When you use deg. rad. and grad on a calculator, what does it mean?

1 answer:

6 0

Deg - degrees (mode in degrees)
rad - radians
grad -

these are all used to find angles, especially when doing trig

I am sorry but i am not exactly sure what grad means.

Fencing encloses a rectangular backyard that measures 300 feet by 600 feet. A blueprint of the backyard is drawn on the coordina

liubo4ka [24]

Answer:

$(x-15)^2+(y-30)^2=36$

Step-by-step explanation:

we know that

The dimensions of the rectangular backyard in the actual are 300 feet by 600 feet

The dimensions of the rectangular backyard in the blueprint are 30 units by 60 units

therefore

If the radius of the circular flower garden in the actual is 60 feet

then

the radius of the circular flower garden in the blueprint is 6 units

Find the center of the radius in the blueprint

Remember that the circular flower garden is in the center o the backyard

To find out the center, determine the midpoint of the rectangular backyard

C((0+30)/2,(0+60)/2)

C(15,30)

The equation of a circle in center radius form is equal to

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center

r is the radius

we have

$(h,k)=(15,30)\\r=6\ units$

substitute

$(x-15)^2+(y-30)^2=6^2$

$(x-15)^2+(y-30)^2=36$

ASAP! A biologist is to set up an aquarium in his laboratory. He intends to buy 11 piranhas and 5 sharks. He has a budget of £20

Mars2501 [29]

Answer:

p = (200 -5s)/11

Step-by-step explanation:

I think you meant p is the price of piranhas, and a is the price of one shark.

You have:

11p + 5s = 200

11p = 200 - 5s

p = (200-5s)/11

Does that help? ;)

HELP!! REAL answers only please.

Alika [10]

Answer:

Step-by-step explanation:

So the angle of 40 is a vertical angle with the one opposite of it, meaning that the triangle on the left would have two values of 40 and 41, to find the value of the 3rd angle of the left triangle, you can subtract 40 and 41 from 180 which is the total number of degrees in a triangle to get 99, then you can find the degrees of the triangle on the right's bottom angle by subtracting 99 from 180, meaning the bottom left angle would be 81, then you can do the same to find the other angle by subtracting 114 from 180 to get 66. Lastly you can add 81 and 66 to get 147, then subtracting 147 from 180 you would get x=33

What value is equivalent to 13 − 2(1 − 15) ÷ 4? A) -38.5 B) -26 C) 7.25 D) 20

Klio2033 [76]

Answer:

D. 20

Step-by-step explanation:

13 - 2 (1-15) ÷ 4

First deal with whatever in the parentheses

13 - 2 (-14) ÷ 4

Multiply and divide from left to right

13 - (-28) ÷ 4

13 - (-7)

The negatives would cancel so add 13 and 7 to get 20
