#CarryOnLearningThe midpoint of AB isM(2,5). If the coordinates of A are (−3,6), what are the coordinates of B?
Answer:
(7,4)
Step-by-step explanation:
Midpoint Formula = [tex](x_{1} + x_{2}/2)=[/tex] x coordinate of midpoint
same for y coordinate of midpoint
so
2=-3+x/2
4=-3+x
x=7
for y
5=6+y/2
10=6+y
y=4
therefore B(7,4)

Answer:
The formula is adding 8 for every row of seats.
Step-by-step explanation:
This is because the relationship between these numbers keep on adding 8 so for instance next row would have 84 seats.

(I’ll mark brainliest ) The cross country running team is hosting their first home race and needs to plan and set up the course. The only tool available to record the distance measures in feet. If the course must be at least 3 miles but no more than 3.2 miles in length, what is the smallest and the largest number of feet they must walk in order to fulfill the requirements?
1 mile 5,280 feet.
Smallest:
Largest:
Answer:
Smallest: 15,840 ft
Largest: 16,896 ft
Step-by-step explanation:
1 mi = 5,280 ft
Setup proportion to solve for the smallest:
[tex]\frac{1mi}{5,280ft} =\frac{3mi}{xft}[/tex]
Do butterfly method and you should get this:
[tex]xft=3(5280)\\x=15,840ft[/tex]
Setup proportion to solve for the largest:
[tex]\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}[/tex]
Butterfly method:
[tex]xft=3.2(5280)\\x=16,896ft[/tex]

Happy I can help
Answer:
48
Step-by-step explanation:
We are going to use trigonometry to solve for the wanted angle
Remember these are the trigonometric functions
( Remember SOH CAH TOA )
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
For angle Ф
we are given its adjacent side length (6) and the hypotenuse (9)
Adjacent and hypotenuse corresponds with the trig function Cosine
So we will use cosine to solve for the missing angle
( let x = missing angle )
( remember cosine = adjacent over hypotenuse )
[tex]cosX=\frac{6}{9} \\\frac{6}{9} =.66\\cos(x)=.66[/tex]
now we want to get rid of the "cos" on the x
To do so we take the inverse of cos ( arc cos ^-!1 ) and apply it to each side
so...
[tex]arcos(cos(x))=x\\arccos(.66)=48.1[/tex]
we're left with x = 48.1
Last year, Nicholas started babysitting to earn extra spending money. Over the summer, he tracked how much money he earned at each babysitting jobThis box plot shows the results What percent of the time did Nicholas earn $25 or less?
Answer:
25%
Step-by-step explanation:
The 5 values of the given box plot are;
The minimum value = 20
The first quartile, the 25th percentile point, Q₁ = 25
The median or second quartile, the 50th percentile point, Q₂ = 30
The third quartile, the 75th percentile point, Q₃ = 40
The maximum value = 55
The range = The maximum value - The minimum value
∴ The range = 55 - 20 = 35
We note that Nicholas earned $25 or less from the minimum value up to first quartile, Q₁, which is the 25th percentile point, where we have 25 percent of the data points
Therefore, the percent of the time Nicholas earned $25 or less is 25 percent of the time.

Find the value of two numbers if their sum is 19 and and their difference is 5
Answer:
7 and 12
Step-by-step explanation:
x - y = 5
y = (5+x)
x+ (5+x) = 19
2x +5 = 19
2x = 14
x = 7
19-7 = 12
12 +7 = 19
12-7 = 5

Note: Round your answer to the nearest tenth.
Given:
In a right angle triangle ABC, [tex]m\angle B=90^\circ, BC=x, AC=11, m\angle C=41^\circ[/tex].
To find:
The value of x to the nearest tenth.
Solution:
In a right angle triangle,
[tex]\cos\theta =\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right angle triangle ABC,
[tex]\cos \angle C =\dfrac{BC}{AC}[/tex]
[tex]\cos (41^\circ) =\dfrac{x}{11}[/tex]
[tex]11(0.7547) =x[/tex]

What type of seismic waves can travel through the center of the Earth and be picked up by a seismograph on the other side of the world?
Answer: primary waves
Step-by-step explanation: pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary". These waves can travel through any type of material, including fluids, and can travel nearly 1.7 times faster than the S-waves.

Cube numbers between 100 and 400
Answer with step-by-step explanation:
Let us find the perfect cubes between 1 to 100.
We know that, 1
3
=1,2
3
=8,3
3
=27,4
3
=64 and the rest numbers i.e. 4,5,6,.... have their cubes greater than 100.
So, only these four numbers have their cubes between 1 to 100.
Thus, there are 4 perfect cubes from 1 to 100.
Now, let's find the cubes between −100 to 0
We know, 0
3
=0,(−1)
3
=−1,(−2)
3
=−8,(−3)
3
=−27,(−4)
3
=−64 and the rest numbers have their cubes less than −100
So, only these 5 numbers have their cubes between −100 to 0 and 4 perfect cubes are there from 1 to 100.
Thus, there are 9 perfect cubes from −100 to 100.

1. A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and put back, and then another marble is drawn. What is the probability that a blue marble was drawn followed by a yellow marble?
2. A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and not put back, and then another marble is drawn. What is the probability that a blue marble was drawn followed by a yellow marble?
Thank you.
Answer:
1. 0.0469 (4.d.p)
2. 0.05
Step-by-step explanation:
1. First we'll find the probability of drawing a blue marble.
P = (No. favourable events)/(Total events)
In this case it's:
P = (No. blue marbles)/(Total Marbles)
Therefore P(Blue) = 4/16 = 0.25
Now we find the probability of drawing a yellow marble:
The total number will be the same because the blue marble will have been put back.
P(Yellow) = 3/16 = 0.1875
Now, since we are calculating the probability of both happening we multiply together the two individual probabilities to get the combined probability of both:
0.25 x 0.1875 = 0.0469 (4.d.p)
2. The probability of drawing a blue marble is still the same so we can keep that: P(Blue) = 0.25
But this time, the marble is not replaced. This means that the total number of marbles has changed when drawing the yellow marble:
P(Yellow) = 3/15 = 0.2
Now we multiply them together again to find the combined probability of both happening:
0.25 x 0.2 = 0.05
Hope this helped!

Which of the following expressions is not equal to 64?
A. 2^4 . 2^-3 .2^4 .2
B. 2^2 .2^8 .2^-4 .2^0
C.2^0 .2 . 2^2 .2^3
D. 2^6 . 2^-3 . 2^4 . 2
Answer:
A. 2^4 . 2^-3 . 2^4 . 2
Step-by-step explanation:
Option A,
2^4 . 2^-3 . 2^4 . 2
= 2^4 . 2^-3 . 2^4 . 2^1
= 2^( 4 + 4 + 1 - 3 )
= 2^( 9 - 3 )
= 2^6
= 64
So, Option A is the correct answer.
Which expression is equivalent to -8 - (-12)
8 - 12
-8 + 12
-8 - 12
-8 (8+12)

If you place a 39-foot ladder against the top of a building and the bottom of the
ladder is 33 feet from the bottom of the building, how tall is the building? Round to
the nearest tenth of a foot.
The ladder and the top of the building form a right triangle
The building is 20.8 feet tall
`How to determine the height of the building?The given parameters are:
Length of ladder, L = 39 feetHorizontal distance (b) = 33 feetThe height (h) of the building is calculated using the following Pythagoras theorem
L^2 = b^2 + h^2
So, we have:
39^2 = 33^2 + h^2
Evaluate the exponent
1521 = 1089 + h^2
Rewrite as:
h^2 = 1521 - 1089
h^2 = 432
Take the square root of both sides
h = 20.8
Hence, the building is 20.8 feet tall
