Three manufacturers of plastic products a,b and c received an order to make 1950 plastic filters in the ratio 7:8:11.

leva [86]

7+8+11=26

So the first manufacturer makes 7/26 of all filters
the socond one makes    8/26 of all filters
and the third one makes 11/26 of all filters

A)
Number of plastic filters A:
   $A=\frac7{26}\cdot1950=7\cdot75=525$
Number of plastic filters C:
   $C=\frac{11}{26}\cdot1950=11\cdot75=825$

B)
Number of plastic filters B:
   $B=\frac8{26}\cdot1950=8\cdot75=600$
85cents = 0,85$ (or €?)
Amount of money B will receive:
   $600\cdot0,85=6\cdot85=510$
C)
The main thing that will change is the number of plastic filters to make:

1950-338=1612
So:
   Number of plastic filters A:
      $A=\frac7{26}\cdot1612=7\cdot62=434$
   Number of plastic filters B:
      $B=\frac8{26}\cdot1612=8\cdot62=496$
   Number of plastic filters C:
      $C=\frac{11}{26}\cdot1612=11\cdot62= 682$

If x=3 and y=7, evaluate the following expression: 100 − 3 ( 3 − 4x )

coldgirl [10]

Answer:

$100 - 3(3 - 4x) \\ = 100 - 3(3 - 4 \times 3) \\ = 100 -27 \\ = 73$

What is the equation of a line that passes through (-6, 2) and has a slope of −1/2 ?

natta225 [31]

Slope = -1/2
(-6, 2)

y - 2 = -1/2 (x + 6)
y - 2 = -1/2x - 3
y = -1/2x -1

answer is B

Write the quantity as percentage of the second (give answers to the nearest whole number).

GarryVolchara [31]

Answer:

Step-by-step explanation:

We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.

Both numbers in cents:

50/4000

OR, both numbers in dollars:

.50/40.00

Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.

50÷4000 (OR .5/40)

= 0.0125

times by 100

0.0125 × 100

= 1.25% but the directions said to round to the nearest whole number, that's 1%

Tell me the answer in slope intercept form

den301095 [7]

Answer:

y=-2x+4

Step-by-step explanation:

the y int is (0,4), so b in y=mx+b is 4

the slope is -2, so the m in y=mx+b is -2

so, y=-2x+4 is your equation
