the number of variable in the separation 2×+3y+5 is ____​

When m = -4, the expression 8100.3m evaluates to -24300.12.

To evaluate the expression 8100.3m for m = -4, we substitute the value of m into the expression:

8100.3m = 8100.3(-4)

Now, we can calculate the value:

8100.3(-4) = -24300.12

Therefore, when m = -4, the expression 8100.3m evaluates to -24300.12.

Answer:

62

Step-by-step explanation:

t=digit in the tens place

u=digit in the units place

t=3*u

original number=t*10+u

number with reversed digits=u*10+t

u*10+t=t*10+u-36

u*10+(3*u)=(3*u)*10+u-36

10u+3u-30u-u=-36

-18u=-36

u=2

t=3*u=6

Original number = 62

The side length of the leg of the special right triangle is equal to 7√2 / 2 units.

In this problem we find the case of special right triangle known as 45° - 90° - 45° triangle, where internal angles are 45°, 90° and 45° and whose side relationship is shown below:

r = √2 · x = √2 · y

Where:

If we know that r = 7, then the side length of the leg is:

x = y = √2 · r / 2

x = y = √2 · 7 / 2

x = y = 7√2 / 2

To determine whether the furnace will be adequate for a 1,400 square foot house with a 9-foot ceiling, we need to calculate the volume of the house and compare it to the volume the furnace is designed to heat.

The volume of the house can be found by multiplying the square footage by the ceiling height:

1,400 sq ft x 9 ft = 12,600 cubic feet

Since the furnace is designed to heat 10,000 cubic feet, and the house has a volume of 12,600 cubic feet, the furnace may not be adequate for heating the house. The furnace is not capable to heat the entire house.

Answer:

  36.644 mL . . . . depending on your value of π (see below)

Step-by-step explanation:

The height of Micah's cup is found from the radius and slant height. The radius is half the diameter, so is 36 mm. Then the height h is ...

  45² = 36² +h²

  h = √(45² -36²) = 27 . . . . . mm

The volume is given by the formula ...

  V = (1/3)πr²h

  V = (1/3)π(36 mm)²(27 mm) = 11664π mm³

For π = 3.14

  11664(3.14) mm³ ≈ 36,625 mm³ = 36.625 mL

For π = 3.14159265

  11665π mm³ = 36,644 mm³ = 36.644 mL

Step-by-step explanation:

Given statement solution is :- The present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

To calculate the present value of an investment with compound interest, we can use the formula for the present value of an annuity:

PV = A *\((1 - (1 + r)^(-n)) / r\)

Where:

PV = Present value

A = Annual payment or cash flow

r = Interest rate per period

n = Number of periods

In this case, the annual payment (A) is R13,000, the interest rate (r) is 10% per year, and the investment is made for 8 years (n).

Using the formula and substituting the given values, we can calculate the present value:

PV = \(13000 * (1 - (1 + 0.10)^(-8)) / 0.10\)

Calculating this expression:

PV = \(13000 * (1 - 1.10^(-8)) / 0.10\)

= 13000 * (1 - 0.46318) / 0.10

= 13000 * 0.53682 / 0.10

= 6977.66 / 0.10

= 69776.6

Therefore, the present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

Answer:

C

Step-by-step explanation:

For these types of problems, its important that we focus on the base as well as the lengths of the base and any other given lengths.

Here, the net has a base that forms a square with side lengths of 8mm.

So automatically, we can eliminate choices a and d as both have a base that is a triangle rather than a square.

We've also noticed that the base has a length of 8mm

If we look at B and C closely, we can tell that B has base lengths of 10mm while C has base lengths of 8mm.

So C is the correct answer choice.

a.

b. The average acceleration of the car between 6.0 and 8.0 seconds is 15.0 m/s²

Average acceleration is the rate of change of velocity with time.

From the graph, we know that the gradient of each section is the acceleration of the car in each section.

For each section, we have the condition

The average acceleration a = (v₂ - v₁)/(t₂ - t₁) where

So, substituting the values of the variables into the equation, we have

a = (v₂ - v₁)/(t₂ - t₁)

a = (45.0 m/s - 15.0 m/s)/(8.0 s - 6.0 s)

a = (30.0 m/s)/(2.0 s)

a = 15.0 m/s²

When locating points or other geometric objects precisely on a continuum, such as Euclidean space, a coordinate system is a technique that uses one maybe more integers or coordinates. Locating a point or item on an a double plane requires the use of coordinates, which are pairs of integers. Two numbers called the y and x coordinates are used to describe a point's location on a 2D plane. a collection of integers that represent specific locations.

4, 8/2, 12/3 are equal to 4, when simplified, which means they are equivalent in nature.

A fraction is defined as numerical representation for part of a whole which represents a rational number.

If the denominator is 1, the numerator can be taken as 4, so the fraction would become \(\frac{4}{1}\) = 4

If the denominator is 2, the numerator can be taken as 8, so the fraction would become \(\frac{8}{2}\) = 4

Answer:

30 ants are in the ant farm.

---------------------------------------

If there are 40 ants on the second part of the scale,

multiply 5 by 8 to get 40 because there are 5 ants for each row, and 8 rows total

and there are 10 ants visible on the first side of the scale, the second part of the scale would have the majority and there would be a big inbalance. To fix that, we could say there are 30 ants in the ant farm, because there are 10 ants on the scale. \(10 + 30 = 40\), so that would make the scale balanced.
