False. The chord can be from any two points on the circle. The diameter is straight down the middle. So, the chord can be higher than the diameter.

True. A chord is a line segment that joins two points on any curve. 
Hope this helps!

5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out
julia-pushkina [17]

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

5\frac{1}{3}+x=2\frac{1}{2}

=\frac{16}{3} +x=\frac{5}{2}

Subtracting both sides from 16/3 we get:

x=\frac{5}{2}- \frac{16}{3}

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

x=\frac{5\times 3-16\times 2}{6}

x=\frac{15-32}{6}

x=\frac{-17}{6}

Therefore, the answer is x = -17/6.

How do you recognize if a binomial is a difference of perfect squares?
Sedbober [7]
First off, perfect squares are numbers that have factors that can be multiplied by two of the same numbers. (such as: 1,4,9,16,25,36,49,64,81, & 100). a perfect squares can also be when in is a number such as x^2 or x∧4 (as long as the exponents are multiples of two.) You might know that a binomial is two terms. So you can recognize it by those numbers I mentioned earlier being subtracted.

Hope you understood and I wasnt confusing =)

Answer:

298-275 = 23 cm thus D) is the answer

Step-by-step explanation:

First Box:

length l = 9.5 cm

width w = 5 cm

height h = 7 cm

diagonal d = 12.8160056 cm

total surface area S_tot = 298 cm2

lateral surface area S_lat = 203 cm2

top surface area S_top = 47.5 cm²

bottom surface area S_bot = 47.5 cm²

volume V = 332.5 cm³

Second Box:

length l = 7.5 cm

width w = 5 cm

height h = 8 cm

diagonal d = 12.0519708 cm

total surface area S_tot = 275 cm²

lateral surface area S_lat = 200 cm²

top surface area S_top = 37.5 cm²

bottom surface area S_bot = 37.5 cm²

volume V = 300 cm³
