verbal expression for c+2d

The swimming pool will contain 482 gallons of water after 6 hours.

To find out how many gallons of water the pool will contain after 6 hours, we can use the formula: Volume = initial volume + rate of change * time. In this case, the initial volume is 500 gallons, the rate of change is -3 gallons per hour, and the time is 6 hours.

Using the formula, we have: Volume = 500 + (-3 * 6) = 500 - 18 = 482 gallons.

Therefore, the pool will contain 482 gallons of water after 6 hours.

The  Statement 3: "There are exactly 30 more girls than boys". is absolutely true.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The ratio of the number of boys to the number of girls at Liam's school is 4:5 and there are 270 students at his school.

4x + 5x = 270

9x = 270

x= 30

Then, Total boys = 4(30) = 120

Total girls = 5(30) = 150

We can see that Clearly, (Number of girls) > (Number of boys)

Difference =  (Total girls) - (Total boys)

= 150-120

= 30

Hence, The  Statement 3: "There are exactly 30 more girls than boys". is absolutely true.

An expression like (3+5) × (4-1) is a combination of numbers and at least one operation. The expression can be simplified by performing the operations in the parentheses first, then applying the multiplication operation.

An expression like (3+5) × (4-1) is a combination of numbers and at least one operation. In this expression, the numbers 3, 5, 4, and 1 are combined using the addition and subtraction operations. The addition operation is represented by the symbol '+', and the subtraction operation is represented by the symbol '-'. The expression can be simplified by performing the operations in the parentheses first, then applying the multiplication operation:

(3+5) × (4-1) = 8 × 3 = 24

Answer:

12 R11 or 12 11/12

Step-by-step explanation:

Part 1: Pizza and tacos will be served on the same day again in 11 school days.

Part 2: No, pizza and tacos will not be served on the same day in 21 school days because 21 is not divisible by the LCM of 4 and 3, which is 12.

Part 1: To find the number of school days until pizza and tacos are served on the same day again, we need to find the least common multiple (LCM) of 4 and 3, which represents the cycle length for both pizza and tacos.

Find the least common multiple (LCM) of 4 and 3.

LCM(4, 3) = 12

Subtract 1 from the LCM to find the number of school days until pizza and tacos are served on the same day again.

Number of school days = LCM(4, 3) - 1

Number of school days = 12 - 1

Number of school days = 11

Therefore, pizza and tacos will be served on the same day again in 11 school days.

Part 2: To determine if pizza and tacos will be served on the same day in 21 school days, we need to check if 21 is divisible by the LCM of 4 and 3, which is 12.

Divide 21 by the LCM of 4 and 3.

21 ÷ 12 = 1, with a remainder of 9

Since the remainder is not 0, pizza and tacos will not be served on the same day in 21 school days.

Explanation: The cycle of pizza and tacos being served on the same day repeats every 12 school days (LCM of 4 and 3). If the number of school days is divisible by 12, then pizza and tacos will be served on the same day. However, since 21 is not divisible by 12 (it has a remainder of 9), pizza and tacos will not be served on the same day in 21 school days.

Complete question:

Part 1: Pizza is served in the school cafeteria every fourth school day. Tacos are served every third school day. Both pizzas and tacos are served today. In how many school days will pizza and tacos be served on the same day again? Part 2: If the pattern continues, will pizza and tacos be served on the same day in 21 school days? Explain why or why not.

Answer:

Option C is correct that is  ∠ERT and ∠MRC are vertically opposite.

Step-by-step explanation:

Vertical angles are the angles that are exactly opposite to each other in crossed lines.

Here, ∠ERT and ∠MRC are the two angles that are  vertically opposite.

Therefore, Option C is correct.  

Rest all three option A,B and D are discarded.

Answer:

Option D.

Step-by-step explanation:

The given expression is [tex](5.5\times 10^{-6})-(3.7\times 10^{-7} )[/tex]

We have to write it in the simplified form.

[tex](5.5\times 10^{-6})-(3.7\times 10^{-7} )[/tex]

= [tex](5.5\times 10^{-6})-(0.37\times 10^{-6} )[/tex]

= (5.5 - 0.37)×[tex]10^{-6}[/tex]

= 5.13×[tex]10^{-6}[/tex]

Option D will be the answer.

The annual interest rate is 6% and this can be determined by using the formula of simple interest and also by using the given data.

Given :

The formula of the simple interest can be used in order to determine the annual interest rate.

The formula of the simple interest is given by:

A = P(1 + rt)

where A is the final amount, P is the principal amount, r is the rate of interest, and t is the time in years.

Now, substitute the values of the known terms in the above formula.

520 + 156 = 520(1 + 5r)

Simplify the above expression in order to determine the value of 'r'.

676 = 520(1 + 5r)

1.3 = (1 + 5r)

0.3 = 5r

r = 0.06

Now, multiply by 100 in order to determine the percentage.

r = 0.06 [tex]\times[/tex] 100

r = 6%

So, the annual interest rate is 6%.

Answer:

[tex]\frac{1}{2^{10}}=2^{-10}[/tex]

Step-by-step explanation:

[tex]\frac{1}{1024}[/tex]

To get the expression with negative exponent , we need to convert the number 1024 in exponential form

[tex]1024= 2^5 \cdot 2^5= 2^{10}[/tex]

Replace the denominator by 2^10

[tex]\frac{1}{2^{10}}[/tex]

Now we apply exponential property

[tex]\frac{1}{a^m} =a^{-m}[/tex]

[tex]\frac{1}{2^{10}}=2^{-10}[/tex]

negative exponent other than -1 is [tex]\frac{1}{2^{10}}=2^{-10}[/tex]
