The area of a triangle is 838. Two of the side lengths are 63 and 29 and the included
angle is obtuse. Find the measure of the included angle, to the nearest tenth of a
degree.

Answer:

$8.88

Step-by-step explanation:

5.50+5.50+3.75+3.00=17.75÷2=8.88

Answer:

Its A.

Step-by-step explanation:

Add the price up to find the total: 5.50 + 3.75 + 3 = $12.25. Since there were 2 people and they wanted to split the cost- they pay half half. So 12.25 divided by 2 is $6.12.5 but you gotta round it to get an answer hats there so you round it up to 6.13.

Answer: 75%

Step-by-step explanation:

20+20+25+3+2+5=75

Total of 100 students

75/100=0.75

=75%

 The percentage of P(sports ∪ work) is equal to  75%.

We have given the table

we have to find the percentage of sports and work

Total=Work+sports

Therefore we have to add the values of work and sports

20+20+25+3+2+5=75

Total of 100 students

75/100=0.75

=75%

Therefore the percentage of P(sports ∪ work) is given by 75%.

x>1

Step-by-step explanation:

21-7x>14

-7x>-7

x>1

Answer:

x<1

Step-by-step explanation:

7(3-x)>14

21-7x>14

-7x>-7

x<1

as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.

[tex]\stackrel{f(x)}{y}~~ = ~~\cfrac{4x}{x-9}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{4y}{y-9}}\implies xy-9x=4y\implies -9x=4y-xy \\\\\\ -9x=y(4-x)\implies \cfrac{-9x}{4-x}=y\implies \cfrac{9x}{x-4}=\stackrel{f^{-1}(x)}{y}[/tex]

how to test algebraically? well, for any (a,b) pair in f(x), its inverse will have another pair but (b,a), hmmm let's plug hmmm say

f(10) = 40, and f⁻¹(40) = 10.

we could plug more values in each, same pair will come up.

as far as testing them graphically, Check the picture below.

Formula for circumference;

C = 2πr

replace those values

C = 2 x 3.14 x 9

C = 56.52 inches, C

Answer:

The circumference would be 56.52

Step-by-step explanation:

Place your radius into the formula for circumference (C=2πr)

C = 2 × 3.14 × 9

C = 56.52

Answer:

The coordinates of the points on the unit circle help us to find the tangent of each angle. As you can see with this equation, the tangent of an angle is equal to the y-coordinate divided by the x-coordinate. For each angle, start by dividing each y-coordinate by the x-coordinate to get the tangent of that angle.

Answer:

Step-by-step explanation:

Given the equation for the object's height s at time t seconds after launch is

s(t) = -4.9t^2 + 18.4t + 36.8

Since are not asked what to look for, we can as well lok for the time taken for the ball to hot the ground. The ball hits the ground at when s(t) = 0. The equaton becomes:

0 = -4.9t^2 + 18.4t + 36.8

Multiply through by -10

49t^2 - 184t - 368 = 0

factorize the resulting expression

t = 18±√184²-4(49)(-386)/2(49)

t =  18±√338564+75656/78

t =  18±√414220/78

t =  18±643.599/78

t =  661.559/78

t = 8.48secs

Hence the object reaches that ground after 8.48seconds

Answer:

Patrick's statement is incorrect

Step-by-step explanation:

Crackers come in packages of 24

cheese slices come in packages of 18

He wants one cheese slice for each cracker

Patrick made the statement below "if Andy doesn't want any crackers or cheese slices left over he needs to buy at least 432 of each"

Patrick's statement is incorrect

The lowest common multiple ( L. C. M) of 24 and 18 is 72

Therefore, Andy needs 72 packages of crackers and 72 packages of cheese slice so that no crackers or cheese slice will remain.

Answer:75/6

Step-by-step explanation: Y is proportional to x so 12 is proportional to 5 so if y=30 then it will be 30*5/12=150/12=75/6

Answer: see below

Step-by-step explanation:

Hypothesis (p): A triangle is equilateral

Conclusion (q): The side lengths are equal

Conditional (p → q): If a triangle is equilateral, then its side lengths are equal.

The conditional statement is TRUE

Converse (q → p): If the side lengths of a triangle are equal, then it is equilateral.

The converse statement is TRUE

Since p → q   and  q → p are both TRUE, then it is biconditional.

Using proportions, it is found that a tree that casts a shadow 4 ft long is 180 in. tall.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, a fire hydrant that is 30 in. tall and casts a shadow 8 in. long. We want to find the height of a tree that casts a shadow of 4 ft = 4 x 12 = 48 inches. Hence, the rule of three is given by:

30 in - 8 in

h in - 48 in

Applying cross multiplication:

h = 48 x 30/8

h = 6 x 30.

h = 180 in.

Answer:

B both are proportional

Step-by-step explanation:

so i think by proportional its linear?

so the graph is linear because its a line and its a function, but for the table we first have to find the slope by using the equation

y2 - y1 / x2 - x1

(4, 1.31) and (8, 2.62) will be the points we will use

2.62 - 1.31 / 8 - 4

1.31/4

0.3275x

now i think we use a point we did not use yet sooo (16, 5.24)

we substitute

y = 0.3275x + b

5.24 = 0.3275(16) + b

5.24 = 5.24 + b

b = 0

so the equation would be

y = 0.3275x

now we check with the last point given

6.55 = 0.3275(20) ?

6.55 = 6.55

so i think the answer is both are proportional ?
