Wha rid the value of n very confused and need help

Mathematics
1 answer:
Slav-nsk [51]2 years ago
7 0

Answer:

n = 6

Step-by-step explanation:

Two intersecting chords. The product of the parts of one chord is equal to the product of the parts of the other chord, that is

7(n + 4) = 5(n + 8) ← distribute parenthesis on both sides

7n + 28 = 5n + 40 ( subtract 5n from both sides )

2n + 28 = 40 ( subtract 28 from both sides )

2n = 12 ( divide both sides by 2 )

n = 6

Victoria bought a jacket in the sale which had 20% off. If it cost ?36 on sale what did it cost before the sale?
Basile [38]

Answer:

The jacket costs $45

Step-by-step explanation:

In order to find this, notice that the price of the sale represents 80% of the total cost. This is because we took 20% away with the sale. Now we can find the overall amount by dividing the sale cost by the amount it represents.

$36 / 80% = $45

The functions f(x) and g(x) are shown.
erastova [34]

The function f(x) takes on the value 2 when x =  -7 and x = -3, and thus the corresponding points are (-7,2) and (-3,2).

The points where g(x) = 0 are called "roots" or "solutions," and is (3,0).

f(x) > g(x)  on the approx. interval (-9, -3/4).

Find the slope of the line that passes through (5, 5) and (1, 0),
Ludmilka [50]

Answer:

Slope is 5/4.

Step-by-step explanation:

The slope of two points can be expressed as \displaystyle \large{m=\frac{y_2-y_1}{x_2-x_1} where m represents the slope,

Let (5,5) be (x1,y1) and (1,0) be (x2,y2). Thus:

\displaystyle \large{m=\frac{0-5}{1-5}=\frac{-5}{-4}=\frac{5}{4}}

You can also consider both points other way around. We can let (1,0) be (x1,y1) and (5,5) be (x2,y2) and therefore:

\displaystyle \large{m=\frac{5-0}{5-1}=\frac{5}{4}}

Therefore, the slope is 5/4.

Bonnie deposits $70.00 into a new savings account. *The account earns 4.5% simple interest per year. * No money is added or remo
Angelina_Jolie [31]

Answer with Step-by-step explanation:

Amount in Bonnie's account initially=$ 70

The formula for simple interest= \dfrac{P\times R\times T}{100}

Where P is the principal amount

R is rate of interest

and T is the time

Here, P=70,R=4.5,T=3

Interest=  \dfrac{70\times 4.5\times 3}{100}

           = $ 9.45

Hence, Total amount in his savings account after 3 years= $(70+9.45)

                                                                                              = $ 79.45

Hence, correct option is:

B. $ 79.45
