Answer:
x = 48 degrees
Step-by-step explanation:
This triangle is an isosceles which means that two of the angles are the same and all triangles add up to 180 degrees so we take the two angles we know and add them
66 + 66 = 132
Then we subtract that number from 180 to find the third angle
180 - 132 = 48
The translation from words to an algebraic expression, denoting the unknown by n is 0.15(n + 10,000)
<h3>Algebraic expression</h3><h3 />
let
unknown number = n
= n + 1000
- 15% of the amount by which a number exceeds 10,000
= 15%(n + 10000)
= 15/100(n + 10,000)
= 0.15(n + 10,000)

Answer:
B) 32
Step-by-step explanation:
8 x 4 = 32
<span>Last week he bought three apples for $3.90.
The cost of an apple = 3.9/3 = 1.3
This week he bought 2 more apples which totals 5 for $6.50
The cost of each apple = 6.5/5 = 1.3.
The cost of an apple in the two weeks is the same. Arnold bought more apples in the following week but there was a corresponding raise in price. When he bought fewer apples last week he never had to pay as much as he did the year later</span>
Answer:
Mass m = 20.04 grams
Correct question;
Sinker is a weight used by fishermen. A fisherman uses a sinker in the shape of a sphere with radius 0.75 cm. The sinker is made of lead, which has density 11.34g/cm^3. What is the mass of the sinker?
Step-by-step explanation:
Mass of an object can be defined as
Mass m = density p × Volume V
Given;
Density of the sinker = 11.34g/cm^3
Radius of the sinker = 0.75 cm
And we know that the volume of a sphere is given as;
V = 4/3 × πr^3
Substituting r, we have;
V = 4/3 × π × 0.75^3
V = 1.767 cm^3
Then we can calculate mass as;
m = pV
m = 11.34×1.767
m = 20.03778 g
m = 20.04 grams
