160 grams of rice is four times larger than the given 40 g.
So the number of Calories must be 4 times larger too. 

48 x 4 = 192 Calories in 160 g of rice

2. Craig read 3 books each week for 3 weeks. Joe read 4 books a week for 3 weeks. How many more books did Joe read? Choose the a

Burka [1]

Answer:

4*3 - 3*3;

Joe read 3 more books than Craig

Step-by-step explanation:

Given

Craig:

3 books weekly for 3 weeks

Joe:

4 books weekly for 4 weeks

Required

How many more books did Joe read.

First, we need to determine number of books Craig reads

If in a week, Craig reads 3 books

Then in 3 weeks, Craig reads 3 * 3 books

Next, we need to determine number of books Joe reads

If in a week, Joe reads 3 books

Then in 4 weeks, Joe reads 4 * 3 books

Next, we determine the difference;

$Difference = 4 * 3 - 3 * 3$

$Difference = 12 - 9$

$Difference = 3$

Hence, Joe reads 3 more books

Option D answers the question.

Please help questions 12,14,16

notka56 [123]

Answer:

12) y=3x-15

14) y=-1/2x

16) y=13x-105

Step-by-step explanation:

Parallel lines always have the same slopes but different y-intercepts. So, we can make the equation (b is y-intercept of new equation):

12) y=3x+b

14) y=-1/2x+b

16) y=13x+b

now, we can plug in each of the coordinates given to these equations.

12) (4,-3): 4 is x, -3 is y.

-3=3(4)+b

simplify: b= -15

14) (-4,2): -4 is x, 2 is y

2=-1/2(-4)+b

simplify: b=0

16) (9,12): 9 is x, 12 is y

12=13(9)+b

simplify: b=-105

Now, plug in those numbers to your equation for b value.

12) y=3x-15

14) y=-1/2x

16) y=13x-105

*for 14 we don't need to write anything after -1/2x because b=0*

F(x)= |3x-4|+2, find f(-10)

Zarrin [17]

$f(x)=|3x-4|+2 \\ \\
f(-10)=|3 \times (-10) -4|+2=|-30-4|+2=|-34|+2=34+2 \\ f(-10)=36$
