One city's highest temperature during this passed summer was 34 degrees Celsius, a second city's highest temperature over

PtichkaEL [24]

Answer:

$\°F = 93.2$

City 2 has a higher temperature

Step-by-step explanation:

Given

$\°F = (\°C * 9/5) + 32$

$City\ 2 = 97\°F$

Required

Convert 34°C to °F

Substitute 34 for C in the above formula:

$\°F = (34 * 9/5) + 32$

$\°F = 61.2 + 32$

$\°F = 93.2$

Comparing 93.2 to City 2's temperature of 97; we can conclude that city 2 has a higher temperature

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

Alchen [17]

We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.

The value of x is 5 feet.
