An angelfish was 1 1/2 inches long when it was bought. Now it is 2 1/3 inches long.a. How much has the angelfish grown?

b. An inch is 1/12 of a foot. How much has the angelfish grown in feet?

40 points!

Answers

Earlier, The length of the angelfish = $1 (1)/(2)$ inches

Now, the length of angelfish = $2 (1)/(3)$ inches

We have to determine the grown length of angelfish

= $2 (1)/(3)$ - $1 (1)/(2)$

= $(7)/(3)- (3)/(2)$

LCM of '2' and '3' is '6',

= $(14-9)/(6)$

= $(5)/(6)$ inch

Therefore, the angelfish has grown by $(5)/(6)$ inch.

We have to determine the increased length of angelfish in feet.

Since $1 inch = (1)/(12)$ foot

So, $(5)/(6) inch = (5)/(6) * (1)/(12) = (5)/(72)$

= 0.069 foot.

The answer for A is 5/6 inches.
2 1/3 - 1 1/2 = 2 2/6 - 1 3/6

= 2 + 6 / 6 - 1 3/6 = 8/6 - 1 3/6 = 5/6

The answer for B is 0.0694 feet.

Question part points submissions used two cars start moving from the same point. one travels south at 32 mi/h and the other travels west at 24 mi/h. at what rate is the distance between the cars increasing three hours later? mi/h

Answers

Since the cars start at the same point and are going in directions at right angles to each other, the speed at which the distance between them is increasing is a constant that can be computed as the Pythagorean sum:

... d = √(32² + 24²) = 40 . . . . mi/h

The sum of the angle measures of any trapezoid is greater than the sum of the angle measures of any parallelogram.

Answers

Answer:

False. Trapezoids and parallelograms are both types of quadrilaterals. 4 sided figures. The sum of a quadrilateral's angles is always equal to 360. The sum of a trapezoid's angles, as well as the sum of a parallelogram's angles, will always be equal. I hope this answers your question.

2) Mr. Riley dove off a cliff that was 30 feet above the surface of the water and descended a total of 100 feet. Which of the equations below can be used to determine his elevation at the bottom of his dive?a) 30 + 100
b) 30-100
C) 30 + (-100)
d) Both b and c

Answers

Answer:

Step-by-step explanation:

Mr.Riley was 30 feet above the water, which means he is at +30 above sea level. If he descends 100 feet, that means he goes 100 feet lower then that. 30 - 100 is equal to -70. He is 70 feet under water after he dived. You do not need to know the answer, but it helps to visualize the problem you have, therefore, finding the answer

Step-by-step explanation:

b = a^2/4 +4

Let a =8

b = 8^2 /4 +4

= 64/4 +4

= 16 +4

= 20

Answer:

b = 20 when a = 8.

Step-by-step explanation:

For this problem, we will simply plug the value of a=8 into the given equation for b, to find the value of b.

b = [ (a)^2 / 4 ] + 4

b = [ (8)^2 / 4 ] + 4

b = [ 64 / 4 ] + 4

b = [ 16 ] + 4

b = 20

Hence, when the value of a=8, then the value of b=20.

Cheers.
