30/x = 54/81 what value does x have to be to make it true
Answer:
x=45
Step-by-step explanation:
30/x = 54/81
30 = 54/81(x)
x = 30 ÷ 54/81
x=45
Answer:
x = 45
Step-by-step explanation:
30/x = 54/81
~Cross multiply
30 * 81 = 54 * x
~Simplify
2430 = 54x
~Divide 54 to both sides
45 = x

3. Kyle and Michael a rup a lap around a track. Kyle gets a 50 a meter head start and runs 3 meters
per
second. Michael runs at a speed of 4 meters per second. How long will it take for Michael
to reach Kyle?
Answer:
50 second
Step-by-step explanation:
let the distance between Michael and kyle (s)
s= 50 m
we want to know how long it takes for Michael(speed 4 m/s ) to reach kyle(3m/s)
v = s/t
t = s/v
Vm = speed of Micheal
Vk = speed of kyle
v = ( Vm - Vk )
t = 50/(4-3) = 50 second

Divide x5+15x4+54x3−25x2−75x−34 by x+8
Step-by-step explanation:
Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of 0.
x+8x5+15x4+54x3-25x2-75x-34
Divide the highest order term in the dividend x5 by the highest order term in divisor x.
x4x+8x5+15x4+54x3-25x2-75x-34
Multiply the new quotient term by the divisor.
x4x+8x5+15x4+54x3-25x2-75x-34+x5+8x4
The expression needs to be subtracted from the dividend, so change all the signs in x5+8x4
x4x+8x5+15x4+54x3-25x2-75x-34-x5-8x4
After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.
x4x+8x5+15x4+54x3-25x2-75x-34-x5-8x4+7x4
Pull the next terms from the original dividend down into the current dividend.
x4x+8x5+15x4+54x3-25x2-75x-34-x5-8x4+7x4+54x3
Divide the highest order term in the dividend 7x4 by the highest order term in divisor x.
On dividing, x⁵+15x⁴+54x³−25x²−75x−34 by x+8, Quotient is x⁴+7x³−2x²−9x−3 and Remainder is -10.

27 x 9^3x can be written in the form 3^k where k is an expression in terms of x. Find k
Answer:
27 x 9^3x = 3^3 x 9^3x = 3^3 x (3^3)^3x = 3^3 x 3^9x = 3 ^3+9x
3^3+9x = 3k
ln(3^3+9x) = ln(3^k)
3+9x(ln3)=k(ln(3))
k= 3(1+3x)/ln(3)

2) Find the area and perimeter of a semi -circular disc whose radius is 10cm. (take π = 3.14)
Answer:
Area =Pi r2=3.14×10x10
=3.14×100cm2
=3.14cm2
Perimeter = 2 pi r
=2 ×3.14×10
=6.28cm
Or =Pi d
= 3.14 ×20cm
=62.8cm
Note:R means radius
D means diameter
radius is half of a diameter e.g radius is10 and diameter is 20

Answer:
- 5 ≤ x < 3
Step-by-step explanation:
The lower limit has a solid circle at - 5
This means that x can equal - 5
The upper limit has an open circle at 3
This means that x cannot be equal to 3
The inequality represented by the diagram is then
- 5 ≤ x < 3

How many solutions does 7( X -5 ) = X +13
Answer:
x=8 (one solution)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7(x−5)=x+13
(7)(x)+(7)(−5)=x+13(Distribute)
7x+−35=x+13
7x−35=x+13
Step 2: Subtract x from both sides.
7x−35−x=x+13−x
6x−35=13
Step 3: Add 35 to both sides.
6x−35+35=13+35
6x=48
Step 4: Divide both sides by 6.
x=8
Answer:
x = 8 (one solution)
Step-by-step explanation:
7x - 35 = x + 13
-x -x
6x - 35 = 13
+35 + 35
6x = 48
divided by six on both sides
x = 8

What is the 37th term of the arithmetic sequence with the first term -39 and the common difference of 8.
Answer:
[tex]a_{37}=249[/tex]
Step-by-step explanation:
A sequence that has a common difference is an arithmetic sequence:
[tex]a_n=a_1+(n-1)d[/tex]
where aₙ is the nth term, n is the index, and d is the common difference.
In your question:
n = 37a₁ = -39d = 8Plug those into the formula:
