Answer:

The cost of a candy bar is $0.75.

Step-by-step explanation:

With the provided first sentence preceded along the lines, 'total cost of a candy bar and a bag of chips is $1.70.'

--Intially, determine the quotient of 1.70 and the two quantities.

+ Result should be 0.85

Thus symbolizing .85 is the valid price of a candy bar and a bag of chips.

------------------------- Although, we are not done. -----------------------------------

Let's take the second sentence into account.

"If the cost of a candy bar and 2 bags of chips is $2.45, what is the cost of a candy bar?"

Determine the sum of .75 and (.85*2)

Alert: .75 came from subtracting 10 from the intial .85

Thus the sum is $2.45, which was stated earlier as the cost of a candy bar and 2 bags of chips.

melamori03 [73]

Answer:

a person travel 50 ft from the bottom to the top of the escalator

Step-by-step explanation:

An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle

The escalator forms a right angle triangle

opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse

let x be the hypotenuse

sin(theta)=\frac{opposite}{hypotenuse}

sin(30)=\frac{25}{x}\\x sin(30)= 25\\x=\frac{25}{sin(30)} \\x=50\\

a person travel 50 ft from the bottom to the top of the escalator

There were 3,260 visitors to a county fair on Friday. On Saturday the number of visitors to the fair increased by 15%. Fair orga
KonstantinChe [14]

Answer:

163

Step-by-step explanation:

Given the following :

Number of visitors on Friday = 3,260

Number increased by 15% on Saturday

Projected percentage increase on Saturday = 20%

Actual percentage increase in number of visitors = 15%

Number of visitors on Saturday :

(100 + 15)% × 3260

115% * 3260

(115/100) * 3260

= 3749 visitors

Projected percentage increase = 20%

Projected number:

((100 + 20)% * 3260

120% * 3260

(120/100) * 3260

= 3912

Difference : (3912 - 3749) = 163
