Answer:

<u><em>1. x = 8, y =138</em></u>

<u><em>2. x = 110</em></u>

Step-by-step explanation:

First we will need to find the value of x.

Since, I feel like being a kindergartener I'll do it the long way.

(5*2+2)+(6*2)

12+12

24

That wouldn't work

(5*8+2)=(6*8)

42+48=90

Therefore <em><u>x = 8</u></em>

Since we know 42 would be 42 degrees and it is a straight angle for both 5x+2 and y.

We would subtract 180-42=138.

Therefore, <em><u>y = 138</u></em>

2 would be simple. All we need to do is add 80+30=110 then subtract it by 180

180-110=70. Since x and the 70 degrees equal 180 degrees.

180-70=110

Therefore, your answer would be <em><u>x= 110</u></em>

Step-by-step explanation:

Turn your fractions into improper and make them have the same denominator

\frac{95}{10}+\frac{46}{10}=\frac{141}{10}

Leave it as is or simplify to 14 \frac{1}{10}

You start a search for a buried object by marking the center of a field as (0, 0), with coordinates giving distances in yards. C
pychu [463]

The coordinates to the second spot can be represented by the coordinates

(-12 + 3, 8 -11)

Since we are going 3 yards to the east we would be affecting the x-axis and since we are going east we will need to add 3 yards the x axis of the first spot


11 yards south would be affecting the y- axis negatively. We would need to subtract 11 from the y- axis of the first spot.

the coordinates of the second spot would be

-12 +3 = -9

8 -11 = -3


(-9, -3)

7. A man makes a simple discount note for $6,200, at an ordinary bank discount rate of 8.84%, for 40 days. What is the effective
Elina [12.6K]

Answer:

The effective interest rate, rounded to the nearest tenth, is 0.1%.

Step-by-step explanation:

The banker's rule is the simple interest formula.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly) and t is the time, in years.

The effective interest rate is given by the following formula:

E_{IR} = \frac{E}{P}.

In this problem, we have that:

A man makes a simple discount note for $6,200, at an ordinary bank discount rate of 8.84%, for 40 days. We consider that the year has 360 days. This means that P = 6200, I = 0.0884, t = \frac{40}{360} = \frac{1}{9}.

So

E = 6200*0.0884*\frac{1}{9} = 60.9

The effective interest rate is

E_{IR} = \frac{E}{P} = \frac{60.9}{6200} = 0.0098 = 0.001

The effective interest rate, rounded to the nearest tenth, is 0.1%.
