Solve for a side in right triangles
Answer:
4.50 = ?
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite / hypotenuse
sin 40 = ? / 7
Multiply each side by 7
7 sin 40 = ?
4.499513268 = ?
To the nearest hundredth
4.50 = ?

OD. {{-43, -12), (-3, -3), 4,0), (0, 3), (6,12)}
Answer:
The first set (A)
Step-by-step explanation:
The five inputs are {-12, -3, 0, 3, 12}. The first set (A) includes all five of these inputs and a single output for each of them: {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).
Using the given function, the correct set of ordered pairs for the following domain values is A; {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).
What is the domain and range of the function?The domain of a function is defined as the set of all the possible input values that are valid for the given function. The range of a function is defined as the set of all the possible output values that are valid for the given function.
The five inputs are given as;
{-12, -3, 0, 3, 12}
WE can see that first set (A) includes all five of these inputs and a single output for each of them;
{(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).
Therefore, Using the given function, the correct set of ordered pairs for the following domain values is A; {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Find the equation of the line in slope-intercept form containing the points (6, -1) and (-3, 2). y = - 1/3x + 1 y = -3 x -1 y = 9 x -1 y = 1/3x -1
Answer:
y = - 1/3 x + 1
Step-by-step explanation:
(6, -1) and (-3, 2)
Slope = (y2 - y1)/(x2 - x1) = (2 - (-1))/(-3-6) = 3/(-9) = - (1/3)
y-int form is y = ma +b
y = - 1/3 x +b
(-3, 2)
2 = (- 1/3)*(- 3)+ b
2 = 1 + b
b = 1
y = - 1/3 x + 1

Step-by-step explanation:
Please refer to attached for labeling of the diagram:
We have 2 triangles here in the figure:
[tex]\triangle ABC \text{ and }\triangle BDE[/tex].
1. [tex]\angle B[/tex] is common to both the triangles.
Sides AC || DE (parallel sides):
So, Corresponding angles will be equal
2. [tex]\angle A = \angle D[/tex]
3. [tex]\angle E = \angle C[/tex]
So, [tex]\triangle ABC \text{ and }\triangle BDE[/tex] are similar to each other.
Similar triangles have ratio of their sides as equal.
So, [tex]AB : BD = BC : BE[/tex]
[tex]\Rightarrow \dfrac{6+7}{6} = \dfrac{21}{21-x}\\\Rightarrow \dfrac{13}{6} = \dfrac{21}{21-x}\\\Rightarrow 13 \times (21-x) = 21 \times 6\\\Rightarrow 13x = 7 \times 21\\\Rightarrow x = \dfrac{147}{13}[/tex]
Hence, [tex]x = \dfrac{147}{13}[/tex]
AC=A, C, equals
Round your answer to the nearest hundredth.
Answer:
We have the equation A*C = A
Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.
We can divide both sides by A and get:
(A*C)/A = A/A
C = 1
So here we finded the value of A.
If A and C are matrices, then C is the identity matrix.

Find the value of k so that x = -1 and y =-1 is a solution of the linear equation 9kx + 12ky = 63
Answer:
k = - 3
Step-by-step explanation:
Given
9kx + 12ky = 63
Since x = - 1 and y = - 1 are solutions of the equation
Substitute x = - 1 and y = - 1 into the equation and solve for k
9k(- 1) + 12k(- 1) = 63, that is
- 9k - 12k = 63
- 21k = 63 ( divide both sides by - 21 )
k = - 3

The area of a square is (16x2 − 8x + 1) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work.
Answer:
4x - 1
Step-by-step explanation:
Given the area
16x² - 8x + 1
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 16 × 1 = 16 and sum = - 8
The factors are - 4 and - 4
Use these factors to split the x- term
16x² - 4x - 4x + 1 ( factor the first/second and third/fourth terms )
= 4x(4x - 1) - 1(4x - 1) ← factor out (4x - 1) from each term
= (4x - 1)(4x - 1)
= (4x - 1)²
The area of a square = s² ( where s is the length of the side )
s² = (4x - 1)², thus
s = 4x - 1 ← length of side of square

Tamara bought a sweater that was 30 percent off the original price.the original price of the sweater was $80.How much did Tamara pay
Answer:
24
Step-by-step explanation:
Multiply the Price Percentage by the Original Price
Multiply the original price and the percentage that represents the sale price; the result is the sale price of the blazer in dollars: $90 × 0.7 = $63. So if the blazer is on sale for 30 percent off, you'll pay the remaining 70 percent of the price, which is $63.

Yes; They should charge $1.20 for and apple and $1.00 for an orange.
C = 0.5n + 5
C=cost (£)
n=number of miles travelled
Calculate the cost of a journey that is 25 miles.
Show your working out and write the answer in the box below.
Answer:
cost of journey of 25 miles = £ 17.5
Step-by-step explanation:
Base on the equation the cost of the journey can be represented as
C = 0.5n + 5
where
C = cost in £
n = number miles covered
To calculate the cost of a journey that is 25 miles we have to insert the value of n as 25 in the equation. Therefore,
C = 0.5n + 5
n = 25
C = 0.5(25) + 5
C = 12.5 + 5
C = £ 17.5
cost of journey of 25 miles = £ 17.5

Use calculations and words to show
this quadrilateral meets the
definition of a kite.
Answer:
1) The correct options are;
Two pairs of consecutive sides (but not all four sides) are congruentThe diagonals are perpendicular2) Yes, the quadrilateral meets the condition for the definition of a kite
Step-by-step explanation:
1) A kite has two pairs of adjacent equal sides, therefore a kite consists of two isosceles triangles adjacent to each other sharing the same base
Which shows that the diagonals which consists of the base of the two isosceles triangles and the bisector of the angles on the opposite sides of the common base of the isosceles triangles are perpendicular to each other
Therefore, the correct options are;
Two pairs of consecutive sides (but not all four sides) are congruentThe diagonals are perpendicular2) The coordinates of the given quadrilateral are;
D = (-3, 4), A = (3, 6), B = (5, 0), C = (-2, -4)
Therefore, the length of DA = √((-3 - 3)² + (4 - 6)²) = 2·√10
the length of AB = √((5 - 3)² + (0 - 6)²) = 2·√10
The length of DC = √((-3 - (-2))² + (4 - (-4))²) = √(65)
The length of CB = √((-2 - 5)² + (-4 - 0)²) = √(65)
Therefore, the figure has two pairs of congruent consecutive sides but not all four sides
The slope of the bisector CA = (6 -(-4))/(3 - (-2)) = 2
The slope of the bisector DB = (0 - 4)/(5 - (-3)) = -0.5 = -1/2
Therefore, the diagonals are perpendicular which shows that the quadrilateral meets the condition for the definition of a kite.

Mark brianliest if my answer suit your question.
The percentage of fruits that are apple are 25%.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Total fruits= 20
Number of apples= 5
let the percent of fruits that are apple be x.
So, x% of 20= 5
x/100 (20) = 5
x/5 = 5
x = 25%
Hence, the percentage is 25%.
