5+3=4d please help me

Answers

Answer 1

Answer: $5 + 3 = 4d$

First, add '5 + 3' to get '8'.
$8 = 4d$

Second, divide both sides by '4', leaving the 'd' by itself.
$(8)/(4) = d$

Third, (8 ÷ 4), simplify the fraction to '2'.
$2 = d$

Fourth, you can switch your sides.
$d = 2$

Answer: $\fbox {d = 2}$

Answer 2

Answer: So the object of this problem is to find out the value of d.

To do this, first think about 5 + 3. This equals 8, right? So the value of d times 4 has to equal 8.

No other number besides 2 would make sense. 2 would equal d because 4 x 2 is 8, and 5 + 3 is 8.

So you would write the answer as:

5+3=4(2)

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.

At an electronics store, a $165 television is marked up 110%.

Trevor purchases the TV and must pay 6.5% sales tax.

Then the total cost of this television at the store will be

Total cost of TV = $ 165 x 1.10 x 1.065

Total cost of TV = $ 193.30

Thus, the correct option is A.

A survey of 96 students on campus showed that 29 read the Campus Observer student newspaper that morning, 24 read the news via the Internet that morning, and 20 read the local city paper that morning. Eight read the Campus Observer and the Internet news that morning, while four read the Internet news and the local paper, seven read the Campus Observer and the local city paper, and one person read the Campus Observer, the Internet news, and the local paper. (a) How many read the Internet news or local paper but not both? (b) How many read the Internet news and the local paper but not the Campus Observer? (c) How many read the Internet news or the Campus Observer or both?

Answers

Final answer:

In total, 40 students read either the Internet news or the local paper, but not both; 4 students read both the Internet news and the local paper but not the Campus Observer; and 45 students read either the Internet news, the Campus Observer, or both.

Explanation:

To answer your question, we will use the concept of sets in Mathematics and the principles of the union and intersection of sets. A Venn Diagram can be very helpful in picture this.

(a) How many read the Internet news or local paper but not both?
First, we need to find the total number of students who read either the Internet news or the local paper. This would be the number of students who read the Internet news, plus the number of students who read the local paper, minus the number of students who read both. That would be 24 + 20 - 4 = 40 students.

(b) How many read the Internet news and the local paper but not the Campus Observer?
The answer is given directly in the question. These are the students who read both the Internet news and the local paper, but did not read the Campus Observer, which is 4 students.

(c) How many read the Internet news or the Campus Observer or both?
For this, we add the number of students who read the Internet news to those who read the Campus Observer, and subtract the number of students who read both. This gives us 24 + 29 - 8 = 45 students.

Answers

Answer:

Option $\$842.13$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+(r)/(n))^(nt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=14\ years\n P=\$240\n r=0.09\nn=12$

substitute in the formula above

$A=\$240(1+(0.09)/(12))^(12*14)=\$842.13$

it is 842.13.............................
