Tanisha and Bess are sisters. Tanisha is half as old as Bess. Bess is 6 years older than Tanisha.
How old is each sister?
A. Tanisha is 3, and Bess is 6.
B. Tanisha is 3, and Bess is 9.
c. Tanisha is 6, and Bess is 9.
D. Tanisha is 6, and Bess is 12.
Answer: a
Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3
The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.
We need to find the age of Tanisha and Bess.
What is an equation?A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Let the age of Tanisha be x.
Bess is 6 years older than Tanisha.
Now, Bess=x+6
Tanisha is half as old as Bess.
Now, Tanisha=1/2×Bess
⇒x=1/2×(x+6)
⇒x=6
So, Tanisha's age=6 years and Bess's age=12 years.

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker
By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.
What is the vοlume οf a cylinder ?The fοrmula tο calculate the vοlume οf a cylinder:
V = πr²h
where:
V = vοlume
r = radius
h = height
Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.
In this case, we have:
r = 9 mm
h = 32 mm
Sο the fοrmula becοmes:
V = π(9 mm)²(32 mm)
V = π(81 mm²)(32 mm)
V = 81π(32) mm³
V ≈ 8,159.15 mm³
Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.

Solve the two-step equation. 14=31.7-3x
Answer:
x=5.9
Step-by-step explanation:
First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

Find f(-5) if f(x) = 5x + 11.
A) 4
B) 5
C) 6
Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)
by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.
Now just simplify the right side to get -25 + 11 or -14.
So f(-5) = -14.

Step-by-step explanation:
The length of the y of the triangle is y = 96 inches
What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔXYZ
And , the measures of the sides of the triangle are
z = 75 inches
x = 26 inches
And , the measure of ∠Y = 135°
We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.
The Law of Cosines states that:
c² = a² + b² - 2ab cos(C)
where c is the side opposite angle C, and a and b are the other two sides.
In this case, we want to find the length of side y, which is opposite angle Y. So we can write:
y² = x² + z² - 2xz cos(Y)
Substituting in the given values, we get:
y² = 26² + 75² + 2(26)(75) cos(135°)
Simplifying, we get:
y² = 676 + 5625 - 2925√2
y² ≈ 9163
Taking the square root of both sides, we get:
y ≈ 95.76
Rounding to the nearest inch, we get:
y ≈ 96 inches
Hence , the length of y, to the nearest inch, is 96 inches

what does this mean 4x + 6y=9
12x + 18y=27
Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x /4 = −6y+9 /4
(Divide both sides by 4)
x= −3 /2 y+ 9 /4
Substitute
−3 /2 y+ 9 /4
for x in 12x+18y=27:
12x+18y=27
12( −3 /2 y+ 9 /4 )+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)
