I want to say answer (A)is the correct answer

It is A.
The HL theorem works when the hypotenuses of two triangles, and another leg, are the same.
For these two triangles the hypotenuses are clearly the same, so we need to know if they have two corresponding equal legs. OM and ON are two corresponding legs, and if these are equal the HL theorem will work. So, the answer is A.

Answer:

see below for a graph

Step-by-step explanation:

You know the line crosses the x-axis at x=6, so one way to write the equation is by translating the line with slope -1/2 to a point 6 units to the right of the origin.

y = -1/2(x -6)

A circular cake is 360 degrees if you eat a piece that is 40 degrees of the cake, how many degrees are left in the cake?

ololo11 [35]

Step-by-step explanation:

a whole circle is 360°.

if you take away 40°, how many are left ?

that is absolutely the same as the question, when I have 15 apples and 6 are eaten, how many are left ?

well, 15-6 = 9 apples are left.

and so, 360-40 = 320° are left.

You split $1500 between two savings accounts one pays 4%interest and the other pays 5% after one year you have earned $69.50 in

ANTONII [103]

Answer:

Step-by-step explanation:

Use the basic simple interest formula:

P * r * t = I and put the info into a table with those variables along the top, formig the columns we need:

P * r * t = I

Acct 1

Acct 2

If we have a total of 1500 to split up between 2 accounts, we put x amount of money into one and then have 1500-x left to put into the other. We will fill those in along with the interest rates in decimal form and the time of 1 year:

P * r * t = I

Acct 1 x .04 1

Acct 2 1500-x .05 1

Looking at the formula we are told that Prt = I, so we will multiply P times r times t and fill in the I column:

P * r * t - I

Acct 1 x .04 1 .04x

Acct 2 1500-x .05 1 .05(1500-x)

The total Interest earned by the addition of the interest earned from both accounts is 69.50. So we add the interest column together and set it equal to 69.50:

.04x + .05(1500 - x) = 69.50 and

.04x + 75 - .05x = 69.50 and

-.01x = -5.5 so

x = 550

That's how much money is in the account earning 4% interest.

The product of two consecutive positive odd numbers is 195.By constructing a quadratic equation and solving it, find the two num

Tomtit [17]

Step-by-step explanation:

x = one odd number

the second odd number is (x+2), as both are consecutive.

so,

x × (x + 2) = 195

x² + 2x = 195

x² + 2x - 195 = 0

the formula to solve this is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 2

c = -195

x = (-2 ± sqrt(4 - 4×1×-195))/(2×1) =

= (-2 ± sqrt(4 + 4×195))/2 = (-2 ± sqrt(784))/2 =

= (-2 ± 28)/2 = -1 ± 14

x1 = -1 + 14 = 13

x2 = -1 - 14 = -15 which is invalid as the numbers are positive.

so, the two numbers are 13 and 15.
