The time t required to do a job varies inversely as the number of people working. It takes 5 hr for 3 cooks to prepare the food for a wedding rehearsal dinner. How long will it take 8 cooks to prepare the dinner?
Answer: It will take 1.875 hours
Step-by-step explanation:
Given that time t required to do a job varies inversely as the number of people working.
we have it expressed as
t∝1/N
where t is time required to do a job
N is the number of people working.
Introducing our constant of proportionality, we have tht
t=k1/N
t=k/N
Now since it takes 5 hr for 3 cooks to prepare the food , K becomes
t=k/N
5=K/3
K=5X3=15
Given that there are 8 cooks, time required to prepare dinner will be
t=k/N
t=15/8
t=1.875 hours
log subscript-4 (m^2)=log subscript-4 (18-7m)?
Answer:
m = {-9, 2}Step-by-step explanation:
log₄ (m²) = log₄ (18 - 7m)18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7
m² = 18 - 7mm² + 7m - 18 = 0m² + 2*3.5m + 12.25 = 30.25(m + 3.5)² = 5.5²m = - 3.5 ± 5.5m = 2 m = -9Answer:
[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]
Step-by-step explanation:
we are given a logarithm equation
[tex] \displaystyle \log_{4}( {m}^{2} ) = \log_{4}(18 - 7m) [/tex]
notice that, we have [tex]\log_4[/tex] both sides therefore we can get rid of it
[tex] \displaystyle {m}^{2} = 18 - 7m[/tex]
in order to solve it we should make it standard form we know that
[tex] \displaystyle a {x}^{2} + bx + c = 0[/tex]
so right hand side expression to left hand side and change its sign:
[tex] \displaystyle {m}^{2} + 7m- 18=0[/tex]
now we can solve it by using factoring method
to do so rewrite the middle term as sum or subtraction of two different terms
in that case -2m+9m is good to use
[tex] \displaystyle {m}^{2} - 2m + 9m - 18 = 0[/tex]
factor out m:
[tex] \displaystyle m({m}^{} - 2 )+ 9m - 18 = 0[/tex]
factor out 9:
[tex] \displaystyle m({m}^{} - 2 )+ 9(m - 2)= 0[/tex]
group:
[tex] \displaystyle (m - 2)(m + 9) = 0[/tex]
hence,
[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]
remember that,
when we deal with logarithm equation we should always check the roots
let's check the root 1:
[tex] \displaystyle \log_{4}( {2}^{2} ) \stackrel{?}{=} \log_{4}(18 - 7.2) [/tex]
simplify square:
[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(18 - 7.2) [/tex]
simplify multiplication:
[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(18 - 14) [/tex]
simplify substraction:
[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(4) [/tex]
simplify logarithm:
[tex] \displaystyle 1 \stackrel{ \checkmark}{=} 1[/tex]
let's check root 2:
[tex] \displaystyle \rm \log_{4}( { - 9}^{2} ) \stackrel{?}{=} \log_{4}(18 - 7.( - 9)) [/tex]
simplify square:
[tex] \displaystyle \rm \log_{4}( 81 ) \stackrel{?}{=} \log_{4}(18 + 63) [/tex]
simplify addition:
[tex] \displaystyle \rm \log_{4}( 81 ) \stackrel{ \checkmark}{=} \log_{4}(81) [/tex]
therefore,
[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]
i’ve been trying on this question but in struggling. please help me
Answer:
[tex]x \geq 15[/tex]
Step-by-step explanation:
Solving an inequality is very similar to solving an equation, one uses inverse operations. The only major difference between the two is that when one multiplies or divides an inequality by a negative number, one must remember to flip the inequality sign to ensure that the inequality remains true. In this situation, such a rule does not come into play.
[tex]\frac{x}{5} - 8 \geq -5[/tex]
Inverse operations,
[tex]\frac{x}{5}-8 \geq -5\\ +8\\\\\frac{x}{5} \geq 3\\*5\\\\x \geq 15[/tex]

Several students were asked how many blocks they walk from home to school each day results are shown in the line plot below Miguel walks the shortest distance jila Watch the longest distance how much farther Then Miguel does jila walk?
Answer:
Miguel walks 4.25 blocks more than Jila.
Step-by-step explanation:
Line plot shown in the question represents the distance traveled by the students from their houses to their school.
From the line plot,
Distance between 1 and 2 = [tex]\frac{1}{4}[/tex] = 0.25 blocks
Shortest distance traveled by Miguel = 0.25 blocks
Longest distance traveled by Jila = 4.5 blocks
Difference between the distances covered by Miguel and Jila = 4.5 - 0.25
= 4.25 blocks
Therefore, Miguel walks 4.25 blocks more than Jila.

A cylindrical waste can has a volume of 197.92 cubic inches and its base has a radius of 3 inches. Which measurement is closest to the height of the waste can
Answer:
7inches
Step-by-step explanation:
Volume of a cylinder = πr²h
r is the radius of the cylinder
h is the height of the cylinder
Given
r = 3inches
Volume = 197.92 cubic inches
Substitute
197.92 = 3.14(3)²*h
197.92 = 28.26h
28.26h = 197.92
h = 197.92/28.26
h = 7.003in
Hence the measurement that is closest to the height of the waste can is 7inches

How many different 2-digit ID numbers can be made if each ID number can use the numbers 1 through 8 and no digits may be repeated?
Answer:1,2,5,7,8 and 9. Thus, we have 6 numbers.
Step-by-step explanation:Then we want to form two-digit numbers without repetition. There are 6 number that is possible to occupy first digit, right? 1,2,5,7,8 or 9. Because it’s without repetition, so the number that have been filled the first digit cannot be the second digit. Thus, the numbers that possible to occupy second place are 5 digits.So step by step

Little Snail is going to visit his friend over at the next pond, 3 miles away. He can crawl ( 1/2. 1/3, 1/4, 3/4, 2/3 ) of a mile per day. How many days will it take him to get there
Solution :
It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.
When the snail crawls 1/2 of a mile per day, it will take him, [tex]$1 \times \frac{2}{1} \times 3$[/tex]
= 6 days to get to the next pond.
When the snail crawls 1/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{1} \times 3$[/tex]
= 9 days to get to the next pond.
When the snail crawls 1/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{1} \times 3$[/tex]
= 12 days to get to the next pond.
When the snail crawls 3/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{3} \times 3$[/tex]
= 4 days to get to the next pond.
When the snail crawls 2/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{2} \times 3$[/tex]
= 4.5 days to get to the next pond.
Find the distance between (-22,15) and (30, -25).
Answer:
65.60
Step-by-step explanation:
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(30−−22)2+(−25−15)2(30--22)2+(-25-15)2
= √522+(−40)2522+(-40)2
= √2704+16002704+1600
= √43044304 = 65.6049
