Answer:

c. The mean is the same as the average. The average is (6 * 5 + 7 * 4 + 8 * 7 + 9 * 10 + 10 * 4) / (5 + 4 + 7 + 10 + 4) = 244 / 30 = 8.133.

Sandra has a cylindrical mold for making candles with a radius of 3.4 cm and a height of 6 cm. If Sandra uses a rectangular bloc

Wittaler [7]

Answer:

$14\ candles$

Step-by-step explanation:

step 1

Find the volume of the cylindrical mold

The volume is equal to

$V=\pi r^{2} h$

we have

$r=3.4\ cm$

$h=6\ cm$

assume

$\pi=3.14$

substitute

$V=(3.14)(3.4)^{2}(6)$

$V=217.79\ cm^{3}$

step 2

Find the volume of the wax

The volume is equal to

$V=(15)(12)(18)$

$V=3,240\ cm^{3}$

step 3

Divide the volume of the wax by the volume of the cylindrical mold, to calculate the number of candles

$3,240/217.79=14.9\ candles$

Round down

$14\ candles$

What is an equation of the line perpendicular to y=-x-2 and through (-2, 4)?

Salsk061 [2.6K]

Answer: y = x + 6

Step-by-step explanation:

$\mathrm{Find\:the\:line\:}\mathbf{y=mx+b}\mathrm{\:perpendicular\:to\:}y=-x-2\mathrm{\:that\:passes\:through\:}\left(-2,\:4\right)$

$\mathrm{For\:a\:line\:equation\:for\:the\:form\:of\:}\mathbf{y=mx+b}\mathrm{,\:the\:slope\:is\:}\mathbf{m}$

$m=-1$

$\mathrm{The\:perpendicular\:slope\:is\:the\:negative\:reciprocal\:of\:the\:given\:slope}$

$\left(-1\right)m_p=-1$

$\frac{\left(-1\right)m_p}{-1}=\frac{-1}{-1}$

$m_p=1$

$\mathrm{Compute\:the\:line\:equation\:}\mathbf{y=mx+b}\mathrm{\:for\:slope\:m=}1\mathrm{\:and\:passing\:through\:}\left(-2,\:4\right)$ $\mathrm{Plug\:the\:slope\:}1\mathrm{\:into\:}y=mx+b$

$y=x+b$

$\mathrm{Plug\:in\:}\left(-2,\:4\right)\mathrm{:\:}\quad \:x=-2,\:y=4$

$4=\left(-2\right)+b$

$-2+b=4$

$\mathrm{Add\:}2\mathrm{\:to\:both\:sides}$

$-2+b+2=4+2$

$\text{Simplify}$

$b=6$

$\mathrm{Construct\:the\:line\:equation\:}\mathbf{y=mx+b}\mathrm{\:where\:}\mathbf{m}=1\mathrm{\:and\:}\mathbf{b}=6$

$y=x+6$

5 1/6 divided by 7/10<br> (simplify and make a fraction)

True [87]

Answer:

$\frac{155}{21}$

Step-by-step explanation:

$5\frac{1}{6} = \frac{31}{6}$
Re-write the expression: $\frac{31}{6}$ ÷ $\frac{7}{10}$
31/6 ÷ 7/10 = 31/6 × 10/7
$\frac{31}{6}$ × $\frac{10}{7} = \frac{310}{42}$
310/42 = 155/21

I hope this helps!
