A farmer plants a 16-foot row of tomatoes 13-foot row of carrots and a 21-foot row of green peppers in a triangle find the angle formed by the tomatoes and carrots
Answer:
The angle between tomatoes and carrots is 92.2°, approximately.Step-by-step explanation:
As you can observe in the image attached, the triangle formed is scalene, which means we need to use the law of cosines to find the answer.
[tex]p^{2} =c^{2} +t^{2} -2(c)(t)(cos\theta)[/tex]
Where [tex]p[/tex] is green peppers, [tex]c[/tex] is carrots, [tex]t[/tex] is tomatoes and [tex]\theta[/tex] is the angle between tomatoes and carrtos.
Replacing all given values, we have
[tex]21^{2} =13^{2} +16^{2} -2(13)(16)(cos\theta)\\441=169+256-416cos\theta\\441-169-256=-416cos\theta\\\frac{16}{-416}=cos\theta\\ \theta=cos^{-1}(\frac{1}{-26} ) \approx 92.2\°[/tex]
Therefore, the angle between tomatoes and carrots is 92.2°, approximately.

What is the longest line segment that can be drawn in a right rectangular prism that is 15cm long, 8 cm wide, and 7 cm talk
Answer:
=18.38cm
Step-by-step explanation:
The longest line segment in a right rectangular prism is the diagonal that connects two opposite vertices. On the first diagram attached, the green line segment connecting A and G is one such diagonals. The goal is to find the length of segment .
Look at the attached picture. The longest segment we can draw is AG (or any of its equivalent: BH, CE, DF). Let's focus on AG for example.
We can think of AG as the hypotenuse of triangle ACG. So, we need AC first. AC is itself the hypotenuse of triangle ABC,
so we have,
[tex]AC^2 = AB^2+BC^2=8^2+7^2=113[/tex]
Now we can resume where we stopped with triangle AGC, and we have
[tex]AG=\sqrt{AC^2+CG^2}=\sqrt{113+225}=\sqrt{338}[/tex]
=18.38cm

find the missing angle in the triangle
Answer:
60
Step-by-step explanation:
Since all of the sides of this triangle are shown to be congruent, this must be an equilateral triangle. In an equilateral triangle, all of the angles are equal to 60 degrees. Therefore, x is 60. Hope this helps!
Answer:
60
Step-by-step explanation:
If all sides all have the same angles then we will divide 180 by 3 which will give us our answer 60.

Health Club Fees You are choosing between two health clubs Club A offers membership for a fee of $7 plus a monthly fee of $23. Club B offers membership for a
tee of $35 plus a monthly fee of $16. After how many months will the total cost of each health club be the same?
in month(s) the total cost of each health club will be the same
Answer: The solution is (4,99) which means for in 4 months the total cost of each health club will be the same.
Step-by-step explanation:
Club A can be represented by the equation y = 23x + 7 where x is the number of months and y is the cost.
Club B can be represented by the equation y = 16x + 35 where x is the number of months and y is the cost.
23x + 7 = 16x + 35 set the equation equal each other to solve for x
-7 -7
23x = 16x + 28
-16x -16x
7x= 28
x= 4 now we know the value of x is 4 so we will put it into the equation and solve for y
y= 16(4) + 35
y= 99

Determine the values of the variables in isosceles trapezoid CHLE below.
Enter numbers only, do not enter units.
Answer:
The values of variables x and m are 11 and 17
Step-by-step explanation:
The question has missing details as the diagram of the trapezoid isn't attached.
(See attachment).
Given that trapezoid CHLE is isosceles then the angles at the base area equal (4x)
And
The angles at the top are also equal
8m = 11x + 15
At this point, the four angles in the trapezoid are 8m, 11x + 15, 4x and 4x..
The sum of interior= 360
So,
11x + 15 + 8m + 4x + 4x = 360
Collect like terms
11x + 4x + 4x + 8m = 360 - 15
19x + 8m = 345
Substitute 11x + 15 for 8m
19x + 11x + 15 = 345
30x + 15 = 345
30x = 345 - 15
30x = 330
Divide through by 30
30x/30 = 330/30
x = 11
Recall that 8m = 11x + 15;
8m = 11(11) + 15
8m = 121 + 15
8m = 136
Divide through by 8
8m/8 = 136/8
m = 17
Hence, the values of variables x and m are 11 and 17
The volume of a cylinder is 40 ft which expression represents the volume of O.C. one with the same base and height as the cylinder
The volume of a cylinder is 40 ft which expression represents the volume of a Cone with the same base and height as the cylinder?
3(40) ft³
3(1/40) ft³
1/3(40)ft³
1/3(40²) ft³
Answer:
The expression that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³
Step-by-step explanation:
To find the expression that represents the volume of a cone with the same height and base as the cylinder, we will follow the steps below:
First write down the formula for calculating volume of a cone and volume of a cylinder
volume of a cone = [tex]\frac{1}{3}[/tex] πr²h
volume of a cylinder = πr²h
If the base are the same, this implies they have the same radius, and from the question, it states that they have the same height, hence;
volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)
from the question, the volume of the cylinder is 40 ft³
volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)
= [tex]\frac{1}{3}[/tex] (40) ft³
volume of a cone = [tex]\frac{1}{3}[/tex] (40) ft³
Therefore the expression that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³

A family plan to catch a ferry and need to book in at 12:02 am. The journey to the ferry port will take 2 hours 45 minutes. What time should they leave home in order to get to the ferry port on time?
Answer:
9:17 P.M.
Step-by-step explanation:
If the drive is 2 hours and 45 minutes and they need to be there by 12:02 am, you subtract two hours from that number. This means that if the drive was only two hours, they would have to leave home at 10:02 pm. However, it is 45 minutes longer than that so you have to subtract 45 minutes from 10:02 pm which gets 9:17 pm. Hope this helps!

It's the first expression
Step-by-step explanation:
9 (4a minus 3)
(9x4a)-(9x3)
36a minus 27
The correct expression equivalent to 36a minus 27 is 9(4a minus 3)
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, an expression is 36a minus 27, we need to find an expression equivalent to the given expression,
So, converting the expression into mathematical expression,
36a minus 27
= 36a-27
HCF of 36 and 27 is 9, so taking 9 common,
Therefore,
36a-27 = 9(4a-9)
We can write 9(4a-9) in statement,
9(4a-9) = 9(4a minus 3)
Hence, the correct expression equivalent to 36a minus 27 is 9(4a minus 3)
