Answer:

98 degrees

Step-by-step explanation:

Since angle LON is a straight angle, that means its measure is 180 degrees. So, the two angles that make up angle LON add up to 180. You can create the following equation:

(3x + 89) + (8x + 58) = 180

Then, add like terms.

3x + 8x = 11x

89 + 58 = 147

11x + 147 = 180

Subtract 147 from both sides.

11x = 180 - 147

Add like terms.

11x = 33

Now, divide by 11 on both sides.

x = 3

Since we now have the value of x, we can plug it into the equation to find angle MON:

MON = 3x + 89

Substitute 3 for x

MON = 3(3) + 89

MON = 9 + 89

MON = 98

Find 35% of 65, since A= 35 and B= 65.  

35%=.35  

Multiply that by 65, for the percentage.

65*.35= 22.75

So, 35% of 65= 22.75

22.75 is not equal to 35.

This statement is false.

Answer:

20

Step-by-step explanation:

We will start by writing the following ratio

miles:gas

1200:60

This means that we have

x:1

divide 1200 by 60 to get x

I get

x=20

Answer:

20 miles per gallon.

Step-by-step explanation:

You have to divide 1,200 by 60. Then you will be left with 20 miles/gallon

Answer:

$18.97

Step-by-step explanation:

Add $7.49, $8.29, and $1.79 together= $17.57.

Then, add the 8% tax. So $17.57+8% of tax= $18.97.

Answer:

1,680

Step-by-step explanation:

We know a hummingbird beats its wings 420 times in 30 seconds. To find the unit rate, divide 420 by 30.

420/30

42/3

14 beats/second

Now we know a hummingbird beats its wings 14 times in 1 second. Two minutes equals 120 seconds. Multiply 14 by 120 to get the answer here.

14 * 120

(14 * 12) * 10

168 * 10

1,680 beats

Answer:

1680

Step-by-step explanation:

From the table, we can see that per each 30 seconds, a mocking bird flaps its wings 420 times.

Each minute contains 60 seconds. Therefore, in order to calculate the number of times a mockingbird flaps its wings in 2 minutes, we can

60 seconds x 2 minutes = 120

Then, we can divide this number by 30 to figure out how many times we need to multiply 420 to get our answer.

120/30 = 4

Therefore,

420 x 4 = 1680

Answer:

Answer:

[tex]k=\dfrac{l(h-1)}{2h}[/tex]

Step-by-step explanation:

The given equation is :

[tex]h=\dfrac{l}{l-2k}[/tex] ....(1)

We need to find the value of k.

Cross multiplying equation (1)

[tex]h(l-2k)=l\\\\hl-2hk=l\\\\hl-l=2hk\\\\k=\dfrac{l(h-1)}{2h}[/tex]

So, the value of k is equal to [tex]\dfrac{l(h-1)}{2h}[/tex].

There are missing details, which is why its solution is as follows:

When an angle bisector points so, its two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions. In such a single point, calling its incentives, follow three-angle engineers are required of its three triangle angles.

Answer:

UNLIKELY

Step-by-step explanation:

Given that:

Probability of rolling a six with a six sided nuner cube = 1/6

Required outcome / Total possible outcomes

Number of 6 / total sides of number cube = 1/6

The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.

Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'
