find the square (3x+y)
Answer:
9x² + 6xy + y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 3x
b = y
(3x +y)² = (3x)² + 2*3x*y + y²
= 9x² + 6xy + y²
(3x)² = 3²*x² = 3*3*x² = 9x²
when measuring the radius of a sphere an error of 0.6% takes place in the measurement. What will be the permiable error while measuirng the surface
Answer:
So, the error is [tex]4.8\pi r[/tex].
Step-by-step explanation:
Error in measuring the radius = 0.6 %
Let the radius is r.
The surface area of sphere is
[tex]S= 4\pi r^2\\\\dS = 4 \pi\times 2 r dr\\\\dS =8\pi r \times 0.6 = 4.8\pi r[/tex]
Bonjour, je suis en 4e et j’aimerais que vous m’aidiez avec cette feuille d’exercice s’il vous plaît ? (en précisent vos réponses).
Merci d’avance.
Step-by-step explanation:
1. Soit
T = le coût d'un ticket
5T + 1.8 = 35
T = (35-1.8)/5 = 6.64
On ne sait pas le coût d'un ticket de tramway! :(
2.
a.
1 h : 60 min
x : 18
x = 1*18/60 = 0.3, ou 0.3h
b. => 1h18m = 1.3h
3. 16 L : 4 h
a.
x L : 365*24
x = 365*24 * 16/4 = 35040 L
b.
1 m^3 = 1000 L : 5.2 euros
35040 L : y euros
y = 5.2*35040/1000 = 182.21 euros (au centième)
4.
a. Voir graphique ci-attachée.
b. On voit bien que tous les points tombent sur la droite passant par l'origine, donc la relation est linéaire, ou proportionnelle.
c. La hauteur requise pour 270L est de 100 cm, approximativement, selon la graphique.
Notez la ligne bleue horizontale.
d. L'équation de la capacité (C) versus la hauteur (h) est
C(h) = (8/3)h
Pour C=270, 270 = (8/3)h => h=270*(3/8) = 101.25

Express 1.2 km as a percentage of 300 m
Answer:
1.2km is 400% of 300m
Step-by-step explanation:
1 km=1000m
So,1.2 km=1000*1.2=1200m
Let 1.2km(or 1200m) be x% of 300 m
By the problem,
300*x/100 = 1200
Or, 3x=1200
Or,x=1200/3=400
1.2km is 400% of 300m
mark had 3/2 cans of paint and used 1/2 can for his room. what fraction of the paint did he use
Given:
Mark had [tex]\dfrac{3}{2}[/tex] cans of paint and used [tex]\dfrac{1}{2}[/tex] can for his room.
To find:
The fraction of the paint did he use.
Solution:
Total paint = [tex]\dfrac{3}{2}[/tex] cans
Paint used = [tex]\dfrac{1}{2}[/tex] can
The fraction of the paint did he use is:
[tex]\text{Required fraction}=\dfrac{\text{Paint used}}{\text{Total paint}}[/tex]
[tex]\text{Required fraction}=\dfrac{\dfrac{1}{2}}{\dfrac{3}{2}}[/tex]
[tex]\text{Required fraction}=\dfrac{1}{3}[/tex]
Therefore, Mark use [tex]\dfrac{1}{3}[/tex] of the paint.

According to the results for Patient 2 shown above, which antigens were present in Patient 2’s blood? Check all (if any) that apply. A antigen B antigen Rh antigen Patient 2 has Type ✔ AB– blood. Based on these results, which type(s) of blood can this patient safely receive? Check all that apply. A B AB O Also, the patient should receive blood that is for Rh.
Answer:
Blood is further classified as being either "Rh-positive" (meaning it has Rh factor) or "Rh-negative" (without Rh factor). So, there are eight possible blood types: O negative... blood type doesn't have A or B markers, and it doesn't have Rh factor
Blood type AB can also be applied

a glide reflection to move a table with legs from one side of the room to the other. Will a glide
reflection result in a functioning table? Explain.
9514 1404 393
Answer:
yes
Step-by-step explanation:
A table is a 3-D object. It makes no sense to talk about reflecting it across a point or line. If the table is reflected across a vertical plane, the top will remain "up" and the legs will remain "down".
A glide reflection across a vertical plane will result in a functioning table.

I have a large money box, about 10 inches wide and 5 inches tall. Roughly, how many coins can I place in my empty money box?"
Answer:
Overall, it depends what type of coin you are using because each ones size is different. Or, if you are referring to the riddle it will be just one coin.
The correct answer is approximately 3,968 coins can be placed in the empty money box based on estimation. Based on these calculations, you can roughly estimate a volume calculation that place around 7936 coins in your empty money box, assuming the coins are similar in size to a quarter.
To estimate the number of coins that can fit in your money box, we need to consider the volume of the box and the volume of a single coin.
Calculate the volume of the money box:
Volume = Length * Width * Height
Volume = 10 inches * 10 inches * 5 inches
Volume = 500 cubic inches
Estimate the volume of a single coin. Let's assume a common coin, such as a quarter:
Diameter of a quarter ≈ 0.96 inches
Thickness of a quarter ≈ 0.07 inches
Volume of a coin ≈ π * ([tex]radius^2[/tex]) * thickness
Volume of a quarter ≈[tex]3.14 * (0.48) ^2 * 0.07[/tex]inches
Volume of a quarter ≈ 0.063 cubic inches
Calculate the number of coins that can fit in the money box:
Number of coins ≈ Volume of the money box / Volume of a coin
Number of coins ≈ 500 cubic inches / 0.063 cubic inches
Number of coins ≈ 7936 coins (approximately)
Therefore, approximately 3,968 coins can be placed in the empty money box based on estimation. Based on these calculations, you can roughly estimate a volume calculation that place around 7936 coins in your empty money box, assuming the coins are similar in size to a quarter.

In a ABC shown below, side AC is extended to point D with m Z DAB= (180 – 3x) °, mZ B= (6x – 40) °, and m ZC = (x+20) °.
Whats the measure of angle BAC?
Answer:
60°
Step-by-step explanation:
Given :
DAB= (180 – 3x) °,
mZ B= (6x – 40) °, and
m ZC = (x+20) °.
DAB = mZ B + m ZC ( the exterior angle equal the sum of the two opposite interior angles)
180 - 3x = (6x - 40) + (x + 20)
180 - 3x = 6x - 40 + x + 20
180 - 3x = 6x + x - 40 + 20
180 - 3x = 7x - 20
180 + 20 = 7x + 3x
200 = 10x
x = 200/10
x = 20
Angle B = 6x - 40 = 6(20) - 40 = 120 - 40 = 80
Angle C = x + 20 = 20 + 20 = 40
BAC = 180 - (80 + 40) (SUM OF ANGLES IN A TRIANGLE)
BAC = 180 - 120
BAC = 60°
In ΔJKL, the measure of ∠L=90°, JL = 80, KJ = 89, and LK = 39. What is the value of the sine of ∠J to the nearest hundredth
Given:
In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.
To find:
The value of sine of ∠J.
Solution:
In a right angle triangle,
[tex]\sin\theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
In triangle JKL,
[tex]\sin J =\dfrac{LK}{KJ}[/tex]
[tex]\sin J =\dfrac{39}{89}[/tex]
[tex]\sin J =0.4382[/tex]
[tex]\sin J \approx 0.44[/tex]
Therefore, the value of sine of ∠J is about 0.44.
(easy math question please help) find the value of x question #5
Answer:
x = 10
Step-by-step explanation:
Angles in a triangle add up to 180°. Using this, we can form the following equation:
71° + 50° + 6x - 1 = 180. A simplified version is this: 120° + 6x = 180
Remove 120° from both sides to get:
6x = 60
Divide both sides to get:
x = 10
