If 10 ladybugs fly from the lettuce to the alfalfa, which 2 kinds of plants will have the same number of ladybugs? Choose 2 answers: Roses Lettuce Alfalfa Grape vine

### Answers

Answer:

1.) Roses ; 2.) Alfalfa

Step-by-step explanation:

Given the graph below :

1 fruit = 5 ladybugs

Initial number of ladybugs on the roses = (7*5) = 35 lady bugs

Subtracting 10 ladybugs from lettuce and adding to the Alfalfa ;

Total number of ladybugs on the Alfalfa = (25 + 10) = 35 ladybugs

Hence, both the Roses and Alfalfa now have the same number of ladybugs.

Lettuce has 5 and grape has 10 Ladybugs

Hence, number of ladybugs on the Roses and Alfalfa are the same.

### Answers

The ratio 4:3 means for every 4 girls there are 3 boys.

Divide total girls by 4, multiply that by 3 to get total boys:

180/4 = 45 x 3 = 135

There are 135 boys

For total students add boys and girls:

180 + 135 = 315 total students

Can someone help me please with this math homework!!!

### Answers

**Answer:**

**-2x + 3y = -19**

**Step-by-step explanation:**

y + 1 = 2/3(x-8)

multiply by 3 to get rid of the fraction

3(y + 1 = 2/3(x-8)

3y + 3 = 2(x-8)

simplify

3y + 3 = 2x - 16

3y - 2x = -19

**-2x + 3y = -19 **

A rectangle is 12 feet long and 5 feet wide. If the length of the rectangle is increased by 25% and the width is decreased by 20%, what is the change in the area of the rectangle?

A.

measurements of all angles

B.

measurements of any two angles

C.

measurement of one angle and length of one side

D.

lengths of any two sides

### Answers

**Answer:**

The area remains the same

**Step-by-step explanation:**

First find the area of the original rectangle

A = l*w = 12*5 = 60 ft^2

Increase the length by 25%

12 + 12*25% = 12 +12*.25= 12+3 = 15

Decrease the width by 20

5 -5*20% = 5-5*.2 = 5-1 = 4

The new area is

A = l*w = 15*4 = 60ft^2

By selling a printer at Rs 15000 and Rs 18000, some lass and some profit are happened respectively. If the loss is one forth of profit, find its cost price

### Answers

**Answer:**

Loss= x

profit=y

x=1/4y

4x=y

Let cost = c

c-x= 15000

c+4x=18000

c+4x-(c-x)=18000-15000

5x=3000

x=600

c-x=15000

c-600=15000

**c=15600**

c+4x=18000

c+2400=18000

**c=15600**

Cost= Rs15600

A school in Delhi has its own flag, which is rectangular and divided into 4 rows and 6 columns. The word ‘SCHOOL' is inscribed in the first row, ‘FLAG' in the fourth row, and a purple coloured rhombus is in the middle

### Answers

**The question is incomplete. The complete question is :**

A school in Delhi has its own flag, which is rectangular and divided into 4 rows and 6 columns. The word ‘SCHOOL’ is inscribed in the first row, ‘FLAG’ in the fourth row, and a purple colored rhombus is in the middle, as shown in the given figure.

Based on this picture of the school flag, answer the following questions:

(a) What fraction of the flag has the purple rhombus?

**Solution :**

From the figure, the total number of squares in the flag of 4 rows and 6 columns are : 4 x 6 = 24 blocks

The purple colored rhombus is made on the half of the 4 blocks.

i.e. [tex]$\frac{1}{2} \times 4 = 2\ \text{blocks}$[/tex]

Therefore, the fraction of the flag that has the purple rhombus is :

[tex]$=\frac{2}{24}$[/tex]

[tex]$=\frac{1}{12}$[/tex]

The value of a jewel in 2015 was $17500. The jewel was purchased in 2008, and its value appreciated 2.5%

each year. What was the initial value of the jewel when it was first bought? Round to two decimal places

### Answers

**Answer:**

**$14722.14**

**Step-by-step explanation:**

We are given that

In 2015

The value of jewel=$17500

Rate of appreciation, r=2.5%

We have to find the initial value of the jewel when it was first bought.

Time, n=7 years

**Final value=[tex]Initial\;value (r/100+1)^n[/tex]**

Using the formula

[tex]17500=Initial\;value(2.5/100+1)^7[/tex]

[tex]17500=Initial\;value(1.025)^7[/tex]

[tex]Initial\;value=\frac{17500}{(1.025)^7}[/tex]

Initial value=$14722.14

**Hence, the the initial value of the jewel when it was first bought=$14722.14**

→ She wants to bake 48 cupcakes.

We have to find,

The number of trays of cupcakes she will need to bake.

The formula we use,

→ No. of cupcakes ÷ One dozen

Then we can divide,

→ 48 ÷ 12

→ 4 trays

Thus, none of the option is correct.

The function g(x) = \frac{1}{2}\left| {x} \right|g(x)= 21 ∣x∣ is a transformation of the absolute value parent function. Which graph shows g(x)?

### Answers

Answer:

A

Step-by-step explanation:

From what we have , it is expected that the parent function is a v-shaped graph that starts from the origin

The expected equation parent function should be;

y = |x|

Now, moving on, the transformed function is 1/2 of the parent function

This shows a direct compression of the initial partner function

So, it is expected that the transformed function is more compressed compared to the initial parent function

so, the correct choice of answer here is first option

**The Answer is Graph D **

You can see the graph number on the top left corner of each multiple-choice graph.

[tex]3n^2(n^2+4n-5)-(2n^2-14n+3)[/tex]

**To find:**

The difference of the polynomials and classify it in terms of degree and number of terms.

**Solution:**

Consider the polynomial,

[tex]P(x)=3n^2(n^2+4n-5)-(2n^2-14n+3)[/tex]

On simplification, we get

[tex]P(x)=3n^4+12n^3-15n^2-2n^2+14n-3[/tex]

Students in Mrs. Burn's science class used scales to measure the mass, in grams, of a solid. The mass of

the solid was reported as 5.7 grams, 5.8 grams, 6.2 grams, 5.9 grams, and 6.0 grams. Of the following,

which measure would best estimate the true mass of the solid?

minimum

maximum

mode

mean

### Answers

**Answer:**

Mean

**Step-by-step explanation:**

Finding the **mean, or the average, **of the different weights that were measured, would best estimate the true mass of the solid.

This would find the **average mass, **which would be the most accurate estimate of the solid's actual mass.

Using the minimum, maximum, and mode will not take into account **the other weights** that were measured. This makes it much more inaccurate.

So, the correct answer is **Mean. **

What's the sum of the infinite geometric series where a1 = 240, and the common ratio is r = 1∕3 ?

### Answers

**Answer:**

360

**Step-by-step explanation:**

The formula for the sum of an infinite geometric series is a₁/(1-r), where a₁ represents the first value and r represents the ratio. We can plug in our values here to get

a₁/(1-r) = 240/(1-1/3)

= 240 / (2/3)

= (240/1) / (2/3)

= (240/1) * (3/2)

= 360
