Answer:
6
Step-by-step explanation:
The first number: a
The second number: b
The third number: c
a+b+c=72
b=7a
b-c=18
⇒a=6; b=42;
c= 24
Answer:
It will take them 15 minutes.
Step-by-step explanation:
1. Since you are given the information that the two typists are typing a certain amount of words in the same time frame (ie. one minute), you can add the two values together to obtain the total number of words the typists would type together in one minute:
95 + 98 = 193 words
2. To calculate how many minutes it would take them to type 2,895 words, you would simply take this total number of words and divide it by the number of words they collectively type in one minute (found in 1.). Thus:
2895/193 = 15
Therefor, it will take them 15 minutes to type 2,895 words.
Answer:
86 units squared.
Step-by-step explanation:
If the perimeter is 30 and it is an equilateral triangle, the means each side of the triangle is equal so they must all be 10 units longs. Since the line XA is part of the quadrilateral, lines FL and XA of the rectangle must be 10 units long. But we still don't know the length of the sides. Within the box are two right triangles, FZX and ZLA. We know the the length of the hypotenuse which is 10 units, and the base which is 5 units. Then we use the Pythagorean Theorem so find the length of the sides. After we do that we get about 8.6. Now we can multiply the length and width to get an area of 86.
