Answer:
45 degrees
Step-by-step explanation:
Think of this web as a circle. This circle is divided into 8 equal pieces.
A circle has 360 degrees in it. If we divide 360 by 8, we get 45. This means that each wedge is 45 degrees, which means that in order to rotate the image to look the same, we must rotate it by 45 degrees.

Answer:
x = -5/3 and y = -1
Step-by-step explanation:
write it as a system and simplify
-4 for the first equation (in the photo but when putting it into a system of equations it would be 2nd)
So it's
-3x-2y=7
-3x+2y=3
then it's -6x=10
then divide oth sides by -6 to get x then plug that into whatever equation and solve for y.
i hope this is right and helps

solve for x
-3 + 8x - 5 = -8
Answer:
x=0
Step-by-step explanation:
combine like terms
-8+8x=-8
add 8 to both sides
8x=0
x=0
The solution is 0
Answer:
x = 0
Step-by-step explanation:
When we combine like terms on the left side we get -8 + 8x = -8. Adding 8 to both sides to get rid of the -8 we get 8x = 0, and dividing the whole equation by 8 to get rid of the coefficient of x we get x = 0.

PLZZZZ HELP MEEEE!!!! (30 points)
Answer:
Step-by-step explanation:
Slope is the rise (y) over the run (x) between 2 points on a graph. This means that from one point go up (or down) first, then count over from that first point right (or left). A positive number on top indicates "up" and a negative number on top indicates "down"; a positive number on bottom indicates "right" while a negative number on bottom indicates "left". Keep in mind the following:
[tex]\frac{-y}{x} =\frac{y}{-x} =-\frac{y}{x}[/tex]
It doesn't matter where you "put" the negative, your slope will come out correct as long as you are moving from one point to the other correctly.
Our given slope is 4/5. They are both positive, so that means from the red point on the left ("read" a graph from left to right, just like you're reading this) we will go up 4 units. From where we "land" we will go right 5 units. As you can see, the only graph that lands on the red dot on the right when we follow that slope is the second one.

Answer:
157.98 [tex]in^2[/tex]
Step-by-step explanation:
Given: volume of pyramid is equal to 100 cubic inches and height of the pyramid is 5 inches
To find: surface area of the pyramid
Solution:
Let h denotes the height of the pyramid and 'a' denotes side of the square base of the pyramid.
Volume of the pyramid = [tex]\frac{1}{3}a^2h[/tex]
Also,
Volume of the pyramid = 100 cubic inches
[tex]\frac{1}{3}a^2h=100\\\frac{1}{3}a^2(5)=100\\a^2=\frac{100\times 3}{5}=60\\a=\sqrt{60}[/tex]
Surface area of the pyramid [tex](S) =a\sqrt{4h^2+a^2}+a^2[/tex]
So,
[tex]S=\sqrt{60}\sqrt{100+60}+60\\=\sqrt{60}\sqrt{160}+60\\=\sqrt{9600}+60\\=97.9796+60\\=157.9796\\\approx 157.98[/tex]
Surface area = 157.98 [tex]in^2[/tex]
Answer:
Surface area of the pyramid = 157.99 in²
Step-by-step explanation:
Volume of a pyramid is given by the formula,
Volume = [tex]\frac{1}{3}(\text{Area of the base})\times \text{height}[/tex]
100 = [tex]\frac{1}{3}\text{(Side)}^{2} \times \text{height}[/tex]
300 = s² × 5
s² = 60
s = √60
s = 2√15 in ≈ 7.746 in
Now surface area of the pyramid = Area of base + 4×(Area of one lateral side)
Area of square base = (Side)² = 60 in
Area of one lateral side = [tex]\frac{1}{2}(\text{Base})(\text{Lateral height})[/tex]
Since Lateral height = [tex]\sqrt{(h)^{2}+(\frac{S}{2})^{2}}[/tex] [By applying Pythagoras theorem in the given triangle]
= [tex]\sqrt{(5)^{2}+(3.873)^{2}}[/tex]
= [tex]\sqrt{25+15}[/tex]
= [tex]\sqrt{40}[/tex]
= 6.325 in.
Now area of lateral side = [tex]\frac{1}{2}(7.746)(6.325)[/tex]
= 24.497 in²
Surface area of the pyramid = 60 + (4×24.497)
= 60 + 97.987
= 157.987 in²
≈ 157.99 in²
Please answer the 16th qs
Answer:
p = 13
Step-by-step explanation:
When a polynomial f(x) is divided by (x + h) then the remainder is f(- h)
Here both polynomials are divided by (x + 1)
Evaluate them both for x = - 1
3(- 1)³ - 5(- 1)² - 4(- 1) + p, that is
- 3 - 5 + 4 + p
= p - 4 → A
6(- 1)³ + p(- 1)² + 9(- 1) + 5, that is
- 6 + p - 9 + 5
= p - 10 → B
Given that A = 3B, then
p - 4 = 3(p - 10)
p - 4 = 3p - 30 ( subtract 3p from both sides )
- 2p - 4 = - 30 ( add 4 to both sides )
- 2p = - 26 ( divide both sides by - 2 )
p = 13
Imagine that you are given two linear equations in slope-intercept form. You

many solutions would you expect for this system of equations?
A.0
B.cannot be determined
C.1
D.infinitely many

y= mx+b
with same slope, m= same for both
if b is different, then the lines are parallel

According to a survey done at your school, about 42% of all the female students participate in 2 sport seasons. You randomly ask 5 female students at your school how many sport seasons they participate in. What is the probability that at least 3 of the 5 female students surveyed participate in 2 sport seasons? Show your work.
Answer: 0.353
Step-by-step explanation:
We know that 42% of all the female students participate in 2 sports this season. (58% is the percent that did not)
This means that if we select a random student, there is a 0.42 probability that the student did participate in 2 sports this season.
Other thing that i will use is that, if we have a group of N objects, and we want to create a group of K objects out of the N, the number of combinations is:
[tex]c = \frac{N!}{(N - K)!*K!}[/tex]
Now, out of 5, we want to find the proability that, at least 3 of them, did participate in at least 2 sports this season.
The probability that all 5 of them participated, is equal to the product of the individual probabilities. (so N = 5, and K = 5)
P = (0.42^5)*1 = 0.013
Now, if only 4 of them did participate (N = 5, k = 4), the probability is equal to:
P = (0.42^4)*(0.58)*5!/4! = (0.42^4)*(0.58)*5 = 0.09
The probability for only 3 is: (N = 5 and K = 3)
P = (0.42^3)*(0.58^2)*5!/(3!*2!) = (0.42^3)*(0.58^2)*(5*4/2) = 0.25
Then the total probability is:
P = 0.013 + 0.09 + 0.25 = 0.353

The sample loses 1/3of it’s mass every ___ days
Answer:
The sample loses [tex]\frac{1}{3}[/tex] of its mass every [tex]\frac{1}{3}[/tex] days.
Step-by-step explanation:
Expression that shows the relation between final mass of the element after 't' days is,
M(t) = [tex]900(\frac{8}{27})^t[/tex]
If M(t) = two third of the initial mass [After the loss of one third of the initial mass remaining mass of the element = 1 - [tex]\frac{1}{3}[/tex] = [tex]\frac{2}{3}[/tex]rd of the initial mass]
[tex]900\times \frac{2}{3}=900(\frac{8}{27})^t[/tex]
[tex]\frac{2}{3}=(\frac{8}{27})^t[/tex]
[tex]\frac{2}{3}=[(\frac{2}{3})^3]^t[/tex]
[tex](\frac{2}{3})^1=(\frac{2}{3})^{3t}[/tex]
By comparing powers on both the sides
3t = 1
t = [tex]\frac{1}{3}[/tex] day
Therefore, The sample loses [tex]\frac{1}{3}[/tex] of its mass every [tex]\frac{1}{3}[/tex] days.

Consider this scaled figure of a swimming pool. The dimensions of the original pool are 24 feet wide by 36 feet long. A rectangle has a width of 6.4 feet and a width of question mark feet. Use the measurements of the original and of the scaled figure to find the scale factor and the missing length. What is the scale factor? What is the missing length of the scale model?
Answer:
Scale Factor- 4/15
Missing length- 9.6
Step-by-step explanation: Got it right on Edge.
The missing length of the rectangle B is 9.6 feet and the proportion is 3.75
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the area of the rectangle 1 be represented as A = 24 x 36
where the width = 24 feet and length = 36 feet
Now , the area of the second rectangle 2 = 6.4 x y
The width = 6.4 feet
So , the scale factor is given by the proportion equation ,
k = 24 / 6.4 = 3.75
So , the scale factor k = 3.75
Now , the length of the second rectangle = 36 / 3.75 = 9.6 feet
Hence , the proportion is k = 3.75

Hiking on the map, AB represents a trail that you are hiking. You start from the beginning of the trail and hike for 90 minutes at a rate of 1.4 mph how much farther do you need to hike to reach the end of the trail
Answer:
Distance remaining = 3.1 miles
Step-by-step explanation:
Distance between A(3, 2) and B(8.2, 2) can be calculated by the formula,
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
AB = [tex]\sqrt{(8.2-3)^2+(2-2)^2}[/tex]
= 5.2 mi
Since you have hiked for "90 minutes or 1.5 hours" at the rate of 1.4 mph,
From the formula,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
1.4 = [tex]\frac{\text{Distance}}{1.5}[/tex]
Distance traveled = 1.4 × 1.5
= 2.1 miles
Distance remaining to travel = 5.2 - 2.1
= 3.1 miles
Therefore, distance remaining to travel = 3.1 miles
