Answer:
The cost of one taco is $0.87 and the cost of one enchilada is $1.16
Step-by-step explanation:
Let the cost of tacos be X
and cost of enchiladas be y
So, by using given data, we have following equations
3X + 2Y = 4.93 (1)
2X + 4Y = 6.38 (2)
So, first multiply 1st equation by 2 and 2nd equation by 3, then subtracting 1st equation by 2nd.
= 2 × ( 3X + 2Y = 4.93) (1)
= 3 × (2X + 4Y = 6.38) (2)
= - (6X + 4Y = 9.86) (1)
= 6X + 12y = 19.14 (2)
= 8Y = 9.28
Y = 9.28 ÷ 8 = 1.16
By putting the value of Y in equation 1, we get
3X + 2(1.16) = 4.93
3X + 2.32 = 4.93
X = 2.61 ÷ 3 = 0.87
Hence, the cost of one taco is $0.87 and the cost of one enchilada is $1.16.

Step-by-step explanation:
A car starts from rest and attains a velocity of 9km/h in 5 seconds . Calculate acceleration and the displacement covered in that time
Answer:
Acceleration is 0.5 m/s² and the distance covered is 6.25 m.
Step-by-step explanation:
Given that,
Initial speed, u = 0
Final speed, v = 9 km/h = 2.5 m/s
Time, t = 5 seconds
We need to find the acceleration and the displacement covered in that time. Acceleration = rate of change of velocity
So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.5-0}{5}\\\\a=0.5\ m/s^2[/tex]
Distance d can be calculated using third equation of motion.
[tex]d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{2.5^2-0^2}{2\times 0.5}\\\\d=6.25\ m[/tex]
So, acceleration is 0.5 m/s² and the distance covered is 6.25 m.

A person invested $3,500 in an account growing at a rate allowing the money to double every 15 years. How long, to the nearest tenth of a year would it take for the value of the account to reach$7,700?
Answer:
30 years and a half
Step-by-step explanation:
well let's just say 3.5k x hmm 2? at an estimate and that will get us to 7000.. so in order to get to 7000 we have to wait 15 years which is 30 years and a half. From Xthermyx. A brainly user.
It would take 22.7 years for the value of the account to reach $7,700.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Since the money in the account is doubling every 15 years.
The following equation is used to find the time it takes to reach a certain value:
t = (ln(P/F))/(ln(1+r))
where:
P = the initial investment amount
F = the future value we want to reach
r = the growth rate per period
ln = natural logarithm
t = the number of years it takes to reach F
P = $3,500
F = $7,700
r = ln(2)/15 (since the money is doubling every 15 years).
Plugging these values into the equation.
t = (ln(3500/7700)) / (ln(1+ln(2)/15))
t = ln (5/11) / ln (1 + 0.30/15)
t = 22.7
Therefore,
It would take 22.7 years for the value of the account to reach $7,700.

The length of a planet's orbit around a star is approximately 22,200,000 km.
It takes the planet about 1230 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answer:
Speed = 7520 km/h
Step-by-step explanation:
Given the following data;
Distance = 22,200,000 km.
Time = 1230 Earth days
To find the average speed of the planet;
First of all, we would have to convert the time in Earth days to hours;
1 Earth day = 24 hours
1230 Earth day = x
Cross-multiplying, we have;
x = 1230 * 24
x = 29520 hours
Therefore, time = 29520 hours
Substituting into the formula, we have;
Speed = 22200000/29520
Speed = 7520.325 km/h
To 3 significant figures;
Speed = 7520 km/h
I don’t understand question 42,43
Answer:
42. x = 25
43. LM = 11
Step-by-step explanation:
For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.
So: 90 + 2x + x + 15 = 180
105 + 3x = 180
3x = 75
x = 25
If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180
For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.

Suppose you invest $130 a month for 5 years into an account earning 8% compounded monthly. After 5 years, you leave the money, without making additional deposits, in the account for another 25 years. How much will you have in the end?
Answer:
FV= $70,887.15
Step-by-step explanation:
First, we need to calculate the future value of the $130 deposit for 5 years:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit= $130
i= 0.08/12= 0.0067
n= 5*12= 60 months
FV= {130*[(1.0067^60) - 1]} / 0.0067
FV= $9,561.96
Now, using the following formula, the future value of the investment after 25 years:
FV= PV*(1 + i)^n
n= 25*12= 300
FV= 9,561.96*(1.0067^300)
FV= $70,887.15
