Answer: 7km
Step-by-step explanation:
Hi, to answer this question, first we have to add the kilometers hiked in the first 2 days.
9km+6km= 15km
Since the trip was 36km, we have to subtract 15 to 36:
36-15= 21 km left
Since they hiked an equal number of km the next 3 days, we have to divide the remaining km by 3:
21/3 = 7km

A swimming pool is open for 7\dfrac127 2 1 7, start fraction, 1, divided by, 2, end fraction hours during a day. The pool keeps one lifeguard on duty at a time, and each lifeguard's shift is 1\dfrac121 2 1 1, start fraction, 1, divided by, 2, end fraction hours long. How many shifts are there per day?
Answer:
5 shifts
Step-by-step explanation:
The pool is open for 7 1/2 hours (15/2 hours) per day.
Each lifeguard shift lasts for 1 1/2 hours (3/2 hours).
To get the number of shifts per day, we divide the total hours that the pool is open by the time of each lifeguard shift:
[tex]\frac{15}{2} / \frac{3}{2} \\\\= \frac{15}{2} / \frac{2}{3} \\\\ = 5[/tex]
There are 5 lifeguard shifts per day.

Answer:
x = 80
Step-by-step explanation:
∠ ABC and ∠ DBC are adjacent angles and supplementary, thus
∠ ABC = 180° - ∠ DBC = 180° - 100° = 80°
∠ EFB = x = ∠ ABC = 80° ( corresponding angles )
Thus x = 80
Select the polynomial that is a perfect square trinomial. A. 49x^2 - 8x + 16 B. 4a^2 - 10a + 25 C. 25b^2 - 5b + 10 D. 16x^2 - 8x + 1
Answer:
(4x - 1)^2 = 16x^ - 8x + 1. This is a perfect square trinomial.
Step-by-step explanation:
Take a look at B: 4a^2 - 10 a + 25. The square roots of 4a^2 and 25 are 2a and 5 respectively. Does (2a - 5)^2 come out to 4a^2 - 10a + 25? No.
Take a look at C: 25b^2 - 5b + 10 We know this is not a perfect square trinomial because 10 is not a square.
D: 16x^2 - 8x + 1: both 16x^2 and 1 are perfect squares, so we have:
(4x - 1)^2 = 16x^ - 8x + 1. This is a perfect square trinomial.

Answer: 135°
Step-by-step explanation:
First, let's find the sum of the interior angles of an octagon (8-sided polygon).
S = 180(n - 2) where n = 8
S = 180(8 - 2)
S = 180(6)
S = 1080
Next, to find ONE angle, divide the sum by the number of angles in the polygon (octagon has 8 angles)
I = S/n
I = 1080/8
I = 135

Data A,
Graph for the data shows that there is a distinct value of y (output value) for every input value of x.
Therefore, Data A is a function.
Data B,
Each ordered pair shows exactly one output value for each input value.
Therefore, Data B represents a function.
Data C,
For each input value there is exactly one output value.
Therefore, Data C represents a function.

Step-by-step explanation:
The diagonals of quadrilateral ABCD intersect at E(−2,4). ABCD has vertices at A(1,7) B(−3,5). What must be the coordinates of C and D to ensure that ABCD is a parallelogram?
Answer:
The coordinates of C and D are (1, 3) and (-5, 1), respectivelly.
Step-by-step explanation:
Since E is the midpoint of diagonals AD and BC (see attachment). That is:
[tex]AD = 2 \cdot AE[/tex]
[tex]BC = 2\cdot BE[/tex]
The vectorial distances of AE and BE are, respectively:
[tex]\overrightarrow{AE} = \vec E - \vec A[/tex]
[tex]\overrightarrow {AE} = (-2,4) -(1,7)[/tex]
[tex]\overrightarrow{AE} = (-2-1, 4-7)[/tex]
[tex]\overrightarrow {AE} = (-3,-3)[/tex]
[tex]\overrightarrow{BE} = \vec E - \vec B[/tex]
[tex]\overrightarrow {BE} = (-2,4) - (-3,5)[/tex]
[tex]\overrightarrow {BE} = (-2+3, 4-5)[/tex]
[tex]\overrightarrow {BE} = (1,-1)[/tex]
Now, the relative vectorial distances to C and D are now obtained:
[tex]\overrightarrow {AD} = 2\cdot \overrightarrow {AE}[/tex]
[tex]\overrightarrow {AD} = 2 \cdot (-3,-3)[/tex]
[tex]\overrightarrow{AD} = (-6, -6)[/tex]
[tex]\overrightarrow {BC} = 2 \cdot \overrightarrow {BE}[/tex]
[tex]\overrightarrow{BC} = 2 \cdot (1,-1)[/tex]
[tex]\overrightarrow {BC} = (2,-2)[/tex]
Lastly, the coordinates are found by the following vectorial equations:
[tex]\vec C = \vec B + \overrightarrow {BC}[/tex]
[tex]\vec C = (-3,5) + (2,-2)[/tex]
[tex]\vec C = (-3+2, 5 -2)[/tex]
[tex]\vec C = (-1,3)[/tex]
[tex]\vec D = \vec A + \overrightarrow {AD}[/tex]
[tex]\vec D = (1,7) + (-6,-6)[/tex]
[tex]\vec D = (1-6, 7 -6)[/tex]
[tex]\vec D = (-5, 1)[/tex]
The coordinates of C and D are (1, 3) and (-5, 1), respectivelly.
The legend on a map states that
1 cm is 50 km. If you measure 9 cm
on the map, how many kilometers
would the actual distance be?
Actual distance = [? ] km
Answer:
450 km
Step-by-step explanation:
You simply multiply 9 by 50 to get 450
Answer: 450 km.
Step-by-step explanation: To find the answer to this question, you have to use unit multipliers. We know that 1 cm on the map is 50 km in real life so we multiply 50 km / 1 cm by 9 cm. This cancels out the cm, making km the units. 50*9 = 450, so the answer is 450 km.

The actual product is less than the estimate. The numbers differ by more than one. The actual product is greater than the estimate. The numbers differ by more than one.
Answer:
- The actual product is less than the estimate
- The numbers differ by less than one
Step-by-step explanation:
Given
Product of 3 and two-fifths & [tex]-3\frac{7}{8}[/tex]
Required
Compare actual result with approximated result
Calculating the actual result;
3 and two-fifths means [tex]3\frac{2}{5}[/tex]
So, the Product of 3 and two-fifths & [tex]-3\frac{7}{8}[/tex] becomes
[tex]Product = 3\frac{2}{5} * -3\frac{7}{8}[/tex]
Convert fractions to improper
[tex]Product = \frac{17}{5} * -\frac{31}{8}[/tex]
Combine fractions to form one
[tex]Product = \frac{-17 * 31}{5 * 8}[/tex]
Multiply numerators and denominator
[tex]Product = \frac{-527}{40}[/tex]
Convert fraction to decimal
[tex]Product = -13.175[/tex]
The nearest half of -13.175 is -13
Hence;
[tex]Estimate = -13[/tex]
By comparison:-
- The actual product (-13.175) is less than the estimate (-13)
- The difference between both results is less than 1;
The difference is calculated as follows
Difference = |Actual Product - Estimate|
Difference = |-13.175 - (-13)|
Difference = |-13.175 +13|
Difference = |-0.175|
Difference = 0.175
