Answer:

$\frac{200}{2793}$

Step-by-step explanation:

1. Convert the decimal into a fraction by doing this. Take 1.8 and write it above a fraction line without the decimal sign.

2. Count the decimal places and below the fraction line write the multiple of 10 with that many zeros so that would $\frac{18}{10}$

3. Simplify the fraction so that would be $\frac{9}{5}$ .

4. Now in order to divide a fraction, multiply by the reciprocal of that fraction so that would be $\frac{9}{5} *\frac{1000}{25137}$ .

5. Now reduce the number with the gcf (greatest common factor) which would be 5. So now we have 9* $\frac{200}{25137}$

6. Reduce the numbers again using the gcf which now would be 9. Now you have the answer which should $\frac{200}{2793}$

Sofia's parents gave her an allowance for summer camp of $125.if she is going to be at camp for 6 weeks,what is the most she can

professor190 [17]

Sofia can spend at most $20.83 each week.

Step-by-step explanation:

Given,

Amount of given by Sofia's parent = $125

Number of weeks = 6

Let,

x represent the amount that Sofia can spend each week.

As Sofia has $125, therefore, she can spend maximum $125 or less than that.

$6x\leq 125$

Dividing both sides by 6

$\frac{6x}{6}\leq \frac{125}{6}\\x\leq 20.83$

Sofia can spend at most $20.83 each week.

Question 8 Find the unit vector in the direction of (2,-3). Write your answer in component form. Do not approximate any numbers

slamgirl [31]

Answer:

The unit vector in component form is $\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)$ or $\hat{u} = \frac{2}{\sqrt{13}}\,i-\frac{3}{13}\,j$ .

Step-by-step explanation:

Let be $\vec u = (2,-3)$ , its unit vector is determined by following expression:

$\hat {u} = \frac{\vec u}{\|\vec u \|}$

Where $\|\vec u \|$ is the norm of $\vec u$ , which is found by Pythagorean Theorem:

$\|\vec u\|=\sqrt{2^{2}+(-3)^{2}}$

$\|\vec u\| = \sqrt{13}$

Then, the unit vector is:

$\hat{u} = \frac{1}{\sqrt{13}} \cdot (2,-3)$

$\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)$

The unit vector in component form is $\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)$ or $\hat{u} = \frac{2}{\sqrt{13}}\,i-\frac{3}{13}\,j$ .

GCF of 28,42,and 56.<br><br> Please show work

natta225 [31]

<h2>Answer: 14</h2>

Step-by-step explanation:

If we factorize the numbers, we may be able to surmise the GCF:

28 = 2 × 2 × 7

42 = 2 × 3 × 7

56 = 2 × 2 × 2 × 7

∴ the GCF is 2 × 7 = 14
