We see that 24 is split into 8q.
Therefore 8q equals 24 --> 8q = 24 --> q = 24/8 = 3.
So q = 3.

Answer:
x = 46°
Step-by-step explanation:
the opposite angles of a cyclic quadrilateral are supplementary, sum to 180° , then
x + 134° = 180° ( subtract 134° from both sides )
x = 46°
Frank grows evergreen trees. He grew 535 trees for
the holiday season. In November he sold 215 trees
and in December he sold 275.
a. Write an expression. Then solve.
b. Frank replanted the left over trees with the
addition of 650 more trees. How many trees will
he have for next season?
Answer:
Frank grows 535 trees during holiday season in November sold 215 then dec sold 275535 minus 490 which gives a total of 45 trees left then to find out how many trees he will have next season 650 plus 45 gives 695The diagnols of a rhombus are 21 and 16 centimeters long find the area of the rhombus
Answer:
168 cm²
Step-by-step explanation:
The area of a quadrilateral with diagonals that intersect at right angles is half the product of the lengths of the diagonals. A rhombus is one such quadrilateral, so the area of this one is ...
A = 1/2(d1)(d2)
A = (1/2)(21 cm)(16 cm) = 168 cm²
The area of the rhombus is 168 cm².

Find the sixth term of the geometric sequence when a4=−8 and r=0.5
A. 4
B. 2
C. -4
D. -2
Answer:
D
Step-by-step explanation:
to find a term in the sequence multiply the previous term by r , then
a₄ = - 8 , so
a₅ = - 8 × 0.5 = - 4
a₆ = - 4 × 0.5 = - 2
The sixth term of the sequence will be negative 2. Then the correct option is D.
What is a geometric sequence?Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The fourth term (a₄) is negative 8 and the common ratio is 0.5.
Then the sixth term will be
For n = 5, we have
a₅ = a₁ · (r)⁵⁻¹
a₅ = a₁ · (r)⁴
a₅ = a₁ · r³ · r
a₅ = a₄ · r
a₅ = -8 · 0.5
a₅ = -4
Then the sixth term of the sequence will be
a₆ = a₁ · (r)⁶⁻¹
a₆ = a₁ · (r)⁵
a₆ = a₁ · r⁴ · r
a₆ = a₅ · r
a₆ = -4 · 0.5
a₆ = -2
The sixth term of the sequence will be negative 2.
Then the correct option is D.

We should find the leg of this right triangle, not the hypotenuse.
The hypotenuse, the longest side, is already given to us.

We know b and c, we need to find a.
[tex]\bf{a^2+9^2=15^2}[/tex] | square

Write an equation of a circle with the given center and radius center (3,4) and radius 6

B.) (x-3)^2 + (y-4)^2 = 6
C.) (x-3)^2 + (y-4)^2 =36
D.) (x+3)^2 + (y-4)^2 = 6
Answer:
a
Step-by-step explanation:
General equation of a circle : [tex](x-h)^2+(y-k)^2=r^2[/tex]
where (h,k) is at center and r = radius
Here, we want to find the equation of a circle with a given center at (3,4) and a given radius of 6
This is very simple, all we have to do is assign variables and then plug in the values of the variables into the general equation of a circle
First lets assign variables.
(h,k) is center and the circle has a given center at (3,4)
so (h,k) = (3,4) thus, h = 3 and k = 4
r = radius and the circle has a given radius of 6 so r = 6
now we plug this into the general equation of a circle.
recall equation : (x-h)² + (y-k)² = r²
h = 3, k = 4 and r = 6
plug in values
(x-3)² + (y-4)² = 6²
simplify exponent
(x-3)² + (y-4)² = 36
and we are done!
The answer is A

Find the area of the regular polygon with the given radius or apothem
Answer:
50 cm²
Step-by-step explanation:
Given that the regular polygon is a square, there are multiple ways you can jump directly to the answer. Perhaps the simplest is to use the formula for the area of a rhombus:
A = 1/2(d1)(d2)
where d1 and d2 are the lengths of the diagonals. Here, we see that half the diagonal is 5 cm, so the area is ...
A = (1/2)(10 cm)(10 cm) = 50 cm² . . . . area of the polygon
__
Alternate solution
If you want to use the radius and the number of sides in a formula, you can consider the area of each triangle formed by radii and a side. That triangle has area ...
A = 1/2r²sin(α)
where r is the radius and α is the central angle. For an n-sided polygon, the area is the sum of n of these triangles, and the central angle is 360°/n. Then the polygon area is ...
A = n/2·r²·sin(360°/n)
For n = 4 and r = 5 cm, the area is ...
A = (4/2)(5 cm)²(sin(360°/4)) = 2(5 cm)²(1) = 50 cm² . . . . area of square
_____
Additional comment
The formula is somewhat different if you start with the length of the apothem. One way to find the area is using the above formula and the relation between the radius and apothem:
r = a·sec(180°/n)
Another formula uses the apothem directly:
A = n·a²·tan(180°/n)
