2-inch candle burns down in 8 hours. At what rate does the candle burn, in inches per hour?

The 1250 represents option B in the situation, George is correct, the solution to the linear equation is h = 80$.

What is a linear equation?

A linear equation has only one or two variables. No variable in a linear equation is raised to a power greater than one or used as the denominator of a fraction. When two values satisfying a linear equation are found and shown, all of the points on a coordinate grid fall on the same line.

Given that,

Jennifer was paid $15 per hour.

Given equation is 50+15h=1250

1)Here 1250 represent B.

Her financial situation towards the end of the summer.

Because as mentioned in the equation 50+15h=1250

Here, 50 is the money already there with her, and 15h was the amount paid to her,

So, by adding those both the amount 1250 will be the amount with Jennifer at the end of the summer.

2)Given equation is 50+15h=1250

By putting 10 in place of h (h=10)

50+15(10)=1250,

50+150=1250,

200=1250$.

Since, LHS is not equal to RHS.

Therefore, George is correct, 10 could not be the solution to the linear equation.

3) Given equation 50+15h=1250

15h=1250-50,

15h=1200,

h=1200/15,

h=80$.

Therefore, the solution for the equation h is 80$.

Answer:

A. 24.17.

Step-by-step explanation:

Perimeter of given triangle

Step-by-step explanation:

subtract 70 from both sides of the equation

We get the expression 64√2 in the form 2ⁿ as 2⁶°⁵.

An expression is a way in which numbers are written.

It can be variables, constants or a combination of both.

We are given an expression:

64 √2

We know that:

64 = 2 × 2 × 2 × 2 × 2 × 2

64 = 2⁶

Also, we can write √2 as

√2 = 2⁰°⁵

We get that:

2⁶ × 2⁰°⁵

simplifying the expression, we get that:

= 2⁶⁺⁰°⁵

= 2⁶°⁵

Therefore, we get the expression 64√2 in the form 2ⁿ as 2⁶°⁵.

Step-by-step explanation:

Since both bags of sugar were 120 kg, there is a total of 240 kg of sugar to be distributed into the packs. Let x represent the number of 2 kg packets and y represent the number of 3 kg packets. We know that all the sugar was packed into these two kinds of packets, so:

[tex]2x+3y=240[/tex]

And we know that there were half as many 2 kg packets as 3 kg packets, so:

[tex]x=\frac{1}{2} y[/tex]

Now, we have a system of equations!

[tex]\left \{ {{2x+3y=240} \atop {x=\frac{1}{2}y }} \right.[/tex]

Let's put the second equation equal to y, since that removes the fraction:

[tex]x=\frac{1}{2}y\\ 2x=y[/tex]

Now substitute y into the first equation:

[tex]2x+3y=240\\2x+3(2x)=240[/tex]

Now simplify to find x:

[tex]2x+3(2x)=240\\2x+6x=240\\8x=240\\x=30\\[/tex]

There are 30 of the 2 kg packets! Now, we can use x to find y, the number of 3 kg packets!

[tex]2x=y\\2(30)=y\\60=y[/tex]

There are 60 of the 3 kg packets!

The profit decreased by 20% at the end of January

Therefore decrease percentage, which is used to determine the percentage decrease of two values ​​(final value and initial value)

[tex]Decrease percentage = \frac{Final value - Initial Value}{Final Value} * 100[/tex]

According to the formula, the initial value is subtracted from the final value. The resulting value is divided by the initial value and multiplied by 100 to obtain the decreased percentage

Final value = $15000

[tex]20 = \frac{15000 - Initial Value}{15000} * 100[/tex]

If Ty has 4 field goals and 3 touchdowns, he cannot remain on the team.

Here are inequality signs and what they mean:

The inequality sign that would be used is ≤ because Ty's score has to be at most 18 points.

The from of the inequality that describes the constraints is:

(point of a touchdown x number of touchdowns) + (point of field goals x number of field goals) ≤ maximum points

(1 x f) + (6 x t) ≤ 18

Married filing separately is a tax status for married couples who choose to record their respective incomes, exemptions, and deductions on separate tax returns.

The alternative to married filing separately is married filing jointly. Usually, it makes sense financially for married couples to file jointly. However, when one spouse has significant medical expenses or miscellaneous itemized deductions, or when both spouses have about the same amount of income, it might be wiser to file separately.

If the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10, then cost of 1 kg of turnips is £1.1 and cost of 1 kg of mushrooms is £2.9.

Given that the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10.

We are required to find the cost of 1 kg of mushrooms and the cost of 1 kg of turnips.

Cost is basically the expenditure that we do in order to buy or produce a product.

Suppose the cost of 1 kg of mushrooms be x and the cost of 1 kg of turnips be y. The equations will be as under:

2x+2.5y=8.55------1

3x+4y=13.10-------2

Equation1 *3 and Equation2 *2.

6x+7.5y=25.65-----3

6x+8y=26.20-------4

Subtract 4 from 3.

6x+7.5y-6x-8y=25.65-26.20

-0.5y=-0.55

y=1.1

Put the value of y in 1.

2x+2.5*1.1=8.55

2x+2.75=8.55

2x=8.55-2.75

2x=5.80

x=2.9

Hence if the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10, then cost of 1 kg of turnips is £1.1 and cost of 1 kg of mushrooms is £2.9.

The price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000

Let the price of the cycle be x

Then the price of the scooter will become X + 4200

As the price of a scooter and the price of a cycle are in the ratio of 5:2

So, it can be written as

 x+4200: x:: 5:2

which implies

x= 2a and x+4200= 5a

a= x/2 and x+4200/5

equating both the equations, we get

x/2=(x+4200)/5

in order to solve this linear equation, we need to move 2 from the left-hand side to the right-hand side which would result in the change of sign from division to multiplication and we need to move 5 from the right-hand side to the left-hand side which would result in the change of sign from division to multiplication

5x=2x+8400

3x= 8400

X= 8400/3
