HCF of the algebraic terms 3xy and 4x = x
Answer:
x
Step-by-step explanation:
HCF of the algebraic terms 3xy and 4x is x because x is common in both the terms.
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

Answer:
correct answer is d. 0.50 per pound
explanation-
equation of line is y=mx+c
where c is the point where the line intersects y axis. (0,0) in this case.
and m is the slope, which we need to find.
from the graph, when x=2, y=1. putting in above equation
1=2m+0
implies m=0.5
Answer:
$. 50 per pound
Step-by-step explanation:
We need to find the slope
We have two points (0,0) and (2,1.00)
m = (1-0)/(2-0)
=1/2
=.50
$. 50 per pound
In a right triangle, the sides that form the right angle are the legs; the longest side (opposite the right angle) is the hypotenuse. Some textbooks say that when two right triangles have congruent pairs of legs, the right triangles are congruent by the reason LL. In our work, LL is just a special case of one of the postulates in this section. Which postulate is that
Answer:
SAS postulate
Step-by-step explanation:
Given
LL postulate
Required
What type of postulate is LL
LL means 2 legs are equal.
When 2 legs of the right triangle are equal, then it means that two sides of the right triangle
In the actual sense, this postulate is SAS postulate where 2 sides are also equal.
Hence, the LL postulate is a special case of SAS

In 2010, the population of a city was 90,000. From 2010 to 2015, the population
grew by 8%. From 2015 to 2020, it fell by 6%. To the nearest 100 people, what was
the population in 2020?
Answer:
5800
Step-by-step explanation:
8% of 90,000 = 7,200
90,000 + 7,200 = 97,200
6% of 97,200 = 5832
Rounded to the nearest hundred: 5800

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
Hope it helps...
Answer:
AB-
Step-by-step explanation:
Solve for A if Ab = ut
Solve for c if Kc = 9 a
Solve for D if Bd = Ca
Answer:
Below in bold.
Step-by-step explanation:
Ab = ut
Divide both sides by b
A = ut/b.
The other 2 are solved in a similar way:
Kc = 9a
c = 9a/K
Bd = Ca
d = Ca/B.

Determine the y-intercept of the graph of this equation: y - 3 = 2(x + 5)
Answer:
y intercept is 13
Step-by-step explanation:
y - 3 = 2(x + 5)
To find the y intercept, let x=0 and solve for y
y - 3 = 2(0 + 5)
y - 3 = 2(5)
y -3 =10
y-3+3 = 10+3
y = 13
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.
Amelia spent $37.29 on 2 pairs of pants. How much would she pay for one pair? Round to the nearest penny.
Answer:
$18.65
Step-by-step explanation:
[tex]\frac{y }{37.29} :\frac{1}{2}[/tex]
y · 2 = 1 · 37.29
2y = 37.29
2y ÷ 2 = 37.29 ÷ 2
y = 18.645
18.645 round to 18.65
What is the length of s=8.57, n=300, confidence level=95%
Answer:
The length of the interval is of 1.8672.
Step-by-step explanation:
Length of a confidence interval:
Margin of error multiplied by 2.
Confidence interval:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
s=8.57, n=300
[tex]\sigma = 8.25, n = 300[/tex]
Margin of error:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 1.96\frac{8.25}{\sqrt{300}}[/tex]
[tex]M = 0.9336[/tex]
Length:
2*0.9336 = 1.8672
The length of the interval is of 1.8672.

Step-by-step explanation:
use the graph to answer the questions.
1) Write in standard form
2) Identify the foci and asymptotes
3) find the domain and range
Answer:
Example: Locating a Hyperbola's Vertices and Foci
The hyperbola is centered at the origin, so the vertices serve as the y-intercepts of the graph. To find the vertices, set x=0 x = 0 , and solve for y y . Therefore, the vertices are located at (0,±7) ( 0 , ± 7 ) , and the foci are located at (0,9) ( 0 , 9 ) .

Answer:
96°
Step-by-step explanation:
The relevant relations are ...
the sum of arcs of a circle is 360°the measure of an inscribed angle is half the measure of the arc it intercepts__
The measure of arc HPQ is ...
arc HPQ = 360° -108° -60° = 192°
Then the measure of inscribed angle QRH is ...
∠QRH = (arc QPH)/2 = 192°/2
∠QRH = 96°

Which is the lowest rate? 8 cashiers for 96 people or 2 cashiers for 20 people
dana has already taken 3 pages of notes on her own, and she will take 2 pages durning each hour of class. write an equation that shows the relationship between the time in class h amd the number of pages p.
write your answer as an equation with p first, followed by an equals sign
Answer:
p = 2×h + 3
Step-by-step explanation:
for every hour in class she writes 2 pages.
so, the total number of pages written is 2 times the number of hours in class.
and she had already a starting "offset", a head start if you will, of 3 pages.
so, even if she spends 0 hours in class, she has these 3 pages no matter what.
hence the "+ 3" part.
