Answer:

Ben can drive 500 miles for $ 80

Step-by-step explanation:

Let y be the cost of traveling and x be the number of miles . The charge is $20 plus the $0.12 per mile which means the cost $ 20 is constant and an additional cost of $ 0.12 is spent on every mile. Then according to the given conditions the equation will be

y = $20 + $ 0.12(x) where x is the number of miles

Now we can solve x for y= 80

$ 80= $20 + 0.12 (x)

$ 60 = 0.12x

x= 60/ 0.12= 500

Ben can drive 500 miles for $ 80

Answer:

x = 25

Step-by-step explanation:

The measure of angle A is 108°

An angle is formed when two straight lines or rays meet at a common endpoint.

Supplementary angles are those angles that sum up to 180 degrees.

Given that angle A and angle B are supplementary angle

∠A=(7x+10)°

∠B=(7x−26)°

(7x+10)° + (7x−26)° =180°

14x - 16° =180°

14x =196°

x= 14°

∠A=(7x+10)°

∠A=(7(14) +10)°

∠A= 108°

Thus the measure of angle A is 108°

Answer:

C

Step-by-step:

The answer is c because 7.6 & 8.2 are both rational numbers and it goes onto natural numbers. They are also ordered in the from least to greatest like on a number line, 7.6, 8.2, 50, 65, 78. Plus, I'm kinda on the same unit.

Answer: Hi!

Answers B and D are correct.

For B, since negative numbers are on the left side of the number line, a positive number would have to be to the right of a negative number. Since we are adding a negative and a positive number of the same absolute value (9), they would cancel out to 0, which makes D true.

Hope this helps!

Hi there! Hopefully this helps!

-----------------------------------------------------------------------------------------------------

Explanation for D: -9 + 9 = 0.

Explanation for B: Negative numbers are on the LEFT side of the number line.

And positive numbers are on the right.

Therefore, 9 is to the RIGHT of -9 on the numberline.

Answer:

They should be blocked by body fat composition so the subjects are as similar as possible.

Step-by-step explanation:

It's D .

Blocking here means how should the subjects be arranged in terms of body fat or weight.

Option A is wrong because alphabetically controlling body fat would not get desired results.

Option B is wrong because different age groups would yield different results.

Option C is wrong also because weight loss is not dependent on taller people.

Option D is correct because controlling body fat would yield best possible results in ascending or descending order

Option E is incorrect because  arranging data in ascending or descending order would simplify the researches experiments.

Answer:

X=0

Step-by-step explanation:

1.Remove the parentheses

3x + 5 = 2x + 2 -(x-3)  ->  3x+5=2x+2-x+3

2.Combine like terms

3x+5=2x+2-x+3 -> 3x+5=x+5

3.Cancel Equal Terms

3x+5=x+5 -> (subtract 5 from both sides)  3x=x

(subtract x from both sides) 3x=x ->  3x-x=0

4.Combine like terms

3x-x=0  ->  2x=0

5.Get rid 2 so divide both sides by 2

2x= 0 -> [tex]\frac{2x}{2}[/tex]=[tex]\frac{0}{2}[/tex]  ->

Answer:

n = 13

Step-by-step explanation:

7n + 5 = 96

Subtract 5 from both sides to get rid of the 5 on the right side:

7n + 5 - 5 = 96 - 5

7n = 91

Divide both sides by 7 to get rid of the coefficient of n:

7n / 7 = 91 / 7

n = 13

Answer: [tex]n=13[/tex]

Subtract 5 from both sides

[tex]7n+5-5=96-5\\7n=91[/tex]

Divide both sides by 7

[tex]7n/7=91/7\\x=13[/tex]

Hi

draw 1 :  4/12 = 1/3

draw2 :  3/11

draw 3 : 5/10 = 1/2

so probability to have  :  1 banana then 1 apple then 1 orange  is :  1/3*3/11*1/2 =  3/66 =  3*1 / 2*3*11 =  1/22

Answer:

1/22

Step-by-step explanation:

Work out the probability of selecting each fruit then times them together so

there are 12 fruits in total and 4 bananas so the chance of selecting a banana is 4/12 simplified 1/3

then as you dont put the banana back there is only 11 fruits left in the basket and 3 are apples so the chance of selecting an apple is 3/11

then as you dont put the apple back there is only 10 fruit left in the basket and 5 are oranges so the chance of selecting an orange is 5/10 simplified 1/2

then we multiply them all together 1/3 x 3/11 x 1/2 3/66 to get which simplifies to 1/22

Answer:

The answer is "Option A"

Step-by-step explanation:

The domain is the collection of the value, which belongs to the separate variable (horizontal axis). So, to find a region with a graph, it must search for the function, which starts and end. And at all these levels we are searching at x-values.  

Its starting point is (2,9) and the ending point is (8,3).  Therefore, x= 2 to x=8 is the domain.

Answer:

x = [tex]\frac{a(a + b)}{a-b}[/tex]

Step-by-step explanation:

Step 1: Write out formula

a(x - b) = a² + bx

Step 2: Distribute

ax - ab = a² + bx

Step 3: Add ab to both sides

ax = a² + bx + ab

Step 4: Subtract bx on both sides

ax - bx = a² + ab

Step 5: Factor

x(a - b) = a² + ab

Step 6: Divide (a - b) on both sides

x = [tex]\frac{a^{2} + ab}{a-b}[/tex]

Step 7: Factor

x = [tex]\frac{a(a + b)}{a-b}[/tex]

And we have our final answer!

Answer:

[tex] \boxed{ \bold{ \sf{Mean \: = 41.5}}}[/tex]

[tex] \boxed{ \bold{ \sf{Median = \: 41}}}[/tex]

Step-by-step explanation:

Given weights of the dogs :

38 , 40 , 42 , 46 , 45 , 39 , 42 , 40

Find the sum of the whole data:

sum of all items ( Σx ) = 38 + 40 + 42 + 46 + 45 + 39 + 42 + 40 = 332

Number of items ( n ) = 8

To find mean, divide the sum by the total number of data.

Finding the mean weights:

[tex] \boxed{ \sf{Mean = \: \frac{ Σx}{n}}} [/tex]

⇒[tex] \sf{ \frac{332}{8} }[/tex]

⇒[tex] \sf{41.5}[/tex]

Mean weights = 41.5

-----------------------------------------------------------------------

Finding the median

To find the median, arrange the given data in ascending order.

Given data : 38, 40 , 42 , 46 , 45 , 39 , 42 , 40

Arranging the data in ascending order :

38 , 39 , 40 , 40 , 42 , 42 , 45 , 46

Total number of observation ( n ) = 8

Finding the position of median

[tex] \boxed{ \sf{Position \: of \: median = ( \frac{n + 1}{2} ) ^{th} item}}[/tex]

⇒[tex] \sf{( \frac{8 + 1}{2} ) ^{th} item}[/tex]

⇒[tex] \sf{( \frac{9}{2} ) ^{th} item}[/tex]

⇒[tex] \sf{ {4.5}^{th} item}[/tex]

4.5 th item is the average of 4 th and 5th items .

Here, 4 th item = 40

5 th item = 42

Finding the median

[tex] \boxed{ \sf{Median = ( \frac{{4}^{th} \: item + {5}^{th} item}{2}) }}[/tex]

⇒[tex] \sf{ \frac{40 + 42}{2} }[/tex]

⇒[tex] \sf{ \frac{82}{2} }[/tex]

⇒[tex] \sf{41 }[/tex]

Hope I helped!
