Answer:

a) The Metra will go 90 miles in 6 hours

b) It will take Amtrak 8 hours to travel 160 miles.

Step-by-step explanation:

From the question,

Metra travels 30 miles in 2 hours

a) To determine how far the Metra will go in 6 hours,

Let how far the Metra will go in 6 hours be x

Then,

If Metra goes 30 miles in 2 hours

Then, Metra will go x miles in 6 hours

x = (30 × 6)/2 miles = 90 miles

Hence, the Metra will go 90 miles in 6 hours.

b) To determine how long it will take Amtrak to travel 160 miles,

Let how long it will take Amtrak to travel 160 miles be y

From the question,

Amtrak travels 80 miles in 4 hours

Now,

If Amtrak travels 80 miles in 4 hours

Then, Amtrak will travel 160 miles in y hours

y = (160 × 4)/80 hours = 8 hours

Hence, it will take Amtrak 8 hours to travel 160 miles.

Answer:

The original cost of the butter cup was $91.

Step-by-step explanation:

Let x be the original price of the kitten butter cup.

Since Susan pays five out of seven of the original cos plus a fee of $24, the total amount she paid is 5x/7 + 24.

Now, this total amount equal the $89 she paid for the kitten butter cup. So,

5x/7 + 24 = 89.

We now solve this equation to find the original cost of the kitten butter cup.

So,

5x/7 + 24 = 89

Collecting like terms, we have

5x/7 = 89 - 24

5x/7 = 65

multiplying both sides by 7, we have

5x = 65 × 7

dividing both sides by 5, we have

x = 65 × 7 ÷ 5

x = 91

So the original cost of the butter cup was $91.

Step-by-step explanation:

Answer: The perimeter of rectangle M'N'O'P' =54 cm

Step-by-step explanation:

When we dilated a figure , then the image is the similar figure them the original.

For similar figures,

[tex]\dfrac{\text{Area of original figure}}{\text{Area of image}}=\dfrac{(\text{perimeter of original figure})^2}{(\text{perimeter of image})^2}[/tex]

As per given, Rectangle MNOP has a perimeter of 18 cm and an area of 14 cm².

Area of M'N'O'P' =  126 cm²

then,

[tex]\dfrac{14}{126}=\dfrac{18^2}{(\text{(perimeter of M'N'O'P'})^2}\\\\\Rightarrow\ \text{(perimeter of M'N'O'P'})^2=\dfrac{324}{14}\times126\\\\\Rightarrow\ \text{(perimeter of M'N'O'P'})^2=2916\\\\\Rightarrow\ \text{perimeter of M'N'O'P'}=\sqrt{2916}=54[/tex]

Hence, the perimeter of rectangle M'N'O'P' =54 cm

Answer:

y=(x+1)^2-7

Step-by-step explanation:

y=x^2+2x-6=x^2+2x+1-7

y=(x^2+2*1*x+1^2)-7

y=(x+1)^2-7

vertex form equation is y=a(x-h)^2+k

of equation y=ax^2+by+c

so a is 1

h is -1 because (x+1)=(x-(-1))

k is -7

Answer:

$1.44

Step-by-step explanation:

$11.52 (divided by) 8 = $1.44

The cost of each candy necklace will be $1.44 per candy necklace.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Rosa spent $11.52 on 8 candy necklaces for each of her two friends.

Then the cost of each candy necklace will be given by dividing $11.52 by 8.

⇒ $11.52 / 8

⇒ $1.44 per candy necklace

The cost of each candy necklace will be $1.44 per candy necklace.

Answer:

Step-by-step explanation

Rate of change is the slope, [tex]\frac{Y}{X}[/tex]

The distance from our y values which are -1 and 5 is 6.

The distance from our x values which 4 and 7 is 3.

Since its [tex]\frac{Y}{X}[/tex] The 6 would be over the 3 as 6/3 which simplifies to 2 or 2/1.

Answer:

Suppose you want to frame a collage of pictures. You have a 9-ft strip of wood for the frame. What dimensions of the frame give you the maximum area for the collage? What is the maximum area?

A:

Perimeter = 2(L + W) 9 = 2(L+W) L+W = 4.5 L = 4.5-W Area = LW Area = (4.5-W)W A = 4.5W - W^2 You have a quadratic with a = -1 and b = 4.5 Maximum area occurs when W = -b/(2a) = 4.5/(2*-1) = 2.25  

Step-by-step explanation:

Dimension of the picture with 9ft strip of wood is

length = 2.25 ft  and width =2.25 ft

Given :

you want to frame a collage of picture with a 9ft strip of wood.

the perimeter of the frame is 9 ft

Perimeter of rectangle = 2(length +width )

Let 'l' be the length and 'w' be the width

[tex]Perimeter =2(l+w)\\9=2(l+w)\\Divide \; by \; 2\\l+w=4.5\\l=4.5-w[/tex]

Now we find the area

[tex]Area = length \cdot width \\Area= l \cdot w\\A= (4.5-w)(w)\\A=-w^2+4.5w[/tex]

Now we find out 'w' where area is maximum

[tex]w=-\frac{b}{2a} \\a=-1 and b=4.5\\w=-\frac{4.5}{2(-1)} =2.25[/tex]

Width =2.25 gives us maximum area

Now find out the length ,

[tex]Length = 4.5 -w\\w=2.25\\Length = 4.5-2.25=2.25[/tex]

Dimension of the picture is length = 2.25 ft  and width =2.25 ft

glenn has 2 times as many hats so, h2 and then he has 4 less so -4

Answer:

It would be the first, 2h-4

Step-by-step explanation:

H stands for hats

We don’t have the numbers to solve, which we don’t need for this problem. But if we were solving we would multiply the amount of hats Mia has by two (2h). It says Glenn has four less than that, so you would then subtract four from whatever 2h would equal.

Answer:

x = 5

Step-by-step explanation:

Given that y is inversely proportional to x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportion

To find k use the condition when y = 25 , x = 4 , then

25 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

100 = k

y = [tex]\frac{100}{x}[/tex] ← equation of proportion

When y = 20, then

20 = [tex]\frac{100}{x}[/tex] ( multiply both sides by x )

20x = 100 ( divide both sides by 20 )

x = 5
