Step-by-step explanation:

the numbers of the yellow and white counters

= 288- 38 = 250.

the ratio of yellow to white = 1:4

so,

the numbers of the yellow counters =

1/(1+4) × 250 =1/5 ×250 = 50

the numbers of the white counters =

4/(1+4) ×250 = 4/5 ×250 = 200

and the numbers of the red counters = 38

Question
marin [14]

Answer:

Step-by-step explanation:

From the table attached,

x-intercept of the linear function is, the value of 'x' when f(x) = 0  

x = 3 [x-intercept]

Function 'g' is the sum of 2 and the cube root of the sum of three time x and 1.

g(x) = 2+\sqrt[3]{3x+1}

For x-intercept,

g(x) = 0

2+\sqrt[3]{3x+1}=0

3x + 1 = (-2)³

3x + 1 = -8

3x = -8 - 1

3x = -9

x = -3

Therefore, the x-intercept of function 'f' is different or greater than the x-intercept of function g.

complete each statement with the appropriate measurement or symbol. 48 c = (fill blank) qt , 96 oz (fill blank) 5 lb , 6 yd, 1 f
DochEvi [55]

Answer:

48 cub = 12 Qt

96 Oz > 5 lb

6 yd 1 ft = 9 ft

6 1/2 lb = 104 oz

Step-by-step explanation:

Use the below key formula to convert the units.

1 cub = 4 Quart

16 ounce = 1 lb

96 ounce = 6 lb

1 yd = 3 feet

6 yd 1 ft = 6*3 + 1 = 18 + 1 = 19 feet

Hope this will help you to understand.

Thank you.
