Carlos bought a new cell phone. The graph represents the
relationship between the number of minutes he uses
and the total
cost. What is the equation of the line?
A) y= 5x + 0.1
B) y=0.1x + 5
C) y=0.5x + 5
D) y = 5x + 5
Answers
Answer:
B : y = 0.1x + 5
Step-by-step explanation:
using the y = mx + b equation
b is the intercept on the y axis ( x = 0)
m is the slope of the line.
From the graph we can see that the intercept is (0,5), therefore b = 5;
To calculate slope (m) pick two pints on the line e.g (100, 15) and (0, 5)
m = (y2 - y1)/(x2 -x1) = (15 - 5)/(100 - 0) = 10/100 = 0.1
m = 0.1
therefore in y = mx + b
y = 0.1x + 5

A group spends $277.50 to rent a total of 15 tubes. How many of each type of tube does the group rent?
Answers
The amount spent on each tube is $18.5
The total amount spent to rent 15 tubes by the group is $277.50.
Since they did not specify in the question the types of tubes they rented, we cannot determine each types of tubes that the group rented but we can determine the amount spent on each tube provided that they are all the same types.
∴
if 15 tubes = $277.50
1 tube = $x
By cross multiplying:
[tex]\mathbf {\$(x) = \dfrac{ \$277.50 \times 1 \ tube }{15 \ tube}}[/tex]
[tex]\mathbf {(x) = \$18.5}[/tex]
Therefore, we can conclude that the amount spent on each tube is $18.5

knife is 3 times cost of spoon
9 spoons and 12 knifes is £82.80
what is 1 knife
Answers
Answer:
The cost of spoon is £1.84 and therefore the cost of one knife is £5.52.
Given :
A knife is 3 times the cost of the spoon. 9 spoons and 12 knives costs £82.80.Solution :
This question is solve by creating a linear equation and linear equations are nothing but yet another subset of "equations". Linear calculations that requires more than one variable can be done with the help of linear equations. The standard form of a linear equation in one variable is ax + b = 0.Now let x be the cost of spoon. Than the cost knife is 3x. It is given that 9 spoons and 12 knives costs £82.80.
[tex]9x + 12 x (3x) = 82.809x + 36x = 82.8045x = 82.80x = 1.84[/tex]
Therefore the cost of 1 knife = 5.52
Step-by-step explanation: [tex]1.84 x 3 = 5.52[/tex]

Last week, Byron bought 5 containers of yogourt and spent $12.88 on other groceries.
This week casandra bought 3 containers of the same yogourt and spent $11.50 on other groceries. How much more money did byron spend than casandra
Answers
Answer:
Byron spent 0.62 cent more than Casandra.
Step-by-step explanation:
It says how much more money did Byron spend than Casandra?
So you have to take how much Byron had and subtract it by how much Casandra had.
$12.88 - $11.50 = $0.62
And that's how you get your total on how much more did Byron spend than Casandra.

==========================================================
Explanation:
First we'll need the length of segment BD, which I'll call x for now. The similar triangles allow us to set up the proportion below to solve for x
AD/BD = BD/DC
13/x = x/4
13*4 = x^2
52 = x^2
x^2 = 52
x = sqrt(52)
Segment BD is exactly sqrt(52) units long.
------------
Now focus your attention on triangle BDC. We'll use the pythagorean theorem to find BC
(BD)^2 + (DC)^2 = (BC)^2
( sqrt(52) )^2 + ( 4 )^2 = ( m )^2
52 + 16 = m^2
68 = m^2
m^2 = 68
m = sqrt(68)
m = 8.2462 approximately
m = 8.2

Step-by-step explanation:

1/5 of 85=17
17x4=68
4/5 of 85=68
(1). The ratio of red tiles to blue tiles is [tex]\frac{1}{4}[/tex]
(2). The number of blue tiles are 68.
Fraction:It is given that,
A path is made by red and blue tiles and [tex]\frac{1}{5}[/tex] part of tiles are red.
So that,
Blue tiles[tex]=1-\frac{1}{5} =\frac{4}{5}[/tex] parts.
The ratio of red tiles to blue tiles in its simplest form,
[tex]\frac{Red}{Blue}=\frac{1}{5}*\frac{5}{4} \\\\\frac{Red}{Blue}=\frac{1}{4}[/tex]
Since, total number of tiles are 85.
Number of blue tiles[tex]=\frac{4}{5} *85=68[/tex]

Answer:

Step-by-step explanation:
The triangle has all sides equal therefore all the angles are equal.
For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.
Therefore y=90-60
=30
x=180-(30+90)

What is inequalities?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Millie has a bank account balance of $1,497. Each week, her balance changes by - $83. She wants to keep the balance above $750.
Establishing an inequality,
750 > 1497 - 83x
