Since 43 is a 2 digit odd number is it a composite and why

Answers

Answer 1

the answer is it is also prime

Answer 2

It is not composite because nothing times itself equals 43. It is prime though which means that nothing times itself equals it. So that means that it is not composite it is prime.

(55 km/h) * (1 mi)/(1.609344 km) ≈ 34.2 mi/h

_____
You can do units conversions pretty easily by multiplying by a conversion factor whose value is 1. That is, since
.. 1 mi = 1.609344 km
dividing by the left side we have
.. (1 mi)/(1.609344 km) = 1
This factor has the convenience that it will cancel km and give mi when multiplied by some number off km. That is what we did above. (The "per hour" just went along for the ride. It did not get involved in the units conversion.)

To evaluate this situation, you need to look at the given information. We know that b is 2.1 and that the expression b is put into is 8b-12. So, just plug in for b.
8*2.1 - 12. Use the order of operations to ensure a correct answer. So, multiply first. 8 * 2.1 is 16.8. Nou, subtract. 16.8 - 12 = 4.8. So, the final answer is 4.8

a plane takes off at 6 am, traveling north at 270 mph. a jet takes iff at 7 am, traveling north at 460 mph. at what time will the jet overtake the plane?

Answers

Remember the distance-rate-time f[tex]t = 0.704 hrs[/tex]ormula:
[tex]d=rt[/tex]

Now, if the jet overtakes the plane, then at some point their distances will be the same. This means their rate * time will be equal.

Let's call the rate for the first plane, r1, and the rate for the second plane, r2. If we set time as t, then we can create ourselves a formula. However, we have to add one to the time of the first plane since it leaves one hour earlier. In the end, we should have something like this:
[tex]r_{1}(t+1)= r_{2}t [/tex]

If you plug in the values, you should get:

What is the percent of increase?

Answers

%2. hope that helped

Answer:

The percent increase is [tex]$10\%$.[/tex]

Explanation:

To find the percent increase, we use the formula:

[tex]\[\text{Percent Increase} = \left( \frac{22 - 20}{20} \right) \times 100\%\][/tex]

Given:

- Original price = $20

- New price = $22

Substitute these values into the formula:

[tex]\[\text{Percent Increase} = \left( \frac{22 - 20}{20} \right) \times 100\%\][/tex]

[tex]\[\text{Percent Increase} = \left( \frac{2}{20} \right) \times 100\%\][/tex]

[tex]\[\text{Percent Increase} = \left( 0.1 \right) \times 100\%\][/tex]

[tex]\[\text{Percent Increase} = 10\%\][/tex]

So, the percent increase is [tex]$10\%$.[/tex]

The Students at Sunnyside School built a rectangular pyramid of aluminum cans for a world record. The top layer had 2 rows with 3 cans in each row. The second layer had 4 rows of 6 cans. The third layer had 8 rows of 12 cans. How many cans were in the eighth layer of the pyramid?

Answers

Final answer:

The eighth layer of the pyramid will have 280,896 cans.

Explanation:

To find the number of cans in the eighth layer of the pyramid, we need to observe the pattern in the number of rows and cans in each layer. The pattern is that each layer doubles the number of rows and the number of cans in each row. The eighth layer will have 2^7 (128) rows and 3^7 (2187) cans in each row. Therefore, there will be a total of 128 * 2187 = 280,896 cans in the eighth layer of the pyramid.

what expression is equivalent to 2.2-2.5?

Answers

Hi Camrynb10705oxknsv!
So let's take a look at the answers they give. A is 2.5 - 2.2 and all that is is switching the numbers so that isn't right. B they do addition instead of subtraction so that can't be right. C they do 2.2 + (-2.5) and when you add a negative number it's like subtraction because a negative number is under 0 and so your adding a number under 0 so you go down. So the answer is C.
If you need me to explain it different let me know. Hope this helps!

The answer is C. How we know:
The origional expression would equate to -0.3
The reason A is incorrect is that you can not change the order of subtraction. This answer equates to 0.3.
The reason B is incorrect is that adding is not the same as subtracting. This answer equates to 4.7.
The reason D is incorrect is that subtracting a negative is the same as adding. This would equate to 4.7
The reason C is correct is that adding negative is the same as subtracting. This would equate to -0.3.

Fashion Phreddy buys 5 shirts and 3 ties for 91 on the bargain bus. Billy joe bob buys 8 shirts and 5 ties for 146. If all the shirts sold for the same price and each ties were priced identically. How much was each shirt and tie.

Answers

Assume that the price of the T-shirt is x and the price of the tie is y.

Fashion Phreddy buys 5 shirts and 3 ties for 91. This means that:
5x + 3y = 91 .........> equation I
5x = 91-3y
x = 18.2 - (3/5) y ..........> equation II
Billy joe bob buys 8 shirts and 5 ties for 146. This means that:
8x + 5y = 146 ...........> equation III

Substitute with equation II in equation III:
8(18.2 - (3/5) y) + 5y = 146
145.6 - 4.8y + 5y = 146
0.2y = 0.4
y = 2
Substitute in equation II to get the value of x:
x = 18.2 - (3/5) (2) = 17

Based on the above calculations:
price of T-shirt = x = 17
price of tie = y = 2

1. 5:4:2

2(17.4)=34.8
add all the lengths together to find the amount of total string
87+69.6+34.8= 191.4

im not sure how to work the second one out.

Final answer:

The total length of the string before being cut was 319 cm. The bookstore, given the ratio of 6:5:9 for fiction books, textbooks, and workbooks, sold a total of 1650 fiction books and textbooks in a month.

Explanation:

Answer to String Ratio Problem

Let's represent the length of the longest piece of string as 5x, the medium piece as 4x, and the shortest piece as 2x, based on the given ratio 5:4:2. According to the problem, the longest piece is 87 cm longer than the shortest piece. Thus, we have:

5x - 2x = 87 cm

3x = 87 cm

x = 29 cm

Now, to find the total length of the string before cutting, we add up all the pieces:

Total length = 5x + 4x + 2x = 11x = 11(29 cm) = 319 cm

So, the string was 319 cm long before it was cut.

Answer to Bookstore Ratio Problem

In the bookstore problem, we're given the ratio of fiction books, textbooks, and workbooks sold as 6:5:9, respectively, and that 1350 workbooks were sold. If we denote the common ratio multiplier as y, we can represent the amounts of each as follows:

Fiction books = 6y, Textbooks = 5y, Workbooks = 9y = 1350

To find y, we solve 9y = 1350:

y = 150

Now, we can calculate the total number of fiction books and textbooks sold:

Fiction books = 6y = 6(150) = 900

Textbooks = 5y = 5(150) = 750

Total fiction books and textbooks = 900 + 750 = 1650

The bookstore sold a total of 1650 fiction books and textbooks.

Answers

3/4n - 18 = 1/4n - 14

We need to isolate "n"

So, add 18 to both sides.

3/4n = 1/4n - 14 - 18

Then, subtract 1/4n from both sides.

3/4n - 1/4n = -14 - 18

*Note : Since "n" has the same denominator (bottom number in a fraction), then we simply need to look at the top numbers (numerators) and simplify those.

Simplify.

2/4n = -32

Then, multiply both sides by 4 so that we get rid of fractions.

4 · 2/4n = -32 · 4

Answers

y = -5x + 15

You can use point slope formula to get the answer

Answer: x + 5y - 15 = 0

Step-by-step explanation:

First, we find the slope

Given : x₁ = 2 y₁= 5 x₂= 3 y₂=0

m = y₂ - y₁ / x₂ - x₁

m = 0-5 / 3-2

m = -5 / 1 = -5

equation of a straight line;

y - y₁ = m (x - x₁)

y - 5 = -5(x - 2)

y - 5 = -5x + 10

y + 5x - 15 = 0
