Answer:

m=-1

Step-by-step explanation:

2.3-5m=9.8+2.5m

<u>⟹ Multiply both sides by 10:-</u>

<u />2.3\times \:10-5m\times \:10=9.8\times \:10+2.5m\times \:10

23-50m=98+25m

<u>⟹ Subtract 23 from both sides:-</u>

<u />23-50m-23=98+25m-23

-50m=25m+75

<u>⟹ Subtract 25m from both sides:-</u>

<u />-50m-25m=25m+75-25m

-75m=75

<u>⟹ Divide both sides by -72:-</u>

<u />\frac{-75m}{-75}=\frac{75}{-75}

m=-1

Answer:

m=-1

Step-by-step explanation:

2.3-5m=9.8+2.5m

     +5m=9.8+5m

2.3=9.8+7.5m

-9.8   -9.8

-7.5=7.5m

/7.5   /7.5

-1=m

2. Use the following picture for this question:
Art [367]

Answer:

a.  24\sqrt{3}  and 41.6

b.  52.1

Step-by-step explanation:

a.

Considering the left side triangle the blue dotted side is the side "opposite" to the angle given and the side 24 is the side that is "adjacent" to the angle given. The trigonometric ratio tan relates opposite to adjacent. Also, let the blue dotted side be y.

<u>Note:</u> the exact value of tan 60 is \sqrt{3}

Thus, we can write Tan(60)=\frac{y}{24}\\y=24*Tan(60)\\y=24*\sqrt{3} \\y=24\sqrt{3}

Approximate value (rounded to nearest tenth):  24\sqrt{3} =41.6

b.

Considering the triangle to the right, the side "opposite" to the angle given (53 degrees) is 41.6 (just found in part (a)) and the side "hypotenuse" (side opposite to 90 degree angle) is x. The trigonometric ratio sine relates opposite and hypotenuse.

Thus we can write and solve:

Sin(53)=\frac{41.6}{x}\\x=\frac{41.6}{Sin(53)}=52.1

Write two decimals one repeating and one terminating with the values between 0 and 1
weqwewe [10]

A repeating decimal is one that essentially goes on forever. A terminating decimal is one that has an end, therefore a definite value.

The fraction 1/3 is a repeating decimal, because when you divide 1 by 3, you get .333333 (to infinity). To show that something is repeating, draw a bar (or line) above the number that is repeating, in this case, 3.

The fraction 1/4 is a terminating decimal. Like the one above, when you divide 1 by 4, you get a fraction. In this case, it is .25, which does not repeat.

The fractions are there just to show you how you could get to either, but your terminating decimal is .25, and your repeating decimal is .3 (but with a line over the 3 if possible).
