The ratio of chocolate cookies to sugar cookies in a bakery box is 2:1. What is the ratio of sugar cookies to total cookies?

[tex]Domain:\\\\x-5\geq0\to x\geq5\\\\\sqrt{x-5}+7=11\ \ \ \ \ |-7\\\\\sqrt{x-5}=4\ \ \ \ \ |^2\\\\(\sqrt{x-5})^2=4^2\to x-5=16\ \ \ \ \ |+5\\\\\boxed{x=21}\in D\\\\[/tex]

We have the following equation:

[tex]\sqrt{x-5} +7=11[/tex]

To solve this, we first need to subtract the 7 on both sides of the equation.

[tex]\sqrt{x-5} +7-7=11-7[/tex]

The equation then becomes:

[tex]\sqrt{x-5} =4[/tex]

Now we must square both sides of the equation to get rid of the radical/square root symbol.

[tex](\sqrt{x-5})^2 =(4)^2[/tex]

Now we have a normal one step equation.

[tex]x-5=16[/tex]

Add 5 on both sides to find x.

[tex]x-5+5=16+5[/tex]

x=21

To see if this solution is true, we must substitute 21 back into the original equation.

[tex]\sqrt{21-5} +7=11[/tex]

[tex]\sqrt{16} +7=11[/tex]

[tex]4+7=11[/tex]

11=11

Therefore, the solution is true.

Well if you divide 30 by 10 then multiply by 4 you get 12 minutes.

Do the same for 45,

45 divided by 10 = 4.5 then multiply by 4 =  18

The number of miles the train will travel at the same speed is 18 miles

From the question,

We are to determine the number of miles the train travel in 12 minutes

From the question

It takes an express train 30 minutes to travel 45 miles

First, we will determine the speed

From the formula

[tex]Speed = \frac{Distance}{Time}[/tex]

Distance = 45 miles

Time = 30 minutes

∴ [tex]Speed = \frac{45}{30}[/tex]

Speed = 1.5 miles/mins

Now,

For the number of miles the train travel in 12 minutes

Time = 12 minutes

Using the formula

Distance = Speed × Time

∴ Distance = 1.5 × 12

Distance = 18 miles

Hence, the number of miles the train will travel at the same speed is 18 miles

Answer:

The unit rate for the price to the length of the fabric will be $8 per meter.

Step-by-step explanation:

The two points on the graph of the line are:  (1, 8) and (3, 24)

For finding the unit rate for the price to the length of the fabric, we just need to find the slope of that line.

Formula for finding the slope is:  [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] are two given points.

Here,  [tex](x_{1}, y_{1})=(1,8)[/tex] and [tex](x_{2}, y_{2})=(3, 24)[/tex]

So, the slope of the line will be:  [tex]m= \frac{24-8}{3-1}= \frac{16}{2}= 8[/tex]

Thus, the unit rate for the price to the length of the fabric will be $8 per meter.

The unit rate for the price to the length of the fabric is $8/m

from the question, we have the following parameters that can be used in our computation:

The graph

The unit rate is calculated as

Unit rate = Change in y/x

using the above as a guide, we have the following:

Unit rate = (24 - 8)/(3 - 1)

Evaluate

Unit rate = 8

X= -2

Step-by-step explanation:

I'm sorry if my addition signs looks like division signs

5X + 2 ( X - 4 ) = 5X + X - 10

5X + 2X - 8 = 5X + X - 10

7X - 8 = 6X - 10

add 8 on both sides

7X = 6X - 2

The equation of line will be;

⇒ y = 5x - 3

What is Equation of line?

The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The perpendicular line is,

y = -1/5x - 3

And, The point contain by the line = (1 , 2)

Now,

We need to find the slope of line.

Since, Product of slopes of perpendicular lines are - 1.

So, we find the slope of perpendicular line as;

y = -1/5x - 3

dy/dx = -1/5

So, The slope of the line = - (1/-1/5) = 5

Hence, The equation of line passing through the points (1, 2) and with slope 5 is defined as;

y - y₁ = m (x - x₁)

y - 2 = 5 (x - 1)

y - 2 = 5x - 5

y = 5x - 5 + 2

y = 5x - 3

Thus, The equation of line will be;

⇒ y = 5x - 3

factor out the five

5(x^2+5)   D

Final answer:

The four points on the line with a slope of 0.2 and y-intercept of 0.3 are (0, 0.3), (1, 0.5), (2, 0.7), and (3, 0.9).

Explanation:

The equation of the line can be written in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 0.2 and the y-intercept is 0.3. To find four points on the line, we can choose any x-values and substitute them into the equation to find the corresponding y-values.

For example, let's choose x = 0, 1, 2, and 3:

When x = 0, y = 0.3

When x = 1, y = 0.5

When x = 2, y = 0.7

When x = 3, y = 0.9

So, the four points on the line with a slope of 0.2 and y-intercept of 0.3 are (0, 0.3), (1, 0.5), (2, 0.7), and (3, 0.9).

Answer:

49 seconds.

Step-by-step explanation:

We have been given that an elevator ascends at a rate of 29.6 feet per second. A building is 1,450 feet tall. We are asked to find the time it will take for the elevator to travel from the ground floor to the roof.

To find the time taken by elevator to reach the top of the building, we will use rate formula.

[tex]\text{Time}=\frac{\text{Distance}}{\text{Rate}}[/tex]

[tex]\text{Time}=\frac{\text{1450 ft}}{\frac{\text{29.6 feet}}{\text{second}}}[/tex]

[tex]\text{Time}=\frac{\text{1450 ft}}{\text{29.6 feet}}\times\text{second}[/tex]

[tex]\text{Time}=48.986486\times\text{second}[/tex]

[tex]\text{Time}\approx 49\text{ seconds}[/tex]

Therefore, it will take approximately 49 seconds for the elevator to travel from the ground floor to the roof.

(8,15) is the answer

It's not zero. Zero can only be produced in adding or subtracting when two equal numbers with opposite signs are added or subtracted. -4 + 4 would give 0.  Really tricky things like - 5 - (- 5) would be 0 because the 2 minus signs would give a plus.

-5 + 5 = 0

It's not positive either. Think money. If you owe someone 5 dollars and you put another 6 dollars on a credit card, your net worth isn't going up into the positive. It going down further into the negative. You wouldn't be alone. The US government does this every day. -5 - 6 = - 11

So  - 1/3 - 4/5 is  negative.

Buehlermaci,

The answer is option A "scarcity." It's not option B because economics is the distribution or a production of a item. It's not option C because opportunity cost is when you are looking at the value of two things before you make a decision on which you want kinda like pros and cons. Scarcity is the shortage on a resource but the person decides to spend it on wants and needs so basically the difference between limited resources and wants and needs.

length is nine inches less than twice width.    L = 2W - 9

perimeter is 84 inches                                   2L +2W = 84

Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing

2(2W-9) + 2W = 84

4W - 18 + 2W = 84

(4W+2W) = 84+18  

6W =  102

W = 102/6 = 51/3

L = 2(51/3) - 9

= L= 17-9
