Answer:

RS

Step-by-step explanation:

This is very similar to the previous question i answered. You can tell what sides are similar on a shape by counting how many marks they have. For example, side EF and RS have 2 marks on their sides which means they are similar.

Suppose an experiment consists of randomly drawing a marble out of a bag and replacing the marble. the bag contains 3 yellow mar

Savatey [412]

Hi there!

Since the yellow marbles to the radio of total marbles is 3/15,

3/15 = 5

We need to divide the total amount is times the marble is drawn by the ratio.

20 ÷ 5 = 4

So, the yellow marble would be drawn 4 times.

Hope this helps!

Find the 23rd term of this sequence -25,-15,-5,5....

notsponge [240]

Answer:

195

Step-by-step explanation:

To find the 23rd term of this sequence, we can use the arithmetic sequence formula $a_{n} =a_{1} +(n-1)d$ where,

$a_{n}$ = $n^{th}$ term

$a_{1}$ = first term

$n$ = term position

$d$ = common difference

$a_{23}=-25+(23-1)10$

$a_{23} =195$

Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.
