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

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.
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

At the neighborhood playground, your friend sits on a swing and gets pulled back by you to the highest point that you can reach. When you let go, your friend rides the swing without receiving or providing additional push. Your friend travels along an arc of 14 feet on the first swing (back to front). As the swing comes backwards, the length of the arc is .80 of the previous swing. This continues: each successive arc created by swinging is .80 of the previous swing.
a. Find the length of the arc for the 5th swing (the 5th arc). Round to the thousandths place.
b. On which swing is the length of the arc first less than 1 foot?
c. Find the total distance your friend travels in all of the swings up to and including the swing in answer to letter b.

What is the sum of (2n – 5m) and (n + m)?
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?
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
I didn’t mean to click C but yea I need help
Answer:
C.
Step-by-step explanation:
It says from least to greatest. You start off looking at the whole numbers and 1 is the least. Your going to start at 1 2/5 (that rules off A and B). The next number you need to compare is 3/10 and 5/8. Since 5/8 is bigger than 3/10 the answer would be C.

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.
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.

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?
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
Joseph claims that a scatterplot in which the y-values increase as the x-values increase must have a linear association. Amy claims that the scatterplot could have a nonlinear association. Which statement about their claims is true?
Joseph is correct because only a line will increase along the whole data set. The scatterplot will have a positive, linear association.
Joseph is correct because only a line will decrease along the whole data set. The scatterplot will have a negative, linear association.
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
Amy is correct because only a nonlinear association could increase along the whole data set. A line has the same slope at any point, but a curve can get steeper at different points.
Answer: Choice C
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
======================================================
Explanation:
Just because the data points trend upward (as you go from left to right), it does not mean the data is linearly associated.
Consider a parabola that goes uphill, or an exponential curve that does the same. Both are nonlinear. If we have points close to or on these nonlinear curves, then we consider the scatterplot to have nonlinear association.
Also, you could have points randomly scattered about that don't fit either of those two functions, or any elementary math function your teacher has discussed so far, and yet the points could trend upward. If the points are not close to the same straight line, then we don't have linear association.
-----------------
In short, if the points all fall on the same line or close to it, then we have linear association. Otherwise, we have nonlinear association of some kind.
Joseph's claim that an increasing trend is not enough evidence to conclude the scatterplot is linear or not.
