Answer:
C
Step-by-step explanation:
16 : 12
x : 6
- multiply 16*6 and divide by the number multiplying with the unknown (12)
(16*6)/12 = 8
- area of triangle is 1/2 h*b
so 1/2 * (16*8) = 64
Answer:
1)The rocket hit the ground at 
2)The maximum height of the rocket = 12.468 feet
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equation
y = -2 x² + 5 x + 7 ...(i)
Differentiating equation (i) with respective to 'x' , we get
Equating zero
⇒ -4 x +5 =0
⇒ -4 x = -5
⇒
<em> The rocket hit the ground at </em><em></em>
<u><em>Step(ii):</em></u>-
...(ii)
Again differentiating equation (ii) with respective to 'x' , we get
The maximum height at x = 
y = -2 x² + 5 x + 7
<em>The maximum height of the rocket = 12.468 feet</em>
First find the area of the triangle at the end.
Area of a triangle is 1/2 x base x height.
The triangle is a right triangle with a base of 4 and height of 3
area = 1/2 x 4 x 3 = 6 square cm
Now to find the volume multiply the area of the triangle by the length of the prism.
volume = 6 square cm x 11 cm = 66 cubic cm.
answer: 66 cm^3
Answer:
<h2>
Sales price of jeans is $35</h2>
Step-by-step explanation:
Step one:
given
percentage of discount= 30%
Regular price of jeans= $49.99
Required:
the price of the jeans after the discount is deducted
Step two;
let us solve for the amount of the 30% discount
=30/100*49.99
=0.3*49.99
=14.997
=$15 approx.
Hence the deduction in discount is $15
therefore the sale price after the discount is
=49.99-15
=$35
Answer:
Joey ran 39 yards
Step-by-step explanation:
