In a stairway, the slope of the handrail is the - 1

Answers

Answer 1
Answer:

The slope of the handrail is 2/3. The correct answer is: c. 2/3

To find the slope of the handrail, we can use the given information that the slope is the ratio of the riser to the tread.

Slope = Riser / Tread

Given that the tread is 12 inches long (Tread = 12 inches) and the riser is 8 inches long (Riser = 8 inches), we can substitute these values into the formula:

Slope = 8 inches / 12 inches

Now, we can simplify the ratio:

Slope = 2/3

So, the slope of the handrail is 2/3. The correct answer is:

c. 2/3

Jan's pencil is 8.5 cm long. Ted's pencil is longer. type a demical that could represent the length of ted's pencil

Answers

Answer: Ted's pencil could be 8.6 cm.

Step-by- Step explanation:

Since we have given that

Length of Jan's pencil= 8.5 cm

According to the question, we know that Ted's pencil is longer.

So, it must be larger in value than 8.5 cm .

So, it can be any decimal number greater than 8.5 cm

Hence, Ted's pencil could be 8.6 cm.
If Jan's pencil is 8.5 cm long, and Ted's is longer, anything larger than 8.5 should work.

Examples - 8.9 c.m.

What is the best approximation of the solution to the system to the nearest integer values? 2x-3y=-6 x+2y=8 plz help

Answers

2x-3y=-6
x+2y=8 
you subtract the 2y from the second equation to get x by itself so you can use the rule of substitution. 
2x-3y=-6
x=-2y+8
now you take what the x is equal to and plug that whole equation into the second equation
2(-2y+8)-3y=-6
now distribute your parentheses.
-4y+16-3y=-6
Add your like terms
-7y+16=-6
Subtract the 16 to one side.
-7y=-22
Divide by the -7
y=22/7
Now plug the y value (22/7) into one of the two equations to find the x value.
