The diagram represents a reduction of a triangle by using a scale factor of 0.8.
A larger triangle has a base of 10 inches and height of 6 inches.
What is the height of the reduced triangle?
4.0 inches
4.8 inches
5.2 inches
7.5 inches
Answer:
I think it's 4.8 inches :/
Explanation:
6(t - 1) = 9(t - 4)
t = ?
t = 43
My reasoning is that I just did this and if you were to times 4 x 9 you would get minus ce tre avergae t pens
need help to Find the apothem.
The apothem of a polygon, in this case a, can be found using the formula
Apothem=circumradius*cos(pi/sides)
Note in this problem, its a hexagon which makes the circumradius = to the side length since a regular hexagon can be split into 6 equilateral triangles.
a=47*cos(pi/6)=40.7 (approximation)
Hope it helped!
Which expressions could be used to find the distance between points (-2, 8) and (7, 13) on a coordinate plane
Answer:
Step-by-step explanation:
Note how the stretch from x = -2 to x = 7 could be regarded as the horizontal leg of a right triangle (9 units in length), and that from y = 8 to y = 13 the vertical leg (5 units in length). We need to find the length of the hypotenuse of this triangle, using the Pythagorean Theorem:
d = √(5² + 9²) = √106, or approximately 10.3 units.

102
54
6x
O A. 8
B. 6
O C. 17
D. 9
Answer:
A. 8
Step-by-step explanation:
Given,
54° + 6x° = 102°
=> 6x = 102 - 54
=> 6x = 48
[tex] = > x = \frac{48}{6} [/tex]
=> x = 8(Ans)
Let f(x)=x√x-4
What is the average rate of change of f(x) from 8 to 14?
Answer:
Avg rate of change =
[ f(14 ) - f(8) ] / [ 14 - 8 ] =
[ ( √ [14 - 4] ) - (√ [8 - 4]) ] / 6 =
[ √10 - √4 ] / 6 =
0.19

What is the solution to
-3/7m <21?
m<49
m>49
m>-49
m<-49
9514 1404 393
Answer:
(c) m > -49
Step-by-step explanation:
To solve, multiply by the reciprocal of the coefficient of m. Because that is negative, the inequality symbol must be reversed.
(-3/7)m < 21
(-7/3)(-3/7)m > (-7/3)(21)
m > -49
the length of a rectangle is 1 more than 4 times the width. the perimeter is 92 in. what is the length and width.
Step-by-step explanation:
the 1st side length is 4x+1 if x is the width. 2(length)+2(width)=perimeter
2(4x+1)+2x=92
8x+2+2x=92
10x=90
x=9
width=x=9
length=4x+1=4(9)+1=37
Hope that helps :)
