Consider the figure.
Find the area of the composite figure shown to the nearest half unit.
Answers
Answer:
Area = 13
Step-by-step explanation:
see image. There's a brick of 8 whole squares on the bottom. Then a layer of 3 whole squares on top of that. There's a 1/2 a square besides the 3. Then on top, there is half of a layer of 3 squares. Half of 3 is 1 1/2.
8 + 3 + 1/2 + 1 1/2
= 8 + 3 + 2
= 13

Translate the figure using the rule (x + 6, y + 1) and then reflect over the x- axis.
(Enter the ordered pairs in parenthesis without space bar, like (-3,9) )
WILL GIVE BRAINLIEST
Answers
Step-by-step explanation:
well, the translation (x+6, y+1) creates the following points :
D goes from (-4,-4) to (2,-3)
E goes from (-4,-2) to (2,-1)
A good from (-1,-4) to (5,-3)
the reflection over the x-axis leaves then the x values unchanged, and negative y values turn positive (or vice versa, if we had a case here).
so,
D' = (2,3)
E' = (2,1)
A' = (5,3)

13. An elephant takes 8 steps in 10 seconds. At this rate, how many steps does it take in 4 minutes?
Answers
Answer:
192
Step-by-step explanation:
8 steps per 10 seconds
How many steps per 4 minutes?
First, find out how many 10-second intervals there are in 4 minutes.
4 minutes = 240 seconds
240 divided by 10 is 24
24 ten second periods times 8 steps per 10 seconds
192
192 steps in 4 minutes
Solve for the missing variables. (Geometry)
Answers
Step-by-step explanation:
we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.
in other words
h² = p×q
h = height
p, q are the 2 segments of the Hypotenuse.
so, in our case we have
100 = x(x + 21) = x² + 21x
that gives us the following quadratic equation
x² + 21x - 100 = 0
the general solution to a quadratic equating is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 21
c = -100
so,
x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =
= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =
= (-21 ± 29)/2
x1 = (-21 + 29)/2 = 8/2 = 4
x2 = (-21 - 29)/2 = -50/2 = -25
x2 would give us negative lengths for the triangle, which does not make sense.
so, x = 4 is our solution.
that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).

Step-by-step explanation:
Area of a triangle
The area of a triangle can be calculated using the formula
A = bh/2 where b = base length and h = height
Finding the area by plugging in the values of the height and base length
Looking at the triangle we can tell that the base length is 8 and the height is 10. ( so b = 8 and h = 10 )
So we have A = bh/2
==> plug in b = 8 and h = 10
A = (8)(10)/2
==> multiply 8 and 10
A = 80/2
==> divide 80 by 2
A = 40
