Answer:
D 70
Step-by-step explanation:
Hello there!
A triangle formed inside of a circle using the diameter ( segment RQ ) is a right triangle
Meaning that the angle across from the hypotenuse ( diameter ) is a right angle ( = 90 degrees )
That being said we are given two angles (90 and 20 ) so we can easily calculate the measure of the missing angle
Remember the sum of the angles in a triangle is equal to 180 so we can find the missing angles by subtracting the given angles ( 90 and 20 in this case ) from 180
angle PRS = 180 - 90 - 20
180 - 90 = 90
90 - 20 = 70
Therefore your answer is D. 70
The graph of x+y= -9 is shown. Use the Add Arrow
tool to graph the equation y = 2x + 3 on the same
coordinate plane. Use the Add Point tool to plot the
solution to this system of linear equations.
Answer:
Step-by-step explanation:
y = -x - 9
y = 2x + 3
Find point of intersection
2x + 3 = -x - 9
x = -4
Intersection: (-4,-5)

Answer:
x = (9/2)√2 = 4.5√2
Step-by-step explanation:
We know the hypotenuse of an isosceles right triangle is √2 times the length of the side:
9 = x·√2
9√2 = 2x . . . . multiply by √2
(9/2)√2 = x . . . divide by 2

Answer:
6% growth
Step-by-step explanation:
The equation =
A = 2300(1.06)⁷
What does 0.06 represent in the equation?
The formula for Exponential growth =
y = a (1 +r)^t
Where
y = Size after time t
a = Initial size
r = Growth rate in Percentage
t = Time t
Equating both Equations together
y = a (1 +r)^t = A = 2300(1.06)⁷
1 + r = 1.06
r = 1.06 - 1
r = 0.06
Converting to percent
r = 0.06 × 100
r = 6% growth rate

Pete runs an ice cream stand that also sells snow cones served in paper cones. The paper cones he usually uses have a radius of 3 inches and a height of 4 inches, but his supplier is out of them. As a replacement, he purchases paper cones with a radius of 4 inches and a height of 3 inches. How do the volumes of the original and replacement cones compare? A. The replacement cone holds 3π cubic inches more than the original. B. The original and replacement cones have the same volume. C. The replacement cone holds π cubic inches more than the original. B. The original cone holds π cubic inches more than the replacement.
Answer:
The correct answer is;
The replacement cone holds 4·π cubic inches more than the volume of the original cone
Step-by-step explanation:
The given measurements of the cones are;
The radius of the original cone, r₁ = 3 inches
The height of the original cone, h₁ = 4 inches
The radius of the replacement cone, r₂ = 4 inches
The height of the replacement cone, h₂ = 3 inches
The volume of a cone, V = (1/3)·π·r²·h
The volume of the original cone, V₁ = (1/3)·π·r₁²·h₁
∴ V₁ = (1/3) × π × (3 in.)² × 4 in. ≈ 37.7 in.³
The volume of the replacement cone, V₂ = (1/3)·π·r₂²·h₂
∴ V₂ = (1/3) × π × (4 in.)² × 3 in. ≈ 50.27 in.³
The ratio of the volume of the two cones is given as follows;
Volume ratio = V₁/V₂
∴ Volume ratio = (1/3) × π × (3 in.)² × 4 in. /((1/3) × π × (4 in.)² × 3 in.) = 3/4
The difference in volume, ΔV = V₂ - V₁ = (1/3) × π × ((4 in.)² × 3 in. - (3 in.)² × 4 in. = 4·π in.³
Therefore, the volume of the replacement cone is 4·π in.³ more than the volume of the original cone.

James earns 20 allowance every month and 30 for each a on his report card
PART A- Identify the independent and dependent variables
PART B- Write a function that describes the situation
f(x)
Answer:
Part A - the independant variable is the monthly allowance, and the dependent amount is the one that he has to get As for in order to receive it.
Part B - y = 30x + 20
Step-by-step explanation:
Part A; The independent variable is monthly allowance and the dependent variables is earns in report card.
Part B; The function for this situation is;
⇒ f (x) = 30x + 20
Where, x is number of report card.
What is mean by Function?
A relation between a set of inputs having one output each is called a function.
Given that;
James earns 20 allowance every month.
And, Earn 30 for each a on his report card.
Now,
Let number of report card = x
Then, We can formulate the equation as;
⇒ f (x) = 30x + 20
Where, x is number of report card.
Hence, The independent variable is monthly allowance and the dependent variables is earns in report card.
Thus,
Part A; The independent variable is monthly allowance and the dependent variables is earns in report card.
Part B; The function for this situation is;
⇒ f (x) = 30x + 20
Where, x is number of report card.

Will give brainliest. Pls help. The volume of a cylinder is 300 feet^3. Find the volume of a cone and a sphere that have the same height and radius as the cylinder.
Cone:
Sphere:
Answer:
Cone: 100ft^3
Sphere: 200ft^2
Step-by-step explanation:
Firstly, the volume of a cone is 1/3 of the volume of the cylinder. It's literally in the formula:
[tex]V_{cone} = \frac{h \pi r^2}{3}\\\textrm{As you can notice, }\pi r^2\textrm{ is the area of the base, like in the cylinder formula}\\[/tex]
So we can just instantly tell that the volume of the cone is 100feet^3.
Not for the sphere - we can assume that if the height is the same, it's equal to two radiuses, or simply - to the diameter. Let's use the formula for the volume of a sphere, but substitute one of the radiuses with [tex]\frac{h}{2}[/tex]
[tex]V_{sphere} = \frac{4\pi r^3}{3} = \frac{2\pi r^2 h}{3} = \frac{2h\pi r^2}{3} = 2\cdot V_{cone}[/tex]
So we can instantly tell that the volume of the sphere is 200feet^3

Determine if the graph of the function opens up or down. Explain how you know
Answer:
Opens up
Step-by-step explanation:
x^2+2x-15
Standard form: ax^2+bx+c
If a<0, then the graph opens down
If a>0, then the graph opens up.
In this case: 1x^2+2x-15
a=1
Since 1>0 then the graph opens up.
