Answer:
A = 10W - W²
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
Area of a rectangle =LW
L is the length
W is the width
Given
Perimeter = 20m
20 = 2 (L+W)
10 = L+W
L = 10 - W ....2
Substitute equation 2 into the formula for calculating the area
Recall that A = LW
A = (10-W)W
A = 10W - W²
Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²

If ∠5 = 137° and ∠7 = 100°, find the measure of ∠1. *
Answer:
m∠1 = 37°
Step-by-step explanation:
if m∠5 = 137 then m∠2 = 43 (supplementary angles)
if m∠7 = 100 then m∠3 = 100 (vertical angles)
m∠1 + m∠2 + m∠3 = 180°
m∠1 + 43 + 100 = 180°
A sphere has a volume of approximately 24,416.64 cubic inches (using 3.14 for ).
The diameter of the sphere is ___ inches.
Answer:
diameter = 36 in.
Step-by-step explanation:
V = 4π r^3/3
24416.64 = (4(3.14) r^3)/3
73249.92 = 12.56 r^3
r^3 = 5832
r = cube root of 5832 = 18
diameter = 36 in.

Point B is a point of tangency. Find the radius r of OC.
Answer:
r = 16 units
Step-by-step explanation:
From the figure attached,
AB is the tangent drawn from a point A to the circle C.
BC = r [Radius of the circle]
Length of AC = (18 + r)
AB = 30
By the property of a tangent drawn to a circle,
"Radius of a circle and tangent are perpendicular to each other"
AB ⊥ BC
By applying Pythagoras theorem in ΔABC,
AB² + BC² = AC²
(30)² + r² = (r + 18)²
900 + r² = r² + 36r + 324
36r = 900 - 324
r = [tex]\frac{576}{36}[/tex]
r = 16 units

At summer camp, the cook asks 6 campers to help with slicing watermelons. Each camper slices 4 ½ watermelons. How many melons do the campers slice?
Answer:
27 melons
Step-by-step explanation:
Number of melons sliced = Number of melons sliced by each camper * number of campers
= 4 1/2 * 6
[tex]= \frac{9}{2}*6\\\\=9*3\\\\= 27[/tex]
Answer:
Solution :-No. of campers = 6
Melon slice by 1 camper = 4½
Total melons sliced = 4 ½ × 6
Total melons sliced = 9/2 × 6
Total melons sliced = 9 × 3
Melons sliced = 27★

After eight games the team has won two games lost five and tied one if there season is 24 games how many games will they win at this rate
Answer:
Since the games in total add up to 8, we see that 8 is a factor of 24. It goes in 3 times. Therefore, we have to multiply everything by 3 to get the answer out of 24. There will be 6 wins, 15 losses and 3 tie. That adds up to 24.
Timia needs so cash in a hurry she owns her car outright and is considering a title loan. The lender told timia she could borrow 1750 for 1 month
The question is incomplete ; the fee which Timia would pay isn't given. And this is needed to compute the APR on the loan.
I would assume that the fee which Timia would pay as interest on the 1 - month loan is x
Answer:
r = x / 145.83333
Step-by-step explanation:
If interest paid, I = x
Principal, P = $1750
And period (time) of loan = 1 month = (1/12) = 0.0833333
Rate = r
Using the simple interest formula :
Interest = Principal * rate * time
x = 1750 * r * 0.833333
Make r the subject :
x = 145.83333r
Divide both sides by 145.83333
Hence, the rate value , r becomes :
r = x / 145.83333
Therefore, the student can just input the appropriate, interest value in place of x and obtain the correct and exact answer (I do not want to use an hypothetical value for x) .

What is a circle?A circle is a locus of a point that moves in a plane such that its distance from a fixed point remains constant.
Connect A to D
So, ∠BAC=53°
From the congruence of triangles
∠BAD=∠CAD =53/2 = 26.5°
Also, ∠BAD=∠ABD (since AD=BD=radius)
So, ∠BDA + ∠BAD + ∠ABD=180°
10x-23 + 26.5+26.5 = 180
10x+30=180
10x=150
x=15°
Hence, Using the congruence of triangles, the value of x comes to be 15°

j = -8/11
geometric figure it is called a line.
Step-by-step explanation:
Expand the following:
4 (6 j + 5 j + 8)
Grouping like terms, 5 j + 8 + 6 j = (5 j + 6 j) + 8:
4 (5 j + 6 j) + 8
5 j + 6 j = 11 j:
4 (11 j + 8)
4 (11 j + 8) = 4×8 + 4×11 j:
4×8 + 4×11 j
4×8 = 32:
32 + 4×11 j
4×11 = 44:

Malia and Omar want to find the shortest route from their school to a local burger
hangout. The length of Route A is 1.5 times the length of Route B and ¾ the
length of Route C. If Route C is 3 kilometers long, then Route A is how many
kilometers longer than Route B?
Answer:
Route A is 0.75 km longer than route B.
Step-by-step explanation:
Length of route A is 1.5 times the length of route B.
a = 1.5b
[tex]\frac{a}{b}=\frac{15}{10}[/tex]
[tex]\frac{a}{b}=\frac{3}{2}[/tex] --------(1)
Here, a = Length of route A
b = Length of route B
Length of route A is [tex]\frac{3}{4}[/tex] of route C.
a = [tex]\frac{3}{4}c[/tex]
[tex]\frac{a}{c}=\frac{3}{4}[/tex] ------(2)
Here, c = Length of route C
Length of route C = 3 km
Length of route A = [tex]\frac{3}{4}\times 3[/tex] [From equation (2)]
= 2.25 km
Length of route B = [tex]\frac{2}{3}\times 2.25[/tex] [From equation (1)]
= 1.5 km
Difference in route A and route B = 2.25 - 1.5
= 0.75 km
Therefore, route A is 0.75 km longer than route B.
