Answer: $1.90
explanation: bc you would round 92 to 90
The radii of the circle increases by 7.5 cm each ring: 7.5 cm, 15.0 cm, 22.5 cm, and 30.0 cm.
The area if the red target is the area of the largest circle minus the second to the largest circle plus the area of the third largest circle minus the area of the smaller circle
A=pi(30.0)^2 - pi(22.5)^2 + pi(15.0)^2- pi(7.5)^2
A=900pi-506.25pi+225pi-56.25pi
A=562.5pi is approximately 1767 cm^2
Answer:
x = 1 / 2 ( or ) 0.5
Step-by-step explanation:
4x - y = 5
Substitute the value of y = - 3 in the given equation,
4x - ( - 3 ) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2 / 4
x = 1 / 2 ( in terms of fraction )
( or )
x = 0.5 ( in terms of decimal )
Note : -
- ( - 3 ) can be written as - 1 x ( - 3 ).
When a negative number is multiplied with another negative number, the result will be positive number.
Hence,
- ( - 3 ) = + 3
Answer:
in i would say 6 to 7 months
Step-by-step explanation:
Answer:
8200+1894.40 = $10,094.40
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
<em>I = P x r x t</em>
<em>Where:
</em>
<em>
</em>
P is the principal amount, $8200.00.
r is the interest rate, 4.4% per year, or in decimal form, 4.4/100=0.044.
t is the time involved, 5.5....year(s) time periods.
So, t is 5.5....year time periods.
To find the simple interest, we multiply 8200 × 0.044 × 5.5 to get that:
The interest is: $1984.40 + add to Investment ($8000) and you'll get the answer.
