A dinner plate is in the shape of an isosceles right triangle. The leg length is 13 inches. What is the perimeter of the plate? Round your answer to the nearest tenth.

Answer:

[tex]Question \: 1: \: let \: the \: question \: mark \: be \: n \\ n = 63 \\

Question \: 2: \: the \: error \: the \: student \: made \: is \: \\ 4x + 40 = 6x - 10 \: insteade \: of : \\ 4x + 40 + 6x - 10 = 180. \\

Question \: 3: \: x = 15 \\

Question \: 4: m( GFC)

= 80. \\ [/tex]

Step-by-step explanation:

[tex]let \: the \: unknown \: be \: n \\ then \\ 87 + n = 150 \\ n \: = 150 - 87 = 63. \\ the \: mistake \: is \: by \: the \: expression : \\ 4x + 40 = 6x - 10 \: insteade \: of : \\ 4x + 40 + 6x - 10 = 180. \\ 10x = 150 \\ x = 15. \\ 6x - 10 = 6 \times 15 - 10 \\ GFC

= 80. \\ [/tex]

Answer:

$345

Step-by-step explanation:

108+86+101+52=347

347 rounded to the nearest 5 is 345

so x^2-10=0

we add 10 to both sides of the equation  x^2 = 10

then take the square root of both sides of the equation to eliminate the exponent on the left side  x = ± √10

The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10

the result can be shown in multiple forms

Exact Form :x=√10,−√10x=10,-10

Decimal Form: x=3.16227766…,−3.16227766

Answer:

(-5)^3 = -125

Step-by-step explanation:

(-5)^3

= (-5) × (-5) × (-5) = -125

= (-5)^3 = -125

(-5) to the power of 3 is just (-5) multiplied by itself 3 times so (-5) to the power of 3 is (-5)^3 which is -125

Step-by-step explanation:

it's quite easy to go around this problem.

first you gotta consider the negative (-) sign..

you know when a negative sign multiplies another negative sign you'll get a positive sign.

example

-5*-5= ?

since you know the negative sign would turn to a positive sign when they multiply each other.

and be mindful of problems with different signs like

−6×9, you'll definitely get a negative answer

Now to your question.

(−5)^3, if you're struggling with composite expression,all you need is to break it down to simplified form

since it's -5 raised to the power of 3

you can as well write it as -5*-5*-5 (pay attention to the negative sign). then go through with your calculations

if you do it correctly, you'll arrive at the answer

-125

Answer:

No.

Here's the break why it is not proportional...

[tex]3*4 = 12\\6*4=24\\9*4=36\\8*6=48\\10*6=60[/tex]

The proportion breaks near the end because the multipliers no longer match.

Answer:

It is not proportional

Step-by-step explanation:

12 apples=$3                 60 apples=$10

/3               /3    But...     /10                /10

4 apples=$1                    6 apples=$1

The price went down so it's not proportional

210 - 210 x 16% = 210 x 84% = 176,40

Answer: 131

Step-by-step explanation:

Vertical angles are congruent.

Answer:

Step-by-step explanation:

Common difference = 2nd term - 1st term = 11 - 5 = 6

a = 5

nth term = a + (n-1)d

               = 5 +( n-1) * 6

              = 5 + 6n - 6

             = 5 - 6 + 6n

              = 6n - 1

Answer:

x=10

Step-by-step explanation:

2(x − 3) = 14

2x+2 . -3 = 14

2x-16=14

2x-6+6=14+6

2x=14+6

2x=20

divide both sides by 2

Answer:

-(1+x-y)(x-y-1)

Step-by-step explanation:

since both terms are perfect squares, factor using the difference of squares formula

a2 - b2 = (a+b) (a-b) where a = 1 and b= x-y

-(1+x-y)(x-y-1)

Answer:Factor by grouping.

Step-by-step explanation:

Answer:

let [tex]x[/tex] = height of rectangle

Given:

Therefore,

Shaded area = area of rectangle - area of circle

Area of rectangle = length × height

                             = [tex]3x \times x[/tex]

                             = [tex]3x^2[/tex]

Area of circle = [tex]\pi r^2[/tex]

                       [tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]

                       [tex]=\dfrac14\pi x^2[/tex]

[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]

If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm

Substituting [tex]x = 4[/tex] into the equation:

[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]

[tex]\implies \textsf{shaded area}=48-4\pi[/tex]

[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]

Answer: quotient is 20 up top number is

141 (R 20)

Step-by-step explanation:

Drop the three and you have 133.

What times 32 is 133

32 times four is 128

Now do 133 - 128 = 5

Drop the 2

What times 32 is 52

Well times two is 64 so it has to be times1

Now you have 52 - 32 to get your quotient of 20

Step-by-step explanation:

The number of 5ths that equals 9 is gotten bus using multiplication property of equality by multiplying 9 by 5 to give; 45

We want to find the number of 5ths that equals 9. We can express this as;

¹/₅x = 9

Where x is the number that is multiplied with one - fifth to equal 9.

To solve it, we will apply multiplication property of equality by multiplying both sides by 5 to get;

x = 45

Thus, the number of 5ths that equals 9 is 45.
