0.20*x = 0.01*x + 38 => 0.19*x = 38 =>( 19/100 )*x = 38 => x = 3800/19 => x = 200.

Mrs. Chen owns two pieces of property. The areas of the properties are 77,120 square feet and 33,500 square feet. 43,560= 1 acre
Find the total number of acres Mrs. Chen owns, to the nearest hundredth of an acre and please explain how to do it.

Answers

First add the two areas of the properties together.
77120 + 33500 = 412120 square feet
Divide this number by 43560 to get the number of acres.
412120/43560 = 9.46

Answer: 9.46 acres

Okay so there are two pieces of property Mrs. Chen owns, so in order to find the total number of feet, add 77,120 and 33,500.
77,120 + 33,500= 110,620
1 acre= 43,560
To find the total number of acres now, you divide 110,620 ÷ 43,560
and that equals about 2.54. (Since you asked for the nearest hundredth of an acre)

What is the sum of the quotients of 25x^2/5x and the quotient of 8x^2/x

Answers

If you would like to solve (25 * x^2) / (5 * x) + (8 * x^2) / x, you can calculate this using the following steps:

(25 * x^2) / (5 * x) + (8 * x^2) / x = 5 * x + 8 * x = 13 * x

The correct result would be 13 * x.

Find the next two terms of the sequence: 80, ?40, 20, ?10, ______, ______. A) 20, 40 B) 1 2 , 1 4 C) 5, ? 5 2 D) ?30, ?40

Answers

Answer:

The correct option is C) 5, 5/2

The sequence given is:

80, 40, 20, 10, _____, ______

If we look at the given numbers, it appears that every next number is obtained by dividing the previous number of 2.

Like 40 is obtained by dividing 80 by 2

$(80)/(2)=40$

Similarly:

$(40)/(2)=20$

$(20)/(2)=10$

$(10)/(2) = 5$

$(5)/(2)$

Therefore, the complete sequence is:

80, 40, 20, 10, 5, 5/2

Hence the correct option is C) 5, 5/2

Answer:c

Step-by-step explanation:

At 10:57 A.M. A submarine was at a depth of feet. Its depth then changed at a rate of -8 feet per minute. What was its depth at 11:03 A.M.? Group of answer choices

Answers

Answer:

48 feet

Step-by-step explanation:

First we need to get the total minutes used by the submarine from 10:57 A.M to 11:03 A.M. The total minutes used within the specified period of time is 6 minutes.

If its depth then changed at a rate of 8 feet per minute, the submarine depth after 6 minutes will be expressed as shown;

8 feet = 1minute

x feet = 6 minutes

cross multiply;

x * 1 = 8 * 6

x = 48 feet

Hence the submarine depth at 11.03AM is 48 feet

74 3/5 + 19 2/3 = Please Explain

Answers

Ok 74 $(3)/(5)$
So 19 $(2)/(3)$

= 373/5 + 59/3

= ((373 × 3) + (59 × 5)) / (5 × 3)

= (1119 + 295) / 15

= 1414/15

= 1414/15

= 94 4/15

74 3/5 + 19 2/3
74+19= 93
for 3/5+2/3 we need a common denominator which in this case would be 15 (the product of the two already existing denominators)
3x3=9 (the 3s are first numerator and the second denominator) so the first fraction is 9/15
5x2=10 (the first denominator and the second numerator) so the second fraction would be 10/15
9+10=19 (the numerators in both fractions) so it's 19/15 which we convert to a mixed numeral which is 1 4/15
93+1 4/15=94 4/15

hope this helps :)
