1. Yes it is a right triangle.
1.25^2 = 1^2 + 0.75^2
1.5625 = 1 + 0.5625
1.5625 = 1.5625
Both sides are equivalent therefore it is a right triangle.

2. No it is not a right triangle.
28^2 = 21^2 + 20^2
782 = 441 + 400
782 does not equal 841 therefore it is not a right triangle.

Y=-3x2 + x + 17<br> axis of symmetry?
cupoosta [38]

Answer:

1/6

Step-by-step explanation:

The x-coordinate of the vertex is always the x-value of the axis of symmetry. The vertex can be found by x=\frac{-b}{2a}. If we look at this equation as y=ax^{2} +bx+c,

b=1 and a=-3.

When you plug those values into the x equation you get x=\frac{1}{6}.

Wilton collected $8.50 in dimes and quarters while cleaning his father's truck. If the number of quarters is 3 times the number
dusya [7]

Answer:

Wilton found 10 dimes while cleaning his father's truck.

Step-by-step explanation:

Given that:

Total amount collected = $8.50 = 8.50*100 = 850 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement,

10x+25y=850     Eqn 1

y = 3x     Eqn 2

Putting y=3x in Eqn 1

10x+25(3x)=850\\10x+75x=850\\85x=850

Dividing both sides by 85

\frac{85x}{85}=\frac{850}{85}\\x=10

As x represents dimes, therefore, number of dimes is 10.

Hence,

Wilton found 10 dimes while cleaning his father's truck.
