Find the shaded area. Round to the nearest tenth if necessary.
Answers
Answer:
1.) 49.5 mm ^2
2.) 183 in. ^ 2
Step-by-step explanation:
So for number one, it's a very irregular shape, but luckily, we can split it vertically! Into a triangle & a quadrilateral.
The area of the quadrilateral would be
6*7 = 42
The triangle is more difficult, because its not directly given, BUT, we do know that the height would have to be 6 minus 3, and the base would be 12 minus 7... So the equation is
[tex]A = \frac{1}{2} bh\\A = \frac{1}{2}(5)(3)\\A = 7.5[/tex]
Now, the rectangle and the triangle account for the total area in this case, when you add them, you get 49.5 mm ^2
~~~~~~~~
For the second, we have a trapezoid with a triangular cutout, the area of a trapezoid is defined as:
[tex]A = \frac{1}{2} (B1-B2) h[/tex]
Luckliy, none of the numbers of the bases, or height, are hidden. The height is 18, the larger base is 51, and the smaller is 24.
[tex]A = \frac{1}{2} (51-24)18\\A = 243[/tex]
So, the trapezoid area is 243 in ^2. But we aren't done, we still have the triangle! It will be easy though!
Remember, the formula for a triangle is half the base times the height. These numbers are directly given to us!
[tex]A = \frac{1}{2} (12)(9)\\A = 54[/tex]
Now, since the triangle is NOT SHADED, we subtract it's area from the trapezoid's...
[tex]243 - 54 = 183[/tex]
The area is 183 in. ^ 2

Answer:
1)49.5mm ^2.
2)183 in ^2.
Step-by-step explanation:
So for number one it's a very iregular shape,but luckily ,we can slip it vertycally.
6×7=42.
The triangle is more difficult because it's not directly given.

Find the mean and the standard deviation of the data set {5, 8, 1, 2, 10}.
Answers
5 + 8 + 1 + 2 + 10 = 26 (divided by) 5 = 5.2
The mean and the standard deviation of the data set is 5.2 and 3.429.
What is Arithmetic Mean?The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.
We have,
Data: {5, 8, 1, 2, 10}.
So, the mean of data
= (5+ 8 + 1 + 2 +10)/ 5
= 5.2
Then, the Value of Deviations
-0.2, 2.8, -4.2, -3.2, 4.8
So, the variance is
= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5
= 11.76
And, Standard deviation is
= 3.429

-3y - 7.8 = 9.6 solve these equation
Answers
Answer: -5.8
1. Add 7.8 to both sides.
-3y = 9.6 + 7.8
2. Simplify 9.6 + 7.8 to 17.4.
-3y = 17.4
3. Divided both sides by -3.
Y= -17.4/3
4. Simplify 17.4/3 to 5.8.
Y= -5.8
A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees and totaled $411
Answers
Answer:
Cost of 1 bushes = a = $9
Cost of 1 tree = b = $73.5
Step-by-step explanation:
Given:
13 bushes and 4 trees cost = $411
Missing;
6 bushes and 2 trees cost = $201
Find:
Value of bushes and tree
Computation:
Cost of 1 bushes = a
Cost of 1 tree = b
So,
13a + 4b = 411 ...........eq1
6a + 2b = 201 ................eq2
From Eq1 and Eq2
Cost of 1 bushes = a = $9
From eq 1
13a + 4b = 411
13(9) + 4b = 411
Cost of 1 tree = b = $73.5

5. Write an equivalent expression to 1/4 (24x + 7 – 12x).
Answers
Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses: (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7). This is an acceptable answer. There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.

Answer:
10.3
Step-by-step explanation:
The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.
[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]
We find the square root of both sides to find the value of c.
10.295 ≈ c
Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3

A The cost of living will increase by approximately 1% each year
B The cost of living will decrease by approximately 1% each year
C The cost of living will increase by approximately 5% each year
D The cost of living will decrease by approximately 5% each year
Answers
9514 1404 393
Answer:
C The cost of living will increase by approximately 5% each year
Step-by-step explanation:
If we assume your function is ...
[tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]
Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.
Noah's cost of living is increasing about 5% per year.
