The number of cups of soda Sidney will use for 15 cups of ice cream is 45 cups of soda.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
From the table,
3.5 cups of ice cream = 10.5 cups of soda.
This means,
1 cup of ice cream = 3 cups of soda.
Multiply 15 on both sides.
15 cups of ice cream = 45 cups of soda.

Please help me out on my homework
Answer:
no solutions
Step-by-step explanation:
8(2w - 3) = 4(4w - 8)
Use distributive property.
16w - 24 = 16w - 32
subtract 16w from both sides.
-24 = -32
When the variable falls out of the equation as you are working on it, and you're left with a false statement, there is no solution.
Answer:
no solution
Step-by-step explanation:
to find the value of w, we have to isolate it on one side of the equation.
first, we distribute the numbers outside of the parentheses and multiply them to each term on the inside. this gives us:
16w - 24 = 16w - 32
next, we move 24 to the other side of the equation by adding 24 to both sides. by doing this, we get rid of 24 on the left side by making its value 0, and we add it to -32 on the right side. this gives us:
16w = 16w - 8
after this, we do the same with the 16w on the right side and subtract it from both sides. however, you might notice that there's a problem here.
when you try to move the 16w on the right side to the left side, you subtract 16w from itself, which gets rid of the variable entirely. whenever this happens, there are no values of the variable that make the equation possible- meaning that the answer is no solution.
hope this helped, good luck!

How many possible centers of rotation will produce an image of a left-pouting arrow?
The number of center of rotations to produce the image is (d) infinite
How to determine the number of centers?An arrow pointing to the left is symmetric around its central axis.
This means that any point along the central axis of the arrow can serve as a center of rotation to produce an image of a left-pointing arrow.
The central axis is a straight line that runs through the middle of the arrow from the tip to the base, and also extend through the arrow's depth.
Hence, the number of possible centers of rotation that will produce an image of a left-pointing arrow is infinite.

a piece in a wooden toy set is a sphere of radius 7cm , with a cylindrical hole of radius 1cm drilled through the center. find the volume of this piece. write the exact answer. do not round.
The volume of the piece is: 4489.33
To find the volume of this piece, we need to subtract the volume of the cylindrical hole from the volume of the sphere.
The volume of the sphere is given by the formula: V = (4/3) * pi * r^3
Where r is the radius of the sphere, so in this case: V = (4/3) * pi * (7cm)^3 = 1436 * 3.14 cm^3 = 4511.32 cm^3
The volume of the cylinder is given by the formula: V = pi * r^2 * h
Where r is the radius of the cylinder and h is the height of the cylinder, since the hole is drilled through the center of the sphere, the height of the cylinder is equal to the radius of the sphere, so: V = 3.14 * (1cm)^2 * 7cm = 21.99 cm^3
So the volume of the piece is: 4511.32 - 21.99 = 4489.33 cm^3

Express the following as a rate.
a) 20 litres of Petrol for R180
The rate of petrol in this case is R9 per liter.
What is rate?
In mathematics, rate is a measure of how one quantity changes in relation to another quantity. It is often expressed as a ratio or fraction, where the numerator represents the amount of change in the first quantity and the denominator represents the amount of change in the second quantity.
The rate of petrol can be expressed as the cost per liter. To find the cost per liter of petrol in this case, we can divide the total cost by the total amount of petrol:
Cost per liter = Total cost / Total amount
For the given scenario, we have 20 litres of petrol for R180. So the rate can be calculated as:
Rate = Total cost / Total amount = R180 / 20 litres
Simplifying the expression, we get:
Rate = R9 per litre

if jenna saves $2500 per year with an intrest of 10% compounded annually how much would she have in 30 years
Answer: Jenna would have $37,175 in 30 years if she saves $2500 per year with an interest rate of 10% compounded annually.
Step-by-step explanation:
To calculate the total amount Jenna would have after 30 years of saving $2500 per year with an interest rate of 10% compounded annually, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the final amount (principal + interest)
P = the initial principal (the amount Jenna saves each year, $2500 in this case)
r = the interest rate (10% in this case, so 0.10)
n = the number of times interest is compounded per year (annually in this case, so 1)
t = the number of years (30 in this case)
Plugging in the values:
A = $2500(1 + 0.10/1)^(1*30) = $2500(1.10)^30 = $2500(14.87) = $37,175
So, Jenna would have $37,175 in 30 years if she saves $2500 per year with an interest rate of 10% compounded annually.

The measure of angle m∠CBD is equal to 55°
How to to evaluate for the missing angle m∠CBDWe shall first find the measure of the angle m∠CDB so that we can evaluate for the measure of angle m∠CBD using the sum of interior angles of a triangle theorem as follows:
m∠ADB and m∠CDB are on a straight line and their sum is equal to 180° so;
m∠CBD + 80° = 180° {sum of angles on a straight line}
m∠CDB = 180° - 80° {subtract 80° from both sides}
m∠CDB = 100°
m∠BCD + m∠CDB + m∠CBD = 180° {sum of interior angles of a triangle}
25° + 100° + m∠CBD = 180°
125° + m∠CBD = 180°
m∠CBD = 180° - 125° {subtract 125° from both sides}
m∠CBD = 55°

Find the measure of angles 1 and 2.
Explain your reasoning as to how you determined the measurements of angles 1 and 2.
The required values of the angle ∠1 and ∠2 are 135°and 135°respectively.
Explain about angle.An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.
According to question:We need to find angle 1 and 2
So, by using corresponding angle theorem,
∠1 = 135°
Similarly for ∠2
By using vertically opposite angle,
∠2 =135°
Thus, required value of the angle are ∠1 = 135°, ∠2 =135°.
