What is the difference between 1/4 and 2/3

2. At 1 pm, you leave Ellensburg at a constant speed of 75 miles per hour. At 2:30 pm, your

MA_775_DIABLO [31]

Here, we are required to determine how many hours your friend will drive in order to catch you.

(a) Your friend will have to drive 7 and a half hours inorder to catch you.

(b) You both will be 675 miles away from Ellensburg at that time.

If you leave at 1 pm; At 2:30pm;

That is; 1 and a half hours after leaving; you must have covered a distance, d = 75 × 1.5
d = 112.5miles.

Therefore, your position; S after 2:30pm is given by;

S(a) = 75t + 112.5 miles from Ellensburg.

For your friend; travelling at 90miles/hr;

His position is given as; S(b) = 90 × t

(a) For your friend to catch you, you both must be in the same position;

i.e S(a) = S(b)

75t + 112.5 = 90t

90t -75t = 112.5

t = 112.5/15

t = 7.5hours

(b) To determine how far you both are from Ellensburg; we can either evaluate:

S(b) = 90t or S(a) = 75t + 112.5

Therefore, By evaluating S(b) = 90t.

S(b) = 90 × 7.5

S(b) = 675miles from Ellensburg.

If triangle MAS ≅ triangle TAR. Which of the statements could be false? A) segment MA ≅ segment TA Eliminate B) segment MA ≅ seg

BabaBlast [244]

If triangle MAS ≅ triangle TAR, the statement that could be false is letter B) segment MA ≅ segment SA.

This can be false because these two congruent triangles can be 2 scalene triangles. So, segment MA can never be equal to segment SA. This can be true though, if and only if these triangles are isosceles triangles where 2 sides are equal. (See attached file to fully understand).

Tom caught 4 fish and his son caught 12 fish. The number of fish that Tom’s caught was what percent of the number of fish his so

Fofino [41]

Answer:

33.3 % (Approx) percent of fish that Tom’s caught of the number of fish his son caught .

25% is the percent of the total amount Tom caught.

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ values}$

Part First

As given

Tom caught 4 fish and his son caught 12 fish.

Here

Part value = 4

Total value = 12

Put in the formula

$Percentage = \frac{4\times 100}{12}$

$Percentage = \frac{400}{12}$

Percentage = 33.3 % (Approx)

Therefore the 33.3 % (Approx) percent of fish that Tom’s caught of the number of fish his son caught .

Second Part

As given

Tom caught 4 fish and his son caught 12 fish.

Total number of fish caught = 4 + 12

= 16

Part value = 4

Total value = 16

Put in the formula

$Percentage = \frac{4\times 100}{16}$

$Percentage = \frac{400}{16}$

Percentage = 25%

Therefore the 25% is the percent of the total amount Tom caught.

(a) The perimeter of a rectangular parking lot is 332 m.

Minchanka [31]

The answer should be 91 because for your total perimeter you add all the sides. So you already have your length of 75 which counts as 2 sides and equals up to 150. after you subtract your two sides from your perimeter you get 182. you then divide 182 by 2 to get your two remaining sides which gives you 91.
