Answer:

61

Step-by-step explanation:

if it dropped 6 degrees, you would add 6 to the current temperature to get 61 (55+6=61)

Answer:

61 degrees

Step-by-step explanation:

it is 55 degrees now. it had dropped 6 degrees in an hour. since it went down and subtracted 6 degrees, we would have to do the other order of operation which in this case is addition. 55 plus 6 is 61. ( message me if you need more help)

Answer:

DNE (dose not exist)

Step-by-step explanation:

what you would do is just set both functions equal to each other and then solve for x. so set x+109=x+89. then get you numbers on one side and your x's on one side. so subtract x from on side getting x-x+89=109 now you subtract 89 from both sides getting x-x=109-89 getting 0= 20 0 dosen not = 20 so you would have zero there is no value that you could plug in for x to get them both equal

Answer:

17.5

Step-by-step explanation:

so 4 cans is 2.5$ each so i did 2.5 times 7 to see how much it would be for 7 cans

To find the cost of 7 cans of fruit cocktails, you first determine the price per can at $2.50 by dividing the cost for 4 cans ($10) by 4. Multiplying the price per can by 7 gives the total cost, which is $17.50.

To find the price of 7 cans of fruit cocktails when 4 cans are sold for $10, we need to calculate the price per can and then multiply by the desired number of cans.

Step-by-step calculation:

Therefore, 7 cans of fruit cocktails will cost $17.50.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

Given:

3x = 6x - 2

3x-6x= -2

-3x= -2

x= -2/-3

x= 2/3

Hence, the value of x is 2/3

Answer:

(-1,-5)

Step-by-step explanation:

Starting at (0,0), we perform the first translation:

T<5,-7> implies that we move the point 5 units to the right (in the x (horizontal) direction), and 7 units DOWN in the y <vertical) direction.

From there we do the second translation: T<-6,2>

which means: 6 units to the left (in the horizontal direction) which takes us to  "-1" for the x value, and 2 units up (vertical) which takes us to -5 for the y value.

Therefore the new location is (-1,-5)

Answer: 206

Answer:

Answer is = 6

Step-by-step explanation:

The problem involves determining the area of material purchased, comparing the quantities, and solving for the width given certain conditions. After setting up and solving the equations, it was found that the width of the material is 3 metres and the total amounts of material purchased by Annie and Bronwyn are 4 and 15 square metres respectively.

To solve the problems related to the area of material purchased by Annie and Bronwyn, follow these steps:

Area of material: Given the width of the material is (x + 2) metres, Annie buys (x + 3) metres long and Bronwyn buys 5 metres long. The area for each piece of material purchased is the product of the width and length. So, Annie's material area is (x + 2)(x + 3) square metres, and Bronwyn's material area is 5(x + 2) square metres.

More material: To express how much more material Annie has than Bronwyn, subtract Bronwyn's area from Annie's area, which gives us ((x + 2)(x + 3) - 5(x + 2)) square metres.

Factorisation: The expression for how much more material Annie has than Bronwyn can be factorized as (x + 2)(x - 2) square metres after simplifying.

Width of material: If Annie has 5 square metres more material than Bronwyn, we solve the equation (x + 2)(x - 2) = 5. Solving this quadratic equation gives x = 1, the width of the material is therefore 3 metres.

Total material: With x = 1, Annie purchases 4 square metres (since 3 x 1 + 3) and Bronwyn purchases 15 square metres (since 5 x 3). So, Annie has 4 square metres of material and Bronwyn has 15 square metres.

Answer:

$3,113,34

Step-by-step explanation:

The formula for calculating compound interest is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where

A=the future total value, i.e, the money you will have after t years.

P=the initial deposit.

r=the annual interest rate.

n=the number of times that interest is compounded per year.

t=the number of years the money is saved.

In our case

A is unknown and we will have to calculate it with the formula.

P=$12,000

r=2.9%=0.029

n=365 because the interest is compounded daily and there are 365 days in a year

t=8 years

Applying the formula we get

[tex]A=12,000(1+\frac{0.029}{365})^{365\times8}[/tex]

[tex]A=12,000(1+\frac{0.029}{365})^{2,920}[/tex]

[tex]A=12,000(1.000079)^{2,920}[/tex]

So A=15,113.336

This is the amount of money you would have after 8 years.

Subtracting the initial deposit from this amount we obtain the interest earned I

I=15,113.336-12,000=3,113.336

Rounded to the nearest hundreth

I=$3,113,30

Answer:

x = 10

Step-by-step explanation:

Begin by factorising the numerator/ denominator of the left side

x² - 14x + 49 = (x - 7)² ← perfect square

x² - 49 = (x - 7)(x + 7) ← difference of squares

Thus left side becomes

[tex]\frac{(x-7)^2}{(x-7)(x+7)}[/tex] → x ≠ ± 7

Cancel (x - 7) on numerator/denominator, leaving

[tex]\frac{x-7}{x+7}[/tex]

Returning to the equation, that is

[tex]\frac{x-7}{x+7}[/tex] = [tex]\frac{3}{17}[/tex] ( cross- multiply )

17(x - 7) = 3(x + 7) ← distribute both sides

17x - 119 = 3x + 21 ( subtract 3x from both sides )

14x - 119 = 21 ( add 119 to both sides )

14x = 140 ( divide both sides by 14 )

x = 10

Answer:

2x+6

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

The mean is measured as

mean = [tex]\frac{score}{count}[/tex]

After 5 tests the mean is 84, that is

[tex]\frac{score}{5}[/tex] = 84 ( multiply both sides by 5 )

score = 420

let the sixth test score be x, then

[tex]\frac{420+x}{6}[/tex] = 85 ( multiply both sides by 6 )

420 + x = 510 ( subtract 420 from both sides )

x = 90

Require to score 90 on the sixth test

(Hint which is the first number on both factors :))

Lauren will visit both the park and the library on the same day again after 30 days. This is because the least common multiple (LCM) of 3 and 10 is 30.

The subject of this question is Mathematics, particularly dealing with the concept of least common multiple (LCM). The question is asking when will Lauren visit the park and the library on the same day again. Given that Lauren goes to the park every 3 days and the library every 10 days, the day when she'll do both again is the least common multiple of 3 and 10.

The least common multiple (LCM) is the smallest multiple that is exactly divisible by every member of a set of numbers. In this case, we need to determine the LCM of 3 and 10. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ... The multiples of 10 are 10, 20, 30, 40, .... As we can see, the smallest number that appears in both lists is 30. Therefore, Lauren will visit both the park and library on the same day again after 30 days.

Check the picture below.

sure, since y = 0 is a line, in essence the x-axis really, that goes to infinity, so we can draw an infinite amount of perpendicular lines on it all the way.

The equation for a line perpendicular to the line y=0 is x=a, where a is the x-coordinate of the point where the line intersects the x-axis. There are infinitely many lines that are perpendicular to the line y=0. For example, the line x=3.

The equation for a line perpendicular to the line y=0 is simply the equation for a vertical line passing through any point on the x-axis. A vertical line is defined by the equation x = a, where a is the x-coordinate of the point where the line intersects the x-axis.

Since the line y=0 is also the x-axis, any vertical line passing through a point on the x-axis will be perpendicular to it. Therefore, there are infinitely many lines that are perpendicular to the line y=0.

For example, the equation for a line perpendicular to y=0 passing through the point (3,0) would be x=3.

The slope of the ladder to the building is 2/3

Step-by-step explanation:

* Lets explain how to find the the slope of the ladder

- A ladder leaning against the side of a building touches the building

 at a point 12 meters from the ground

* That means the height of the ladder (h) from the ground is 12 m

- The foot of the ladder is 18 meters from the base of the building

* That means the horizontal distance (d) on the ground between the

  ladder and the building is 18 m

- The slope of the ladder (m) , the height of the ladder (h) and the

  horizontal distance on the ground from the base of the ladder to

  the base of the building (d) can form a right triangle

∵ The slope of the ladder = the vertical distance/horizontal distance

∵ The vertical distance h is 12 meters

∵ the horizontal distance d is 18 meters

∴ The slope of the ladder [tex]m=\frac{12}{18}=\frac{2}{3}[/tex]

∴ The slope of the ladder to the building is 2/3

Answer:

2/3

Step-by-step explanation:
