Answer:
The first one yes
The second one yes they are congruent
The third one yes because when you divided 34 by 27.2(34/27.2) =1.25, 23 by 18.4 (23/18.4)=1.25 and 31 by 24.8(31/24.8)=1.25 so they are proportional.
Answer:
The answer is A
Step-by-step explanation:
When you look at the clock, you see a circle. A circle is 360 degrees. The clock shows the time of 6:00, and the hands are 180 degrees away from each other as they are exactly across from each other. Then, you divide 180, the degrees from each hand, to the total degrees of the circle to get 1/2.

Answer:
9 weeks
Step-by-step explanation:
In problems of this nature, the usual assumption is that the time required is proportional to the work product and inversely proportional to the number of people doing the job. Here, there is no change in the amount of work, but the number of people is reduced by a factor of 12/18 = 2/3.
So, the amount of time required is expected to increase by a factor of 1/(2/3) = 3/2.
(6 weeks)×(3/2) = 9 weeks
It would have taken 9 weeks to sew the 540 dresses.
If the charge on a single-use bag is 25 fils, then the notations that shows the amount of dirhams that the store will get after one year can be expressed as 0.25x.
Given that the charge on single-use bag is 25 fils.
We are required to give the express the amount of dirhams that the store will get after one year.
Equation is the relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be a linear equation,quadratic equation,cubic equation and many more depending on the powers of variables that are present in the equation.
let the number that single use bag used in 1 year be x.
We know that there are 100 files in a dirham, so 25 fils will be 0.25 dirham.
Equation that shows the number of dirham that the store will get after one year=0.25x.
Hence if the charge on a single-use bag is 25 fils, then the notation that shows the amount of dirham that store will get after one year can be expressed as 0.25x.
