Answer:
Terry's initial amount = £780
Step-by-step explanation:
Given that:
Ratio of Terry's money to Faye's money = 3 : 5
Let,
x be the amount of money.
Terry's amount = 3x
Faye's amount = 5x
Now,
3x + 220 = 5x - 300
220+300 = 5x - 3x
520 = 2x
2x = 520
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{520}{2}\\x=260[/tex]
Terry's initial amount = 3x = 3(260) = £780
Hence,
Terry's initial amount = £780

Step-by-step explanation:
DAY = FUN
F = (7x+2y) = 24
If DAY = FUN then D = F making (7x + 2y) = 24
This means A = U so you have to find U with 24+126=150
A triangle is 180 degrees so you would do 180-150=30
U = 30
This also makes (8x+2y) = 30
8x + 2y = 30
-8x -8x
2y = 30 - 8x
Divide everything by 2
y = 15 - 4x
Doing this you can take 7x + 2y = 24 and plug in 7x + 2(15 - 4x) = 24
Multiply it 7x + 30 - 8x = 24
Add like terms -x + 30 = 24
Subtract 30 -x = -6
Divide by -1 x = 6
Now take one of the equations and plug it in 7(6) + 2y = 24
Multiply 42 + 2y = 24
Subtract 2y = -18
Divide by 2 y = -9

If 15 larger paper clips were laid end to end to make a length of 17 7/8 inches, is each paper clip larger or smaller than one inch? Explain how you know.
Answer:
Larger than [tex]1\ \text{inch}[/tex]
Step-by-step explanation:
The total lenght of [tex]15[/tex] paper clips is [tex]17\dfrac{7}{8}=\dfrac{143}{8}\ \text{inches}[/tex]
In order to find the length of [tex]1[/tex] paper clip we divide the total length of the paper clips by [tex]15[/tex]. So,
[tex]\dfrac{\dfrac{143}{8}}{15}\\ =\dfrac{143}{8}\times\dfrac{1}{15}\\ =\dfrac{143}{120}\\ =1\dfrac{23}{120}=1.1917\ \text{inches}[/tex]
So, one paper clip is [tex]1.1917\ \text{inches}[/tex] long which is larger than [tex]1\ \text{inch}[/tex].

Which notation describes {1, 2, 3}
first three natural numbers
First, three natural numbers notation describes {1, 2, 3}.
What is set notation?In mathematics, set notation is essentially a list of numbers, things, or results. Curly brackets, often known as braces, are used for set notation. The items included between brackets are referred to as elements of a set and are not required to be in any particular order.
Given, a set {1, 2, 3}
Since a set notation used to represent the elements of a set is the curly brackets { }. An example of a set is A = {a, b, c, d}. Here the set is represented with a capital letter, and its elements are denoted by small letters.
These given number best fit in the category of natural numbers.
Therefore, First, the notation for three natural numbers shows {1, 2, 3}.

I'll use both 22/7 and 3.14 as pi, so I'll end up with two different answers. Just choose the more reliable one.
22/7 version:
22/7 * 9^2
22/7 * 81/1
1782/7
254 4/7 ft²
3.14 version:
3.14 * 9^2
3.14 * 81
314 - (3.14 * 19)
314 - 62.8 + 3.14

Answer:
1) x=30 degrees
2)y=20 degrees
1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)
2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20

Find the parallel and perpendicular slope of a line if linear equation is 7y=20(x-3) Slope (Parallel) is ____ Slope (Perpendicular) is _____
Answer:
The parallel line has slope [tex]\frac{20}{7}[/tex]
The perpendicular line has slope [tex]-\frac{7}{20}[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:
[tex]7y = 20(x-3)[/tex]
Placing it in the general format
[tex]7y = 20x - 60[/tex]
[tex]y = \frac{20x}{7} - \frac{60}{7}[/tex]
So this line has slope [tex]\frac{20}{7}[/tex]
Parallel line:
Same slope, so the parallel line has slope [tex]\frac{20}{7}[/tex]
Perpendicular line:
Multiplication of the slopes is -1. So
[tex]\frac{20m}{7} = -1[/tex]
[tex]20m = -7[/tex]
[tex]m = -\frac{7}{20}[/tex]
The perpendicular line has slope [tex]-\frac{7}{20}[/tex]

What is the equation in slope-intercept form for the line that passes
through the points (-1, 3) and (-2, -3)?
A. y = 6 - 9
C. y=-6x - 9
B. y = 6x + 9
D. y = -x + 9
Answer:
y = 6x + 9

Point-slope equation for line of slope 6 that passes through (-1,3):
y-3 = 6(x+1)
Rearrange to solve for y:
y = 6x + 9

the actual distance between two cities is 135 km. The map scale is 1cm: 100 km. Find the map distance.
someone pls helpp !!!
Answer:
1.35cm
Step-by-step explanation:
Given the scale of the map
1cm = 100km
For 135km;
x cm = 135 km
Divide both equations
1/x = 100/135
100x = 135
x = 135/100
x = 1.35cm
Hence the map distance will be 1.35cm

Janis is the set designer for a play. She has 40 feet of dividers to use to create a section in the workshop for storing props. She plans to create the space in the corner of the workshop and use the dividers to create the extra two walls. The area of the sectioned off space, A, is modeled by this equation, where x is the width of the prop section.
Which equation reveals the dimensions that will create the maximum area of the prop section?
A.
B.
C.
D.
The equation which reveals the dimensions that will create the maximum area of the prop section is;
[tex]A = - (x-20)^2 + 400[/tex]
Option D is true.
Here,
We have to find, The equation which reveals the dimensions that will create the maximum area of the prop section.
What is Dimension?
The measure of the size or distance of an object or region or space in one direction is called Dimension.
Now,
The area of the sectioned off space, A, is modeled by this equation;
[tex]A = -x^{2} + 40x[/tex]
Where, x is the width of the prop section.
Hence,
[tex]A = -x^{2} + 40x\\\\A = - (x^{2} -40x)\\\\A = - ((x - 20)^2 - 20^2)\\\\A = - ((x-20)^2 - 400)\\\\A = - (x-20)^2 + 400[/tex]
Clearly, We can say that;
A ≤ 400
So,
The equation which reveals the dimensions that will create the maximum area of the prop section is;
[tex]A = - (x-20)^2 + 400[/tex]
Option D is true.

If a number is odd, then it has a remainder of 1 when divided by 2.
Which is the conclusion of the conditional
Answer:
A number is odd
Step-by-step explanation:
Odd numbers are not completely divisible by 2.
What is the importance of knowing divisibility rules?The importance of knowing divisibility rules is that we can determine whether a number is divisible by certain numbers generally from 1 to 20 or not without actually dividing.
A number is divisible by 2 if it's unit digit is divisible by 2.
A number is divisible by 3 if the sum of the digits is divisible by 3.
A number is divisible by 4 if the last two digits is divisible by 4.
A number is divisible by 5 if its unit digit is 5 or 0.
A number is divisible by 9 if the sum of the digits is divisible by 9.
A number is divisible by 10 if its unit digit is 0.
Given, If a number is odd, then it has a remainder of 1 when divided by 2.
So the numbers which are not completely divisible by 2 have a remainder and are odd numbers and numbers which are completely divisible by 2 with no remainder are even numbers.
