3 feet = 1 yard. therefore 26 feet is equivalent to 6 yards with 2 feet left. The answer is 6 yards and 2 feet.
7 grams. 1,000 mg is equivalent to one gram.
Yes she will because 10 squared is 100 and when you multiply 20 by 6 it will equal 120 which means she will exceed her goal
The direct variation that of the speed to the skid length implies that the speed increases as the length increases
The car would be traveling at 59.96 mph
<h3>How to determine the speed of the skidding car?</h3>
A direct variation that illustrates the speed of the skidding car is:
s = k√l
Where:
- s represents the speed of the car
- l represents the length of the skid
- k represents the proportionality constant
Make k the subject in s = k√l
k = s /√l
Rewrite as:
s₁ /√l₁ = s₂ /√l₂
Substitute known values
40 /√178 = s₂ /√400
Evaluate the square root of 40
40 /√178 = s₂ /20
Multiply both sides by 20
800 /√178 = s₂
Evaluate the quotient
s₂ = 59.96
Hence, the car would be traveling at 59.96 mph

Given that,
ABC is a right angle triangle, C is the right angle.
To find,
cosB = ?
Solution,
The sum of angle of a triangle is equal to 180 degrees. So,
∠A + ∠B + ∠C = 180°
Put ∠C = 90°
∠A + ∠B + 90° = 180°
∠A + ∠B = 90°
Taking cos with each term.
cosA+cosB = cos (90)
cosA+cosB = 0
cosB=-sinA
Hence, cosB = sinA.
