Use rectangle ABCDIf mzBAC = (4x + 5)º and m CAD = (5x - 14)°, find m2CAD.

Answers

Answer:

m CAD is 41°

Step-by-step explanation:

The angles in a rectangle are 90 degrees each as the sides are perpendicular. A such, given that mzBAC = (4x + 5)º and m CAD = (5x - 14)°, then

4x + 5 + 5x - 14 = 90

Rearrange the equation

4x + 5x + 5 - 14 = 90

9x - 9 = 90

Collect like terms

9x = 90 + 9

9x = 99

Divide both sides by 9

x = 99/9

= 11

Recall that  m CAD = (5x - 14)°

Substitute the value of x into the expression

Hence

m CAD = (5*11 - 14)°

= (55 - 14)°

= 41°

Jessica's friend Tyshaun found an account that earns 2.5 percent interest compounded annually. Tyshaun made an initial deposit of $100 into this account at the same time Jessica made a deposit of $100 into her account. After 10 years, how much more money will Tyshaun's initial deposit have earned than Jessica's initial deposit?

Answers

Answer:

Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit

Step-by-step explanation:

As given, Jessica's initial deposit = $100

                Tyshaun initial deposit = $ 100

As given, Tyshaun account earns 2.5 percent interest compounded annually.

rate = 2.5% = 0.025

so, after t= 10 years

Payment = P[tex](1+r)^{t}[/tex] = 100[tex](1+0.025)^{10}[/tex] = 100[tex](1.025)^{10}[/tex] = 128.01

So ,

Interest = Money earned by Tayshaun - Jessica's initial deposit

            = 128.01 - 100

            = 28.01

∴ we get

Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit

20% of Aussies have blue

eyes. If 4 Aussies in a play

group have blue eyes, how

many Aussies are in the

group?


Please help

Answers

Answer:

20

Step-by-step explanation:

Step 1: 4 = 20% × Y

Step 2: 4 = 20/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:

Step 3: Y = 4 × 100/20

Step 4:Y = 4 × 100 ÷ 20

Step 5: Y = 20

The number of Aussies in the group is 20

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the total number of Aussies in the group be = A

The number of Aussies in the group who has blue eyes = 4

The percentage of Aussies that have blue eyes = 20

So , the percentage equation is

20 percentage of total number of Aussies have blue eyes = 4

And ,

( 20 / 100 ) x A = 4

Multiply by 100 on both sides , we get

20A = 400

Divide by 20 on both sides , we get

A = 20

Therefore , the value of A is 20

Hence , the total number of Aussies in the group is 20

After running for 5/6 of an hour, Konnor is 1/3 of the way through his run. How long will it take Konnor to finish his run if he continues at the same pace?

Answers

Answer:

2.5 hours  

Step-by-step explanation:

We need to find the rate at which Konnor runs. So his speed = distance/time.

Let x be his total distance. The distance covered in 5/6 of an hour is x/3. So, his speed is x/3 ÷ 5/6 = x/3 × 6/5 = 2x/5

Now, the rest of the distance left to cover is 1 - 1/3 = 2/3. So, the remaining distance is 2x/3.

The time required to cover this distance is t = 2x/3 ÷ speed = 2x/3 ÷ 2x/5 = 2x/3 × 5/2x = 5/3 of an hour.

So, the total time required for Konnor to complete his run is 5/6 + 5/3 of an hour = 5/6 + 5/3

= (5 + 10)/6

= 15/6

= 5/2 of an hour

= 2.5 hours

Solving the whole number parts

8−2=6

Solving the fraction parts

1/2−1/6=?

Find the LCD of 1/2 and 1/6 and rewrite to solve with the equivalent fractions.

LCD = 6

Step-by-step explanation:

Step 1: Define

3.6y = 1.6y + 24

Step 2: Solve for y

[Subtraction Property of Equality] Subtract 1.6y on both sides:                  2y = 24[Division Property of Equality] Divide 2 on both sides:                                y = 12

Step 3: Check

Plug in y into the original equation to verify it's a solution.

Substitute in y:                                                                                                3.6(12) = 1.6(12) + 24Multiply:                                                                                                           43.2 = 19.2 + 24Add:                                                                                                                 43.2 = 43.2
