Answer:

3 bottles

Step-by-step explanation:

Given that :

Total liters of fertilizer = 5/7 litres

Amount put into each smaller bottle = 1/5 liters

Number of small bottles filled :

Total liters of fertilizer ÷ amount put into smaller bottles

5/7 litres ÷ 1/5 litres

5 /7 * 5 /1

= 25 / 7

= 3.57

Hence, 3 bootles was filled

13. 9.77 inches (rounded to 3 s.f.)

14. 249m² (rounded to 3 s.f.)

Step-by-step explanation:

13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2

[tex]\frac{80}{360}[/tex] × pi × 7 × 2 = 3[tex]\frac{1}{9}[/tex]pi

                       = 9.77 inches (rounded to 3 s.f.)

14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r

[tex]\frac{285}{360}[/tex] × pi × 10 × 10 = 79[tex]\frac{1}{6}[/tex]pi

                          = 249m² (rounded to 3 s.f.)

Answer:

[tex]924.96\ cm^3[/tex]

Step-by-step explanation:

Given that,

The diameter of a hockey puck, d = 7.6 cm

Height, h = 3.4 cm

We need to find the volume of the volume of a cylindrical package containing six pucks.

Volume of 1 puck,

[tex]V=\pi r^2 h\\\\=3.14\times (3.8)^2\times 3.4\\\\=154.16\ cm^3[/tex]

Volume of 6 pucks,

[tex]V=6\times 154.16\ cm^3\\\\=924.96\ cm^3[/tex]

So, the volume of the 6 puck is [tex]924.96\ cm^3[/tex].

Given the dimensions of a single hockey puck, we want to find the volume of a cylindrical package containing six pucks. We will see that the volume must be 925 cm^3

So the volume of a cylinder of diameter D and height H is:

V = 3.14*(D/2)^2*H

Here we have:

Then the volume of each single puck is:

V = 3.14*(7.6cm/2)^2*3.4cm = 154.16cm^3

Then the volume of a package that contains 6 of these must have at least 6 times that volume:

6*V = 6*154.16cm^2 = 924.96 cm^3

Rounding to the next cubic centimeter we get 925 cm^3

So the volume of the package must be 925 cm^3

The value of variable r in the equation [tex]10r+4=8[/tex] is [tex]\mathbf{r=0.4}[/tex]

Step-by-step explanation:

We need to find the value of variable r in the equation [tex]10r+4=8[/tex]

Step 1: Write the equation

[tex]10r+4=8[/tex]

Step 2: Subtract 4 on both sides

[tex]10r+4-4=8-4\\10r=4[/tex]

Step 3: Divide both sides by 4

[tex]\frac{10r}{10}=\frac{4}{10}\\r=0.4[/tex]

So, The value of variable r in the equation [tex]10r+4=8[/tex] is [tex]\mathbf{r=0.4}[/tex]

Answer:

Meters

Step-by-step explanation:

The position of an object is its location at a given time. Which is subjected to change with respect to time, especially for any object which has potential energy.

In the standard unit of measurements (SI unit), it is required that distance which is a measure of length is recorded in meters. Thus, the best unit of measurement to use when recording a change in the position of an object is meters.

Answer:

SAS

Step-by-step explanation:

Here, we want to check for if the triangles are similar

Firstly, we notice a marked angle on both triangles

This shows that we have an angle that is similar in both triangles

Also, if we check, we can deduce that the bigger looks like a scaled version of the smaller one to a tune of 3

This means that the sides of the smaller when multiplied by 3 gave the bigger

since the sides are in proportion, then the triangles are similar. It is not alone that the sides must be equal; once they are in proportion, then the triangles are similar triangles

Baker's Best

Step-by-step explanation:

Given data

For Baker's Best  

5 biscuits and costs $0.69 per can

The cost per  biscuits

=0.69/5

=$0.14 per  biscuit

For Butter Bee Canned

8 biscuits and costs $1.29 per can

The cost per  biscuits

=1.29/8

=$0.16 per  biscuit

Hence the best buy is Baker's Best which offers $0.14 per biscuit

Answer:

y2-y1/x2-x1 = 3-3/4-(-6) = 0/10

y = mx+b = 3 = 0(4) + B = B = 3

y = mx+b = y = 0x + 3

Step-by-step explanation:

If you know two points on a line, you can use them to write the equation of the line in slope-intercept form. The first step will be to use the points to find the slope of the line. This will give you the value of m that you can plug into y = mx + b. The second step will be to find the y-intercept.

Answer:

y-2x3

Answer:

False

Step-by-step explanation:

This is right, I did this in my class.

Answer:

Prolly cause it's not in slope intercept form.

Step-by-step explanation:

To make the equation into slope-intercept form, first subtract 6x from both sides.

-2y = -6x + 12

Divide everything by -2.

y = 3x - 6

There is your slope-intercept equation. -6 is the y-intercept and 3 is the positive slope.

Answer:

Area of the new parallelogram = n(b × h)

Step-by-step explanation:

Area of a parallelogram = Base × Height

Let

b = the base

h = the height of the original parallelogram.

Each dimension of a parallelogram is multiplied by a positive number n.

Write an expression for the area of the new parallelogram.

Area of the new parallelogram = Base × Height

Base = b * n

bn

Height = h * n

= hn

Area of the new parallelogram = bn × hn

= n(b × h)

Area of the new parallelogram = n(b × h)

The area of a 2D form is the amount of space within its perimeter. The total surface area of the formed figure is 615.75216 cm².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Given that the total surface area of one hemispherical object is 462 square centimeters, therefore, we can write,

The total surface area of the hemisphere = 3πr²

462 cm² = 3πr²

r² = 462/(3π) cm²

r² = 49.0197 cm²

r = 7 cm

Now, when the two hemispheres will be attached, the total surface area of the formed figure will be equal to the total surface area of a sphere,

Therefore, we can write,

Total surface area = 4πr²

                              = 4 × π × (7 cm)²

                              = 615.75216 cm²

Hence, the total surface area of the formed figure is 615.75216 cm².
