2 5/8 divided by 3/7

Answer:

40.2

Step-by-step explanation:

Side 1= x

Side 2= x+20

Side 3= x+40

Side 4= x+60

Side 5= x+80

Total perimeter= 401

x+x+20+x+40+x+60+x+80= 401

Simplify it...

5x=201

x= 40.2

This is the answer= 40.2

The length of the shortest side of the pentagon would be:

40.2

Given that,

Every side of a pentagon is longer by 20 inches.

No. of sides in pentagon = 5

So,

Ist side of the pentagon [tex]= x[/tex]

IInd Side of the pentagon [tex]= x + 20[/tex]

IIIrd Side of the pentagon [tex]= x + 40[/tex]

IVth Side of the pentagon [tex]= x + 60[/tex]

Vth Side of the pentagon [tex]= x + 80[/tex]

We know that,

Perimeter = Sum of all the sides

Since the perimeter is 401 inches, the side can be determined through:

[tex]401 = x+x+20+x+40+x+60+x+80[/tex]

⇒ [tex]401 = 5x + 200[/tex]

⇒ [tex]401 - 200 = 5x[/tex]

⇒ [tex]201/5 = x[/tex]

∵ [tex]x = 40.2[/tex]

Thus, 40.2 is the correct answer.

Answer:

  sometimes

Step-by-step explanation:

For positive numbers, multiplying by a factor greater than 1 increases their value:

  (1/2) × 2 = 1 > 1/2

For negative numbers, multiplying by a factor greater than 1 decreases their value:

  (-1//2) × 2 = -1 < -1/2

So, "sometimes" the product will be less than the given fraction.

Answer:

Rational because it's a whole number

Answer:

Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots. are given by the quadratic formula.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

Slope = m  & y-intercept = b

x - 5y = 15

   -5y = -x + 15

      y = [tex]\frac{-1}{-5}x + \frac{15}{-5}\\\\[/tex]

[tex]y = \frac{1}{5}x - 3[/tex]

so, slope = 1/5   ; (-5 , 7)

y -y1 = m(x -x1)

[tex]y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8[/tex]

It would be easier if you use a website with a graph! There is a website called "desmos" and if you search up desmos graphing calculator you will find it. Type in the points in the website, and it would add in the points for you.

but here is a piece of key information:

Make [tex]\frac{3}{4}[/tex] into a decimal. That would be 0.75.

Since it says "of the way from", count the boxes in the graph from each point.

The total cost of materials can be found from a list of materials based on the market unit rate.

The correct responses are;

Reasons:

Part A: The given expression representing the purchase is presented as follows;

Purchases = 180·s + 9·p + 36·l

Where;

s = Screws

P = Posts

l = Lumber

The factored expression is found as follows;

Purchases = 180·s + 9·p + 36·l = 9 × 20·s + 9·p + 9 × 4·l, which gives;

180·s + 9·p + 36·l = 9 × (20·s + p + 4·l)

The factored expression is; 9 × (20·s + p + 4·l)

Part B: The costs are;

100 screws  = $6.99

1 posts = $16.40

10 pieces of lumber = $88.20

The materials Roberto need to buy are;

180 screws, which can be obtained by buying 2 cartons of screws.

9 posts, which is obtained by buying 9 pieces of posts.

36 lumber which can be obtained by buying 4 × 10 pieces = 40 pieces of lumber.

Therefore, the, material Roberto needs to buy are;

2 cartons of screws

9 pieces of posts

40 pieces of lumber

Part C: The total cost of the materials are therefore;

2 cartons of screws × $6.99 per carton = $13.98

9 pieces of posts × $16.40 per piece = $147.6

4 Sets of 10 pieces of lumber × $88.20 per set = $352.8

The total cost = $13.98 + $147.6 + $352.8 = $514.38

H0 : π ≥ 0.92

H1 : π < 0.92

At α = 0.05

Left tail

Z0.05/2 = Z0.025 = - 1.645

The test statistic

Zstatistic :

(m - p) / σ

Sample size, n = 85

m = 74/85 = 0.87

p = 0.92

σ = sqrt(p(1 - p) /n)

σ = sqrt(0.92(1 - 0.92) / 85)

σ = sqrt(0.0008658)

σ = 0.0294258

σ = 0.0294

Zstatistic :

(m - p) / σ

(0.87 - 0.92) / 0.0294

Zstatistic = −1.700680

Zstatistic = - 1.70

Decision region :

Reject H0: if ;

Zstatistic < Zcritical

-1.70 < - 1.645

Since,

Zstatistic < Zcritical ; then Reject H0.

Answer:

-30n+42

Step-by-step explanation:

You have to use distributive property.

Multiply 6 with -5n which is -30n. Then, Multiply 6 with 7 which is 42. Since, 5n is negative the product is also negative, and since 7 is positive the product is positive. Therefore you will get, -30n+42.

I hope this helps!

Could I get brainliest? ✨

The simplified form of 6(-5n + 7) is -30n + 42.

To simplify the expression 6(-5n + 7), we apply the distributive property. The distributive property states that when we multiply a number outside the parentheses by an expression inside the parentheses, we must multiply it by each term inside the parentheses.

In this case, we have 6 multiplied by the expression (-5n + 7).

Multiplying 6 by -5n gives us -30n, and multiplying 6 by 7 gives us 42.

So, combining these results, we get -30n + 42.

This simplified expression, -30n + 42, cannot be further simplified because there are no like terms to combine.

Therefore, 6(-5n + 7) simplifies to -30n + 42.
