a book store was selling 7 books for $39.55. online you could buy 3 books for $24.96. which place has a lower unit price

Answers

Answer:

the book store selling 7 books for $39.55 (the book store)

Step-by-step explanation:

we have to calculate what each book costs. to find out what each book costs, we have to use division...

so for the book store:

39.55 / 7 = 5.65       -       this means that each book costs $5.65 by itself

for the online store:

24.96 / 3 = 8.32       -       this means that each book costs $8.32 by itself

now we have to compare the prices... $5.65 costs less than $8.32, so the book store would have a lower unit price.

Round this number to the nearest one.

Number graph ranging from negative twenty to twenty in increments of two on the x and y axes. A dotted line with a positive slope is drawn in the fourth quadrant of the graph. The area above the line is shaded gray.

Answers

A solid line passes through (-1, 0) and (0, 3). The area to the left of the line is shaded gray.

How to get the graph of the inequality?

Here we have the inequality:

3y - 9x ≥ 9

First, we should isolate y on one side of the inequality.

3y  ≥ 9x + 9

y  ≥ 3x + 3

Then, the graph will be a solid line of the form:

y =  3x + 3

Where the line is solid because the points on the line are solutions, and we need to shade all the region above the line.

Also, notice that for the line:

y = 3x + 3

if x = -1 we have:

y = 3*(-1) + 3 = 0

if x = 0 we have:

y = 3*0 + 3 = 3

Then the line passes through (0, 3) and (-1, 0). So the correct option is the second one.

Answer:

159.25cm²

Step-by-step explanation:

A=lw

A=12×10cm

The rectangle’s area is 120cm² 

First, substitute the given information into the equation for the area of a circle.

A=πr²

A=(3.14)(5²)

A=3.14×25

A=78.5

Next, because the figure is only half of a circle, divide this in two.

78.5/2= 39.25cm²

Asc=39.25cm²

Add the two areas together.

A=Ar+Asc

120cm²+39.25cm²

Evaluate the expression when x = 4 and y = 5.

Answers

Answer:

60

Step-by-step explanation:

The evaluated expression of 3x² + 4y⁰(x - 1) when x = 4 and y = 5 is  60.

What is Substitution?

Substitution simply means to put in place another. Therefore, let's substitute the value of x and y in the mathematical expression.

3x² + 4y⁰(x - 1)

Therefore,

y⁰ = 1

3x² + 4y⁰(x - 1)

3x² + 4y⁰(x - 1)

3x² + 4(x - 1)

3x² + 4x - 4

Therefore, when x = 4 and y = 5

3(4)² + 4(4) - 4

48 + 16 - 4 = 60

How far is the top of the ladder from the ground, Enter your answer as a decimal to the nearest tenth.

Can someone help I’ve been stuck on this question for almost a hour (please help).

Answers

Answer:

12.7

Step-by-step explanation:

Its a pythagerous question question

so if the ladder is 8 feet from the wall the base is 8

and the ladder is 15 foot and is the hypotemuse

so 15^2-8^2=161^2

The root of 161 = 12.69 rounded to 2 dp

so 12.7

The distance far the top of the ladder from the ground is 12.7 feet

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

We are given that;

Length= 15foot

Base= 8feet

Now,

In this case, the ladder is the hypotenuse, and the base and the height are the legs. So, we can write:

15^2 = 8^2 + h^2

where h is the height of the ladder from the ground. Solving for h, we get:

h^2 = 15^2 - 8^2

h^2 = 225 - 64

h^2 = 161

h = sqrt(161)

h = 12.688

Therefore, by  Pythagoras theorem the answer will be 12.7 feet.

Answers

The total number of outcomes is 16 if the two spinners are used in a game. Each spinner has four equal sections: red, green, white, and blue.

What are permutation and combination?

A permutation can be defined as the number of ways a set can be arranged, order matters, but in combination, the order does not matter.

Total number of outcomes on the first spinners = 4 (red, green, white, blue)

Total number of outcomes on the second spinners = 4 (red, green, white, blue)

Total number of outcomes = 4×4 = 16

Total outcomes:

RR    RG    RW   RB

Which explicit function defines this arithmetic sequence?

-351, -343, -335, -327, -319

A.
f(n) = 8n − 351
B.
f(n) = -8n − 351
C.
f(n) = 8n − 359
D.
f(n) = -8n + 359

Answers

Answer:

  C.  f(n) = 8n − 359

Step-by-step explanation:

The given arithmetic sequence has first term -351, and common difference (-343 -(-351)) = 8. The common difference will be the multiplier of n in the explicit function.

__

You can identify the appropriate explicit function by finding the one that correctly describes the sequence. Evaluating each for n=1 is sufficient. (You will note that choices B and D have the wrong sign on the multiplier of n.)

A f(1) = 8 -351 = -343

B f(1) = -8 -351 = -359

C f(1) = 8 -359 = -351 . . . . correctly gives the first term

D f(1) = -8 +359 = 351

The sequence is defined by the explicit function ...

  f(n) = 8n -359

Find the amount of money Ethan has after giving
to his mother, the ratio becomes 3:4:6.
$50 to his mother.
(Step by step explain pls)

Answers

Answer:

$450

Step-by-step explanation:

Let E be the amount of money Ethan starts with, J be the amount Jun Wei starts with, and R be the amount Raj starts with. Let M be the total amount of money to start with.

To start:

[tex]E:J:R = 5:6:9[/tex]

This means Ethan has 5/20 of M, the money to start with. This reduces to 1/4 of M.

Afterwards:

[tex](E-50):J:R = 3:4:6[/tex]

This means Ethan has 3/13 of the remaining money (which is M-50!) after giving up 50. So

E = (M/4), or 4E = M

and

[tex](E - 50) = 3/13 * (M - 50)[/tex]

We know 4E = M, so we can substitute that in:

[tex](E - 50) = 3/13 * (4E - 50)E - 50 = (12/13)E - 150/13E - 650/13 = (12/13)E - 150/13(1/13)E = 500/13E = 500[/tex]

That's how much money Ethan had to start with. But we're asked how much he has AFTER giving $50 away, so that's $450.

Answer: x = 3, y = -1

Step-by-Step Explanation:

=> 4x + 5y = 7 (Eq. 1)
=> y = 3x - 10 (Eq. 2)

Substitute value of ‘y’ from Eq. 2 in 1 :-

4x + 5y = 7
4x + 5(3x - 10) = 7
4x + 15x - 50 = 7
19x - 50 = 7
19x = 7 + 50
19x = 57
=> x = 57/19 = 3

Therefore, x = 3

Substitute value of ‘x’ in Eq. 2 :-

y = 3x - 10
y = 3(3) - 10
y = 9 - 10
=> y = -1

Therefore, y = -1
