Answers

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

Answer: A( 148 meters )

Answer:

Choice A

Step-by-step explanation:

Using vertical angles, you know the side under the top 20 meters is also 24 meters. Then the most bottom side of the lower garden is 30 meters. You have 30+30+20+20+24+24=2(30)+2(20)+2(24)=2(30+20+24)=2(74)=148. Thus, choice is correct.

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?

Answers

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

What is the 37th term of the arithmetic sequence with the first term -39 and the common difference of 8.

Answers

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 = 8

Plug those into the formula:

[tex]a_{37}=-39+(37-1)8[/tex]

Then solve:

[tex]a_{37}=-39+(36)8\\a_{37}=-39+288\\a_{37}=249[/tex]

27 x 9^3x can be written in the form 3^k where k is an expression in terms of x. Find k

Answer:

a = 45°

Step-by-step explanation:

In triangle PSR

PS = RS (Given)

angle SPR = angle SRP (isosceles triangle property)

Let angles SPR and SRP be x

Therefore, 90° + x + x = 180° (angle property)

=> 90° + 2x = 180°

=> 2x = 180° - 90° = 90°

=> 2x = 90°

=> x = 90° ÷ 2 = 45°

=> x = 45°

Divide x5+15x4+54x3−25x2−75x−34 by x+8

Answers

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.
