Answer:
29 is 6x^2+12+42
31 is 12x^5 -15x^3 = 30x^2
Step-by-step explanation:
cant do the rest sorry
Answer:
29.) 6x² + 12x + 42
30.) 4x - 4x²
30.) -x³ - 5x²
31.) [tex]12x^5-15x^3+30x^2[/tex]
32.) -3x³ + 6x² - 36x
Step-by-step explanation:
29. 6 ( x² + 2x + 7 )
* distribute the 6 to what's inside of the parenthesis *
6 * x² = 6x²
6 * 2x = 12x
6 * 7 = 42
6x² + 12x + 42
30. 4x ( 1 - x )
* distribute the 4x to what's inside of the parenthesis *
4x * 1 = 4x
4x * -x = -4x²
4x - 4x²
For some reason there is two number 30's
-x² ( x + 5 )
* distribute the -x² to what's inside of the parenthesis *
-x² * x = -x³
-x² * 5 = -5x²
-x³ - 5x²
31.) 3x² ( 4x³ - 5x + 10 )
* distribute the 3x² to what's inside of the parenthesis *
[tex]3x^2*4x^3=12x^5\\3x^2*-5x=-15x^3\\3x^2*10=30x^2\\12x^5-15x^3+30x^2[/tex]
32.) 3x ( -x² +2x - 12 )
* distribute the 3x to what's inside of the parenthesis *
3x * -x² = -3x³
3x * 2x = 6x²
3x * -12 = -36x
-3x³ + 6x² - 36x
Note: When multiplying variables with constants and exponents you add the exponents and multiply the constants
Ex. 3x² * 4x²
Multiply the constants ( 3 and 4 )
3 * 4 = 12
Add the exponents [tex]^2^+^2^=^4[/tex]
[tex]3x^2*4x^2=12x^4[/tex]
You have a set of 10 cards numbered 1 to 10. You choose a card at random. Event A is
choosing a number less than 8. Event B is choosing an even number. Calculate the
probability of A NB.
P(A NB) =
Answer:
35% or 35/100
Step-by-step explanation:
Gage Millar, Algebra 2 tutor
Choosing a number LESS than (not equal to 8) is 7/10 (1,2,3,4,5,6,7)
Chosing an even number is 5/10 (2,4,6,8,10)
so just multiply 7/10 x 5/10 to get 35 over 100, or a 35% chance

surface area of cube =6a²6×10²6×100600cm²stay safe healthy and happy.Five numbers have a range of 14. Four of the numbers are 20, 22, 31 and 25. Work out the two different possible values for the fifth number.
Answer:
17
34
Step-by-step explanation:
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
the missing number can either by the highest value or the lowest value. this is because none of the numbers given when subtracted from each other would give a value of 14
let x = missing number
14 = x - 20
x = 20 + 14 = 34
or
14 = 31 - x
x = 31 - 14
x = 17
gary has 20 pairs of socks in his drawer and 6 of those pairs are black 4 are yellow and 10 are white. what is the probability that if picks out of the drawer at random that they are not yellow
Answer:
The chance of not getting a yellow pair is 80% or 8/10
Answer:
4/5
Step-by-step explanation:
Probability: (ways to get a desired result) / (total possibilities)
There are 16 non-yellow socks and 20 socks.
Thus, the probability of not picking a yellow sock is:
16/20 = 4/5
In AABC, m2A = 87° and m2 B= 23°.
Select the triangle that is similar to AABC.
A. APQR, in which m2p=110° and
mZR= 23°
O B. ASTU, in which m2 S = 87° and
mzU= 70°
O C. ALMN, in which mZM = 20° and
m2N= 87°
O D. AXYZ, in which m2 X = 87° and
m2 Z= 50°
The triangle similar to ΔABC is ΔSTU, in which m∠S = 87° and m∠U = 70°. Option C
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
In ΔABC, we know that m∠A = 87° and m∠B = 23°.
The angle m∠C must therefore be 70°,
since the sum of the angles in a triangle is always 180°.
now, we have,
In ΔSTU, we are given that m∠S = 87°, which corresponds to ∠A in ΔABC.
We are also given that m∠U = 70°, which corresponds to ∠C in ΔABC.
so, we get,
as, This is because two triangles are similar if their corresponding angles are congruent.
Therefore, ΔSTU is similar to ΔABC.
The above answer is in response to the full question below
In Δ ABC, m∠A = 87° and m∠B = 23°.
Select the triangle that is similar to ΔABC.
A. ΔXYZ, in which m∠X= 87° and m∠z = 50°

Answer:
3x*59x=
Step-by-step explanation:
Answer:
126 degrees
Step-by-step explanation:
The opposite angles of a parallelogram are equal, so 4x + 2 = 8x - 50. By subtracting 4x from both sides of this equation, we get that 2 = 4x - 50. Adding 50 to both sides yields 52 = 4x, and dividing by 4 gives us that x = 13.
By substituting this, we see that the measure of angle A is 4(13)+2, which is 54 degrees. Angle B is supplementary to angle A, so its measure is 180-54, which is 126 degrees.

please help. i have no clue how to do this please give any tips :)
Answer: 36.25°
Step-by-step explanation:
Use SOHCAHTOA (sin, cosine and tangent)
SOHCAHTOA:
SOH: Sin(θ) = Opposite / Hypotenuse
CAH: Cos(θ) = Adjacent / Hypotenuse
TOA: Tan(θ) = Opposite / Adjacent
When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.
And just as a note, θ this symbol is called theta, and it represents an angle.
TAN(θ) = Opposite / Adjacent = 11/15
Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.
TAN(θ) = [tex]\frac{11}{15}[/tex]
θ = [tex]tan^-1(\frac{11}{15} )[/tex]
Then, using a calculator, solve. The answer is about 36.25°
Melanie brought 9 gallons of pink
lemonade to the school picnic, and
Shelby brought 16 quarts of orangeade.
How many gallons did the two girls
bring to the school picnic?
Answer: 25 Gallons
Step-by-step explanation:
My answer is correct because, if were just finding out how much gallons did both the girls bring then we just have to add 9 plus 16. 9 plus 16 equals 25.

In a new scale drawing of the same room, the length of the room measures 4 inches. What is the scale of the new drawing?
Answer:
6 feet = 1 inch
Step-by-step explanation:
The actual length of the room = 24 feets
The new scaled lengtb of the room = 4 inches
The scale of a drawing = actual length / scaled or model length
Hence, scale used = 24 feet / 4 inch = 6 feet / 1 inch
The scale of the new drawing :
6 feet : 1 inch
6 feet length of actual room length is equivalent to 1 inch length on the drawing

Which way is the wind blowing in relation to the land and ocean?
Answer: Hope This Helps!
Step-by-step explanation:
This wind happens to be the sea breeze. The sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.
Answer:
When the air mass above the land becomes cooler than the air mass over water, the wind direction and convective cell currents reverse and the land breeze blows from land out to sea.

there are 3 red, 1 blue and 2 purple marbles in a bag. once a marble is selected, it is replaced. what is the probability of picking a purple and blue? P (purple and blue)
Answer:
here
Step-by-step explanation:
There are total (3 purple + 4 orange + 1 green) = 8 marbles in the bag . Now, 2 marbles out of 8 marbles can be selected in C(8,2) = 8!/2!6! = 28 no. of ways . And 2 purple marbles out of 3 purple marbles can be selected in C(3, 2)
= 3!/2! 1! = 3 no. of ways. Hence the required probability = 3/28
Answer:
1/15
Step-by-step explanation:
3 red, 1 blue, 2 purple
P of purple and blue is the
P of purple * P blue =
(2purple/(3+1+2) )* (1blue/ (3+1+2-1)) = (2/6) * (1/5) = 2/30 = 1/15

No links/downloads. Please help me with my math homework
Answer:
Step-by-step explanation:
Let's baby-step this to make it easy, ok? Begin by getting rid of all the fractions, which means we will eliminate the 3 from the 1/3 by multiplying both sides be 3:
[tex]3V=\pi r^2 h[/tex]
If we want to eventually isolate the r, we need to move the h and the pi. Do this by division, since each of these is multiplied by r-squared. Doing that gives us:
[tex]\frac{3V}{\pi h}=r^2[/tex]
Lastly, to undo a square, we have to take the square root. We will do that for both sides of the equals sign:
[tex]+\sqrt{\frac{3V}{\pi h} }=r[/tex]
The positive is out front there to indicate that we don't want the negative value since distance is a measure that will never be negative.
