5^2 + 3^2 (equals to 34) ; That's the wrong expression

It should look like this : (5+3)^2 (which equals to 64)

John invested $4,500 at 5.5% annual simple interest. His maturity value of his investment was $5,545. How long did John invest t
mart [117]

John invested the money at simple interest for 4.22 years.

We have,

Invested amount = $ 4500

Rate of interest = 5.5 %

Time = t years

Maturity value = $ 5545

So,

Total interest earned =  $ 5545 - $ 4500 = $ 1045

And,

Simple interest = (Principal × Rate × Time ) / 100

So, Using the mentioned formula,

1045 = ( 4500 × 5.5 × t ) /100

1045 = 45 × 5.5 × t

⇒

t = (1045) / (45 × 5.5)

⇒ t = 4.22 years

Therefore, John invested the money at simple interest for 4.22 years.

Cameron is older than Hassan. Their ages are consecutive integers. Find Cameron's
Alexxandr [17]

Answer:

25

Step-by-step explanation:

So consecutive integers, just means they're separated by a value of 1. This can be generally expressed as "a, a+1" where these two values would be consecutive integers assuming "a" is an integer.

So let's express Hassan's age as the variable "x", since it's unknown. Since Cameron is older, and by definition of a consecutive integer, Cameron's can be expressed as "x+1"

So the equation we need to set up is Cameron's age + 5(Hassan's age) = 145

So we can substitute the variables we defined to express Cameron and Hassan's age: (x+1) + 5(x) = 145

Distribute the 5: x+1+5x

Add like terms: 6x+1 = 145

Subtract 1 from both sides: 6x=144

Divide both sides by 6: x=24

Since we used "x" to represent Hassan's age, Hassan's age is 24. Since we used "x+1" to represent Cameron's age, Cameron's age is "24+1" which is just 25

Reina and Sam are multiplying (8^4)^5 (7^3)^9<br><br> Is either of them correct?
PilotLPTM [1.2K]

Answer:

Sam is correct.

Step-by-step explanation:

(40 POINTS) Line m is parallel to line n. The measure of angle 4 is (9a + 28)°. The measure of angle 6 is (10a)°. What is the me
Tems11 [23]

Answer:

B. 100

Step-by-step explanation:

This is simple, the picture that is provided tells us the answer easily.

An angle lower than 90 degrees is called an acute angle. While one that is the same as 90 degrees is a right angle, and one that is more than 90 is obtuse.

We are asked to take a look at angle 4, we can see that is more than 90 degrees. Since 100 is the only answer with an amount higher than 90 degrees and fits the angle, it is the angle.
