divide £144 in the ratio 11:7
Answer:
88:56 = 11:7 pounds.
Step-by-step explanation:
Drop the pound sign. I live in Canada and I can't make that symbol. I'll add something at the end. We just want to divide 144 into a ratio of of 11:7
Step One
Add the two ratios together 11 + 7 = 18
Now set up a ratio to solve for 11 parts out of 18
11:18 = x:144 Proportion
11 / 18 = x / 144 Equation: Cross mulitiply
11*144 = 18x Combine the left side
1584 = 18x Divide by 18
1584 / 18 = x
88 = x
That is the larger amount (11 is larger than 7)
Find the smaller amount
144 - 88 = 56
The two amounts are in the ratio of 11:7
88:56 = 11:7

The shipping cost for an on-line company increases exponential based on the number of dollars the consumer has spent. It can be represented by the equation y = 0.003(2)x where x represents every $10 spent. Shipping charges will max out at $20. The company has decided that they need to add a base shipping charge of $5. What will this new function be?
Answer:
[tex]y = 5 + 0.003(2^{x})[/tex]
Step-by-step explanation:
If a base shipping charge of $ 5 is collected, it means that regardless of the amount of money spent, a base payment of $ 5 must be made for the shipment. Therefore the graph of the exponential function must move 5 units up on the positive y axis. Your new cutoff point with the positive y axis will be y = $ 5.003
Therefore, the new function that represents the shipping cost will be:
[tex]y = 5 + 0.003(2^{x})[/tex]
with [tex]x \leq 20[/tex]

z=24 degrees. To explain, you can solve for x by making the equation 2x+48=180 since 180 degrees is the angle of a straight line. Once you solve for x, you add that number to 90. Finally, subtract that number from 180 to get z. You subtract from 180 because a triangle's total angle sum is always 180

Mr.Hower can buy a computer with a down payment of 510 and 8 monthly payments of 35.75 if he pays cash for the computer the cost is 699.99 how much money will he save if he pays cash for the computer instead of paying monthly payments?
Mr. Hower will save $96.01 if he pays cash for the computer instead of making monthly payments.
Explanation:To determine how much money Mr. Hower will save if he pays cash for the computer instead of making monthly payments, we need to compare the total cost of both options.
First, let's calculate the total amount paid with monthly payments:
Down payment: $510
Monthly payments: 8 payments of $35.75
Total paid with monthly payments = Down payment + (Monthly payment amount × Number of payments)
$510 + ($35.75 × 8) = $510 + $286 = $796
Now, let's compare it to the cash price:
Cash price: $699.99
Savings if pays in cash = Total paid with monthly payments - Cash price
$796 - $699.99 = $96.01
So, Mr. Hower would save $96.01 if he pays cash for the computer instead of using the monthly payment option.

A=LWH for L
Solve the formula for the indicated variable
The given formula A=LWH, which represents the volume of a box, needs to be solved for L. This can be accomplished by dividing both sides of the equation by WH, which leads to the equation L = A / (WH).
Explanation:You have given the formula for the volume of a box, which is A=LWH. Here, A is the area, L is the length, W is the width, and H is the height. You are asked to solve this formula for L. This means we want to express L in terms of the other variables, W, H, and A.
To isolate L, you divide both sides of the equation by WH. So, the equation becomes:
L = A / (WH)
This equation shows L (length) in terms of A (area), W (width), and H (height).

At a restaurant 42 people had breakfast on Saturday morning. 1/7 ate eggs only 2/3 ate both pancakes and eggs the remaining ate pancakes only. How many people ate pancakes
Answer:
8
Step-by-step explanation:
There are 42 people who had breakfast. Each person had either egg or pancake or both.
Of these only eggs were 2/3 and both were 2/3
Hence the remaining ate only pancakes
i.e. portion of persons who ate pancakes = 1-(1/7+2/3)
= 4/21
Total no of people in the restaurant = 42
Of those people who ate eggs only= 1/7 (42) = 6
No of persons who ate both pancakes and eggs = 2/3(42) = 28
Hence no of persons who ate only pancakes =42-(6+28) = 8

the answer is: x = 1,5
Answer:
x = 1 and x = 5
Step-by-step explanation:
First we find the axis of symmetry. This will be a dotted line marking where the graph will "fold" in half. To find this we use the formula x = -b/2a:
x = -(-6)/2(1) = 6/2 = 3
We draw a dotted line at x=3, as seen in the first screenshot.
Next we find the vertex. Substitute the value of x into the related equation,
y = x²-6x+5
y = 3²-6(3)+5 = 9-18+5 = -9+5 = -4
The y-coordinate of the vertex is at -4, making the vertex (3, -4); this is seen in the second screenshot.
Next we graph the y-intercept; this is c in the equation, which in this equation is 5. This is seen in the third screenshot.
Next we reflect the y-intercept through the axis of symmetry; this is seen in the fourth screenshot.
Lastly we connect these three points with the parabola, or u-shaped graph. This is seen in the fifth screenshot.
To find the solutions, we find the x-intercepts. We can see from the fifth screenshot that these are at x=1 and x=5; these are the solutions.

Write a decimal subtraction equation that requires regrouping from the tenths. Explain how you know you will need to regroup.
Answer:
1)For example we need to find 54 -41.2
Step 1: Write down the both numbers, one under the other, with the once digit in same line.
54
-41.2
Step2: Now,add zeros so the numbers to make the same length .
54.0
-41.2
Step3: Then subtract normally, remembering to put the decimal point in the answer
54.0
-41.2
12.8
2)Here we need to subtract same place values of second number from the first number starting from right side, We can see to subtract 2 from 0 we need to take carry from 4 (4 will become 3)so that it will become 10 to subtract 2 from it ,thus we get our answer 12.8.
The decimal subtraction problem 0.72 - 0.58 requires regrouping from the tenth place. This is because you cannot subtract 8 from 2 without regrouping. The final answer, after regrouping and subtracting is 0.14.
Explanation:A decimal subtraction equation that requires regrouping from the tenths could be as follows: 0.72 - 0.58. In this problem, you cannot subtract 8 (in the hundredth place) from 2 (also in the hundredth place) without regrouping because 2 is less than 8. Therefore, you need to regroup from the tenth place.
To do this, you take one-tenth (0.10) from the tenth place, leaving you with 0.62 instead of 0.72. This action adds ten hundredths (0.10) to the hundredths place, turning our 0.02 into 0.12. Now, you can subtract 8 from 12 in the hundredth place, and you can subtract 5 from 6 in the tenth place, leaving you with the answer: 0.14.

you have $0.8 in your backpack in dimes and quarters let x represent the number of dimes and y represent the number of quarters.
A. Write an equation in standard form that represent the situation
An equation in standard form for the situation where you have $0.8 in dimes and quarters is 10x + 25y = 80, where x represents the number of dimes and y represents the number of quarters.
Explanation:To create an equation in standard form that represents the situation where you have $0.8 in your backpack in dimes and quarters, let x represent the number of dimes and y represent the number of quarters. Recall that the value of a dime is $0.10 and the value of a quarter is $0.25.
Each dime is worth $0.10, so the total value of the dimes will be 0.10x dollars. Each quarter is worth $0.25, so the total value of the quarters will be 0.25y dollars. The total amount of money is $0.8, so the equation representing this situation in standard form is:
0.10x + 0.25y = 0.8
However, to get the equation in standard form, we usually want integers as coefficients. To eliminate the decimals, we can multiply every term by 100:
10x + 25y = 80
This equation is now in standard form and represents the combination of dimes and quarters adding up to $0.8.
What is 100:25 in lowest terms
4: 1 because you could divide both sides of the ratio by 25

The equation Ax+By=10 goes through the coordinates (6,5) and (-2,-5)
What is the value of A?
What is the value of B?
The values of A and B of the given equation with the given coordinates are; A = 5 and B = -4
We are told the equation is;
Ax + By = 10
Since the equation goes through (6,5) and (-2,-5), then it means we have two simultaneous equations as;
6A + 5B = 10 ----(eq 1)
-2A - 5B = 10 ----(eq 2)
Add eq 1 to eq 2 to obtain;
4A = 20
A = 20/4
A = 5
Now, put 5 for A in eq 1 to get;
6(5) + 5B = 10
30 + 5B = 10
-5B = 30 - 10
-5B = 20
B = -20/5
B = -4
Thus, in conclusion, the values of A and B are 5 and -4 respectively.

how is the composition of function related to the order of operations
Solution:- Let f and g be the functions such that
[tex]f:X\rightarrow Y\\and\\ g:Y\rightarrow Z[/tex]
can be used to form a function which maps x in X to [tex]g(f(x))[/tex] in Z.
If z is a function of y, and y is a function of x, then z is a function of x. (transitive property)
Hence the composite function is given by
[tex]g of : X\rightarrow Z[/tex] , defined by [tex](gof)(x)=( g(f(x)) x)[/tex] for x in X.
Now , for the function g(x) into the function for f(x), we have to work from the inside out by substituting the expression. So by this way composition of function related to order of operations.
