D = 1/2 * (-16). That is your answer
Step-by-step explanation:
the perimeter =
4+4+6+4.5+2+4+4+2 =
30.5 cm
the area of:
• the bigger rectangle = 6×4 = 24 cm²
• the smaller triangle = 4×2 = 8cm²
• the triangle = ½×2×4 = 4cm²
the total area = 24+8+4 = 36cm²
Answer:
25.19
Step-by-step explanation:
Change the percentage into a decimal. 30% is the same as saying 30/100.
This is 30 hundredths and in decimal form, it looks like this:
0.30 since 30/100 is the same as 3/10
To find out how much of a discount he gets, multiply 0.30 times 35.99.
0.30 x 35.99 = 10.797 which rounds up to 10.80.
This means he gets 10.80 off of the original price.
To find out what the new price is, subtract that from the original price.
35.99 - 10.80 = 25.19
Answer:
5/12
Step-by-step explanation:
If you roll it twice there are 12 options. The odd numbers are 1, 3, and 5. Add 2 and 4, and that's a 5/12 chance.
15% of 27:
0.15 x 27 = 4.05
27 - 4.05 = 22.95
The sale price is $22.95
