A nurse mixes 60 cc of a 70% saline solution with a 20% saline solution to produce a 25% saline solution. How much of the 20% solution should he use
A yoga studio offers memberships that cost $20 per month for unlimited classes. The studio
also accepts walk-ins, charging $5 per class. If someone attends enough classes in a month,
the two options cost the same total amount. How many classes is that?
Answer:
4
Step-by-step explanation:
Each walk-in is $5, so 20 divided by 5 is 4. 4 classes.
-2x - 35 = 9 - 4x answers
Answer:
22
Step-by-step explanation:
add 35 to the other side (to cancel out the negative) then you have 44, then add 4x to the other side so you have 2x then divide both sides by 2. x=22

Answer:
The correct option is;
An isosceles trapezoid with legs of length 8
Step-by-step explanation:
The correct option is an isosceles trapezoid with legs of length 8
The given properties of the quadrilateral are;
1) One pair of equal opposite sides
2) One pair of parallel opposite sides
From the given options, the two options which are not parallelograms are the kite and the trapezoid
However given that the option of the kite has a pair of adjacent side of length 8, with the given pair of equal length opposite side of length 8, we have that all the sides of the quadrilateral will be of length 8, and the figure cannot be a kite
An isosceles trapezoid of leg length 8 has one pair of equal length opposite sides of length 8 and one pair of parallel sides of unequal length
Given that the length of the lines that make up the pair of opposite parallel sides in the figure are not specified, the figure can be described by as being an isosceles trapezoid.

Answer:
Equation of Parallel line: y = -5x-34Equation of Perpendicular line: y = 1/5x - 14/5Step-by-step explanation:
a) Equation of Parallel line to the given line and passes through the point (-6, -4)
We know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Given the line
y = -5x+4
comparing with the slope-intercept form of the line equation
The slope of the line = m = -5
We know that parallel lines have the same slope. Thus, the slope of the line parallel to the line y = -5x+4 will also be: -5
So, the equation of the line parallel to the given line and passes through the point (-6, -4) will be:
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -5 and the point (-6, -4)
y - (-4) = -5(x-(-6))
y+4 = -5(x+6)
y+4 = -5x-30
y = -5x-30-4
y = -5x-34
Therefore, the the equation of the line parallel to the given line and passes through the point (-6, -4) will be:
y = -5x-34Hence:
Equation of Parallel line: y = -5x-34
a) Equation of Parallel line to the given line and passes through the point (-6, -4)
Given the line
y = -5x+4
comparing with the slope-intercept form of the line equation
The slope of the line = m = -5
We know that a line to perpendicular another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
The slope of new line = – 1/m = -1/-5 = 1/5
So, the equation of the line perpendicular to the given line and passes through the point (-6, -4) will be:
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/5 and the point (-6, -4)
y - (-4) = 1/5 (x-(-6))
y+4 = 1/5 (x+6)
Subtract 4 from both sides
[tex]y+4-4=\frac{1}{5}\left(x+6\right)-4[/tex]
[tex]y=\frac{1}{5}x-\frac{14}{5}[/tex]
Therefore, the equation of the line perpendicular to the given line and passes through the point (-6, -4) will be:
[tex]y=\frac{1}{5}x-\frac{14}{5}[/tex]
Hence:
Equation of Perpendicular line: y = 1/5x - 14/5

Step-by-step explanation:
The school that Chelsea goes to is selling tickets to a choral performance. On the first day of
ticket sales the school sold 8 adult tickets and 7 child tickets for a total of $133. The school took
in $132 on the second day by selling 9 adult tickets and 2 child tickets. Find the price of an adult
ticket and the price of a child ticket.
Answer:
Adult: $14 each
Child: $3 each
Step-by-step explanation:
Day 1: (14*8)+(3*7) = 112+21 = 133
Day 2: (14*9)+(3*2) = 126+6 = 132
1. A piece of wire that is 28 inches long is cut into two pieces, each of which is then bent into the shape of a
square. The larger square has side lengths that are three inches longer than the smaller square.
(a) If x is the side length of the smaller square and y is the side length of the larger square, write a system of
equations that models this scenario.
(b) Solve the system of equations and determine the lengths of the two pieces of wire.
Answer:
1: So one side is 5
2: Other side is 2
Step-by-step explanation:
1)
4(x+3)+4x=28
Solve
4x+12+4x=28
Combine
8x+12=28
Isolate
8x=16
Isolate
x=2
Substitute
4(2+3)=20
4*2=8
Now find each side
20/4=5
8/4=2

Answer:
11
Step-by-step: When you combine the dots from 3, 4, 5, and 6 you get 11 total
Answer:
That would be 11 my good sir :) (or ma'am)
Step-by-step explanation:
starting from 3 movies we have 4 possible outcomes: 3, 4, 5, and 6.
We have 6 of the 20 students, who watched 3 movies over the break.
Out of the 20 students, 4 watched 4 movies over the break.
Out of the 20 students, none watched 5 movies over the break.
Lastly, 1 student watched up to 6 movies on the break.
Adding up all the students who watched 3 or more movies on the break, we get 11.
1 + 0 + 4 + 6 = 11

Find the base hei ght when the volume is 10,125 cubic meters.
Answer:
15 m
Step-by-step explanation:
cross-section area=1/2×45×x m ²
height = 30 m
volume=10125m³
we have
volume = cross-section area×height
10125 = ½×45×x×30
x=10125×2/(45×30)
x=15m

Find the equation of the line that passes through both (5,1) and (8,-2)
Let [tex]f(x) = ax+b[/tex] be the line that passes through both points.
We know that [tex]f(5) = 1[/tex] and [tex]f(8) = -2[/tex]. So:
[tex]\begin{cases}5a+b = 1 \\ 8a+b = -2\end{cases}[/tex]
Solving the system, we get that a= -1 and b = 6.
So the line is equal to [tex]f(x) = 6-x[/tex].
Use the diagram of ◾ABC to find m<D
M<D=
Answer:
In quadrilateral ABCD we have
AC = AD
and AB being the bisector of ∠A.
Now, in ΔABC and ΔABD,
AC = AD
[Given]
AB = AB
[Common]
∠CAB = ∠DAB [∴ AB bisects ∠CAD]
∴ Using SAS criteria, we have
ΔABC ≌ ΔABD.
∴ Corresponding parts of congruent triangles (c.p.c.t) are equal.
∴ BC = BD.

Mr. Paulsen challenges Olivia and Angelica to move figure ABCDE onto figure
A'B'C'D'E' using a series of two different transformations. They give two different
answers
Answer the questions to investigate ways to transform ABCDE
1. Olivia finds a combination of two different transformations that moves ABCDE
onto A'B'C'D'E' What is one way she might have done this?
Write your answer in the space below.
Answer:
Step-1 : Reflect the original figure around the x-axis.
Step-2 : Slide the new figure 7 units to the right.
Answer:
Olivia finds a combination that moves figure ABCDE onto figure A"B"C"D"E".
She may have reflected it over the x-axis and then translated it right 10 units.
Angelica reflected the figure over the y-axis and translated it up 8 units. Her transformed figure is in the correct location, but facing the wrong direction
