plz help find the area asap i really need help with the math problems
for the third picture Copy the problem, mark the givens in the diagram, and write a Statement/Reason proof. Given: CN = WN, ∠C ≅ ∠W Prove: RN ≅ ON
Answer:
uh the area is 45 for the first one because 15*9 is 135 and 15*6 is 90 because you get 6 from 15-9 to get the length for the triangle. Then 135-90 is 45.
Step-by-step explanation:
The area for the second shape is 114 because you will take 14 multiplied by 12 and you get 168, then you will take 6*9 which is 54 and subtract that from 168, and you should get 114.
The area for the third shape is i dont even know because it doesnt give numbers unless your trying to find it with the letters but at least you got the first two

Answer:
16.2 feet
Step-by-step explanation:
Reference angle = 62°
Opposite = x
Adjacent = 8.6
Apply trigonometric function, TOA:
Tan 62 = Opp/Adj
Tan 62 = x/8.6
8.6 × Tan 62 = x
16.1742476 = x
x = 16.2 ft (nearest tenth)

Step-by-step explanation:
A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 11 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 53 bolts. The sample mean bolt length was 11.08 centimeters. The population standard deviation is known to be 0.21 centimeters.
What is the test statistic?
What is the -value?
Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of 0.01?
Using the t-distribution, it is found that:
The test statistic is t = 2.77.The p-value is of 0.0039.Since the p-value is less than 0.01, sufficient evidence exists that the length of bolts is actually greater than the mean value at a significance level of 0.01.What are the hypotheses tested?At the null hypotheses, it is tested if the mean is of 11 cm, that is:
[tex]H_0: \mu = 11[/tex]
At the alternative hypotheses, it is tested if the mean is greater than 11 cm, hence:
[tex]H_1: \mu > 11[/tex].
What is the test statistic?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.For this problem, the values of the parameters are given as follows:
[tex]\overline{x} = 11.08, \mu = 11, s = 0.21, n = 53[/tex]
Hence the value of the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{11.08 - 11}{\frac{0.21}{\sqrt{53}}}[/tex]
t = 2.77.
Using a calculator, with t = 2.77 and 53 - 1 = 52 df, the p-value is of 0.0039.
Since the p-value is less than 0.01, sufficient evidence exists that the length of bolts is actually greater than the mean value at a significance level of 0.01.

Mrs. Via needs to buy
grass seed for her yard. She drew a diagram
of her yard. Each square represents 1 square
yard. Five pounds of seed is enough to plant
100 square yards of grass. Grass seed is sold in
2-pound bags. How many bags of grass seed
does Mrs. Via need?
Answer:
Step-by-step explanation:
Via needs 2 1/2 bags of grass seed
The number of bags of grass seed that Amanda should use to spread her yard is 16.65 bags, meaning she needs to buy not more than 17 bags, using mathematical operations.
What are mathematical operations?The basic mathematical operations we use are subtraction, addition, division, and multiplication.
In this situation, we use the division operation.
The division operation involves four parts:
The dividend (numerator or the number being divided).
The divisor (denominator or the number dividing).
The quotient (the result of the division operation).
The equal symbol (that shows that two values are equal).
The area of the yard = 4,995 ft²
1 yard = 3 feet
Area of the yard = 1,665 square yards(4,995/3)
The number of bags per 100 square yards = 1 bag
For 1,665 square, the number of bags = 16.65 bags (1,665 ÷ 100)
Thus, Amanda requires 16.65 bags of the grass seed for her yard.

Step-by-step explanation:
Jessie bought 12 cases of soda for the party. If his total bill was $41.40, how much did each case cost?
Answer:
B. $3.45
Step-by-step explanation:
Number of cases of soda bought = 12
Total bill payed = $41.40
Let x represent the cost of 1 case.
Thus:
12x = $41.40
Divide both sides by 12
12x/12 = 41.40/12
x = 3.45
Cost of each case = x = $3.45
Write an equation of the line that passes through a pair of points:
(-5, - 2), (4, 5)
Answer (assuming it can be written in slope-intercept form):
[tex]y = \frac{7}{9} x+\frac{17}{9}[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(5)-(-2)}{(4)-(-5)} \\m = \frac{5+2}{4+5} \\m = \frac{7}{9}[/tex]
So, the slope is [tex]\frac{7}{9}[/tex].
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{7}{9}[/tex] for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form ([tex]y = mx + b[/tex] format) and find the following answer:
[tex]y-(5) = \frac{7}{9} (x-(4))\\y-5 = \frac{7}{9} (x-4)\\y -5=\frac{7}{9} x-\frac{28}{9}\\y = \frac{7}{9} x-\frac{28}{9} +\frac{45}{9}\\y = \frac{7}{9} x+\frac{17}{9}[/tex]

Question 27
27. If an increase in one quantity brings about a corresponding decrease in the
other and vice versa, then the two quantities vary
a) sometimes directly and sometimes inversely b) directly
c) inversely d) none of these
ОА
Ов
Ос
OD
Answer:
c) inversely
Step-by-step explanation:
In Mathematics an inverse relationship can be defined as a relationship between two variables, in which an increase in the value of one variable leads to a decrease in the value of the other variable i.e as the value of one variable becomes large, the value of the other variable becomes small.
Mathematically, an inverse relationship is given by the formula;
A = K/B
Where;
A and B are the variables.
K is the constant of proportionality.
Hence, if an increase in one quantity brings about a corresponding decrease in the other and vice versa, then the two quantities vary inversely.

What is the answer for 5 × (-2w - 4)
Answer: -10w-20
Step-by-step explanation:
Because the number is in front of the bracket you have to times everything inside the bracket by the number on the outside.
5x-2w= -10w (you would basically do 5x-2 which is -10 then put the w on the end of it).
5x-4= -20
Then put it together so -10w-20

a man gets $312 for working 48 hours a week. how much does he get when he works 36 hours a week?
Answer:
$234
Step-by-step explanation:
Create a proportion where x is the amount he gets working 36 hours
[tex]\frac{312}{48}[/tex] = [tex]\frac{x}{36}[/tex]
Cross multiply and solve for x
48x = 11232
x = 234
So, when he works 36 hours a week, he will get paid $234
Answer:
assuming he is paid hourly?
312÷48= 6.50/hour
so, 6.50÷36= $234
