Answer:

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

Step-by-step explanation:

1. There are: 6+4 = 10 boys in the class ->  corresponding to 100 %

1 boy is corresponding to 100% :10 = 10%

6 in 10 have school dinners -> 10% x 6 = 60%

2. There are 10( boys) + 7 (girls) + 3 (girls) = 20 pupils in the class -> corresponding to 100%

1 pupil is corresponding to 100% : 20 = 5%

There are : 6 + 7 = 13 pupils who have school dinners

13 in 20 have school dinners -> 5% x 13 = 65%

The solution is :

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

Boys who have school dinners 6 boys who don't 4

Girls who have school dinners 7 girls who don't 3

so, we get,

1. There are: 6+4 = 10 boys in the class ->  corresponding to 100 %

1 boy is corresponding to 100% :10 = 10%

6 in 10 have school dinners -> 10% x 6 = 60%

2. There are 10( boys) + 7 (girls) + 3 (girls) = 20 pupils in the class -> corresponding to 100%

1 pupil is corresponding to 100% : 20 = 5%

There are : 6 + 7 = 13 pupils who have school dinners

13 in 20 have school dinners -> 5% x 13 = 65%

Hence, The solution is :

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

Answer:

The volume of the cone is less than the volume of the cylinder .

Cone volume is 1/3 the volume of cylinder volume

Step-by-step explanation:

We can see from the volume formulas:

for cone volume V = (1/3)*(pi)*(r^2)*h

for cylinder volume C = (pi)*(r^2)*h

for equal base and height,  C = 3*V

The volume of the cone is less than the volume of the cylinder .

Cone volume is 1/3 the volume of cylinder volume

The correct answers are:

A) The volume of the cone is 1/3 the volume of the cylinder.

C) The volume of the cone is less than the volume of the cylinder.

 D) The expression 84(pi)/3 finds the volume of the cone.

Answer:

after 10 seconds  the charge  is 1.624

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one.

The electrical charge on a metal plate is given  by the function below, where t is the time in  seconds. What is the charge after 10 seconds?

C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]

My answer:

Given the information:

C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]  

when t =10 we have:

C (10) = 12[tex]e^{\frac{-10}{5} }[/tex]

<=>  C (10) = 12[tex]e^{-2}[/tex]

<=>  C (10) = 12[tex]\frac{1}{e^{2} }[/tex]

<=> C (10) = 12 * 0.1353

<=>  C (10) = 1.624

Hence, after 10 seconds  the charge  is 1.624

Answer:

C

Step-by-step explanation:

The T shape is composed of 2 rectangles.

Area of top rectangle = 20 × 4 = 80 cm²

Area of upright triangle = 16 × 6 = 96 cm²

Total area = 80 + 96 = 176 cm² → C

Answer:

82.5cm²

Step-by-step explanation:

The volume of a triangular prism is : V = 1/2 * a * c * h

V = 1/2 * 3 * 5 * 11

= 165/2

Answer:

[tex]f(x)=40*2^x[/tex]

Step-by-step explanation:

Mr Samuel Planted 40 pepper plants in 2005.

Therefore:

f(0)=40

Each year the number of pepper plants doubled.

In 2006, f(1)=40*2

In 2007, f(2)=40*2*2[tex]=40*2^2[/tex]

In 2008, f(3)=40*2*2*2[tex]=40*2^3[/tex]

If we continue in like manner. The number of pepper plants after x years will be given by the exponential function:

[tex]f(x)=40*2^x[/tex]

where 40 is the initial number and 2 is the growth factor.

Answer:

942 cm³.

Step-by-step explanation:

To find the volume of the cone, we will need to use the formula: [tex]\frac{1}{3}[/tex]bh.

To find the base, we simply need to find the area of the circle. This is done by using: [tex]\pi r[/tex]².

From this, we get a base area of ≈314 cm².

Now, to find the volume of the cone, we, multiply by the height giving us:

314×9= 2826.

Finally, the last step is to multiply this by [tex]\frac{1}{3}[/tex], resulting in:

2826×[tex]\frac{1}{3}[/tex]= 942.

Therefore,  942 cm³ is the correct answer.

Answer:

Equations: [tex]x+y=80\,,\,2x+4y=216\,\,[/tex]

number of chickens = 52

number of goats = 28

Step-by-step explanation:

Given: A small ranch has chickens and goats

Total number of heads = 80

Total number of legs = 216

To find: number of chickens and goats

To draw: the graph

Solution:

Let x denotes number of chickens and y denotes number of goats.

According to the question,

[tex]x+y=80\,\,(i)\\2x+4y=216\,\,(ii)[/tex]

From (i), put [tex]x=80-y[/tex] in (ii)

[tex]2(80-y)+4y=216\\160-2y+4y=216\\2y=216-180\\2y=56\\y=\frac{56}{2}=28[/tex]

Put [tex]y=28[/tex] in equation (i)

[tex]x+28=80\\x=80-28=52[/tex]

So,

number of chickens = 52

number of goats = 28

Answer: $786

Step-by-step explanation:

first hour = $50

Second hour = $60

Third hour = $72

Total amount after 24 hours :

4th hour = 72 + 1 4 = 86

5th = 86 + 16 = 102

6th = 102 + 18 = 120

7 = 120 + 20 = 140

8 = 140 + 22 = 162

9 = 162 + 24 = 186

10 = 186 + 26 = 212

11 = 212 + 28 = 240

12 = 240 + 30 = 270

13 = 270 + 32 = 302

14 = 302 + 34 = 336

15 = 336 + 36 = 372

16 = 372 + 38 = 410

17 = 410 + 40 = 450

18 = 450 + 42 = 492

19 = 492 + 44 = 536

20 = 536 + 46 = 582

21 = 582 + 48 = 630

22 = 630 + 50 = 680

23 = 680 + 52 = 732

24 = 732 + 54 = 786

Using the Triangle Inequality Theorem, we can conclude that the pieces of wood measuring 2ft, 3ft, 4ft, and 3ft, 4ft, 5ft can be used to build a triangle-shaped garden.

To determine which pieces of wood can be used to build a triangle-shaped garden, we need to apply the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. We will check each set of wood pieces to see if they fit this criterion.

Therefore, the pieces of wood that can be used to build a triangle-shaped garden are the ones measuring 2ft, 3ft, 4ft and 3ft, 4ft, 5ft.

To determine the weight for each animal and their total combined weight, you would need to know the weight of each individual animal. Let's say we have three animals: a lion weighing 200 pounds, a zebra weighing 300 pounds, and a giraffe weighing 500 pounds. To find their total combined weight, you simply add up their weights: 200 + 300 + 500 = 1000 pounds.

Answer:

116.31468544 mg ibuprofen left

Step-by-step explanation:

Since there are 800 mg at the beginning and the system decreases by about 32% of the ibuprofen

After 1 hour

→ 800 - (800x32/100) = 800 - 256 = 544 mg ibuprofen left

After 2 hours

→ 544 - (544x32/100) = 544 - 174.08 = 369.92 mg ibuprofen left

After 3 hours

→ 369.92 - (369.92x32/100) = 369.92 - 118.3744 = 251.5456 mg ibuprofen left

After 4 hours

→ 251.5456 - (251.5456x32/100) = 251.5456 - 80.494592 = 171.051008 mg ibuprofen left

After 5 hours

→ 171.051008 - (171.051008x32/100) = 171.051008 - 54.73632256 = 116.31468544 mg ibuprofen left

To find the amount of ibuprofen left after 5 hours, the initial 800 mg is multiplied by 0.68 raised to the 5th power, resulting in approximately 115.28 mg remaining.

To calculate the amount of ibuprofen left after 5 hours, we can use the exponential decay formula. Since the amount decreases by 32% each hour, we can represent this as a decay rate of 68% (100% - 32%) remaining each hour. Therefore, the amount of ibuprofen after one hour is 68% of the initial amount, and we can represent this as a multiplication by 0.68 for each passing hour.

The formula to find the amount of ibuprofen left after 5 hours is:

Final amount = initial amount × (0.68)⁵

Using the initial amount of 800 mg and raising 0.68 to the 5th power:

Final amount = 800 mg × 0.68⁵

Final amount = 800 mg × 0.1441

Final amount ≈ 115.28 mg

So, approximately 115.28 mg of ibuprofen is left in the adult's system after 5 hours.

Answer:

0.8415 :)

Step-by-step explanation:

To find the product of 5.61 and 0.15, multiply the two numbers to get 2805 and then place the decimal to account for a total of four decimal places in both numbers, resulting in a product of 0.8415.

The product of 5.61 and 0.15 is calculated by simply multiplying the two numbers together. To do this, you can line up the numbers as you would in any multiplication problem, making sure to pay attention to the decimal places:

Since there are two decimal places in each number we are multiplying (two in 5.61 and two in 0.15), we need to have a total of four decimal places in the answer. Taking the raw multiplication result of 2805 and inserting the decimal correctly, we get the final answer:

Therefore, the product of 5.61 and 0.15 is 0.8415.
