Answer:

35.5cm

Step-by-step explanation:

The perimeter (P) is calculated as

P = (2 × 6.75 ) + (2 × \sqrt{121}121 )

  = 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm

Answer:

35.5 cm

Step-by-step explanation:

The perimeter (P) is calculated as

P = (2 × 6.75 ) + (2 × \sqrt{121} )

  = 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm

Fynjy0 [20]

Answer:

x = 7

Step-by-step explanation:

Remember that the axis of symmetry (a vertical line that passes through the vertex) is exactly halfway between the two x-intercepts.  Thus, the x-coordinate of the vertex is 7.

Yes they do. Notice that for each step in x there a +4 in y. If you want an equation we can set it up with the inforation given
y = 4x
Yes theres a relationship because for every meter she runs it takes her 4 minutes for each.

Y = 60x +150

we put our ^0 mph as our Multiplier os x and since Alfred already traveled the 150 miles... that is just added on.

Given a right triangle with legs a, b and hypotenuse c, solve for b if a= 72 and c= 75
kotykmax [81]

Answer:

The answer is a. 21.

Step-by-step explanation:

We solve this question by using Pythagoras theorem to relate the sides of a right angled triangle.

Here,

Hypotenuse of the given triangle(c)=75

Two sides of right angled triangle are:

a=72

b=?

Then,

for a given right angled triangle abc,

Using Pythagoras theorem,

c=\sqrt{a^{2} +b^{2} }

Squaring on both sides,

c^{2} =a^{2}+b^{2}

or,75^{2}=72^{2}+b^{2}

or, b^{2}=75^{2}-72^{2}

or,b^{2}=5625- 5184

or,b^{2} =441

∴b=21

So, the value of b is obtained to 21 by the use of Pythagoras theorem.

Denver, Engle and Fido are all dogs who eat differing amounts of dog food.
alekssr [168]

Answer:

25%

Step-by-step explanation:

If Denver gets 8/19 of the food, 11/19 of the food is left between Engle and Fido.

If the food is shared in a ratio of 6 : 2 between the pair, Engle gets 6/8 and Fido gets 2/8.

Thus, 2/8 = 25%.
