Answer:
x=15, y=12, z=20
Step-by-step explanation:
y is the geometric mean of the two segments it divides.
9 · 16 = y^2
y=12
Use the pythagorean theorem to find x and z.
16^2 + 12^2 = z^2
z^2 = 400
z=20
9^2 + 12^2 = x^2
x^2 = 225
x=15

(Write an equation to go with the problem) Miranda goes to the store to buy 3 apples and some rice. The total was 6.50. If the rice cost $5.00, what was the cost per Apple?
Answers
Answer:
14.15 is the answer..comment it if that subtraction or multiple division
Answer: 3x + 5 = 6.50 is the equation where x represents the cost per apple and the cost per apple is 50 cents.
Step-by-step explanation:
In this situation we will represent the cost per apple by the variable x.
If she bought 3 apples, then 3 has to be multiply by x to find the cost so we will have the expression 3x
The rice cost $5 and she spend a total of 6.50 so 3x has to be add to 5 and it has to equal 6.50.
3x + 5 = 6.50 You can now solve for x in the equation to find the cost per apple
3x + 5 = 6.50
-5 -5
3x = 1.5
x= 0.5
This means the cost of an apple is 50 cents.

What is the perimeter of the rectangle?
Answers
The perimeter of the rectangle is 70cm.
What is perimeter?Perimeter is the total length of the sides of a two-dimensional shape.
What is the formula for the perimeter of square?Perimeter of the square is given by
P = 4a
where,
a is the side length of the square.
P is the perimeter of the square.
What is the formula for the perimeter for the rectangle?Perimeter of the rectangle is given by
P = 2( l + b)
Where,
l is the of the rectangle
b is the breadth of the the rectangle
According to the given question.
We have the perimeter of the square is 20cm.
⇒ 4a = 20
⇒ a = 5cm
⇒ Each side length of the square is 5cm
And a rectangle made of 10 squares.
⇒ length of the rectangle = 5×5 = 25cm
and the breadth of the rectangle = 2 × 5 = 10cm
Therefore, the perimeter of the rectangle = 2(25 + 10) = 2 × 35 = 70cm
Hence, the perimeter of the rectangle is 70cm.

Answers
Answer:
2223
Step-by-step explanation:
We need to find the value of 2021-2223+2425.
Firstly subtract 2223 from 2021.
2021-2223 = -202
Now add -202 and 2425. So,
2425 +(-202) = 2223
So, the value of 2021-2223+2425 is 2223. Hence, this is the required solution.

Answer:
y = -0.1
Step-by-step explanation:
1. subtract 1.3 from both sides 1.3 - y/0.2 - 1.3 = 1.8 - 1.3
2. simplify -y/0.2 = 0.5
3. multiply both sides by 0.2 0.2(-y/0.2) = 0.5 x 0.2
4. simplify -y = 0.1
5. divide both sides by -1 -y/-1 = 0.1/-1

Answer:

Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Cosine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:
[tex]a^2=b^2+c^2-2bc*cos(A)[/tex]
In triangle XYZ, we can find XZ using cosine rule:
[tex]XZ^2=XY^2+YZ^2-2(XY)(YZ)cosY\\\\subtituting:\\\\XZ^2=15^2+8^2-2(15)(8)cos(52)\\\\XZ^2=141.24\\\\XZ=11.88\\\\Using\ sine\ rule:\\\\\frac{XZ}{sin(Y)}=\frac{XY}{sin(Z)}\\\\\frac{11.88}{sin(52)}=\frac{15}{sin(Z)}\\\\sin(Z)=15*sin(52) /11.88\\\\sin(Z)=0.9946\\\\Z=sin^{-1}(0.9946)\\\\Z=85^0[/tex]
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
∠X + 52 + 85 = 180
∠X + 137 = 180
∠X = 43°
∠X = 3w - 35
3w - 35 = 43
3w = 78
w = 26
In triangle RST, using sine rule:
∠R = w + 17
∠R = 26 + 17
∠R = 43°
∠R + ∠S + ∠T = 180° (sum of angles in a triangle)
43 + 52 + ∠T = 180
∠T + 95 = 180
∠T = 85°

Write the equation of a line through (-1,-5) parallel to 3x-y=5, and in slope intercept form
Answers
Answer:
y = 3x -2
Step-by-step explanation:
The general equation form is;
y = mx + b
where m is the slope and b is the y-intercept
For the equation given;
y = 3x -5
the slope from here is 3
If two lines are parallel, they have equal slopes
This mean that the slope of the line we want to calculate too is 3
Now we can use the point slope format to get the correct equation
y-y1 = m(x-x1)
y+ 5. = 3(x+ 1)
y = 3x + 3 -5
y = 3x -2
