I like dogs but this question is a hard one.
Answer:
Work below
Step-by-step explanation:
49 total dogs.
36 more small dogs.
13 big dogs.
lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.
the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.
Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.
F** k today's hw and their wording
Answer:
6.5 Large Dogs
42.5 Small Dogs
Step-by-step explanation:
You simply do not have enough love for dogs to solve the question.
Luckily I have an extremely high affection for dogs so I can help.
S = amount of small dogs
L = amount of large dogs
S + L = 49
S = 36 + L
plug the second equation into the correct variable of the first equation so:
(36+L) + L = 49
36 +2L = 49
2L = 49-36
L = 6.5 *this doesn't make sense*
S = 42.5 *this also doesn't make sense*
I don't know why your questions produce answers with 6 and a half dogs, haha, but these are the correct answers. Math never lies!
Rui is a professional deep water free diver. His altitude (in meters relative to sea level), xxx seconds after diving, is modeled by: d(x)=\dfrac12x^2 -10xd(x)= 2 1 x 2 −10xd, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided by, 2, end fraction, x, squared, minus, 10, x How many seconds after diving will Rui reach his lowest altitude?
Answer:
Rui will reach his lowest altitude after 20seconds of diving
Step-by-step explanation:
Given the function that models the altitude of Rui at any time x expressed as:
d(x) = 1/2 x² - 10x
The height of rui at his lowest altitude will be zero. Substitute d(x) = 0 into the expression and get x
d(x) = 1/2 x² - 10x
0 = 1/2 x² - 10x
-1/2x² = 10x
1/2 x = 10
Multiply both sides by 2
x/2 × 2 = 10×2
x×1 =20
x = 20
Hence Rui will reach his lowest altitude after 20seconds of diving

Step-by-step explanation:
There are a few ways you can go at this. Perhaps the simplest is to recognize that 81 is a power of 3.
log₃(81) = log₃(3⁴)
log₃(81) = 4

You can also use the "change of base" formula:
log₃(81) = log(81)/log(3) ≈ 1.908485/0.4771213

Answer:
An example of complementary angles would be Angle FA and Angle EF
Step-by-step explanation:
These angles add up to 90 degrees
Hope this helps!
Answer:
∠AGF and ∠FGE, or ∠BGC and ∠CGD
Explanation
complementary angles are any angles which add up to 90°. since ∠AGB is a right angle according to the diagram, and AGD as well as BGE are straight lines (assumption), ∠DGE is also equivalent to 90° (opposite angles).
thus, the sum of ∠AGE and ∠BGD would be 90° each, so we know that ∠AGF and ∠FGE or ∠BGC and ∠CGD each add up to 90°.

build the graph of the equation (x+2)(y-5)=0
Answer:
Step-by-step explanation:
Set each factor equal to zero and solve for the indicated variable.
x + 2 = 0 yields x = -2, or (-2, 0). Plot this (-2, 0). (This is the x-intercept.)
y - 5 = 0 yields y = 5, or (0, 5). Plot this (0, 5) (This is the y-intercept.)
Finally, draw a line through these two intercepts.

Step-by-step explanation:
Please help. I’ll mark you brainliest. But no link andwers
Answer: y = -2x + 6
Slope-intercept form: y = mx + b, where m = slope and b = y-int
m = -2
(-1, 8) --> -1 = x₁, 8 = y₁
Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:
y - 8 = -2[x -(-1)]
y - 8 = -2(x + 1)
y - 8 = -2x - 2
y = -2x + 6

If we buy 20 pickles, what is the experimental probability of winning 5 or more tickets?
Answer:
66%
Step-by-step explanation:
The experimental probability of winning 5 or more tickets is 90%
How to determine the probability?To do this, we simply add the probability values of the bars that have a value of 5 or more
So, we have:
P(x >= 5) = (5 + 8 +17 + 19 + 20 + 21)%
Evaluate the sum
P(x >= 5) = 90%
Hence, the experimental probability of winning 5 or more tickets is 90%

The sun causes changes to things on Earth. Think of an object you have observed before and after it was left out in the sun. Describe how it changed.
Answer: well i have put things like leather and it shrunk while it was out in the sun
Step-by-step explanation:
We want to study how the Sun affects things on Earth, I will give you two examples.
First, we know that the Sun radiates electromagnetic energy.
So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.
The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).
Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.
So these are just two different examples of how the Sun affects things on Earth.

A regular polygon is a shape with sides that all have equal lengths and angles that all have equal measures. If each exterior angle of a certain regular polygon measures 24o, what is the interior angle sum for this polygon?
Answer:
2340
Step-by-step explanation:
360/24 =15whichis number of sides
180(15-2)=2340
Answer:
Exterior Angle of 24º means Interior Angle of 156º
Interior Angle = 180 -Exterior Angle
Number of sides = 360 / (180 - ONE Interior Angle)
Number of sides = 360 / (180 - 156º)
Number of sides = 360 / 24
Number of Sides = 15
