Rose would be saving 50 dollars after 10 months. So you know that Rose got $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.

Final Result: 50

Answer:

  No

Step-by-step explanation:

If all 30 coins were nickels and dimes, there would be 10 dimes and 20 nickels, for a total value of $2.00. Trading a dime and 2 nickels for an equal number of quarters raises the value to $2.00 -0.10 -2(0.05) +3(0.25) = $2.55.

That is, each such trade adds $0.55 in value to the total amount. Since the original difference of $3.00 -$2.00 = $1.00 is not evenly divisible by $0.55, there cannot be twice as many nickels as dimes.

__

For 30 coins, possible numbers of {nickels, dimes, quarters} are ...

{21,2,7}, {18,6,6}, {15,10,5}, {12,14,4}, {9,18,3}, {6,22,2}, {3,26,1}, {30 dimes}

Note that we can have 1.5, 3, or 10.5 times as many nickels as dimes, but not 2 times as many.

Answer:

0.20 hour

Step-by-step explanation:

According to the problem, computation of the given data are as follows,

Speed of police = 90 mph

Speed of chased car = 85 mph

Distance to be chased = 1 mile

So, we can calculate the time to catch by using following formula:

Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)

= 1 ÷ ( 90 - 85)

= 1 ÷ 5

= 0.20 hour

Answer:

9 books

Step-by-step explanation:

78=b(6)+c(4)

78=9(6)+6(4)

78=54+24

78=78-True

As per linear equation, Cindy bought 9 books online.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

Given, Cindy was buying books ($6 each) and candles ($4 each).

She bought 15 items and spent $78.

Let, she bought 'x' books.

Therefore, she bought (15 - x) candles.

Now, the cost of the total 15 items is

= $[6x + 4(15 - x)]

= $[6x + 60 - 4x]

= $[2x + 60]

Therefore, 2x + 60 = 78

⇒ 2x = 78 - 60

⇒ 2x = 18

⇒ x = 9

Therefore, Cindy bought 9 books.

Answer: ‭6,520‬ miles per year

Step-by-step explanation:

They had driven the car for 53,790 miles in 8.25 years.

The average number of number of miles driven per year is:

= ‭6,520‬ miles per year

They drove an average of ‭6,520‬ miles per year.

Answer:

Dimes = x = 52

Nickels = y = 39

Step-by-step explanation:

Let

Dimes = x

Nickels = y

x + y = 91 (1)

0.10x + 0.05y = 7.15 (2)

From (1)

x = 91 - y

Substitute x = 91 - y into (2)

0.10x + 0.05y = 7.15

0.10(91 - y) + 0.05y = 7.15

9.10 - 0.10y + 0.05y = 7.15

- 0.10y + 0.05y = 7.15 - 9.10

-0.05y = -1.95

y = -1.95 / 0.05

= 39

Substitute y = 39 into (1)

x + y = 91

x + 39 = 91

x = 91 - 39

x = 52

Dimes = x = 52

Nickels = y = 39

Answer:

30.12-215

Step-by-step explanation:

We get the value  22.14 - 593.42 for the given expression 31/7(5-56-78)

An expression is combination of variables, numbers and operators.

The given expression is 31/7(5-56-78)

Thirty one divided by seven times of five minus fifty six minus seventy eight

31/7(5-56-78)

31/7(5-134)

Thirty one by seven times of five minus one hundred thirty four.

31/7(5)-31/7(134)

155/7-4154/7

22.14 - 593.42

Hence, we get the expression 22.14 - 593.42 for the given expression 31/7(5-56-78)

Step-by-step explanation:

Assuming that the equation is y = 10x + 1

(12, 4)

4 = 10(12) + 1

4 = 120 + 1

4 ≠ 121

(12, 4) is not a solution.

(1, 1.5)

Answer:

steps below

Step-by-step explanation:

2 kinds of larger shapes can be make

kind 1: 18 x 4 x 3 = 216 cm

kind 2: 18 x (5+5+4) = 252 cm

The perimeter of the larger shape formed by putting three regular hexagons together is 216 cm.

When three regular hexagons are put together to form a larger shape, they form a regular hexagon with an equilateral triangle at each end.

The perimeter of the larger shape can be calculated as follows:

Perimeter of larger shape = Perimeter of hexagon + Perimeter of equilateral triangle

Since the hexagon has six sides of equal length, its perimeter is [tex]\(6 \times 18 \, \text{cm} = 108 \, \text{cm}\)[/tex].

Each equilateral triangle has three sides of equal length, and each side of the equilateral triangle is equal to one side of the hexagon.

So, the perimeter of each equilateral triangle is [tex]\(3 \times 18 \, \text{cm} = 54 \, \text{cm}\)[/tex].

Since there are two equilateral triangles, the total perimeter contributed by the equilateral triangles is [tex]\(2 \times 54 \, \text{cm} = 108 \, \text{cm}\)[/tex].

Finally, to find the perimeter of the larger shape, add the perimeters of the hexagon and the two equilateral triangles:

Perimeter of larger shape = 108 cm + 108 cm = 216 cm

Thus, the perimeter of the larger shape is [tex]\(216 \, \text{cm}\)[/tex].

Answer:

The roots are [tex]x=\dfrac{-7+ \sqrt{97}}{2}\text{ and }x=\dfrac{-7- \sqrt{97}}{2}[/tex].

Step-by-step explanation:

Consider the provided equation.

[tex]2(6 - x) = x(x + 5)[/tex]

Remove the parenthesis and simplify.

[tex]12-2 x= x^2 + 5x[/tex]

[tex]x^2+7x-12=0[/tex]

Now use the quadratic formula [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex].

Susbtitute a=1, b=7 and c=-12 in above formula.

[tex]x=\dfrac{-7\pm \sqrt{7^2-4(1)(-12)}}{2(1)}[/tex]

[tex]x=\dfrac{-7\pm \sqrt{49+48}}{2}[/tex]

[tex]x=\dfrac{-7\pm \sqrt{97}}{2}[/tex]

Hence, the roots are [tex]x=\dfrac{-7+ \sqrt{97}}{2}\text{ and }x=\dfrac{-7- \sqrt{97}}{2}[/tex].
