Brianna bought snacks for her team's practice. She bought a bag of
oranges for $2.63 and a 8-pack of juice bottles. The total cost before
tax was $16.07. Write and solve an equation which can be used to
determine x, how much each bottle of juice costs?
Answers
Answer:
$1.68
Step-by-step explanation:
The total cost is $16.07 and there was 2 things bought- the oranges and the juice bottles. to make it easier to find the cost of the juice bottles, we'll subtract the cost of the oranges (2.63) from the total (16.07), which gives us 13.44. this number represents the total cost of only the bottles. To find out the cost if each individual bottle, you need to divide the total (13.44) by the number of bottles (8). This gives us 1.68, so the cost of each bottel is $1.68

Answers
First, you can see that female business is 44-30=14. Then, you can see that female premium is 62+14+x=108, or x=32. So, because 32 females bought premium and there are 60 total premium, the number of male premium is 60-32=28 male premium tickets.

Answers
To find the line that goes through (5,1), we can use a blank equation y=mx+b. We know that m=-1, so we can use the given point to find b:
y=mx+b
Y=-x+b
1=-5+b

Step-by-step explanation:
We know that a pentagon is a polygon with 5 sides and 5 angles.
Given the polygon with 5 angles.
A pentagon is a polygon with 5 sides and 5 angles.
The angles of the given pentagon are:
∠P = (4x + 2)°
∠Q = 132°
∠R = (4x - 10)°
∠S = (5x - 11)°
∠T = 128°
We know that the sum of the measures of the interior angles of a pentagon is 540 degrees.
Therefore,
∠P + ∠Q + ∠R + ∠S + ∠T = 540°
(4x + 2)° + 132° + (4x - 10)° + (5x - 11)° + 128° = 540°
group similar elements
4x + 4x + 5x + 2 + 132 - 10 - 11 + 128 = 540
simplify
13x + 241 = 540
subtract 241 from both sides
13x + 241 - 241 = 540 - 241
13x = 299
divide both sides by 13
13x/13 = 299/13
x = 23
Thus, the value of x = 23
Therefore, the measure of angle ∠S is:
m∠S = (5x - 11)°
= (5(23) - 11)°
= (115 - 11)°
= 104°
Thus,
m∠S = 104°
Solve for x

What is the y and x intercept and can i get a step by step explanation
Answers
Answer:
the slope is -3/2, and the y-intercept is 5/2.
Step-by-step explanation:
3x + 2y = 5
putting it into a y = mx+b form,
2y = -3x + 5
y = -3/2x + 5/2
the slope is -3/2, and the y-intercept is 5/2.
Answer:
y-intercept= 2.5
x- intercept= 1.666666666..... or 5/3
Step-by-step explanation:
1. Move variable to other side.
3x+2y= 5
-3x -3x
2y= -3x+5
2. Divide each side by 2.
-3/ 2 = -1.5
5/2 = 2.5
y= 1.5x+2.5
y= mx+b
b= y-intercept
b=2.5
3. Replace y with 0 to solve for x intercept.
3x+ 2 x 0 = 5
3x= 5
5/3 = x

A running track has two straight sides with length 140 m and two semicircle ends with radius 70 m. It takes Kat 40 seconds to jog 160 m. How long would it take her to jog around the track 51 times? Give your answer in hours and minutes, to the nearest minute.
Answers
It would take her 4590 seconds to jog round the track 51 times
Speed is the ratio of the total distance travelled to total time taken. It is given by:
Speed = distance / time
Kat uses 40 seconds to jog 160 m, hence:
Speed = 160 m / 40 s = 4 m/s
The track length = 140 m + 2 * (π * 70) = 360 m
Time taken to jog round the track (t) is:
4 m/s = 360 m / t
t = 90 s
To jog round the track 51 times, time taken = 51 * 90 s = 4590 seconds
It would take her 4590 seconds to jog round the track 51 times

Answers
Answer: .10d+.25q<_ 4
Step-by-step explanation:
d= dimes and q = quarters
dimes are worth .10 and quarters are worth .25
The inequality for the given situation is
0.1d + 0.251 ≤ 4
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
10 dimes = 1 dollar
1 dime = 0.1 dollar
4 quarters = 1 dollar
1 quarter = 0.25 dollar
Now,
The maximum amount is $4.
So,
0.1d + 0.251 ≤ 4
Thus,
The inequality is 0.1d + 0.251 ≤ 4.

3. The diameter of a cylindrical column is 60cm and
its height is 4.2m
The cost of making it is £67.50 per cubic metre.
What is the cost of making it?
Answers
Answer:
£80.33
Step-by-step explanation:
The formula for the Volume of a cylinder = πr²h
The diameter of a cylindrical column is 60cm and its height is 4.2m
Converting the diameter to meter
100 cm = 1 m
60 cm = x
Cross Multiply
100 × x = 60 × 1
x = 60/100
x = 0.6m
The diameter of the cylinder = 0.6m
Radius = Diameter/2
Radius = 0.6m/2
Radius = 0.3m
Volume of a cylinder = πr²h
= π × 0.3² × 4.2
= 1.18752 m²
Approximately = 1.19 m²
The cost of making it is £67.50 per cubic metre. What is the cost of making it?
The volume of the cylindrical column = 1.19 m²
Hence:
1m² = £67.50
1.19m² = x
Cross Multiply
x × 1m² = 1.19 m² × £67.50
x = 1.19 m² × £67.50/1 m²
x = £ 80.325
Approximately = £80.33
Therefore, the cost of making the cylindrical column = £80.33
