The answer is 1/2 i did the test and got it right can i get brainliest please
Answers:
5. x = 1
6. y = 11.5
Step-by-step explanation:
For question 5, you can use power of a point which describes the relationship of two secants intersecting inside a circle. You get the formula:
AC * CD = BC * CE
You can substitute the values you are given to get:
2 * 4 = x * 8
This gives you x = 1
For question 6, you can use another formula in power of a point that describes two secants intersecting in the exterior of a circle. You get the formula:
GH * GJ = GI * GK
Using segment addition postulate, you get:
GJ = GH + HJ = 5 + 16 = 21
GK = GI + IK = 6 + y --> y + 6
Now, substitute into the equation from power of a point:
5 * 21 = 6 * (y + 6)
105 = 6 * (y + 6)
17.5 = y + 6
y = 11.5
Answer:
Step-by-step explanation:
Since it is a square, all four sides are equal and its perimeter is just
P=4s, so if P=8 then
4s=8, dividing each side by 4 we get
s=2
So each side of the plastic square is 2 centimeters.
Answer:
There is no question so I can not respond with a answer.
Step-by-step explanation:
Answer:
number 21: 5 ten thousands, 7 hundreds, <em><u>7</u></em><em><u> </u></em>tens and 7 ones
Step-by-step explanation:
7 tens = 70
7 ones = 7
which equals 77, if the number is 50,777, you can see the last two digits in the tens and ones place are 7 and 7.
