Mieko said that the difference between the longest rose and the shortest rose is 1 inch. Is she correct?

erastova [34]

Answer:

Mieko is correct

Step-by-step explanation:

Given

See attachment for complete question

Required

The length difference

Lengths with dot(s) means, there is at least 1 rose flower of that length.

So, from the attachment, we have:

$Longest = 14.0$

$Shortest = 13.0$

The difference (d) is:

$d = Longest - Shortest$

This gives:

$d = 14.0 - 13.0$

$d = 1\ in$

<em>Hence, Mieko is correct</em>

1) Shannon and Kristoph are dividing numbers written in scientific notation.

mihalych1998 [28]

Answer:

<h3>(A)</h3>

The answers will have the same value, beacuse both scientific notations have the same coefficient, 4.2 and 1.4. Also, if you mentally subtract the exponents of those powers, you would have the same exponent. So, equal coefficient and equal exponent will give the same result.

<h3>(B)</h3>

The value of each expression can be found by dividing coefficients and powers.

$\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4} = 3 \times 10^{5}$

<h3>(C)</h3>

The value of each expression in standard form is

$3 \times 10^{5}=300,000$

Remember that standard form refers to the number without the ten-power.

Jlenok [28]

Step-by-step explanation:

$scale \: factor = \frac{7}{28} = \frac{1}{4} \\$

$ratio \:of \:surface \:areas\\=\frac{2[5\times 7 + 7\times 3+3\times 5]}{2[20\times 28+ 28\times 12+12\times 20] }\\\\=\frac{[35 + 21+15]}{[560+ 336+240] }\\\\=\frac{71}{1136}\\\\=\frac{1}{16}\\\\= 1\: :\: 16$
