Answer:

Width = 5 cm

Length = 7 cm

Step-by-step explanation:

Width = w

Length = 2w - 3

Perimeter = 24 cm

2* (length + width ) = 24

2*(2w-3 +w) = 24

2*(3w -3) = 24

3w - 3 = 24/2

3w - 3 = 12

3w = 12+ 3

3w = 15

w = 15/3

w = 5cm

Length = 2w - 3 = 2*5 - 3 = 10-3 = 7 cm

length = 7 cm

The solutions are £5575, £312.5 and £345 respectively.

Step-by-step explanation:

£1 = 11.15 kr

⇒ £500 = 500 × 11.15 = £5575

£1 = 1.25 CHF

⇒ £250 = 250 × 1.25 = £312.5

£1 = 1.18 euros

⇒ 407.10 euros = 407.10/1.18 = £345

Answer:

Option C, Carina should have subtracted 3.40 from 5.27.

Step-by-step explanation:

Step 1:  Convert words into an equation

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound.

3.40 + 0.85p = 5.27

Step 2:  Solve for p

3.40 + 0.85p - 3.40 = 5.27 - 3.40

0.85p / 0.85 = 1.87 / 0.85

p = 2.2

The error was found when she add 3.40 to 5.27 instead of subtracting.

Answer:  Option C, Carina should have subtracted 3.40 from 5.27.

Answer: Mean= 82.8

The solution to the system of equations is x = 4 and Y = 4.

To solve the system of linear equations, we can use substitution. Since we have the equation Y = 3/2x - 2, we can substitute this expression for Y in the first equation.

Substituting Y = 3/2x - 2 in 4x - 2y = 8:

4x - 2(3/2x - 2) = 8

Simplifying the expression:

4x - 3x + 4 = 8

x + 4 = 8

Solving for x:

x = 8 - 4

x = 4

Substituting the value of x into Y = 3/2x - 2:

Y = 3/2(4) - 2

Y = 6 - 2

Y = 4

Therefore, the solution to the system of equations is x = 4 and Y = 4.

The measure of each base angle is 56°.

Step-by-step explanation:

base angle + base angle + 68° = 180°

2x + 68° = 180°

2x = 112°

x = 112/2

x = 56°

Therefore, the measure of each base angle is 56°.

The required measure of each base angle is equal to 56°.

It involves understanding the properties of an isosceles triangle, which is the key to solving the problem. In an isosceles triangle, if two sides are equal, the angles opposite those sides are also equal.

Given that Kay is drawing a triangle with two equal sides of 8 cm and the angle between these sides measures 68°, the triangle is isosceles, and we know that the other two angles (the base angles) are equal due to this property.

The sum of all angles in any triangle equals 180°. Therefore, to find the measure of each base angle, we subtract the given angle from 180° and then divide by 2 (since the base angles are equal):

The sum of angles in a triangle = 180°.

The measure of the angle between the two sides = 68°.

The sum of the two base angles = 180° - 68° = 112°.

Measure of each base angle = 112° / 2 = 56°.

Therefore, the measure of each base angle in Kay's triangle is 56°.

1.4375

Step-by-step explanation:

Step 1:

Let the given equation be     [tex]1+12(4X-6)=-2[/tex]

To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.

Step 2:

Let us expand the equation as [tex]1+ (12*4X)-(12*6)=-2[/tex]

Step 3:

Let us expand it further as [tex]1+48X-72=-2[/tex]

Step 4:

To find X segregate X in one side and all other remaining terms in other side as follows

[tex]48X=-2+72-1[/tex]

After the simplification the numerical value is

[tex]48X=69[/tex]

Step 5:

Keep X along one side and bring 48 to the denominator of another side to find X as follows

[tex]X=69/48[/tex]

And the value of X is 1.4375

Answer:

x = 1 7/16

Step-by-step explanation:

1 + 1 2 ⋅ (4x − 6) = −2

Subtract 1 from each side

1-1 + 1 2 ⋅ (4x − 6) = −2-1

1 2 ⋅ (4x − 6) = −3

Distribute the 12

48x -72 = -3

Add 72 to each side

48x-72+72 = -3+72

48x =69

Divide by 48

48x/48 = 69/48

x =1 21/48

x = 1 7/16

difference of eleven and nine divided by two. What is the total value?

a. 9

b. 16

c. 5

d. 17

Source:

Previous question that can found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Side of the square = 4 units

Area of the square = 4 * 4 = 16 units

2. What is the total value?

Difference of eleven and nine divided by two = (11 - 9)/2

Difference of eleven and nine divided by two = 2/2 = 1

Area of a square whose side measures four units is added to the

difference of eleven and nine divided by two = 16 + 1

Area of a square whose side measures four units is added to the

difference of eleven and nine divided by two = 17

The correct answer is D. 17

The combined result of the area of a square with a side of four units and the arithmetic expression (11 minus 9) divided by 2 is 17.

Calculating the Combined Area and Arithmetic Expression

To solve the given problem, we need to calculate the area of a square with a side of four units and add this to the arithmetic expression (11 minus 9) divided by 2. First, let's find the area of the square. The area of a square is found using the formula area = side × side. Therefore, the area of our square is 4 units × 4 units = 16 square units.

Next, we calculate the arithmetic expression. The difference of eleven and nine is 11 - 9 = 2, and dividing this by two gives us 2 / 2 = 1.

Finally, we add the area of the square to this result: 16 square units + 1 = 17. The final answer is 17.

The theoretical probability of drawing an 'A' from the word 'ALABAMA' is 0.57. This result arrives from dividing the number of 'A's (4) by the total number of letters in 'ALABAMA' (7).

The question deals with a probability problem related to the selection of letters from the word 'ALABAMA'. The word 'ALABAMA' has 7 letters out of which 4 are 'A's. The theoretical probability is calculated as the number of successful outcomes divided by the total number of outcomes. Since we are interested in drawing an 'A', the successful outcomes are the number of 'A's which is 4, and the total outcomes are the total number of letters which is 7.

To calculate theoretical probability, you divide the number of successful outcomes by the total number of outcomes. In this case, the calculation will be 4 / 7 = 0.57 (rounded to the nearest hundredth).

So, the theoretical probability of drawing an A from the word 'ALABAMA' in decimal form, rounded to the nearest hundredth, is 0.57.

Step-by-step explanation:

Just divide 8.05 by 23

The answer you are looking for is 0.35.

To solve for any variable (N in this case) you must get it by itself, by doing the opposite operation. To do so for this problem, divide 23 from both sides. In doing so, N will be by itself, and you'd then just divide 23 from 8.05. Thus getting 0.35 as an answer.

Step-by-step explanation:

The given measurements are:

We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.

[tex] \therefore \: 39 + 21 = 60 > 16 \\ \\ \: \: \: \: \: \: 16 + 39 = 55 > 21 \\ \\ \: \: \: \: \: \: 16 + 21 = 37 \ngtr39 \\ \\ \because \: last \: mathematical\: statement \: is \:\\ defying \: the \: above \: law \\ [/tex]

Therefore, it is not possible to form a triangle with given measurements.

The given lengths cannot form the sides of a triangle because they dont satisfy the sides of a triangle rule.

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

Given here, are the sides 16 m, 21 m , 39m

now if the two sides are 16, 21 then their sum is 16+21 = 37 but 37<39 thus combination of lengths cannot form a triangle
