Answer:

200 sheets are required

Step-by-step explanation:

We need to calculate the area of both the sheets and the wall

Mathematically,

area of a rectangle = l * b

Area of the sheet = 20 * 50 = 1,000 cm^2

100cm = 1 m

so the area of the wall is 400 by 500 = 200,000 m^2

To know the number of sheets, we now divide the area of the wall by that of the sheet

Mathematically, that will be;

200,000/1,000 = 200 sheets

Answer:

option A)  y > 5/4x + 10

Step-by-step explanation:

Take any point in the shaded region

( -12 , 1)

y > 5/4 x + 10

1 > 5/4 * (-12) + 10

1 > 5*(-3) +10

1 > -15 + 10

1 > -5

(-12 , 5) satisfies the equation.

Answer:

DE ≈ 40

Step-by-step explanation:

Using the Sine rule in Δ DEF

∠ D = 180° - (58 + 87)° ← sum of angles in a triangle

∠ D = 180° - 145° = 35° , then

[tex]\frac{DE}{sin87}[/tex] = [tex]\frac{EF}{sin35}[/tex] = [tex]\frac{23}{sin35}[/tex] ( cross- multiply )

DE × sin35° = 23 × sin87° ( divide both sides by sin35° )

DE = [tex]\frac{23sin87}{sin35}[/tex] ≈ 40 units ( to the nearest whole number )

Step-by-step explanation:

Read the poem. excerpt from “Spring” by Christina Rossetti Frost-locked all the winter, Seeds, and roots, and stones of fruits, What shall make their sap ascend That they may put forth shoots? Tips of tender green, Leaf, or blade, or sheath; Telling of the hidden life That breaks forth underneath, Life nursed in its grave by Death. Which line from the poem contributes most to a hopeful tone? "Telling of the hidden life" "Frost-locked all the winter," "Life nursed in its grave by Death." "What shall make their sap ascend"

The numbers are 25, 34, and 17.

Let x be the first number, y be the second number, and z be the third number. We know that x + y + z = 76, z = x - 8, and y = 2z.

Substituting the second and third equations into the first equation, we get x + 2(x - 8) + (x - 8) = 76.

Simplifying the right side of the equation, we get 4x - 24 = 76.

Adding 24 to both sides of the equation, we get 4x = 100.

Dividing both sides of the equation by 4, we get x = 25.

Substituting x = 25 into the equation z = x - 8, we get z = 25 - 8 = 17.

Substituting x = 25 and z = 17 into the equation y = 2z, we get y = 2 * 17 = 34.

Therefore, the numbers are 25, 34, and 17.

Answer:

The inequality correctly matches the graph is -2 < x < 4 ⇒ B

Step-by-step explanation:

From the given figure

∵ There is a segment drawn from -2 to 4

∴ The starting point of the inequality is -2

∴ The ending point of the inequality is 4

∵ The endpoints of the segments are white circles (not shaded)

→ That means the signs of inequality without sign =

∴ The values of x are between -2 and 4

∴ The inequality is -2 < x < 4

∴ The inequality correctly matches the graph is -2 < x < 4

Answer:

Y= [tex]\frac{-2x+6}{3}[/tex]

Step-by-step explanation:

slope intercept formula is

Y=mx+b

Now we want the y isolate so in this case we just subtract 2x on both sides

3Y=6-2x

or in more better terms

3y=-2x+6

Now we want the 3 isolated so we divide 3 on both sides

and you’ll get

[tex]\frac{-2x+6}{3}[/tex]

Answer:

Step-by-step explanation:

Using the midpoint theorem, the perimeter of the triangle formed by joining the midpoints of the original triangle is exactly half the size in perimeter

What we mean in this case is that the perimeter of BAC IS two times the perimeter of EDF

perimeter of EDF is the sum of all the sides = 2 + 4 + 3 = 9

So the perimeter of BAC is 2 * 9 = 18

Step-by-step explanation:

I assume you mean an expression with exponents.

In the future, for a to the n power use a^n.

Recall the following two rules of exponents:

[tex] x^a \times x^b = x^{a + b} [/tex]

[tex] (x^a)^b = x^{ab} [/tex]

Now we can answer your question.

[tex] (x^{22})(x^7)^3 = [/tex]

[tex]= (x^{22})(x^{21})[/tex]

Answer:

$160

Step-by-step explanation:

Diane sold some stuffs at a garage sale.

Let the total value of the money Diane made = x

She spent one-half of the money she made on a new bicycle.

Amount spent on a Bicycle = 1/2 × x = 1/2x

Next,

Amount left

= x - 1/2x = 1/2x

She spent one-half of what was left on a portable stereo.

Amount spent spent on Portable stereo

= 1/2 × 1/2x

= 1/4x

If Diane had $40.00 left,

Hence:

The fraction of what was left is calculated as:

= x - (1/2x + 1/4x)

= x - (3/4x)

= 1/4x

Hence:

1/4x = $40

We can find the value of x now.

1/4 × x = $40

x/4 = $40

x = $40 × 4

x = $160

Therefore, the amount she made from the garage sale is $160
