Answer:
B) 72
Step-by-step explanation:
The value of 80-2n when n=4 can be found by substituting n=4 into the expression and simplifying. Therefore:
80-2n = 80 - 2(4) = 80 - 8 = 72
Therefore, the answer is B) 72.
[tex] \sf80 - 2n[/tex]
Put n = 4
[tex] \tt80 - 2 \times 4 \\ \tt80 - 8 \\ \boxed{ \sf\underline{ \underline{72}}}[/tex]
Thus, The correct answer is option B!! :)help me pls, thanks :)
The perimeter of △PQR is 94 units. QS bisects ∠PQR
. Find PS and RS. Round to the nearest tenth, if necessary.
The length of PS is 18.4 units and the length of RS is 24 units.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
Given that, the perimeter of ΔPQR is 94 units.
From the figure, PQ+QR+PR=94
22.4+29.2+PR=94
51.6+PR=94
PR=94-51.6
PR=42.4 units
By bisector theorem of interior angle of triangle
Take PS=x and RS=42.4-x
We have PS/RS=QP/QR
x/(42.4-x)=22.4/29.2
x/(42.4-x)=0.77
x=0.77(42.4-x)
x=32.5-0.77x
1.77x=32.5
x=32.5/1.77
x=18.4
So, PS=18.4 and RS=42.4-18.4=24 units
Therefore, the length of PS is 18.4 units and the length of RS is 24 units.

Which of the following measures would create only ONE possible triangle?
three angles of 39°, 68°, and 69°
two sides of 4 cm and 7 cm with an angle of 54° not between those two sides
a 63° angle between two sides of length 4 cm and 7 cm
Answer:
a 63° angle between two sides of length 4 cm and 7 cm.
Step-by-step explanation:
A triangle can only be formed if the sum of any two sides is greater than the third side, and in the case of angles, the sum of the angles must be equal to 180 degrees. Using these principles, we can determine which measure would create only one possible triangle:
three angles of 39°, 68°, and 69°: This set of angles does not form a triangle because the sum of the angles is 176°, which is less than the required 180°. Therefore, no triangle can be formed with these angles.two sides of 4 cm and 7 cm with an angle of 54° not between those two sides: This set of measures can form two possible triangles. To see why, imagine drawing a line segment of length 7 cm, then drawing two circles centered at the endpoints with radii of 4 cm. The two circles will intersect at two points, and these points represent the two possible locations for the third vertex of the triangle. Therefore, there are two possible triangles that can be formed with these measures.a 63° angle between two sides of length 4 cm and 7 cm: This set of measures can only form one possible triangle. To see why, note that the angle opposite the side of length 4 cm must be less than 63° (since the sum of angles in a triangle is 180°). Likewise, the angle opposite the side of length 7 cm must be greater than 63°. Therefore, there is only one possible location for the third vertex of the triangle, and hence only one possible triangle can be formed with these measures.Please answer and explain

et x= what she started with.
x*7/8=7x/8
7x/8*1/2=7x/16
7x/16*2/7=14x/112
14x/112=x/8
so 1/8 of what she started with=25 coins
x/8=25
x=25*8 multiply both sides times 8.

Myra polled twenty-five students in her class to determine the number of movies the students attended at the theater this year. The results are in the table. She decided to find the mean of a sample using Row 1 and Row 5.
What is the mean of her sample?
2
4
6
8
Answer: 4
Step-by-step explanation: How to find the mean of sample?
Mean of sample = (sum of data values of sample)/(size of sample)
(it is because size of sample = number of data values in sample)
For the given case, the population is
Row 1: 6 5 2 8 6
Row 2: 2 0 4 5 2
Row 3: 3 4 3 0 1
Row 4: 5 2 6 3 3
Row 5: 2 3 2 2 4
The sample Myra select is: Row 1 and Row 5.
Sample values are: 6, 5, 2, 8, 6, 2, 3, 2, 2, 4
Mean of sample = (6+5+2+8+6+2+3+2+2+4)/10 =40/10 = 4
Thus, The mean of Myra's sample is 4

A line passes through the points (2,2) and (3,9). What is its equation in point-slope form?
slope formula
(y2-y1) / (x2-x1)
(9-2) / (3-2) = 7
slope 7
point (2,2)
y - y1 = m(x - x1)
y = m(x-x1)+y1
y = 7(x-2) + 2
A student is measuring the length of an icicle, y, every hour, x. The icicle is currently 12 inches long and is melting at a rate of 0.7 inches per hour. Find and interpret the slope for this relationship.
12; the length of the icicle when the student first measures it
−12; the length of the icicle when the student first measures it
0.7; for every additional hour, the length of the icicle increases by 0.7 inches
−0.7; for every additional hour, the length of the icicle decreases by 0.7 inches
Answer: 55 inches
Step-by-step explanation:
I think so
Answer: −0.7; for every additional hour, the length of the icicle decreases by 0.7 inches
Step-by-step explanation:
It says find an interpret the slope.
Slope is also known as the rate of change.
It wants you to find how the rate of change which in this case would be how much it melts every hour.
It says it melts every 0.7 inches per hour, since it says melts it means take away so your answer is going to be a negative.
so turn 0.7 into a negative and you have your slope.
So your answer is -0.7
