Answer:
Last option is the correct choice.
Step-by-step explanation:
Convert the mixed numbers into fraction and apply the rate formula.
Rate = Change / Unit Time
= 12 1/4 ÷ 3 1/2
= 49/4 ÷ 7/2 (Answer matching with the last option)
= 49/4 x 2/7 (Inverting the second fraction)
= 7/2
= 3 1/2
The rate of change per hour is 3 and a half degrees in temperature.
Best Regards!
Answer:
D
Step-by-step explanation:
If you put a line down the middle of d and fold it in half it will be the same on both sides.
I answer would be B 100% - 13% = 87%
pulse tax 8% and you'll get B
Answer:
8.73 units
Step-by-step explanation:
Use the area formula, A = lw
Plug in the are and given side length, and solve for w
A = lw
24 = 2.75w
Divide each side by 2.75
8.73 = w
The other side length of the rectangle is approximately 8.73 units
The final step is to determine the principal square root of both sides of the equation.
- The triangle XYZ is a right triangle.
- The sides "a" and "b" are the height and the base of the triangle.
- The side "c" is the hypotenuse of the triangle.
- The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
- The side lengths must satisfy the Pythagorean theorem, a² + b² = c².
- It is also an isosceles triangle, so the equation becomes a² + a² = c².
- By combining like terms, we get 2a² = c².
- The final step is to take the square root of both sides.
- √2a = c
