Why is 7/10 less than 4/5

Answers

Since both fractions mean to divide, I like to divide the numerators by the denominator, and I'll show you how I do it ----

7/10 = 0.7, or 70%

4/5 = 0.8, or 80%

You can now see that the 80% is larger than the 70%, and, this is why 7/10 is less than 4/5 :D
if you find the LCD of the two fractions, (10) and multiply the second one to be over tenths, it is 8/10. because 8/10 is more than 7/10, it is the greater of the two.

One angle of an isosceles trapezoid has measure 57. What are the measures of the other angles?

Answers

\alpha =57^o\n \n The \ interior \ angle \ at \ the \ shortest \ base \ is \ equal \ to :\n \n \beta = 180^o - 57^o = 123^o
In an isosceles trapezoid the two adj angles are equal
& the two opposite angles are equal & the
sum of the interior angles =360
so      57 + 57 = 114
360-114 = 246
the other angles are  246/2    = 123
the measure of the other angles are        57,123 & 123

"The sum of three numbers is 48. The second number is three times the first, while the third number is twice the first. Find the numbers What is the average of the numbers" 1. The three numbers are 8, 24, and 16. 2. The three numbers are 12, 36, and 24. 3. The three numbers are 10, 30, and 20. 4. The three numbers are 15, 45, and 30.

Answers

Answer: 1st choice : 8, 24, 16 and the average of the three numbers is 16

Step-by-step explanation:

let these 3 numbers be represented as x, y, z

x is the first, y is the 2nd, and z is the third.

x + y + z = 48

y = 3x

z = 2x

x + 3x + 2x = 48

6x = 48

x = 8

y = 3*8 = 24

z = 2*8 = 16

Average = (x+y+z)/3 = 48/3 = 16


From MysticAlanCheng

Anna invests $875 into an account and receives 4% simple interest for 24 months. How much simple interest will she earn??

Answers

Answer:

$70

Step-by-step explanation:

1. I = PRT

2. Sub in what you know into the equation:

I = $875 (principal amount) x 0.04 (4%) x 2 (24 months = 2 years)

3. 875 x 0.04 x 2 = 70

4. Anna will receive $70 in simple interest

Answer:

£70

Step-by-step explanation:

simple interest (I) is calculated as

I = (PRT)/(100)

where P is principal, R is rate of interest and T is time in years.

Note that 24 months = 2 years, thus

I = (875(4)(2))/(100) = (7000)/(100) = £70
