Harry would earn total money equal to $32.50 babysitting.
Since Harry charges 50% more for each additional hour as he did for the previous hour, then
he charges 1.5 or 3/2 times as much as he did for the previous hour.
What is the charge?Term Definition Money charge refers to a special expense entry and allows an administrator to track changes in a project's billing.
Harry charges $4 for the first hour.
Harry then charges
3/2 × $4 = $6 for the second hour.
Harry then charges 3
3/2 × $6 = $9 for the third hour.
Harry then charges 3
3/2 × $9 = $ 27/2 = $13.50 for the fourth hour.
Therefore, for 4 hours of babysitting
Harry would earn $4 + $6 + $9 + $13.50 = $32.50.

The access code for a company's security system consists of four digits. Each digit can be 0 through 9. The company want to issue a different security code to each of its 200 employees. The company also has to re-issue new codes to each employee every month for security purposes. How many access codes are possible if..
Each digit can be used only once and NOT repeated?
Please help someone :(
Answer:
2 codes are possible
Step-by-step explanation:

0389
There are only 10 digits and you can only use the digits onces so the answer would be 2 codes are possible.
The number of possible codes will be 5,040.
How to get the possible codes?If each digit can be used only once, then the number of possible access codes is calculated as follows:
The first digit can be any of the 10 digits (0 through 9).
The second digit can be any of the remaining 9 digits (since one digit has already been used).
The third digit can be any of the remaining 8 digits.
The fourth digit can be any of the remaining 7 digits.
Therefore, the total number of possible access codes is:
10 x 9 x 8 x 7 = 5,040
So, there are 5,040 possible access codes if each digit can be used only once and not repeated.
Since there are 200 employees, the company has enough unique codes for each employee for 25 months. After that, the codes will have to be repeated, which may compromise the security of the system.

Which equation is y = 6x2 12x – 10 rewritten in vertex form? y = 6(x 1)2 – 11 y = 6(x 1)2 – 10 y = 6(x 1)2 – 4 y = 6(x 1)2 – 16
The vertex form of the given quadratic equation is:
[tex]y = 6*(x + 1)^2 - 16[/tex]
How to rewrite the equation in vertex form?We have the quadratic equation:
[tex]y = 6x^2 + 12x -10[/tex]
First, we need to find the vertex. The x-value of the vertex is:
h = -12/2*6 = -1
To get the y-value of the vertex, we need to evaluate the function in h, so we get:
y = 6 - 12 - 10 = -16
Then the vertex is (-1, -16)
This means that the vertex form is:
[tex]y = 6*(x + 1)^2 - 16[/tex]

There are 5 blue blocks, 7 red blocks, 2 yellow blocks, and 12 green blocks. What is the ratio of yellow blocks to total blocks?
Answer:
2:26.
Step-by-step explanation:
There are 26 blocks total, and compared to the yellow blocks, there are only two. So that would be 2:26.
Answer:
2:26
Step-by-step explanation:
A ratio is just a mathematical way to show a relationship between things. I wrote it with a colon (:), but you can write it as a fraction or words "x to b."
Most of the time in math, the order of how the question is asked doesn't matter. When it's a ratio, it does matter. Because they ask about the yellow blocks first, that has to be the first part of the ratio.
There are 2 yellow blocks.
Next, it asks for the total. That will be the other part. Add all the total blocks together: 5+7+2+12= 26.
There are 26 total blocks.
Technically, we can simplify this down to 1:13, but it's not asking to simplify it, so let's just leave it as 2:26.
You invest $500 into an account that collects 1% interest each month. If you add an additional $50 each week, what will the balance of the account be after 5 months?
Answer:
$1555.91
Step-by-step explanation:
First Month:
You start out with $500.
You add $200 in the first month, and have 700.
Multiply 700 by 1.01, to add the interest and you get 707.
Second Month:
707 + 200 = 907
907 x 1.01 = 916.07
Third Month:
916.07 + 200 = 1116.07
1116.07 x 1.01 = 1127.2307
Fourth Month:
1127.2307 + 200 = 1327.2307
1327.2307 x 1.01 = 1340.503007 (round to .50)
Fifth Month:
1340.50 + 200 = 1540.50
1540.50 x 1.01 = 1555.905
Round to 1555.905 1555.91, and there's your answer. Hope this helps!

Answer:
5.32 inches
Step-by-step explanation:
It is given that 1 inch represents 50 feet, or 1 in = 50 feet.
The actual dome is 266 feet. To find the amount of inches, divide 266 with 50:
266 total feet/50 feet per inch = 5.32 inches.
The scale model in inches, therefore, would be 5.32 inches.

a car travels at 49 km/hour how far does it travel in a 12 hour day
Answer: 2.88 km.
Step-by-step explanation:
We will discuss here how to find the distance when speed and time are given.
When speed and time are given, the distance travelled is calculated by using the formula:
Distance = Speed × Time
The unit of time in speed should be the same as that of the given time.
Solved examples to calculate distance when speed and time are given:
1. How much distance will be covered in 5 hrs at a speed of 55 km per hour?
Solution:
Distance covered in 1 hour = 55 km.
We know, Distance = Speed × Time
Distance covered in 5 hrs = 55 × 5
= 275 km.
Therefore, distance covered in 5 hrs = 275 km.
2. A bus travels at a speed of 45 km/hour. How far will it travel in 36 minutes?
Solution:
Speed = 45 km/hour
Time = 36 minutes
= 36/60 Hour (Since we know, 1 hour = 60 minutes)
= 3/5 hour
Distance = speed × time
= 45 × (3/5) km
= (45 × 3)/5 km
= 27 km.
3. How much distance will be covered in 7 hrs at a speed of 62 km per hour?
Solution:
Distance covered in 1 hour = 62 km.
We know, Distance = Speed × Time
Distance covered in 7 hrs = 62 × 7
= 434 km.
Therefore, distance covered in 7 hrs = 434 km.
4. Mike drives his car at a speed of 70 km per hour. How much distance will he cover in 3 hours 30 minutes?
Solution:
Speed of the car = 70 km/hr
Time taken = 3 hours 30 minutes
= 3 ½ hours.
Distance covered in 1 hour = 70 km
Distance covered in 3 ½ hour = 70 × 3 ½ km
= 70 × 7/2 km
= 245 km.
5. How much distance will be covered in 1 ½ hour at a speed of 32 m per minute?
Solution:
[1 ½ hr = (60 + 30) minutes = 90 minutes].
Distance covered in 1 minute = 32 metres.
Distance covered in 90 minutes = 32 × 90 = 2880 m.
We know, 1 m = 1/1000 km.
= 2880/1000 km.
= 2.88 km.

Solve the following system:
3x + 2y = 7
-4.5x - 3y = -10.5
Answer:
infinitely many solutions
Step-by-step explanation:
The system of equations :
3x + 2y = 7-4.5x - 3y = -10.5Multiplying Equation 1 times 3 and Equation 2 times 2 :
9x + 6y = 21-9x - 6y = -21Putting the equations in standard form after simplifying :
6y = -9x + 21 ⇒ y = -1.5x + 3.5-6y = 9x - 21 ⇒ y = -1.5x + 3.5As both equations are the same, the system will have infinitely many solutions.

the top of a ladder rest at a height of 20 feet against the side of the house if the base of the ladder is 7 feet from the house what is the length of the ladder
let the length of the ladder be x Using Pythagoras theorem, |hyp|^2=|opp|^2+|adj|^2
x^2=20^2+7^2
x^2= 400+49
x^2= 449
Square root of both sides:
√x^2= √449
x= 21.19ft
Thus, the length of the ladder is 21.19feet.
What is size of
angle p?°
Answer:
A) 75°
Step-by-step explanation:
It is the property of a polygon that the sum of the external angles is equal to 360°.
===============================================================
Solving :
⇒ p + 55 + 30 + 75 + 55 + 70 = 360
⇒ p + 85 + 130 + 70 = 360
⇒ p + 285 = 360
⇒ p = 360 - 285
⇒ ∠p = 75°
Answer :
A) 75°
because the property of polygon is equal to 360° the sum of external angles.
