The equation of the line in slope intercept form is [tex]y=2x+1[/tex]

Explanation:

The point A is [tex](1,3)[/tex]

The equation of line for B is given by [tex]y=2x-2[/tex]

We need to determine the equation of line in slope intercept form passing through the point A and parallel to line B.

Since, the lines of equation are parallel, their slopes are same.

Thus, the slope is [tex]m=2[/tex]

Now, let us substitute the point [tex]A(1,3)[/tex] and slope [tex]m=2[/tex] in the slope - point formula, we have,

[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]

 [tex]y-3=2\left(x-1\right)[/tex]

 [tex]y-3=2x-2\right)[/tex]

       [tex]y=2x-2+3\right)[/tex]

       [tex]y=2x+1[/tex]

Thus, the equation of the line in slope - intercept form is [tex]y=2x+1[/tex]

Step-by-step explanation:

2. To find area, you use this equation: A = l*w

Let's input the values we do know to find the width.

96 = 12 * w

Divide both sides by 12 to isolate the w.

8 = w

The width is 8 cm.

3. We need the find the area of the floor to figure out how many square meters they need. to find area, we multiply the length by the width.

3 * 2 = 6

You need 6 sq. m.

4. To find the circumference, use the equation: C = 2 * pi *r

To find the radius, divide the diameter by 2.

3/2 = 1.5

C = 2pi(1.5)

C = 3pi

The circumference is 3pi. This can also be simplified to 9.42 or 9.4

5. To find the amount of square cm. it covers, multiply the length and width.

40 * 35 = 1,400

The surface covers 1,400 sq. cm.

6. To find circumference, use this equation: C = d * pi

Input the values you do know to find the diameter

15.7 = d * pi

divide both sides by pi to isolate d

4.77 = d

The diameter is approximately 4.8 cm.

7. To find area, multiply length by width. Since we know all sides of a square are the same, you can multiply 15 by 15 to get the answer.

15 * 15 = 225

The area is 225 sq. cm.

8. To find area, use this equation: A = l * w

put the values you know into the equation to find the length.

60 = l * 6

divide both sides by 6 to isolate the l

10 = l

The length is 10 cm.

9. To find the area of a square, the equation is: A = s^2

Input the values you know to find the length of a side.

81 = s^2

Find the square root of both sides to isolate the s.

9 = s

The length of one side is 9 cm.

10. To find the area of a circle, use this equation: A = pi * r^2

Input the values you know and solve for r.

201 = pi * r^2

Find the square root of both sides and divide both sides by pi to isolate the r.

7.998 = r

The radius is approximately 8 cm. Multiply this value by 2 to find the length of the diameter.

8 * 2 = 16

The diameter is approximately 16 cm.

The first student read faster than the second student.

Step-by-step explanation:

Step 1:

To determine how long each student takes to read a book, we divide the time taken to read by the number of books read in that period.

Time taken to read a book = [tex]\frac{time taken to read}{number of books read in that period}[/tex].

In the given table, the second column values are times taken to read and the first column represents the number of books read in that period.

Step 2:

For the first student, the time taken is calculated.

The first student's time taken to read a book = [tex]\frac{30}{3}[/tex] = [tex]\frac{50}{5}=\frac{70}{7}[/tex] = 10 minutes to read a book.

Step 3:

Similarly, the time taken to read a book is calculated for the second student.

The first student's time taken to read a book = [tex]\frac{24}{2}=\frac{48}{4}=\frac{72}{6}[/tex] = 12 minutes to read a book.

Step 4:

Now we compare the times taken. The first student read a book in 10 minutes while the second student took 12 minutes for a book. So the first student read faster.

Answer:

0.86liters

Step-by-step explanation:

860cm³=0.86dm³=0.86liters

The capacity of the container is 860 cm³.

To find the capacity of the container, we need to understand that the volume and the capacity are essentially the same thing when referring to containers.

The volume of a container is the amount of space it occupies, and the capacity is the amount of fluid or substance it can hold. Since the volume is already given in cubic centimetres (cm³), which is a unit of volume, it directly translates to the capacity of the container.

Therefore, without the need for any conversion or further calculation, we can state that the capacity of the container is 860 cm³. If one were to express this capacity in litres, knowing that 1 liter is equivalent to 1000 cm³, we could perform a conversion:

[tex]\[ \text{Capacity in liters} = \frac{\text{Capacity in cm}^3}{1000} \][/tex]

[tex]\[ \text{Capacity in liters} = \frac{860}{1000} \][/tex]

[tex]\[ \text{Capacity in liters} = 0.86 \][/tex]

So, the capacity of the container is 0.86 litres, which is equivalent to 860 cm³.

Step-by-step explanation:

10^3 = 10 * 10 * 10 = 1000

When you multiply 42.12 by 10^3, you are multiplying 42.12 by 1000.

When you multiply a number by a power of 10, such as 10, 100, 1000, etc., move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10.

42.12 * 1000 = 42,120

Final answer:

To find the product of 42.12 and 10³, move the decimal point in 42.12 three places to the right because 10³ has three zeros. Thus, the product is 42120.

Explanation:

To find the product of 42.12 and 10³, you need to move the decimal point in 42.12 three places to the right because 10³ has three zeros. Multiplying by powers of ten is simplified by moving the decimal point to the right for each zero in the power of ten. For instance, multiplying 2.4 by 100 involves moving the decimal two places to the right to get 240, since 100 has two zeros.

When you multiply 42.12 by 10³, which is the same as multiplying by 1000 (10 x 10 x 10), you're effectively shifting the decimal point three places to the right. If there aren't enough digits, you can use zeros as placeholders. However, in this case, there are sufficient digits to move the decimal without adding additional zeros.

Therefore, 42.12 multiplied by 10³ would be 42120. This is because you move the decimal point three places to the right to account for the three zeros in 10³, changing 42.12 into 42120.

The area is 9,600 square yards.

Carrie's walk forms a right-angled triangle, with the two legs being her north and west paths, and the hypotenuse being the diagonal path back to the start. To find the area of the triangle, we can apply the formula for the area of a right-angled triangle, which is (1/2) * base * height. In this case, the base is her westward walk (80 yards), and the height is her northward walk (240 yards).

Using the formula, the area equals: (1/2) * 80 yards * 240 yards, yielding an area of 9,600 square yards.

Answer: $1875

Step-by-step explanation:

If 80% of original price= $1500

Let the remaining 20% be x

Write as:

80/100 = $1500

Answer:

20 quarts of 6% butterfat milk and 40 quarts of 3% butterfat milk is used to make 60 quarts of 4% butterfat milk.

Step-by-step explanation:

We are given the following in the question:

Let x quarts of 6% butterfat milk be used and y quarts of 3% butterfat milk be used to make 60 quarts of 4% butterfat milk.

Thus, we can write the equation:

[tex]6\%\times x + 3\%\times y = 4\%\times 60\\6x + 3y = 240[/tex]

Total amount of 3% butterfat milk = 60

Thus, we can write the equation:

[tex]x+y = 60[/tex]

Solving the two equation, we get,

[tex]6x + 3y-(3x+3y) = 240 - 3(60)\\3x = 240-180\\3x = 60\\x = 20\\y = 60-20 = 40[/tex]

Thus, 20 quarts of 6% butterfat milk and 40 quarts of 3% butterfat milk is used to make 60 quarts of 4% butterfat milk.

To get 60 quarts of 4% butterfat milk, mix 20 quarts of 6% butterfat milk with 40 quarts of 3% butterfat milk by setting up and solving a system of linear equations.

To solve this problem, we can set up a system of equations based on the quantities and percentages of butterfat in the milk types. Let's call the amount of 6% butterfat milk x quarts and the amount of 3% butterfat milk y quarts. According to the question, we want to end up with 60 quarts of 4% butterfat milk. Therefore, we have:

First, we multiply the second equation by 100 to simplify the percentages:

6x + 3y = 4 × 60

Simplify the right side:

6x + 3y = 240

Now, divide by 3 to get:

2x + y = 80

We can subtract the first total volume equation from this new equation:

(2x + y) - (x + y) = 80 - 60

Omit the similar terms to solve for x:

x = 20

We substitute x back into the initial total volume equation:

20 + y = 60

And solve for y:

y = 60 - 20

y = 40

Therefore, to get 60 quarts of 4% butterfat milk, 20 quarts of 6% butterfat milk and 40 quarts of 3% butterfat milk must be mixed together.

Answer: 34

Step-by-step explanation:

Final answer:

To estimate 34.02, we would round it to the nearest whole number which is 34.

Explanation:

When asked to estimate 34.02, we look for a number that is close in value but simpler or more convenient to use.

Estimation often involves rounding to a certain place value depending on the level of precision required.

In this case, we can round to the nearest whole number. 34.02 is very close to 34, so the estimated value is 34.

This is based on traditional rounding rules where if the digit right after the place you are rounding to is less than 5, you keep the digit the same. If it is 5 or more, you round up. Since the decimal part .02 is less than .05, we do not round up.

The ratio of the volume of the cone to the cylinder is 2/3.

We have,

The volume of a cone is given by the formula:

= (1/3)πr²h

The volume of a cylinder is given by the formula:

= πr²h

The radius of both shapes as r, and since the cone is twice as tall as the cylinder,

h(cone) = 2 h(cylinder)

Ratio = V(cone) / V(cylinder)

= [(1/3) π r² (2h(cylinder)] / (πr²h(cylinder))

= (2/3) h(cylinder) / h(cylinder)

= 2/3

Therefore,

The ratio of the volume of the cone to the cylinder is 2/3.

Both area and perimeter are the same. They have the same shape and dimensions.

This is because congruency means that the two figures are identical, one is the clone of the other.

Two congruent figures have identical shape and size, meaning their perimeters and areas are both equal.

If two figures are congruent, this means that they are identical in shape and size. Congruent figures are essentially the same figure superimposed from one location to another. According to the definition of congruent figures, corresponding angles and sides are equal. Therefore, since the dimensions of congruent figures are the same, the perimeters of the figures must also be the same. This is because perimeter is a linear measure, which is the sum of the lengths of the sides of a figure.

Similarly, since congruent figures are identical in size, their areas must also be the same. Area is a measure of the extent of a 2-dimensional surface enclosed by a figure. Since the figures are congruent, they cover the same amount of 2-dimensional space, thus their areas are equal. Theorems 9 and 12 mentioned in the reference material confirm these properties.

In questions it's given that ∠B = 85°, which is an error and correct answer is ∠B = 95°.

Step-by-step explanation:

We know that sum of alternate angles in a parallelogram is 180°. Using this property, we will solve the question! We have a parallelogram inscribed in a circle with measure of angles as  ∠A=100° and ∠D=85°. Now, according to property : ∠A + ∠C = 180° and ∠D + ∠B = 180°.

Let's consider for ∠D + ∠B = 180°:

⇒ 85° + ∠B = 180°

⇒∠B =  180° - 85°

⇒∠B = 95°

Also, for ∠A + ∠C = 180°:

⇒ 100° + ∠C = 180°

⇒∠C =  180° - 100°

⇒∠C = 80°

In questions it's given that ∠B = 85°, which is an error and correct answer is ∠B = 95°.
