jack and bob leave their houses at 10:00 am walking toward each other. they meet at 10:30 am. if their houses are 7km apart, and jack is walking at 8 km/h , find bobs rate
URGENT
Bob is walking at the rate of 6 kilometer per hours
Jack and Bob leave their houses at 10:00 am walking toward each other and they meet at 10.30 am.
The distance between two houses = 7 kilometer
The speed of the Jack = 8 kilometer per hour
The distance traveled by Jack in 30 minutes = 8 / 2
= 4 kilometer
The remaining distance = 7 - 4
= 3 kilometer
Bob traveled 3 kilometers in 30 minutes
Then the speed of the Bob = 3 × 2
= 6 kilometer per hour
Hence, the Bob is walking at the rate of 6 kilometer per hours

the number of people infected with coronavirus doubles every 3.3 days. how many days does it take for the u.s. to go from one case (patient zero) to all 330,000,000 americans being infected.
It will take 96.7 days for the whole US population to get infected.
Given information;
The number of people infected with coronavirus doubles every 3.3 days as following;
1 → 2 → 4 → 8 → 16 → 32 → 64 → . . . . . . . . . . . . → 333,000,000
Let 'x' denotes number of 3.3 days passed the for cases 333,000,000.
⇒ [tex]2^x = 333,000,000[/tex]
For the above equation applying log on both sides. we get;
x(In 2) = In (330,000,000)
x = In (330,000,000)/(In 2)
x = 28.3
Therefore;
So, total no. of 3.3 days passed = 1 + x
= 1 + 28.3
= 29.3
And number of days for 1 to 330,000,000 = 29.3 * 3.3 days
= 96.7 days
Hence, it will take 96.7 days to infect the total population in US.

A line has the equation y - 4 = 3x + 11 Work out the gradient and the y-intercept of the line.
Answer: Gradient is 3 and y-intercept is 15
Step-by-step explanation:
by rearranging the equation so y is on 1 side we get:
y = 3x + 15
the gradient is the number before the x (coefficient)
the y intercept is the number that is not multiplied by the x, in this case 15

Nelson’s birthday party will be at the skating rink. The cost for each person is $ 25 . The cost of the room for the party is $ 50 . The function C ( x ) = 25 x + 50 models the total cost, C , where x is the number of people at the party. What is the maximum number of people who can be at the party for a budget of $ 600 ?
Answer:
24 people
Step-by-step explanation:
600 = 25x + 50 Subtract 50 from both sides of the equation
550 = 25x Divide both sides by 25
24 = x
Answer: x = 22
Step-by-step explanation:
We need to use trial and error for this.
20 - 25 seems like a reasonable range to substitute x with.
C(20) = 25(20) + 50
C(20) = 500 + 50
C(20) = 550.
This means that 20 is not the answer. Let's try 21.
C(21) = 25(21) + 50
C(21) = 525 + 50
C(21) = 575.
This means that 21 is also not the answer. let's try 22.
C(22) = 25(22) + 50
C(22) = 550 + 50
C(22) = 600.
This means that 22 is the maximum number of people for a budget of $600.

Betsie wants to buy the envelopes for the best possible price
Which shop should Betsie buy the 250 envelopes from?
You must show how you got your answer.
At Letter2go, Betsie can purchase the 250 envelopes. As an example, 250 envelopes cost £31.9 in the Letter2go store but £33.17 in the Value World store.
What is an Expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.
From Letters 2 go:
Pack of 25 envelopes for £3.19
If we look at the price of envelopes at shop 1, which is Value World,
The cost of a pack of 10 envelopes is £1.99.
Also, buy 2, get one is free
Which means that 1 pack = £1.99
2 packs = 2×£1.99 = £3.98
Also, with 2 packs Betsie get 1 pack free
So, Betsie gets 3 packs for £3.98.
1 pack = 10 envelopes
3 packs = 30 envelopes.
Hence,
In shop Value World:
30 envelopes = £3.98
1 envelope = £3.98/30
250 envelopes = (3.98/30)×250
So, 250 envelopes will cost £33.17 in Shop Value World.
From shop Letter 2 go:
25 envelopes = £3.19
1 envelope = £3.19/25
250 envelopes = (3.19/25)×250
Therefore, 250 envelopes in Store Letter 2 go should cost £31.9.

Step-by-step explanation:
so in y=mx+b form.
m=slope b=y-int
Subtract 5 from both sides to isolate y on a side.
4x-6=3y

Option (3) is correct. A translation of 3 units down.
What is translation of points?
A point's linear displacement from its starting position is referred to as translation. In an x - y coordinate plane, a point's coordinates are labelled with respect to the origin by first indicating the horizontal position and then the vertical position.
Given: The coordinates of Quadrilateral EFGH and its image, Quadrilateral E'F'G'H', are given below,

F(-3, 4) ⇒ F'(-3, 1)
G(-2, 1) ⇒ G'(-2, -2)
H(-4, 2) ⇒ H'(-4, -1)
From above we can see that the y - coordinate of each point is decrease by 3.
Which is the translation of 3 units down.

What number needs to be added to this set of numbers so the mean is 6? {3,4,7}
The finalized set is { 3 , 4 ,7 , 10 }
How is mean calculated ?Only numerical variables, whether continuous or discrete, can be used to calculate the mean. It is calculated by merely dividing the total number of values in a data set by the sum of all the values in the data set.
The given set is {3,4,7}
3 + 4 + 7 =14
To calculate the mean we divide the sum by the number of numbers present
So we must add 10
because if we add 10 to the set we get
3 + 4 + 7 + 10= 24
Thus the mean = [tex]\frac{24}{4}[/tex]
When we divide these two numbers we get :
mean = 6

Nachelle has a points card for a movie theater.
She receives 50 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs at least 170 points for a free movie ticket.
Write and solve an inequality which can be used to determine vv, the number of visits Nachelle can make to earn her first free movie ticket.
Step-by-step explanation:
#=number
Identify what is in the inequalityNachelle gets 50 points when signing up: 50+#x=#
Nachelle earns 12.5 points for each visit: 50+12.5x=#
Nachelle need at least 170 points: 50+12.5x=170
Now you have your inequality, solve.Subtract 50 from both sides: 50-50+12.5x=170-50
50-50 cancel out so now your left with 12.5x=170-50
Subtract the 170 and 50: 12.5x=120
Divide 12.5 from both sides: 12.5x÷12.5=120÷12.5
12.5x÷12.5 cancel out so the inequality is now x=120÷12.5
Divide 120 and 12.5: x=9.6
Since there is no such thing as 9.6 visits, round to 10.

. A bag of marbles contains a ratio of 4 red marbles to 13 more blue marbles than
red marbles. If there are 51 blue marbles, how many red marbles are in the
bag?
The number of red marbles in the bag is 12.
We are given a bag. The bag contains two types of marbles. There are red and blue marbles in the bag. The ratio of marbles is four red marbles to thirteen more blue marbles than red marbles. Let the ratio of the number of red marbles to that of blue marbles be denoted by the variable "r".
r = 4/(13 + 4) = 4/17
The number of red marbles and blue marbles in the bag is 4x and 17x, respectively, where "x" is a variable. We know that the number of blue marbles in the bag is 51. We can write the following equation to find the value of "x".
17*x = 51
x = 51/17 = 3
Hence, the number of red marbles is 4x = 4*3 = 12.
