Area of the rectangle minus area of 2 circles
Area of rectangle is 8x16
Area of circle is pi•r^2 = 3.14 x 4^2= 3.14•16
Answer is:
128 - 2(3.14•16) square inches
It is E X= 22
J LINE SUPPLEMENTARY ANGLE so
the angle is = 180 - (5x-16 ) = 180-5x +16 =196 -5x ( angle in the triangke )
the other angle in the triangle = 50 ( alt interior angles line l parallel m
then we took the triangle sum = 180
<span>196 -5x </span> + 2x +50 = 180
so x = 22
Answer:
I believe the answer is $2.25
Step-by-step explanation:
To figure this out, first you need to find 25% as a decimal. 25% as a decimal is .25 . Then, you multiply 9 by .25 . 9 * .25 = $2.25. You are saving $2.25 with the discount.
Hope this helps :)
Answer:
d. 690.1 units²
Step-by-step explanation:
1. You can use the Heron's formula to calculate the area of the triangle, which is:
![K=\sqrt{s(s-a)(s-b)(s-c)}](https://tex.z-dn.net/?f=K%3D%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D)
Where:
![s=\frac{a+b+c}{2}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7Ba%2Bb%2Bc%7D%7B2%7D)
2. Calculate
:
![s=\frac{33+51+42}{2}\\s=63](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B33%2B51%2B42%7D%7B2%7D%5C%5Cs%3D63)
3. Substitute values into the formula shown above and calculate the area, as following:
![K=\sqrt{63(63-33)(63-51)(63-42)}\\K=690.1units^{2}](https://tex.z-dn.net/?f=K%3D%5Csqrt%7B63%2863-33%29%2863-51%29%2863-42%29%7D%5C%5CK%3D690.1units%5E%7B2%7D)
4. Therefore, the area is 690.1 units².
Answer:
45 old houses
Step-by-step explanation:
new houses : old houses
3 : 9
15 : ?
(3 = 1st ratio and 9 = 2nd ratio)
To find the missing ratio, divide the first ratio from the new ratio:
15 / 3 = 5
Take the product and multiply that by the second ratio to find the missing ratio:
9 x 5 = 45
