Answer:

2/9 times

Step-by-step explanation:

This is because 2/5 divided by 9/10 = 10/45 which if we simplify it we get 2/9 so that's why 2/9 is the right answer.

What is the relationship between the ratios? 48/72 and 6/9 Drag and drop to complete the statement. The ratios are . proportiona

IrinaVladis [17]

Answer:

The Ratios are Proportional

Step-by-step explanation:

Let,

R1 = 48 / 72 ----- (1)

R2 = 6/9 ------ (2)

If we divide right hand side of above equation by 8, we get,

$R1 = (48/8) / (72/8)\\R1 = 6/9$

Therefore, it means that, in simplified form, both ratios are same and hence proportional.

R1 : R2 = 6/9 : 6/9

The school band sold cupcakes to raise money for new uniforms each of the 40 band members baked cupcakes to sell they either bak

Volgvan

This question is incomplete. Here is the complete question below:

The school band sold cupcakes to raise money for new uniforms. Each of the 40 band members baked cupcakes to sell. They either baked chocolate or vanilla cupcakes.

Each student baked 24 cupcakes.

Each cupcake was sold for $2.

All of the cupcakes were sold.

A total of $1,200 was earned from the vanilla cupcakes.

How much did the band earn from the chocolate cupcakes?

Answer: $720 was earned from the sale of chocolate cupcakes.

Step-by-step explanation:

Taking key points from the question:

*** 40 band members baked chocolate or vanilla cupcakes.

*** Each student baked 24 cupcakes

***Each cupcake was sold for $2

***All cupcakes were sold.

***$1200 was earned from the vanilla cupcakes.

Now, before we can determine how much was earned from y chocolate cupcakes sold, we must find out how many cupcakes were baked and later sold altogether.

Since a single studi baked 24 cupcakes and all members of the bani (numbering 40) baked cupcakes, then :

24 × 40 = 960 cupcakes.

Therefore 960 cupcu were baked altogether by the members of the band.

Again, since a single cupcake (irrespective of the flavour) was sold for $2, then:

$2 × 960 = $1920 was the total amount earned after selling all the cupcakes.

Then, if $1,200 was earned from the vanilla cupcakes, we can calculate the amount earned for selling chocolate cupcakes by subtracting the amount realized after selling all the baked vanilla cupcakes from the total amount earned after selling all cupcakes:

$1,920 - $1,200

= $720

Therefore $720 was earned after selling chocolate cupcakes.

Indicate the general rule for this sequence. Find a 1 and the common difference. a 4 = 18 a 7 = 9

Orlov [11]

If $d$ is the common difference in an arithmetic sequence, whose $n$ -th term is $a_n$ , then

$a_7=a_6+d$
$a_6=a_5+d$
$a_5=a_4+d$

$\implies a_7=a_4+3d$

We have

$9=18+3d\implies3d=-9\implies d=-3$

Answer:

No solution.

Step-by-step explanation:

y = -2x + 1

y = -2x + 3

y can't be equal to two different values at once.

A triangle has perimeter 38 cm.

IrinaVladis [17]

Answer:

62cm

Step-by-step explanation:

You were told the perimeter of the triangle is 38

but two sides are added to make a Pentagon. and that Pentagon is made up of a triangle and a square.

so if we find the side of the square, we can equally get the other two sides of the triangle.

hint: (because it's a square, we would be getting an isosceles triangle, meaning two sides are equal)

because one side of the pentagon added to the other two sides of the triangles gives us the perimeter of the triangle.

we first find the sides of the square with all sides equal by diving by 2

$\frac{48}{2} = 12$

the sides of the square making the perimeter of the square 12cm.

now we subtract 12 from the perimeter of the triangle 38

$38 - 12 = 26$

now that we have gotten one side we can get the other two by dividing the result by 2

$\frac{26}{2} = 13$

so the other two sides of the triangle are 13cm.

now since we have the sides of the square and the triangle, we can find the perimeter of the pentagon by adding.

all the sides of the triangle without the base which is also the top of the square.

so instead of adding 4 times of 12, we add 3 times of 12 and 2 times of 13.

3(12)+2(13) = 62

12 + 12 + 12 + 13 + 13 = 62cm
