Im not sure but i think its d
Answer: 21/40
Step-by-step explanation:
25+18=?The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(2/5, 1/8) = 40
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(25×88)+(18×55)=?
Complete the multiplication and the equation becomes
1640+540=?
The two fractions now have like denominators so you can add the numerators.
Then:
16+540=2140
This fraction cannot be reduced.
Therefore:
25+18=2140
The Lateral Area of a cone, or the curved wrapping of the cone, can be found by this formula:

The "r" stands for radius length, and the "l" stands for slant height (that is the official symbol). We are given that the radius length is 8 so we can plug that in.

The slant height is 17. (Slant height is the distance from the vertex point of a cone to any point on the circumference of its circle base).

8x17
Simplify

136 cm squared
I'm not quite sure what DP is, but if it means exact value leave the pi symbol. Pi is the ratio of the circumference to the diameter, so 3.14 is not necessarily the most exact in all circles. Hope this helps!
Answer:
0.72 is the same as 72100 (try putting both into a calculator!) as you can view 1.00 as 11 . Reducing the fraction gives you 72100 = 1825 .
