Answer:

Step-by-step explanation:

Let x represent the number of liters of 40% solution in the mix. Then the total amount of acid in the mix is ...

  0.40x +0.05(10-x) = 0.20(10)

  0.35x +0.5 = 2.0

  0.35x = 1.5

  x = 1.5/0.35 ≈ 4.3 . . . . liters of 40% solution

  10-x = 10 -4.3 = 5.7 . . .liters of 5% solution

Answer:

y=-8/5x+77/5

Step-by-step explanation:

The equation of line that passes through the points (4, 9) and (9, 1) is y=-8/5x+77/5. Hope it helps!

The equation of line passes through the points (4, 9) and (9, 1) will be;

⇒ y = - 8/5x + 77/5

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (4, 9) and (9, 1)

Now,

Since, The equation of line passes through the points (4, 9) and (9, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 9) / (9 - 4)

m = - 8 / 5

Thus, The equation of line with slope - 8/5 is,

⇒ y - 9 = - 8/5 (x - 4)

⇒ y - 9 = - 8/5x + 32/5

⇒ y = - 8/5x + 32/5 + 9

⇒ y = - 8/5x + 77/5

Therefore, The equation of line passes through the points (4, 9) and (9, 1) will be;

⇒ y = - 8/5x + 77/5

Answer:

m∠D = 14

Step-by-step explanation:

According to the vertical angle theorem, both of these angles are congruent.

This means that they are equal (m∠C = m∠D) and we can solve for x:

m∠C = m∠D

-x + 26 = 2x - 10 (substitute in the equations)

-3x + 26 = -10 (subtract 2x from both sides)

-3x = -36 (subtract 26 from both sides)

x = 12 (divide both sides by -3)

Now that we know what x is, we can find m∠D by plugging it back into the equation:

m∠D = 2x - 10

m∠D = 2(12) - 10 (substitute the value for x in)

m∠D = 24 - 10

m∠D = 14

The value of the variable 'x' will be 12. Then the measure of the angle D will be 14°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Angle C and angle D are vertical angles with m∠C = -x + 26 and m∠D = 2x - 10.

∠C = ∠D

-x + 26 = 2x - 10

3x = 36

x = 12

Then the measure of the angle D will be

m∠D = 2x - 10

m∠D = 2(12) - 10

m∠D = 24 - 10

m∠D = 14°

The value of the variable 'x' will be 12. Then the measure of the angle D will be 14°.

Answer:

x = 96

z = 25

Step-by-step explanation:

x and 84 are supplementary angles.

this means that they add together to make 180.

using this, you can make the following equation:

x + 84 = 180

subtract 84 from both sides of the equation

x + 84 - 84 = 180 - 84

x = 180 - 84

x = 96

84 and 3z + 9 are vertical angles

vertical angles are equal.

using this, you can make the following equation:

84 = 3z + 9

subtract 9 from both sides of the equation

84 - 9 = 3z

75 = 3z

divide both sides of the equation by 3

75/3 = 3z/3

25 = z

Given:

[tex]y=x^2+6x-1[/tex]

[tex]\dfrac{x}{r}=-3[/tex]

To find:

The given equation in terms of r if [tex]\dfrac{x}{r}=-3[/tex].

Solution:

Given that,

[tex]\dfrac{x}{r}=-3[/tex]

[tex]x=-3r[/tex]

We have,

[tex]y=x^2+6x-1[/tex]

Substitute x=-3r in the above equation.

[tex]y=(-3r)^2+6(-3r)-1[/tex]

[tex]y=9r^2-18r-1[/tex]

Therefore, the required equation in terms of r is [tex]y=9r^2-18r-1[/tex].

Answer:

she needs 3 packages

Step-by-step explanation:

the total area of the cd is 27 cm

so like

she needs to wrap 27 cm of area

because 0.5 cm by 14 cm by 12.5 cm added all together is 27

then

27 cm equals 10.6 inches

so now we need to find how many 300cm2 will fit into that 11 inch space

There are 0.00107639 square feet in a square centimeter.

but we want to know how many feet not square feet

0.00107639 × 27 =

0.02906253

2.906253

there are 2.906253 feet per suare foot

so 2.9 rounded up is 3

Step-by-step explanation:

For solving the Equation, we need to simplify it first. Expanding the parentheses.

⇒ -4w - 4 = -24 w

Shifting -24 w to the LHS to isolate m and shifting 4 to the RHS[tex].[/tex]

⇒ -4w + 24w = 4

⇒ 20w = 4

Dividing the equation by 20, So that we will get w in the LHS of the equation.

⇒ w = 4/20

⇒ w = 1/5

The required value of w is 1/5.
