weight of Lily's stamp collection is 19.8 grams, about how many
stamps are in Lily's stamp collection?

Answer:

2

Step-by-step explanation:

no. of apples with John= 2

no. of apple Sandy got= 1

so, no. of apple remaining with John= 2-1= 1

therefore,

altogether = 1+ 1 = 2.

hence, they have 2 apples altogether

Answer:

2

John have 2 apples and he gave 1 apple to sandy , John have 1 apple left and sandy also have 1 apple so 1+1 =2

19 - 2 = 17

Answer:

17

Step-by-step explanation:

half of 48 is 24

24 divided by 6 is 4

4× 4= 16

Remark

This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2

Equations

l^2 + r^2 = l^2

l is the slant height.

Solution

SA = π * l * r + π r² = π(1 + √5)          Divide both sides by π

Find l

l * r + r^2 = 1 + √5

l^2 = r^2  + h^2

l^2 = r^2 + (2r)^2

l^2 = 5r^2

l = √5 * r

Now go back to this equation to find r

l * r + r^2 = 1 + √5                               Substitute the value for l

√5 r * r + r^2 = 1 + √5                         On the left pull out r^2

r^2 (1 + √5) = 1 + √5                            Divide by 1 + √5

r^2 = 1                                                  Take the square root on both sides

sqrt(r^2) = sqrt(1)

r =1

Therefore h = 2

Volume of the cone.

V = 1/3 * π r² h

V = 1/3 * π 1² 2

V = 2/3 * pi

Unitary cost per card= $0.21

Step-by-step explanation:

Giving the following information:

Number of cards per packecge= 25

Total cost per package= $5.25

To calculate the unitary cost of each card, we need to use the following formula:

Unitary cost per card= total cost / number of cards per package

Unitary cost per card= 5.25 / 25

Unitary cost per card= $0.21

Answer:

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6[/tex]

Step-by-step explanation:

Rationalizing the Denominator

Rationalizing the denominator means to get rid of any radicals in the denominator.

We use the conjugate of the denominator to rationalize. The conjugate of a binomial is obtained by changing the sign that is between the two terms while keeping the same order of the terms. For example, the conjugate of

[tex]\sqrt{7}-2[/tex] is [tex]\sqrt{7}+2[/tex].

We need to use the algebraic identity:

[tex](a-b)(a+b)=a^2-b^2[/tex]

Let's rationalize

[tex]\displaystyle \frac{9}{\sqrt{7}-2}[/tex]

Multiply numerator and denominator by the conjugate of the denominator:

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9}{\sqrt{7}-2}\cdot\frac{\sqrt{7}+2}{\sqrt{7}+2}[/tex]

Operate in the numerator and apply the identity in the denominator

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9(\sqrt{7}+2)}{(\sqrt{7}-2)(\sqrt{7}+2)}[/tex]

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{(\sqrt{7})^2-2^2}[/tex]

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{7-4}=\frac{9\sqrt{7}+18}{3}[/tex]

Dividing:

[tex]\boxed{\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6}[/tex]

Answer:

Step-by-step explanation:

The statement supported the graph is

The axis of symmetry is x = 3

The coordinates of the y-intercept are (0,7)

A line that divides an object into two equal halves and produces a mirror-like reflection of each side of the object is known as an axis of symmetry.

1. The axis of symmetry is x = 3

The axis of symmetry is the central axis of the graph, which signifies the middle point of the graph. It is evident that this graph is centered on x = 3.

2. The coordinates of the y-intercept are (0,7)

The y intercept is the point where the graph meets the y-axis, that is, the value of y on the graph when x=0.

From the graph, the coordinates of the y-intercept is (0, 7)

3. The X-intercept is located at (-3,0)

The x intercept is the point where the graph meets the x-axis, that is, the value of x on the graph when y=0.

From the graph the curve x axis at x= 1.5 and x= 4.5

So, the x-intercept is truly located at (1.5, 0) and (4.5,0)

Step-by-step explanation:

Just subtract 2.41 from 36.35 and you get the answer. Easy!

The simplified form of the given expression is 0.2x-1.5y.

The given expression is 4.2(2x-0.5y)-2(4.1x-0.3y).

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The given expression can be solved as follows

4.2(2x-0.5y)-2(4.1x-0.3y)

= 8.4x-2.1y-8.2x+0.6y

=  8.4x- 8.2x-2.1y+0.6y

= 0.2x-1.5y

Therefore, the simplified form of the given expression is 0.2x-1.5y.

Answer:

answer is 10/9

:-)))☺️☺️

I hope it helps you

Answer: 1 and 1/9

Step-by-step explanation: Here, we have 5/6 ÷ 3/4.

Dividing by a fraction is the same as multiplying by its reciprocal.

In other words, we can change the division

sign to multiplication and flip the second fraction.

So here, 5/6 ÷ 3/4 can be rewritten as 5/6 × 4/3.

Now we're simply multiplying fractions so we multiply across the

numerators and multiply across the denominators.

So we have 5 × 4 which is 20 and 6 × 3 which is 18.

Notice that 20/18 is not in lowest terms so we divide the

numerator and the denominator of 20/18 by 2 to get 10/9.

If you would like, you can change this to the mixed number 1 and 1/9

by simply dividing 9 into 10 and putting the remainder over the denominator.

Answer:

You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.

Step-by-step explanation:

Say you were multiplying 14.63 and 7.74

                   14.63

                   x 7.74                 Always starting from the right side of the equation

                   .5852                go to the left four digits and put a decimal then                  

                  ↑←←←←                just carry the decimal down and you'll  end up with  

                 10.2410              the final product
