Write the nunber 0.035 as a percent

3.5%
0.35%
35%
0.035%

Answers

you bring the decimal point 2 places to the right.

answer is A

We want to write the decimal number 0.035 in percent form. So, to convert this value to percent, we just multiply it by 100.
In this example multiplying 0.035 by 100, we get 3.5 (the value in percent).

Step 1: Move the decimal point two places to the right: 0.035 → 0.35 → 3.5.
Step 2: Add a % sign: 3.5%So, 0.035 is equivalent to 3.5% in percent form.
Hope this helps :)

How can you make 16 dollars using exactly and only 3 bills, one of which is not a 10-dollar bill?

Answers

That would be by using a $1 bill, a $5 bill, and a $10 bill. Either the $1 bill or the $5 bill qualify as the "one of which is not the $10 bill". It's a matter of translating the question.

Given that DF/PR=FE/RQ=3/2, what additional information is needed to prove △DEF ~ △PQR using the SSS similarity theorem?A. DE ≅ PQ
B.C. DE/EF = 3/2
D. DE/PQ = 3/2

Answers

Answer:

Option D.

Step-by-step explanation:

Given information: $(DF)/(PR)=(FE)/(RQ)=(3)/(2)$ .

We need to find the additional information which is needed to prove △DEF ~ △PQR using the SSS similarity theorem.

According to the SSS similarity theorem, two triangles are similar if their corresponding sides are proportional.

Using SSS similarity theorem, both △DEF and △PQR are similar if

$(DE)/(PQ)=(E F)/(Q R)=(DF)/(PR)$

If can be written as

$(DE)/(PQ)=(FE)/(RQ)=(DF)/(PR)$

It is given that $(DF)/(PR)=(FE)/(RQ)=(3)/(2)$ .

So, the additional information which is needed to prove △DEF ~ △PQR using the SSS similarity theorem is $(DE)/(PQ)=(3)/(2)$ .

Therefore, the correct option is D.

-4y+ 5x= 17
The point (x, -3) is a solution to the equation shown. What is the value of x?

Answers

Answer:

x = 1

Step-by-step explanation:

Given

- 4y + 5x = 17 and (x - 3) is a solution

Substitute y = - 3 into the equation and solve for x

- 4(- 3) + 5x = 17

12 + 5x = 17 ( subtract 12 from both sides )

5x = 5 ( divide both sides by 5 )

x = 1

Solution is (1, - 3 )

Answer:

x = 1
