Answer:
840
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 14 - 7 = 21 - 14 = 7
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 7 , thus
= 7 + (119 × 7 ) = 7 + 833 = 840
Assuming that the base is 5 cm and the height is 12 cm, so
by dilating the legs by a scale factor of 2/3, the new dimensions are:
base = 5 cm * (2 / 3) = 10/3 cm
height = 12 cm * (2 / 3) = 8 cm
So the area of a right triangle is calculated using the
formula:
A = b h / 2
A = (10/3) * 8 / 2
<span>A = 13.33 cm^2</span>
Answer:
120
Step-by-step explanation:
75-15=60. (Edit) Just realized that she spent her allowance that week, so it would be 120 because you need to multiply.
3/8 is bigger than 3/10. In maths 10ths are smaller than 8ths. If both have three parts it means that 3/8 must be bigger
Answer:
65 centimeters per second = 0.65 meter per second
Step-by-step explanation:
So, 65 centimeters per second = 65100 = 0.65 meter per second. To calculate a centimeter Per second value to the corresponding value in m/s, just multiply the quantity in cm/s by 0.01 (the conversion factor).
