Rate times time equals distance. R*t=d
Rate =124
Distance = 310

124*t=310
Divide both sides by 124
2.5 The answer is C

A triangle has side lengths of (7x-4)(7x−4) centimeters, (x+3)(x+3) centimeters, and (3y+2)(3y+2) centimeters. Which expression

Papessa [141]

Answer:

<u>This assumes that the question was meant to read:</u>

"A triangle has side lengths of (7x−4) centimeters, (x+3) centimeters, and (<u>3x+2</u>) centimeters." <u>And not </u>"A triangle has side lengths of (7x-4)(7x−4) centimeters, (x+3)(x+3) centimeters, and (3y+2)(3y+2) centimeters."

If the revision is correct, the perimeter is 11x + 1 cm

=============================================

<u>If the question was correctly written, then answer is:</u>

50x^2 - 50x + 9y^2 + 12 y + 29

===============

Step-by-step explanation:

(7x-4) cm

+ (x+3) cm

<u>+ (3x+2) cm</u>

11x + 1 cm

If the question was correctly written as is, then:

(7x-4)(7x−4) = 49x^2 - 56x + 16

+(x+3)(x+3) = + x^2 + 6x + 9

+(3y+2)(3y+2) = <u> +9y^2 + 12 y + 4</u>

50x^2 - 50x + 9y^2 + 12 y + 29 cm

What is the distance, to the nearest hundredth, from (6, 5) to (−3, −8)?

Olin [163]

Answer:

15.81

Step-by-step explanation:

Use the distance formula:

So the distance formula for two given points is

Distance= sqrt((x2-x1)^2 +(y2-y1)^2 ) =sqrt((-3-6)^2 +(-8-5)^2 )

=sqrt((-9)^2 +(-13)^2 )

=sqrt(81+169)

=sqrt(250)

=15.81

Hope this helped

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).

kramer

Given:

The sequence is:

$16,80,400,...$

To find:

The 6th term of the given sequence.

Solution:

We have,

$16,80,400,...$

Here, the first term is:

$a=16$

The ratio between consecutive terms are:

$\dfrac{80}{16}=5$

$\dfrac{400}{80}=5$

The given sequence has a common ratio 5. So, the given sequence is a geometric sequence.

The nth term of a geometric sequence is:

$a_n=a(r)^{n-1}$

Where, a is the first term and r is the common ratio.

Substitute $a=16,r=5,n=6$ to get the 6th term.

$a_6=16(5)^{6-1}$

$a_6=16(5)^{5}$

$a_6=16(3125)$

$a_6=50000$

Therefore, the 6th term of the given sequence is 50000.

If (a−8)/3=(a−3)/2 , then a = ?

Tresset [83]

Answer:

$\frac{(a - 8)}{3} = \frac{(a - 3)}{2} \\ 2(a - 8) = 3(a - 3) \\ 2a - 16 = 3a - 9 \\ 3a - 2a = - 7 \\ a = - 7$
