Find the sum then select the correct answer

Mathematics
1 answer:
blagie [28]3 years ago
5 0

Answer:

D. 5 4/9

Step-by-step explanation:

Ignore the whole numbers for now and just pay attention to the fractions. All the fractions have the same denominator, so add the numerators like you would any other numbers.

1-2 = -1

-1 + 5 = 4

So that gives you 4/9.

Add the whole numbers to get 5.

5 4/9

Hiii umm yeah i need help on this its about direct variation equations
taurus [48]

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

The area of a rectangle is 256.5m.  If the length is 18m what is the perimeter of the rectangle?
irga5000 [103]
The area of a rectangle equals length times height. (A=LH)

A=256.5 L=18

Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)

next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.

So, it is 256.5/18 equaling H

256.5 divided by 18 is... 14.25

That means the height is 14.25 an the length is 18.

the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.

So you have two sides that are 14.25 and two that are 18 meters long.

14.25+14.25+18+18 equals the perimeter then.

So the answer would be... 64.5!

Explain the difference between using the sine ratio to solve for a missing angle in a right triangle versus using the cosecant r
oksano4ka [1.4K]

Answer:

The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.

To find a missing angle using sine, you would need to use the inverse of sine. For example,  if the sine was  \frac{30}{40}, to find the angle you would need to find sin⁻¹ of  \frac{30}{40} which is x =  sin⁻¹ (0.75). Therefore x equals approximately 49°.
