Complete question :
The Hiking Club is taking another trip. The hike leader's watch shows that they gained 296 feet in altitude from their starting position. Their altitude is now 285 feet, but there is no record of their starting altitude. Write and solve an equation to represent this situation and find their starting altitude.
Answer:
Expression :
285 = x + 296
Starting altitude, x = - 11 feets
Step-by-step explanation:
Let starting position = x
Altitude gained = 296 feets
Final attitude = 285 feets
The starting altitude could be obtained by the expression :
Final altitude = starting altitude + Altitude gained
285 = x + 296
Solve for x, to obtain starting altitude ;
285 - 296 = x + 296 - 296
-11 = x
Hence, starting altitude is - 11 feets
The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.

Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.
What is the probability of Sarah picking a blue marble on 2 consecutive draws without replacement?
Answer: The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%
Step-by-step explanation:
Given: Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.
The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = [tex]\dfrac{40}{100}\times\dfrac{39}{99}=0.157575757576\approx15.8\%[/tex]
Hence, the probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%

B 67 x 10 4 In.
C 6.7 x 10-4 in.
D 67 x 10-4 in.
Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.

The standard deviation of a population is 4.1.
What is the margin of error?
If the standard deviation of a population is 4.1. The margin of error is 16.81.
Margin of error:Given:
Standard deviation=4.1
Hence:
Variance will be the standard deviation square
Variance=Standard deviation²=4.1×4.1
Variance=Standard deviation²=16.81
So,
Margin of error=16.81
Therefore the margin of error is 16.81.

What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
From the Curve we can write
slope = (101 - 105) / (5- 0)
slope = -4/5
so, the equation to represent the situation is
= -4/5t + 105
= -0.8t + 105
Now, if t= 15 then
s= -12 + 105
s = 93

Which answer describes the sequence {1,3,7,15,…} as a mathematical statement? The nth value equals 1 more than twice the first value. The nth value equals 1 more than twice the previous value. The nth value equals the sum of the previous 3 values. The nth value equals 1 more than the sum of the previous value and n. Checkpoint 04 Click on the numbers to jump from one question to another.
Answer:
Step-by-step explanation:
Each new value is 1 plus twice the previous value.
First value is 1. Then,
1 plus twice 1 = 3, the second value.
Second value is 3
1 plus twice 3 = 7, so
Third value is 7
and so on (this is merely a check)

What is Arithmetic Sequence?An arithmetic sequence is a sequence in which the difference between any two terms of the sequence is the same or equal.
aₙ = a₁ + (n-1)d
where,
aₙ is the nth term of the sequence,
a₁ is the first term of the sequence,
r is a common difference between every two terms.
The arithmetic sequence given is 1,3,7,15,…, therefore, the common difference between the series and the value of the first term can be written as,
d = 3-1 = 2
a₁ =1
the nth term of the series can be defined as the,
aₙ = a₁ + (n-1)d

Step-by-step explanation:
you are a very nice person for helping your mom. good luck for this!
ok let's work on question 7 first.
$63.99 is the cost of a skateboard.
15% of 63.99 = 10% + 5%
10% of 63.99 = 6.399 (move the decimal one place to the left)
5% of 63.99 = 1/2 of 6.399
1/2 x 6.399 = 3.1995
6.399 + 3.1995 = 9.5985
ok, so that's 15% of 63.99
now we need to take away 9.5985 from 63.99
63.99 - 9.5985 = 54.3915
the discount price of the skateboard is $54.3915
a further 10% is $5.43915
so take off that from the discount,
54.3915 - 5.43915 = 48.95235
the final price is $48.95235
QUESTION 8
shop A = 6.95 x 40
6.95 x 40 = $278
shop B = 20% of 325
20/100 * 325 = 65
325 - 65 = 260
therefore, shop B is cheaper.
hope this helped, good luck!
