We know that the volume of the prism is given by.

[tex]\text{Volume}=\text{(Base Area)}\times\text{height}[/tex]

[tex]\text{Base Area}=\dfrac{1}{2}\times(1.4+0.6)\times2[/tex]

[tex]\text{Base Area}=2\ \text{m}^2[/tex]

Now,

[tex]\text{Volume}=2\times1=2\ \text{m}^3[/tex]

Given that there is a twenty percent drop in the level of the pond during the first thirty minutes.

Because of this, the volume increases.

[tex]\text{Volume}=2\times0.8=1.6\ \text{m}^3[/tex]

Now, the rate of emptying the tank is,

According to the inscribed angle theorem the measure of angle Y is 43 degrees.

As the inscribed angle equals half of the central angle, the inscribed angle theorem is also known as the angle at the centre theorem. The centre angle is always the same since the endpoints are fixed, regardless of where it is on the same arc between the ends. The measure of the central angle is equal to double the measure of the inscribed angle occupied by the same arc, according to this theorem. OR. Half of a central angle that subtends the same arc is an inscribed angle. OR. The angle in a circle's centre is twice as large as any angle at its perimeter that the same arc occupies.

We know that, an inscribed angle is half of a central angle that subtends the same arc.

Here the given arc = 86 degrees.

The inscribed angle is half the arc of the circle thus,

angle Y = 1/2(86)

angle Y = 43 degrees.

A null hypothesis refers to a statistical hypothesis that assumes that there is no difference between two groups or variables. The null hypothesis may either be rejected or not rejected based on the statistical results obtained from a hypothesis test. A hypothesis test is a statistical test that is conducted to either accept or reject the null hypothesis based on the statistical results obtained.

When is the null hypothesis rejected?The null hypothesis is rejected when the p-value is less than or equal to a preconceived level of significance, α (usually set at 0.05 or 0.01).The null hypothesis is rejected when the calculated test statistic (such as t-test, z-test, or F-test) is greater than or equal to the critical value corresponding to the level of significance α.

When is the null hypothesis not rejected?The null hypothesis is not rejected when the p-value is greater than the preconceived level of significance, α. This means that there is not enough evidence to reject the null hypothesis.The null hypothesis is not rejected when the calculated test statistic is less than the critical value corresponding to the level of significance α.

The representation of 122 would depend on the base system being used. In a decimal (base-10) system, 122 would be represented as 122

The base system that would record this tally as 122 depends on the context in which the tally is being used.

If we assume that the tally is being used to represent a quantity or count, and we are using a base-10 (decimal) system, then 122 would be represented as 122 in decimal notation.

However, if the tally is being used in a different context or in a different base system, then the representation of 122 may be different. For example:

In a base-2 (binary) system, 122 would be represented as 1111010

In a base-8 (octal) system, 122 would be represented as 172

In a base-16 (hexadecimal) system, 122 would be represented as 7A

11.87 m² metal sheet would be needed to make the base area of tank.

Volume of cylinder, determines how much material it can carry, is determined by the cylinder's volume. A cylinder is a three-dimensional structure having two parallel, identical bases that are congruent.

It is given that capacity of a closed cylindrical vessel of height 2 m is 3080 liters

Let us assume that Radius of cylinder = r

Then Volume of cylinder = π ×r² ×h

= 2π ×r²× m³

1 m³ = 1000 liters

= 2000 π r²  liters

Volume of tank = Capacity

2000 π r² = 3080

=> 2000 × (22/7) × r² = 3080

=> r² = 49/100

=> r = 7/10 m

=> r = 0.7 m

Base Area of tank = TSA = 2πrh + 2πr²

= 2×(22/7)(0.7)×2 + 2×(22/7)×(0.7)²

= 3.0772 +8.792

The equation to show the relationship between x and y is y = 0.08x, where y is the amount of sales tax in dollars for the item and x is the cost of the item in dollars before tax.

Tax is a compulsory financial charge or some other type of levy imposed upon a taxpayer by a governmental organization in order to fund various public expenditures. A failure to pay, along with evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labour equivalent. Most countries have a tax system in place to pay for public, common or agreed national needs and government functions. Some levy a flat percentage rate of taxation on personal annual income, but most scale taxes based on annual income amounts.

This equation reflects the fact that the amount of sales tax for an item is 8% of its cost before tax.

Answer:

-3.375

Step-by-step explanation:

the point of a geometric sequence is that every new term is created by multiplying the previous term by a constant factor that is the same across the whole sequence.

that factor is called the common ratio.

so, 32 was multiplied by the common ratio, and we get -108 as result.

32 × cr = -108

cr = -108/32 = -27/8 = -3.375 = -3 3/8

By combinations, we get that there are 20,020 possible 6-topping pizzas.

Given that a pizza parlor offers a choice of 16 different toppings, we need to find the number of 6-topping pizzas that are possible. No double-orders of toppings are allowed. What is the number of 6-topping pizzas that are possible?

The formula for combinations is as follows:

ncr = (n!)/(r! * (n - r)!) where n = 16 (total number of toppings available)

r = 6 (number of toppings required for a pizza)

ncr = (16!)/(6! * (16 - 6)!)

⇒ ncr = (16!)/(6! * 10!)

⇒ ncr = (16 * 15 * 14 * 13 * 12 * 11)/(6 * 5 * 4 * 3 * 2 * 1)

⇒ ncr = (16 * 3 * 5 * 7 * 13 * 11)/(3 * 2 * 2)

⇒ ncr = 20,021

In this situation, the order of the toppings does not matter. Therefore, we cannot have a repeat of the same toppings, as mentioned. Hence the answer to the question is no. Thus, there are 20,020 possible 6-topping pizzas.
