The midpoint of AB‾AB is M(−4,−3)M(−4,−3). If the coordinates of A are (−1,-2)(−1,−2), what are the coordinates of B?
Answer:
(-7, -4)
Step-by-step explanation:
The midpoint formula is expressed as;
M (X,Y) = {(x1+x2/2), (y1+y2)/2}
Given that M(-4, -3) and (x1, x2) = (-1, -2)
X = x1+x2/2
-4 = -1+x2/2
-8 = -1 + x2
x2 = -8 + 1
x2 = -7
SImilarly;
Y = y1+y2/2
-3 = -2+y2/2
-3*2 = -2+y2
-6 = -2 + y2
y2 = -6 + 2
y2 = -4
Hence the coordinate of B is (-7, -4)

A trinket factory can produce 3000 trinkets per day the. warehouse has a capacity of 50000 trinkets .currently there are 8000 trinkets in the warehouse assume that no trinkets are going to be shipped out of the warehouse for a while
Answer:
14 days
Step-by-step explanation:
Since there are already 8000 trinkets in the warehouse, this means that we need to find the number of days it will take for the factory to create 42,000 trinkets which would cause the warehouse to max out it's capacity.
50,000 - 8000 = 42,000 trinkets
Since the factory can produce 3000 trinkets per day, we simply need to divide 42,000 by 3000 to get the number of days before the warehouse is at max capacity
42,000 / 3000 = 14 days
Therefore, it will take 14 days for the warehouse to be filled
There were 8 fewer boys than girls in Mr. Taylor’s Algebra class. If he had 40 pupils, how many were girls?
Answer:
There are 24 girls in the class.
Step-by-step explanation:
Write out the problem like this:
40 = (g-8)+(g)
40 is the total amount of students. (g) is the unknown number of girls in the class, and (g-8) is the amount of boys since there are 8 fewer boys than girls.
First, eliminate the parentheses.
40 = g - 8 + g
Next, combine like terms. Both g's are positive, to we get 2g
40 = g - 8 + g
40 = 2g - 8
Then, add 8 to both sides of the equation, because the 8 that was already present is negative and needs to be canceled out.
40 + 8 = 2g - 8 + 8
48 = 2g
Lastly, divide both sides by 2, so that the (g) is by itself.
40/2 = 24, 2g/2 = g
g=24
This can be tested as the correct answer by subtracting 8 from 24 to count the boys...
24 - 8 = 16
...and adding the two amounts together to get the total amount of students.
24 + 16 = 40
There are 24 girls in the class.

use the circle to answer the questions
Answer:
Diameter: 10.8 cm
Circumference (in terms of π): 10.8π cm
Circumference (approximate): 33.91 cm
Step-by-step explanation:
Hi there!
We're given:
The radius (5.4 cm)1) Determine the diameter
[tex]d=2r[/tex]
Multiply the radius 5.4 cm by 2
5.4 × 2 = 10.8
Therefore, the diameter of the circle is 10.8 cm.
2) Determine the circumference of the circle
[tex]C=\pi d[/tex]
Plug in the diameter 10.8
[tex]C=10.8\pi[/tex]
Therefore, the circumference of the circle in terms of π is 10.8π cm.
3) Determine the approximate circumference of the circle
[tex]C=10.8\pi\\C=10.8(3.14)\\C=33.91[/tex]
Therefore, the approximate circumference of the circle is 33.91 cm.

it takes 2 1/2 cups of sugar to make 4 dozen sugar cookies. How much sugar is needed to make 120 sugar cookies
Answer:
6.25 cups of sugar
Step-by-step explanation:
Let's make a proportion expression:
2.5/48 = x/120
Let x be the amount of sugar needed to make 120 sugar cookies.
Cross multiply:
120*2.5=48x
48x=300
x=6.25
So, you would need 6 1/4 cups or 6.25 cups of sugar to make 120 sugar cookies.

Yes
Step-by-step explanation:
Try it.
Answer: 1st: No, 2nd: No, 3rd: Yes, 4th: Yes
Step-by-step explanation: You only flip the inequality when you divide a negative number on both sides. The only reason why you would divide would be to get the variable by itself - in this case the coefficient would need to be negative. That only applies to the third and 4th equations.
what is the degree of polynomial x^2y^2+y^3+4?
Answer:
The degree of the polynomial ≈ 4
Step-by-step explanation:
The degree of a polynomial, is given by the highest value of the sum of the exponents (powers) of the of the variables (monomials) that are present in the polynomial expression
The given polynomial expression is x²·y² + y³ + 4
The sum of the exponents; 2 + 2 = 4, and 3
The sum of exponents 4 > 3
Therefore, the degree of the polynomial = 4.
Yesterday, 37% of the drivers for Quinn's Taxi Service worked. At Bella's Taxi Express, 3 out of 10 drivers worked. Which taxi service had a greater percentage of its drivers working?
Answer:
Quinn's Taxi Service
Step-by-step explanation:
a) Yesterday, 37% of the drivers for Quinn's Taxi Service worked.
Hence, the percentage for Quinn's Taxi Service drivers that are working is 37%
b) At Bella's Taxi Express, 3 out of 10 drivers worked.
The percentage for Bella's Taxi drivers that are working is calculated as:
3/10 × 100
= 30%
Therefore, the taxi service that had a greater percentage of its drivers working is Quinn's Taxi Service with a high percentage of 37%

The triangles shown below are similar. Find the length of QS.
Answer: The value of QS is 8 cm.
Step-by-step explanation:
First calculating the side QT.
As per given figure:
ΔPQT ≈ ΔRST
[tex]\frac{PQ}{RS}=\frac{QT}{ST}[/tex]
Given:
PQ = 9 cm
RS = 3 cm
ST = 4 cm
Now putting all the given values in the above expression, we get:
[tex]\frac{PQ}{RS}=\frac{QT}{ST}\\\\\frac{9cm}{3cm}=\frac{QT}{4cm}\\\\QT=12cm[/tex]
Now calculating the value of QS.
QT = QS + ST
12 cm = QS + 4 cm
QS = 12 cm - 4 cm
QS = 8 cm
Thus, the value of QS is 8 cm.

Abigail buys two cartons of strawberries. One carton has 19 berries and the other carton has 26 berries. She wants to divide the berries into bags so there are exactly 6 berries in each bag. How many bags will have 6 berries?
Answer:
7.5 bag
Step-by-step explanation:
Carton #1: 19 berries
Carton #2: 26 berries
^^add them up together to get hte total amount of berries! 19 + 26 = 45
She has 45 berries in total, then you divid it by 6 aka the amount of berries she wants in each bag 45 ÷ 6 = 7.5
When she divids them up she has 7 bags with 6 berries in each and 1 bag with 3 berries.

Find the volume of the cylinder.
Either enter an exact answer in terms of π or use 3.143.t, 14 for π.
Answer:
V = 75 pi
Step-by-step explanation:
We know the volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi ( 5)^2 (3)
V = pi (25)(3)
V = 75 pi
===============================================
Work Shown:
r = 5 is the radius
h = 3 is the height
V = pi*r^2*h .... volume of a cylinder
V = pi*5^2*3
V = pi*25*3
V = pi*75
V = 75pi ..... exact volume in terms of pi
V = 75*3.14
V = 235.5
If you used the approximation pi = 3.14, then the approximate volume is about 235.5 cubic units. Use more decimal digits of pi to get a more accurate answer.
Note how the pi*r^2 portion represents the area of the circular base. So we can say
volume = (area of base)*(height)
