I need to know the improper fractions answers for:

zmey [24]

Answer:

Part 1) $x=\frac{15}{2}\ units$

Part 2) $z=\frac{15\sqrt{3}}{2}\ units$

Part 3) $y= \frac{15\sqrt{3}}{4}\ units$

Part 4) $b= \frac{45}{4}\ units$

Step-by-step explanation:

step 1

Find the value of x

In the large right triangle

$cos(60^o)=\frac{x}{15}$ ----> by CAH (adjacent side divided by the hypotenuse)

Remember that

$cos(60^o)=\frac{1}{2}$

substitute

$\frac{1}{2}=\frac{x}{15}$

solve for x

$x=\frac{15}{2}\ units$ ---> improper fraction

step 2

Find the value of z

In the large right triangle

Applying the Pythagorean Theorem

$15^2=x^2+z^2$

substitute the value of x

$15^2=(\frac{15}{2})^2+z^2$

solve for z

$z^2=15^2-(\frac{15}{2})^2$

$z^2=225-\frac{225}{4}$

$z^2=\frac{675}{4}$

$z=\frac{\sqrt{675}}{2}\ units$

simplify

$z=\frac{15\sqrt{3}}{2}\ units$

step 3

Find the value of y

In the right triangle of the right

$sin(30^o)=\frac{y}{z}$ ---> by SOH (opposite side divided by the hypotenuse)

substitute the given values of y and z

Remember that

$sin(30^o)=\frac{1}{2}$

so

$\frac{1}{2}=y:\frac{15\sqrt{3}}{2}$

solve for y

$\frac{1}{2}= \frac{2y}{15\sqrt{3}}$

$y= \frac{15\sqrt{3}}{4}\ units$

step 4

Find the value of b

In the right triangle of the right

$cos(30^o)=\frac{b}{z}$ ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values of y and z

Remember that

$cos(30^o)=\frac{\sqrt{3}}{2}$

so

$\frac{\sqrt{3}}{2}=b:\frac{15\sqrt{3}}{2}$

solve for y

$\frac{\sqrt{3}}{2}= \frac{2b}{15\sqrt{3}}$

$b= \frac{45}{4}\ units$

Lindsay earn $7.65 per hour.Her boss has promised her a 7% raise next month. If she works 40 hour per week, how much will she ea

zzz [600]

Answer:

She would make $327.60 each week after the raise

Step-by-step explanation:

First we need to find how much she will make per hour. We can do this by multiplying the per hour rate by the percentage of the raise.

$7.65 * 7% = $0.54

Now we add this amount to the previous hourly rate.

$7.65 + $0.54 = $8.19

Now that we have the new hourly rate, we multiply it by the number of hours that she works.

$8.19 * 40 = $327.60

Frodo ran 2 1/5 miles in 7/12 of an hour. How many miles can Frodo run in one hour?

iVinArrow [24]

Answer:

$\frac{132}{35}$

Step-by-step explanation:

In $\frac{7}{12}$ of an hour, Frodo ran $2\frac{1}{5}$ miles

= $\frac{11}{5}$

So,

Multiplying both sides by $\frac{12}{7}$ , we get,

In $\frac{7}{12}*\frac{12}{7}$ hour, Frodo ran $\frac{11}{5}*\frac{12}{7}$

= $\frac{132}{35}$ miles
