Answer:
Volume = 4/3 * PI * radius^3
Volume = 4/3 * PI * 12.3^3
Volume = 1.33333333 * 3.14159265* 1860.867
Volume = 7794.7814531034

When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.
How far, in metres, is it from my home to my school?
Given:
I have walked 20% of the way to school.
I have 1200 metres more to walk than when I have 20% of the walk remaining.
To find:
The distance from home to school.
Solution:
Let x be the distance from home to school.
I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.
It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.
[tex]1200=\dfrac{60}{100}x[/tex]
[tex]1200=0.6x[/tex]
[tex]\dfrac{1200}{0.6}=x[/tex]
[tex]2000=x[/tex]
Therefore, the distance from home to school is 2000 metres.
How far, in metres, is it from my home to my school is 2,000 metres.
First step is to formulate
1200/(1-2×20%)
Second step is to find how far in metres
Distance=1200/(1-0.4)
Distance=1200/0.6
Distance=2,000
Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.

An aquarium holds 11.39 cubic feet of water, and is 2.3 feet long and 1.8 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
2.75feet
Step-by-step explanation:
Given data
Volume= 11.39 cubic feet
Length= 2.3 feet
Width= 1.8 feet
Depth= ???
The expression for the volume is
Volume= Length*Width*depth
11.39=2.3*1.8*d
11.39=4.14d
d= 11.39/4.14
d= 2.75
Hence the depth is 2.75feet

Answer:
Volume: 762 in³
LA: 448 in²
SA: 544 in²
Step-by-step explanation:
So first, the volume, the formula to find the area is base x height, so we have to find the base first:
8 x 12 ÷ 2 = 48
48 x 14 = 672
So the volume of the prism is 762 in³
Now, the lateral area, which is basically the surface area without the bases, or, in this case, the triangles:
10 x 14 = 140 x 2 = 280
12 x 14 = 168
168 + 280 = 448
So the LA = 448 in²
Now, for the surface area:
12 x 8 = 96 (usually, it would then be ÷ 2, but because there are two triangles, it isn't necessary)
96 + 448 (the LA) = 544
So the SA = 544 in²

Solve the 2x^2 - 5 = 13
Answer:
x=3
x=−3
Step-by-step explanation:
2x^2 - 5 = 13
Subtract 13 from both sides.
2x^2 - 5 - 13 = 0
Subtract 13 from −5 to get −18.
2x^2 - 18 = 0
Divide both sides by 2.
x^2 - 9 = 0
Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).
(x−3)(x+3)=0
To find equation solutions, solve x−3=0 and x+3=0.
x=3

There are 300 calories in three ounces of a certain ice cream. How many calories are there in two pounds?
Answer:
3200
Step-by-step explanation:
1 pound = 16 ounces.
300 = 3 ounces.
2 pounds = 32 ounces.
If 300 calories are in 3 ounces, how many are in 32 ounces?
32 / 3 = 10 2/3

Round to the nearest tenth. Use 3.14 or 22/7 for π.
Note: Consider we need to find the circumference and area of the given circle.
Given:
A circle with radius 7.1 m.
To find:
The circumference and area of the given circle.
Solution:
Circumference of a circle is:
[tex]C=2\pi r[/tex]
Putting [tex]r=7.1,\pi=3.14[/tex], we get
[tex]C=2(3.14)(7.1)[/tex]
[tex]C=44.588[/tex]
[tex]C\approx 44.6[/tex]
Therefore, the circumference of the circle is 44.6 m.
The area of the circle is:
[tex]A=\pi r^2[/tex]
Putting [tex]r=7.1,\pi=3.14[/tex], we get
[tex]A=3.14(7.1)^2[/tex]
[tex]A=158.2874[/tex]
[tex]A\approx 158.3[/tex]
Therefore, the area of the circle is 158.3 sq. m.
The regular pentagon shown has an apothem with a length of 2 centimeters. To the nearest tenth, what is the area of the regular pentagon in square cintimeters
Answer:
11.8cm²
Step-by-step explanation:
The area of the regular pentagon is expressed as;
A = pa/2
p is the perimeter of the pentagon
a is the apothem
Since p = 5s
s is the side length, hence;
A = 5sa/2
Get the side length s;
central angle = 360/5
central angle = 72degrees
angle in the right angle triangle =72/2 = 36degrees
Using SOH CAH TOA
sin 36 = x/2
x = 2sin36
x = 1.1755
s = 2x
s = 2.35cm
Get the area
A = 5(2.35)(2)/2
A = 5(2.35)
A = 11.8cm²
Hence the area of the regular pentagon is 11.8cm²
Answer:
11.8cM

Which statement describes the relationship between x and y? O As x increases, y decreases. O As x increases, y increases. O As x increases, y increases and then decreases. O As x increases, y decreases and then increases. X х
Answer:
d
Step-by-step explanation:
The value of the modulus function is y = | x | - k , and as x increases , the value of y decreases and then increases
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the modulus function be represented as A
Now , the value of A is
y = | x | - k
where k is the factor of diminish
Now , when k = 4
The value of the modulus function is y = | x | - 4 and the graph is plotted
And , as x increases , the the value of y decreases and then increases
So , If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Hence , the modulus function is y = | x | - k

hassan and eva rode their bikes from the same starting point. Hassan rode his bike 5/6 of a mile, while eve rode hers 4/7 of a mile. which equation shows the mileage difference D in the distance they rode
Answer:
A
Step-by-step explanation:
5/6 > 4/7 so you'd have to subtract from 5/6 to even get to 4/7.
The equation for the mileage difference is 5/6 - d = 4/7.
What are expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:
(Mathematical Operator, Number/Variable, Expression)
Given the distance covered by Hassan = 5/6 of mile
distance covered by Eva = 4/7 of mile
5/6 = 0.833
4/7 = 0.57
since Hassan has covered more distance than Eva
so equation is 5/6 - d = 4/7
Hence option A is correct.

B.(11, 4)
C.(13, 18)
D.(1.5, -2)
Answer:
The coordinates of the midpoint between the two
points is (-1,4)
Step-by-step explanation:
Here, we want to find the midpoint between the two given points
To do this, we are to use the midpoint formula
We have this as;
m = (x1 + x2)/2, (y1 + y2)/2
(x1,y1) = (-7,9)
(x2,y2) = (5,-1)
(x,y) = (-7 + 5)/2, (9-1)/2
= (-2/2, 8/2) = (-1,4)
