Answer:

6.82 kg

Step-by-step explanation:

set up a proportion based on 2.2 lbs in 1 kg

2.2/1 = 15/x

cross-multiply:

2.2x = 15

x = 6.82

The value of 15 lb in kg is 6.81 kg.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We know that;

⇒ 1 lb = 0.454 kg

Hence, We get;

⇒ 1 lb = 0.454 kg

⇒ 15 lb = 15 × 0.454 kg

            = 6.81 kg

Thus, We get;

⇒ 15 lb = 6.81 kg

Step-by-step explanation:

Answer:  28 boys and 16 girls

Step-by-step explanation: Divide 44 by 2 to get 22 subtract 22 by 6 to get the girls and add 6 to 22 to get the boys.

Answer:

44% of the students of a class are girls. If the number of girls is 6 less than the number of boys, how many students are there in the class?

let x be the number of boys, so (x - 6) will be number of girls.

total number of students will be boys plus girls : x + (x - 6) = 2x - 6

now 44% are girls which come from formula no. of girls divide by total students into 100: (x - 6)/(2x-6)*100 = 44

by solving we get x = 28 (where x is number of boys)

now x - 6 = 28–6 = 22 (number of girls)

add both we get total number of students = 28 + 22 = 50

Answer = 50

Answer:

y = 2, x = -1

Step-by-step explanation:

2y - 5x = 9

2y = 9+5x

y = (9+5x) /2

4y + 3x = 5

4((9+5x) /2) + 3x = 5

13x + 18 = 5

13x = -13

x = -1

y = (9+5x) /2

y = (9+5(-1)) /2

y = 2

Answer:

x = -1, y = 2

Step-by-step explanation:

2y - 5x = 9

4y + 3x = 5

eliminate one of the variables by multiplying the equations and then adding them together.

3(2y - 5x = 9)

5(4y + 3x = 5)

6y - 15x = 27

20y + 15x = 25

26y = 52

y = 2

now input the value of y into one of the original equations to find x.

8 + 3x = 5

8-5 = 3

x = -1

Answer:

Proportion of the flowers that are red tulips = [tex]\frac{2.57}{11}[/tex]

Step-by-step explanation:

Given - There are some flowers in a shop.  Each flower is either red or

             yellow.  Each flower is either a tulip or a rose.  For these flowers

              number of tulips : number of roses = 6:5  and number of red tulips :    

             number of yellow tulips = 3:4

To find - Work out the proportion of the flowers that are red tulips.

Proof -

Let Total number of flowers in a shop = 11x

As given, number of tulips : number of roses = 6:5

⇒Total number of tulips in a shop = [tex]\frac{6}{11}.11x[/tex] = 6x

   Total number of roses in a shop = [tex]\frac{5}{11}.11x[/tex] = 5x

Now,

As given, number of red tulips : number of yellow tulips = 3:4

⇒Total number of red tulips = [tex]\frac{3}{7}.6x[/tex] = 2.57x

   Total number of yellow tulips = [tex]\frac{4}{7}.6x[/tex] = 3.43x

∴ we get

Proportion of the flowers that are red tulips = [tex]\frac{2.57x}{11x}[/tex] = [tex]\frac{2.57}{11}[/tex]

Slope and a point that is not an intercept

Let

x ----> the time in hours

y ----> the area (in square meters) left to paint

we know that

Hiro paint at a rate of 8 square meters per hour

The rate is equal to the slope of the linear equation

we have the point (3, 28) ---> After 3 hours of painting, he had 28 square meters left to paint.

Khan answer

Answer:

It is not possible because no number times itself can equal a negative number.

Answer:

Taking the square root of a negative number is a problem because this technically does not follow the rules of a square root. A square root is made of a number times itself, and therefore, is impossible to have a negative times a positive to make a negative total (An example would be √4, as the answer can be 2 (because 2 x 2 = 4) or -2 (because -2 x -2 = 4)).

This means that in order to solve √-4, you must use imaginary numbers. This is represented by "i."

For the example of √-4, your answer would be 2i. These imaginary numbers are used whenever you are square rooting a negative number in order to show that it is breaking the real rules of roots.

Answer:

$12,088

Step-by-step explanation:

Value = $28,000

Rate, r = 14% = 0.14

Time = 6 years

Using an exponential function :

A = Pe^-rt

P = initial value

A = final worth

A = 28000*e^-(0.14*6)

A = 28000 * e^-0.84

A = 28000 * 0.4317105

A = 12087.894

Worth after 6 years = $12,088

Step-by-step explanation:

The solution to an equation is the true value of the equation

So, Maria's solution is incorrect

The equation is given as:

[tex]-5n = -9[/tex]

And the solution is given as:

[tex]n = 1[/tex]

To determine if her solution is correct, then she needs to substitute her solution in the given equation.

In other words, substitute 1 for n in [tex]-5n = -9[/tex]

[tex]-5 \times 1 = -9[/tex]

Multiply -5 and 1

[tex]-5 = -9[/tex]

The above equation is false.

This is so, because -5 does not equal -9

i,e, [tex]-5 \ne -9[/tex]

Hence, Maria's solution is incorrect

Answer:

115 degrees

Step-by-step explanation:

We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.

Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees

Answer:

choice 3) W = 115 degrees

Step-by-step explanation:

all triangle interior angles add up to 180 degrees

180 = 45 + 70 + X

X = 65 degrees

Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)

W = 180 - 65 = 115 degrees
