Answer:
∠AOB = 112°
Step-by-step explanation:
mentally draw line segment OC
that line bisects 124° so ∠OCB = 1/2(124°) = 62°
ΔOCB is isosceles because OB = OC
∠OBC = 62° because it is equal to ∠OCB
all triangle interior angles add up to 180°
∠BOC = 180° - 62° - 62° = 56°
∠AOC = 56° because OC was a bisector of ∠AOB
∠AOB = 56° + 56° = 112°

Which expression has a value of 13?
(20 ÷ 4) − 4 + 3 x 2
(18 ÷ 2) + 6 ÷ 6 + 3
(16 ÷ 4) + 3 x 4 − 1
(10 ÷ 2) − 3 + 4 x 2
Answers
The expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3
The PEMDAS rule
In order to calculate the expression, we need to use the PEMDAS rule which states:
P is parenthesisE is exponentM is multiplicationD is DivisionA AdditionS is subtractionFrom the question, we are to get the expression equal to 13.
From the given expression,(18 ÷ 2) + 6 ÷ 6 + 3 is equivalent to 13;
(18 ÷ 2) + 6 ÷ 6 + 3
9 + 6 ÷ 6 + 3
9 + 1 + 3
13
Hence the expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

Grace earned £27,000 last year.
She worked for 32.5 hours a week for 46 weeks.
Calculate her pay per hour.
Give your answer to 2 decimal places.
Answers
Answer:
£18.06
Step-by-step explanation:
The computation of her pay per hour is shown below:
= Total earnings last year ÷ Total number of hours she worked
= £27,000 ÷ (32.5 hours × 46 weeks)
= £27,000 ÷ 1,495 hours
= £18.06

Scale factor = 3
Step-by-step explanation:
Using similar triangles
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
Expand
3x+30 = 27x-90
3x-27x = -90 - 30
-24x = -120
x = 120/24
x = 5
For the larger triangle;
AC = 3x-10
AC = 3(5)-10
AC =15-10
AC = 5
AB = x+10
AB = 5+10
AB = 15
For the scale factor;
Since AT/AG = AB/AC
9/15 = 3/5
3*3/5*3 =3/5
Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3

The interior angle sum of a convex polygon is 2.520 How many sides does the polygon
have?
Answers
Complete Question
The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?
Answer:
16 sides
Step-by-step explanation:
The sum of angles in a polygon formula is given as:
(n - 2)180°
Where n = Number of sides of the polygon
Hence:
(n - 2)180°= 2520°
Divide both side by 180°
(n -2) = 2520/180
n - 2 = 14
n = 14 + 2 = 16
Therefore the number of sides the convex polygon has 16 sides.

[tex]\sqrt{125}[/tex]
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]
225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]
Answer:
x = 5[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² + 10² = 15²
x² + 100 = 225 ( subtract 100 from both sides )
x² = 125 ( take the square root of both sides )
x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form
