Stephanie and Jose both want to buy a skateboard. Stephanie has already saved $25 and plans to save $5 a week until she can buy the skateboard. Jose has $16 and plans to save $8 a week. How many weeks will it take for them to have the same amount of money and how much will they have?
(Also if u can pls type out ur answer like "10 weeks and $100" hehe)
Answer: 3 weeks and $40
Step-by-step explanation:
Let the number or weeks taken for them to have same amount be represented by x.
The information given in the question can be presented as an equation as:
Stephanie = 25 + 5x
Jose = 16 + 8x
We then equate them together
25 + 5x = 16 + 8x
25 - 16 = 8x - 5x
3x = 9
x = 9/3 = 3
The number of weeks is 3
The amount of money that they'll have will be:
= 25 + 5x
= 25 + 5(3)
= 25 + 15 = $40
Which shows a correct procedure to simplify 3V8?
Answer:
2√2
Step-by-step explanation:
If you mean 3√8, this is how you would simplify:
Know that √8=√(4*2)
Thus, √(4*2)=(√4)*(√2)=2√2
So 3√8 simplified is 2√2

5 In a scale drawing of an airplane, 1 inch equals 3 meters. The length of the actual plane is 17 meters. What is the length of the plane in the scale drawing?
Answer: 5 2/3 inches
Step-by-step explanation:
From the question, we are informed that the scale drawing of an airplane is:
1 inch = 3 meters.
Since the length of the actual plane is 17 meters, the length of the plane in the scale drawing will then be:
= 17/3
= 5 2/3 inches
a teacher wishes to keep the students books in the cardboard which is 69.9cm long,24cm wide and 36.01cm high estimate how many exercise books he can put if each exercise book is 22cm long 19.5cm wide and 0.9cm thick
Answer:
156
Step-by-step explanation:
We are given that
Length of cardboard, l=69.9 cm
Width of cardboard, b=24 cm
Height of cardboard, h=36.01 cm
Length of book, l=22 cm
Width of book, b=19.5 cm
Thickness of book, h=0.9 cm
Volume of cuboid=lbh
Using the formula
Volume of cardboard=[tex]69.9\times 24\times 36.01 cm^3[/tex]
Volume of one book=[tex]22\times 19.5\times 0.9 cm^3[/tex]
Number pf exercise book=[tex]\frac{volume\;of\;cardboard}{volume\;of;one\;book}[/tex]
Number of exercise book=[tex]\frac{69.9\times 24\times 36.01}{22\times 19.5\times 0.9}[/tex]
Number of exercise book=156

i just need the questions that are in the pics.
The function rule is a=17b and I also added a picture for the table of values in case you need it to solve the other questions.
Answer:
Step-by-step explanation:
The function is y = 17x. Then if x = 1, y = 17; if x = 2, y = 34, and so on, which agree with the table. The other questions are difficult or impossible to read. Please try to obtain and share better quality images.
HELP MEEEEEEEEEEE PLZZZZZ ITS CAMBRIDGE PAPER ill give BRANILIEST PLZZZZZZZZZZZZZZZZZZZZZZZZZZ
Answer:
a) 22 minutes
b) 9 minutes
c) 27 minutes
Step-by-step explanation:
a) Grace arrives at Stavely station at 14:30 and she wants to go to Kendal. The next train to Kendal is at 14:52 which is 22 minutes later.
52 - 30 = 22
Grace will have to wait 22 minutes for the train.
b) Since Grace is departing from the station at 14:52 the next train that reaches the station she's heading to is at 15:01.
The journey will take 9 minutes from Stavely to Kendal.
c) Sam left Windermere at 14:17 so he reaches Kendal at 14:34 and since Grace will reach at 15:01. Sam will have to wait 27 minutes until Grace arrives.
Calculations:
60 - 34 = 26
26 + 1 = 27
Sam will have to wait 27 minutes until Grace arrives.
What is the solution of the system of equations y=5.69x+25 y=9.49x+6
Given :
A system of equations y = 5.69x + 25 and y = 9.49x + 6.
To Find :
The solution of the system of equation.
Solution :
Subtracting equation 2 by 1, we get :
y - y = ( 9.49x + 6 ) - ( 5.69x + 25 )
0 = 3.8x - 19
x = 5
Putting value of x in equation 1, we get :
y = (5.69×5) + 25
y = 53.45
Therefore, the solution of the system of equations is ( 5, 53.45 ).
Use the FOIL Method to find (w+9)(w+6)
Answer:
Step-by-step explanation:
First, outside, inside, last.
w*w
6*w
9*w
9*6
[tex]w^2+15w+54[/tex]
Answer: w^2 + 15w + 54
Step-by-step explanation:
FOIL = first, outside, inside, last.
First —> multiply first numbers of each parentheses.
Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.
Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).
Last —> multiply second number of each parentheses.
(W + 9)(w + 6)
F = w^2
O = 6w
I = 9w
L = 54
W^2 + 6w + 9w + 54
W^2 +15w + 54
Write and solve a proportion to answer the question. what number a is 0.4% of 40
Answer:
.16
Step-by-step explanation:
So, we're looking for 0.4% of 40. First, let's convert 0.4% to a decimal. Since a percent is really just PARTS of one hundred, this decimal really means 0.4/100. 0.4 divided by 100 is 0.004. Next, we need to figure out how to solve this problem! To find a percent of a number, just multiply the percent (in decimal form) by the number! So, we need to answer 0.004*40, which equals 0.16.
Answer: 0.16
