A scientist needs 10 liters of a 20% acid solution for an experiment, but she only has a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and 40% solutions should she mix to get the solution she needs?
9514 1404 393
Answer:
4.3 L of 40% solution5.7 L of 5% solutionStep-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
Angle C and angle D are vertical angles with m angle C = -x + 26 and m angle D = 2x - 10.
What is m angle D?
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°.
What is an angle?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°.

I NEED HELP ASAP PLEASE!! -4(w+1)=-24 w= what?
GiveN:
-4(w + 1) = -24wWhat to do?
We have to solve for wStep-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.

The width of a rectangle is 12 cm less than the length the perimeter is 156 cm. Which equations represents how to find the length and the width?
Answer:
x+x+x+12+x+12=156
width is 33
length is 45
Step-by-step explanation:
for for the width we will substitute it for x, and for the length we will substitute for x + 12 since the width is 12 cm less than the length. and, we know that to find the perimeter, you just have to add the widths and lengths. and since the perimeter is given the equation is:
x+x+x+12+x+12=156
width is 33
length is 45

If wrapping paper comes in packages of 300 cm2. How many packages will Sally need?
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
she needs 3 packages

Write the equation of the line that passes through the points (4,9) and (9,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
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
What is Equation of line?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
