A cupcake recipe calls for 1/4 tablespoons of salt and 1/8 tablespoons of vanilla. How many tablespoons of salt and vanilla are required?
Answer:
3/8 tablespoons
Step-by-step explanation:
When we add fractions, we have to make each fraction a common denominator.
So we get 1/4 into 2/8 and we have 1/8
So we add and get 3/8

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
a is a legb is another legc is the hypotenuse[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse
Step-by-step explanation:
Step 1: Define
Identify variables
a = 8
b = 12
c
Step 2: Solve for c
Substitute in variables [Pythagorean Theorem]: 8² + 12² = c²Evaluate exponents: 64 + 144 = c²Add: 208 = c²[Equality Property] Square root both sides: √208 = cRewrite: c = √208Simplify: c = 4√13Step 3: Define Pt. 2
Identify variables
Angle θ
Adjacent leg = 8
Hypotenuse = 4√13
Step 4: Find
Substitute in variables [Cosine]: [tex]\displaystyle cos\theta = \frac{8}{4\sqrt{13}}[/tex]Rationalize: [tex]\displaystyle cos\theta = \frac{2\sqrt{13}}{13}[/tex]Answer:
Solution given;
In right angled triangle with respect to θ
perpendicular: opposite side: [P]=12
base:adjacent:[b]=8
hypotenuse [h]=?
cosθ=?
According to the Pythagoras law
h²=p²+b²
h²=12²+8²
h=[tex] \sqrt{208}[/tex]
h=[tex] 4\sqrt{13}[/tex]
Now
we have
Cos θ=[tex]\frac{adjacent}{hypotenuse}[/tex]
Cos θ=[tex]\frac{8}{4\sqrt{13}}[/tex]
by rationalising it
Cos θ= [tex] \frac{2\sqrt{13}}{\sqrt{13}×\sqrt{13}}[/tex]
Cos θ= [tex] \frac{2\sqrt{13}}{13}[/tex]

Given csc A= 37/12 and that angle A is in Quadrant I, find the exact value of sec A in
simplest radical form using a rational denominator.
Answer:
Step-by-step explanation:
Below is the pic of how this would be set up in order to determine what it is you are looking for. The angle is set in QI, and since csc A is the reciprocal of sin, the ratio is hypotenuse over side opposite. Solve for the missing side using Pythagorean's Theorem:
[tex]37^2=12^2+b^2[/tex] and
1369 = 144 + b² and
1225 = b² so
b = 35
The sec ratio is the reciprocal of cos, so if cos is adjacent over hypotenuse, the sec is hypotenuse over adjacent, which is 37/35
What are the coordinates of the point that is 1/5 of the way from A(-7,-4) to
B(3, 6)?
A. (-5,0)
B. (0,3)
C. (-5,-2)
D. (1,4)
Answer:
C. (-5, -2)
Step-by-step explanation:
I used
x1 + / (x2 - x1), y1 + / (y2 - y1)
so
-7 + 1/5(3 - (-7)
-7 + 1/5 (10)
-7 + 10/5
-7 + 2 = -5 (X)
then
-4 + 1/5(6 - (-4)
-4 + 1/5(10)
-4 + 10/5
-4 + 2 = -2 (Y)

The Pike Ferris Wheel in downtown Long Beach is 90 feet tall.
Select all of the expressions below that could be used to find the distance, measured in
feet, that one of the gondolas will travel in one revolution of the giant wheel.
Answer:
[tex]C = 45 * 2\pi[/tex]
[tex]C = 90\pi[/tex]
Step-by-step explanation:
Given
[tex]h = 90[/tex] -- height of the wheel
Required
The expression for the distance traveled in 1 revolution
The height of the wheel implies that:
[tex]d =90[/tex] --- diameter equals height
The distance in 1 revolution is calculated by calculating the circumference of the wheel using:
[tex]C = 2\pi r[/tex] or [tex]C = \pi d[/tex]
Where
[tex]r = \frac{1}{2} * d[/tex]
[tex]r = \frac{1}{2} * 90[/tex]
[tex]r = 45[/tex]
So, we have:
[tex]C = 2\pi r[/tex]
[tex]C = 2\pi * 45[/tex]
[tex]C = 45 * 2\pi[/tex]
[tex]C = \pi d[/tex]
[tex]C = \pi * 90[/tex]
[tex]C = 90\pi[/tex]
Which graph below shows a line that contains ordered pairs that are solutions of the equation shown?
y = –x + 4
Given:
The equation is:
[tex]y=-x+4[/tex]
To find:
The graph of the line that contains ordered pairs that are solutions of the given equation.
Solution:
We need to find the graph of the given equation.
We have,
[tex]y=-x+4[/tex]
At [tex]x=0[/tex], we get
[tex]y=-0+4[/tex]
[tex]y=4[/tex]
So, the x-intercept of the given equation is at point (0,4).
At [tex]y=0[/tex], we get
[tex]0=-x+4[/tex]
[tex]x=4[/tex]
So, the y-intercept of the given equation is at point (4,0).
From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).
Therefore, the correct option is C.
The volume of a cylinder is 1044 cm^3. The radius of the base of the cylinder is 6cm. What is the height of the cylinder?
Answer:
9.24
Step-by-step explanation:
Formula Cylinder = πr² * h
Let's work backwards
Use 3.14 for π
3.14 * (6)² * h = 1044
3.14 * 36 * h = 1044
113.04 * h = 1044
h = 1044 ÷ 113.04
h ≈ 9.24

The number line inequality will be true for the following condition given in this problem:
When a = 0 and c = -8.
How are real numbers represented on a number line?On a number line, real numbers increase from left to right, meaning that:
Large negative numbers come before small negative numbers, which come before small positive numbers, and finally, come the large positive numbers.
For this problem, the inequality is:
c > b > a.
Which means that:
c is to the left of b.b is to the left of a.We have that b < -1, hence:
c < -1 (can be -2, -3, -4, and so on...).a > -1 (can be 0, 1, 2, 3, and so on)...Then the conditions that make the statement b < -1 true are given as follows:
When a = 0 and c = -8.

15.56 in.
Step-by-step explanation:
i'm pretty sure i did it right, but im not sure. i haven't done geometry in like over 2 years.
find the hypotenuse of the triangle with 7 in. and 12 in. as your legs with the Pythgorean theorem (a^2 + b^2 = c^2, c equals the hypotenuse)
use that number you just got (I got ) and use it as one leg, and 7 in. as the other leg, with d as your hypotenuse
use the Phythagorean theorem again to find d, andddd... you've got your answer!
Answer: Ok well when you do the math you get 14.76 then round to the nearest tenth of an inch you get 17.8. So, d ≈ 14.8

Step-by-step explanation:
Hayden wants to find out what grade he must receive on his next math test in order to receive a 90 on his report card. His current math test grades are a 90, 89, 91, and 92. Which measure of center would be best for him to use
Answer: Mean
Step-by-step explanation:
Mean is best used when the numbers in the data set are close together and the number of outliers are limited because outliers will either increase or decrease the mean such that it would not be a true representation of the data set.
In cases like the above however where the numbers are generally in the same range, the mean would provide a center measure that is the most representative because it would simply be a simple average of the numbers.

Tobias is constructing barriers to prevent cars from driving on a bike path. He can make conical pylons using the dimensions shown. If he used the
same amount concrete to construct a spherical barrier, how tall would it be? Use 3.14 for and round your answer to the nearest tenth of a foot. PLS HELPPP !
Answer:
1.6 ft.
Step-by-step explanation:
Given that the conical pylons had a radius (r) of 1 foot and a height (h) of 2 foot. The volume of the conical pylons is:
Volume = πr²h/3
Therefore substituting gives:
Volume = π(1)²(2)/3 = 2π/3 ft³
Since the same amount of concrete is used to construct a spherical barrier, hence the volume of the sphere would be the same as the volume of the conical pylon.
Volume of sphere = 4πr³/3
4πr³/3 = 2π/3
2r³ = 1
r³ = 1/2 = 0.5
r = ∛0.5 = 0.8 ft.
Therefore the radius of the spherical barrier would be 0.8 ft. and the height would be 2r = 2(0.8) = 1.6 ft.

A spherical dodge ball has a radius r and a tennis ball has a radius 0.3r? What is the difference in volume between a dodge ball and a tennis ball?
Answer:
4/3π(0.973r³)
Step-by-step explanation:
Volume of a sphere = 4/3πr³
Given the radius of dodge ball rd = r
radius of tennis ball rt = 0.3r
Taking their difference
Volume difference = 4/3πrd³ - 4/3πrt³
Volume difference = 4/3π(r)³ - 4/3π(0.3r)³
Volume difference = 4/3π(r³ - 0.027r³)
Volume difference = 4/3π(0.973r³)
Hence the differmce in volume is 4/3π(0.973r³)
