b is directly proportional to a.
b is 10 when a is 8.
Work out b when a is 9.
Answer:
B=11
Step-by-step explanation:
b=10 a=8
b=? a=9
Either you can cross multiple 10x9=90/8 (11.25, round down to 11), or you can look that 9 is 8+1, so of we do the same process to b then we would find our awnser. 10+1=11.
When a is 9 then, the value of b will be;
⇒ b = 45/4
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
'b' is directly proportional to a.
And, b is 10 when a is 8.
Now,
Since, 'b' is directly proportional to a.
Hence, We get;
⇒ b = ka
Where, k is constant of proportionality.
Here, b is 10 when a is 8.
So, Put b = 10 and a = 8;
⇒ b = ak
⇒ 10 = k × 8
⇒ k = 10 / 8
⇒ k = 5/4
So, When a is 9 and k is 5/4, then;
⇒ b = ak
⇒ b = 9 × 5/4
⇒ b = 45/4
Thus, The value of b = 45/4

A rectangular park measures 100m by 60m. A path of constant width is to be paved around the perimeter. The mayor wants to ensure that the resulting area is 6400m2. Find the width of the path. (Round to the nearest tenth.)
Answer: 20
Step-by-step explanation:
First let's find the perimeter: 2(l+w) = 2 (100 + 60) = 2 (160) = 320m
Now let's divide 6400 by 320 = 20 metres
The constant width of the path is 20 m.
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
Length of park = 100 m
Breadth of park = 60 m
As, the area including the path = 6400 m²
Area of path + Area of width = 6400 m²
100 x 60 + Area of width = 6400
Area of width = 400 m²
Area of width = 20 x 20 m²
Thus, the width of path is 20 m.

Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))
Answer:
x=10.247
y=52.02
z=37.98
Step-by-step explanation:
For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.
For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle
For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

Answer:
add a point 4 units to the left
Step-by-step explanation:
Answer:
Add a point 5.5 units right of 1
Step-by-step explanation:
I used a ruler, and found out that the distance between 0 and 1 is 1cm. The distance between 0 and x is 2.5cm. Since x is to the left of 0, x = 2.5.
4 - -2.5 = 4 + 2.5 = 6.5, or 6.5 units right of 0, which is the same as 5.5 units right of 1.

Answer:
y = 20 + 35x or y = 35x + 20
Step-by-step explanation:
Looking at the problem, a cell phone company charges $20 for a new account, and $35/month for phone service. With that information we can quickly form this equation:
y = 20 + 35x
The y is the total cost, 20 is the initial charge, and 35x is the per-month charge.
What is below is the graph for this equation.

This cylinder has a volume of 12cubic inches and a diameter of 4 inches.
Find the cylinder's radius and height.
h
Answer:
0.9554
Step-by-step explanation:
d = 4
r = d/2
r = 4/2
r = 2
V = 12
V = pi r^2 h
V = 3.14 * 2^2 * h
12 = 3.14 * 4 * h
12 = 12.56 * h
h = 12 / 12.56
h = 0.9554

What is the least common denominator of
1/3 and 5/9
Answer:
LCD = 9Equivalent Fractions with the LCD
1/3 = 3/9
5/9 = 5/9
Solution:
Rewriting input as fractions if necessary:
1/3, 5/9
For the denominators (3, 9) the least common multiple (LCM) is 9.
LCM(3, 9)
Therefore, the least common denominator (LCD) is 9.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/3 = 1/3 × 3/3 = 3/9
5/9 = 5/9 × 1/1 = 5/9

Answer:
x^2 + 11x + 18.
Step-by-step explanation:
The length = x + 9 and the width = x + 2.
So the area
= length * width
= (x + 9)(x + 2)
= x(x + 2) + 9(x + 2)
= x^2 + 2x + 9x + 18
= x^2 + 11x + 18.

∛(x-2)=0
∛(x-2)=0 -Set the radicand equal to 0
x-2=0

Why is the number that satisfies this equation not a real number?
x^2=--1
Answer:
I assume that says [tex]x^2=-1[/tex], but that is the case because when we square a number, we can NEVER get a negative number. The smallest square we can get is 0. 1^2 is 1, and no real number squared gives us a negative number.
