One antifreeze solution is 26% alcohol and another is 11% alcohol how much of each mixture should be added to make 24 l of a solution tgat is 21% alcohol?
Answer:
Step-by-step explanation:
One antifreeze solution is 26% alcohol and another is 11% alcohol how much of each mixture should be added to make 24 l of a solution that is 21% alcohol?
Let us represent
First solution =>x
Second solution => y
System of equations
x + y = 24.....Equation 1
x = 24 - y
26% × x + 11% × y = 21% × 24
= 0.26x + 0.11y = 5.04... Equation 2

The box plot show the price of textbooks at a local high school. What range describe the middle 50% if the price (p) of the textbooks?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the box plot is not attached.
However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores
To answer this question, I will make use of the attached box plot.
IQR is calculated as:
[tex]IQR = Q_3 - Q_1[/tex]
[tex]Q_1[/tex] and [tex]Q_3[/tex] are represented by the vertical edges of the rectangle in the box plot. [See attachment]
Reading [tex]Q_1[/tex] and [tex]Q_3[/tex], we have:
[tex]Q_1 = 37[/tex]
[tex]Q_3 = 50[/tex]
The IQR is:
[tex]IQR = 50 - 37[/tex]
[tex]IQR = 13[/tex]
Hence, the range that describes the middle 50% of the attached plot is 13

Answer:
x = 8
Step-by-step explanation:
Using the sine or cosine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{x}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
x = 8
I have a 45, 45, 90 right triangle. The hypotenuse is 10 units long. How long are the legs?
a) 5 units
b) √10 units
c) 5 √2
d) one is 5 units s and the other is 5 √3
Answer:
C
Step-by-step explanation:
The triangle follows the pattern:
45 - 45 - 90
x - x - xsqrt(2)
Since you already have the hypotenuse (90), you need to divide by sqrt(2) to get the legs.
[tex]\frac{10}{\sqrt{2} } = \frac{10\sqrt{2} }{2} = 5\sqrt{2}[/tex]

C

Given:
EFGH is a square.
To find:
The [tex]m\angle FHG[/tex].
Solution:
We know that all interior angles of a square are right angles.
[tex]m\angle EHG=90^\circ[/tex] (Right angle)
The diagonals of square are always the angle bisectors.
FH is a diagonal of the square. So, it bisects the angle EHG.
[tex]m\angle FHG=\dfrac{m\angle EHG}{2}[/tex]
[tex]m\angle FHG=\dfrac{90^\circ}{2}[/tex]
[tex]m\angle FHG=45^\circ[/tex]
Therefore, the measure of angle FHG is 45 degrees.

Shanice's school made $850 by selling 125 tickets to the annual talent show. They sold adult
tickets for $10 and student tickets cost $6. How many adult tickets did they sell? How many
student tickets did they sell?
Write a system of equations to represent this situation. Define your variables.
Answer:
25 adult tickets were sold and 100 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be x and the number of student tickets sold be y.
We know that the total amount collected from the tickets was $850, and that a total of 125 tickets were sold. We can use this information to come up with two equations.
10x + 6y = 850 - Equation 1
x + y = 125 - Equation 2
Then, use the substitution method to solve for either x or y first, followed by the other.
From equation two:
x + y = 125
x = 125 - y - Equation 3
Sub eqn 3 into eqn 1:
10(125-y) + 6y = 850
1250 - 10y + 6y = 850
1250 - 4y = 850
-4y = - 400
y - 100
Sub y = 100 into eqn 2:
x + 100 = 125
x = 25
Check:
10(25) + 6(100) = 850

the area of a square is 625cm squared. What is the measurement of the diagonal to the nearest tenth.
Answer:
diagonal = 35.4
area = s²
√625 = 25
side = 25
diagonal² = 25² + 25² = 625 + 625 = 1250
diagonal = √1250 = 35.4
