Answer:
The value of a = -12.
Step-by-step explanation:
Given that the points are Q( -6, 5) and R ( -2, 3) -
As we know that-
If a line segment AB is with endpoints (
) and (
) then the mid points C are-
<em>C = (
,
)</em>
Here,
Q( -6, 5) and R ( -2, 3)
then the midpoints C are-
( a/3, 4) = (
,
)
We have to find the value of x therefore we need to compare only x coordinate -
<em>a/3 = ( -6 - 2)/2</em>
<em>a/3 = -8/2</em>
<em>a/3 = - 4</em>
<em>a = -12</em>
Hence the value of a = -12.
Answer:
25
Step-by-step explanation:
A box contains 100 colored chips
Some are yellow and,
Some are green.
John has recorded 57 yellow chips and 19 green chips.
The ratio of yellow chips to green chips is 57:19 simplified becomes; 3:1
The number of green chis is
× 100 =
× 100 = 25
36 to the nearest hundredth is just 36
To round 36 to the nearest hundredth consider the thousandths' value of 36, which is 0 and less than 5. Therefore, the hundredths' value of 36 remains 36
Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as
then the equation relating them is
c = k
← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75
← equation of variation
When d = 324 , then
c = 1.75 ×
= 1.75 × 18 = 31.5
