7 yrds/sec because in the course of two seconds, he runs 14 yrds divide that by 2 to get 7 yrds/sec. you can allo chech with the next time which is 3 seconds more and he goes 21 yards more.
Answer:
a = 33cm
b = 33cm
c = 11cm
Step-by-step explanation:
Let us say that the sides of the triangle are <em>a, b and c</em>
The perimeter of a triangle can be calculated by adding all three sides of the triangle.
Perimeter = <em>a + b + c</em>
<em />
Let side <em>c</em> be the shortest side of the triangle.
From the statement "Each of the two longer sides of the triangle is three times as long as the shortest side" we can have that
<em>a = 3c and b = 3c</em>
We can input these values into the perimeter of the triangle
Perimeter = <em>3c + 3c + c = 77</em>
<em>Perimeter = 7c = 77</em>
<em>c = 11</em>
The shortest side, c is = 11 cm
side a is 3 X 11 = 33cm
side b = 3 X 11 = 33 cm
Answer:
(10,8)
Step-by-step explanation:
Symmetry over x axis: you keep x, but change the sign of y value.
So, the symmetric of (10,-8) is (10,8)
Answer:
Step-by-step explanation:
we know that
The triangle HPY is a right triangle (because the angle ∠HYP is a right angle)
Applying the Pythagorean Theorem
substitute the given values
Solve for HY
Answer:
20% is your answer
Step-by-step explanation:
You take the smallest number that can be multiplied 35 to get a whole number which in this is case is 20 because 20 ÷ 100 = 0.2 × 35 = 7
