Answer:

A,D,F

Step-by-step explanation:

if he drives 90 in 2 hours then in one hour its 45. 45 times 2 is 90. 45 times 3 is 135. 45 times 4 is 180. 45 times 5 is 225. 45 times 6 is 270. 45 times 7 is 315. and 45 times 8 is 360.

A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round to the nearest hundredt

Firlakuza [10]

Answer:

Step-by-step explanation:

Ok so the formula for a circle is

A=πr2

The diameter of the semicircle is 15, so if you divide that by 2 you will get a radius of 7.5. Then, the next part of the formula is to square the radius, and to do that you need to multiply the radius by itself. You will then get an answer of 56.25. And then finally, you multiply 56.25 by pi, which is 3.14 and get 176.625. Then for the quarter circle, you have 2 side lengths of 15 feet. To find the area of the quarter circle, do pi times the radius(15), and square the answer. Then, divide the answer by 4 to get the quotient, 554.6025. 176.25 + 554.6025 is 730.8525 . That rounded to the nearest 100th is 730.85.

I really hope this helped and I'm sorry if it is incorrect.

Answer:

$x>\frac{1}{2} \\x$

Step-by-step explanation:

If we solve for 'x' variable, its recommended to multiply 'x' variable in both sides of inequality:

we have $\frac{1}{4}< x^{2} \\$

This is a quadratic equation, two answer are going to be obtained from here.

since $\sqrt{x^{2} } = |x|$

Applying square roots to both sides of inequality sign we wil have the following

$\sqrt{\frac{1}{4} } < \sqrt{x^{2} }$

This leaves to the following

$\frac{1}{4}$

remember that $|x|= +/ - x$

$x>\frac{1}{2} \\x$

Rewrite an equation so does not have fractions 5/6x+2=3/6

Dovator [93]

9514 1404 393

Answer:

5x +12 = 3

Step-by-step explanation:

Multiply both sides of the equation by the least common denominator. Here, that is 6.

$\dfrac{5}{6}x+2=\dfrac{3}{6}\qquad\text{given}\\\\6\left(\dfrac{5}{6}x+2\right)=6\times\dfrac{3}{6}\qquad\text{multiply by 6}\\\\5x+6\times2=3\qquad\text{eliminate parentheses}\\\\\boxed{5x+12=3}}$
