I believe its either A or C
Answer:
x = -4/11
Step-by-step explanation:
add the x values.
11x+8=4
subtract 8 from each sides
11x=-4
divide by 11
x=-4/11
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
First and foremost, we should note that the value of the digit 2 in the number 135,284 is 200. Therefore, the value that is ten times as great as the value of the digit 2 in the number 135,284 would be:
= 10 × 200
= 2000
Therefore, the 2 must be in the thousands place. This can be seen in numbers such as:
172748.
Answer:
Area of circle R = 75π un² or ≈235.5 un²
Step-by-step explanation:
The problem says that m∠TRS = 120º. The total number of degrees in a circle is 360º. 120º is a third of 360º. Therefore, we can prove that the shaded sector is a third of the circle.
The problem then says that the area of the shaded sector is 25π and we have to calculate the area of the entire circle. Since we already know that the shaded sector is a third of the circle, we can simply multiply 25π by 3 in order to calculate the area of t he entire circle.
25π × 3 = 75π.
Area of circle R = 75π un² or ≈235.5 un²
