Answer:
a. x divided by 3
Step-by-step explanation:
because if Tyler has 3 times more books than Mai, then Mai has 3 times fewer books than Tyler.
Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
<u>1st pic:</u> 
(write equation) Cos 27 (cos 27 = 0.89) = 
(new equation) 0. 89 =
(multiply 20 on both sides) 0.89 x 20 = x 20
(solve) 17.8 = x
<u>2nd pic:</u> 
(write equation) tan 40 (tan 40 = 0.84) = 
(new equation) 0.84 =
(multiply 32 on both sides) 0.84 x 20 = x 20
(solve) 16.8 = x
<u>3rd pic:</u>
(write equation) cos 55 (cos 55 = 0.57) = 
(new equation) 0.57 =
(multiply 16 on both sides) 0.57 x 16 = x 16
(solve) 9.1 = x
<u>4th pic:</u>
(write eqaution) tan 42 (tan 42 = 0.90) = 
(new equation) 0.90 =
(multiply 15 on both sides) 0.90 x 15 = x 15
(solve) 13.5 = x
Step-by-step explanation:
4+2+2+4+5 - 17
in nearest ten - 100 but i am not sure
Answer:
1) the factored form is y= ( x-5 ) ( x+4 )
2) the vertex is (4.5, -0.25)
3) the y intercept is when x equals 0 so it is at (0,20)
4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)
5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
Answer:
Initial dive: - 248 (below the surface which represents '0')
Second dive: -10
Present depth -248 + -10 = -258 feet below the surface
Step-by-step explanation:
We can use negative integers to represent real-world scenarios such as in elevation and descent, bank account balances and temperatures. In this case, because a diver is descending below the surface of the water, the surface of the water represents the '0' and going down into the water would be negative integers. So, his initial dive is 248 down, or negative 248 (-248), he then dives down an additional 10 feet, or negative 10 (-10). Since the second dive is in addition to his initial dive, we add the two integers together:
-248 + -10 = -258 feet
