Find the values of x and y. lines that appear to be tangent are tangent
Ket [755]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value of  y  =  122^o

The value of  x = 61^o

Step-by-step explanation:

Generally the total angle that make up a circle is

      \theta _T = 360

From the diagram we see that

    \theta _T  =  y^o + 238^o

=>    y^o  =  360  -238

       y^o  =  122^o

Generally angle that is formed as a result of interception of a chord and a tangent is equal to the intercepted arc divided by 2

 This implies that

           x =  \frac{y}{2}

substituting values

          x =  \frac{122}{2}

          x = 61^o

5(3a-1)-2(3a-2)=3(a+2)+v
STatiana [176]

Answer:

<u>The answer is option C. 6a-7</u>

Step-by-step explanation:

Given that

5(3a-1)-2(3a-2)=3(a+2)+v

Solve for v

∴ v = 5(3a-1)-2(3a-2) - 3(a+2)

∴ v = 15a - 5 - 6a + 4 - 3a - 6

∴ v = 15a - 6a - 3a - 5 + 4 - 6

∴ v = 6a - 7

<u>So the answer is option C. 6a-7</u>

Suppose you invested $10,000 part at 6% annual interest and the rest at 9% annual interest. If you received $684 in interest aft
victus00 [196]
Assuming simple interest (i.e. no compounding within first year), then
At 6%, interest = 10000*0.06=$600
At 9% interest = 10000*0.09 = $900

Two ways to find the ratio
method A. let x=proportion at 6%
then
600x+900(1-x)=684
Expand and solve
300x=900-684=216
x=216/300=0.72 or 72%
So 10000*0.72=7200 were invested at 6%
10000-7200=2800 were invested at 9%

method B: by proportions
Ratio of investments at 6% and 9%
= 900-684 : 684-600
=216 : 84
= 18 : 7
Amount invested at 6% = 18/(18+7) * 10000 = 0.72*10000 = 7200
Amount invested at 8% = 7/(18+7)*10000=0.28*10000=2800

10. Daniels goes to the shopping center. He has a bank account with a
Savatey [412]

Answer:

-$36

Step-by-step explanation:

Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.

He spent $45 + $150 + $100, adding to a grad total of $295.

To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.
