Okay so process of elimination. The first option isn't correct because the sum of the interior angles for any triangle is always 180 degrees. x would be 25 degrees for ABC because 90+65=155 and 180-155=25. Y would be 95 degrees for DEF because 65+20=85 and 180-85=95, so y does not equal 90 degrees. For B, No side lengths are given. C is also not the correct answer so the answer is D. I can link you to another brainly post that has the same question or a similar with an explanation on determining the answer if you'd like :)
34). take the value on the right and subtract the value on the left.
PQ = -52 - -137 = 85
QR = 91 - -52 = 143
36). if M is the midpoint of LN, then M divided the segment in to 2 equal pieces. Thus, LM =LN.
or,. 8(x-2)=4(x+2)
8x-16=4x+8
4x=24
x=6
LM is 32,. LN= 64
Answer:
3) B. 77 flowers
4) A. 62.8
Step-by-step explanation:
3) First find the area. The area of a circular flower bed is found using the formula for a circle A = πr². Here the diameter is 14 so r =7.
Substitute r = 7.
A = π(7)² = 49π = 153.86 square feet.
Each flower requires 2 square feet.
Divide the area by 2 for the number of flowers.
153.86 / 2 = 76.93 = 77
4) First find the area of the entire circle. The area is found using the formula for a circle A = πr².
Substitute r = 6.
A = π(6)² = 36π = 113.04 square feet.
Now find the area of the small circle inside. Then subtract the two areas.
The area is found using the formula for a circle A = πr².
Substitute r = 4.
A = π(4)² = 16π = 50.24 square feet.
The shaded area is 113.04 - 50.24 = 62.8.
To convert all fractions to decimals there are two simple steps
1. Divide the numerator by the denominator
2. Round to the nearest tenth, hundredth, thousandth whatever. (If Necessary However)
But to get 2/5 to a decimal just divide 2 ÷5 by the 5.
Which equals 0.4
Answer:
its 2 4/9
Step-by-step explanation:
because i did trial and error, i converted all the fractions into decimals until one of the conversions was equal to 2.444444444444...infinite
