A.
Explanation: The bigger the negative number, the lower the number actually is.
Answer: she should get 30.45 miles per gallon with her new tyres.
Step-by-step explanation:
After buying the Dunlop tires at a local Goodyear store, the salesperson told her that her mileage would increase by 5%.
If before this purchase, Maria was getting 29 mpg, it means that the amount by which her mileage will increase is
5/100 × 29 = 0.05 × 29 = 1.45 miles per gallon.
Therefore, the number of mileage that she should be getting with the new tires would be
29 + 1.45 = 30.45 miles per gallon.
Answer:
The correct answer is first option. 270 m³
Step-by-step explanation:
Formula:
Volume of prism = Base area * Height
Area of triangle = bh/2 where b - base and h - height
From the figure we can see that height of prism = 36 m
Base is a right angled triangle with base 5 m and height = 3 m
<u>To find the Base area</u>
Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5
<u>To find the volume of prism</u>
Volume = Base area * height = 7.5 * 36 = 270 m³
Therefore the correct answer is first option . 270 m³
Answer:
x = 2, -4
Step-by-step explanation:
4x^2 + 8x – 32 = 0
Divide by 4
x^2 + 2x – 8 = 0
Add 8 to each side
x^2 + 2x = 8
Take the coefficient of x
2
Divide by 2
2/2 =1
Square it
1^2=1
Add it to each side
x^2+2x+1 = 8+1
(x+1)^2 = 9
Take the square root of each side
sqrt((x+1)^2) = ±sqrt(9)
x+1 = ±3
Subtract 1 from each side
x = -1±3
x = -1+3, -1-3
x = 2, -4
Answer:
n=6
Step-by-step explanation:
25=n+8+11
25=n+19
-n=19-25
-n=-6
n=6
