write 25 less than a number 4 as an expression​

Answers

Answer 1

Answer:

y - 25 = 4

Step-by-step explanation:

i’m guessing you meant this as “25 less than a number = 4.” so i can put tha as an expression.

Basically you’re gonna want to take the unknown number and turn it into a variable.

You should know what a variable is but if not it’s just a letter in place for an unknown number.

so since the unknown number, we will use the letter y as the variable.

so y-25=4

boom that’s it.

since there’s an unknown number in place of the bigger number, we can just put the variable and write the rest out as a regular problem.

and if you need to know the variable number it’s 29.

0.74 units

1.17 units

1.64 units

2.14 units

Answers

Answer:

1.17

Step-by-step explanation:

(MUCH BETTER!)

From the definition of the sin of an angle, you know:

sin(45°) = AC/AB = 4/AB   ⇒   AB = 4/sin(45°) ≈ 5.6569

sin(63°) = AC/AD = 4/AD   ⇒   AD = 4/sin(63°) ≈ 4.4893

Then the difference AB-AD is:

AB -AD = 5.6569 -4.4893 = 1.1676

AB -AD ≈ 1.17 units

y=-¼(0)+2y=2

therefore y intercept is 0

let's substitute y to 0 to find x intercept

0=(-¼)x+2(-¼)x=-2x=-2×-4x=8

therefore

x intercept is 8

write 34 as a product of its prime factors. PLEASE HELP I NEED TO TURN IT IN IN % MINUTES

Answers

Answer: Down below

Step-by-step explanation: First of all, as 34 is an even number, so it must be divisible by smallest prime 2.

Thus, 2 must be a factor of 34.

Now, look for number obtained on dividing 34 by 2 i.e.

34÷2=17.  

So, 17 is our new number.

Now, look for factors/divisors of 17, which are precisely 1 and 17 i.e. 17 is itself a prime.

This implies only factors possible for 34 are 2 and 17.

Thus ,34 can be written as product of prime numbers 2 and 17 as  34=2×17.  

Key idea. Given any number, divide it by smallest divisible prime and look for the number obtained on division.

Now, repeat the process for the number obtained.

If no division by a smaller prime than that number is possible, then our number is itself a prime.

Your cousin borrows $1125 to repair her car. The simple annual interest rate is 10%. She makes equal monthly payments of $25. How many years will it take to pay off the loan?

Answers

Answer:

26 months i believe is correct :)

Step-by-step explanation:

The number of years it will take to pay off the loan will be  4.125 years based on simple interest.

What is simple interest?

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

As per the given,

Total loan = $1125

Rate of interest R = 10%

Monthly payment = $25

Yearly payment = 25 x 12 =$300

Suppose it takes T years,

Total amount A = principle P + interest

A = 1125 + 10% of 1125

A = 1125 + 0.10 x 1125

A = $1237.5

The number of years it will take will be as follows,

Total amount / yearly payment

⇒ 1237.5/300

⇒ 4.125 years.

Hence"The number of years it will take to pay off the loan will be  4.125 years based on simple interest".

The trapezoid below has been enlarged by a scale of 1.5. What is the area of the enlarged trapezoid?

Answers

Answer:

New area by scale of 1.5 = 81 in²

Step-by-step explanation:

Given:

Current area  = 36 in²

Find:

New area by scale of 1.5

Computation:

New area by scale of 1.5 = Current area x (scale factor)²

New area by scale of 1.5 = 36 x (1.5)²

New area by scale of 1.5 = 36 x (2.25)

New area by scale of 1.5 = 81 in²

Answer:

B.

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.

We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

Therefore, the area of the enlarged trapezoid would be  and option B is the correct choice.
