Find the ratio between 450 ml and 1l.
Answer:
450mL : 1L = 9 : 20
Step-by-step explanation:
recall that 1L = 1000 mL,
450 mL : 1L can be expressed as
450mL : 1000 mL (we can simplify this with the following steps)
450 : 1000 (divide both sides by 10)
45 : 100 (divide both sides by 5)
9 : 20 (answer)
A clerical worker takes 2 times as long to finish a job as it does an executive secretary. Working together, it takes them 6 hr to finish the job. How long would it take the clerical worker, working alone, to finish the job?
Answer:
18 hoursStep-by-step explanation:
This problem is on Combined work rate
Step one:
given data
let the secretary take x hours to finish one job
so the clerical worker will take 2x hours to finish one job.
Both of them working together will take 6 hours
Step two:
The combined work formula is
T/A+T/B=1
Where T= time working together
A= time the Clerical worker spent alone
B= time the secretary spent alone
substituting we have
6/2x+6/x=1
solve for x
6+12/2x=1
18/2x=1
9/x=1
cross multiply
x=9 hours
the clerical worker take 2x hours
2*9= 18 hours
A vertical stick 12 m long casts a shadow 8 m long on the ground. At the same time a tower casts the shadow 40 m long on the ground. The height of the tower is : *
Answer:
60m tall
Step-by-step explanation:
Since this is a ratio problem and we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the height of the tower which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
12m height <======> 8m shadow
x height <======> 40m shadow
(40m * 12m) / 8m = 60m height
Finally, we can see that the height of the tower is 60m tall.

Answer:
So, solving the equation [tex]2 \frac{1}{3} \times 4\frac{1}{5}[/tex] we get [tex]9\frac{4}{5}[/tex]
Step-by-step explanation:
We need to solve the given equation: [tex]2 \frac{1}{3} \times 4\frac{1}{5}[/tex]
First converting mixed fractions into improper fractions
[tex]\frac{7}{3} \times \frac{21}{5}[/tex]
Since 21 is divisible by 3 so, simplifying and multiplying
[tex]=7 \times \frac{7}{5} \\=\frac{49}{5} \\=9\frac{4}{5}[/tex]
So, solving the equation [tex]2 \frac{1}{3} \times 4\frac{1}{5}[/tex] we get [tex]9\frac{4}{5}[/tex]

A dance team is going to spend $1,440 to purchase all sweatshirts or all jackets for the team members. Sweatshirts cost $24 each. Jackets cost $32 each. What is the greatest number of sweat- shirts or jackets the team can purchase?
Answer:
60 sweatshirt
Or
45 jackets
Step-by-step explanation:
Total amount = $1,440
Sweatshirts = $24
Jackets = $32
What is the greatest number of sweat- shirts or jackets the team can purchase?
The greatest number of sweat- shirts the team can purchase = Total amount / cost of sweatshirt
= $1,440 / $24
= 60
The greatest number of jackets the team can purchase =Total amount / cost of jackets
= $1,440 / $32
= 45
Therefore, the greatest number of sweat- shirts or jackets the team can purchase is
60 sweatshirt
Or
45 jackets
Answer:
45 or 60

Instructions: Solve the following literal equation.
Solve 3x+ 15y = 24 for x.
Step-by-step explanation:
3x+15y= 24
x+15y=24/3
x+y= 8/15
x= 8/15-y
The solution for x is x = 8-5y.
Given is an equation 3x + 15y = 24, we need to solve for x,
To solve the literal equation 3x + 15y = 24 for x, we need to isolate x on one side of the equation.
Let's begin by subtracting 15y from both sides of the equation:
3x + 15y - 15y = 24 - 15y
This simplifies to:
3x = 24 - 15y
Now, we can divide both sides of the equation by 3 to solve for x:
(3x)/3 = (24 - 15y)/3
Simplifying further:
x = (24 - 15y)/3
Take 3 as common factor,
x = 3(8-5y) / 3
x = 8-5y
Therefore, the solution for x is x = 8-5y.
