$\bf \cfrac{45}{63}\implies \cfrac{9\cdot 5}{9\cdot 7}\implies \cfrac{9}{9}\cdot \cfrac{5}{7}\implies 1\cdot \cfrac{5}{7}\implies \cfrac{5}{7}$

Answer: OPTION A.

Step-by-step explanation:

You have the folllowing fraction given in the problem:

$\frac{5}{7}$

To find an equal fraction, you must multiply the numerator and the denominator by the same number.

OPTION A. The product is obtained by multiplyin 5 by 9 and the produc 63 is obtained by multiplyin 7 by 9. Then, you obtain:

$\frac{5*9}{7*9}$ = $\frac{45}{63}$

The fraction of OPTION B is not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

The fraction of OPTION C is not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

The fraction of OPTION D is not not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

Write a decimal subtraction problem that requires regrouping to solve. then solve the problem

Svetach [21]

For example, think about 8.4 - 2.9.

You have to regroup because you can't subract 4 - 9.
4 turns into a 14 since you borrow from the left number, 8.
8 turns into a 7 after that.
Now, you have to subtract 14 - 9 and 7 - 2. You're answer is 5.5.
You can check your work by doing inverse opperations:
By adding:
5.5 + 2.9 = 8.4
Or by subracting 8.4 - 5.5 = 2.9

Hope this helped you! If you need a better explaination or another example, I will be happy to help you! :)

Given the information in the picture, which trigonometric identity can be used to solve for the height of the blue ladder that i

Stells [14]

The trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is $\rm sin=\dfrac{o}{h}$ .

We have to determine

Which trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building?.

<h3>Trigonometric identity</h3>

Trigonometric Identities are the equalities that involve trigonometry functions and hold true for all the values of variables given in the equation.

Trig ratios help us calculate side lengths and interior angles of right triangles:

The trigonometric identity that can be used to solve for the height of the blue ladder is;

$\rm Sin47=\dfrac{50}{H}\\\\H=\dfrac{50}{sin47}\\\\H=68 feet$

Hence, the trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is $\rm sin=\dfrac{o}{h}$ .
