Answer:
To find the missing side we need to calculate the sum of the two given sides and then subtract that from the perimeter.
7a - 11b - (2a + b + a - 9b)
= 7a - 11b - (3a - 8b)
= 7a - 3a - 11b + 8b
= 4a - 3b
Answer:
11
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. The value of x is the same as the length of the other half of the diagonal:
x = 11
Answer:
The cost of one hot dog can't be determine from the given condition
Step-by-step explanation:
From the question,
Total cost of four hot dogs and three bags of candy is $14.37 and twelve hot dogs and nine bags of candy is $24.74.
So,
Let the number of hot dog be x
and the number of bags of candy be y.
According to question,
Equations formed by given statement are,
.................(1)
.................(2)
Here, these are the linear equation in two variables says x & y.
When ,
≠ = gives Unique solution.
= = gives Infinite many solutions.
= ≠ gives No solution.
From Equation (1) & (2) we get ,
= ≠
This condition says that the given equation have no solution.
Hence the cost of one hot dog can't be determine from the given condition.
Given BD and AC is a diameter of the circle:
We need to find the following:
1. measure of the arc BA
So,
the measure of the minor arc BA = 44
The measure of the major arc BA = 360 - 44 = 316
2. the measure of the arc ACB = 360 - 44 = 316
3. The arc BCD is a semicircle of the circle
So, the measure of the arc BCD = 180
A 10-inch candle burns at a constant rate of 1 inch per hour.
Rule in words: To determine the height of the candle multiply the number of
hours that the candle burns by 1 inch per hour, and subtract the product from
the candle’s initial height (10 inches).
Rule in Equation: If y represents the height of the candle after x hours of
burning, then the relationship can be expressed as an equation in the form y
= mx + b, where m represents the rate at which the candle burns (1 inch per
hour) and b represents the initial height of the candle (10 inches).
Height of Candle = Rate at which it Burns • Number of Hours Burned +
Initial Height
y = -1 • x + 10, or y = 10 -1x
