Colby wants to set square tiles on the top of a wooden box. The top of the box is a rectangle 7 1/2 inches long and 5 1/2 inches wide.a. How many 1/2 inch tiles would Colby need to cover the top of the wooden box?
b. How many 1/4 inches tiles would Colby need to cover the top the wooden the box?

Answers

Answer 1
Answer: area of a rectangle is l x w 7.5 x 5 = 37.5 in^2 each tile is 1/2 or ,5 37.5/.5= 75 of the 1/2 in tile the 1/4 in tile would need twice as much therefore 150

James says tat 5/5 is greater than 9/10 is he correct Explain

Answers

okay so 5/5 is a whole so it equals 1 or 100% but 9/10 is 0.90 not a whole and is 90% Understand? lets say you had two tests. one test you got 5 out of 5 and got 100% and in another you had 10 questions and got 9 correct getting 90% the first test you had a higher score
yes, because 5/5 equals a whole wich is 1 5 times so its would be 5 but 9/10 is only 1.5 so james  is right

Which equation represents the linear relationship shown in the table? y=3x+4 y=3x+8 y=8x+3 y=4x+3 x y 0 3 2 11 4 19 6 27

Answers

Answer:

The linear relationship is given by,  y = 4x + 3

Step-by-step explanation:

The points given are ( as (x,y) pair)

x     y

0      3

2     11

4     19

6     27

The given lines are ,

1) y = 3x + 4

2) y = 3x + 8

3) y = 8x + 3

4) y = 4x + 3

Now , by inspection or trial and error method only line (4) does satisfy all the points, so the linear relationship is given by,

y = 4x + 3

Who do you do the problem 7/9+1/7+3/5? please explain thoroughly.

Answers

to add fractions you want to make sure that the bottom numbers are the same so we have to make them the same, but we have to make sure that the fractions are unchanged so we get the correct answer

so if we find out what number that 9,7, and 5 can all multiply into. we find that 9 times 7 times 5 or 315 is the number that will work

so to get them to all be over 315, we must multiply each fraction by a form of 1/1 or x/x or (number)/(same numbe as on top)

so 7/9 times (35/35)=245/315
1/7 times (45/45)=45/315
3/5 times (56/56)=168/315

we add them togther
245/315+45/315+168/315=(245+45+168)/315=458/315
this simplifies to 1 and 143/315

To add those fractions, you must find a common denominator for all of them. To find this, find a number that is a multiple of all three denominators.  Then, multiply the top of the fraction by the same number you multiplied to get the common denominator.  Finally you add all of the numerators together and keep the denomiator the same.

Example: 1/2+1/4+1/8

The demominators all are factors of the multiple 8.  Therefore, we will use 8.  Then, since we multiplied 2 by 4 to get eight for the first fraction, we will multiply the top number by 4 also. The new fraction will look like this: 4/8.  After you have done that to all of the fractions, the equation will look like this: 4/8+2/8+1/8.  Finally add all of the top numbers together and keep the denominator the same.  The answer would be 7/8

Hope this helped :)  Good luck

a painter has a 24-foot ladder that he is using to paint a house for safety reasons, the ladder must be placed at least 8 feet from the base of the side of the house. to the nearest tenth of a foot. How high can the ladder safely reach?

Answers

The ladder can safely reach up to 22.6 ft.

What is Pythagoras theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Given that, a ladder has a length of 24 ft, and it should be placed at least 8 feet from the base of the side of the house.

We need to find how high can the ladder safely reach,

Using the Pythagoras theorem here,

24²-8² = 576-64 = 512 ft

Hence, the ladder can safely reach up to 22.6 ft.

this is a pythagorean theorem problem. 24 is the whole ladder, and if you draw it out, is a hypotenuse. 8 is a leg. a^(2) + b^(2) = c^(2). so 8^2 + b^2 = 24^2

b^2 = 512, so b = sqrt(512) = 22.6
