Answer:
Square
Step-by-step explanation:
Given
[tex]\angle 1 = x + 60[/tex]
[tex]\angle 2 = 2x + 30[/tex]
1 and 2 are consecutive
Required
Determine a special name to the parallelogram
For consecutive angles 1 and 2 of a parallelogram, we have:
[tex]\angle 1 + \angle 2 = 180[/tex]
[tex]x + 60 + 2x + 30 = 180[/tex]
[tex]3x +90 = 180[/tex]
Collect like terms
[tex]3x = 180 - 90[/tex]
[tex]3x = 90[/tex]
[tex]x = 30[/tex]
Next, is to calculate angles 1 and 2
[tex]\angle 1 = x + 60[/tex]
[tex]\angle = 30 + 60 = 90[/tex]
[tex]\angle 2 = 2x + 30[/tex]
[tex]\angle 2= 2*30 + 30 = 90[/tex]
Both angles are 90.
This implies that each angle in the parallelogram is 90.
Such a parallelogram is either a rectangle or a square
Mrs.Diya and her mother-in-law are both school teachers and earn Rs.16,800 and Rs. 10,500 per month respectively. Ratio of distance to the school from their home, to the distance to the school from their colleague John’s home is 2 : 1.
1) If the distance to John’s home from the school is 12 km, what is the distance from school to Mrs. Deewan’s home?
2)If John’s earning twice the income of that of the mother in law, what is the ratio of their wages?
3)Who lives nearer to the school?
i need the correct answer and a proper answer with WORKING or else i will report
Answer:
1. the distance from the school to Mrs Deewan's home = 24km
2. John's wage to the mother-in-law's wage = 2:1
Mother-in-law's wage to John's = 1:2
3. John lives nearer the school
Step-by-step explanation:
1. The ratio of the distance between Mrs Diya's (Deewan's) home and John's home to school = 2:1.
This means that the distance of Mrs Diya's home is twice that of John's home to school. Therefore if John's home from school is 12km;
Mrs Diya's home = 12 × 2 = 24km
2. If john earns twice the income of the mother-in-law, the ratio of the wages is as follows:
John's wage to the mother-in-law's wage = 2:1
Mother-in-law's wage to John's = 1:2
3. John lives nearer the school. From the calculation we've done in 1 above, you can see that the distance between John's home and the school = 12km, while the distance between Mrs Diya's home and the school is 24km, therefore, John lives nearer the school.
In a cafeteria, 1 10 of the students are eating salads , and 2 5 are eating sandwiches. There are 20 students in the cafeteria. How many students are eating lunches other than salads or sandwiches?
Answer:Number of students eating lunches other than salads or sandwiches= 10
Step-by-step explanation:
Number of students in the cafeteria=20
Number of students eating salads=1/10 X 20= 2
Number of students eating sandwiches= 2/5 x 20 = 8
Number of students eating lunches other than salads or sandwiches=
Number of students in the cafeteria -(
Number of students eating salads +Number of students eating sandwiches)
=20-(2+8)
=20-10
=10 students.

After 10% tax, the phone cost $220. What was the original price?
Answer:
$198
Step-by-step explanation:
To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!
