please answer quickly thanks :) good morning btw

The question involves understanding multiplication and division principles. Section A has 180 seats in total (12 rows * 15 seats). Section B, having the same total number of seats but only 10 rows, would have 18 seats per row.

The question involves the basic principles of mathematics, specifically dealing with multiplication and division concepts. Section A of the theater has 12 rows of 15 seats each, which totals to 180 seats (12 * 15 = 180). As it is stated that Section B has the same number of seats as Section A but only consists of 10 rows, each row in Section B must, therefore, contain 18 seats (180 / 10 = 18).

This is an application of the principle that if a total quantity remains the same, and it is divided into fewer groups, then each group will contain more than before. Therefore, even though Section B has fewer rows than Section A, each row in Section B contains more seats, leading to the same total.

There are 18 seats in each row of Section B.

To find out how many seats are in each row of Section B, let's first calculate the total number of seats in Section A:

Total seats in Section A = 12 rows × 15 seats per row = 180 seats

Since Section B has the same total number of seats as Section A but only 10 rows, we can find out how many seats are in each row of Section B by dividing the total number of seats in Section B by the number of rows in Section B:

Seats per row in Section B = Total seats in Section B / Number of rows in Section B

We already know the total seats in Section B is 180, and the number of rows in Section B is 10.

Let's plug these values into the formula:

Seats per row in Section B = 180 seats / 10 rows = 18 seats

The complete question is-

In a theater, Section A contains 12 rows of 15 seats each. Section B has the same total number of seats as Section A but contains only 10 rows. How many seats are in each row of Section B?

i think it's 0.25•10+0.1•d=4.90

Remark

4.90 is all by itself. It is the total amount of money.  It should not be multiplied or divided by anything. So A is wrong.

B: requires a decimal place somewhere in the 490. It would take quite a few dimes to make up 490 dollars. B is wrong.

C: 25 is a decimal (0.25) without a multiplication by 10 present. The 25 should not be alone in any event. C is wrong.

D: is the correct answer. It is what you must use to find out how many dimes there are. Although did not ask for it, you need 24 dimes.

5 + 62 = 18p - 10p

67 = 8p

p = 67:8

p = 67/8 or 8.375

Answer:

p = -8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10p + 5 =  18p −6/2  

10p + 5 = 9p + −3(Distribute)

10p + 5 = 9p − 3

Step 2: Subtract 9p from both sides.

10p + 5 − 9p = 9p − 3 − 9p

p + 5 = −3

Step 3: Subtract 5 from both sides.

p + 5 − 5 = −3 − 5

p = −8

Simply multiply all of the fractions with the total number of marbles

48(2/3)(3/4)

Final answer:

There are 24 marbles that are red and have stripes in the box, calculated by first determining the total number of red marbles (32) and then finding three-fourths of those to be striped.

Explanation:

The question involves finding out how many red and striped marbles are in a box, given that two-thirds of the marbles are red and three-fourths of the red marbles are striped. There are 48 marbles in total.

To find the total number of red marbles, we multiply the total number of marbles by two-thirds:

48 marbles × ⅓ (red marbles) = 32 red marbles

Next, to find out how many of the red marbles are striped, we multiply the number of red marbles by three-fourths:

32 red marbles × ¾ (striped marbles) = 24 striped red marbles

So, 24 of the marbles in the box are red and have stripes.

Mrs. Payne can buy the notepads in 5 different ways: 0 packs, 1 pack, 2 packs, 3 packs, or 35 single pads. The number of notepads in each option is either a multiple of 10 or 35.

To find all the different ways Mrs. Payne can buy the notepads, we need to consider two scenarios: buying in packs of 10 and buying as single pads. Let's start with buying in packs of 10. The number of packs Mrs. Payne can buy ranges from 0 to 3, since if she buys 4 packs she would have 40 notepads which is more than she needs. So the different ways she can buy notepads in packs of 10 are 0 packs, 1 pack, 2 packs, and 3 packs.

Next, let's consider buying single pads. If Mrs. Payne buys 35 single pads, she would exactly reach her requirement. So another way she can buy the notepads is by purchasing 35 single pads. In total, there are 5 different ways she can buy the notepads: 0 packs (0 notepads), 1 pack (10 notepads), 2 packs (20 notepads), 3 packs (30 notepads), or 35 single pads.

From the chart, we can observe that each option involves a multiple of 10 notepads except for the last option. This indicates that the number of notepads can be obtained by multiplying a whole number by 10, or in the case of 35 single pads, the count is not a multiple of 10.

Final answer:

To find 3/8 multiplied by 4/5, multiply the numerators together and the denominators together and then simplify the resulting fraction. The solution in simplest form is 3/10.

Explanation:

To multiply two fractions, you multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together. For the multiplication of 3/8 × 4/5, we multiply the numerators 3 and 4 to get 12, and the denominators 8 and 5 to get 40.

The result of this multiplication is 12/40. However, this fraction can be simplified. We notice that both the numerator and the denominator are divisible by 4. Thus, we divide both by 4 to get the simplest form: 12 ÷ 4 is 3, and 40 ÷ 4 is 10, resulting in the fraction 3/10.

So, 3/8 × 4/5 in its simplest form is 3/10.

ANSWER

Options B, C and D have exactly 2 significant figures.

EXPLANATION

To see whether the numbers have exactly 2 significant figures, round all to 2 significant figures. The ones that remains the same have exactly 2 significant figures.

[tex]302\approx 300[/tex]yards to 2.s.f

[tex]980\approx 980[/tex]gallons to 2.s.f

[tex]1200\approx 1200[/tex]feet to 2.s.f

[tex]84\approx 84[/tex]litters to 2.s.f\

[tex]6,040\approx 6,000[/tex]meters to 2.s.f

First of all, add 7 to both sides, in order to cancel the -7:

[tex] -7 + 4n +7= 9+7 [/tex]

As we said, the -7 on the left hand side cancels out, while we can add it to the 9 on the right hand side:

[tex] 4n = 16 [/tex]

Now, divide both sides by 4. As before, this is needed to cancel the four on the left hand side and isolate the x, while it is just a normal division between numbers on the right:

[tex] \dfrac{4n}{4} = \dfrac{16}{4} \iff x = 4 [/tex]

Rewrite the equation in an easier way: 4n-7=9

Add 7 to both sides: 4n-7+7=9+7... 4n=16

Divide both sides by 4: 4n/4=16/4

Solution-

Clare made $160 babysitting last summer. She put the money in a saving account that pays 3% interest per year.

It is a condition of compound interest with annually compounding.

We know that,

[tex]P'=P(1+r)^n[/tex]

Where,

P' = the money she will be getting after n years,

P = the money she deposited = $160

r = annual rate of interest = 3% = 0.03

n = number of years

Money she will be getting after 1 year

[tex]\Rightarrow P'=160(1+0.03)^1=160\times 1.03=\$164.8[/tex]

This is why when she multiply 1.03 with her current amount, she gets the amount she will be getting after one year.

Money she will be getting after 2 year

Taking current balance as $164.8 as at the end of one year it will be the base amount on which interest will be calculated,

[tex]\Rightarrow P'=168.8(1+0.03)^1=168.8\times 1.03=\$169.74[/tex]

Again by multiplying 1.03 she can get the amount of money she will be getting next year.

Money she will be getting after 5 year

P' = the money she will be getting after 5 years,

P = the money she deposited = $160

r = annual rate of interest = 3% = 0.03

n = 5

Putting the values,

[tex]\Rightarrow P'=160(1+0.03)^5=160\times 1.1593=\$185.49[/tex]

She will be getting $185.49 after 5 years.

We can also do this by calculating the amount of money she will be getting at the end of each year and multiplying it with 1.03 in order to get the amount of money she will be getting the next year.

Expression for the amount of money Clare would have after 30 years if she never withdraws money from the account-

[tex]\Rightarrow P'=160(1+0.03)^30[/tex]

This is the expression for the desired condition.

The amount of money Clare would have in her account after one year is $164.80.

The amount of money Clare would have in her account after two years is $169.74

The amount of money Clare would have in her account after five years is $185.48.

The expression that can be used to determine the  amount of money Clare would have in her account after 30 years is 160(1.03^30)

The formula for calculating future value:

FV = P (1 + r)^n

Balance after one year = 160 x (1.03) = $164.80

Balance after five years = 160 x (1.03^5) = 185.48

Balance after two years = 160 x (1.03^2) = 169.74
