Area of a triangle = 12bh
Area =
Perimeter (rounded to the nearest tenth) =
Answer:
area = 14 square unitsperimeter = 19.1 unitsStep-by-step explanation:
The base of the triangle extends from x=2 to x=6, a distance of 4 units.
The height of the triangle is 9 - 2 = 7 units.
Then the area is ...
A = (1/2)(4 units)(7 units) = 14 units^2

Find the coordinate of the midpoint of a segment with the endpoints (5,11) and (3,1)
Answer:
(1,5)
Step-by-step explanation:
You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]
So, the Change In X is: 5 - 3= 2
And the Change in Y is: 11 - 1 = 10
Once you divide both of the changes by 2, you get
X: 1
Y: 5
So the midpoint is: (1,5)

The expression i/pt represents the rate of instrest being charged if a loan of p dollars for t years required i dollars in intrest to be paid find the intrest rate if a $690 loan for 3 years to buy a used personal computer requiers $151.11 in intrest to be paid
Answer:
7.3%
Step-by-step explanation:
Given:
Formula for Rate of interest [tex]R[/tex]:
[tex]R=\dfrac{i}{Pt}[/tex]
Where [tex]i[/tex] is the rate of interest.
[tex]P[/tex] dollars is the loan and
[tex]t[/tex] years is the time for which interest is to be paid
[tex]P =\$690\\t=3\ years\\i=\$151.11[/tex]
To find:
[tex]R=?[/tex]
Solution:
Putting the given values in the formula:
[tex]R=\dfrac{151.11}{690 \times 3}\\\Rightarrow R=\dfrac{151.11}{2070}\\\Rightarrow R=0.073[/tex]
Multiply the above value with 100 to find the percentage.
i.e.
[tex]R=0.073\times 100 = \bold{7.3\%}[/tex]
Therefore, the answer is 7.3%

What is the 7th term of the geometric sequence?
2, 8, 32, 128, ...
To find the 7th term of the geometric sequence 2, 8, 32, 128, ..., we must first determine the common ratio between consecutive terms.
The common ratio, denoted by 'r', is found by dividing any term by its preceding term. In this case, dividing 8 by 2 gives us a common ratio of 4. Now that we know the common ratio, we can use the formula for the nth term of a geometric sequence, which is given as: [tex]aₙ = a₁ * r^(n-1)[/tex]
Here, aₙ represents the nth term of the sequence (the term we are trying to find), a₁ is the first term (2 in this case), r is the common ratio (4 in this case), and n is the position of the term we are trying to find (7 in this case). Plugging in the given values, we get: a₇ [tex]= 2 * 4^(7-1) = 2 * 4^6 = 2 * 4 * 4 * 4 * 4 * 4 * 4 = 2 * 4,096 = 8,192[/tex]Therefore, the 7th term of the geometric sequence 2, 8, 32, 128, ... is 8,192.

Answer:
11°
Step-by-step explanation:
Kindly find the diagram attached.
From the diagram we are given two interior angles ∠NLM and ∠LMN and exterior angle ∠MNO.
You must understand that sum of interior angles is equal to the exterior angles.
∠NLM+ ∠LMN = ∠MNO
Given parameters
∠NLM = x-4
∠LMN = x+9
∠MNO = 4x-17
Substitute the given parameters into the equation above;
x-4+x+9 = 4x-17
2x+5 = 4x-17
2x-4x=-17-5
-2x = -22
x = -22/-2
x = 11°
Hence the value of x is 11°

Answer:
B) x<= 0
Step-by-step explanation:
of you look at the graph, the line stops at the coordinates (0, 9)
the x coordinate here is 0. so x<0.
since it's a closed circle around where the line ends, the domain becomes
x <=0
the rest of the line goes on for infinity, so that's all of the equation.

This year consumers purchased 7,234,267,990 bottles of water. Last year consumers purchased 2,000,900,999 bottles of water. Which is the best estimate of the number of bottles sold this year and last year? A. 5,000,000,000 B. 9,000,000,000 C. 9,235,168,989 D. 10,000,000,000
Answer:
B. 9,000,000,000
Step-by-step explanation:
From the given information:
We are to determine the best estimate of the number of bottles sold this year and last year.
The best estimate means rounding up to the nearest whole number.
Given that:
7,234,267,990 bottles of water were purchased this year
2,000,900,999 bottles of water were purchased last year
The estimate of the bottles sold this year and last year from the above value is:
= 7,000,000,000 + 2,000,000,000
= 9,000,000,000
is 0.124356 rational or irrational
57 Team one had twice as many workers as team two. Because of increased productivity the number of workers in team one was reduced by 5 and the number of workers in team two was reduced by 2. How many workers are there in each team now if there are 7 more workers in team one?
Answer:
Team 1 = 15 workers
Team two = 8 workers
Step-by-step explanation:
Let
Number of workers in team 1 = x
Number of workers in team 2 =y
Team one had twice as many workers as team two
x = 2y (1)
number of workers in team one was reduced by 5 and the number of workers in team two was reduced by 2.
x - 5 = y - 2
How many workers are there in each team now if there are 7 more workers in team one?
x - 5 = (y - 2) + 7
x - 5 = y - 2 + 7
x = y - 2 + 7 + 5
x = y + 10
Substitute x = y + 10 into (1)
x = 2y
y + 10 = 2y
10 = 2y - y
10 = y
y = 10
Substitute y = 10 into (1)
x = 2y
= 2(10)
= 20
x = 20
The team now has
Team 1 = x - 5
= 20 - 5
= 15 workers
Team 2 = y - 2
= 10 - 2
= 8 workers

Danielle and Emilia brought apples, bananas, and oranges to a fruit sale.
The bananas were sold for $0.50 each, while the apples and oranges
were sold for $0.75 each. They sold 50 pieces of fruit and earned $33.50
total. If Danielle and Emilia sold twice as many bananas as oranges, how
many apples did they sell? Show your work.
*
Can you please Write the system which models this situation as well!!
Answer:
26 apples
Step-by-step explanation:
bananas, b= $0.50
oranges, o= $0.75
apples, a = $0.75
Total fruit sold = 50
Total Earned = $33.50
b + o + a = 50 Because the total number of all 3 fruits sold is 50
.5b + .75o + .75a = $33.50 The number of each fruit, multiplied by the price of each fruit, and added together is $33.50
They sold twice as many bananas than oranges.
If o is oranges, then 2o = b because there are twice as many bananas so:
b + o + a = 50
2o + o + a = 50
3o + a = 50
Now we can solve.
3o + a = 50
a = 50 - 3o
.5b + .75o + .75a = $33.50
.5(2o) + .75o + .75a = $33.50
o + .75o + .75a = $33.50
1.75o + .75a = $33.50
Two equations and 2 unknowns.
a = 50 - 3o
1.75o + .75a = $33.50 Plug in a to solve for o.
1.75o + .75(50 - 3o) = $33.50
1.75o + .75*50 - .75*3o = $33.50
1.75o + 37.5 - 2.25o = $33.50 Combine like terms
1.75o - 2.25o +37.5 = $33.50
-.5o + 37.5 = 33.5 Add .5o to each side so it cancels on the left.
37.5 = 33.5 + .5o Subtract 33.5 from each side
37.5 -33.5 = .5o
4 = .5o Divide each side by .5
4/.5 = o
8 = o
Now plug into a = 50 - 3o
a = 50 - 3(8)
a = 50 - 24
a = 26
So even though we know they sold 26 apples, let's finish solving to check our work.
b + o + a = 50
b + 8 + 26 = 50
b + 34 = 50
b = 50 - 34
b = 16
b = 2o
b = 2 (8)
b = 16 Which works! Now the last step of checking our work:
.5b + .75o + .75a = $33.50
.5(16) + .75(8) + .75(26) = $33.50
8 + 6 + 19.5 = $33.50
14 + 19.5 = $33.50
33.5 = $33.50 Yes! It works too!
bananas = 16
oranges = 8
apples = 26

1. Calculate the area (use π= 3.14)
Circumference =314m
2. Calculate the circumference (π=3.14)
1. 10cm
2. 10.2cm
3. A=314m2
Answer:
Step-by-step explanation:
Circumference = 314
2*pi*r = 314
2*r = 314 / 3.14
2*r = 100
r = 50
Area = pi * r^2
Area = 3.14 * 50^2
Area = 3.14 * 2500
Area = 7850
===========
C = 2*pi * r
C = 2 * 3.14 * 10
C = 6.28 * 10
C = 62.80 cm
==========
C = 2*3.14*10.2
C = 64.056
==========
Area = pi * r^2
314 = 3.14 * r^2
314 / 3.14 = r^2
100 = r^2
sqrt(100) = sqrt(r^2)
r = 10
C = 2*pi *r
C = 2*3.14 * 10
C = 6.28 * 10
C = 62.8
