Answers

Answer:

a.  |x - 1.5| < 0.125

b.  -0.125 < x - 1.5 < 0.125

c.  1.375 < x < 1.625

d.  Bolt has to be greater than 1.375 inches and less than 1.625 inches to be within the margin of error of 0.125 inches.

e. One acceptable length for a bolt is 1.4 inches.

f. One non-acceptable length for a bold is 1.7 inches.

Step-by-step explanation:

Solve for x:

-0.125 < x - 1.5 < 0.125

-0.125 < x - 1.5     and    x - 1.5 < 0.125

1.375 < x                               x < 1.625

Write this as:   1.375 < x < 1.625

WRITE 0,000003 56 IN SCIENTIFIC NOTATION ​

Answers

Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

Steve is turning half of his backyard into a chicken pen. His backyard is a 24-meter by 45-meter rectangle. He wants to put a chicken wire fence along the west side of the yard, the south side of the yard, and along the diagonal connecting the northwest to the southeast corner of the yard. How many meters of fencing will Steve need to fully enclose this area?

Answers

The diagonal line is equal to \sqrt{24^(2) + 45^(2) } using pythagoras' theorem of a^(2) + b^(2) = c^(2). This gives us a value of 51m for the diagonal line.

TOTAL; 51+24+45=120m of fencing 

Answer:

51 meters

Step-by-step explanation:

We can use the Pythagorean Theorem to find the length of the diagonal line.

The equation for the Pythagorean Theorem is

a^2 + b^2 = c^2a  

2

+b  

2

=c  

2

a, squared, plus, b, squared, equals, c, squared

where aaa and bbb are the lengths of the two legs of the triangle, and ccc is the length of the hypotenuse.

In this case a=24,b=45,a=24,b=45,a, equals, 24, comma, b, equals, 45, comma and c=xc=xc, equals, x.

Hint #33 / 4

\begin{aligned} 24^2+45^2 & = x^2\\ 576+2025 & = x^2\\ 2601 & = x^2\\ \sqrt{2601} & = x\\ 51 & = x \end{aligned}

What is the area of this polygon?

Answers

The middle is a square with side length of 12cm

Area of the square = 12 x 12 = 144 cm^2

There are 4 triangles with base of 13cm and height of 8 cm

Area of triangle = 1/2 x base x height

Area = 1/2 x 12 x 8 = 48cm^2 each

48 x 4 = 192 cm^2

Total area = 144 + 192 = 336 cm^2
