Answer:

74 cm would a ribbon need to be to go all the way around the edge of the top of the box .

Step-by-step explanation:

Formula

Perimeter of a rectangle = 2 (Length + Breadth)

As given

The rectangular top of a small box has dimensions of 140 mm by 230 mm.

Perimeter of the rectangle box top = 2 × (140 + 230)

                                                          = 2 × 370

                                                          = 740 mm

As

1 mm = 0.1 cm

Now change into 740 mm into cm.

740 mm = 0.1 × 740  

              = 74 cm

Perimeter of the rectangle box top = 74 cm

Therefore 74 cm would a ribbon need to be to go all the way around the edge of the top of the box .

Which is greater 11/16 or 3/4
Anettt [7]
To compare fractions, we need to have the same denominator
The least common multiple is 16
\frac{11}{16} 
to change \frac{3}{4}, we should multiply the numerator and denominator by 4
\frac{3*4}{4*4} = \frac{12}{16}

\frac{11}{16} < \frac{12}{16}

so basically, \frac{12}{16} is greater than \frac{11}{16}
which means \frac{3}{4} is greater

\frac{3}{4} is greater

In the diagram, GH bisects FGI. A. Solve for x and find m FGH. B. Find m HGI. C.find m FGI. A. X=_(simplify your answer)
Sophie [7]

Answer:

Part A) x=9 and m∠FGH=29°

Part B) m∠HGI=29°

Part C) m∠FGI=58°

Step-by-step explanation:

Part A) Solve for x and find m∠FGH

we know that

m∠FGI=m∠FGH+m∠HGI

If GH bisects FGI

then

m∠FGH=m∠HGI

substitute the values

4x-7=5x-16

solve for x

5x-4x=16-7

x=9

m∠FGH=4x-7

m∠FGH=4(9)-7=29°

Part B) Find the measure of angle HGI

m∠HGI=5x-16

Remember that

m∠FGH=m∠HGI

Verify

m∠HGI=5(9)-16=29° -----> is correct

Part C) Find the measure of angle FGI

m∠FGI=m∠FGH+m∠HGI

substitute the values

m∠FGI=29°+29°=58°

Determine the sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a me
zaharov [31]

The sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of x =2. is A. -0.7.

Given:

Random number=10

mean of x=2

population=125

mean of p=2.7

Using this formula

Sampling error=x− μ

Where:

x= sample mean=2

μ=population mean=2.7

Let plug in the formula

Sampling error=2-2.7

Sampling error=-0.7

Inconclusion the sampling error is A.-0.7.
