Answer:
right triangle
Step-by-step explanation:
A Right triangle is a triangle that has one of its angle as 90°.
Since the triangular shaped tiles has a right angle, the kind of triangle Kevin found will be a right triangle.
A right triangle has two acute angles (angles less than 90°) and a right angle
If "k" is a negative number, then k + 2 is a negative number.
Answer:
Not exactly, if a possitive and a negetive are added together the number that was larger will choose its symbol. Say "k" is -3, so -3 + 2 = -1, or if "k" was -1, then -1 + 2 = 1.

Answer:
2(6a+5)
Step-by-step explanation:
In ABC, the interior angle at A is 51° and the exterior angle at B is 119º. The interior angle at C measures
A 51°
B 68°
C 90°
D 39°
Answer:
68 degrees
Step-by-step explanation:
To get the interior angle, we use an important triangle principle
The principle is that the sum of the opposite interior angles equal the exterior angle
Let the second interior angle be x
x + 51 = 119
x = 119-51
x = 68

The parallelogram shown below has an area of 21 units?.
7
b
8
Find the missing base.
b=
units
Answer:
The missing base b is 3 units
Step-by-step explanation:
The parallelogram has two different bases, b1 and b2Each base has a height perpendicular to it from the base parallel to ith1 is the height of b1 and h2 is the height of b2The formula of the area of the parallelogram is A = b1 × h1 = b2 × h2Let us solve the problem
In the given figure
∵ The given figure is a parallelogram
∵ The line of length 7 is perpendicular to the base that parallels to base b
∵ The base b has a height of 7 units
→ By using the formula of the area above
∵ A = b1 × h1
∵ b1 = b and h1 = 7 units
∵ The parallelogram has an area of 21 square units
∴ A = 21
→ Substitute the value of A and h in the rule of the area
∵ 21 = b × 7
∴ 21 = 7b
→ Divide both sides by 7
∴ 3 = b
∴ The missing base b is 3 units
determnine if each table shown below represents a function or not.
Answer:
Table 1 does not represent a function.
Table 2 does not represent a function.
Step-by-step explanation:
Table 1
Input (x) 1 3 5 5 9
Output (y) 7 16 19 20 28
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Table 1 indicates that x = 5 is repeated twice. In other words, the input x = 5 is duplicated and we know that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, table 1 does not represent a function.
Table 2
Input (x) 0.5 7 7 12 15
Output (y) 1 15 10 23 30
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Table 2 indicates that x = 7 is repeated twice. In other words, the input x = 7 is duplicated and we know that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, table 2 does not represent a function.
Conclusion:
We have concluded that both tables do not represent the function.

In fixed deposit, a bank gives 10% interest compounded annually for senior citizens. How many complete years will it take for a sum of money to be more than double.
Answer: 8 years
Step-by-step explanation:
You can find this out use the Rule of 72. By dividing 72 by the fixed interest rate, you can estimate the amount of time it will take for an investment to double in size:
= 72/10
= 7.2 years
= 8 complete years
Example:
Assume they invested $1,000. Interest rate is 10%.
Amount after 8 years will be:
= 1,000 * (1 + 10%)⁸
=$2,143.59
Investment is now more than double.

Round answers to three decimal places. Area of 1st rectangle =0.022 Area of 2nd rectangle = Area of 3rd rectangle = Area of 4th rectangle = Area of 5th rectangle = Area of 6th rectangle = Total area =
Answer:
Total area ≈ 0.082
Step-by-step explanation:
Round answers to three decimal places.
Area of 1st rectangle = 0.032
Area of 2nd rectangle =25 x 0.000863
= 0.022
Area of 3rd rectangle = 0.014
Area of 4th rectangle = 0.008
Area of 5th rectangle = 0.004
Area of 6th rectangle = 0.002
Total area = 0.082
Rounding up to 3 decimal places: this means 3 numbers after the decimal point
Area of 1st rectangle ≈ 0.032
Area of 2nd rectangle ≈ 0.022
Area of 3rd rectangle ≈ 0.014
Area of 4th rectangle ≈ 0.008
Area of 5th rectangle ≈ 0.004
Area of 6th rectangle ≈ 0.002
Total area = 0.032 + 0.022 + 0.014 + 0.008 + 0.004 + 0.002
= 0.082
Total area ≈ 0.082
Answer:
Round answers to three decimal places.
Area of 1st rectangle =0.022
Area of 2nd rectangle =
⇒ 0.014
Area of 3rd rectangle =
⇒ 0.008
Area of 4th rectangle =
⇒ 0.004
Area of 5th rectangle =
⇒ 0.002
Area of 6th rectangle =
⇒ 0.001
Total area =
⇒ 0.051

Step-by-step explanation:
Both widths are the same in a rectangle. So both are 6.5. Then you subtract 13 from 34. Now you are left with 21. No divide that by two to get your two lengths. That is l. L=10.5
Answer:
Step-by-step explanation:
P=2L+2W
P=34 W= 6.5
34=2L+2*6.5
34=2L+13
2L=21
L=10.5
or
Given:
P = 34 [Perimeter]
W = 6.5 {let's use W and L to make it easy to read]
Also known:
P = W + L + W + L = 2(W+L)
Fill in values:
34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]
. . .
17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]
. . .
10.5 = L [NOTE: This is the solution (the value of L)]

help me pleasee i dont know how to do thiss
Step-by-step explanation:
Since UV bisects TW, TW also bisects UV.
=> Line segments UV and TW bisect each other.
=> 4y - 3 = 2y + 1 and 3x + 8 = 3y + 2
=> 2y = 4 and 3x = 3y - 6
=> y = 2 and x = y - 2
=> y = 2 and x = (2) - 2
=> y = 2 and x = 0.
Answer:
y= 181/7 or 25.86
i really dont know about x
The number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees. Which expression represents how many trees will be left in 10 years.
Given:
Present number of trees = 2.5 billions
Rate of decrease = 0.5% per month
To find:
The expression that represents how many trees will be left in 10 years?
Solution:
Exponential decay model:
[tex]P(t)=a(1-r)^t[/tex] ...(i)
where, a is initial value, r is decreasing rate and t is time period.
We have,
a = 2.5 billions
r = 0.5% = 0.005 per month
t = 10 years = 120 months [1 year = 12 months]
Putting a=2.5, r=0.005 and t=120 in (i), we get
[tex]P(120)=2.5(1-0.005)^{120}[/tex]
[tex]P(120)=2.5(0.995)^{120}[/tex]
[tex]P(120)=1.3699657[/tex]
[tex]P(120)\approx 1.37[/tex]
Therefore, the required expression is [tex]2.5(1-0.005)^{120}[/tex] and the remaining trees after 10 years is about 1.37 billions.
Kelly typed a 36 word paragraph is 2/3 minute what is his typing speed in words per minute?
Answer:
His typing speed is 24 wpm. (Words Per Minute).
Step-by-step explanation:
The first thing you would have to do is convert 2/3 into a decimal, so 2/3 converted into a decimal is 0.66666666666667, then you would take that number, and multiply that by 36, the you would get you answer of 24. So, Kelly's typing speed is 24 wpm. (words per minute).
