Kim is drawing a map of the different schools in her school district.she knows that her middle school is 10.6 miles away from the middle school that her best friend attends.if every 2 inches on the map represents 5 miles, how far apart will the two schools be on the map,to the nearest tenth of an inch

Answers

so Kim and her best friends are 10.6 miles away and we are trying to find out how many inches are they apart

10.6/5 = 2.12 
that equation represents how many miles away they are now we mulitply 
2.12x 2 to find a number of inches 4.24

Answer:

4.24 inches.

Step-by-step explanation:

In the map,

2 inches represents 5 miles,

Thus, we can write,

[tex]5\text{ miles}=2\text{ inches}[/tex]

[tex]1\text{ mile}=\frac{2}{5}\text{ inches}-----(1)[/tex]

Since, the actual distance between the two schools is 10.6 miles.

Multiplying both sides by 10.6 in equation (1),

[tex]10.6\text{ miles}=10.6\times \frac{2}{5}=\frac{21.2}{5}=4.24\text{ inches}[/tex]

Hence, the distance between the two schools in the map is 4.24 inches.

What are the solutions to the inequality? Graph the solutions. x/5 greater than or equal to -2

Answers

x/5 > -2

">" is the greater than sign, and ">" means it is greater than or equal to since it is underlined. All you have to do now is put the inequality into slope-intercept form (y = mx + b) and plot the line on a graph.

In this inequality, -2 is y and x/5 is x. Just rearrange the terms while still keeping the answer the same.

x/5 > -2
-2 < x/5 Notice that the sign changed to "less than or equal to." This is because x/5 is still greater than or equal to -2, which makes -2 less than or equal to x/5.

Since it is "or equal to," we can discover what x could be by multiplying -2 by 5, which is -10. So the non-dotted line goes over the point -10 on the x-axis, straightly vertical without a slope, and everything that is greater than -10 is shaded, which is everything on the right side of the line. It should look like the attachment below.

What is the Percentage?

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Price of scented pencils = $7

Price of pencils after-tax = $7.49

Then, the percentage of tax on the pencils will be,

= (7.49 - 7)/7 × 100

= 0.07 × 100

= 7%

Describe the cross section

Answers

Answer:

D. Square

Step-by-step explanation:

A cross section is the shape that we get when we cut the object.

Here the given object is a cube.

It is cut straight through the middle.

Imagine a cube cut through the middle, when we look at the same on the top, we get square.

Since in a cube all the sides are equal.

Therefore, we get square when we cut the cube straight through the middle.

Answer: D. Square.

The cross-section of the shape in the image is a square.

Here's why:

The shape in the image is a cube.

A cube has six square faces.

When you cut a cube through the middle along any of its axes, the resulting cross-section will always be a square.

Therefore, the answer is D. square.

In triangle ΔABC, ∠C is a right angle and CD is the height to AB, Find the angles in ΔCBD and ΔCAD if: m∠A = α

m∠DBC =
m∠DCB =
m∠CDB =
m∠ACD =
m∠ADC =

Answers

Refer to the figure shown below.

Given:
m∠C = 90°, because ∠C is a right angle.
m∠D = 90°, because CD is the height to AB.
m∠A = α

Because the sum of angles in a triangle is 180°, therefore
m∠DBC + 90° + α = 180°
m∠DBC = 90° - α

Again, for the same reason,
m∠DCB + m∠DBC + 90° = 180°
m∠DCB + 90° - α + 90° = 180°
m∠DCB = α

For the same reason,
m∠ACD + 90° + α = 180°
m∠ACD = 90° - α

m∠ADC = 90° (by definition)
m∠CDB = 90° (by definition)

Answer:
m∠DBC = 90° - α
m∠DCB = α
m∠CDB = 90°
m∠ACD = 90° - α
m∠ADC = 90°

Maria gathered the data in the table. She finds the line of best fit to be y = 2.78x – 4.4. What is the residual value when x = 4?

Answers

The correct answer would be C.0.58

You plug 4 into the line of best fit and get 6.72. This is your predicted value, but the residual is the difference between the actual value and predicted. So you subtract: 7.3-6.72=0.58.

Solution:

The line of best fit is given as y=2.78x-4.4

We need to find the residual value when x=4.

The residual value is  an estimate of the wholesale value .To find the residual value we plug in x=4 in the given line of best fit.The corresponding y value will give the predicted  value.

y=2.78x-4.4

Substituting x=4,

y=2.78(4)-4.4

y=11.12-4

y=7.12.

The predicted value when x=4 is y=7.12.

Residual value = predicted value  - Actual value -=7.12 - actual value.

Graph f(x)=34x+2. Use the line tool and select two points to graph the line.

Answers

we have

[tex]f(x)=\frac{3}{4}x+2[/tex]

To graph the linear equation find the intercepts

we know that

The x-intercept is the value of x when the value of the function is equal to zero

The y-intercept is the value of the function when the value of x is equal to zero

so  

Find the y-intercept

for [tex]x=0[/tex]

[tex]f(x)=\frac{3}{4}*0+2=2[/tex]

the y-intercept is the point [tex](0,2)[/tex]

Find the x-intercept

Identify the 35th term of an arithmetic sequence when a1 = −7 and a 18 = 95

Answers

The solution is on the photo.

Please help me. Thank you.

Answers

1 is 80 because:
3m + 20 + 5m = 180
8m + 20 = 180 
8m = 160 
m = 20
Then 3(20) +20 = 80 because of vertical angles. 

The second one is 15 because of vertical angles. 2*115 = 230. 50*50 = 100. Add these up and you get 330. This leaves 30 missing degrees among the two remaining angles. Since the two remaining angles are congruent because they are vertical, you can divide 30 by 2 to get 15.

Answer:

Width of the compass should be more than the smallest space between P and RS, so that it cuts RS at two distinct points. Therefore, it must be wide enough so that the arc intersects RS←→ in two points. The photo is attached so that you can understand it more.

Which expression is equivalent to square root of 9x^2?

Answers

Let's take the square root of this

√(9x^2)

To make this easier, let's use the following property of roots.

√(ab) = √(a) * √(b)

Let's separate the square root into two different square roots.

√(9x^2)
= √(9) * √(x^2)

Now, let's solve for each square root individually.

√(9) = 3
√(x^2) = x

Now, combine them

3 * x = 3x

3x is your answer.

Have an awesome day! :)
9x^2 can be rewritten as 9*x*x or 3*3*x*x
You can think of 3*3*x*x as 3x*3x which is (3x)^2.

Now we can take the square root of (3x)^2 (which equals 9x^2).

√(3x)^2
The √ and the ^2 cancel out so you are left with 3x.

So, √9x^2 = √(3x)^2 = 3x.

3x is your answer!
