Answer:

20 ft² - 4ft² = 16 ft²

Step-by-step explanation:

First we solve for the whole rectangle:

Formula:  A = ab

side length a = 5 in

side length b = 4 in

diagonal p = q = 6.4031242374328 in

perimeter P = 18 in

area A = 20 in²

Second we deduct the Area of the cutout of the Square

side length a = 2 ft

Area = a² = 4 ft²

Answer:

5 units were bought

Step-by-step explanation:

Firstly, let us calculate the total amount paid

If what was paid was $9.45, this cost includes the price of the coupon subtracted

Returning the coupon price, we have the total as;

9.45 + 0.5 = $9.95

So to get the number bought, we divide this total by the price for one

We have this as;

9.95/1.99 = 5

Answer:

5 units

Step-by-step explanation:

9.95/1.99 = 5

Answer:

your answer is x >18

Step-by-step explanation:

Jahsiah's mistake was he added 9 to both sides of the equation. He should have subtracted 9 from both sides of the equation.

Here's the solution

-2x+9<-27

-9 -9

-2x/-2x<-36/-2x

when u divide by negative in inequalities, u change the sign. So ur correct answer is x>18

Answer:

\(4 < x < 38\)

Step-by-step explanation:

\(21 - 17 = 4\)

\(21 + 17 = 38\)

The range of 3rd side is in between 4 to 38.

\(4 < side 3 < 38\)

A triangle has side lengths of 21 cm and 17 cm

side 1 = 21 cm

side 2 = 17 cm

What is the relation between side of triangle?

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Therefore,

length of side 3

\(21-17 < side 3 < 21+17\)

\(4 < side 3 < 38\)

Therefore the range of 3rd side is in between 4 to 38.

\(4 < side 3 < 38\)

\(x=-1\frac{2}{7}\)

\(y=-5\frac{3}{7}\)

Step-by-step explanation:

The method of elimination is a way of solving a system of equations. There are many steps involved in this process. First, one must manipulate one of the equations in the system by multiplying each term in it by a certain number such that one of the variables is the inverse of the other like the variable in the other equation. Then one must add the two equations. This will eliminate one of the variables in the equations. After doing so, one has to use inverse operations to solve for the other variable. Finally, one will back solve, substitute the value of the solved variable into one of the equations and solve for the remaining unknown variable.

\(\left \{ {{y=5x+1} \atop {y=-2x-8}} \right.\)

Manipulate the system;

\(\left \{ {{y=5x+1*(-1)} \atop {y=-2x-8}} \right.\)

Simplify,

\(\left \{ {{-y=-5x-1} \atop {y=-2x-8}} \right.\)

Add the equations,

\(\left \{ {{-y=-5x-1} \atop {y=-2x-8}} \right.\)

\(0=-7x-9\)

Inverse operations,

\(0=-7x-9\)

\(7x=-9\)

\(x=-\frac{9}{7}\)

\(x=-1\frac{2}{7}\)

Backsolve,

\(y=-2x-8\)

Substitute

\(y=-2(-\frac{9}{7})-8\)

Simplify,

\(y=-2(-\frac{9}{7})-8\)

\(y=\frac{18}{7}-8\)

\(y=\frac{18}{7}-8\\y=-\frac{38}{7}\)

\(y=-5\frac{3}{7}\)

Answer:

Sugar cookie dough packages cost 14 dollars each, and oatmeal cookie dough packages cost 16 dollars each.

Step-by-step explanation:

Let s equal the cost of a sugar cookie dough package, and o equal the cost of oatmeal cookie dough packages.

6s + 2o = 116

9s+12o = 318

therefore,

18s+6o = 348

18s+24o = 636

Subtracting them, we get -18o = -288, or 18o = 288

Therefore, o = 16, and 6s+32=116, so 6s=84, so s = 14

Step-by-step explanation:

Let the price per pound of coffee be c

Let the price ce per pound of butter be b.

We can form an equation based on the information given and this will be:

2c + b = 11.25 ....... i

3c + 2b = 18.50 ....... ii

From equation i, b = 11.25 - 2c ..... iii

Put the value of b into equation ii.

3c + 2b = 18.50

3c + 2(11.25 - 2c) = 18.50

3c + 22.50 - 4c = 18.50

-c = 18.50 - 22.50

c = 4.00

A pound of coffee cost $4.00

Since b = 11.25 - 2c .

b = 11.25 - 2(4.00)

b = 11.25 - 8.00

b = 3.25

A pound of butter costs $3.25

Caitlyn would need to know the population size of Montana in order to predict how many babies will be born this year in the state.

In order to predict how many babies will be born this year in Montana, Caitlyn needs to have access to the population size of Montana. The total fertility rate for Montana is 1.73, which is the average number of children a woman can expect to have throughout her lifetime. Knowing the population size of Montana will allow Caitlyn to have a better understanding of how many babies are likely to be born this year, as this number is directly correlated to the total fertility rate. By having access to both the population size and the total fertility rate, Caitlyn will be able to make a more informed prediction about the number of babies that will be born this year in Montana.

The total area of the composite figure is \(1242.5 mm^{2}\)

An area is defined as the total space occupied by flat (2-D) surface or shape of an object. It is measured in square units.

The total area of the composite figure is,

Let us split the composite figure into two figures.

Figure 1 as trapezium and figure 2 as triangle.

Area of trapezium(figure1), \(A_{1}= \frac{h}{2} (a+b)\)

a and b are the parallel sides and h is the distance between the parallel sides, a=20, b=30, h=38,

Then \(A_{1} =\frac{38}{2} (20+30)\)

⇒\(A_{1} = 19*50\)

⇒\(A_{1} = 950 mm^{2}\)

Area of triangle(figure2), \(A_{2}=\frac{1}{2}*b*h\)

Base, b=39mm h=15mm,

Then, \(A_{2} =\frac{1}{2} *39*15\)

⇒\(A_{2}= 292.5mm^{2}\)

\(A_{T} =A_{1} +A_{2}\)

⇒\(A_{T} = 950+292.5 = 1242.5 mm^{2}\)

Hence, the total area of the composite figure is \(1242.5 mm^{2}\).

5 km² = 5000000 m²

so, he has to pay 5000000p as tax.

The amount of tax the farmer must pay is 50000 Rupees.

A compulsory contribution the government has levied on people's income is called the tax , It is of various types and the money accumulated from that is used for the development of the nation.

It is given that the farmer has an area of 5 km²

The farmer must pay 1p tax for each m² of land he owns.

5km² = 5 * (1000)² m²

Area = 5 *10⁶ m²

The amount of tax the farmer needs to pay is

= 1* 5* 10⁶

= 5000000 p

100p = 1 rupees

This means that we will need to purchase a total of two bags of cookies and take out one cookie from one of the bags. This will give us a total of ten cookies. Therefore, we could purchase two different bags of cookies.

If there are three different kinds of cookies at the bakery (brownies, chocolate chip, and molasses), and you are going to purchase ten cookies for your advisory, then the total number of different bags of cookies you could purchase will be 36 different bags of cookies.

if we let the variable "n" equal the number of bags of cookies we will purchase, then we can use the following formula: 3n = 10. In this case, n would equal 3.33333333 (repeating), which is impossible because you cannot purchase a third of a bag of cookies. Therefore, we need to round that up to 4 bags of cookies.

Answer:

180°

Step-by-step explanation: We are given the co-ordinates of ΔDEF as D(-1,6), E(1,3) and F(6,3).

Now, after rotation the co-ordinates of the new triangle D'E'F' are D'(1,-6), E'(-1,-3) and F'(-6,-3).

As we see that, the co-ordinates of triangle DEF are multiplied by negative sign to obtain the co-ordinates of triangle D'E'F'.

This means that, the triangle DEF is rotated 180° to form triangle D'E'F' because rotating 180 changes (x,y) to (-x,-y).

So, the rotation applied is 180° to ΔDEF.

Answer:

Simplifying 19 + -4c = 17 Solving 19 + -4c = 17 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-19' to each side of the equation. 19 + -19 + -4c = 17 + -19 Combine like terms: 19 + -19 = 0 0 + -4c = 17 + -19 -4c = 17 + -19 Combine like terms: 17 + -19 = -2 -4c = -2 Divide each side by '-4'. c = 0.5 Simplifying c = 0.5
