watermelon seed is 4mm long. How far would a line of 120 watermelon seeds stretch? Write your answer in meters.

Answers

[tex]120[/tex] seeds would be [tex]120 \cdot 4 = 480[/tex] milimeters. This is also [tex]\boxed{0.48}[/tex] meters (since 1000mm is 1 m).
Final answer:

To find the total length of 120 watermelon seeds, each 4mm long, we just need to multiply the length of one seed by the total number of seeds. Then, to convert the total length from millimeters to meters, we divide by 1000. So, a line of 120 watermelon seeds would be 0.48 meters long.

Explanation:

This problem involves simple multiplication to solve it. Since each watermelon seed is 4mm long, to find the length of 120 seeds lined up, we just need to multiply 120 by 4. So, 120 seeds * 4mm/seed = 480mm. To convert millimeters to meters, we divide by 1000 (as there are 1000mm in a meter). So, 480mm = 0.48 meters. Therefore, a line of 120 watermelon seeds would stretch 0.48 meters.

Thank you for posting your question at here on Brainly.

-Charlie

Final answer:

The equation that can be used to solve for acceleration is acceleration = (change in velocity)/time (Option B).

Explanation:

The equation that can be used to solve for acceleration is acceleration = (change in velocity)/time (Option B).

This equation calculates acceleration by dividing the change in velocity by the time taken.

For example, if an object's velocity changes from 10 m/s to 20 m/s in 5 seconds, the acceleration can be calculated using this equation as (20 m/s - 10 m/s) / 5 s = 2 m/s2.

A combined total of $49,000 is invested in two bonds that pay 2% and 6.5%simple interest. The annual interest is $2,5100. How much is invested in each bond?

Answers

let x is the bond pay 2% and y is the pay 6.5%
x + y = 49,000 so x = 49,000 - y
0.02x + 0.065y = 2,510
substitute x = 49,000 - y into 0.02x + 0.065y = 2,510

0.02x + 0.065y = 2,510
0.02(49,000 - y) + 0.065y = 2,510
980 - 0.02y + 0.065y = 2,510
0.045y = 1,530
         y = 34,000
         x = 49,000 - y = 49,000 - 34,000 = 15,000

answer
invested $34,000 in the bond that pays 6.5% rate and $15,000 in bond that pays 2% rate

Final answer:

The amount invested in the 2% bond is $7,500, and the amount invested in the 6.5% bond is $41,500.

Explanation:

Let's assume that the amount invested in the 2% bond is x dollars. Then, the amount invested in the 6.5% bond is $49,000 - x dollars.

The interest earned from the 2% bond is 0.02x dollars, and the interest earned from the 6.5% bond is 0.065($49,000 - x) dollars.

According to the problem, the sum of these two interests is $2,510. So, we have the equation:

0.02x + 0.065($49,000 - x) = $2,510

Simplifying and solving this equation, we find that x = $7,500. Therefore, $7,500 is invested in the 2% bond, and $41,500 is invested in the 6.5% bond.

solve 2x-3y=5 x=4y+5 using the substitution method

Answers

the answer is -1,1 ------ y is -1 and x is 1 because when you substitute for x , which is 4y+5 in the equation 2x-3y=5, you get y as -1. They all you have to do is use y in the equation and figure out what x is as well while solving...:):)
We’ve already been given a value of x so we can use that the find the value of y first.

Substitute x=4y+5 into the first equation
2(4y+5)-3y=5
8y+10-3y=5
Subtract both sides by 10
5y=-5
Divide both sides by 5
y=-1

Now that we have a value of y we can put that value into any equation and we will get the value of x

I will do it to both equations to prove it


2x-3(-1)=5
2x+3=5
Subtract both sides by 3
2x=2
Divide both sides by 2
x=1

x=4(-1)+5
x=1

So your final answer is x=1 and y=-1

Name the complementary to m

Answers

Answer:
The complement of m∠WXV is m∠UXV

Explanation:

Complementary angles are two (or more) angles with a sum of 90 degrees.

Because line WT is dissected perpendicularly by line UX, two 90° angles are formed in ∠TXU and ∠WXU. We know that they are both 90° because of the box on ∠TXU. ∠TXU and ∠WXU are supplementary angles -- two angles that occupy the same line but are dissected by a perpendicular line forming two angles with a sum of 180 degrees.

If ∠TXU + ∠WXU = 180, and ∠TXU = 90, then ∠WXU must also equal 90:
90 + ∠WXU = 180
90 - 90 + ∠WXU = 180 - 90
0 + ∠WXU = 90
∠WXU = 90°

As we see in the diagram, ∠WXU is dissected by line SV. Because of this, it is broken into the two angles of ∠WXV and ∠UXV. We already established that ∠WXU is 90°. Therefore the sum of these two angles formed must equal 90°, which, in turn, means they are complementary angles. They complement one another.

Therefore, the complement of ∠WXV is ∠UXV

A local coffee shop serves 2/9 as many customers as a shop run by a national coffee chain. The shop run by the chain serves 502 customers day. About how many customers does the local shop serve in a day

Answers

Answer:

about 112 customers

Step-by-step explanation:

we know that

To find out  how many customers does the local shop serve in a day, multiply the fraction 2/9 by the number of customers that the shop run serve in a day

Let

x ----> the number of customers that the shop run serve in a day

y ----> the number of customers that the local shop serve in a day

[tex]y=\frac{2}{9}x[/tex]

we have

x=502

substitute the value of x in the equation

[tex]y=\frac{2}{9}(502)[/tex]

[tex]y=111.6[/tex]

Round up

so

about 112 customers

The local shop serves about 112 customers in a day

Charlene has a budget of $65. Beau and Belle dresses are $76.48. What inequality can be used to calculate how much of a markdown Beau and Belle must take for Charlene to stay in her budget

Answers

76.48
- 65.00
----------
$11.48
The answer for how much of a markdown would be 15%
The inequality
[tex]76.48 \geqslant 65 + .15[/tex]
76.48 is greater than or equal to 65 + 15%

Final answer:

To find out how much Beau and Belle must markdown the dress for Charlene to stay within her budget of $65, we use the inequality 76.48 - m ≤ 65, which solves to m ≥ 11.48, meaning the dress needs a markdown of at least $11.48.

Explanation:

To determine the markdown Beau and Belle must offer for Charlene to afford the dress within her budget, we can set up an inequality. Let's denote the markdown as m. The original price of the dress is $76.48, and Charlene's budget is $65. Therefore, the dress's price after the markdown should be less than or equal to $65. The inequality that models this scenario is:

76.48 - m ≤ 65

This inequality states that the original price of the dress minus the markdown m should be less than or equal to Charlene's budget of $65. To find out how much of a markdown is needed, we will solve for m.

Subtracting $76.48 from both sides of the inequality:

-m ≤ 65 - 76.48

-m ≤ -11.48 (This indicates that the markdown must be at least $11.48)

To express m as a positive number, we multiply both sides of the inequality by -1, remembering to reverse the inequality symbol:

m ≥ 11.48

Therefore, Beau and Belle must markdown the dress by at least $11.48 for Charlene to stay within her budget constraint.
