Answer:

5.025 gallons

Step-by-step explanation:

Step 1: Convert 325 kilometers to miles

[tex]325 = 201[/tex]

Step 2: Set up a fraction

[tex]\frac{40}{1}=\frac{201}{x}[/tex]

Step 3: Cross multiply

[tex]40 \times x = 40\\\\201 \times 1 = 201[/tex]

Step 4: Divide the values left

[tex]201 \div 40\\\\= \frac{201}{40}\\\\= 5.025[/tex]

Therefore, about 5.025 gallons of gas will be used to go 325 kilometers.

Answer:

3m-83

Step-by-step explanation:

Okay, so first, you'd like to triple m. This would mean that it would be m+m+m, which is also 3m. Next you have to subtract 83. This would make it 3m-83.

Answer:

See solutions below

Step-by-step explanation:

For what values of X are the statements below true

A. 1x>x+1

x >x+1

x-x>1

0x > 1

x > 1/0

X >∞

B) |1-x|>3

The fucntion can both be positive and negative

For the negative function

-(1-x) > 3

-1+x > 3

x > 3+1

x > 4

For the positive function

1-x > 3

-x > 3 - 1

-x > 2

x < -2

Hence the required solutions are x > 4 and x < -2

c) For the equation

|x-15| < 0

-(x - 15) < 0

-x + 15 < 0

-x < -15

x > 15

Also x-15 < 0

x < 0+15

x < 15

Hence the required solution is x > 15 and x < 15

Step-by-step explanation:

equation for a parabola is:

The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus.

Given: focus= (3,-5), directrix at x =-7.

To find equation of parabola we will use distance formula,

√(x+7)²=√(x+3)² + (y+5)²

(x+7)²=(x+3)² + (y+5)²

x²+14x+49= x²+9+6x + (y+5)²

8x + 40 = (y+5)²

x= (y+5)²/8 -5

Hence, the equation of parabola is x= (y+5)²/8 -5

Answer:

We can conclude that the result is significant and production differ in cost variance.

Step-by-step explanation:

Given :

n1 = 16

n2 = 16

s1² = 5.7

s2² = 2.8

α = 0.10

H0 : σ1² = σ2²

H1 : σ1² ≠ σ2²

The test statistic :

Ftest = s1² / s2² =

Ftest = 5.7 / 2.8

Ftest = 2.036

Using the Pvalue from Fratio calculator :

df numerator = 16 - 1 = 15

df denominator = 16 - 1 = 15

Pvalue(2.036, 15, 15) = 0.0898

Pvalue = 0.0898

Since the Pvalue is < α ; We can conclude that the result is significant and production differ in cost variance.

Answer:

D

Step-by-step explanation:

Seventeen less than p infers that the number is p minus 17. This number is then divided by 8, which requires us to put parenthesis in order to properly divide the number after doing p - 17

Please give brainliest thank you

[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]

The quotient when 17 less than p is divided by 8.

Well, let's first take 17 less than p. That'll be :-

[tex] \sf \: p - 17[/tex]

Note :- 'p' comes first as the question has the words - less than p.

Now, we have the remaining -> 'is divided by 8'.

The equation will become :-

[tex] \sf \:( p - 17) \div 8[/tex]

Note :- We have put the bracket because they have asked the quotient. To form a quotient you need 2 numbers - a divisor & a dividend. Hence, 2 numbers -> (p - 17) & 8.

So, Option D [tex]\boxed{\underline{\bf \: (p-17)÷8}}[/tex] is the correct answer.

Answer:

5n - 119

Step-by-step explanation:

First, we notice that the sequence is going up by 5, so we could rule out 2 answers: -5n - 109, and -5n -119 (They go by -5). Then all we have to find is the  constant, -119 or -109. Well we could rule out -109 because -114 is included in the sequence, and if we start by -109 and start counting up, we will never get to -114. So, the solution is 5n - 119

We have been given that - 114, -109, -104, -99. the explicit rule for the sequence is 5n - 119.

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n+1)d, ...

Its nth term is

[tex]T_n = a + (n-1)d[/tex]

(for all positive integer values of n)

And thus, the common difference is

[tex]T_{n+1} - T_n[/tex]

for all positive integer values of n

We have been given that

- 114, -109, -104, -99,

a = -114

[tex]T_n = a + (n-1)d[/tex]

T = -114 + (n - 1)5

T = 5n - 119

Answers:

Area = 78 cm^2

Perimeter = 42 cm

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

Explanation:

Refer to the diagram below.

I've added points and labels, along with the dashed lines to break up the figure into three rectangles. The points in blue are the corner points of the original figure. The red points help set up the dashed lines.

Along the very top, we have BC = 8 cm, which breaks down into BK = 6 and KC = 2. Opposite of side KC is GJ = 2. For any rectangle, the opposite sides are always the same length.

Side AB = 9 cm. The three vertical sides of CD, EF, and GH all must add to get 9 cm in total, since the right side is the same height as the left side. We are given that EF = 3 and GH = 3, which must mean CD = 3 as well.

Through similar logic, the sides BC = 8 and DE = 4 add to 8+4 = 12 cm total. This total distance across the top must match the total distance along the bottom; i.e. the bottom horizontal sides of AH and GF must add to 12 as well. We are given AH = 6, so GF = 6 also.

Recall earlier we found GJ = 2. If GF = 6, then that leads to JF = 4.

In other words, GJ+JF = 2+4 = 6 = GF.

All of this is visually shown in the diagram shown below.

Once you have the diagram set up as shown, it's fairly straight forward from here. Compute the area of each of the three smaller rectangles and then add up those smaller areas to get the overall area.

I'll work from left to right to find the areas:

The total area of the composite figure is therefore: 54+12+12 = 78 cm^2

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

The perimeter is the sum of all the external sides. We'll ignore the dashed lines as they are not exterior segments.

perimeter = sum of exterior sides

perimeter = AB+BC+CD+DE+EF+FG+GH+HA

perimeter = 9+8+3+4+3+6+3+6

perimeter = 42 cm

Answer:

[tex]x = 12.5[/tex] degrees

Step-by-step explanation:

Since lines a and b are parallel, we have that angles 3 and 5 are congruent, that is, they have the same measure.

We have that:

[tex]m<3 = 10x[/tex]

[tex]m<5 = 12x - 25[/tex]

Value of x:

Since they are congruent:

[tex]m<3 = m<5[/tex]

[tex]10x = 12x - 25[/tex]

[tex]-2x = -25[/tex]

[tex]2x = 25[/tex]

[tex]x = \frac{25}{2}[/tex]

[tex]x = 12.5[/tex] degrees
