The area of a triangular flag is 132 square centimetres. Its altitude is 2 centimetres longer than twice its base. Find the leng
Anika [276]

Answer:

24 cm and 11 cm

Step-by-step explanation:

GIVEN: The area of a triangular flag is 132 \text{ cm}^2. Its altitude is 2\text{ cm} longer than twice its base.

TO FIND: lengths of the altitude and the base.

SOLUTION:

Let the altitude and the base of flag be a and b

According to the question

a=2+2b

area of triangle =\frac{1}{2}\times base \times alltitude=\frac{1}{2}a\times b

\implies \frac{1}{2}(2b+2)b=132 \Rightarrow 2b^2+2b-264

Solving equation we get

b=11   then a=24

Hence the lengths of altitude and base of triangular flag is 24 cm and 11 cm respectively.

in 2003, a gallon of gas cost $1.75. In 2013 a gallon of gas cost $3.25. Write an equation to model this situation.
djverab [1.8K]

We can easily solve this by assuming a linear equation. The general form is:

y = m x + b

where y is the price of gas, x is the year, m is the slope or increase in price every year and b is the y-intercept

We can solve the slope by:

m = (3.25 – 1.75) / (2013 – 2003)

m = 0.15

 

y = 0.15 x + b

Using any pair data, we get the b:

3.25 = 0.15 (2013) + b

b = -298.7

 

y = 0.15 x – 298.7
