The allowable child and dependent care credit considering their pre-credit tax liability is $0
The following chart illustrates how their authorized child and dependent care credit was calculated:
If the revenue is less than $22,000, the full 22% would be permitted.
However, the eligible kid expense would only be allowed up to $7,000.
Consequently, the sum would be
= $7,000 × 22%
= $1,540
Since there is already a pre-credit tax liability, $0 should be taken into account because there would be no credit.
Due to their pre-credit tax liability, the available child and dependent care credit is therefore $0.

the midpoints of the sides of a triangle with area $a$ are joined to form a triangle with area $m$. what is the ratio of $m$ to $t$? express your answer as a common fraction.
While the midpoints of a sides of a rectangle having area $a$ are united to produce a triangle with size $m$, the area of a new triangle equals $frac14$ the area of a original triangle.
What does the word "area" mean?A "area" is the size or length of an a double surface, which is frequently measured in square units. It is employed to describe a shape's or object's size, such as the length, width, or height of a side, a bit of land, or even a geometrical figure. By dividing a form's length by its breadth, the area of the form may be calculated. For instance, a rectangle with dimensions of 5 units in length and 3 units in width has a surface area of 15 square units. The area of a circle is calculated using the formula r2, wherein r is the ring's radius. A fundamental geometric concept known as "area" has several applications in the sectors of construction, real estate, and horticulture.
How to fix?Assume that the original triangle has sides that are s1, s2, and s3. The triangle's area when the side's midpoints are united is [m=frac s 1s 2s 3 16]. This happens because the new triangle's area is $frac14$ the size of a original triangle since each side of a new triangle being half as long as the equivalent side of the old triangle.

According to the given condition, for 8181 values of n, q + r is divisible by 11.
What does division algorithm states?
The division algorithm for integers states that given any two integers a and b, with b > 0, we can find integers q and r such that 0 < r < b and
a = bq + r.
According to the given question:
q + r is divisible by 11 if and only if N is divisible by 11. This is because their difference is divisible by 11:
N − (q + r) = 100q + r − q − r = 99q = 11 x (9 x q) . So what you're asking is how many 5 -digit numbers are divisible by 11.
The first such number is 10010 = 910 x 11 because ⌈10000/11⌉=910 .
The last such number is 99990 = 9090 x 11 because ⌊100000/11⌋=9090 .
Therefore, in total there are 9090 – 910 + 1 = 8181 such numbers.

What is central angle theorem?.
The central angle theorem states the ratio of arc length and its radius.
What is a Central Angle?
The central angle is the angle that a circle's arc occupies in its centre. The arms of the central angle are formed by the radius vectors. In other words, it's an angle whose vertex is the centre of a circle and whose arms, which have the circle's two radii as their arms, cross at two separate positions. These two points make an arc when they are combined. The angle that this arc at the circle's centre subtends is known as the central angle.
According to the central angle theorem, we state that:

Remainder formula helps us to find the remainder when total number of possible sequence of games (i.e 3452) is divided by 1000.
The Remainder is 432.
We have given that
Number of players in team A = 7
Number of players in team B = 7
This problem is the same as the number of combinations problem. Let's assume team A is the winner (and we must remember to multiply our final result by 2 to account for the possibility that B is the winner).
A can win exactly 6 of the first k+6 games, and then Game k+7 (ending the series in exactly k+7 games), in (k+66) = (k+6k) ways, so we want
2∑k=06(k+6k).
This is 2⋅(1+7+28+84+210+462+924)= 3432.
Conversely, given a permissible series, allow the losing team to win all of the remaining (unplayed because superfluous) games, and you end up with a 7-7 tie.

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
where r is the radius of the base of the cone and h is the height of the cone.
When the conical cup is filled with water, there will be a difference in the radius of the water and the cup and a difference in the height of the water and the height of the cup (can be seen in the picture).
From the difference in radius and height of the water with the conical cup, a ratio can be made of similarity rule of triangle (see picture).
If the radius of water is [tex]r_{1}[/tex] and the height of water is [tex]h_{1}[/tex], radius of cup is [tex]r_{2}[/tex] and the height of cup is [tex]h_{2}[/tex], so:

The number of sweets that Dave have equals to 18 sweets.
What is the meaning of ratio?In mathematics, a ratio is a metric that shows how many times one number contains another. For instance, if we have 8 oranges and 6 lemons in a bowl of fruit, then, the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6:8 and the ratio of oranges to the total amount of fruit is 8:14.
Given data
Dave and martin ratio = 2:3
Dave is given 15 sweets.
The number of sweets that dave have now is computed as follows:
2/5 = 0.4= 40%
3/5 = 0.6 = 60%
Dave sweets will equals to:
= 15 sweets + (15 sweets * 1/5)
= 15 sweets + 3 sweets
= 18 sweets.

How do you solve a system of equations with X and Y?.
A system of linear equations is a collection of two or more linear equations that have two or more variables each. All of these equations are considered at once.
Finding a numerical value for each variable in the system that will simultaneously satisfy all of the system's equations is necessary to identify the one and only solution to a system of linear equations. There could be an unlimited number of solutions for some linear systems, whereas others might not have any. There must be at least as many equations as there are variables for a linear system to have a singular solution. However, this does not ensure an original answer. There is always one answer to a set of equations that makes sense. A consistent system, like the one we just examined, is said to be an independent system if it only has one solution. The two lines cross at one location in the plane and have different slopes. If the equations' slopes and y-intercepts match, the system is said to be consistent and considered a dependent system.
