountain. He finished 22% of his skiing in the morning. Then he still had 23.4 miles left. How many miles did he ski in the morning?
Answer: 6.6 miles
Step-by-step explanation:
Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.
The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:
78% of x = 23.4
0.78 × x = 23.4
0.78x = 23.4
x = 23.4 / 0.78
x = 30 miles
Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:
= 30 - 23.4
= 6.6 miles

A rectangular plot measures 20 cm by 10 cm on a map. If is drawn to the scale 1:1000. What is the actual area of the piece of land in hectares ?
Answer:
Solution given:
length [l]=20cm
breadth [b]=10cm
area of rectangle =l×b=20×10=200cm²
since 1cm=1000cm
than real area =200×1000²=200000000cm²
since
1 hectares =10000m²=10000×10000=100000000cm²
so
200000000cm²=2hectares
So,actual area of the piece of land in hectares is 2 hectares.

What value of x and y makes the 2 triangles congruent by ASA? Find the measures of angle QPR and QRP
Given:
Two triangles congruent by ASA.
To find:
The the measures of x, y, angle QPR and angle QRP.
Solution:
The triangles PQR and PSR are congruent by ASA. So,
[tex]\angle QPR\cong \angle SPR[/tex]
[tex]PR\cong PR[/tex]
[tex]\angle QRP\cong \angle SRP[/tex]
Now,
[tex]m\angle QPR=m\angle SPR[/tex]
[tex]2x+1=x+18[/tex]
[tex]2x-x=18-1[/tex]
[tex]x=17[/tex]
And,
[tex]\angle QRP= \angle SRP[/tex]
[tex]8y-4=4y+28[/tex]
[tex]8y-4y=4+28[/tex]
[tex]4y=32[/tex]
Divide both sides by 4.
[tex]y=8[/tex]
The measure of angle QPR is:
[tex]m\angle QPR=(2x+1)^\circ[/tex]
[tex]m\angle QPR=(2(17)+1)^\circ[/tex]
[tex]m\angle QPR=(35+1)^\circ[/tex]
[tex]m\angle QPR=36^\circ[/tex]
And,
[tex]m\angle QRP=(8y-4)^\circ[/tex]
[tex]m\angle QRP=(8(8)-4)^\circ[/tex]
[tex]m\angle QRP=(64-4)^\circ[/tex]
[tex]m\angle QRP=60^\circ[/tex]
Therefore, the required values are [tex]x=17, y=8, m\angle QPR=36^\circ ,m\angle QRP=60^\circ[/tex].
Of the flags in Albert's Flag Shop, 1/10 are pink and another 1/2 are orange. What fraction of the flags are either pink or orange?
Answer: 6/10
Step-by-step explanation: The answer is 6/10 because: first you convert the 1/2 to tenths which would be 5/10. Then, you add 1/10 and 5/10 and you get 6/10 of the flags were either pink or orange.

Answer:
D. 2%
Step-by-step explanation:
The growth rate can be found by looking at the growth factor of the exponential function.
f(x) = (initial value) × (growth factor)^x
The growth rate is related by ...
growth factor = growth rate + 1
This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.
__
We can write the function g(x) describing the table as ...
g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))
So, this could be ...
g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x
where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor
This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.
__
Then the difference between the growth rates of the two functions is ...
4% - 2% = 2% . . . . . matches choice D

For this exponential function,
what is the output value (y),
when the input value (x) is 1?
y = 3 .6%
Answer:
(1, 3 )
Step-by-step explanation:
Substitute x = 1 into the equation
y = [tex]\frac{1}{2}[/tex] × [tex]6^{1}[/tex] = [tex]\frac{1}{2}[/tex] × 6 = 3
(1, 3 ) ← with output value y = 3
The required output value for the exponential function at x = 1 is y = 3.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
what is an exponential function?The function which is in format f(x) = where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
[tex]y = 1/2*6^x[/tex]
at x = 1
putting the value of the x in [tex]y = 1/2*6^x[/tex]
[tex]y = 1/2*6^1[/tex]
y = 6/2
y = 3
Thus, the required output value for the exponential function at x = 1 is y = 3.
