Answer:
When you say that, I think directly to Triangles. SO i am going to state that.
There is acute: Less than 90 degrees
There is Obtuse: more than 90 degrees
There is Right: 90 degrees
Answer:
m∠A and m∠B = 130°
m∠D = 50°
Step-by-step explanation:
If all angles equal 360° and angles A and B are equal then we know the A + D and B + C equal 180° then it's simple subtraction to figure out the degrees of all the angles
Answer:
Dividing a whole number by a fraction you would just multiply the bottom number of the fraction by the whole number.
Step-by-step explanation:
(here is how to divide a fraction by a whole number, if you need help on that also.)
1. Turn the whole number into a fraction. ( ex: 2=2/1)
2. Multiply the fraction by the whole number fraction.
3. Multiply the tops together and the bottoms together
Dividing A Fraction By A Fraction
1. Arrange the equation
2. Keep the first fraction
3. Change the sign
4. flip the fraction
5. Multiply the tops together and the bottoms together
1) Dimensiones of the cardboard:
length: 10 inches
width: 8 inches
2) dimensions of the squares cut
length: x
width: x
3) dimensions of the box:
length of the base = 10 - 2x
width of the base = 8 - 2x
height = x
4) Volume of the box
V = (10 - 2x) (8 - 2x) x = x [80 - 20x - 16x + 4x^2] = x [ 80 - 36x + 4x^2 ] =
V = 80x - 36x^2 + 4x^3
5) Maximum volume => derivative of V, V' = 0
V' = 80 - 72x + 12x^2 = 0
6) Solve the equation
Divide by 4 => 3x^2 - 18x + 20 = 0
Use the quadratic formula: x = 1.47 and x = 4.53 (this is not valid)
So, the answer is the option C. 1.5 inches.
1 kilometer= 1000 meters
3x1000= 3000 meters
3000/ 25= 120 pool lengths
