the number of words Sylvia types varies directly with the amount of time she spends typing. If Sylvia types 100 words in 2.5 min

Eddi Din [679]

Answer:

600 words

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (100, 2.5, 5) as shown below:

$\frac{100}{2.5}=\frac{x}{15}$

Next we cross multiply. We multiply 2.5 and x, and we multiply 100 and 15.

$2.5(x)=2.5x$

$100(15)=1,500$

Now, lets put the values above back into the equation:

$2.5x=1,500$

Our next step is to divide 1,500 by 2.5 to get x by itself.

$x=\frac{1,500}{2.5}$

$x=600$

Sylvia can type 600 words in 15 minutes.

i already have the answers but i need to show my work. ill tell you my insta and please show me a picture of the work :))

Answer:

${( - 6)}^{2} \times {( - 6)}^{5}$

from law of indices:

${a}^{n} \times {a}^{m} = {a}^{(n + m)}$

therefore:

$= ( - 6) {}^{ \{2 + 5 \}} \\ = ( - 6) {}^{7} \\ = { \boxed{ \boxed{ - 279936}}}$

$- 4 {a}^{5} (6 {a}^{5} ) \\ = ( - 4 \times 6)( {a}^{5} \times {a}^{5} ) \\ = - 24 \{{a}^{(5 + 5)} \} \\ = { \boxed{ \boxed{ - 24 {a}^{10} }}}$

$( - 7 {a}^{4} b {c}^{3} )(5a {b}^{4} {c}^{2} ) \\ = ( - 7 \times 5)( {a}^{4} \times a)(b \times {b}^{4}) \times ( {c}^{3} \times {c}^{2} ) \\ = - 35 {a}^{5} {b}^{5 } {c}^{5} \\ = { \boxed{ \boxed{ - 35 {(abc)}^{5} }}}$

$\frac{ {8}^{15} }{ {8}^{13} }$

from law of indices:

$\frac{a {}^{n} }{ {a}^{m} } = {a}^{(n - m) } \\$

therefore:

$= {8}^{(15 - 13)} \\ { \boxed{ \boxed{ {8}^{2} = 64 }}}$

follow the procedure for application to other questions.

Any question, be free to ask. Thank you …

A sphere has a volume of 4500pi cubic inches. find the surface area of the sphere.

MakcuM [25]

$V=\frac{4 \pi r^3}{3}\\
\\
4500\pi=\frac{4 \pi r^3}{3}\\
\\
13500 \pi=4 \pi r^3\\
\\
r^3=\frac{13500 \pi}{4 \pi}\\
\\
r^3=3375 \\
\\
\boxed{r=15 in}$

$S=4 \pi r^2\\
\\
S=4 \pi 15^2\\
\\
\boxed{S=900 \pi \ in^2}$
