Answer: 22/2, 88/8, and 7062000/642000

Explanation: Notice that the ratio in this problem is written with a fraction bar, so we can find equal ratios in the same way that we find <em>equivalent fractions</em>. In other words, we can simply multiply both the numerator and denominator of 11/1 by the same number.

For example, we can multiply both the numerator and denominator of 11/1 by 2 to get the equal ratio 22/2.

We can also multiply both the numerator and denominator of 11/1 by 8 to get the equal ratio 88/8.

We could also multiply the numerator and denominator of 11/1 by 642,000 to get the equal ratio 7062000/642000.

So the ratio 11/1 is equal to 22/2, 88/8, and 7062000/642000.

Step-by-step explanation:

b. Molly make mistake when he/she divide all equation by 4 but left the 8x remain 8x, it should be 2x.

Mark make mistake in changing the sign whitout changing side/ passing trough equal sign. FYI, + can be - and also - can be + if they move to the other side

i.e.

2 + 3 = 5

2 = 5 - 3

What is the best approximation of the value of w? 1. 4 cm 4. 0 cm 6. 0 cm 7. 3 cm.

MrRissso [65]

To solve the problem we must know about Sine Rule.

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

$\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}$

where

Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.

The value of w is 4.0 cm.

Given to us

VW = 3.3 cm,
∠U = 31°,
∠W = 39°,

<h3>Using the sine law,</h3>

$\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}$

Substitute the values,

$\dfrac{Sin\ W}{w} = \dfrac{Sin\ U}{VW}$

$\dfrac{Sin\ 39^o}{w}=\dfrac{Sin\ 31^o}{3.3}$

$w=\dfrac{(Sin\ 39^o) \times 3.3}{Sin\ 31^o}$

w = 4.03224 cm ≈ 4.0 cm

Hence, the value of w is 4.0 cm.

You can afford a $950 per month mortgage payment. You've found a 30 year loan at 7% interest. a) How big of a loan can you affor

Lubov Fominskaja [6]

Based on the amount to be paid per month, the size of the loan you can afford is $142,792.19.

The total amount you pay to the loan company is $342,000.

The interest on the money is $199,207.81.

The size of the loan is the present value associated with that loan payment that you can afford:

950 = (7/12% x Present value) / ( 1 - (1 + 7/12%)⁻⁽³⁰ ˣ ¹²⁾

950 = (7/12% x Present value) / 0.8767

Present value = $142,792.19

The total amount of money paid is:

= Number of periods x Payment per period

= 30 years x 12 months per year x 950

= $342,000

The interest is:

= 342,000 - 142,792.19

= $199,207.81.
