Answer:
Step-by-step explanation:
a + c = 321
6a + 4c = 1590
c = 321 - a
6a + 1284 - 4a = 1590
2a = 306
a = 153
c = 168

Work out the value of x.
Answer:
The value of x is 67.5
Step-by-step explanation:
The sum of the measures of the angles around a point is 360°
Let us solve the question
∵ In the given figure there are 3 adjacent angles around one vertex
→ By using the rule above
∴ The sum of their measures is 360°
∵ One of the angles is a right angle
∵ The measure of the right angle is 90°
∵ The measures of them are x, 3x, and 90°
∴ x + 3x + 90° = 360°
→ Solve the equation by adding the like terms to find x
∵ (x + 3x) + 90 = 360
∴ 4x + 90 = 360
→ Subtract 90 from both sides
∵ 4x + 90 - 90 = 360 - 90
∴ 4x = 270
→ Divide both sides by 4
∴ x = 67.5
∴ The value of x is 67.5

If a perfect square has a side length of x+2 and a perimeter of 44cm what is the value of x?
Answer:
The value of x is 9.
Step-by-step explanation:
Given that:
Side length of square = x+2
Perimeter of square = 44 cm
As all sides of a square are equal, therefore,
Perimeter of square = 4s
Putting all the values,
44 = 4(x+2)
44 = 4x+8
44-8 = 4x
36 = 4x
4x = 36
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{36}{4}\\x=9[/tex]
Hence,
The value of x is 9.

Answer:
x = 15
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 9 × 25 = 225 ( take the square root of both sides )
x = [tex]\sqrt{225}[/tex] = 15

2) Solve each problem with right angle at C:.
a) Find all sides and angles when B = 67º and c=16.
b) Find all sides and angles when b= 2 and c=6
Answer:
Step-by-step explanation:
a.)
<A = 90 - 67 = 23* A = (a^2 + 14.72^2 = 16^2) = a = 6.25
<B = 67* B = (sin67 = b/16) = sin67*16 = 14.73
<C = 90* C = 16
b.)
a = (a^2 + 2^2 = 6^2) = a = 5. 66 <A = (cosA = 2/6) = 70.53*
b = 2 <B = 90-70.53 = 19.47*
c = 6 <C = 90*
There are 4 colors of Starburst flavors: yellow, pink, red, and orange. If the probability of getting an orange is 2 5 2 5 , yellow is 1 10 1 10 , and the probability of getting red is 3 10 3 10 , what is the probability of getting pink?
Answer: 1/5
Step-by-step explanation:
From the question, we are informed that there are 4 colors of Starburst flavors: yellow, pink, red, and orange. We are further told that the probability of getting an orange is 2/5, yellow is 1/10 , and red is 3/10.
The probability of getting pink would be:
= 1 - [P(orange) + P(yellow) + P(red)]
= 1 - (2/5 + 1/10 + 3/10)
= 1 - (4/10 + 1/10 + 3/10)
= 1 - 8/10
= 2/10
= 1/5

Determine the coordinates of the midpoint of the line
segment with endpoints R(6,-2) and S(-3,-2).
O (1,2)
O (1.5, 2)
O (1.5, -2)
(3,-2)
Answer:
(1.5, -2)
Step-by-step explanation:
First subract -3 from 6 to find the total distance of the line segment.
6 - (-3)
Two negatives make a positive
6 + 3
9 units distance
Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.
-3 + 4.5
-3 + 3 + 1.5
(1.5, -2)
6 - 4.5
6 - 4 - 0.5
2 - 0.5
(1.5, -2)
The midpoint of segment RS is (1.5, -2).

Y=x. Given A(7,-4), B(6,4), and C(-1,-5), what are the coordinates of the vertices of A’B’C for the reflection
Answer:
The coordinates of the vertices of A'B'C' is:
A'(-4, 7)B'(4, 6)C'(-5, -1)Step-by-step explanation:
Given the coordinates of the triangle
A(7,-4)B(6,4)C(-1,-5)Reflection in the line y=x
We know that the rule of reflection in the line is y = x is:
(x, y) → (y, x)
Thus,
The coordinates of the vertices of A'B'C' for the reflection in the y = x
(x, y) → (y, x)
A(7, -4) → A'(-4, 7)
B(6, 4) → B'(4, 6)
C(-1, -5) → C'(-5, -1)
Thus, the coordinates of the vertices of A'B'C' is:
A'(-4, 7)B'(4, 6)C'(-5, -1)Divide 13 apples among 4 friends

A hot air balloons height varies directly as the balloons ascents the time in minutes. A hot air balloon rises at 350 feet in five minutes. Write a direct variation equation.
Answer:
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
Step-by-step explanation:
Given that :
Ballon height varies directly as the Ascent time in minutes
Height of hot air Ballon rises 350 feets in 5 seconds
Expressing as a direct variation :
Let height of Ballon = h
Time it takes to rise = t
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
