1/2,×5×945/222.5cm²stay safe healthy and happy..Of the 68 students on a field trip 17 students bring a camera. What percent of the students bring cameras?
Answer: 25%
Step-by-step explanation:
Given
Total students on a field trip are 68
Out of 68, only brings the camera
The percentage of students that bring the camera is given by
[tex]\Rightarrow \dfrac{17}{68}\times 100\\\\\Rightarrow \dfrac{1}{4}\times 100=25\%[/tex]

Determine the scale factor for A ABC to A A'B'C:
A. 1/2
B. 10
C. 5
D. 2
The required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.
The scale factor of the ΔABC to ΔA'B'C' is to be determined, while one of each side of the triangle has lengths 5in and 10 in respectively.
The scale factor is defined as the ratio of modified change in length to original length.
Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Since the scale factor only applies to similar shapes so as the two triangles are similar then the ratio of the side will describe the scale factor between two triangles.
Scale factor = A'C'/AC
= 10 /5
= 2 in
Thus, the required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.

plz help asap.. I have no clue how to do this.
Answer:
Tn=a + (n-1)d
a= first term = 14
n= This is the term you're looking for... In this case... That's the 73rd term
d=Common difference (since its an AP)
d= second term - first term -- Or 3rd term - 2nd term = 23-14
d=9
T = 14 + (73-1)9
T= 14 + (72)9
T= 14 + 648
T=662.
The 73rd term would be 662.
1 term is +9
10 terms is +90
90x7=630
9x2=18
630+18=648

Which is the best description for the lines m and k?
A)
parallel
B)
perpendicular
intersecting and parallel
D
intersecting but not perpendicular
===================================================
Explanation:
I've highlighted lines m and k in red (see diagram below). We'll ignore the other lines. On those red lines, I've added blue points with their coordinate locations.
Line m has point A = (-3, 5) and B = (-1, -3). Let's use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-3-5)/(-1-(-3))
m = (-3-5)/(-1+3)
m = -8/2
m = -4
The slope of line AB, aka line m, is -4.
-------------
Line k has points C = (1, 5) and D = (3, -3) on it. We'll use the slope formula to get...
m = (y2-y1)/(x2-x1)
m = (-3-5)/(3-1)
m = -8/2
m = -4
The slope of line CD, aka line k, is -4
---------------
Both lines m and k have the same slope of -4. Therefore, the two lines are parallel. Parallel lines always have the same slope, but different y intercepts. So these lines will never intersect one another.

the sum of the angle measures triangle is 180⁰ find the measures of each angle in the triangle below
Answer:
∠ABC= 82°
∠ACB= 82°
∠BAC= 16°
Step-by-step explanation:
∠ABC +∠ACB +∠BAC = 180° (∠ sum of △ABC)
(5x -3)° +(5x -3)° +(x -1)°= 180°
5x -3 +5x -3 +x -1= 180
11x -7= 180 (simplify)
11x= 180 +7 (+7 on both sides)
11x= 187
x= 187 ÷11
x= 17
∠ABC
= (5x -3)°
= [5(17) -3]°
= 82°
∠ACB
= ∠ABC
= 82°
∠BAC
= (17 -1)°
= 16°
Alternatively,
∠BAC
= 180° -82° -82°
= 16°

Step-by-step explanation:
To fins the area if the rectangle you need to find the hypotenuse of the triangles, which are equal. so 10.4 squared plus 15.3 squared is 342.25, and the square root is 18.5.
Then, 18.5 multiplied by 7 is 129.5. Then to fins the area of a triangle you need to do it like a rectangle but in this case, sense there are 2, then just find the area. 129.5+(10.4 times 15.3=159.12)=129.5+159.12=288.62
