Please help me ! Thanks in advance ❤️

Step-by-step explanation:

Step one:

given data

we are told that she wants her balance to be at least $100

y=100-------1

the expression relating her current balance and spending rate is

let y be the total and m be the number of months

y=330-11m----------2

Required

the number of months m

equating 1 and 2 we have

100=330-11m

11m=330-100

11m=230

m=230/11

m=20.9

m=21 approx

This means that she will keep her account open for 1 year 9 months

First, find the converting ratio for kilometers to miles, which is

1km = 1.61 miles.

Then, divide 410 on the side for miles on the ratio.

410km=254.67miles

Therefore, 410 km is equal to 254.67 miles.

Answer:

a. The T-shirt on discount is $24.30

b. x = 0.9r

c. The regular price of the socks is $15

Step-by-step explanation:

If everything in the mall is at a 10% discount then you must multiply every regular sale by 0.9(90%). To get the regular price of the socks, you must divide by 0.9(10%).

Answer:

The best time is 56.81 seconds

Average leg time is 58.3825 seconds

Step-by-step explanation:

Here, we want to start by stating the team’s best time for the race

The team’s best time for the race is the smallest time spent on a lap

From the times given, the best time is 56.81 seconds

Now, we want to calculate the average time

We simply add up all these and divide by count

Mathematically, that will be;

(56.81 + 59.22 + 57.39 + 60.11)/4 = 58.3825 seconds

Step-by-step explanation:

add 8 to each x coordinate and divide 60 by 2 and then divide that by 2

The complete table for the given pattern is,

x: 12, 20, 28.

y: 60, 30, 15.

To complete the table for the given patterns, we can follow the specified rules for each pattern:

Pattern x: Starting number: 12, Rule: Add by 8

To generate the numbers in this pattern, we start with the given starting number, which is 12. Then, we apply the rule of adding 8 to each successive number.

12 + 8 = 20

20 + 8 = 28

So, the completed table for Pattern x would be:

x

12

20

28

Pattern Y: Starting number: 60, Rule: Divide by 2

For this pattern, we start with the given starting number, which is 60. Then, we apply the rule of dividing each successive number by 2.

60 ÷ 2 = 30

30 ÷ 2 = 15

So, the completed table for Pattern Y would be:

Y

60

30

15

By following the respective rules for each pattern, we have filled in the missing values in the table.

Answer:

We have 250 sixth-grade students are at the school

Step-by-step explanation:

Let the total number of sixth graders be represented as x

Therefore we solve the question nas shown below:

40% of x = 100 sixth grade students that prefer Hip -pop

= 40/100 × x = 100

= 40x /100 = 1000

Cross y

40x = 100 × 100

40x = 10000

x = 10000/40

x = 250 students

Hence, we have 250 sixth-grade students are at the school

Answer:

It will take 18 weeks

Step-by-step explanation:

Here, we are told that she owes a total of $81 which decreases at a rate of $4.50 per week

The number of weeks it will take to finish paying the debt will be the amount owed divided by the payment per week

Mathematically that is 81/4.5 = 18

Step-by-step explanation:

Given that:

Let the two numbers = a and b

H. C. F of the two numbers = 2

L.C.M of the two numbers = 54

If a = 27 ; b =?

The product of a and b = product of their L. C. M and H. C. F ;

HENCE ;

27 * b = 2 * 54

27b = 108

b = 108/27

b = 4

Hence, second number is 4

Answer:

$13.50

Step-by-step explanation:

Multiply the price by the discount, then subtract that number from the original price.

15.00 x 10% = $1.50

$15.00-$1.50 = $13.50

Answer:

$13.5

Step-by-step explanation:

Discount is 10%

So 15*10/100=$1.5

$15-$1.5=$13.5

Answer:

15 feets ; 45 feets ; 60 feets ; 75 feets

Step-by-step explanation:

Given that:

Moving at a constant speed ; Distance traveled in 2 seconds = 30 feets

The traveling speed = distance / time

Traveling speed = 30 feets / 2 seconds

Traveling speed = 15 ft/s

Distance traveled = traveling speed * time

Distance traveled after 1 second :

Time = 1 second

15ft/s * 1s = 15 ft

Distance traveled after 3 second :

Time = 3 second

15ft/s * 3s = 45 ft

Distance traveled after 4 second :

Time = 4 second

15ft/s * 4s = 60 ft

Distance traveled after 5 second :

Time = 5 second

15ft/s * 5s = 75 ft

Answer:

50m/s

Step-by-step explanation:

Since we are not told what to find, we can as well look for two speed of the car in meter per seconds

If the car travels at a constant speed of 100 meters per 4 seconds, the we can say;

100 meters = 4seconds

Since we want to know the speed in metres per second, we will say;

X meters = 1second

Equating both

100 meters = 4seconds

X meters = 1seconds

Cross multiply

4×X = 200×1

4X = 200

Divide both sides by 4

4X/4 = 200/4

X= 50

Hence the of the car in meter per seconds is 50meters per second

Answer:

1500 kg

Step-by-step explanation:

8 bags = 400 kg

1 bag = 400/8

= 50 kg

30 bags = 30×50

= 1500 kg

Answer:

Step-by-step explanation:

First of all, calculate the weight of 1 bag of sugar first.

400/8=50

So 1 bag of sugar is 50 Kg.

There are 30 bags of sugar so multiply 50 by 30

You will get 1,500Kg for 30 bags of sugar.

Maximum daily revenue = $2,249,600

Step-by-step explanation:

If you approach this problem with a trail and error mindset you can quickly calculate that if you take an increase of $6  per ticket or $76 per ticket, then subtract the equivalent loss of visitors which would be 800 * 3 or 2,400 then you get 29,600 visitors. By simply multiplying this number by the cost of the tickets you achive  2,249,600 daily. This could be wrong as I did not use a formula.

Answer:

see below

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi * r

176 = 2 * pi * r

Divide each side by 2 pi

176 / 2 pi = r

88/ pi = r

We can find the area by

A = pi r^2

A = pi ( 88/ pi) ^2

A =7744/pi

Letting pi = pi button

A =2464.991759 cm^2

A = 2465 cm^2

Letting pi = 3.14

A =2466.242038 cm^2

A = 2466.2 cm^2

Answer:

2463.01 cm²

Step-by-step explanation:

First, find the radius using the circumference formula:

C = 2[tex]\pi[/tex]r

176 = 2[tex]\pi[/tex]r

Divide each side by 2 pi

28 = r

Then, use the circle area formula:

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](28²)

A = 2463.01

So, the area of the circle is 2463.01 cm²
