The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greater than 148 ​inches?

Answers

Answer:

The possible values of S are the values between 37 and 49. (Excluding 37 and 49)

Step-by-step explanation:

If the perimeter of the square must be greater than 148 inches but less than 196 inches.

And perimeter of a square = 4s

We intend to find the values of s such that:

148 < 4s

¹⁴⁸⁄₄ < ⁴ˢ/₄

37 < s

Also:

4s < 196

s < ¹⁹⁶⁄₄

s < 49

Therefore:

37 < s < 49.

The possible values of s are the values between 37 and 49. (Excluding 37 and 49.)

If the expression is expanded, what is the coefficient of x?

Coefficient of x =

Answers

Answer:

12

Step-by-step explanation:

Start by expanding the expression:

4(3x+5)

Distribute the 4 to each of the numbers in the parentheses

12x+20

The coefficient of x is basically what is being multiplied by x. In this scenario, we can expand 12x to be...

12*x

Which means that the coefficient of x is 12

12x+20

12x+20=0

12x=-20.

12÷12x=-20÷12

Find the area of the region that lies under the parabola y=5x - x^2, where 1≤x≤4. I would definitely like to see some work :)

Answers

Answer:

  16.5 square units

Step-by-step explanation:

You are expected to integrate the function between x=1 and x=4:

  [tex]\displaystyle\text{area}=\int_1^4{(5x-x^2)}\,dx=\left.\left(\dfrac{5}{2}x^2-\dfrac{1}{3}x^3\right)\right|_{x=1}^{x=4}\\\\=\dfrac{5(4^2-1^2)}{2}-\dfrac{4^3-1^3}{3}=37.5-21=\boxed{16.5}[/tex]

__

Additional comment

If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.

The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.

This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...

  area = 4.5 +3×4 = 16.5 . . . square units

70% of _____=42

Answers

Answer:

60

Step-by-step explanation:

70% of x = 42

.7x = 42

x = 42 ÷ .7

x = 60

Answer:

60

Step-by-step explanation:

We have, 70% × x = 42

or,

[tex]\frac{70}{100}[/tex] × x = 42

Multiplying both sides by 100 and dividing both sides by 70,

we have x = 42 × [tex]\frac{100}{70}[/tex]

x = 60

If you are using a calculator, simply enter 42×100÷70, which will give you the answer of 60

What is the value for x?

Answers

This is an equilateral triangle, so all angles are 60 degrees, we can set 8y + 12 equal to 60, and 7x + 4 = 60
To simplify 8y + 12 = 60, subtract 12 from both sides to get 8y = 48, divide both sides by 8 and you have y = 6
To simplify 7x + 4 = 60, subtract 4 from both sides to get 7x = 56, divide both sides by 7 and you have x = 8

Find the area of the shaded region. Use 3.14 as an approximation.​

Answers

Answer:

shaded area = 113.64 cm²

Step-by-step explanation:

To find the shaded area, subtract the area of the circle from the area of the triangle.

Area of a triangle = 1/2 x base x height

⇒ area of triangle = 1/2 x 25 x 21.4 = 267.5 cm²

Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)

From inspection, we can see that the diameter of the circle = 14 cm

Therefore, as the diameter = 2r, then r = 14 ÷ 2 = 7 cm

⇒ area of circle = 3.14 x 7² = 153.86 cm²

Shaded area = area of triangle - area of circle

⇒ shaded area = 267.5 - 153.86 = 113.64 cm²

In terms of x, what is the length of the side of a square whose area is represented by the expression 25x^2 + 40x + 16?​

Answers

Answer:

Step-by-step explanation:

25x2 − 40x + 16 = (5x)² - 2*5*4  + 4²      { (a - b)² = a² - 2ab + b² }

                          = (5x - 4)²                      { here a = 50 and b = 4}

Side of the square = 5x - 4 units

Part B:

25x2 − 16y2 = (5x)² - (4y)²         { a² - b² = (a + b) * (a - b) }

                    = (5x + 4y) * (5x - 4y)    { here a = 5x and b = 4y}

Dimensions of Rectangle: (5x + 4y) ; (5x - 4y)

Answer:

Step-by-step explanation:

25x²+40x+16=25x²+20x+20x+16

=5x(5x+4)+4(5x+4)

Which ratio is larger, 18/5 or 72/25 ?​

Answers

18/5. Multiply the 5 as many times as you need to to get to 25. Then as many times as you multiplied the bottom multiply the top the same so it would be 5 times on both sides making the ratio. 90/25

Answer:

Step-by-step explanation:

LCM of 5 and 25=25

Now,

18/5=18x5/5x5=90/25

72/25=72/25

Since 90/25>72/25

Hence,

18/5 is greater than 72/75

Solve for x. The problem is in the picture!!

Answers

Answer:

According to the given Attachment

we know sum of all angles in a triangle is 180° .

Sum of all angles in = 180°

On substituting the given value we obtain

➥ x + 61° + 70° + 61° = 180°

➥ x + 192° = 180°

➥ x = 180° - 192°

➥ x = -12°

So, the value of x is -12°

Step-by-step explanation:

[tex]x + 61 + 70 + 61 = 180(sum \: of \\ \: triangle) \\ \\ x + 192 = 180 \\ \\ x = 180 - 192 \\ \\ x = - 12[/tex]
