Can you solve this:
JUST number 7 and 8
Thanks everyone

Answers

Answer 1

Answer: for number 7 because 9 is the number of small triangle and 99 is for the bigger one so you can say 9 * 11 = 99 so 10 * 11 = 110 = x
and for number 8 because the small triangle has the same sides so the bigger one should have too so x = 100 :)))
hope this is helpful
have a nice day

How can I change 19/4 in a mixed number

Answers

19/4 can also be written as 16/4+3/4 so the mixed fraction will be 4+3/4...in other words 4 3/4. And to check it, you can multiply the denominator (here, 4) by the whole number(here, 4) and then add the numerator(here, 3)
Which adds up to 19/4! :)

The improper fraction 19/4, can be changed into a mixed number as: 19/4 = 4¾.

How to Change an Improper Fraction to a Mixed Number?

A mixed number is a combination of a whole number and a proper fraction.

To change the improper fraction 19/4 into a mixed number, follow these steps:

Step 1: Divide the numerator (19) by the denominator (4).

19 ÷ 4 = 4 with a remainder of 3.

Step 2: Write down the whole number part (the quotient) and the remainder as a fraction.

The quotient is 4, and the remainder is 3. So we have: 4¾.

Therefore, 19/4 as a mixed number is 4¾.

Suppose you earn $6 per hour at your part-time job.What will your new hourly rate be after a 2.5% raise? Explain.

Answers

The new hourly rate after a 2.5% raise will be $6.15.

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 ‘%’ is used to symbolize it.

Suppose you earn $6 per hour at your part-time job. The new hourly rate is after a 2.5% raise.

Let x be the new hourly rate. Then the equation is given as,

x = $6 x (1 + 2.5%)

x = $6 x (1 + 0.025)

x = $6 x 1.025

x = $6.15

The new hourly rate after a 2.5% raise will be $6.15.

First change 2.5% to a decimal by dividing by 100. 2.5÷100=0.025. Then multiply 6 by 0.025. 6×0.025=0.15. Finally add 0.15 to 6 for the answer. 6+0.15=6.15.
So the answer is $6.15.

a and b are vectors such that |a| = √3, |b| = 1, and the angle between them is 5π/6. Using scalar product, find the exact value of |2a + b|.

Answers

Answer:

|2a + b| = 2√(3) + 1

Step-by-step explanation:

|a| = √(3)

|b| = 1

θ = 5π/6

For scalar vectors, A.B = |a|.|b|.cosθ

|2a| = 2*√(3) = 2√(3)

|2a + b| = 2√(3) + 1

Since we don't have to find the scalar or dot product, there's no need to use the formula requiring the angle between them

|2a + b| = 2√(3) + 1
