40.4 Kilograms round to the nearest hundreth​
Romashka-Z-Leto [24]

Answer: 40.4 rounded to the nearest hundredth would be 40.40

Step-by-step explanation: There is no oneth in decimals so it goes from tenth, to hundredth, to thousandth. Since there is no number in the hundredth or thousandth's space, you would put a zero in both spots. zero in the thousandths is NOT greater than 5 so the zero in the hundredths space will stay as a zero, making the answer 40.40

The equation of a parabola is given.
Irina18 [472]

y = −1/4x^2 + 4x − 19

1. Use x = -b/2a to find x.

x = -4/2(-1/4)

x = -4/(-1/2)

x = -4/1 • (-2/1)

x = 8/1

x = 8

2. Plug x into the function to find your vertex.

Replace every x you see in the function with 8 and do the math.

Take it from here.

Circumference is 2πr or πd.
So for part 1 the diameter = 9in.
Plug in 9 into the πd formula.
π*9 = 9π in. ≈ 9*(22/7) ≈ 28.29in

For part 2 (from what I can see) they want you to find the same circumference in centimeters(cm) and use 22/7 for π so first convert the radius to cm.
9 in = 9*2.54 = 22.86cm
Next plug in the values into the Circumference formula: π*d
(22/7)*(22.86) ≈ 71.85cm

Hope this helps!

8-m/7=18 ................
Komok [63]

Answer:

m= -84

Step-by-step explanation:

Step 1- Multiply both sides by 7

42-m= 126

Step 2- Move constant to the right hand side and change its sign

-m= 126-42

Step 3- Subtract the numbers

-m= 84

Step 4- Change the signs on both sides of the equation

m= -84
