Zane had 7 green marbles. Then he bought 7 bags of blue marbles. There were 7 marbles in
each bag. How many marbles does Zane have now?

Answer:

y = 1/2x + 1

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.

Answer:

9.75

Step-by-step explanation:

3..25 x 3 =9.75

Step-by-step explanation:

First, you'd get the area of the circle, then multiply it by two (there's two ends to a cylinder)

so (pi)(R^2)

If 8 is the diameter, then 4 is the radius (r=1/2d)

3.14{pi}*16{4 squared}+=50.27

(50.27*2)= 100.54

Now, we need to find the area of the side of the cylinder. We have the given height of 16.8, and now we need to find the length. In order to do that, we must find the perimeter/diameter of the circle with the formula of Pi*Diameter.

if the diameter of the circle is 8, then 3.14*8=25.12.

25.12*16.8=422.016

now we need to add the area of the circles to get total surface area.

100.54+422.016= 522.556cm^2

I hope this helps!

The surface area of the given cylinder is 522.496 cm².

A cylinder is a three dimensional figure which is formed by two parallel circular bases joined by a curved surface.

Center of the two bases is joined by a line called the axis of the cylinder.

Total surface area of cylinder can be found by the total of area of circular bases and the area of curved surface.

Total surface area = Area of Circular bases + Area of curved surface

                               = 2π r² + 2π r h

where r is the radius of the circular base and h is the height of the cylinder. π is the pi constant with value 3.14

Here, r = 8/2 = 4 cm and h = 16.8 cm

Total surface area = 2πr (r + h)

                               = 2π × 4 (4 + 16.8)

                               = 8π × 20.8

                               = 166.4π

                               = 166.4 × 3.14

                               = 522.496

Hence the surface area of the cylinder is 522.496 cm².

Answer:

No problem

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use Pythagorean's theorem. If the sides satisfies Pythagorean theorem, then, they form a right angled triangle.

The longest side is hypotenuse.

Hypotenuse² = base² + altitude²

10²  = 6² +8²

100 = 36 + 64

100 = 100

So, 6cm, 8cm, 10 cm makes an right angles triangle.

The number 12 is an integer number because after the decimal number will be zero. So, Amata is incorrect.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A number is the number zero, a positive regular number, or a negative number with a less sign. The negative numbers are the added substance inverses of the related positive numbers.

The number 12 is an integer number because after the decimal number will be zero. So, Amata is incorrect.

Step-by-step explanation:

This calculator problem can be handled easily by a spreadsheet, which can round to whatever number of digits you desire.

The point is probably to see if you understand that the thousandths place digit will increase by 1 if the ten-thousandths place digit is 5 or more. (That is the case only for problem 2.)

__

Additional comment

When doing this with something that only displays 4 decimal digits, you need to be sure that the 4th digit has not been rounded up to 5. For example, ...

  0.00149  rounds to  0.0015  and rounds to  0.001  (not 0.002)

Usually, you would give yourself this assurance by showing the hundred-thousandths place in the calculation if you're intending to round to thousandths.

Answer:

75

Step-by-step explanation:

When you have 100% of something, it's all of that one thing, right? So if you were to turn 100% into a decimal, it would be 1. This means you can divide any percentage by 100 to turn it into a decimal. So, 30%=.3. When you multiply something by 2, you get two of that thing, right? And just the same, when you multiply something by half, you get half of that thing. This means you can multiply 250 by .3 to get .3 of it, or, 30%.

250*.3=75

Given:

Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg

Rotten tomatoes = 1.5 kg

To find:

How many kilograms of tomatoes were not rotten?

Solution:

Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg

                                                            = [tex]\dfrac{4(10)+4}{10}[/tex] kg

                                                            = [tex]\dfrac{40+4}{10}[/tex] kg

                                                            = [tex]\dfrac{44}{10}[/tex] kg

                                                            = [tex]4.4[/tex] kg

Rotten tomatoes = 1.5 kg

Remaining tomatoes which are not rotten is

Required tomatoes = Tomatoes Sheldon picks - Rotten tomatoes

                                = [tex]4.4-1.5[/tex]

                                = [tex]2.9[/tex] kg

Therefore, the tomatoes which were not rotten is 2.9 kg.
