1. The number of triangles to the total number of shapes​

Answers

Answer:

count the number of triangles and then the total number of shapes so if there are 7 triangles and 21 shapes total the answer would be 7-21

Step-by-step explanation:

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The total number of shapes is 9. And the number of triangles is 4.

Then the ratio of the triangles to the total number of shapes will be given as,

Ratio = 4 / 9

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.

A bench is located where the shadows casted by a 16 foot tall flagpole and 40-foot tall tree meet. If the bench is 18 feet from the flag pole, find the distance from the flagpole to the tree

Answers

Answer:

The distance from the flagpole to the tree is 27 ft

Step-by-step explanation:

Similar Triangles

Since the elevation angle from which the trees cast their shadows has the same measure and given the tree and the flagpole and the ground form right angles, both triangles are similar.

Similar triangles have their corresponding side lengths proportional. The ratio between the distances from the bench to the tree and flagpole and their heights is constant, i.e.:

[tex]\displaystyle \frac{16}{18}=\frac{40}{x}[/tex]

Where x is the distance from the bench to the tree.

Solving for x:

[tex]\displaystyle x=40\cdot \frac{18}{16}[/tex]

x = 45 feet

Thus the distance from the flagpole to the tree is 45 - 18 = 27 feet

Answer is 154

Step-by-step explanation:

a) Work out the value of G
give your answer in standard form correct to 3 significant figures
b) Work out the new value of G
give your answer in standard form correct to 3 significant figures

Answers

Answer:

a. G = 4590.0

b. G = 4550.0

Step-by-step explanation:

Given that: G = [tex]\sqrt{\frac{m}{t^{2} } }[/tex]

a. m = 6.1 x [tex]10^{-5}[/tex] and t = 1.7 x [tex]10^{-6}[/tex]

Thus,

G = [tex]\sqrt{\frac{6.1*10^{-5} }{(1.7*10^{-6}) ^{2} } }[/tex]

   =  [tex]\sqrt{\frac{6.1*10^{-5}}{2.89*10^{-12} } }[/tex]

   = [tex]\sqrt{21107266.44}[/tex]

G = 4594.26452

G = 4590.0

b. m =  6.1 x [tex]10^{-5}[/tex] + ( 6.1 x [tex]10^{-5}[/tex] x 0.08)

       = 6.588 x [tex]10^{-5}[/tex]

   t = 1.7 x [tex]10^{-6}[/tex] + (1.7 x [tex]10^{-6}[/tex] x 0.05)

     = 1.785 x [tex]10^{-6}[/tex]

So that,

G = [tex]\sqrt{\frac{6.588*10^{-5} }{(1.785*10^{-6}) ^{2} } }[/tex]

   = [tex]\sqrt{\frac{6.588*10^{-5} }{3.186*10^{-12} } }[/tex]

   = [tex]\sqrt{20676505.9}[/tex]

G  = 4547.1426

Truck drivers report the mileage or the number of miles (M) traveled per gallon of gas (G) for each trip. Which driver went the farthest on one gallon of gas.

Answers

Answer:

B. Andy

Step-by-step explanation:

Kelly's mileage

This is proportional relationship, so one pair of coordinates is enough for our calculation, point (20, 50):

m = 50/20 = 2.5 gAndy's mileage

Use one pair of points from the table to calculate (15, 78.75):

m = 78.75/15 = 5.25 gRick's mileage is given:m = 4.8 g

Comparing, we see Andy's mileage is largest.

Andy will travel farther than the other drivers.
