A screen door spring has a spring constant of 188 N/m, and stretches 0.292 m when the door is opened. What force does it exert?
(Unit = N)
Answers
Answer:
The answer is 54.896N
Step-by-step explanation:
From Hooke's law,
Force = spring constant x extension
i.e
F = k x e
F = 188N/m x 0.292m
F = 54.896N
Answer:
54.846N
Step-by-step explanation:
Force = ?
Spring constant (K) = 188N/m
Spring stretch (x) = 0.292m
Force acting on a spring = spring constant * spring stretch
Force = 188 * 0.292
Force = 54.896N
The force acting on the spring is 54.896N

A patient takes vitamin pills. Each day he must have at least 420 IU of vitamin A, 5 mg of vitamin
B1, and 60 mg of vitamin C. He can choose between pill 1, which contains 120 IU of vitamin A, 1
mg of vitamin B1, and 10 mg of vitamin C, and pill 2, which contains 60 IU of vitamin A, 1 mg of
vitamin B7, and 15 mg of vitamin C. Pill 1 costs 30¢, and pill 2 costs 60¢. Complete parts a and b
below.
Answers
Final Answer:
Pill 1 is more cost-effective, meeting or exceeding daily requirements for vitamins A, B1, and C with lower cost (30¢) compared to pill 2 (60¢). It provides 480 IU of vitamin A, 5 mg of vitamin B1, and 60 mg of vitamin C with fewer pills, making it the optimal choice.
Step-by-step explanation:
The patient's daily requirements are 420 IU of vitamin A, 5 mg of vitamin B1, and 60 mg of vitamin C. Let's evaluate the contribution of each pill to these requirements.
Pill 1 provides 120 IU of vitamin A, 1 mg of vitamin B1, and 10 mg of vitamin C.
Pill 2 provides 60 IU of vitamin A, 1 mg of vitamin B7, and 15 mg of vitamin C.
To meet the vitamin A requirement, the patient can take 4 pills of type 1 (4 * 120 IU = 480 IU), while it would take 7 pills of type 2 (7 * 60 IU = 420 IU). So, pill 1 is more efficient for meeting the vitamin A requirement.
For vitamin B1, both pills contribute 1 mg each, and since the requirement is 5 mg, the patient needs to take 5 pills of either type.
For vitamin C, the patient needs 60 mg. Pill 1 provides 10 mg per pill, so 6 pills are needed (6 * 10 mg = 60 mg). Pill 2 provides 15 mg per pill, so 4 pills are needed (4 * 15 mg = 60 mg).
Considering the cost, pill 1 costs 30¢, and pill 2 costs 60¢. Since both pills are equally effective in meeting the B1 requirement and pill 1 is more efficient for vitamin A and equally efficient for vitamin C, the patient should choose pill 1 due to its lower cost.

Answers
Answer:

Step-by-step explanation:
Omar1. $80 off
$1000 - $80 = $9202. 15% off
$920- 15% = $920 * 0.85 = $782Omar paid for repair: $782
Caleb1. 15% off
$1000 - 15% = $1000*0.85 = $8502. $80 off
$850 - $80 = $770Caleb paid for repair: $770
As per above:
$782 - 770 = $12Caleb paid $12 less than Omar for his car repair.
Final answer:
Omar and Caleb had car repairs costing $1,000. By utilizing coupons differently, Caleb paid $12 less than Omar for the repair.
Explanation:
Omar and Caleb each had a repair made on their cars costing $1,000 initially. Omar used the $80 coupon first and then the 15% coupon. Caleb used the 15% coupon first and then the $80 coupon.
Omar: $1,000 - $80 = $920 remaining, then 15% off: $920 - 0.15*$920 = $782
Caleb: $1,000 - 0.15*$1,000 = $850 remaining, then $80 off: $850 - $80 = $770
Caleb paid less by $12 compared to Omar for his car repair.

b .y=8x-5
c. y=-5x+8
d. y=-5x-8
Answers
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = - 5, thus
y = 8x - 5 → B
Answer:
B
Step-by-step explanation:
y = mx + b
m represents slope and b is the y intercept
so 8x is mx in this equation and -5 is b

If the mean of the data set is 35 apples find the number of apples on the Granny Smith tree
Answers
35apples:
The number of apples on the Granny Smith tree can be found by looking at the mean of the data set, which in this case is 35 apples.
To determine the number of apples on the Granny Smith tree, just consider that the mean represents the average value of the data set.
Since the mean is 35, then you can conclude that there are 35 apples on the Granny Smith tree.
The number of apples in the Granny Smith tree is 41.
To find the number of apples in the Granny Smith tree, we can use the fact that the mean (average) of the data set is 35 apples. The mean is calculated by summing up all the values and dividing by the total number of values.
Let x be the number of apples in the Granny Smith tree.
The mean of the data set can be calculated as:
[tex]\[ \text{Mean} = \frac{\text{Sum of all values}}{\text{Number of values}} \]For the given data set, the sum of all values is \( 34 + 29 + 36 + x \), and there are 4 values in total.[/tex]
So, we have the equation:
[tex]\[ 35 = \frac{34 + 29 + 36 + x}{4} \]Now, let's solve for \( x \):\[ 35 \times 4 = 34 + 29 + 36 + x \]\[ 140 = 99 + x \]\[ x = 140 - 99 \]\[ x = 41 \][/tex]
Therefore, the number of apples in the Granny Smith tree is 41.

Find the median, lower quartile, and upper quartile for the set of data. 4, 1, 11, 8, 2, 9, 7, 6, 10, 5 Median = Lower quartile = Upper quartile =
Answers
Answer:
the answer is 6.5, 4, and 9.
Step-by-step explanation:
The median is 6.5.
The lower quartile is 4.
The upper quartile is 9.
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
To find the median, we need to first put the data in order:
1, 2, 4, 5, 6, 7, 8, 9, 10, 11
There are 10 numbers in the data set, so the median is the average of the two middle numbers:
Median = (6 + 7)/2 = 6.5
To find the lower quartile, we need to find the median of the lower half of the data set: 1, 2, 4, 5, 6
There are 5 numbers in the lower half, so the median is the middle number:
Lower quartile = 4
To find the upper quartile, we need to find the median of the upper half of the data set: 7, 8, 9, 10, 11
There are 5 numbers in the upper half, so the median is the middle number:
Upper quartile = 9
Thus,
The median, lower quartile, and upper quartile are 6.5, 4, and 9.
