Answer:
The sector for 126 rubies would measure 126 degrees.
Step-by-step explanation:
First, a pie-chart is a circle, and there are 360 degrees in a circle. Because there are 320 total gemstones, 1 gemstone maps to 1.125 degrees. That is, 1.125 degrees per gemstone.
[tex]360\div320=1.125[/tex]
Knowing that, you can calculate the degrees in the pie-chart for any given number of gemstones. Just multiply the gemstones by 1.125.
[tex]112\times1.125=126[/tex]
The sector for 112 rubies would measure 126 degrees.
If you want to be extra sure, you can calculate that for all types of gemstones and add them up:
[tex]32\times1.125=36\\112\times1.125=126\\96\times1.125=108\\64\times1.125=72\\16\times1.125=18\\36+126+108+72+18=360[/tex]
That confirms they all add up to 360 degrees.

HELP what is the value of x?
Answers
Answer:
x = 16
Step-by-step explanation:
The triangle in question is an isosceles triangle which means :
m<Q = m<P and the sum of interior angles in a triangle is equal to 180
so we can find the value of x using the following equation:
5x - 2 + 3x + 3 + 3x + 3 = 180 add like terms
11x + 4 = 180 subtract 4 from both sides
11x = 176 divide both sides by 11
x = 16

cos theta = adjacent / hypotenuse
in this case it will be

we want h to be the subject so we will multiply both sides by 12

Answer:
x = 15
y = 9
Step-by-step explanation:
( 4y + 9 ) and 15y are co - interior angles.
Sum of co - interior angles is 180,
4y + 9 + 15y = 180
4y + 15y = 180 - 9
19y = 171
y = 171 / 19
y = 9
( 6x - 15 ) and ( 4x + 15 ) are alternate exterior angles.
Alternate exterior angles are equal,
6x - 15 = 4x + 15
6x - 4x = 15 + 15
2x = 30
x = 30 / 2
x = 15
Look at the image and answer the following question:
Answers
Step-by-step explanation:
Price = $1.70
V = 500ml → Litre
V = 500 ÷ 1000
V = 0,5 L
= $1.70 / 0,5L
= $1.70 × 2 / 0,5 × 2
= $3.40/L
Option → C
Answer:
$3.40
Step-by-step explanation:
As seen on image the price for 500ml is $1.70
1L = 1000ml so to find how much a Litre cost we need to multiply the given price by 2
1.70 x 2 = $3.40 is the answer to your question.

Find the value of 3x + 2 when 7 + x = 5
Answers
Answer:
5x I think I don't know is it right look in calculator
The value of (3x + 2) when (7 + x = 5) is -4.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have the following equation as -
x + 7 = 5
We can write -
x + 7 = 5
x = 5 - 7
x = - 2
Now, we have to find -
3x + 2
3(-2) + 2
- 6 + 2
- 4
Therefore, the value of (3x + 2) when (7 + x = 5) is -4.
