A flower bed is in the shape of a triangle, with a base of 13 feet and a height of 5 feet. What is the area of the flower bed?
1. 18 square feet
2. 32.5 square feet
3. 65 square feet
4. 130.5 square feet
Answer:
32.5
Step-by-step explanation:
For triangles you need to do base times height divided by 2
Answer:
Number 2: 32.5 square feet
Step-by-step explanation:
The formula for the area of a triangle is 1/2(base)(height)
In this case, our base is 13 ft and our height is 5 ft so we plug in those values into our formula
A = 1/2(13)(5) = 32.5
Therefore our area is 32.5 square feet.
Raul wants to buy a new collar for each of his 5 dogs. The collars come in a choice of 10 different colors. Step 1 of 2 : How many selections of collars for the 5 dogs are possible if repetitions of colors are allowed
Answer:
100,000
Step-by-step explanation:
Calculation for How many selections of collars for the 5 dogs are possible if repetitions of colors are allowed
Based on the information given since he has 5 dogs that he want to purchase a collar for, which means that if the collar has 10 choice of variety of colors, then the selection of collars for the 5 dogs if repetitions of colors are allowed will be calculated as:
Selections of collars=10*10*10*10*10
Selections of collars=100,000
Therefore the numbers of selections of collars for the 5 dogs that are possible if repetitions of colors are allowed is 100,000

Answer:
Area of circular trail = 7.1 square miles
Step-by-step explanation:
Given that:
Distance covered by Mr. Baker = 6 miles
As this distance is of both sides, we will divide it by 2 which will give us the diameter of the circle.
Distance of one side = 6/2 = 3 miles
Diameter = 3 miles
Radius = 3/2 = 1.5 miles
Area of circle = [tex]\pi r^2[/tex]
Area of circle = [tex]3.14*(1.5)^2[/tex] = 3.14 * 2.25
Area of circle = 7.065 = 7.1 square miles
Hence,
Area of circular trail = 7.1 square miles
What is the result of adding these two equations?
- 2x + y = -5
- 2x - 4y = 6
Answer: 5y = -11
Step-by-step explanation:
-2x + y = -5
(-2x - 4y = 6) -1
-2x + y = -5
2x + 4y = -6
System by elimination method
0 + 5y = -11
5y = -11
Answer:
-4x-3y=1
Step-by-step explanation:
when adding the wo equations, u must add like ters. -2x+-2x is -4x. and positive y+ -y= -3y and-5+6=1. so if u put it all together after adding all integers you get -4x-3y=1
If 2.29 x 19.79 = 45.3191, then without actual multiplication the value of 0.0229 x 1979 is?
If you answer this first, I will give brainliest.
Answer:
45.3191
Step-by-step explanation:
0.0229 is 100 times smaller that 2.29 but 1979 is 100 times greater than 19.79. Since they cancel each other out, the answer remains the same.

: Discuss the continuity of the function f(x)=xtan(1/x) at x = 0 given that x≠0 and f(0)=0.
Answer:
Left hand Limit = Right Hand Limit = f(a)
it is a continuous function.
Step-by-step explanation:
Solution:
In order to find out the continuity of the function, we need to keep in mind following things:
Left hand Limit = Right Hand Limit = f(a)
Where, f(x) = exists and f(a) = defined.
Data Given:
f(x) = x tan(1/x) x [tex]\neq[/tex] 0 (this function is used when x > 0 and x<0)
f(x) = 0 when x = 0
First we have to check the Left hand Limit.
L.H.L = f(0-h) (x<0)
Lim[tex]_{x-->0^{-} }[/tex] f(x)
Lim[tex]_{x-->0^{-} }[/tex] x tan (1/x)
Put x = 0-h
Lim[tex]_{x-->0^{-} }[/tex] (0-h) tan (1/(0-h))
Lim[tex]_{x-->0^{-} }[/tex] h tan (1/h)
Putting h = 0
(0) x (tan(1/0)))
As we know, for tanx value is a finitely oscillatory between -∞ to +∞
Hence, 0 x finite number then,
L.H.L = 0
Similarly,
R.H.L = f(0+h)
Lim[tex]_{x-->0^{+} }[/tex] (0+h) tan (1/(0+h))
Lim[tex]_{x-->0^{+} }[/tex] (h) tan (1/(h))
R.H.L = 0
Now, as we know, when x = 0
f(x) = 0
f(0) = 0
Left hand Limit = Right Hand Limit = f(a)
Hence, it is a continuous function.
Solve the following system of equations using substitution or elimination: y = −8x − 9 y = −6x + 5
Answer:
x = -7
y = 47
Step-by-step explanation:
Given the system of equation
y = −8x − 9 ... 1
y = −6x + 5 ...2
Equating both expressions
-8x - 9 = -6x + 5
Collect like terms
-8x + 6x = 5 + 9
-2x = 14
x = 14/-2
x = -7
Substitute x = -7 into equation 1.
From 1: y = −8x − 9
y = -8(-7) - 9
y = 56 - 9
y = 47
Hence the solution to the system of equations (x, y) is (-7, 47)

1. Enter the linear inequality shown in the graph.
Answer:
y=1/3x+2
Step-by-step explanation:
Find two points and find the x and y distance between them to get the slope. I did (0,2) and (6,0), and the distance between them was 2/6 which simplifies into 1/3.
Then (0,2) is the y-intercept because it's where the line crosses the y-intercept.

The supreme choice pizza at Maria's Pizza Palace contains 2 different meats and 4 different vegetables. The customer can select any one of 5 types of crust. If there are 4 meats and 7 vegetables to choose from, how many different supreme choice pizzas can be made
Answer: Number of different supreme choice pizzas that can be made is 1050
Step-by-step explanation:
Given the data in the question;
Number of ways in which crust can be selected = 5
Number of ways in which 2 meats can be selected from 4 = ⁴C₂
⇒ 4! / ( 2! x (4-2)! )
= 6
Number of ways in which 4 vegetables can be selected from 7 = ⁷C₄
⇒ 7! / ( 4! x (7-4)! )
= 35
so; Number of different supreme choice pizzas that can be made;
⇒ 5 × 6 × 35
= 1050
Therefore, Number of different supreme choice pizzas that can be made is 1050
A six-month $3600 treasury bill sold for $3411. What was the simple annual discount rate?
Answer:
0.9235%/month
Step by step explanation:
r = (1/6)((3600/3411) - 1) = 0.00923483
r = 0.00923483
Converting r decimal to R a percentage
R = 0.00923483 * 100 = 0.9235%/month

The pyramid has a base that is a right
triangle with side lengths 3 feet , 4 feef , 5 feet .it’s height is 6 feet. What is the volume of the pyramid?
Answer:
36
OR
12
?
Step-by-step explanation:
Area of Triangle: [tex]\frac{3*4}{2} = 6[/tex]
Volume: 6*6 = 36
Pyramid part confuses me.
volume of a pyramid: [tex]\frac{1}{3}*B*H[/tex] = [tex]\frac{1}{3}*6*6[/tex] = 12
B = triangle area
H = height
