A bag of marbles contains 40 red marbles, 54 blue marbles, and 29 yellow marbles. Which of the following represents the ratio of

JulsSmile [24]

Answer:

$\frac{29}{40}$

Step-by-step explanation:

we know that

To find the ratio of yellow to red marbles, divide the numbers of yellow marbles by the number of red marbles

Let

x-----> the numbers of yellow marbles

y----> he number of red marbles

we have

$x=29, y=40$

$\frac{x}{y}=\frac{29}{40}$

Quick it is due in 30 mins plz do quick

Answer:

1. 69°

2. 97°

3. 145°

4. 150°

5. 128°

6. 74°

Step-by-step explanation:

To find the angle measure of the missing angle, we have to note that the angle measures of a quadrilateral will all equal up to be 360°.

If we know 3 out of the 4 angles and the sum of the angles, we can add up the angles we know then subtract that from 360.

Number 1:

$87+112+92=291$

$360-291=69$

Number 2:

$124+71+68=263$

$360-263=97$

Number 3:

$95+46+74=215$

$360-215=145$

Number 4:

$72+49+89=210$

$360-210=150$

Number 5:

$69+65+98=232$

$360-232=128$

Number 6:

$77+123+86=286$

$360-286=74$

Hope this helped!

What is the equation of a line, in general form, that passes through point (1, -2) and has a slope of 1/3. 1.x - 3 y - 7 = 2.x -

Nutka1998 [239]

Answer:

x- 3y - 7=0

Step-by-step explanation:

the line in the slope-intercept form:

y= mx+b

m= 1/3 and point given (1, -2) by using which we find y-intercept:

b= y-1/3x
b= -2- 1/3*1= - 7/3

y= 1/3x- 7/3

General form of a line is: ax+by+c= 0

converting:

y= 1/3x- 7/3 ⇒ 3y= x- 7 ⇒ x- 3y - 7=0
