When comparing decimals, start in the tenths place. The decimal with the biggest value there is greater. If they are the same, move to the hundredths place and compare these values. If the values are still the same keep moving to the right until you find one that is greater or until you find that they are equal.
Answer:
2
Step-by-step explanation:
Given in the question,
a + b = √17
(a+b)² = 17
a² + b² +2ab = 17
a² + b² = 17 - 2ab
<h3>Area of triangle </h3>
1/2 (h)(b)
here h is perpendicular height of triangle = a
b is the base of triangle = b
<h3>Use pythagorus theorem:</h3>
hypotenuse² = base² + height²
3² = a² + b²
9 = a² + b²
9 = 17 - 2ab
9 - 17 = -2ab
-8 = -2ab
cancel minus on both sides
8 = 2ab
ab = 8/2
ab = 4
Plug ab in the formula of area
1/2 (h)(b)
1/2 (a)(b)
1/2 (4)
4/2

Answer:
The measure of the third side is 
Step-by-step explanation:
we know that
Applying the law of cosines
where
C is the angle between side a and side b
we have
substitute
It's the bottom one. Miko found the incorrect and checked her work using multipication incorrectly.
This is because the correct way to solve this would to use (5/1) * (3/5) = (15/5) then simplify it to 3/1 or simply 3.
Dividing fractions is simply flipping the second fraction and then multiplying across
The given function is
f(x) = 4x - 3/2
where
f(x) = number of assignments completed
x = number of weeks required to complete the assignments
We want to find f⁻¹ (30) as an estimate of the number of weeks required to complete 30 assignments.
The procedure is as follows:
1. Set y = f(x)
y = 4x - 3/2
2. Exchange x and y
x = 4y - 3/2
3. Solve for y
4y = x + 3/2
y = (x +3/2)/4
4. Set y equal to f⁻¹ (x)
f⁻¹ (x) = (x + 3/2)/4
5. Find f⁻¹ (30)
f⁻¹ (30) = (30 + 3/2)/4 = 63/8 = 8 (approxmately)
Answer:
Pedro needs about 8 weeks to complete 30 assignments.
