Answer:

Step-by-step explanation:

In this equation, the original deposit was 25 dollars. The equation shows how much total money was in the account every week. It is written in slope-intercept form, which is y=mx+b, where m is the slope (how much the account is increasing each week) and b is the y-intercept (what was in the account after 0 weeks). This means 25 dollars must be the initial deposit because it is the total before any new weekly deposits.

Answer:

i believe the answer is 25.

Step-by-step explanation:

this is because if a=how much money deposited after t= depositing weekly and 16 is being multiplied by t. that leads me to believe she deposits $16 weekly. therefore, her original deposit was $25.

tell me if this is incorrect.

This is a 30-60-90 triangle. a What is the measure of x? Х 43 X= = [ ?

Step-by-step explanation:

Hello! I hope you are having a nice day!

We can solve this problem in two steps; solving and theory.

I'll go and start off with the theory part!

Theory

We know that in geometry there are many types of triangles that have various different angles. With that, there are a few special triangles that people have made formulas for, one being a 30, 60, and 90 degree triangle.

The theorem states that the hypotenuse is $2x$ , the side opposite to 60 degrees is $x\sqrt{3}$ , and the bottom is $x$ .

Solving

We can solve this problem in a step, we just need to know what the theorem said and implement it here, since we know the values of the sides of the triangle, we can solve it by finding out the opposite side and applying the theorem rules.

If we look at the graph, we can see that the $x$ part of the side opp. of 60 degrees is 4, that means that $x$ would be double of 4, which is 8.

Therefore your answer would be: $x=8$

Cheers!

Find the value of each expression. 6b2 – 5 if b = 3

snow_tiger [21]

The answer should be 31, if I’m doing this correctly.
6(3)2-5 (multiply 6 and 3, you get 18)
18(2)-5 (multiply 18 and 2, you get 36)
36-5 (subtract 36 and 5)
31

bag contains 6 red marbles and 12 yellow marbles. If a representative sample contains 3 red marbles, then how many marbles woul

Dafna11 [192]

I think 6 because it’s a ratio

Because the yellow would always be twice as much as the red so 3x2 is 6 just like 6x2=12

You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price.

gizmo_the_mogwai [7]

Answer: The original price is $9.5
In this question, you are given the total spending( $30.40), amount of spend (4CDs) and the discounted price(80%). Then to find the original price of the CD, the calculation would be:

Total spending = amount of cd x CD discounted price
$30.40 = 4 x 0.8 Original price
3.2 Original price= $30.40
Original price= $9.5
