Answers

Answer 1

Answer:

[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

Step-by-step explanation:

Given

[tex]Backpack = 18\frac{7}{9}kg[/tex] --- with math book

[tex]Backpack = 14\frac{7}{8}kg[/tex] --- without math book

Required

Determine the weight of her math book

To do this, we simply calculate the difference in the weights given.

Math Book= Backpack(with math book) - Backpack (without math book)

[tex]Math\ Book = 18\frac{7}{9} - 14\frac{7}{8}[/tex]

[tex]Math\ Book = \frac{169}{9} - \frac{119}{8}[/tex]

Take LCM

[tex]Math\ Book = \frac{8 * 169 - 9 * 119}{72}[/tex]

[tex]Math\ Book = \frac{1352 - 1071}{72}[/tex]

[tex]Math\ Book = \frac{281}{72}[/tex]

[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

Answers

Answer:

Linear

Step-by-step explanation:

The y is increasing constantly by 5 each time. The equation that would represent this is y=5x-7 because when x is 0 y is -7, so that is your y intercept, and the m, or slope, of your graph is 5, because of the constantly increasing y.

The given  table is representing linear function. So Option B is correct.

What are functions?

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Given that,

A table

x   0    1    2    3    4    5  

y   -3   5   13  21   29  37

Lets us first check that data for linear relationship,

Consider a function,

y = mx + c

lets put value (0, -3)

-3  = m0 + c

c = -3

y = mx -3

Now putting second point

5 = mx1 -3

m = 8

y = 8x - 3

If third point satisfies the given condition

then it will be linear function

x = 2 & y = 13

y = 8x -3

13 = 8x2 - 3

13 = 13

hence proved

Thus, the given table represents the linear function.

There are 2 friends chasing one another. They are 80
feet apart. Caroline is chasing after Sam. Sam runs at
a speed of 22 feet per second and Caroline runs at a
speed of 31 feet per second. How many seconds will it
take for Caroline to catch Sam?

Answers

Answer:

8.9 seconds

Step-by-step explanation:

When caroline catches sam after some time lets say t

distance moved by Caroline will be 80 feet more than sam as they were 80 feet apart.

Given

Let the time taken by Caroline to catch sam is t seconds

distance covered by Caroline in t seconds = speed of caroline*t

distance covered by Caroline in t seconds = 31  * t

distance covered by Caroline in t seconds = 31t feet

distance covered by sam in t seconds = speed of sam*t

distance covered by sam in t seconds = 22  * t

distance covered by sam in t seconds = 22t feet

distance moved by Caroline will be 80 feet more than sam as they were 80 feet apart and caroline catches her in t seconds

thus,

distance covered by Caroline in t seconds  = distance covered by sam in t seconds  + 80 feet

31t = 22t + 80

subtracting 22t from both sides

=> 31t - 22 t = 80

=> 9t = 80

=>t = 80/9 = 8.9 seconds

Thus,

it will take 8.9 seconds for Caroline to catch Sam

▪ Answer:

▪ Step-by-step explanation:

Hi there !

opposite angles

4x + 2 = 7x - 25

2 + 25 = 7x - 4x

27 = 3x

x = 27 ÷ 3

x = 9

Good luck !

Answer:

x = 9

Step-by-step explanation:

opposite angles

4x + 2 = 7x - 25

2 + 25 = 7x - 4x

27 = 3x

x = 27 ÷ 3

Write an equation of the line that passes through the point (6, 3) and is perpendicular to y=-1/3x+ 12.
y=3x+12
y=x+5
y=-1/3x+5
y=-1/3x+12

Answers

Answer:

A: [tex]y=3x+12[/tex]

Step-by-step explanation:

To start we need to know what makes lines perpendicular. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.

Then, we need to understand the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. We also know that [tex]x[/tex] and [tex]y[/tex] represent points on the line.

Now, since our equation is already in the correct form, we can start with finding the opposite reciprocal of the slope. To do this, all we have to do is flip the fraction upside down and multiply by -1. This means that the opposite reciprocal of [tex]-\frac{1}{3}[/tex]  would be [tex]\frac{3}{1}[/tex] which can be written as [tex]3[/tex].

Now, since we have a list of options and only one has the correct slope, we can safely choose option A.

A store has a 20% sale on everything. An item originally cost 350 AED. What is the sale price? Show your work of how you calculated the sale price.

Answers

Answer:

Step-by-step explanation:

A store has a 20% sale on everything.

So since you are saving 20%, you will only be paying 80% of the original price.

To find the sale price use the following formula:

Sale price = 80% x original price

They told us the original price = 350 AED

This means:

Sale price = 80% x 350

I think it would be easiest to change 80% into a fraction if you don't have a calculator :)

80% = [tex]\frac{80}{100} = \frac{4}{5}[/tex]

This means that the

Sale Price= [tex]\frac{4}{5}[/tex] x 350 = 280 AED

350 (original sale price)
20% (sale)
350 x 20% = 70 (saving)
350 - 70 = 280 (spending) (new sale price)

Answer is 280 AED

p^2-4p=1
step by step explanation pleaseee

Answers

Answer:

[tex]p_1=2+ \sqrt{5}\\p_2=2- \sqrt{5}[/tex]

Step-by-step explanation:

A second-degree equation is often expressed as:

[tex]ax^2+bx+c=0[/tex]

where a,b, and c are constants.

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The equation to solve is:

[tex]p^2-4p=1[/tex]

We need to express the equation as mentioned above. The right side of the equation must be zero, so we subtract 1:

[tex]p^2-4p-1=0[/tex]

Now we have the values to solve the equation:

a=1, b=-4, c=-1

Applying the formula:

[tex]\displaystyle p=\frac{-(-4)\pm \sqrt{(-4)^2-4(1)(-1)}}{2(1)}[/tex]

[tex]\displaystyle p=\frac{4\pm \sqrt{16+4}}{2}[/tex]

[tex]\displaystyle p=\frac{4\pm \sqrt{20}}{2}[/tex]

Since 20=4*5:

[tex]\displaystyle p=\frac{4\pm \sqrt{4*5}}{2}[/tex]

Taking the square root of 4:

[tex]\displaystyle p=\frac{4\pm 2\sqrt{5}}{2}[/tex]

Simplifying by 2:

[tex]p=2\pm \sqrt{5}[/tex]

Two solutions are found:

[tex]\boxed{p_1=2+ \sqrt{5}}\\\boxed{p_2=2- \sqrt{5}}[/tex]

if syn spends 15 minutes running, he burns 200 calories. how long would it take Syn to burn 150 calories?

Answers

Answer:

11.25min

Step-by-step explanation:

In this problem, we first need to find the rate at which syn burns calories per minute

so in 15mins, he burns 200 calories

    in 1 mins he will burn x

x= 200/15

x=13.33 calories per min this is the rate

So in one minute he will burn 13.33 calories

Now using the idea of rate=quantity/time

the rate=13.33

quantity=15 calories

time=?

time=quantity/rate

time=150/13.33

time=11.25min

   Alternatively

(very fast approach)

         if syn spend 15min to burn 200 cal

then he will spend x min to burn 150 cal

cross multiply

x=(150*15)/200

x=2250/200

x=11.25mins
