Answer:

a- p=18// b- b=-7

Step-by-step explanation:

a- 25-7 to isolate the p is 18

b- -20= (2n-6)//add 6 to isolate the n by itself// -14=2n//divide by 2 to simplify//n=-7

Angle O=64

Side m=7.3159882(rounded if needed)

Side n=16.68902(round if needed)

We are given

Angle M which equal 26.

Angle N equals 90 degrees

Side MN which equal 15.

We are asked to find all the missing elements of the triangle.

Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.

$90 + 26 + x = 180$

$116 + x = 180$

$x = 64$

Angle O=64 degrees

We can find side m by doing law of sines.

$\frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) }$

$\frac{on}{ \sin(26) } = \frac{15}{ \sin(64) }$

$on = \frac{15}{ \sin(64) } \times \sin(26)$

which is 7.315(round if neeeded).

We can find side n using pythagorean theorem,

${15}^{2} + {7.3}^{2} = {n}^{2}$

$225 + 53.29 = {n}^{2}$

$\sqrt{278.29}$

Side n=16.689(round if needed)

Janet and her brother John went out to eat. Both paid the same amount. Janet got three burgers and left a $10 tip. John bought 4

lianna [129]

Answer:

Cost for 1 burger = 5 $

Amount spent by Janet = 25$

Amount spent by John = 25$

Explanation:

Let the cost for burger be p.

Janet got three burgers and left a $10 tip

Amount spent by Janet = 3 p + 10

John bought 4 burgers, but only left a $5 tip

Amount spent by John = 4 p + 5

Both paid the same amount.

So, we have 3 p + 10 = 4 p + 5

=> p = 5 $

So, cost for 1 burger = 5 $

Amount spent by Janet = 3 x 5 + 10 = 25$

Amount spent by John = 4 x 5 + 5 = 25$

Assume the rate of inflation is 8% per year for the next 2 years. What will be the cost of goods 2 years from now, adjusted fo

Paha777 [63]

<h3>Answer: $326.59</h3>

==============================================

Work Shown:

F = future value

P = present value = 280

r = rate of inflation in decimal form = 0.08

t = elapsed time in years = 2

---------

F = P*(1+r)^t

F = 280*(1+0.08)^2

F = 326.592

F = 326.59

BRAINLIEST TO FIRST CORRECT ANSWER!!

sineoko [7]

Answer:

$57\:\mathrm{km}$

Step-by-step explanation:

Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

Let $x$ represent how much farther his truck can go, in kilometers:

$\frac{2}{76}=\frac{1.5}{x}$

Cross-multiplying, we get:

$2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}$
