At the grocery store last week, small boxes of facial tissue were on sale at 4 boxes for $5. This week they mark a new price at 5 boxes for $4. What is the percent decrease in the price per box this week?
Answer: 36%
Step-by-step explanation:
Since the price last week, was 4 boxes for $5. Therefore, the price per box will be:
= $5/4
= $1.25 per box
This week they mark a new price at 5 boxes for $4. The price per box will be:
= $4/5
= $0.8 per box
The percent decrease in the price per box this week will be:
= (1.25 - 0.80)/1.25 × 100
= 0.45/1.25 × 100
= 36%
The Percentage decrease is 36%
Which is the graph of y - 3 = -2/3(x + 6)?
Answer:
Step-by-step explanation:
y - 3 = -2/3(x + 6) Remove the brackets on the right
y - 3 = -2/3x - 2/3 * 6 Simplify the right
y - 3 = -2/3x - 4 Add 4 to both sides
y = - 2/3 x - 1
I'm going to enclose the graph. Pick the one that has a y intercept at (0,-1) and and an x intercept of (-1.5, 0)goes from the lower right to the upper left as the graph below shows.
Which system of equations has infinitely many solutions?
Using the Pythagorean Theorem, find the distance between the points.
Answer:
(5,7,8.6)
Step-by-step explanation:
Create a line on each the x axis and the y axis which intersects at a right triangle. The x axis line is 7 squares and the y axis is 5 squares. Now you can use the Pythagorean theorem.
a^2+b^2=c^2
7^2+5^2=c^2
49+25=c^2
74=c^2
8.6=c

6. If the set A = {-2, 1, 3), then the set A is a subset of the set of?
Answer:
Step-by-step explanation:
We could invent set B: {-2, 1, 3, 5, 6, 10} and then correctly state tht set A is a subset of B, because {-2, 1, 3} is also found in A.

Hope it is helpful...Work out m and c for the line: y = 4 x − 1
Answer:
m=4 and c=-1
Step-by-step explanation:
I'm assuming that m is the slope and c is the y-intercept. (If this is not the case, please tell me and I'll fix my answer).
The equation is already in the form y=mx+c so you just take the numbers from the problem y=4x-1.
Answer:
m = 4 c=-1
Step-by-step explanation:
The slope form is y = mx + b.
M is the slope which is 4.
B is the y=intercept which is -1.

Answer:
QSR = 68º
Step-by-step explanation:
TSQ + QSR = TSR
15x + (10x - 2) = 173
Combine like terms
25x = 175
Divide both sides by 25
x = 7
QSR = 10x - 2
QSR = 10(7) - 2
QSR = 68º
Si: Tg θ =√2 ∧ θ es agudo √7 Calcular: A = 3(Sen θ + Cos θ) - √7
Answer:
[tex]A \approx 1.488[/tex]
Step-by-step explanation:
Por definición de razones trigonométricas, tenemos las siguientes identidades:
[tex]\tan \theta = \frac{y}{x} = \sqrt{2}[/tex] (1)
[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
[tex]\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (3)
Si [tex]\theta[/tex] es agudo, entonces [tex]x, y > 0[/tex].
De (1), suponemos [tex]x = 1[/tex] que [tex]y = \sqrt{2}[/tex], entonces los valores de las funciones seno y coseno:
[tex]\sin \theta = \frac{\sqrt{2}}{\sqrt{5}} = \sqrt{\frac{2}{5} }[/tex]
[tex]\sin \theta = \frac{\sqrt{10}}{5 }[/tex]
[tex]\cos \theta = \sqrt{\frac{1}{5} }[/tex]
[tex]\cos \theta = \frac{\sqrt{5}}{5}[/tex]
Por último, calculemos [tex]A[/tex]:
[tex]A = 3\cdot \left(\frac{\sqrt{10}}{5} + \frac{\sqrt{5}}{5} \right) - \sqrt{7}[/tex]
[tex]A \approx 1.488[/tex]
A sum of money is shared between 2 friends in the ratio 2 : 3. If the larger
share is $450. What is the total sum shared?
Answer:
$750
Step-by-step explanation:
Larger share = $450
Smaller share : Larger share :: 2 : 3
Smaller share = (larger share x 2) / 3
= (450x2)/3
= 300
Sum= larger share + smaller share
= $450 + $300 = $750

what do you need help with?
Step-by-step explanation:
Write an equation in
slope-intercept form that
passes through (-6, -2)
and has a y-intercept
located at y= -5
Answer:
y = -1/2 x -5
Step-by-step explanation:
The slope intercept form of an equation is
y = mx+b where m is the slope and b is the y intercept
We know b
y = mx-5
Substitute the values of x and y into the equation to determine the slope
-2 = m(-6) -5
Add 5 to each side
-2+5 =-6m
3 = -6m
Divide by -6
3/-6 = m
The slope is -1/2
y = -1/2 x -5

Answer:

Step-by-step explanation:
It is easier to construct the center using a compass and straightedge (and pencil). The center is where the medians meet. A median is drawn from a vertex to the midpoint of the opposite side.
A ruler can be used. It is easier if it combines full- and half-scale markings on the same edge. This will let you find the midpoint of a side quickly.
With a compass and straightedge, the usual process of constructing the bisector of a line segment is used.
Wich Type of rectangle has not equal side lengths A. Isosceles B. Equilateral C. Scalene D. None of the above
Answer:
C. Scalene triangle
Step-by-step explanation:
Wich Type of triangle has not equal side lengths A. Isosceles B. Equilateral C. Scalene D. None of the above
scalene triangle can be regarded as triangle whereby all three sides of the triangle have different lengths. the angles in scalene triangle is also
different if measured. Some right triangles can as well be regarded as scalene triangle if other two angles( the legs) are not congruent. It should be noted that Type of triangle which has not equal side lengths is Scalene

If 50 kg of rice cost Rs 375,how much can be purchased for Rs.525?
Answer:
70kg can be purchased for Rs 525
Step-by-step explanation:
Let the quantity of rice that can be bought with Rs 525 be = x
Rice ( kg) Cost (Rs)
50 375
x 525
[tex]\frac{50}{x} = \frac{375}{525} \\\\x \times 375 = 50 \times 525\\\\375x = 26250\\\\x = \frac{26250}{375} = 70 \ kg[/tex]
Therefore 70kg rice can be purchased for Rs. 525
