top to the pool)
Part B: Based on the surface area you calculated, what is the total cost of the paint needed to paint
purchased?
Answer:
A. 320 sq. ft.
B. $1920

Find the complement and supplement of 73°:
Answer:
The complement of 73° is 17°
The supplement of 73° is 107°
Step-by-step explanation:
Two angles in a complementary are equal to 90°
∴ For complementary:
73° + x = 90°
x = 90°- 73°
∴ x = 17 °
Two angles in a supplementary are equal to 180°
∴ For supplementary:
73° + x = 180°
x = 180° - 73°
∴ x = 107°
a sample of a radioactive isotope had an inital mass of 130 mg in the year 2010 and decays exponentially over time. a measurmentin the year 2012 found that the samples masshad decayed to 80 mgwjat would be the expected mass of the sample in the year 2021 to the nearest whole number
The expected mass of the sample in the year of 2021 is given as follows:
9 mg.
How to define the exponential function?An exponential function is defined as follows:
y = a(b)^x.
For which the parameters are given as follows:
a is the initial value.b is the rate of change.The initial mass was of 130 mg, hence the parameter a is given as follows:
a = 130.
In two years, the mass decayed to 80 grams, hence the parameter b can be obtained as follows:
b² = 80/130
b = square root(80/130)
b = 0.78446454055.
This means that the exponential function for the mass of the sample in x years after 2010 is given as follows:
y = 130(0.78446454055)^x.
2021 is 11 years after 2010, hence the expected mass is obtained as follows:
y = 130(0.78446454055)^11
y = 9 mg.

By solving the expression (3x2 +4x − 15) ÷ (x +3) the quotient is 3x-5 and r=0
What do you meant by quotient?When solving a division problem, the quotient is obtained by dividing the dividend by the divisor.
Mathematically, we denote the outcome of this division by separating the quotient and remainder with a capital R. (see below). The entire number that results from simplifying a fraction is known as the quotient.
We can do it by long division method the required quotient is 3x-5 and r=0
not 3x-1 , r=1
multiply the divisor with 3x we will get 3x²+9x to cancel out the first term of dividend.
Now after solving we will get -5x -15
Now, multiply the divisor by -5 we will get -5x-15 which will cancel the entire dividend.
So that the quotient is 3x-5 and r=0

Step-by-step explanation:
Dashed lines have been added to the figure to help you see one way to cut it into manageable pieces.
Triangle BCD has a base BD of 10 units and a height CD of 6 units. Its area is ...
A = 1/2bh
A = 1/2(10)(6) = 30 . . . square units
Square BEFG has sides of length 6. Its area is ...
A = s²
A = 6² = 36 . . . square units
Trapezoid AGHI has bases of 14 and 16, and a height of 5. Its area is ...
A = 1/2(b1 +b2)h
A = 1/2(14+16)(5) = 75 . . . square units
The total area is the sum of the parts:
total area = triangle area + square area + trapezoid area

a+b=7
a-b=3
Answer: a=5 b=2
Step-by-step explanation:
They both satisfy the equation as 5+2=7 and 5-2=3
Hope this helps!
Here we have been given with two equations and we have to calculate the value of a and b by solving them simultaneously.
a + b = 7 (Equation No 1)a - b = 3 (Equation No 2)★ From Equation No 2 :
>> a - b = 3
>> a = 3 + b
★ In Equation No 1 :
Substituting here the value of a which we got above as (3 + b).
>> a + b = 7
>> 3 + b + b = 7
>> 3 + 2b = 7
>> 2b = 7 - 3
>> 2b = 4
>> b = 4 / 2
>> b = 2
★ Finding out value of a :
>> a = 3 + b
>> a = 3 + 2
>> a = 5 [tex] \: [/tex]

Papa Bear ate a quarter of the pie. Mama Bear ate a third of what was left. Baby Bear ate half of what was left. How much of the pie was left for Goldilocks
Mama bear only ate (1/4) of the pie, leaving Goldilocks with the remaining (1/8) fraction.
Which fraction is it?The fraction is expressed in the form a/b, where an is referred to as the numerator and b is referred to as the denominator. The fraction is a rational number that only divides two integers.
Let the pie's largest portion be a.
Half of the pie was consumed by Papa Bear.
Papa Bear then consumed = (1/2)a.
Rest of the pie is equal to a- (1/2).
a= (1/2)a
Mama bear consumed (half) of the remaining pie.
Mother bear consumed (1/2)(1/2).
pie portion a= (1/4) pie portion after mom bear has eaten = (1/2)
a- (1/4)a= (1/4)a
Baby bear afterwards consumed (half) of the remaining pie.
Baby bear ate (1/2)(1/4), thus. After the young bear has finished eating, the remaining pie is equal to (1/4) a- (1/8)a= (1/8)
The remainder of the component was given to GoldLiocks.
As a result, mom bear only ate (1/4) of the pie, leaving Goldilocks with the remaining (1/8) portion.
The complete question is Papa Bear ate 1/2 of a pie. Mama Benr ate 1/2 of what was left Baby Bear ate 1/2 of what
was left after Mama Bear finished.
3) What fractional part of the pie did Mama Bear eat?
4) What fractional part of the pie was left for Goldilocks?

A sequence has a rule to subtract 3/4 from the previous term. Create a sequence using this rule with at least 5 rational numbers.
1, 1/4, -1/2, -5/4, -2
Step-by-step explanation:
Let the first term of the sequence be a;
Since the sequence has a rule to subtract 3/4 from the previous term;
the second term will be a - 3/4
the third term will be (a - 3/4) - 3/4
=> a - 6/4
=> a - 3/2
the fourth term will be (a - 3/2) - 3/4
=> a - 9/4
the fifth term will be (a - 9/4) - 3/4
=> a - 12/4
=> a - 3
We can then create a hypothetical series by setting a = 1.
The first term => a = 1
The second term => a - 3/4 = 1 - 3/4 = 1/4
The third term => a - 3/2 = 1 - 3/2 = -1/2
The fourth term => a - 9/4 = 1 - 9/4 = -5/4
The fifth term => a - 3 = 1 - 3 = -2
The generated sequence is therefore:
1, 1/4, -1/2, -5/4, -2
Note: The numbers in the sequence are rational numbers since they all have a non-zero denominator.

Write a quadratic function in vertex form whose graph has the vertex (-2, - 13) and passes
through the point (-6,3).
Answer:
f(x) = ⁵/₈(x+2)² - 13Step-by-step explanation:
Vertex form of the equation of a quadratic function with vertex (h,k):
f(x) = a(x - h)² + k
To find a we need to put the point and the vertex into this equation:
3 = a(-6 + 2)² - 13
10 = a(-4)²
16a = 10
a = ⁵/₈
Therefore, vertex form of the quadratic function:
f(x) = ⁵/₈(x+2)² - 13

✓ ice cream have been stacked on top of the cone, after it was filled. The scoops are
completely round and have a diameter the same as the cone.
Find the volume of the two scoops of ice cream combined with the ice cream inside the
cone.
Answer:
(1/3) (44.5)π cm3.
Step-by-step explanation:
The volume of the two scoops of ice cream combined with the ice cream inside the cone can be calculated as follows:
Volume of cone = (1/3) π (3/2)2h = (1/3) π (4.5)8 = (1/3) (35.5)π
Volume of scoop = (1/6) π d3 = (1/6) (3)π
Total volume = (1/3) (35.5)π + 2(1/6) (3)π = (1/3) (44.5)π cm3.
