Answer:
4 weeks, Jose and Martin will have the same amount of money in 4 weeks which is $150 each
Step-by-step explanation:
Jose:
y = -25x +250
Martin:
y=30x+30
Substitute x= 6 into the two equations
Jose:
y = -25(6) + 250
= -150+250
y = 100
Martin:
y = 30(6) +30
=180+30
y = 2100
Substitute x=4 into the two equations
Jose:
y = -25(4) + 250
=-100+250
y = 150
Martin:
y = 30(4) + 30
=120+30
y = 150
A new phone costs $450. There is a 40% discount on the price of the phone and an 8% sales tax on the discount price. What is the final cost of the phone after the discount and the sales tax?
Answer:
291.60 is the final cost
Step-by-step explanation:
First find the cost of the phone before tax
Discount
450*.40
180
Price after discount
450-180
270
Now find the tax
270* 8%
270 *.08
21.60
Add this to the price after discount
270+21.60
291.60
Answer:
291.60
Step-by-step explanation:
40% of 450 is 270 and 8% of 270 is 21.6 so add 21.6 to 270 and you get 291.60

work out ⅕ of 80
work out 48÷½
❤︎シ︎✌︎
Step-by-step explanation:
1/5×80=80/5=16 because 1/5 out of 80 means to multiply 1/5 by 8o so the answer to that question is 16.
48÷1/2=48×2/1=96/1=96 because when you divide a fraction by fraction or a fraction with a number there is a rule that says you have to reverse the fraction on the right side and replace the division sign to a multiply sign and multiply. so the answer becomes 482)×2/1 which equals 96.
Find the 12th term of the geometric sequence 8, 16, 32, ...
Answer:
Step-by-step explanation:
\[a_{n}=a{1}r^{n-1}\]
r=16/8=2
a_{12}=8(2)^{12-1}
[tex]a_{12}=8(2)^{11}=16384[/tex]
The 12th term of the geometric sequence is 16384.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same common ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, a geometric sequence 8, 16, 32,... which has a common ratio(r)
= 16/8 and first term a₁ = 8.
We know nth term of a geometric sequence is aₙ = a₁rⁿ⁻¹.
∴ 12t term of the geometric sequence is a₁₂ = 8.2¹²⁻¹
= 8.2¹¹.
= 8.2048.
= 16384.

Compare the mean of the prices of Felix's books and of Tyler's books. What do the differences in the means tell you about the prices of the two sets of books?
Felix Mean: 10.21
Tyler Mean: 77.36
Answer:
It tells you 2 different things
Step-by-step explanation:
1. It could tell you that Tyler's book is much more expensive than Felix's.
2. It could tell you that they're the same price but Tyler sold more.
Answer:
The means are very different, so almost all of Tyler's books are more expensive than Felix's books.

The sea turtle habitat at the zoo is made by connecting two large aquariums. The first aquarium is 6 m long, 4 m wide, and 2 m high The second aquarium is 8 m long 9 m wide and 3 m high how many cubic meters of space do the sea turtles have in their habitat
Answer:
264 cubic metres
Step-by-step explanation:
We need to find the volume of both aquariums and add them up.
The aquariums are shaped as rectangular prisms.
The volume of a rectangular prism is:
V = L * W * H
where L = length, W = width, H = height
The first aquarium is 6 m long, 4 m wide, and 2 m high. Its volume is:
V = 6 * 4 * 2 = 48 cubic metres
The second aquarium is 8 m long, 9 m wide and 3 m high. Its volume is:
V = 8 * 9 * 3 = 216 cubic metres
The amount of space the turtles have is therefore:
V = 48 + 216 = 264 cubic metres

in a class of 60 student, the number of student who passed biology is 6 more than the number who passed chemistry every student passed both at least one of the two subjects and 8 student passed both subject
Firstly we need to find how many students passed chemistry or biology
60-8=52 studdnts passed biology or chemistry
Let number of students who passed chemistry is x, than number of students who passed biology is 52-x.
[tex]52 - x - x = 6 \\ - 2x = - 46 \\ x = 23[/tex]
So, 23 students passed chemistry, than
23+6=29 students passed biology
Answer: 23 students passed chemistry and 29 students passed biology
Answer:
23 students passed chemistry and 29 students passed biology

An equilateral triangle has a side length of 7 cm. If a perpendicular is dropped from a corner, what is the length of the perpendicular?
Answer:
6.06cm
Step-by-step explanation:
An equilateral triangle is a triangle that has all its sides equal. If the given equilateral triangle has a side length of 7 cm, then all its sides are 7cm each. To get the length of the perpendicular dropped from a corner. we will use the Pythagoras theorem.
According to the theorem,
hyp² = opp²+adj²
Lets take the height as the opposite side of one of the right angled triangle as shown in the attachment.
hyp = 7cm and adj = 7/2 = 3.5cm
opp² = 7² - 3.5²
opp² = 49 - 12.25
Opp = √36.75
Opp = 6.06cm
This shows that the length of the perpendicular is 6.06m
Jose's ball is stuck on the roof of his home, which is 8 feet high. He wants to use a ladder to climb up and get his ball. If he sets the base of the ladder 6 feet away from his home, what is the minimum length that the ladder can be? Explain how you solved this question using context and at least three sentences. Hint: Draw your the scenario and label given values.
Answer:
10 feet
Step-by-step explanation:
It becomes a right-angled triangle with height of 8feet and base of 6feet.
Using Pythagoras theorem:
a² = b² + c²
a² = 8² + 6²
a² = 64 + 36
a² = 100
a = √100
a = 10
A game comes with a deck of cards with each card showing one of the numbers 2,3,4,5,6, or 8. Each card occurs one time in red and one time in purple, and one time in blue. Given that a blue card is drawn what is the probability the card is 4
Answer:
0.1667 = 16.67%.
Step-by-step explanation:
We already know that the card drawn is blue, so now we need to check the value of the card.
The blue cards have 6 possibilities of values (2, 3, 4, 5, 6 or 8), and the number 4 appears only 1 time, so the probability of the blue card having the value 4 is the number of times this value occurs by the number of possible values:
P = 1/6 = 0.1667 = 16.67%.
The garden has an area of 28 square meters. The length of the garden is 7 meters. What is the width of the garden?
You have to find the width
Answer:
The answer is 4
Step-by-step explanation:
Since the total area is 28, and the length is 7. Therefore 28 divided by 7 equals 4.
Hope this helps
Answer:
4 meters
Step-by-step explanation:
Let's assume this is a rectangular garden.
The area of a rectangle can be found using:
a=l*w
We know the area is 28 square meters and the length is 7 meters. We can substitute 28 in for a, and 7 in for l.
28=7*w
Now we need to solve for w. To solve, we have to get w by itself. 7 and w are being multiplied. To reverse this, divide both sides by 7.
28/7=7*w/7
28/7=w
4=w
The width is 4 meters
