Ajay's car used 314 gallons of gas on a trip to the beach. Assume 1 gallon = 3.8 liters. What is the best estimate of the number of liters Ajay's car used?

Answers

Answer

Find out the what is the best estimate of the number of liters Ajay's car used .

To prove

As given

Ajay's car used 314 gallons of gas on a trip to the beach.

Assume 1 gallon = 3.8 liters

Than

The number of liters Ajay's car used = 314 × 3.8

                                                             = 1193.2 litres

Therefore 1193.2 litres Ajay's car used .

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

A dilation with a scale factor less than 1 and then a reflection

To this point, we've encountered four kinds of symmetry:

Reflection, rotation, translation, and glide-reflection.

These symmetries are rigid motions as a result of they move a figure whereas conserving its size and shape.

All transformations are isometric. Dilation may be a non-isometric transformation. A stretch isn't a similarity transformation.

Dilations, rotations, reflections, and translations are all similar transformations. Since rotation, reflection, and translation are rigid motions, they preserve each size and shape, whereas dilation solely ensures that the form is preserved.

the multiplier is outlined as the magnitude relation of the dimensions of the new image to the size of the previous image.

the middle of dilation may be a mounted purpose within the plane.

supported the dimensions issue and therefore the centre of dilation, the dilation transformation is defined.

The complete question is :

Which composition of similarity transformations maps polygon ABCD to polygon A'B'C'D'?

a dilation with a scale factor less than 1 and then a reflection

a dilation with a scale factor less than 1 and then a translation

a dilation with a scale factor greater than 1 and then a reflection

a dilation with a scale factor greater than 1 and then a translation

Answer:

Hey there!


Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C. 


Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is . 


Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down. 


The answer will be B, "a dilation with a scale factor of  and then a translation."




At San Jacinto Middle School there are 528 students and 22 teachers. What is the ratio of students to teachers at this Middle School?

Answers

Answer:

528:22

Step-by-step explanation:

528 students : 22 teachers

                     ^

                      To

Final answer:

The ratio of students to teachers at San Jacinto Middle School is 264 : 11, which means for every 11 teachers, there are 264 students.

Explanation:

The subject of the question is Mathematics and it pertains to the concept of ratios. Ratios are used to compare two or more numbers. In this context, we are given the total number of students and teachers at San Jacinto Middle School and asked to find the ratio of students to teachers. To calculate this, we divide the number of students by the number of teachers.

Here's how you do it step-by-step: The school has 528 students and 22 teachers. So, the ratio would be 528 : 22. This ratio can be simplified by dividing both numbers by their greatest common divisor, which is 2 in this case. Hence, the simplified ratio is 264 : 11.

So, the ratio of students to teachers at San Jacinto Middle School is 264 : 11. This means for every 11 teachers, there are 264 students.
