10) The second angle in a triangle is 3° less than twice the first angle. The third angle measure 8° more than
twice the first angle Find each angle.

Answers

Answer:

35, 67 and 78

Step-by-step explanation:

the angles are:

n, 2n-3 and 2n+8

there are 180 degrees in a triangle, so adding those terms together will give us 180

5n + 5 = 180

180 - 5 = 175

5n = 175

175 / 5 = 35

n = 35

now we have n we can put it in to the formula we have for the angles at the start:

n = 35

2n - 3 = 67

2n + 8 = 78

so the angles are

35, 67 and 78

Points D and E are midpoints of the sides of triangle ABC. The perimeter or the triangle is 48 units. What is the value of t?

Answers

Answer:

2 units

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangle are acute, obtuse, scalene, isosceles, equilateral and right angled triangle.

Since point D and E are midpoints of the sides of triangle ABC, hence:

AD = BD = 3t, BE = CE = 4t, AC = 7t + 6

The perimeter of triangle ABC = AC + BC + AB = AC + AD + BD + BE + CE;

Substituting:

48 = 7t + 6 + 3t + 3t + 4t + 4t = 21t + 6

48 = 21t + 6

21t = 42

t = 2 units

What is the sum of (2n – 5m) and (n + m)?

Answers

Answer:

3n - 4m

Step-by-step explanation:

(2n-5m)+(n+m)

so we get this equation and from here, we expand the equation by removing the brackets, you should get:

2n-5m+n+m and just solve from here.

to make it easier, put the like terms together:

2n+n+m-5m

= 3n-4m

Answer:

3n - 4m

Step-by-step explanation:

(2n – 5m) and (n + m) in this case have the same value if the parentheses are removed.  We end up with:

2n – 5m

 n +   m

--------------        Grouping like terms vertically, as shown here, may make this

                         addition a bit easier.

2n – 5m

 n +   m

--------------

 3n - 4m (final answer)

If you put $25 each month into a savings account that paid a simple interest rate of 6.5% each year, how much would you have in your account at the end of two years?

Answers

Answer:

$339.00

Step-by-step explanation:

If you put $25 each month into a savings account that paid a simple interest rate of 6.5% each year, how much would you have in your account at the end of two years?

We solve the above question using the Equation:

A = P(1 + rt)

P = Principal = Amount deposited each month = $25

The amount deposited in a year = $25 × 12 months = 300

Calculation:

First, converting R percent to r a decimal

r = R/100 = 6.5%/100 = 0.065 per year.

Solving our equation:

A = 300(1 + (0.065 × 2)) = 339

A = $339.00

Therefore, you would have $339 in your account after 2 years

1 US Dollar is equal to 100 Bells
How many US Dollars in 186,000 Bells?

**please explain how you solved 100% confused lololol

Answers

Answer:

So basically you have to multiply.

Step-by-step explanation:

If one US Dollar is equal to 100 bells then how many US Dollars would you need to get to 186,000 bells?

Mk Let's use our brains here.

Let's just convert everything to bells real quick. No dollars.

100 bells times what equals 186,000?

100 x ?  = 186,000

That Number is 8600

100 x 8600 = 186,000

So now that we have that number, how many US dollars is equal to 8600?

It's 86!

Because 100(bells) x 86(dollars) = 8600 bells'

So your answer is 86 dollars

Hope this helped!

The length of a rectangle is 4 yd longer than its width.
If the perimeter of the rectangle is 56 yd, find its length and width.

Answers

Answer: The length of the rectangle is 16 yards and the width is 12 yards.

Step-by-step explanation:

The length is 4 yds longer than the width. Let's remove that from the perimeter so that the perimeter will be as if all sides had the same length (remember there are 2 sides for length and 2 sides for width).

[tex]56-4-4\\48[/tex]

Now we made it so that the extra 4 yards are gone and all sides are equal like a square. Now we can divide by 4 to determine the length of each of the now equal sides

[tex]\frac{48}{4} =12[/tex]

So all of the sides are 12, 12, 12, and 12. To two of the sides we can add back the extra 4 yards we took out giving us sides of 12, 12, 16, and 16.

Let's add it all together and see if it makes the perimeter of 56

[tex]12+12+16+16\\24+32\\56[/tex]

It does! Since the length is 4 yds longer than the width the length is 16 and width is 12.

Segments AB and CB are tangent to ⨀T. What is the perimeter of ABCT?

Answers

Answer:

perimeter is 46

Step-by-step explanation:

Sq(BT) = sq(AT) + Sq(AB)

Sq(17) = Sq(8) + Sq(AB)

So AB = 15

So perimeter of ABCT is 15 + 15 + 8 + 8 = 46

Segments AB and CB are tangent by the Pythagoras theorem, So the perimeter of ABCT is 46 units.

What is the perimeter?

The perimeter of any given figure is the sum of the measure of boundaries of that figure.

Segments AB and CB are tangent.

By the Pythagoras theorem,

[tex](BT)^2 = (AT)^2 + (AB)^2\\(17) ^2= (8) ^2+ (AB)^2[/tex]

So AB = 15

So perimeter of ABCT

= 15 + 15 + 8 + 8

= 46
