Cora ran 3 miles last week and will run 7 miles per week from now on. Hana ran 9 miles last week and will run 4 miles per week from now on.

In the answer box,
Write a system of equations to describe this scenario. Identify what the variables mean in the context of the problem.

Answers

Answer 1

Answer:

If Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x. Then determine how many weeks are in two and a half months (depends on which month it is as there are less weeks in February than in January!) but we could estimate 6.

For Hana, you will have 3+ 3/4 x

Step-by-step explanation:

First equation is y=5+1/2 x and then plug 6 in for x to solve for y. the second equation is y=3+3/4x and plug in 6.

Answer 2

The system of equations to describe this scenario are

y = 3 + 7xy = 9 + 4x

The variable x means the number of weeks they ran and the y variable means the total distance they covered in miles .

The situation can be modelled like a linear equation.

Therefore,

y = mx + b

where

m = slope

b = y-intercept

Cora race will be as follows:

y = 3 + 7x

Hana race will be as follows:

y = 9 + 4x

The variable x which is the independent variable is the number of weeks each of them ran in the equation.

The variable y which is the dependent variable is the total distance covered in miles.

Answers

they take 6 hours  to paint the garage if the two of you paint together.

It will take you 10 hours to paint your garage

it will take your brother 15 hours to paint your garage.

How long will it take to paint the garage if the two of you paint together

Total work = LCM of 10 and 15 = 30 units

now , it will take 10 hours to paint the garage

therefore it one hour efficiency = 30/10 =3 units

similarly your brother take 15 hours to apint the garage

therefore brother one hour efficiency = 30/15 = 2 units

so total one hour efficiency is 5 units

and total work is 30 units and their one hour efficiency is 5 units

therefore they complete the work in 30 /5 = 6 hour

Hence they take 6 hours  to paint the garage if the two of you paint together.

Anil Kumar took a loan of Rs. 20,000 from bank at the rate of 8% per annum. At the end of 2 years, how much compound amount should he pay if the interest was compounding half-yearly? ​

Answers

Anil Kumar should pay a compound amount of Rs. 23,397.12 at the end of 2 years.

Compound interest is a method of calculating interest where the interest earned is added to the principal amount, and the resulting sum becomes the new principal for the next period's interest calculation. This process is repeated until the end of the investment period.

The formula to calculate the compound interest is:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

Where,

A = Amount after the given time

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times the interest is compounded per year

t = Time duration for which the interest is calculated (in years)

In this case, Anil Kumar took a loan of Rs. 20,000 from a bank at the rate of 8% per annum, compounded half-yearly, for 2 years. Therefore, we can plug in the values as follows:

P = Rs. 20,000

r = 8% per annum = 0.08 (as a decimal)

n = 2 (since the interest is compounded half-yearly)

t = 2 years

Now, we can calculate the compound amount using the above formula:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

[tex]A = 20,000(1 + 0.08/2)^(^4^)[/tex]

[tex]A = 20,000(1 + 0.04)^4[/tex]

[tex]A = 20,000(1.04)^4[/tex]

[tex]A = 23397.1712[/tex]

Therefore, Anil Kumar should pay a compound amount of Rs. 23,397.123 at the end of 2 years.

Answer: 120.

Step-by-step explanation: the angles of a triangle add up to 180 degrees.  angles c and d are given and their values add up to 120 degrees. so E must be 180-120, which equals 60 degrees. We also know that a straight line is 180 degrees and since one side is 60 degrees, the other one must add up with 60 to give 180, which is 120.

Help me find the X! UwU..

Answers

It's x=60 because it's equilateral

Well all the angles in a triangle add up too 180º and this triangle is obviously a equilateral triangle (all sides are same) BUT as you see the other people saying X = 60º notice that it says 2 xº meaning that it is X x 2 so 60º is actually wrong :).

If it is X is 60º (since the 3 angles add together since it’s equilateral) then that would be 2 x 60º = 120º times 3 WHICH IS NOT 180.I think U get what I mean now,it’s 2 Xº; so X is 30 because 30 x 2 = 60º and 60 x 3 = 180º!

So Da Answer is X = 30º

What’s the value of k ?

Answers

Hello!

[tex]\large\boxed{k = 10^{o}}[/tex]

When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:

m∠YZX + m∠ZXY ≅ m∠MYZ

(4k + 5)° + (6k + 10)° = 115°

Combine like terms:

10k + 15 = 115°

Subtract 15 from both sides:

10k = 100°

Divide both sides by 10:

k = 10°

Answer:

k=10

Step-by-step explanation:

First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.

Second you would set the equations equal to 115

4k+5+6k+10=115

Then you would combine the like terms

10k+15=115

next you would subtract the 15 from both sides

10k=100

then you divide by 10

k=10

You have $50 in your bank account. Each week you plan to deposit $6 from your allowance and $20 from your paycheck. The equation b = 60 + (20+6)w gives the amount b in your account after w weeks. How many weeks from now will you have $215 in your bank account?

Answers

6 weeks from now, you will have $215 in your bank account

How many weeks from now will you have $215 in your bank account?

The given parameters are:

b = 60 + (20+6)w

When the account balance is $215, we have

60 + (20+6)w = 215

Subtract 60 from both sides

(20+6)w = 155

This gives

26w = 155

Divide both sides by 26

w = 5.96

Approximate

w = 6

Hence, 6 weeks from now, you will have $215 in your bank account

A right triangle has one leg with a length of 18 mm and a hypotenuse with a length of 82 mm.
What is the length of the other leg?
Your answer

Answers

Answer:

80 mm

Step-by-step explanation:

Pythagorean theorm can be applied here to solve for the length of the last leg, [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex], where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:

b = √c^2 - √a^2

  = √(82)^2 - √(18)^2

  = √6724 - √324

  = √6400

the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.

We need to find the distance between two points which is the hypotenuse of the triangle:

(8, 7) and (6, 3)

It can be calculated using distance formula:

D = √ (x₂ - x₁)² + (y₂ - y₁)²

Substituting the values in the formula, we get that:

D = √ (6 - 8)² + (3 - 7)²

D = √ ( - 2 )² + ( - 4 )²

D = √ 4 + 16

D = √ 20

∠6=116°

Step-by-step explanation:

Buckle up :)

We are given the values of ∠4 [tex](-2x+94)[/tex] and ∠8 [tex](-5x+139)[/tex].Vertical angles are congruent. Angle 4 and angle 1 are vertical angles, so angle 1 is also [tex]-2x+94[/tex].∠1 and ∠8 are alternate exterior angles. The transversal is the line that crosses over the parallel lines. When two angles are on opposite sides of the transversal, they are alternate angles. When the two angles are on the outside of the parallel lines, they are exterior angles. This makes them alternate-exterior angles.Alternate exterior angles are congruent. This means that ∠1≅∠8. Write an equation in order to solve for x:

[tex]-2x+94=-5x+139[/tex]

Solve for x. Subtract 94 from both sides:

[tex]-2x+94-94=-5x+139-94\\\\-2x=-5x+45[/tex]

Add 5x to both sides:

[tex]-2x+5x=-5x+5x+45\\\\3x=45[/tex]

Divide both sides by 3:

[tex]\frac{3x}{3} =\frac{45}{3} \\\\x=15[/tex]

Insert the value of x into angle 4 because they are same-side interior angles. This is because they are on the same side of the transversal and within the parallel lines. Same-side interior angles are supplementary, so their value will add up to 180°. Therefore, in order to find angle 6, we need to first find the true value of angle 4:

[tex]x=15\\\\-2(15)+94\\\\-30+94\\\\64[/tex]

∠4 is 64°. Use ∠a+∠b=180 to find angle 6:

[tex]a+64=180[/tex]

a represents angle 6. Subtract 64 from both sides:

[tex]a+64-64=180-64\\\\a=116[/tex]

Angle 6 has a measure of 116°.

Solving for the variable 'f' gives f = 100 - 2h/5

What is subject of formula?

A subject of formula can be defined as the variable that is expressed in terms of other variables in a given expression, function of equation.

It is the variable that is worked out in an equation and left to stand on its own on one side of the equality sign

Given the equation;

5f+2h = 100

To make 'f' the subject of formula, we take the following steps;

Take '2' over the equality sign

5f = 100 - 2h

Now, let's make 'f' the subject by dividing both sides by its coefficient which is 5

We have;

5f/5 = 100 - 2h/5

Divide through

f = 100 - 2h/5

Thus, solving for the variable 'f' gives f = 100 - 2h/5

The field trip took place at a theater.

The theater has a total of 3200 seats.

The 6th-grade students filled 2112 of the seats in the theater.

To calculate the percentage of seats filled by the 6th-grade students:

Use the formula =  (Number of seats filled / Total number of seats) x 100.

In this case,

The number of seats filled by the 6th-grade students is 2112, and the total number of seats in the theater is 3200.
