Answer:
∠G
Step-by-step explanation:
The tangent of an angle is given by the following trigonometric ratio;
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}[/tex]
From the question, we have;
tan ∠K = 6/8
ΔGIH is similar to ΔKJL
By observation of the length, we have;
Segment HI and segment JL are corresponding segments
Segment KL and segment HG are corresponding segments
∴ ∠K and ∠G are corresponding angles
∴ tan∠G = tan∠K = 6/8
The angle whose tangent is 6/8 is ∠G
What is the expression and value of "six less than nine times the sum of a number and eight" when n = 5? 9 (n + 8) minus 6; when n = 5, the value is 111. 6 minus 9 (n + 8); when n = 5, the value is 111. 9 (n) + 8 minus 6; when n = 5, the value is 47. 6 minus 9 (n) + 8; when n = 5, the value is 47.
Answer:
Answer:
The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A plz mark me brainlest
Step-by-step explanation:
* Lets explain how to solve the problem
- We have a statement:
" six less than nine times the sum of a number and eight"
- When we solve we will start by the last part
- The last part is the sum of a number and 8
- Assume that the number is n
∵ The sum is the answer of adding
∴ The sum of a number and eight is ⇒ n + 8
- Nine times the sum
∵ The sum is n + 8
∵ Nine times means multiply the sum by 9
∴ Nine times the sum is ⇒ 9(n + 8)
- Six less than nine times the sum
∵ Nine times the sum is 9(n + 8)
∵ Six less than means subtract 6 from nine times the sum
∴ Six less than nine times the sum is ⇒ 9(n + 9) - 6
* The expression is 9(n + 8) - 6
- Lets evaluate the expression when n = 5
∵ 9(n + 8) - 6
∵ n = 5
∴ The value = 9(5 + 8) - 6
∴ The value = 9(13) - 6
∴ The value = 117 - 6
∴ The value = 111
* When n = 5 the value of the expression is 111
Step-by-step explanation:

A teacher has 20 students. Each student is paying $12.50 for a ticket to see a play during a field trip. The teacher collects their money for two weeks. In the first week, 14 students pay for their ticket. In the second week, the rest of the students pay for their ticket. How much did the teacher collect in the second week?
Answer:
$75
Step-by-step explanation:
Steps to determining the answerDetermine the number of students that would pay in the second week. This can be known by subtracting 14 from 20. 20 is the total number of students. 14 is the number of students that paid in the first week. Multiply the answer gotten from one above by the price of the ticket20 - 14 = 6
6 students would pay in the second week
6 x $12.50 = $75
The teacher would collect $75 in the second week

Amanda wants to buy 15 dollars worth of candy. The gummy worms cost $1.50 per pound and the peanut
butter cups cost $3 per pound. Let x be the amount of gummy worms in pounds and y be the amount of peanut
butter cups in pounds.
Answer:
C = $1.50x + $3y
Step-by-step explanation:
Using the information provided we can create an equation to model the total dollar cost of Amanda's purchase when visiting the candy store. To do this we need to multiply each candies individiual cost by the amount of each candy they are purchasing. Then we add together all of these values to get the final total cost which would be represented by C.
C = $1.50x + $3y

A rectangular sandbox is in the center of a larger rectangular back yard. The sand box
measures (x+6) feet long and 5x feet wide. The yard measures (6x+7) feet long and 8x
feet wide.
What is the area of the yard that is NOT apart of the sandbox?
Answer:
(43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex]
Step-by-step explanation:
Area of the yard that is not pat of the sandbox = Area of the yard - Area of the sandbox
Since both the yard and the sandbox has a rectangular shape, then;
Area of a rectangle = length x width
So that,
Area of the yard = length x width
= (6x+7) x 8x
= (48[tex]x^{2}[/tex] + 56x) [tex]ft^{2}[/tex]
Area of the sandbox = length x width
= (x+6) x 5x
= (5[tex]x^{2}[/tex] + 30x) [tex]ft^{2}[/tex]
Thus,
Area of the yard that is not pat of the sandbox = (48[tex]x^{2}[/tex] + 56x) - (5[tex]x^{2}[/tex] + 30x)
= 48[tex]x^{2}[/tex] + 56x - 5[tex]x^{2}[/tex] - 30x
= (43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex]
Area of the yard that is not pat of the sandbox is (43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex].

In the figure, ZJKM and ZMKN are
complementary.
What is the measure of ZNKP?
Answer:
angle NKP = 60 degrees
Step-by-step explanation:
A line will always equal 180 degrees
If angle JKM and angle MKN are complentary, that means they will add up to 90. Since angle JKM is 40 degrees, angle MKN must be 50 degrees
Angle LKP is 30 degrees
Form an equation:
180 = 40 + 50 + 30 + angle NKP
Combine like terms
180 = 120 + angle NKP
Subtract 120 from both sides to isolate the unknown angle
60 = angle NKP

Amy owns 3 1/3 acres of farmland. She grows beets on 1/6 of the land. On how many acres
of land does Amy grow beets?
Plz
Answer:
5/9 acres
Step-by-step explanation:
3 1/3 areas is 10/3
1/6 of the land is covered with beets
[tex]\frac{10}{3} * \frac{1}{6} =\frac{10}{18}[/tex]
[tex]\frac{10}{18}[/tex] will simplify to [tex]\frac{5}{9}[/tex]
Hence the answer is 5/9 acres

A pedestal for a statue is made with 405 cubic feet of concrete. What is the area of the base of the pedestal? 6.7 square feet 22.5 square feet 45 square feet 3,645 square feet
Complete Question:
A pedestal for a statue is made with 405 cubic feet of concrete. A rectangular prism with a height of 9 feet.
What is the area of the base of the pedestal?
Answer:
45 square feet
Step-by-step explanation:
Given the following data;
Volume of pedestal = 405 ft³
Height of rectangular prism = 9 ft
To find the area of the base of the pedestal;
Volume of pedestal = base area * height
405 = base area * 9
Base area = 405/9
Base area = 45 square feet.
Therefore, the area of the base of the pedestal is 45 square feet.
Answer:
45 square feet

Answer:
25.6125
Step-by-step explanation:
since 25 is a whole number, it'd be 25.ˣˣˣˣ
now all you have to do it divide the fraction so 49 ÷ 80 = 0.6125
last step is to add ⇒ 25 + 0.6125 = 25.6125
