i have 9/10 of a yard of fabric. it takes 2/7 of a yard to make a pillow how many pillows can i make and how much fabric is left
kumpel [21]

First I always gather the known information..


So we know you have 9/10 yards of fabric... and that you need 2/7 to make 1 pillow.


The way we can figure out how many you can make is by dividing 9/10 by 2/7....


3.15 is your answer but of course we cannot make 3.15 pillows so your answer should be rounded to 3 :)

You can make 3 pillows out of 9/10 yd of fabric


hope this helped ya

if there are 1050 students in a school and the ratio of boys to girls is 9:5 what is the number if boys in the school?​
katrin2010 [14]

Answer:

675

Step-by-step explanation:

Let the ratio be 'R'

Total number of students = 1050

Then,

9R + 5R = 1050

R = 1050

=> R = 75

Hence, the number of boys = 9R = 9 x 75 = 675

(0, -2) Correct or not?
8090 [49]
Make f(x) = y
f(x)= -1/8 (4) ^x+3 +6
y = -1/8 (4) ^x+3 +6
y-intercept is when the function crosses the y-axis, and the y-axis is always where x = 0
y = -1/8 (4) ^x+3 +6
y = -1/8 ( {4}^{0})+9 \\  {(anything)}^{0}  = 1 \\ y = -1/8 (1)+9 = 9 - (1 \div 8)  \\ = 8 \: (7 \div 8)
or was the equation instead:
y = -1/8 ( {4}^{(x + 3)})+6
???????
Because in that case it's totally different, so here goes...
y = -1/8 ( {4}^{(x + 3)})+6 \\ y = -1/8 ( {4}^{(0 + 3)})+6 \\ y = -1/8 ( {4}^{3})+6 \\ y = -1/8 (64)+6
y = -1/1 (8)+6 =  - 8 + 6 =  - 2
Therefore, yes it is correct that the y-intercept lies at the point (0, -2)
