Answer:
1. $1,122
2. $485.25
3. $440
4. $2,047.25
Step-by-step explanation:
1. 22 feet * 17 feet = 374 square feet * $3 per square foot = $1,122
2. 17 feet * 10 feet * 4 walls = 680 square feet. 680 feet - (7ft*3ft for the door) - (2*2ft*3ft for the windows) = 647 square feet * $0.75 per square foot = $485.25
3. 374 square feet/ $88 per gallon = 4.25 gallons which rounds up to 5 gallons, and 5 gallons at a cost of $88 per gallon = $440
4. $1,122 + $485.25 + $440 = $2,047.25
A/b+c/b=(a+c)/b
make bottom number same
multiply by 1 or x/x where x=x
easy way is
if you had
a/b+c/d
multiply a/b by d/d and multiply c/d by b/b
2/5 times 4/4=8/20
2/4 times 5/5=10/20
add
8/20+10/20=(8+10)/20)=18/20=9/10
I should have simplified 2/4 to 1/2 first
Answer:
The area of rectangle is changing at the rate of 33 square inches per second.
Step-by-step explanation:
We are given the following information:
Let W be the width of the rectangle and L be the length of rectangle.
Rate of change of width = 
Rate of change of length = 
We have to find rate of change of area at W = 2 and L = 3.
Rate of change of area = 
Area of rectangle = Length × Width
Putting the values, we get
The area of rectangle is changing at the rate of 33 square inches per second.
Answer: A
Step-by-step explanation:
Looking at the conditions, we can eliminate D. An isosceles triangle has 2 equal sides. 2 cm, 3 cm, 4 cm don't have 2 equal lengths.
We can next eliminate C. C is a right scalene triangle. Even if this is a scalene triangle, the key is the work "right". Any right triangle, regardless of it's angles, always fit the Pythagorean Theorem. C does not fit the Pythagorean Theorem.
2²+3²=4²
4+9=16
13≠16
We are left with the options A and B. A and B can both be correct answers, but it is the condition given in the problem that makes A the right answer. A states acute scalene triangle. That means there is at least 1 acute angle. Technically, B is also correct, but because the problem explicitly states 29°, that makes A the correct answer.
