<u>Answer</u>


= 14.6 feet


<u>Explanation</u>

The length of the ladder is 15 feet and it is place against the wall 3.5 feet from the base of the wall.

This makes a right triangle with a base length of 3.5 feet and a hypotenuse of 15 feet.

So, we can use the pythagorean theorem to calculate the height required.

a² = c² - b²

Where a and b are the legs of the right triangle and c is the hypotenuse.

a² = c² - b²

h² = 15² - 3.5²

h² = 225 -12.25

= 212.75


h = √212.75

= 14.58595215

Mike and his dad are retiling his bathroom floor. They have budgeted $200 for the tiles and supplies. The tiles cost $1.85 each
Feliz [49]

Answer:

Equation: $114.90 + $1.85<em>x</em> = 200

Solution: They can buy 46 tiles.

Step-by-step explanation:

First, subtract 114.90 from both sides to get 1.85<em>x</em> = 85.10.

Divide 85.10 by 1.85 to get 46, which is the answer.

Can anyone simplify 24q2/8q-3
Morgarella [4.7K]
24q^2 / 8q^-3

lets break this down...
24/8 = 3

q^2 / q^-3....when dividing exponents with the same base, keep the base and subtract the exponents. q^2 / q^-3 = q^(2 -(-3) = q^(2 + 3) = q^5

put them together and u get : 3q^5

What is the mean of the data set?
andre [41]
You find the mean by adding each value then dividing the sum by the number of values there were so in this case you'd say 301 + 222 + 287 + 310 + 346 which is 1466 then divide by 5 because there are 5 values and your answer is 293.2!

I hope this helps

Find two positive consecutive integers such that the square of the first added to three times the second is 24
Naddika [18.5K]

Answer:

3 and 5

Step-by-step explanation:

Let the two consecutive odd integers be x and x + 2.

Now,

The given statement is

x^2 + 3 \times (x+2)=24\\x^2 + 3x+6-24 = 0 \\x^2 + 3x-18 = 0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x=3,-6

Taking x=3.

Hence, two consecutive odd integers are 3 and 5.
