Which options could be the next step in simplifying this expression? (18 + 23) + 7 Choose exactly two answers that are correct.
A. 18 + 30 (use the associative property)
B. 41 + 7 (use order of operations)
C. 30 + 25 (use the commutative property)
D. 25 + 30 (use the distributive property)

Answers

Answer 1

Answer: In adding, subtracting, multiplying anddividing numbers, always remember this rule: PMDAS (or parenthesis, multiply,divide, add, subtract). The P in PMDAS must come first. We must use an order ofoperations. In the problem given, (18 + 23) + 7, they must be added. However you have aparenthesis that has the numbers 18 and 23. You will add 18 and 23 first and then you will get 41. And so the answer is 41 + 7,letter B.

How to find the measurement of a parallelogram

Answers

Answer:

In a parallelogram, consecutive angles are supplementary. Thus,

B + C = 180^{\circ}

(2x+15)+x=180

3x+15=180

3x=165

x=55

Step-by-step explanation:

A half of a class and a half of a student got A on a test. If yet another student got an A, then two-thirds of the class would have an A for the test! How many students are there in that class?

Answers

Answer:

6 students.

Step-by-step explanation:

let the number of students in class be x

Since Half of the class represents half of the students, therefore

Number of student who got A in test = $(x)/(2)$

Now if one more student got A in test then the number of students who got A in test will be $(x)/(2) +1$

Now according to equation,

$(2x)/(3) = (x)/(2) +1$

$(2x)/(3) - (x)/(2) = 1$

Further solving

$(4x-3x)/(6) = 1$

$x = 6$

Hence the total number of students in class is 6.

Step-by-step explanation:

1/2x+2/3=2/3x

2/3=4/6x-3/6x=1/6x

If $535 is invested at an interest rate of 6% per year and is compounded continuously, how much will the investment be worth in 10 years?$1307.12
$974.83
$973.38
$403.43

Answers

A = Pe^rt , e = 2.718

A = 535 * (2.718)^(10 * 0.06)
A = 974.83

answer is $974.83

Compound Interest can be defined as the interest that is accumulated on a particular sum of money or investment after a given period of time.

The investment will be worth $974.83 in 10 years.

The formula to solve for the amount an investment will be worth if it is compounded continuously is given as:

A = Pe^rt

P = Principal = $535

R = Interest rate = 10%

T = Time in years = 10 years

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 rate per year,

Then solve the equation for A

A = Pe^rt

A = 535(2.71828)^(0.06 x10)

A = $974.83

Therefore, the investment will be worth $974.83 in 10 years.
