10.5, 11, 11.5, 12, 12.5...this is an arithmetic sequence with a common difference of 0.5
an = a1 + (n - 1) * d
n = term to find = 23
a1 = first term = 10.5
d = common difference = 0.5
sub and solve
a(23) = 10.5 + (23 - 1) * 0.5
a(23) = 10.5 + 22 * 0.5
a(23) = 10.5 + 11
a(23) = 21.5 <===
Answer:
251.5 cm
Step-by-step explanation:
1 m = 100 cm
1 cm = 10 mm
2 m + 50 cm + 15 mm =
= 2 m * (100 cm)/m + 50 cm + 15 mm * (1 cm)/(10 mm)
= 200 cm + 50 cm + 1.5 cm
= 251.5 cm
Andy because 4 and 4 are the same numbers. If one of the numbers was 4.1 that would have been uneven.
GH GI and HI are parallel to CB, AB and AC respectivele
m< A = 180 - 40 - 61 = 79 degrees
m < IHB = 79 ( < A and <IHB are corresponding angles)
and m < x = m < IHB) = 79 degrees ( < x and < IHB are internal alternate angles)
Answer is 79 degree
Answer:
B. 8
Step-by-step explanation:
Start Fraction y minus 5 over 3 End Fraction= 1
This statement above is written Mathematically as:
y - 5/3 = 1
We solve the Equation below
Step 1
y - 5/3 = 1
We cross Multiply
y - 5 = 3 × 1
y - 5 = 3
Step 2
Add 5 to both sides
y - 5 = 3
y - 5 + 5 = 3 + 5
y = 8
Option b is the correct answer
