The midpoint of AB is M (-2,0) . If the coordinates of A are (1,-7), what are the coordinates of B
Answer:
Step-by-step explanation:
Hope this helps u!!
Answer:
B (- 5, 7 )
Step-by-step explanation:
Using the midpoint formula, then equate x and y coordinates
let coordinates of B = (x, y ) , then
[tex]\frac{x+1}{2}[/tex] = - 2 ( multiply both sides by 2 )
x + 1 = - 4 ( subtract 1 from both sides )
x = - 5
[tex]\frac{y-7}{2}[/tex] = 0
y - 7 = 0 ( add 7 to both sides )
y = 7
Coordinates of B = (- 5, 7 )
A two-factor between-subjects design is evaluated. The F-value for Factor A has df = 1, 40 and the F-value for Factor B has df = 3, 40. Based on this information, what are the df values for the A x B interaction?
Answer:
The df values for the A x B interaction are also 3,40
Step-by-step explanation:
The F-value for Factor A has df = 1, 40
The F-value for Factor B has df = 3, 40.
The df values for the A x B interaction are also 3,40
This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and the source of variation between rows has (r-1); rc(n-1) degrees of freedom and the source of variation of interaction
(between rows and columns) has ( c-1) ( r-1); rc(n-1) degrees of freedom.
Therefore
Factor A: ( c- 1); rc(n-1) = 1,40
Factor B: (r-1); rc(n-1) = 3,40
Interaction : ( c-1) ( r-1); rc(n-1) = 3*1,(40)= 3,40
where c refers to columns , r refers to rows and n refers to the total sample size.
Find the 6th term of the geometric sequence represented below. 3. 1, 0.5, 0.25, ...
Answer: Hi I Can not seem to calculate the answer but I can give you a way to find 6th term or the geomatric sequence.
By substituting the values for a, r and n we can find the desired term that we want. r=7525, cancelling out the common factors, we get r=3. As we want the 6th term to find, substituting n=6,r=3&a=25 in the above equation, we get (25)(3)6−1. Simplifying this expression, we get 6075.
Step-by-step explanation:
If I can find the calculations correctly i will redo this answer! Have a nice day!

Jenny and Kath hire the canal boat for 14 days. They share the hire cost of £1785.00 in the ratio 2:3. Work out the smaller share.
Answer:
£714.00
Step-by-step explanation:
The first step is to set up expresssions for the two shares:
Let x = the amount of one share. The other share is 1785 - x. You don't have to worry about which is smaller--that part will work out automatically!
The two shares are in the ratio of 2:3, so set up the proportion
[tex]\frac{x}{1785-x}=\frac{2}{3}[/tex]
Again, you don't have to worry--you could set up the proportion "upside down" and everything will work out in the end.
Solve the proportion for x by "cross multiplying" -- use the Means-Extremes Property of proportions.
[tex](3)(x)=(2)(1785-x)\\3x=3570-2x\\5x=3570\\x=714[/tex]
So one share is £714£ and the other is £1785 - £714 = £1071.
The smaller share is £714.

Answer:
100 cm²
Step-by-step explanation:
Given that :
Length of prism = 20 cm
Height, h = 5cm
Width, w = 4 cm
The surface are of the side with clear material can be obtained by calculating the area of rectangule (front)
Area of rectangle = Length * height

y=50 but i dont know x, sorry about that its cause im in class rn lol
Answer:
x= 127
y = 50
Step-by-step explanation:
y = 180 -130(angles on a straight line)
y= 50
x= 360-(123+60+50). angles in a quadrilateral
x = 360- 233

Which of the following statements is false
Answer: C IS THE ANSWER
Step-by-step explanation:
express 450 g as a percentage of 20 kg
Answer:
Step-by-step explanation:
convert either gram into kg or kg into gram
lets convert kg into g
1 kg=1000g
20kg=1000*24g
=20000g
450/20000*100%
450/200%
2.25%
first convert 450 g to kg = 0.45 kg
Now 0.45 kg as a. percentage of 20 kg = 0.45/20×100= 2.25%

Tulsa has 4 times as many mangoes as Julie. Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie . How many many mangoes Tulsa had at first
Answer:
24
Step-by-step explanation:
Let the number of mangoes owned by Tulsa be T and that by Julie be J
If Tulsa has 4 times as many mangoes as Julie then
T = 4J
Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie
T + 6 = 5J
Solve both equations simultaneously by substitution
4J + 6 = 5J
Collect like terms
6 = 5J- 4J
J = 6
Since
T = 4J
T = 4 * 6
= 24
Hence Tulsa had 24 mangoes at first

Sum of 2 fifths of x and 6x and 6 in algebraic expression
Sum of 2 fifths of x and 6x and 6 in algebraic expression = 2/5 x +6x +6
Answer:
(14x+12)/5
Step-by-step explanation:
2 fifth of x = 2/5 * x= 2x/5
2 fifth of 6x = 2/5 * 6x = 12x/5
2 fifth of 6 = 2/5 * 6 = 12/5
2x/5 + 12x/5 + 12/5
= (2x+12x+12)/5
= (14x+12)/5

What is the surface area of a conical grain storage tank that has a height of 54 meters and a diameter of 18 meters round the answer to the nearest square meter
Answer:
1803 square meter
Step-by-step explanation:
The surface area of a cone
A=πr(r+V(h2+r2))
where A is the surface area, r is the radius and h is the height
Given that the height of 54 meters and a diameter of 18 meters, the radius is half the diameter hence
radius = 18/2 = 9 m
A = 9π (9 + V(54^2 + 9^2))
= 9π (9 + V2997)
= 9π (9 + 54.74486)
= 1803.068976 Square meters
To the nearest square meter
A = 1803

6 mi 8 mi What is the length of the hypotenuse? miles
Answer:
10 miles
Step-by-step explanation:
6² + 8² = x²
36 + 64 = x
36 + 64 = 100
√100 = 10
Answer:
6) 1/2 + 1/2 + 1/2 + 1/2 = 4/2 = 2 inches.
7) 5/8 + 5/8 + 5/8 = 15/8 = 1 7/8 inches.
8) We've added the 1/2-inch crystals together and the 5/8-inch crystals together. Adding together the 3/4-inch crystals we have:
3/4 + 3/4 + 3/4 = 9/4 = 2 1/4 inches
Adding together the 3/8-inch crystals we have:
3/8 + 3/8 + 3/8 = 9/8 = 1 1/8 inches.
Totaling what we have:
2 + 1 7/8 + 2 1/4 + 1 1/8
= 2 + 1 7/8 + 2 2/8 + 1 1/8 (you can only add fractions if they have common denominators)
= 6 + 7/8 + 2/8 + 1/8 (add the whole numbers together)
= 6 10/8 = 6 + 1 2/8 = 7 2/8 = 7 1/4 inches.
9) To find an average, we add all of the data points together and divide by the number of data points. We added them in number 8. Now we divide this total, 7 1/4, by 13:
7 1/4 ÷ 13 = 29/4 ÷ 13/1 = 29/4 × 1/13 = 29/52 inches average for the crystals.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
