If a thermometer indicates 40 degrees Celsius, what's the temperature in degrees Fahrenheit? A. 22°F B. 72°F C. 54°F D. 104°F

Elena L [17]

$F = 9/5C + 32$

F = 9/5(40) + 32
F = 72 + 32
F = 105

40°C is ~105°F, and the closest would be D.

Hajra's weekly pay this year is £676. This is 30% more than her weekly pay last year. Work out Hajra's weekly pay last year.

marissa [1.9K]

$\text{new pay}=\frac{130}{100}(\text{old pay})$ hence $\text{old pay}=\frac{130}{100}\cdot676=\boxed{\£520}$

36in rounded to the nearest tenth for circumference

WITCHER [35]

Answer: Remember that the tens place is two moves to the left of the decimal point (if it exists). To round to the nearest ten (nearest 10), we use the whole numbers place to determine whether the tens place rounds up or stays the same.

Solution steps:

Step 1: Locate and underline the tens place () and look to digit to the right (6):

Step 2: In this case, the digit to the right 6 is 5 or above. So, we add 1 to the tens place (). The digit(s) after the (6) are dropped. Thus, we get 40 as answer.

In short: 36 rounded to the nearest tens is 40.
