Answer:
There are 9 lemon bars left from the batch.
Step-by-step explanation:
One batch = 15 lemon bars
Josh: ate 2 lemon bars
13 lemon bars remaining.
Claire: ate twice as many as Josh
Meaning: 2 × 2 = 4
9 lemon bars remaining.
There are 9 lemon bars left from the batch.
Answer:
f(4) = 3
x = -1
Step-by-step explanation:
Line graphed shows a linear function.
Since this line passes through two points (4, 3) and (-1, 4)
Let the function is,
f(x) = mx + b
where 'm' = slope of the line
b = y-intercept of the line
Slope 'm' = 
= 
= 
f(x) = 
Since a point (4, 3) lies on the line,
f(4) = 
3 = 
b = 3 + 0.8
b = 3.8
Therefore, f(x) = -0.2x + 3.8
For x = 4
f(4) = -0.2(4) + 3.8
= -0.8 + 3.8
= 3.0
For f(x) = 4
4 = -0.2x + 3.8
0.2x = 3.8 - 4
x = 
x = -1
Answer:
$55.80
Step-by-step explanation:
First, find how much Janet saved by finding 1/5 of 15.50:
15.50/5
= 3.1
Find how much Rob saved by multiplying 3.1 by 12:
3.1(12)
= 37.2
Then, find the total saved amount by adding them all together:
15.50 + 3.1 + 37.2
= 55.8
So, they saved $55.80 in total
Answer: 1/8 has 1, 1/4 has 2, 3/8 has 3, 1/2 has 4, 5/8 has 2, and 3/4 has 3.
Step-by-step explanation:
You basically just count how many of them there are in the weight of potatoes box!
Answer:
174 rpm
Step-by-step explanation:
The question says that the speed is inversely proportional to the length. Thus, Inverse means, as the diameter increases, the speed reduces, or as the diameter reduces, the speed increases.
Thus, from the question, if diameter A is 20, and B is 10, then definitely, the speed will increase from 348 to a higher rate. Mathematically, we have
20 / 10 = 348 / x, where x is the missing speed.
2 = 348 / x
x = 348 / 2
x = 174 rpm
Therefore, the pulley A must have been running at a speed of 174 rpm
