Answer:

B. 53

Step-by-step explanation:

7 to the power of 2 is simply 7 x 7. And 2 to the power of 2 is 2 x 2. Together you have 49 and 4 which makes 53 the simplified form of your equation.

let

width = w

length = 4w + 11

2(length) + 2(width) = perimeter

2(4w + 11) + 2(w) = 162

8w + 22 + 2w = 162

10w + 22 = 162

10w = 140

w = 14 cm (WIDTH)

length = 4w + 11

length = 4(14) + 11

length = 56 + 11

LENGTH = 67 cm

The length is 4(14)+ 11 = 67 cm and width is 14 cm.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Perimeter of rectangle = 162 cm

let the width be x .

then, the length is 4x+ 11

Thus, Perimeter of rectangle= 2(l + w)

162 = 2( 4x + 11 + x)

162 = 2( 5x +11)

81 = 5x+ 11

5x= 70

x= 14

Hence, the length is 4(14)+ 11 = 67 cm and width is 14 cm.

Answer:

Matt was paid an average of $10 per hour of babysitting for the day.

Step-by-step explanation:

He babysat in the morning for 3 hours being paid $10 per hour. He later babysat in the evening for 5 hours being paid $20 per hour. Since he was being paid two different amounts throughout the day, the average would be $10. He was being paid atleast $10 per hour for babysitting because even though he was being paid $20 in the evening, the lowest amount of money that he was paid, was $10 making that the average.

Answer:

Hypotenuse = 37

Step-by-step explanation:

Let the base is 12 and height is 35.

We can use Pythagorean theorem to find the third side (hypotenuse or the longest side). The Pythagoras theorem can be given by :

[tex]H^2=b^2+h^2\\\\H^2=12^2+35^2\\\\H^2=1369\\\\H=\sqrt{1369} \\\\H=37[/tex]

Hence, the hypotenuse is 37 units.

Answer:

X=2, AB=14, DC=14

Step-by-step explanation:

3x+8=x+12

Subtract x from both sides

2x+8=12

Subtract 8 from both sides

2x=4

Divide by 2 on the sides

Answer: x=2

Then replace the x's with (2) and multiply

3(2)+8 and (2)+12

Answer:

Both AB and DC are equal to 14.

Answer:

(x-  5)(x - 3)

x(x - 3) -5(x - 3)

x^2 - 3x - 5x + 15

x^2 - 8x + 15

-1/2x > 6

All you have to do is divide 6 by -1/2, which is -3. The answer is x < -3, the sign got flipped because you divide by a negative number.

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

First, subtract the numbers in the parentheses, then multiply by 11.

(12 - 9) = (3)

3 x 11 = 33

19 + 11 - 12^2 ÷ 3(33) - 7

Now, just multiply 33 by 3, and then square 12 (12 x 12).

19 + 11 - 144 ÷ 99 - 7

Now, you can divide 144 by 99, this is an infinite number, so..

144 ÷ 99 = 1.455

19 + 11 - 1.455 - 7

Finally add, then subtract.

30 - 1.455 - 7

28.545 - 7

The final answer is 21.545.

Answer:

t=1

Step-by-step explanation:

16-2t = t + 9 +4t

combine like terms

16-2t = 5t + 9

add 2t to both sides

16-2t+2t = 5t+9+2t

combine like terms

16=7t+9

subtract 9 from both sides

16-9=7t+9-9

combine like terms

7=7t

divide both sides by 7

t=1

Answer:

16=t+9+4t+2t

16=9+7t

16-9=7t

7=7t

t=1

Answer:

R'(-3,-1), S'(-1,-3), T'(-4,'5).

Step-by-step explanation:

Rotations

Rotating a point of coordinates M(h,k) through 180° about the origin maps it to coordinates to M'(-h, -k).

The triangle has the vertices at R(3,1), S(1,3), T(4,5). After a rotation of 180° about the origin it maps to a new triangle with coordinates:

R'(-3,-1), S'(-1,-3), T'(-4,'5).

An image of both triangles is shown below.

Answer:

x- intercept (5, 0)

y- intercept (0, 2)

Step-by-step explanation:

x- intercept occurs at y= 0.

To find the x- intercept of the linear equation, substitute y= 0 into the equation.

4x +10y= 20

When y= 0,

4x +10(0)= 20

4x= 20

x= 20 ÷4 (÷4 on both sides)

x= 5

Thus, the x-intercept is (5, 0).

y-intercept occurs at x= 0.

4x +10y= 20

When x= 0,

4(0) +10y= 20

10y= 20

y= 20 ÷10 (÷10 on both sides)

y= 2

Thus, the y-intercept is (0, 2).
