A Skier descended down a mountain at a rate of 14 feet per second.what was his total change in elevation after 8 seconds?
Answer:
1.75ft/s²Step-by-step explanation:
The total change in elevation of the skier is its acceleration. Acceleration is the change in velocity of a body with respect to time.
Acceleration = Velocity/Time
Given velocity of the skier = 14feet/sec
Time taken = 8secs
Acceleration of the skier = 14/8
Acceleration of the skier = 1.75ft/s²
Hence the total change in elevation after 8 seconds is 1.75ft/s²

A bucket of candy contains 24 Jolly Ranchers, 18 Hershey Kisses, 12 packs of Smarties, and some Starburst. The probability of reaching in and pulling out a pack of Smarties is How many Starburst are in the bucket?
Complete question:
A bucket of candy contains 24 Jolly Ranchers, 18 Hershey Kisses, 12 packs of Smarties, and some Starburst. The probability of reaching in and pulling out a pack of Smarties is 1/6.How many Starburst are in the bucket?
Answer:
18
Step-by-step explanation:
Give the following :
Number of jolly ranchers = 24
Number of Hershey kisses = 18
Number of smarties = 12
Number of Starburst = s
Probability of pulling out a smarties ; P(smarties) = 1/6
Probability = required outcomes / total possible outcomes
Required outcome = 12
Total possible outcomes = (24 + 18 + 12 + s) = 54 + s
P(smarties) = 12 / (54 + s)
1/6 = 12 / 54 + s
1 × (54 + s) = 12 × 6
54 + s = 72
s = 72 - 54
s = 18
Hence number of smarties = 18

Answer:
Hey there!
9x-2+2x-8
11x-2-8
11x-10
Let me know if this helps :)
Answer:
11x - 10
Step-by-step explanation:
because there is a plus sign between the brackets, we just assume there are no brackets at all........so it will be:
9x - 2 + 2x - 8,,,,,,,,,bring the like terms together
9x + 2x - 2 - 8 = 11x -10.
the answer has a minus sign because when working out two negative numbers, we add them but still maintain the negative sign.
NOTE: If the sign between the brackets was a minus , the sign in the second expression would have changed from -8 to +8

Kirima is building a wall for her snow fort. She first makes a firm base out of snow, and then piles uniformly sized blocks of snow in a brick-like pattern. She has a maximum height for this wall in mind, and she wants to figure out how many blocks can be stacked vertically in her wall while remaining below this maximum. So, she constructs the expression 0.4x + 0.6 to measure the height of her wall, where all constants represent measurements in meters. Which of the following statements are true? Select all that apply. 0.4 represents the height of the wall. 0.4 represents the height of the base. 0.4 represents the height of each block. 0.6 represents the height of the wall. 0.6 represents the height of the base. 0.6 represents the height of each block.
Answer:
The correct options are;
0.4 represents the height of each block
0.6 represents the height of the base
Step-by-step explanation:
The given information are;
The activity Kirima is engaged in = Building a wall
The process by which she is building the wall includes
1) Construction of a base on the floor
2) Piling blocks of uniform height to form the wall
3) Estimating the height of the wall she is constructing with the expression 0.4·x + 0.6 where the constants which are 0.4 and 0.6 are in meters;
From her procedure, we have the constants, which are the values that do not change as follows;
1) The firm base
2) The uniformly sized blocks
Of the two constants, the one that consists of multiple items is the uniform sized blocks as they are laid in brick pattern
There is only one firm base
Therefore, the constant that has a variable is the uniform sized blocks
Which gives in the expression 0.4·x + 0.6, we have;
0.4 = The dimension of the uniform sized blocks
∴ 0.6 = The dimension of the firm base.

Step-by-step explanation:
(x+3)(x+3) is the x-intercepts of the parabola.
x+3=0 is how to determine the x-intercept.
x= -3
Since both of them are -3, the graph would be A, because the part where the graph touches the x axis is -3.
Solve for x in the diagram below
Answer:
x = 12°Step-by-step explanation:
First of all the angles lie on a right angle which means that they are complementary.
Complementary angles are angles that add up to 90°
To find x add up all the angles and equate it to 90° and solve for x
We have
x + 42 + 3x = 90
4x + 42 = 90
Subtract 42 from both sides
4x + 42 - 42 = 90 - 42
4x = 48
Divide both sides by 4
That's
[tex] \frac{4x}{4} = \frac{48}{4} [/tex]We have the final answer as
x = 12°Hope this helps you

Step-by-step explanation:
During harvesting season at Florida Blue Farms, hand pickers
collect about 200 pounds of blueberries per day with a 95%
pack-out rate. The blueberry harvester machine collects about
22,000 pounds of blueberries per day with a 90% pack-out rate.
The pack-out rate is the percentage of collected blueberries
that can be packaged to be sold, based on Florida Blue Farms'
quality standards.
Let h represent the number of days the hand pickers work and
m represent the number of days the harvester machine is used.
Which of the following algebraic expressions can be used to
estimate the amount of collected blueberries that are packed at
the Florida Blue Farms for fresh consumption this season?
A (0.95h+200)(0.90+22000)
B 0.95(200h)+0.90(22000m)
C 200.95h+22000.90m
D (200h+0.95)(22000m+0.90)
Step-by-step explanation:
its b..........
Bbbbb
The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is: [tex]0.95(200h) + 0.90(22000m)[/tex]
Given that
[tex]h \to[/tex] days of hand pickers word
[tex]m \to[/tex] days harvester machine is used
[tex]n_h = 200[/tex] --- pounds of hand pickers
[tex]n_m = 22000[/tex] -- pounds of harvester
[tex]r_h = 95\%[/tex] -- pack out rate of hand pickers
[tex]r_m = 90\%[/tex] -- pack out rate of harvester
The expression to estimate the amount is calculated as:
[tex]Amount = r_h \times n_h + r_m \times n_m[/tex] --- i.e. pounds of hand picker * its pack out rate + pounds of harvester * its pack out rate
So, we have:
[tex]Amount = 95\% \times 200h + 90\% \times 22000m[/tex]
Express as decimal
[tex]Amount = 0.95 \times 200h + 0.90 \times 22000m[/tex]
Rewrite as:
[tex]Amount = 0.95(200h) + 0.90(22000m)[/tex]
Hence, option (b) is correct.

Answer:
The angle of PML is 68°.
Step-by-step explanation:
Given that total angles in a straight line is 180° so we can assume that ∠LMN is 180°. In order to find ∠PML, we have to subtract :
[tex]∠PML+∠ PMO + ∠OMN = 180[/tex]
[tex]∠PML + 90 + 22 = 180[/tex]
[tex]∠PML + 112 = 180[/tex]
[tex]∠PML = 180 - 112[/tex]

-240/ -15 = 16A baby weighs 115 ounces. What is the baby's weight in pounds and ounces? *Plz explain your answer*
Answer:
7 pounds 3 ounces
Step-by-step explanation:
There are 16 ounces in a pound. In order to convert ounces to pounds, we need to see how many 16s fit into 115 (how many full pounds can be made with 115 ounces) and add the remainder as ounces. To do this we can do long division (which gives us 7 remainder 3), or we can divide 115 by 16 (=7.1875) and convert the decimal places to ounces by multiplying 0.1875 pounds (the remainder) by 16 (as there are 16 ounces in pound) which gives us 3 ounces.
So 115 ounces is equal to 7 pounds and 3 ounces.
Hope this helped!
The baby's weight is 7 pounds and 3 ounces.
To convert ounces to pounds, we need to divide the number of ounces by the conversion factor, which is 16. There are 16 ounces in 1 pound.
Let's denote the baby's weight in ounces as W oz, the weight in pounds as W lb, and the remaining ounces as Roz.
W oz = 115 ounces
W lb = ?
R oz = ?
First, we divide the total number of ounces by 16 to find the number of pounds:
W lb = W oz / 16
= 115/ 16
= 7.1875 pounds
So, the baby weighs 7 pounds.
To determine the remaining ounces, we multiply the decimal portion of the pounds (0.1875) by 16:
R oz = 0.1875 x 6
R oz= 3 ounce
So, the baby weighs an additional 3 ounces.
Therefore, the baby's weight is 7 pounds and 3 ounces.
