julio has 13 red marbles 4 blue mables and 8 yellow marbles julio draws a marble out of the bag 100 times how many time out of 1
Keith_Richards [23]

Answer:

16 times

Step-by-step explanation:

13 + 4 +8 = 25 total marbles

(4 is total number of blue marbles, 25 is complete total of marbles)

4/25 times =   ?/100 times

Because 25 times 4 is equal to 100, you then multiply 4 by 4 to get 16

16/100 times

Solve for x. 3x/2 = 15 x = 22 1/2 x = 10 1/2 x = 10 x = 1/10
Leokris [45]

Answer:

x = 10

Step-by-step explanation:

(3x)/2 = 15 is your question.

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponent (& roots), Multiplication, Division, Addition, Subtraction).

First, multiply 2 to both sides

((3x)/2) = (15)(2)

3x = (15)(2)

3x = 30

Next, to isolate the variable (x), divide 3 from both sides

(3x)/3 = (30)/3

x = 30/3

x = 10

x = 10 is your answer

Colin invests £2200 into his bank account. He receives 2.5% per year simple interest. How much will Colin have after 3 years? Gi
Helga [31]

<u>Answer:</u>

  • Colin will have $2365 after 3 years.

<u>Step-by-step explanation:</u>

<u>Using PRT/100, we can find the interest and then sum it up with the principle amount.</u>

  • => 2200 x 2.5 x 3/100 = Interest
  • => 22 x 2.5 x 3 = Interest
  • => 55 x 3 = Interest
  • => 165 = Interest
  • => 2200 + 165 = Total amount
  • => $2365

Hence, <u>Colin will have $2365 after 3 years.</u>

Hoped this helped.

Name the types of angles shown?
Nataly [62]

Answer: B and C

Step-by-step explanation:

Let's start off with some definitions.

Supplementary Angles: Two angles that add up to 180°.

Right Angle: One angle equal to 90°. Also identified with a square on the angle.

Complementary Angles: Two angles that add up to 90°.

Straight Angle: A straight line, which equals to 180°.

Right off the bad, we can knock off A and D because there is no proof of those being seen.

The angle <EFH is a right angle because it is equal to 90°. If you pay close attention, the angles <EFG and <GFH both add up to 90°, making them complementary angles.

Therefore, the correct answers are <u>B and C.</u>

I hope this helps! Pls mark brainliest!! :)
