Which pair of measurements is not equivalent?

Mathematics
1 answer:
Bingel [31]4 years ago
6 0

Answer:

750 mm, 7.5 cm

Step-by-step explanation:

Verify each case

case a) 2.5 km, 2,500 m

we know that

1 km ------> 1.000 m

so

2.5 km=2,500 m

therefore

The pair of measurements is equivalent

case b) 750 mm, 7.5 cm

we know that

1 cm ------> 10 mm m

so

7.5 cm=75 mm

therefore

<u>The pair of measurements is not equivalent</u>

case c) 3 m, 3,000 mm

we know that

1 m ------> 1.000 mm

so

3 m=3,000 mm

therefore

The pair of measurements is equivalent

case d) 120 cm, 1.2 m

we know that

1 m ------> 100 cm

so

1.2 m=120 cm

therefore

The pair of measurements is equivalent

Can you help me guys on this question?

Answer:

The missing height is approximately 78.8011 feet.

Step-by-step explanation:

To solve for the height of the kite, you need to use a trigonometry function called sine. Sine - or sin when used to calculate - is most commonly used for right triangles, and the sine of a right triangle angle is equivalent to the side opposite (or the only side of the right triangle that does not help create that angle) of the angle divided by the hypotenuse of the right triangle. So you can now create the following function to solve the height: sin(52°) = \frac{x}{100} where x represents the unknown height of the kite. From there, you can get that x = 100*sin(52°), which equals approximately 78.8011 feet. Since there isn't a specific decimal place to round to, I rounded the answer to four decimals. If your teacher asks you to round to a specific place value, use 78.8011 to get your simplified answer.

The student to faculty ratio at a small college is 17:3 the total number of students and faculty is 740. How many faculty member
larisa86 [58]

Answer:

111

Step-by-step explanation:

It is given that the student to faculty ratio at a small college is 17:3.

Let number of students and faculty members are 17x and 3x respectively.

It is given that total number of students and faculty is 740.

17x+3x=740

20x=740

Divide both sides by 20.

x=37

Number of student =17\times 37=629

Number of faculty members =3\times 37=111

Therefore, there are 111 faculty members at the college.

How do I find the measure of angle 1 and 2
Dvinal [7]

Angle 1 is a vertical angle in relation to the given angle, 117°, so it has the same measure.

Angle 2 is a corresponding angle to angle 1 where the transversal crosses parallel lines, so it has the same measure. (It is also an alternate exterior angle with respect to 117°, so has the same measure.)

∠1 = ∠2 = 117°
