in a triple batch of spice mix, there are 15 teaspoons of salt and 6 teaspoons of garlic powder. how much salt is used with 8 teaspoons of garlic powder?
Answers
Per batch amounts:
Salt = 15/3 = 5 teaspoons
garlic powder = 6/3 = 2 teaspoons
8 teaspoons of garlic powder number of batches:
8/2 = 4 batches
4 batches of salt
4 * 5 = 20 teaspoons
Answer:
2 teaspoons
Divide 15 by 5:
15/5 = 3
Divide 6 by 3:
6/3 = 2
Thus, there are 2 teaspoons of garlic powder used :)

Step-by-step explanation:
The missing measures can be found by making use of the properties of tangents, special triangles, trig functions, and circles.
RadiiAll of the incircle radii are the same length:
CJ = CK = CL = 4
AnglesAll of the segments to the incenter from the triangle vertices are angle bisectors. Of course, the sum of angles in a triangle is 180°, and the acute angles in a right triangle are complementary.
∠CML = ∠CMJ = 20°
∠CPL = ∠CPK = 40° . . . . . (∠P = 180° -40° -60° = 80°)
∠CNJ = ∠CNK = 30°
The central angles are complementary:
∠MCL = ∠MCJ = 70°
∠PCK = ∠PCL = 50°
∠NCJ = ∠NCK = 60°
TangentsThe two tangents from a vertex are congruent. Each will be the radius divided by the tangent of the (half) vertex angle.
ML = MJ = 4/tan(20°) = 11.0
PL = PK = 4/tan(40°) = 4.8
NJ = NK = 4/tan(30°) = 6.9
Angle bisectorsThe length from each vertex to the incenter will be the radius divided by the sine of the (half) vertex angle.
MC = 4/sin(20°) = 11.7
PC = 4/sin(40°) = 6.2
NC = 4/sin(30°) = 8.0
__
Additional comment
The given dimensions are slightly off. The angle at M is 19.9831°, or the length LM is 10.9899 units, or the radius is 4.00367. In order to keep the numbers nearly consistent, we have rounded to one decimal place. The 30° triangle is the only one with an angle that has a rational trig function (sine).
Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answers
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.
5 + 5Consider triangle ABC. Triangle A B C. Angle C is 80 degrees and angles B and A are y degrees. What is the value of y in the triangle? Angle y = °
Answers
Answer:
y=50°
Step-by-step explanation:
if all triangles add up to 180° you would subtract the angle you already know(80) from 180 which would be 100°
since there are 2 corners we dont know you would divide by 2 which would be 50°
I’ve asked 3 times and no one knows pls helpahh
Answers
Explanation:
The two angles shown combine to 180 degrees because the angles form a straight line.
(3x+18)+(4x+15) = 180
7x+33 = 180
7x = 180-33
7x = 147
x = 147/7
x = 21

Explain how you might go from gallons to cups using more than one conversion factor.
Answers
Answer:
use it as so-
4 cups/1 x 1 pint/2 cups= 2 pints
2 pints/1 x 1 quart/2 pints = 1 quart
1 quart/1 x 1 gallon/4 quarts= 1/4 gallons
therfore, 4 cups is equal to 1/4 gallons. hope this helps!
In order to convert gallons to cups using more than one conversion factor, first convert gallons to quarts and then convert quarts to cups.
How to convert gallons to cups?
The first step is to convert gallons to quarts:
1 gallon = 4 quarts
