Answer:
x=1 or x=−2
Step-by-step explanation:
16x2+10x−27=−6x+5
Step 1: Subtract -6x+5 from both sides.
16x2+10x−27−(−6x+5)=−6x+5−(−6x+5)
16x2+16x−32=0
Step 2: Factor left side of equation.
16(x−1)(x+2)=0
Step 3: Set factors equal to 0.
x−1=0 or x+2=0
x=1 or x=−2
The ratio table shows the costs for different lengths of silver chain. Find the unit rate in dollars per inch
Length (inches) 16 18 20 22
Cost (dollars) $36.00 $40.50 $45.00 $49.50
The unit rate is $__ per inch.
Answer:
2.25
Step-by-step explanation:
yes
The unit rate of the silver chain is $0.44 per inch.
What is the unit rate?Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.
Given here: 16 inches of silver chain costs $36 and 18 inches cost $40.50
Thus we have the unit rate( dollar/inch) =36/16=40.50/18=4/9
Therefore the unit rate is given by 4/9 or 0.444 dollar per inch.
Hence, The unit rate of the silver chain is $0.44 per inch.

A scale model of the statue of liberty is 8 inches tall. If the scale used is 1 in = 30yd. What is the actual height of the statue of liberty?
Answer: 250 yd
Step-by-step explanation:
From the question, we are informed that the scale model of the statue of liberty is 8 inches tall and that the scale used is 1 in = 30yd.
Since the scale used was 1 in = 30 yd, the actual height of the statue of liberty will be:
= 8 × 30
= 240 yd
A lift driver charges $5.25 for the first mile of the trip and$1.25 each mile after that. He charges the customer $24 for the ride.
Answer: 15 miles
Step-by-step explanation:
The equation is 5.25+1.25x=24 where x is each additional mile so to solve for x it would be 1.25x=18.75 and divide both sides to solve for x

Answer:
√35i
Step-by-step explanation:
i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.
Answer:
We know that √-1 = i, where "i" is the imaginary unit
± √(-35) = ± √(35) i
± √(35) i is the right answer.Together, teammates Pedro and Ricky got 2675 base hits last season. Pedro had 279 more hits than Ricky. How many hits did each player have?

Find the area for the given circle. Round to the nearest tenth.
113.0 ft^2
124.8 ft^2
37.7 ft^2
452.2 ft^2
Answer:
The answer is 113.0 ft^2
Step-by-step explanation:
To find the area you do pi times the radius squared, so that would be pi times 36. which equals 113.0 ft^2.
The area of a given circle is 113.0 square feet. Therefore, option A is the correct answer.
What is area of a circle?The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.
Given that, the diameter of circle is 12 feet.
Here, radius = 12/2
= 6 feet
Now, area of a circle = 3.14×6²
= 3.14×36
= 113.0 square feet
Therefore, option A is the correct answer.

Find the slope of the line on the graph below:
Slope
Answer:
The slope of the line on the graph is [tex]\frac{3}{2}[/tex].
Step-by-step explanation:
The slope of a line can be found with [tex]\frac{\Delta y}{\Delta x}[/tex]. The points (3,2) and (-1,-4) lie on the line, so we can subtitute [tex]\Delta y = -4 -2 = -6[/tex] and [tex]\Delta x = -1-3 = -4[/tex] to see that the slope equals [tex]\frac{-6}{-4} = \frac{3}{2}[/tex]. This answer makes sense because the slope is going up when [tex]x[/tex] becomes larger (the slope is positive), and we travel more in the [tex]y[/tex]-direction than in the [tex]x[/tex]-direction (the slope is greater than 1).
