Answer:
a. 78.6 square feet
b. $7.86
Step-by-step explanation:
a. This simply asks us to calculate the area of the 10 feet diameter pool
Formula for area of circle is ;
pi * r^2 = pi * d^2/4
so Area = 22/7 * 10^2/4 = 78.60 square feet
b. This will be the area of the blanket multiplied by the price per square foot of the blanket
Mathematically, we have that as;
78.60 * 0.1 = $7.86
The angles of a triangle should add up to 180 degrees. in the left triangle, you should find the 3rd angle
75 + 50 + y = 180
125 + y = 180
y = 55
vertical angles are congruent, so the left angle on the right triangle will also be 55 degrees.
then you do the same thing to find x.
85 + 55 + x = 180
140 + x = 180
x = 40
Answer:
Test's average-95
Homework's average-96.67
Step-by-step explanation:
Average is mathematically defined as the sum of the values divided by the total number of values and is expressed as:
The Tests' average is calculated as:
Hence, the Tests' average is 95
#The Homework's average is calculated as:
Hence, the Homework's average is 96.67
Answer:
Step-by-step explanation:
ABC and DEF are parallel lines. So, ∠ABE and ∠BED are co interior angles.
∠ABE + ∠BED = 180 {SUM OF CO INTERIOR ANGLE IS 180}
∠ABE+ 110.2 = 180
∠ABE = 180 - 110.2
∠ABE = 69.8
Now, ABC is straight line
∠ABE + ∠EBG + ∠CBG = 180
69.8 + ∠EBG + 34.8 = 180
104.6 + ∠EBG = 180
∠EBG = 180 - 104.6
∠EBG = 75.4
Again, DEF is straight line
∠DEB + ∠BEG + ∠GEF = 180
110.2 + ∠BEG + 25.6 = 180
∠BEG + 135.8 = 180
∠BEG = 180 - 135.8
∠BEG = 44.2
In triangle BEG,
∠BEG + x + ∠EBG = 180 { sum of all angles of triangle is 180}
44.2 + x + 75.4 = 180
x + 119.6 = 180
x = 180 - 119.6
x = 60.4
