Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.
Part A= 12 x ? = ? ft²
Part B= 0.5 x ? x 9 = ?ft²
Part C= 0.5 x 7 x ? = ?ft²
Total Area= ?ft²
Answer:
[tex]A = 108ft^2[/tex]
[tex]B = 27ft^2[/tex]
[tex]C = 24.5ft^2[/tex]
[tex]Area = 159.50ft^2[/tex]
Step-by-step explanation:
Given
See attachment
From the attachment;
Part A is a rectangle with dimension 9ft by 12ft
So,
[tex]A = 12ft * 9ft[/tex]
[tex]A = 108ft^2[/tex]
Part B is a triangle with dimension: height = 6 and base = 9
The height is calculated as:
[tex]Height = 12ft - 6ft = 6ft[/tex]
And the base is:
[tex]Base = 18ft - 9ft = 9ft[/tex]
So, the area is:
[tex]B = 0.5 * 6ft * 9ft[/tex]
[tex]B = 27ft^2[/tex]
Part C is a triangle with dimension: height = 7 and base = 7
So, the area is:
[tex]C = 0.5 * 7 * 7ft^2[/tex]
[tex]C = 24.5ft^2[/tex]
Total Area is:
[tex]Area = A + B + C[/tex]
[tex]Area = 108ft^2 + 27ft^2 + 24.5ft^2[/tex]
[tex]Area = 159.50ft^2[/tex]
Using the same triangle as above, calculate the area of the triangle. You must show TWO methods for calculating the area of the triangle. Round both answers to nearest tenth. Hint: you should be using the same values you provided in question 3 and you can use any values you calculated in question 3 as well.
Answer:
Step-by-step explanation:
Area of a triangle is 1/2 * b * h
b = base, the one labeled b on the diagram
h = height, the dotted line in the middle
so, you do pythagorean theorem with a and b to find the dotted line
a² + b² = h² (h is for height)
h = [tex]\sqrt{a^{2} +b^{2}}[/tex]
Then, you just plug in the numbers from question 3 to find h and then you do
1/2 * b * h

In Mr. Walker's 7th grade class, the 30 students created a pie chart showing their choices for favorite pet. Based on the class findings, how many students chose cat as their favorite pet? Explain.
A) 6
B) 10
C) 3
D) 9
Answer:
D - 9 students
Step-by-step explanation:
For this problem, you need to find the percentage of students left. Subtracting all the percentages you already know, you get 100 - 30 - 20 - 10 - 10, or 30. Since there are 30 students in the class, 30 percent of 30 is 9 students.

Nancy joined a school band .she bought 4 violins at 87.82 per violin and 2 song books
which were 7.96 each with 4 100 bills. how much change was Nancy given?
Answer:
$32.80
Step-by-step explanation:
Find out how much Nancy spent on 4 violins and 2 song books.
1 violin = 87.82
4 violins = 87.82 x 4 = 351.28
1 song book = 7.96
2 song books = 7.96 x 2 = 15.92
351.28 + 15.92 = 367.20
4 x 100 dollar bills = 400 dollars
Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.
400 - 367.20 = 32.80

somebody please help quick! solve for x
Answer:
x = 8
Step-by-step explanation:
51° = 4x + 19
32° = 4x
8 = x
Answer:
x = 8
Step-by-step explanation:
well, 4 x something + 19 = 51
51-19=32
32/4=8
so your answer is 8
4 x 8 + 19 = 51
how do you calculate the standard error of the mean in SPSS?
Answer:
Hope this helps
Step-by-step explanation:
Std Error Mean – Standard Error Mean is the estimated standard deviation of the sample mean. This value is estimated as the standard deviation of one sample divided by the square root of sample size: 9.47859/sqrt(200) = . 67024, 10.25294/sqrt(200) = . 72499.

Given the function C(t) = (t - 2)(t + 6) (t - 4):
the coordinates of its C-intercept are
the coordinates of its t-intercepts are
Answer:
c*(t)-((t-2)*(t+6)*(t-4))=0
Step-by-step explanation:
ct - ((t - 2) • (t + 6) • (t - 4)) = 0
ct - (t - 2) • (t + 6) • (t - 4) = 0
3.1 ct-t3+28t-48 is not a perfect cube
ct - t3 + 28t - 48 = 0
Solve ct-t3+28t-48 = 0

please help me i really need help please
Answer:
104
Step-by-step explanation:
Hey There!
So essentially what this problem is asking us to do is solve for the missing angle in a triangle
Remember all of the angles in a triangle will add up to 180
so to find the missing angle we subtract the given angles (38 and 38) from 180
180-38-38=104
so we can conclude that angle A equals 104

In a recent Super Bowl, a TV network predicted that 25 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 150 people who saw the commercials and found that 30 of them said they would watch one of the television shows. Suppose you have the following null and alternative hypotheses for a test you are running:
H0:p=0.53H0:p=0.53
Ha:p≠0.53Ha:p≠0.53Calculate the test statistic.
Answer:
The right solution is "-8.25".
Step-by-step explanation:
The given values are:
Sampled people,
n = 150
Null and alternative hypotheses will be:
[tex]H_0:p=0.53[/tex]
[tex]Ha:p\neq 0.53[/tex]
The z-statistics will be:
⇒ [tex]z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }[/tex]
On substituting the values, we get
⇒ [tex]=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }[/tex]
⇒ [tex]=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }[/tex]
⇒ [tex]=\frac{-0.33}{0.04}[/tex]
⇒ [tex]=-8.25[/tex]

Answer:
x = 5 / 3 = 1.667
Step-by-step explanation:
8*x+10-5*x-(15)=0
Solve : 3x-5 = 0
Add 5 to both sides of the equation :
3x = 5
Divide both sides of the equation by 3:
x = 5/3 = 1.667
x = 5/3 = 1.667
