I need help pleaseeeeee

Answer:

Step-by-step explanation:

To know the number of rows of the beads are used on the bookmark, we just need to divide.

Notice that the bookmark is 20 centimeters long, and each bead is 4 milimiters. In order to divide, we need to transform centimeters to millimeters.

We know that 1 centimeter is 10 millimeters, that means 20 centimeters is 200 millimeters.

Then, the division is

[tex]\frac{200mm}{4mm} =50[/tex]

Therefore, there are 50 beads on the bookmark.

51 rows of beads are used on the bookmark.

To determine the number of rows of beads on the bookmark, we need to follow these steps:

 1. Convert the length of the bookmark from centimeters to millimeters to match the unit of measurement for the spacing between rows of beads. Since there are 10 millimeters in a centimeter, the bookmark is [tex]\( 20 \text{ cm} \times \frac{10 \text{ mm}}{1 \text{ cm}} = 200 \text{ mm} \)[/tex]  long.

2. Determine the distance between each row of beads. The problem states that there is a row of beads every 4 millimeters.

3. Calculate the number of intervals between the beads along the bookmark. To do this, divide the total length of the bookmark by the spacing between each row of beads: [tex]\( \frac{200 \text{ mm}}{4 \text{ mm/row}} = 50 \) intervals.[/tex]

4. Since we have an interval at each end of the bookmark where a row of beads is placed, we already have two rows of beads. For each interval between these end rows, there is an additional row of beads. Therefore, we have one more row of beads than the number of intervals.

5. Add one to the number of intervals to account for the starting row of beads: [tex]\( 50 \text{ intervals} + 1 = 51 \)[/tex] rows of beads.

Thus, there are 51 rows of beads used on the bookmark.

Answer:

36π

Step-by-step explanation:

Since you have to use terms of pi you just leave out pi out of the formula

A = πr² so it would be

A = r²       Radius is half of diameter so half of 12 = 6

A = 6²

A = 36

Than you add pi

36π

Answer:

1) 28 weeks or A

2) 14 or c

Step-by-step explanation:

1) 8/2= 4

   4 multiplied by 7 = 28

answer is 28

2) 4x-7=49

        add 7 to both sides

    4x=49+7

     4x=56

         divide 56 by 4

    56/4=12

answer is 12

Answer:

Step-by-step explanation:

It takes Mr. Holloway 8 weeks to make 2 guitars. Write this as a rate.

8 weeks

2 guitars

Divide the numerator and denominator by 2 to find the unit rate.

8 weeks÷2

2 guitars÷2

=

4 weeks

1 guitar

It takes Mr. Halloway 4 weeks to make 1 guitar. You want to find how long it will take him to make 7 guitars. Write a proportion.

To get from 1 to 7, multiply by 7. Multiply the numerator and denominator by 7 to find how long it will take Mr. Halloway to make 7 guitars.

4 weeks7

1 guitar7

=

28weeks

7 guitars

It will take Mr. Halloway 28 weeks to make 7 guitars.

Answer: [tex]-2x^2 + 10x-8[/tex]

Step-by-step explanation:

To find the product of the binomials, we first need to find the linear equations for the lines.

Using the rise over run method for f(x), we can see that the line rises 2 units for every 1 unit ran. 2/1 = 2, so we know the slope is 2, and we can see that the y-intercept on the graph is -2.

Equation: [tex]f(x) = 2x-2[/tex]

Using the rise over run method for g(x), we can see that the line rises -1 unit for every 1 unit ran. -1/1 = -1, so we know the slope is -1, and we can see that the y-intercept on the graph is 4.

Equation: [tex]g(x) = -x+4[/tex]

Multiplying the binomials:

[tex](2x-2)(-x+4)[/tex]

Use the FOIL method:

First: 2x * -x

Outside: 2x * 4

Inside: -2 * -x

Last: -2 * + 4

[tex]-2x^2+8x+2x-8\\\\-2x^2 + 10x-8[/tex]

The ball costs $0.05 and the bat costs $1.05. We derived these amounts by setting up an equation based on the given information that the total cost is $1.10 and the bat costs $1 more than the ball, then solving for the ball's price.

To answer the classic problem about the cost of a bat and ball, let's denote the cost of the ball as 'x' dollars. Since the bat costs $1 more than the ball, the cost of the bat is 'x + $1.00'. The total cost is $1.10, and we know the sum of the bat and ball together is:

x + (x + $1.00) = $1.10

To find the value of x, solve the equation:

2x + $1.00 = $1.10

Subtract $1.00 from both sides to isolate the term with x:

2x = $0.10

Divide both sides by 2 to find the cost of one ball:

x = $0.05

So, the ball costs $0.05 and the bat costs $1.05 since it's $1.00 more expensive than the ball.

Answer:

y=43

Step-by-step explanation:

y=x+10

y=33+10

y=43

To find the value of y when x=33, knowing that x and y are directly proportional, we first calculate the proportionality constant from the given values and apply it to find y=88 when x=33.

The task is to find the value of y when x is given, knowing that x and y are directly proportional. Thus, we first find the proportionality constant using the given values of x=6 and y=16. The formula for direct proportionality is y = kx, where k is the proportionality constant. Solving for k we get k = y/x => k = 16/6. Once we have the value of k, we can find y for x=33 by rearranging the formula to y = (16/6) * 33.

After performing the calculation, we find:

Therefore, y is 88 when x is 33, as they are directly proportional.
