Adam can buy pencils in packages of 12 for $2.19, 40 for $3.99, 50 for $4.75, or 100 for $10. How many pencils are in the package with the lowest unit cost
Answer:
50 pencils
Step-by-step explanation:
2.19/12 = .18
3.99/40 = .09975
4.75/50 = .095
10/100 = .10
Although with mark-up to the hundredths place, there wouldn't be a logical difference is stores...
Answer:
50 for $4.75
Step-by-step explanation:
First step is to determine the unit cost of each pencil:
price of pack / number of units = cost per pencil
1. $2.19 / 12 = $0.1825
2. $3.99 / 40 = $0.09975
3. $4.75/ 50 = $0.095
4. $10 / 100 = $0.10
The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.

What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?
Answer:
[-1/2,1/20]
Step-by-step explanation:
Answer:
[-1/2,1/20]
Step-by-step explanation:
In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.
The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.
We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.
The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81
Responder:
4080,96 Julios
Explicación paso a paso:
La energía potencial gravitacional adquirida se puede obtener mediante la relación:
EPG = masa * aceleración por gravedad * altura
Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros
EPG = 52 * 9,81 * 8
EPG = 4080,96 julios

Plz explain If you do you will get brainlyes
Answer:
7-(-3)
Step-by-step explanation:
The answer is 7-(-3).
You're subtracting (-3) from 7.
7-(-3) = 7+3 because -(-3) = 3.
Compare | -3| And 1
PLS
Answer:
|-3| > 1
Step-by-step explanation:
Well |-3| = 3
3 > 1
1 < 3
(you can replace 3 for |-3| in those up there^)

A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.
Answer:
68.5 feet per minute
Step-by-step explanation:
rate of descent = feet / minute
First you need to find how many feet it has descended:
beginning altitude- ending altitude = total feet descended
5717 feet - 3388 feet = 2329 feet
To figure out the rate of decent we will divide
2329 feet / 34 minutes = 68.5 feet per minute
The hot air ballon descended 68.5 feet per minute for 34 minutes.

What is the value of x in the figure?
Answer:
x = 27
Step-by-step explanation:
The little square at the bottom of the figure means that that angle is a right angle, or 90°. Knowing that it's a 90° angle and that one section of the adjacent angle is 63°, we just calculate 90-63 to get 27, the value of x.

Someone help, I don't understand what trig ratio to use, or how to get the answer to w or x
Answer:
Uhm I think you need to like times the 10 to the 56? erm yeaaaaaaa SOrry if you get it wrong
Step-by-step explanation:
Answer:
1:2
Step-by-step explanation:
