Step-by-step explanation:
A can of juice is 6 inches high, and its base has a diameter of 4 inches. What is the volume of the can
Answer:
73.36
Step-by-step explanation:
A can of juice is 6 inches high
The diameter is 4
Radius= 4/2
= 2
Hence the volume of the can (cylinder,) can be calculated as follows
= πr^2h
= 3.142× 2^2 × 6
= 73.36 inches

Work out the percentage change when a price of £10 is increased to £14
Answer:
hmmm well.
Step-by-step explanation:
they added £4
Answer:
40%
Step-by-step explanation:
The formula for percentage change is given by:
[tex]\boxed{\text{Percentage change}=\frac{\text{New}-\text{Original}}{\text{Original}}\times100\% }[/tex]
In this case, the original price is £10 while the new price is £14.
Substitute the values into the formula:
Percentage change
[tex]=\frac{14-10}{10} \times 100\%[/tex]
= 40%

what is the slope of this graph?
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope = [tex]\frac{4-2}{1-3}[/tex]
= (-1)
Therefore, slope of the line is (-1).

For the polynomial, list each real zero and its multiplicity. Determine whether the graph
crosses or touches the x-axis at each x -intercept.
f(x) = 3(x + 7)(x + 3)^2?
A? B? C? D?
Answer:
B
Step-by-step explanation:
You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.
[tex]x+7=0\\x+3=0[/tex]
Solve them both and you get:
[tex]x=-7\\x=-3[/tex]
Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.
Therefore the answer is B since that agrees with everything we said.

A recipe for 20 rolls requires 5 tablespoons of butter. How many tablespoons of butter are
needed for 3 rolls?
answer : is 0.6 Tablespoon
step : 20 rolls = 5 tablespoon
5 rolls = 1 tablespoon
1tablespoon ÷ 5 rolls = 0.2 Tablespoon
0.2 x 3 Rolls = 0.6 Tablespoon
June uses 12 eggs to make cupcakes. She uses four eggs for each batch of cupcakes. Which expressions can be used to find the number of batches she makes?
Answer:
3 batches
Step-by-step explanation:
Given that :
Let Number of batches of cupcakes made = x
12 eggs was used to make x batches
Number of eggs used per batch = 4
If 4 eggs was used for a batch :
Number of batches of cupcakes made :
12 eggs / 4 eggs
= 3 batches

Answer:
57.6
Step-by-step explanation:
Parallel lines cut by transversals have proportional segments.
25/30 = 48/x
25x = 30 * 48
25x = 1440
x = 57.6
Solve for x
Solve for x
Solve for x
Solve for x
X=49°
Step-by-step explanation:
we have an isosceles triangle
thus our equation is
x+x+82=180°
=>2x+82°=180°
cancel 82 from both sides
=>2x=98
divide both sides by 2
therefore
X=49

You are standing on a footbridge that is 12 feet above a lake. You look down and see a duck in the water. The duck is 7 feet away from the footbridge. What is the angle of elevation from the duck to you? Round your answer to the nearest tenth. PLEASE HELPPPPPP
Answer:
Angle of elevation from the duck is [tex]59.7^{o}[/tex]
Step-by-step explanation:
This description can be represented by the three sides of a triangle and the given angle. Let the angle required be represented by θ. Thus applying the appropriate trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
So that,
Tan θ = [tex]\frac{12}{7}[/tex]
= 1.7143
θ = [tex]Tan^{-1}[/tex] 1.7143
= 59.7438
θ = [tex]59.7^{o}[/tex]
The angle of elevation from the duck is determined as [tex]59.7^{o}[/tex].

Answer:
Two lines will be parallel when their slopes are equal, and two lines will be perpendicular when their slopes are negative reciprocals of each other. Our slopes for these two equations are the coefficient for the x value. Both slopes are equal so these lines are parallel

B
What is the measure of ZACD?
A. 65
B.
40
C.
25
D.
50"
Answer:
C. 25°
Step-by-step explanation:
A useful relation for this geometry is "an exterior angle of a triangle is equal to the sum of the remote interior angles." The measure of arc BC is the same as the measure of central angle BDC, which is an exterior angle of triangle ACD.
__
Triangle ACD has sides AD and CD that are radii of the circle, so it is an isosceles triangle with angle A ≅ angle C. Exterior angle BDC is the sum of those congruent angles:
∠BDC = ∠CAD +∠ACD
50° = 2×∠ACD
25° = ∠ACD . . . . . . . . divide by 2
E. a distance of 5 multiply 10^5 cm in 2 multiply 10^-5 seconds
Answer:
The speed is 900,000,000 km/h
Step-by-step explanation:
The ratio of distance covered to time taken gives the speed of an object
[tex]Speed, \ v = \dfrac{Distance, \ d}{Time, \ t}[/tex]
Given that the distance covered, d = 5 × 10⁵ cm
The time to travel the given distance, t = 2 × 10⁻⁵ seconds
Therefore;
[tex]Speed, \ v = \dfrac{5 \times 10^{5} \ cm}{2 \times 10^{-5} \ s} = 2.5 \times 10 ^{10} \ cm/s[/tex]
In km/h, we have;
1 cm = 0.00001 km
∴ v = 2.5 × 10¹⁰ cm/s × 1 km/(100,000 cm) × 3,600 s/h = 900,000,000 km/h
The speed is 2.5 × 10¹⁰ cm/s or 900,000,000 km/h.
