Answer: If the 40% off coupon is used, the subtotal will be $12.69
The gratuity would be exactly $4.23 (He will probably leave $4.25)
Step-by-step explanation: To find out the amount of the discount
.40 × 21.15 = 8.46
To find the new subtotal, subtract 12.15 - 8.46 = 12.69
To figure the tip: .20 × 21.15 = 4.23
Changing the percent to a decimal means divide the 20 by 100.
Answer:
3 hours
Step-by-step explanation:
To find the number of hours the plumber was at the house, we need to solve for x.
22x + 50 = 116
22x = 116 - 50
22x = 66
22x/22 = 66/22
x = 3
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
We first solve the brackets:
(16-9) = 7
Now, we multiply it with 4
Now, we add 3 to it:
Hence, the value of expression would be 31.
Therefore, First option is correct.
Answer:
3/4
Area of the small triangle/Area of larger triangle=3/4
Area of the small triangle/Area of larger triangle=(1/2×base of small triangle×length)/(1/2×base of larger triangle×height)
3/4=(1/2×base of small triangle×height)/(1/2×base of larger triangle×height)
Since the length of the triangle are equal the base ratio of the two triangles is the same as area ratio.
