Answer:

65; 117; 143.

Step-by-step explanation:

1. if the ratio is 5/9/11 and the perimeter is a+b+c=325, then it is possible to write (for the perimeter):

5x+9x+11x=325;

2. to calculate the value of 'x':

x=13;

3. the required sides are:

5x=65; 9x=117; 11x=143.

Answer: (x-4) is not a factor of the given polynomial.

===================================================

Explanation:

Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).

In this case, we have k = 4 and we can find that:

p(x) = 2x^4-9x^3-20x^2+147x-180

p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180

p(4) = 24

The result we get is not zero, so that means (x-4) is not a factor of p(x).

Answer:

13 quarters, 26 nickels.

Step-by-step explanation:

n will be number of nickels, q will be number of quarters, and we have 39 total coins

so n + q = 39 (number of nickels + number of quarters = 39 coins.

The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)

which means

n + q = 39

2q + q = 39

3q = 39

q = 13

and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels

LMK if you have questions.

If you want to double check the money,

n(0.05) + q(0.25) = 4.55 is the equation to use.

26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55

Answer:

29.4

Step-by-step explanation:

42+34=76

76+31=107

107+30+30=167

167+29=196

196+28=224

224+27=251

251+24=275

275+19=294

there are 10 cars that he wants

294/10=29.4

The median of the given data set is 29.5.

Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.

For example;

Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.

As per the given mileage set,

34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.

Write the above set in increasing order as

19,24,27,28,29,30,30,31,34,42

The median will be the middle value, since there is an even number so median will be as,

Median = (5th value + 6th value)/2

Median = (29 + 30)/2 = 29.5

Hence "The median of the given data set is 29.5".

Answer: its 3x+20 to my calculations

Step-by-step explanation:

Answer:

7.21 units

Step-by-step explanation:

GIven data

Point 1= (8,3)

x1= 8

y1= 3

Point 2=  (2,7)​

x2= 2

y2= 7

The expression for the distance between two points is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((2-8)²+(7-3)²)

d=√((-6)²+(4)²)

d=√36+16

d=√52

d= 7.21

Hence the distance between the points is 7.21 units

Answer:

Talking 65 minutes, $ 6.50 must be paid.

Step-by-step explanation:

Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:

0.10 x M = A

0.10 x 65 = A

6.50 = A

Thus, talking 65 minutes, $ 6.50 must be paid.

Answer:

The second table, counting from the top.

X      Y

2      0

4       2

6       4

Step-by-step explanation:

A proportional relationship is written as:

y = k*x

where k is called the constant of proportionality, is a real number different than zero.

Here we have different tables, if for two pairs (x, y) of the table we have the same value of k, then the relation is proportional. Also you can see that if x = 0, we have:

y = k*0 = 0

then a proportional relationship always has the point (0, 0)

A)

X       Y

1        6

2       12

3       18

Let's use the first two pairs:

(1, 6)

6 = k*1

6/1 = k = 6

(2, 12)

12 = k*2

12/2 = k = 6

in both cases we have k = 6, then this is a proportional relationship.

B)

X      Y

2      0

4       2

6       4

Here we can see the pair (2, 0)

This means that when x = 2, we have y = 0

Then this can not be a proportional relationship, because:

0 = k*2

k = 0

This is not a proportional relationship.

C)

X    Y

1     2

2    4

3    6

Let's find k for the first two points.

(1, 2)

2 = k*1

2/1 = k = 2

(2, 4)

4 = k*2

4/2 = k = 2

In both cases we have k = 2, then this is a proportional relationship.

D)

X   Y

2   -4

4   -8

6   -12

Let's find k for the first two points:

(2, -4)

-4 = k*2

-4/2 = k = -2

(4, -8)

-8 = k*4

-8/4 = k = -2

In both cases we have k = -2, then this is a proportional relationship.

Answer:

Step-by-step explanation:

n-(7+n) which is a strange problem to give you as that is equal to

n-7-n which always equals -7

And that means n can be any real number and the expression still equals -7

The algebraic expression will be -7. x is the assumed algebraic expression. The equation is solved by subtraction.

An algebraic expression is a phrase that has been combined using operations like addition.

Let n is the number and x be the solution for the given condition;

If the number is decreased by 7 then the equitation will be (n-7).

From the given condition;

[tex]\rm x=\rm n-(n-7) \\\\ x=n-n-7 \\\\ x=-7[/tex]

Hence the algebraic expression will be -7.
