MP.1 Make Sense and Persevere Gary has $4. Mary has twice as many dollars
Andreas93 [3]

Answer:

  $16

Step-by-step explanation:

Gary has $4. (given)

Mary has twice as many dollars as Gary, so Mary has 2×$4 = $8.

Larry has 4 fewer dollars than Mary, so Larry has $8 -4 = $4.

Gary, Mary, and Larry together have $4 +8 +4 = $16.

Refer to the following distribution:Cost of Textbooks Frequency $25 up to $35 2 S35 up to $45 5$45 up to $55 7$55 up to $65 20 S
soldi70 [24.7K]

Answer:

Relative\ Frequency = 0.04

Step-by-step explanation:

Given

Cost of Textbooks ---- Frequency

$25 up to $35  -----      2

$35 up to $45 -------     5

$45 up to $55  -------    7

$55 up to $65   ------    20

$65 up to $75   ----   -- 16

Required

Determine the relative class frequency for the $25 up to $35 class

First, we need to get the total frequency

Total = 2 + 5 + 7 + 20 + 16

Total = 50

Next, is to write out the frequency of $25 up to $35 class

Frequency = 2

Divide this frequency by the total frequency; This gives the relative frequency

Relative\ Frequency = \frac{Frequency}{Total}

Relative\ Frequency = \frac{2}{50}

Relative\ Frequency = 0.04

Hence;

Ind the equation of the tangent line to 9x^2+16y^2=52 through (2, -1)
EastWind [94]
Here are the steps.

In order to get the answer, first we need to get the x and y value of the center of the circle by using the equation of a circle (x^2 + y^2 = r^2)

<span>The center is (-9, -4)</span>

Once you get the center point, find the equation of the line (in a form of a radius) from the center point to point (2, -1). Get the slope.

The slope from center to point (2, -1) is 11/3

Finally, get the negative reciprocal of the slope from the previous step and form the equation using slope-intercept form ( y=mx + b). Then, that's the equation of the tangent line.

The slope of the tangent line is -3/11
The equation is y = -3/11x - 5/11

MARK BRAINLIEST AND 12 POINTS
attashe74 [19]

Answer:

17

125

Step-by-step explanation:

exterior angle is equal to sum of interior opposite angle. so

( 2x + 6 ) + ( 5x ) = ( 8x - 11 )

7x + 6 = 8x - 11

x = 17

exterior angle = ( 8 * 17 ) - 11 = 125

umka2103 [35]

Answer:

n = 5, n = -7/2

Step-by-step explanation:

2n + 5 = l

n - 4 = w

A = l × w = 15

(2n + 5)(n-4) = 15

2n^2 - 8n + 5n - 20 = 15

2n^2 -3n - 35 = 0

(2n + 7)(n - 5) = 0

2n + 7 = 0      or       n - 5 = 0

n = -7/2          or       n = 5
