Emma wants to stain a circular deck that has a diameter of 12 m. The cost of the wood stain is $3.25
per square meter.
To the nearest dollar, how much will it cost Emma to stain the entire deck?
Use 3.14 for
Answer:
$1469
Step-by-step explanation:
diameter of deck = 12 m
diameter = 2*radius
thus
12 m = 2*radius
radius = 12m / 2 = 6 m
area of circle is given by [tex]\pi r^{2}[/tex]
where r is the radius
thus, area of given deck with radius = 12 m
[tex]\pi r^{2} = 3.14*12^{2} \\=> 3.14*144 = 452.16[/tex]
Thus, area of given deck is 452.16 meter square
given
The cost of the wood stain is $3.25 per square meter
cost of 1 meter square wood stain = $3.25
since we have to find to stain the entire deck which has area 452.16 meter square , we multiply both side of equation by 452.16
cost of 452.16 meter square wood stain = $3.25*452.16 = $1469.25
Thus,
it will cost $1469 to the nearest dollar for Emma to stain the entire deck

Solve for x and y in the diagrams below.
1. x = 13, y = 11.5
2. x = 39, y = 123
Step-By-Step Explanation: For the first diagram, you can see that 10x - 42 = 6x + 10 by way of vertical angles. Vertical angles are two opposite angles created by the same two lines, meaning that they will ALWAYS be congruent. Solving for x, you get that 4x = 52, or that x = 13. There is another thing. Both of the diagrams have a total angle measurement of 360, since they both go all the way around. Knowing that, 6x + 10 + 8y must be equal to half of that, or 180. Solving for 88 + 8y = 180 (since you know the value of x), you know that 8y = 92, or x = 11.5.
For number two, the concept is very similar, but this time there's more angles. You can immediately see that there are 3 pairs of vertical angles. The value of the angle squishes between the x - 10 and the 3x + 6 is x - 11; again, vertical angles. The angle squished between 3x + 6 and x - 11 is x - 10 (vertical angles!). Last, you know that 3 x + 6 = y, since they are vertical angles. Combining 2(x-11) and 2(x-10) and 2(3x+6) [remember, y = 3x + 6!!], you get that 10 x = 390, and x = 39. Plug that in for the value of y, which is 3x + 6, giving you 123 degrees.

Step-by-step explanation:
hope this helps :)
Answer:
-19/3
3x-1/4 = -5
3/4x + -1/4 = -5
+1/4 +1/4
1x = -19/4
multiply both sides by 4/3
x = -19/3

Answer:
Y intercept would be (0, 2/3)
Step-by-step explanation:
Answer:
the y intercept is 2/3
Step-by-step explanation:
The equation is in slope intercept form y = mx+b where m is the slope and b is the y intercept
y = -9/7x + 2/3
The slope is -9/7 and the y intercept is 2/3
using your value of x from question #11, find the measure of angle h .none of this makes any sense to me at all so if y'all get it right amen will mark brainiest this is so hard ty so much
Answer:
∠H = 58Step-by-step explanation:
using the value of x = 20 from number 11
solve the angle H
∠H = 3x - 2
plugin the value of x=20 into the equation
∠H = 3(20) - 2
∠H = 58

(-4b2+8b)+(4b3+5b2-8b)=
The solution of the expression (- 4b² + 8b) + (4b³ + 5b² - 8b) would be
(4b³ + b² ).
Used the concept of the equation that states that,
An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that,
The equation is,
(- 4b² + 8b) + (4b³ + 5b² - 8b)
Now, combine like terms of the equation and simplify as,
(- 4b² + 8b) + (4b³ + 5b² - 8b)
4b³ - 4b² + 5b² + 8b - 8b
4b³ + b²
Therefore, the solution is (4b³ + b² ).

Jenny has only 3 1/2 cups of flour in her house. She needs 1 5/8 cups for a brownie recipe. Her sister Jody needs 1 3/4 cup flour for her cookie recipe. Will there be enough flour for both recipes?
Answer:
yes, Jenny has enough flour for both recipes
Step-by-step explanation:
First, find what Jody and Jenny need for both their recipes. For this, we need a common denominator, 8
1 5/8=13/8
3/4=6/8
13/8+6/8=19/8
Jody has 3 1/2 cups of flour, which is 7/2 cups or 28/8.
Now we need to make sure that 28/8 is greater than 19/8
28>9.... so she has enough flour!

Answer:
Shown below.
Step-by-step explanation:
The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:
Number: 0 1 2 3 4 5 6 7 8 11 12
Frequency: 5 16 20 14 3 5 4 4 2 1 1
The probability of an events, say E is the ratio of the number of favorable outcomes to the total number of outcomes.
[tex]P(E)=\frac{n(E)}{N}[/tex]
Compute the probabilities of 0 - 12 hurricanes each season as follows:
Number Frequency Probability
0 5 0.07
1 16 0.21
2 20 0.27
3 14 0.19
4 3 0.04

Which of the following is not equal to the rational number 7/4 ?
Option 1: 14/8
Option 2: 10/7
Option 3: 1.75
Option 4: 1 3/4
YOU COULD PICK MORE THEN ONE OPTION
Answer:
(2) [tex] \frac{10}{7} [/tex]
Step-by-step explanation:
Given the rational number, [tex] \frac{7}{4} [/tex], the following can be said to be equal to the rational number:
1. [tex] \frac{14}{8} [/tex]
Simplify the fraction
[tex] \frac{2*7}{2*4} [/tex]
[tex] = \frac{7}{4} [/tex]
Therefore, [tex] \frac{14}{8} = \frac{7}{4} [/tex]
3. [tex] \frac{7}{4} = 1.75 [/tex] (using your calculator)
4. [tex] 1\frac{3}{4} [/tex]
Convert from mixed fraction to improper fraction
[tex] 1\frac{3}{4} = \frac{7}{4} [/tex]
[tex] \frac{10}{7} [/tex] ≠ [tex] \frac{7}{4} [/tex]
The answer is (2) [tex] \frac{10}{7} [/tex]
