Answer:
C. 52.5cm^2
Step-by-step explanation:
Area of a triangle - A=1/2bh or area=1/2 base times height
Area of a rectangle - A=lw or area=length times width
Separate the shapes first, you would draw a line between the two if this was on paper.
Find the separate areas.
Rectangle area:
8*5=40
Triangle area:
find the height first. the height of this triangle is the same as the length of the rectangle minus the 1 and 2 cms.
8-1-2=5
1/2*5*5=12.5
Now add the areas:
40+12.5=52.5cm^2

When the light turns green, John accelerates straight down the road at 1.8 m/s for 8 seconds. What is his final velocity at the end of those 8 seconds
Answers
Acceleration is the rate of change of velocity over time
His final velocity is 14.4 meters per second
How to determine the final velocityFrom the question, we have:
Initial velocity: u = 0 m/sTime = 8 secondsAcceleration = 1.8 m/s^2Using the first equation of motion, we have:
[tex]v = u + at[/tex]
So, the equation becomes
[tex]v = 0 + 1.8 * 8[/tex]
[tex]v =14.4[/tex]
Hence, the final velocity is 14.4 meters per second

A rectangular room has a width 1.6 times its length, and its perimeter is 26 meters. Find the dimension of the room, round to the hundredth place.
Answers
Answer:
The dimension of the room is Length of 5m and Width of 8m
Step-by-step explanation:
Formula for perimeter of a rectangle is;
P = 2(L + W)
Where;
L is length
W is width
We are given;
Width; W = 1.6L
Perimeter; P = 26 m
Thus;
2(1.6L + L) = 26
2(2.6L) = 26
5.2L = 26
L = 26/5.2
L = 5 m
W = 1.6 * 5
W = 8 m
A researcher measures the amount of food consumed by each dog in her lab. She finds that the mean amount eaten by the 10 dogs is 14 oz. The sum of squared deviations is 220. What is the variance for this data set
Answers
Using statistical concepts, it is found that the variance for this data set is of 22 oz squared.
What are the mean and the variance of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The variance of a data-set is given by the sum of the differences squared between each observation and the mean, divided by the number of values.
From the second bullet point, the variance can also be interpreted as the sum of squared deviations divided by the sample size.
In this problem, the sum of squared deviations is 220 and the sample size is 10, hence, the variance for this data set is of 22 oz squared.

Alex has been studying for the certified management exam. Results from the last exam indicate that the mean was 62 with a standard deviation of 6. He needs to be in the top 20% (80th percentile) to pass. Use z value with two decimal places, 1.28, in your calculations. What score will place Alex in the top 20% of the distribution
Answers
Alex needs a score of about 70 to be in the top 20% of the distribution
Z scoreThe z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ)/σ
Where x is raw score, μ is mean and σ is standard deviation.
Given that μ = 62, σ = 6, z = 1.28, hence:
1.28 = (x - 62) / 6
x = 69.68
Alex needs a score of about 70 to be in the top 20% of the distribution

About 718.0133 cm³
Step-by-step explanation:
The crucial part is to take V=4/3πr³ and multiply that by 1/2 (or divide by 2) This is because it is asking for half a sphere, which represents a bowl.
You plug in your values, which will look like: (1/2)(4/3)π(7)³. (Remember to insert 7 not 14 since it's asking for radius).
________________________________________________________
7 cubed is 343,
343 * 2/3 is about 228.66

A student bought a sandwich for 80 cents, milk for 20 cents, and a pie for 30 cents. How much did the meal cost?
Answers
[tex]\huge \text{Hello there! :)}[/tex]
Answer:
130 cents, or $1.30.
Step-by-step explanation:
To find the total cost of the meal, add the costs of each product.
Since the cost of the sandwich was 80 cents, the cost of the milk was 20 cents and the cost of the pie was 30 cents, then the total cost of the meal (in cents) is:
[tex]80+20+30[/tex]
Add the numbers from left to right. Since 80+20 is equal to 100, then:
[tex]80+20+30=100+30[/tex]
Finally, notice that 100+30 is equal to 130:
[tex]100+30=130[/tex]
So, the total cost of the meal was 130 cents. Each 100 cents is equal to 1 dollar. Then, 130 cents is the same as $1.30.
Therefore, the cost of the meal was 130 cents, or $1.30.
