The total amount that Fred keeps (and does not put in his savings account) is $20

Total earnings of Fred = $45

Amount spent on music = $5

Amount remaining after spending on music = $40

Fred puts half of what's left in a savings account.

Total amount put in the savings account = 40/2

Total amount put in the savings account = $20

The formula that can be used to determine the amount Scrooge would have in 4 years is: A(1 +r)^nm

A = Amount invested = $400

r = interest rate = 4/12 = 0,0333

n = number of years

m = number of compounding

$500(1.0333)^(12 x 4) = $586.60.

Answer:

x=12

Step by step explanation:

Let's solve your equation step-by-step.

2x+3=x+15

Step 1: Subtract x from both sides.

2x+3−x=x+15−x

x+3=15

Step 2: Subtract 3 from both sides.

x+3−3=15−3

x=12

=>x=12

Answer: 1 : 1.49

Step-by-step explanation:

the starting Ratio was= 79 : 53

now its 1 : ?

The first number was divided by 79 so we divide the other number by 79.

1 : 53 is now

1 : 1.49 (This is rounded to the 2d.p since the question asked for it)

Answer:

6m²-m²+5m-1

Step-by-step explanation:

Polynomial 1 = m³ + 3m² - 18m

Polynomial 2 = 23m - 4m²

Polynomial 3 = 5m³ - 1

(m³+3m²-18m)+(23m-4m²)+(5m³-1)

When adding polynomials, you'll add like terms.

(m³+5m³)+(3m²-4m²)+(-18m+23m)+(-1)

(6m³)+(-m²)+(5m)+(-1)

6m³-m²+5m-1

Answer:

CE = 7.2

Step-by-step explanation:

Area = 1/2bh

6 = 1/2 (b)(4)

6 = 2b

3 = b     b represent AB, so BC and CD is 3 unit also

Length of CE , you have a right triangle with a leg(AE) = 4 and and the other leg (AC) = 6 and the hypotenuse (CE) = x

The figure is a right triangle so you know that a² + b² = c²

4² + 6² = x²

16 + 36 = x²

52 = x²

[tex]\sqrt{52 }[/tex] = x

7.211 ≈ 7.2 = CE

Answer:

B = 0

Step-by-step explanation:

If you have y = 2x + b and are trying to get to y = 2x

Then just remove the B itself meaning it's value would be 0 so it is as if that variable was never in the actual equation.

Basing ourselves off of the formula "y = mx + b"

B = 0 would mean that the y-intercept of the line is 0

Answer:

0

Step-by-step explanation:

if y=2x and y=2x+b is the same then b must be 0.

Answer:

B

Step-by-step explanation:

Side-Angle-Side postulate (SAS)

There are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.

Two triangles are said to be congruent if their corresponding sides and angles are equal.

As per the given question,

D is the midpoint of AC, ED = FD, and angle EDA = angle FDC

In ΔAED and ΔCFD,

Side DE = Side DF

m∠EDA  = m∠FDC

Side AE= Side FC

According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.

Thus, both triangles are congruent.

Hence, there are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.
