enter your response here square feet
(Simplify your answer.)
(a) Christine will decompose the shape into 2 trapezoid
(b) Christine will need 29 square feet area of carpet
How to evaluate for the area of the trapezoid.area of the trapezoid is calculated using the formula: 1/2 × (AB + CD) × height, where AB and CD are the lengths of its parallel sides.
(a). The shape will be decomposed into two (2) trapezoid
(b). For the bigger trapezoid;
8ft 6in = 8.5 ft
area of bigger trapezoid = 1/2 × (8.5 + 12) × 2 ft²
area of bigger trapezoid = 20.5 ft²
For the smaller trapezoid;
2ft 6in = 2.5 ft
area of smaller trapezoid = 1/2 × (2.5 + 6) × 2 ft²
area of smaller trapezoid = 8.5 ft²
Total square feet area of carpet = 20.5 ft² + 8.5 ft²
Total square feet area of carpet = 29 ft²
Therefore, (a) Christine will decompose the shape into 2 trapezoid
(b) Christine will need 29 square feet area of carpet

Calculate (6.25 x 10^9) − (3.44 x 10^8). NEED HELP ASAP WILL GIVE BRAINLIST Step by Step needed
5.906 x 10^9
5.906 x 10^8
2.81 x 10^9
2.81 x 10^1
Answer:
5.906 x 10^9
Step-by-step explanation:
(6.25 x 10^9) − (3.44 x 10^8).
step 1: make the exponents have common value
Move decimal point of 3.44 to the left once and add 1 to it's exponents.
that is 3.44 x10^8 becomes 0.344 x 10^9
= 6.25 x 10^9 - 3.44 x 10^8
= 6.25 x 10^9 - 0.344 x 10^9
step 2: bring out the common factor 10^9 since the exponents are the same.
Also, subtract the decimal numbers.
= (6.25 -0.344) 10^9
6.25 - 0.344 = 5.906
Therefore, the result is 5.906 x 10^9.

Today is Maria's birthday. She is 7 years old. How old is Maria in months?
Answer:
84 months
Step-by-step explanation:
Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.
12 * 7 = 84
Maria is 84 months old
Answer:
Maria is 84 months old.
Multiply the years(y) by every 12 months that pass(m).
\(y * m = 84\)
note that y is 7, and m is 12, because we count every 12 months that pass for 7 years.

Hope you could get an idea from here.
Doubt clarification - use comment section.
Answer:
Hey mate!
Step-by-step explanation:
Lets take two places _ _
Now first position is filled in 4 ways (can use 2 3 7 9) that implies 4C1
then second position is filled in 3 ways since for first position we used a digit

I a local store, almonds are sold at a rate of $15 per kg. Write an equation to represent the relationship between the cost, C, in dollars, and the mass, m, in kg
Answer:
C = 15m
Step-by-step explanation:
Since the almonds are $15 per kg, the cost can be represented by 15m, where m is the number of kg.
To create the equation, set this equal to C, the cost in dollars:
C = 15m
So, the equation is C = 15m
Here is an equation to represent the relationship between the cost, C, in dollars, and the mass, m, in kg of almonds sold at a rate of $15 per kg at a local store: C = 15m
The mass of the almonds closely relates to how much they cost. This implies that the price of almonds will rise along with the mass of the nuts. Since the proportionality constant is $15, the price will be $15 for every kilogram of almonds.
Let's use an illustration to try to comprehend this. A 2 kg purchase of almonds will cost $30. Since 2 x 15 = 30, this is the case.

Joseph graphs how much money he makes per hour on his newspaper delivery route. He finds that the graph tends to be linear and draws a line that passes through the points (3,16.5) and (8,44). About how much does he earn per hour?
A. $5.00 C. $6.00
B. $5.50 D. $6.50
The amount of money that Joseph earns in an hour is $5.50.
What is Linear Function?A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables and the exponent of the variable is 1.
Given that the graph of how much money Joseph making per hour on his newspaper delivery route is linear.
If the function is linear, then the slope must be constant.
The graph will be proportional since the amount of money he earns in 0 hour will be 0.
So, the money he makes per hour is equal to the slope of the line.
Slope of a line given two points = Change in y coordinates / Change in x coordinates
Given points (3,16.5) and (8,44).
Slope = (44 - 16.5) / (8 - 3) = 5.5
Hence the amount he earn per hour is $5.50.

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values
