EXPLANATION
Let's see the facts:
The scale is---> 14 milimeters ----> 5 meters
Width = 42 milimeters
Applying the unitary method, the actual width of the pool is:
![Actual_{}width=42\text{ mm}\cdot\frac{5m}{14\text{ mm}}=15m](https://tex.z-dn.net/?f=Actual_%7B%7Dwidth%3D42%5Ctext%7B%20mm%7D%5Ccdot%5Cfrac%7B5m%7D%7B14%5Ctext%7B%20mm%7D%7D%3D15m)
The width of the pool is 15m
Answer:
5 degrees
Step-by-step explanation:
We are given that during a science experiment
The temperature of a solution in a beaker 15 degrees below zero
The temperature of solution in a beaker 2 was opposite of the temperature in beaker 1
We have to determine the temperature of beaker 2.
It mean temperature of beaker 1 solution=-5 degrees
According to question
Temperature of beaker 2 solution =5 degrees
Hence, the temperature of solution in a beaker 2=5 degrees
Answer:
n= 21 option B
Step-by-step explanation:
a1= 30, d = -4, and Sn = -210
WE use sum formula
we are given with a1 and d so its arithmetic sequence
the sum formula for arithmetic sequence is
![S_n = \frac{n}{2}(2a_1 +(n-1)d)](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cfrac%7Bn%7D%7B2%7D%282a_1%20%2B%28n-1%29d%29)
a1= 30 and d= -4 sn =-210
Plug in the values and solve for n
![-210= \frac{n}{2}(2(30) +(n-1)(-4))](https://tex.z-dn.net/?f=-210%3D%20%5Cfrac%7Bn%7D%7B2%7D%282%2830%29%20%2B%28n-1%29%28-4%29%29)
![-210= \frac{n}{2}(60-4n+4)](https://tex.z-dn.net/?f=-210%3D%20%5Cfrac%7Bn%7D%7B2%7D%2860-4n%2B4%29)
![-210= \frac{n}{2}(64-4n)](https://tex.z-dn.net/?f=-210%3D%20%5Cfrac%7Bn%7D%7B2%7D%2864-4n%29)
Now distribute the fraction n/2
-210 = 32n - 2n^2
we add 210 on both sides
-2n^2 +32n +210=0
Divide whole equation by -2
![n^2 - 16n - 105=0](https://tex.z-dn.net/?f=n%5E2%20-%2016n%20-%20105%3D0)
Now we factor left hand side
Product is -105 and sum is -16
-21 times (5) = -105
-21 + (5) = -16
(n-21) (n+5)=0
n -21 = 0 so n= 21
n +5 =0 so n = -5
number of terms cannot be negative so n= 21
Answer:
Step-by-step explanation:
Numer 1: The answer to this problem is 4 pounds
Numer 2: 13 cups
Explanation:
Four jars of sauce with 26 oz would be a total of 104 ounces
4 x 26 = 104
1 cup contains 8 ounces.
104 oz x
=13 cups
Numer 3: Since, 1 quartz = 33.307 ounces ( approx )
⇒ 3 quartz = 99.921 ounces
If the total number of players = 16,
And, the given fluid is divided equally among these players,
Then the total quantity of fluid each player get
![\frac{toral quality od drink }{ total players}](https://tex.z-dn.net/?f=%5Cfrac%7Btoral%20quality%20od%20drink%20%7D%7B%20total%20players%7D)
=![\frac{99.921}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B99.921%7D%7B16%7D)
=6.24505625= 6.245
Hence, each player will get around 6.245 ounces of the drink.
Number 4:
36 inches or 3 feet is the correct answer
Number 5 ;
The correct answer for the question that is being presented above is this one: "10 pounds." An office supply company is shipping a case of wooden pencils to a store. There are 64 boxes of pencils in the case. If each box of pencils weighs 2.5 ounces, then...
There are:
64 boxes of pencils
1 box weighs 2.5 ounces
Find its total weight in pounds.
1 ounce = 0.0625 pounds
64 boxes * 2.5 ounces = 160 ounces
160 ounces * 0.0625 pounds/1 oz = 10 pounds.
The 64 boxes of pencils weigh 10 pounds.
