Answer:
1,000 + 50= 1,050
400 + 15= 430
15 x 2 = 30
Their bill would be 1,050 + 430= 11480

Answer:
Emanuel made huis mistake in first step and step 1 is incorrect.
Step-by-step explanation:
The given expression is
(\frac{3}{5})(\frac{4}{9})(-\frac{1}{2})(

)
It can be written as
\frac{3}{5})(\frac{4}{9})(\frac{-1}{2}
5

−1
Step 1: (\frac{(3)(4)(-1)}{(5)(9)(2)})(
(5)(9)(2)
(3)(4)(−1)
)
Emanuel used negative sign with both numbers 1 and 2. Therefore the first step of Emanuel is incorrect.
Step 2: \frac{-12}{90}
90
−12
Step 3: \frac{-2}{15}
15
−2
Therefore Emanuel made huis mistake in first step and step 1 is incorrect
Step-by-step explanation:
all the steps are given below
Answer:
Step-by-step explanation:
The equation for this free fall problem is
where h(t) is the height of the pebble from the ground at any time t. If we are looking for the time it takes the pebble to hit the ground, knowing that at ground level the height is 0, we set the quadratic equal to 0 and solve for t:
and
and
so
t = -8, 8
Since time will never be negative,
t = 8 seconds
Part A 60x3=180
5x30=150
150+180=330 sry only doing part A
We need to identify the perimeter of the rectangle EFGH which has points as below:
G (-3, 4)
H (2, 2)
E (1, -1)
F (-4, 1)
The distance of EF, we have it:
d² = (-4-1) ² + (1--1)² = 25 + 4 = 29
d = √29
The distance from point F to point G:
d² = (-4--3)² + (1-4)² = 1 + 9
d = √10
Hence, we can solve for the perimeter as below:
Perimeter EFGH = 2L + 2W
Perimeter EFGH = 2(√29) + 2(√10)
Perimeter EFGH = 17.09 units
The answer is the second item in the choices or the letter B which is 2√10 + 2√29 units.
