Answer:

2/9

Step-by-step explanation:

Caroline gets 1/9 of the money, so the 8/9 remaining is split 1:3 between Colin and Sarah. Colin gets 1/4 of the remaining money then.

1/4 * 8/9 = 8/36= 2/9

Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?

Answers

Answer:

25 grams

Step-by-step explanation:

Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?

From the above question:

1 penny = 2.5 grams

10 pennies = x grams

Cross Multiply

1 × x grams = 10 pennies × 2.5 grams

x grams = 25 grams.

Hence, the weight of 10 pennies is 25 grams

Step-by-step explanation:

In this problem, you can use the Pythagorean Theorem to find the hypotenuse, which is x. The formula for the Pythagorean Theorem is:  [tex]a^{2} +b^{2}=c^{2}[/tex], where a and b are the two lengths of the triangle, and c is the hypotenuse (which is x).

Steps:

-We know the two sides already, which are 15 and 8, so we can substitute a and b into the equation:  [tex]15^{2} +8^{2}=c^{2}[/tex]  (the c is the same as x, just letting you know)

-Then, simplify the equation to get:  [tex]225+64=x^{2}[/tex] (I replaced c with x just so you can understand better that we are trying to find x, the hypotenuse)

-Add the 225 and 64 to get:  [tex]289=x^{2}[/tex]

-Find the square root of both sides to get x by itself:  [tex]\sqrt{289}=\sqrt{x^{2}[/tex]

-Evaluate the equation to get:  [tex]\sqrt{289} =x[/tex] which simplifies to [tex]17=x[/tex]

Answer: 17

Samantha was training to play basketball. She threw the ball 19 times. Gabrielle wrote down all Samantha's throws and for all the ones who got in the basket she added 5 points. For all the throws that weren't successful, she got rid of 3 points. At the end Samantha got 55 points. How many times did Samantha throw the ball in the basket successfully?

Answers

Answer:

15 times.

Step-by-step explanation:

5 x 14 = 70 points

3 x (19-14) = 3 x 5 = 15 points

70 points - 15 points = 55 points.

find the perimeter of the shaded figure.

Answers

Answer:

38

Step-by-step explanation:

Count the unit squares for each side, starting from the left it's 7, 10, 7, 2, 2, 6, 2, and 2

Now add them together:

7 + 10 + 7 + 2 + 2 + 6 + 2 + 2 = 17 + 9 + 8 + 4 = 26 + 12 = 38

Answer: 38 units

Step-by-step explanation: Perimeter is asking for the total length of all the sides that make up a figure. The top border is 10 units, the two outer sides are 7 each (14 in total), if you add all the downward facing edges you get another 10 units, and the two inside sides are 2 units each (4 in total).

10+14+10+4 = 38

Mr. Smith is 81 years older than his grandson, Victor. In 3 years, Mr. Smith will be four times as old as Victor. How old is Victor now?

A) 21 years old

B) 22 years old

C) 24 years old

D) 27 years old

Answers

I’m sure it’s 26 but I can’t find the answer here
Let the age of Victor be x and the age of Mr Smith will be x+81

After 3 years 4(x+3)= x+81+3

4x+12= x +84

4x-x= 84–12= 72

3x = 72. Or x = 24

Now Victor's age is 24 and Mr. Smith is 105

In three years Victor will be 27and Mr. Smith will be 108 (four times of 27)
