1. ANSWER: You can solve an area of a triangle by the base and height by using the formula: A=1/2*b*h, where A= Area, b= base, and h=height.
2. ANSWER: First, use the formula: A=1/*b*h. Then substitute those variables to get A=1/2*15.25*18. Then, solve to find the area. 15.25*18=274.5. 1/2*274.5=137.25.
Therefore, the answer is Area=137.25 inches squared!

Vertex=(0,0)
directrix is x=2.5
or x-2.5=0
so focus S is (-2.5,0)
let P(x,y)be any point on the parabola.
Let M be the foot of perpendicular from P(x,y) on the directrix.
then SP=PM
The ratio of orange concentrate to water is 1 : 1
• Ratio in maths is defines as an ordered pair of numbers p and q, written p/q where value of q is not equal to 0. A proportion in maths is an equation In which two ratios are made equal to each other.
• For example, if there are 3 oranges and 5 lemons in a bowl of fruit, then the ratio of oranges to lemons is 3 :5
According to the question
Let the orange juice mixture be x ml
We are given that half of it is orange concentrate = 0.5x
And the other half is water = x – 0.5x =0.5x
We need to find ratio of orange concentrate to water
Orange concentrate = 0.5x
Water = 0.5x
Ratio = 0.5x/0.5x
= 1/1
= 1 : 1
Hence Proved, the ratio of orange concentrate to water is 1 : 1

400 divided by 10 equals 40 to the third power is <span>64000</span>
Answer: 1) Pizzeria must sell 78 pizzas for receiving the bonus.
2) The number of pizzas sold is decreased by Approximately 7.69 %.
Step-by-step explanation:
1) The number of pizza sold yesterday = 65,
The target for receiving the bonus = 20% more than the number of pizza sold yesterday
= 20% more than 65,
= 65 + 20% of 65 ( 1% = 0.01 ⇒ 20% = 0.2 )
= 65 + 0.2 × 65
= 65 + 13 = 78.
Hence, they must sell 78 pizzas for receiving the bonus.
2) If the actual number of pizza sold today = 60
⇒ Total reduction in the number of pizza = 65 - 60
= 5
Thus, the percentage decrease in the number of pizza
