help po plsss
Answer:
9.42 m
6.28m
Step-by-step explanation:
to determine the distance walked, calculate the circumference of the circular pool
circumference of a circle = πD
π = 3.14
D = diameter
3 x 3.14 = 9.42 m
Difference in circumference = π( diameter of bigger circle - diameter of smaller circle)
diameter of smaller circle = 5 x 2 = 10
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x ( 12 - 10) = 6.28

If x varies directly as y and x = 74 when y = 10, find x when y = 4.
Answer:
The value of x is 21 .
Step-by-step explanation:
We are given that x varies directly as y
--- A
We are given that x = 7 and y = 28
Substitute the values in A
7 = 28k
Now equations becomes :
y = 84
Hence The value of x is 21 .

3(n+4)=21 what does n =?
Answer:
3.
Step-by-step explanation:
3(n + 4) = 21
3n + 12 = 21
3n = 21 - 12 = 9
n = 3.
Answer:
n = 3
Step-by-step explanation:
Given
3(n + 4) = 21 ( divide both sides by 3 )
n + 4 = 7 ( subtract 4 from both sides )
n = 3

[tex]find \: the \: area \: of \: cylinder \: \\ \\ height \: = 4cm \\ \\ base \: radius \: = 6cm \\ \\ [/tex]
Answer:
Curved Surface Area = 48π cm² (≈ 150.72 cm²)
Total Surface Area = 120π cm² (≈ 376.8 cm²)
Step-by-step explanation:
GIVEN :-
Height of cylinder = 4 cmBase radius = 6 cmTO FIND :-
Area of cylinderGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
Curved Surface Area of cylinder = 2πrh
Total surface Area of cylinder = 2πrh + 2πr² = 2πr(h + r)
SOLUTION :-
Curved Surface Area of cylinder = 2×π×6×4 = 48π cm² ≈ 150.72 cm²
Total Surface Area of cylinder = 2×π×6(4 + 6) = 120π cm² ≈ 376.8 cm²

Determine the amount of space ( volume) he’s allowed for the potted plant in the bottom of the greenhouse who shape is a rectangle or prism. ❤️
Answer:
A. Volume is 2400 feet^3
B. 1413.7 feet ^3
C. 3814 feet^3
Step-by-step explanation:
given = a rectangular prism having l=8 feet w=12 feet h=25 feet
to find volume
v = l * w * h
v = 8x12x25
v = 2400 feet^3
what’s the volume ??
no links
Question:
What’s the volume ?
Answer:
Volume: 8663.2
Area : 392
Step-by-step explanation:
The formula for volume is length times width times height (L x W x H)
So
28 x 28 = 784 x 22.1 = 17326.4 (Crazy right) But this is not the answer. A triangle is half of a Square so we divde by 2
17326.4 / 2 = 8663.2
The Volume is 8663.2
And if you are looking for the Area it's 392

What is the total payment
required to pay off a promissory
note issued for $500.00 at 10%
ordinary interest and a 180-day
term?
Answer:
the total payment need to pay is $525
Step-by-step explanation:
Given that
The amount at promissory note issued is $500
The rate of interest is 10%
And, the time period is 180 days
So, the total payment included is
= $500 + ($500 × 10% × 180 days ÷ 360 days)
= $500 + $25
= $525
hence, the total payment need to pay is $525

Step-by-step explanation:
2(x + 10) = -60 solve for x
Answer:
2x + 20 = -60
-20 -20
2x = -80
Divide by 2 on both sides.
X = -40
Answer:
-40
Step-by-step explanation:
2(x + 10) = -60
step 1 distribute the 2 to the x and 10
2 * x = 2x
2 * 10 = 20
we now have 20 + 2x = -60
step 2 subtract 20 from each side
20 - 20 cancels out
-60 - 20 = -80
we now have 2x = -80
step 3 divide each side by 2
2x / 2 = x
-80 / 2 = -40
we're left with x = -40
At the Galapagos Islands, Dr. Owen finds 102 giant tortoise eggs that he brings back to his research center to be hatched in safety. At the research center, six of the eggs hatch, and the hatchlings are placed in a nursery. Dr. Owen places equal but unknown numbers of the remaining eggs in eight different labs.
Which of the following equations best represents this situation?
Question 5 options:
8x-6=102
102x=8-6
6x+8=102
8x=102-6
Answer:
8x-6=102
Step-by-step explanation:
8x the remaining eggs in 8 different labs and the 6 that are placed in the lab and the total is 102 so 8x-6=102
