Answer:

Step-by-step explanation:

65÷b+8×4=20

Put the value of b=5 in equation

65÷5+8×4=20

According to BDMAS rule

13+32=20

45=20

Bring the terms on one side

45-20=25 Answer

Answer:

false

Step-by-step explanation:

use bidmas :)

ok, let's rewrite this for b = 5

65 ÷ 5 + 8 × 4 = 20

now put brackets

(65 ÷ 5) + (8 × 4) = 20

          (13) + (32) = 20

              13 + 32 = 45

                     45 ≠ 20

false

hope this helped and good luck!

Answer:

area = 220.5 ft²

Step-by-step explanation:

2(Length) + 2(10.5) = 63 feet

2L + 21 = 63

subtract 21 from each side of the equation:

2L = 42

divide both sides by 2:

L = 21 feet

area = L x W = 21 x 10.5 = 220.5 ft²

Answer:

A = 220.5 ft

Step-by-step explanation:

[tex]2(Length) + 2(10.5) = 63 feet\\[/tex]

[tex]2L + 21 = 63\\[/tex]

[tex]63 - 21[/tex]

[tex]2L = 42[/tex]

[tex]42/2[/tex]

L = 21 feet

[tex]A=l * w[/tex]

[tex]21 x 10.5 = 220.5 ft^{2}[/tex]

Answer:

3y+8=3y+8

Step-by-step explanation:

10+3y-2=4y-y+8

10+3y-2 combine 10 and -2 and you get 3y+8

4y-y+8 combine the 4y with the -y and you get 3y+8

3y+8=3y+8

Answer:

is a function with a slope that is not constant.

Step-by-step explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.

On the other hand, nonlinear function has a negative relationship and as such an increase in one variable (input variable) causes a decrease in the other variable (output variable) i.e the variables are inversely proportional.

This ultimately implies that, the graph of a nonlinear is a curved line and whose direction is constantly changing.

Hence, a nonlinear function is a function with a slope that is not constant. An example of a nonlinear function is a quadratic function or equation.

Answer: $46.08

Step-by-step explanation:

Find the surface Area of the box

the bases are 12*12= 144 times 2 bases 144*2= 288

The area of each side is 12*18=216 times 4 sides 216*4=864

add the totals together to find the total surface area 288+864=1152

total surface area is 1152 inches. Multiply by the cost per square inch

1152*.04= 46.08

https://brainly.com/question/22920148?answering=true&answeringSource=feedPublic%2FhomePage%2F1

Step-by-step explanation:

[1] … … 2x₁ + 0x₂ + 3x₃ = 3

[2] … … 4x₁ - 3x₂ + 7x₃ = 5

[3] … … 8x₁ - 9x₂ + 15x₃ = 10

Since [1] is already free of x₂, you might as well start by eliminating x₂ from the other two equations. Add -3 times [2] to [3] :

-3 (4x₁ - 3x₂ + 7x₃) + (8x₁ - 9x₂ + 15x₃) = -3 (5) + 10

-12x₁ + 9x₂ - 21x₃ + 8x₁ - 9x₂ + 15x₃ = -15 + 10

-4x₁ - 6x₃ = -5

[4] … … 4x₁ + 6x₃ = 5

Now eliminate x₃ in [1] and [4]. Add -2 times [1] to [4] :

-2 (2x₁ + 3x₃) + (4x₁ + 6x₃) = -2 (3) + 5

-4x₁ - 6x₃ + 4x₁ + 6x₃ = -6 + 5

0 = -1

which is a contradiction. This means the system has no solution.

Answer:

The ranking of the top three teams could occur in 720 ways.

Step-by-step explanation:

The order in which the teams are ranked is important, that is, for example, Oilers, Flames and Canucks is a different outcome of Oilers, Canucks and Flames. This means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In how many ways could the ranking of the top three teams occur?

Three teams from a set of 10. So

[tex]T = P_{(10,3)} = \frac{10!}{7!} = 720[/tex]

The ranking of the top three teams could occur in 720 ways.

Answer:

Area of Shaded Area = 18.3

Step-by-step explanation:

P.S - The exact question is -

Given - In the following diagram, a quarter circle has been constructed using an isosceles right triangle whose legs measure 8 inches.

To find - Which of the following represents the area of the shaded region, rounded to the nearest tenth of a square inch?

Proof -

We know that,

Area of a quarter circle = [tex]\frac{1}{4} \pi r^{2}[/tex]

Also,

We know that ,

Area of isosceles Triangle = [tex]\frac{1}{2}*Base*Height[/tex]

Now,

Given that,

Radius of quarter circle = 8 inches

Base of Isosceles Triangle = 8 inches

Height of Isosceles Triangle = 8 inches

∴ we get

Area of a quarter circle = [tex]\frac{1}{4} \pi (8)^{2}[/tex] = 16[tex]\pi[/tex]

Area of isosceles Triangle = [tex]\frac{1}{2}*8*8[/tex] = 32

Now,

Area of Shaded area = Area of a quarter circle - Area of isosceles Triangle

                                 = 16[tex]\pi[/tex] - 32

                                 = 50.265 - 32

                                 = 18.265 ≈ 18.3

⇒Area of Shaded Area = 18.3
