Answer:
x= 14/15
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x−13−3x4=562x+−13+−34x=56(2x+−34x)+(−13)=56
(Combine Like Terms)
54x+−13=5654x+−13=56
Step 2: Add 1/3 to both sides.
54x+−13+13=56+1354x=76
Step 3: Multiply both sides by 4/5.
(45)*(54X)=(45)*(76)x
=14/15

Your friend used the proportion 40/100 = 80/? To find 40% of 80 and says that the answer is 200. Complete the explanation as to why your friend is incorrect and find the correct answer.
Answer: See explanation
Step-by-step explanation:
My friends calculation is wrong. 40% of 80 is not 200. It is:
= 40% of 80
= 40/100 × 80
= 0.4 × 80
= 32
He should have represented the missing number by x. Therefore,
40/100 = 80/x
Cross multiply
(40 × x) = (80 × 100)
40x = 8000
x = 8000/40
x = 200
The figure shows ST
intersecting plane A at point V. a right angle. Points P, R, and
Q also lie in the plane.
Which statements are true based on the figure? Select all that apply.
Answer:
A,B,E,F those the answer i have EOC review packet done
Step-by-step explanation:
Points, lines and planes are undefined terms in geometry.
The true statements are:
(c) V lies on line ST(d) ST is perpendicular to plane A(e) ST is perpendicular to RVFirst, we test each option to determine the true and false options.
(a) S, V and U are collinear
Points that are collinear are on the same line
S, V and U are not collinear, because they are not on the same line.
Hence, (a) is false
(b) Q, S, T and U are coplanar
Points that are coplanar are on the same plane
Q, S, T and U are not coplanar, because they are not on the same plane.
Hence, (b) is false
(c) V lies on line ST
Point V is the point of intersection of line ST and plane A
This means that point V lies on line ST and plane A
Hence, (c) is true
(d) ST is perpendicular to plane A
Line ST intersects with plane A at point V at 90 degrees.
Perpendicular lines and planes meet at 90 degrees
Hence, (d) is true
(e) ST is perpendicular to RV
Because line ST intersects with plane A at point V at 90 degrees.
Any line drawn from point V would be perpendicular to line ST
Hence, (e) is true
(f) P, R and Q are collinear
Points that are collinear are on the same line
P, R and Q are not collinear, because they are not on the same line.
Hence, (f) is false

Move words to the blanks and equations to the boxes to prove that vertical angles <21 and <23 are congruent.
Answer:
See proof below
Step-by-step explanation:
From the given diagram, we can see that <2 and <3 lies on the same straight line, hence the sum of the angles is 180 degrees (supplementary)
<2 + <3 = 180 .... 1
Similarly. <1 and <2 are also supplementary angles
<1 + <2 = 180 .... 2
Subtract 1 from 2;
<3 - < 1 + <2 - <2 = 180 - 180
<3 - <1 +0 = 0
<3 - <1 = 0
Add <1 to both sides
<3 - <1 + <1 = 0+<1
<3 = <1 (Proved!)
This shows that <3 and <1 are equal
We can also conclude that <3 and <1 are vertically opposite angles and vertically opposite angles are equal
How many points does the team have?
How many games has this team lost?
Step-by-step explanation:
P = 3W + D
When W = 5 and D = 3, P = 3(5) + 3 = 18.
When P = 50 and D = 14,
(50) = 3W + (14), 3W = 36, W = 12.
Since the team has 12 wins and 14 draws,
they have 35 - 12 - 14 = 9 losses.

Bacteria growth. A colony of bacteria is grown under ideal conditions in a laboratory so that the population increases exponentially with time. At the end of 3 h there are 10,000 bacteria. At the end of 5 h there are 40,000 bacteria. How many bacteria were present initially
Answer:
1250 bacteria
Step-by-step explanation:
The formula for Exponential Growth is given as:
P(t)= Poe^rt
Where
P(t) = Population after time t
Po = Initial Population
r = growth rate
t = time
Hence, solving for the above question , we have to find Po
Making Po the subject of the formula
Po = P(t)/e^rt
Step 1
Find the Exponential growth rate
At the end of 3 h there are 10,000 bacteria.
Hence:
Po = 10000/e^3r.... Equation 1
At the end of 5 h there are 40,000 bacteria.
Po = 40000/e^5r..... Equation 2
Equating both equations together,
10000/e^3r = 40000/e^5r
Hence:
e^5r/e^3r = 40000/10000
e^2r = 4
Take the In of both sides
In (e^2r) =In 4
2r= In 4
r = In 4/2
r = In 2
Step 2
Solve for Po(Initial Population)
Using Equation 2
Po = 40000/e^5r..... Equation 2
r = In2
Po = 40000/e^5 × In 2
Po = 40000/2⁵
Po = 1250 bacteria.
Therefore, they was 1250 bacteria initially

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
Answer:
31.25 kg of flour is needed to make 50 cakes
Step-by-step explanation:
A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.
Flour needed to make 4 cakes = 2.5 kg
Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg
Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]
= 31.25 kg
So, 31.25 kg of flour is needed to make 50 cakes

Una nadadora entrenó todos los días durante 21días. El primer día nadó 15 minutos, y cada día nadaba 5 minutos más que el día anterior. ¿Cuánto tiempo nadó el último día? ¿Y a lo largo de las tres semanas? Expresa los resultados en horas y minutos.
Responder:
1 hora 55 minutos; 22 horas 45 minutos
Explicación paso a paso:
Dado que:
Tiempo el primer día = 15 minutos
Minutos adicionales cada día siguiente = 5 minutos
Número total de días
Usando la fórmula del enésimo término de una progresión aritmética:
Tn = A + (n - 1) d
A = primer trimestre = 15
d = diferencia común = 5
n = enésimo término
Tiempo de nado el último día (n = 21)
T21 = 15 + (21 - 1) 5
T21 = 15 + 20 * 5
T21 = 15 + 100
T21 = 115 minutos
= 1 hora 55 minutos
SEGUNDO.)
Suma de minutos durante las 3 semanas
Suma de n términos:
Sn = n / 2 * (primer término + último término)
Primer término = 15
Último trimestre = a21 = 115 minutos
n = número de términos = 21
Por lo tanto,
Sn = 21/2 * (15 + 115)
Sn = 10,5 * (130)
Sn = 1365 minutos
= 22 horas 45 minutos
