It is to be noted that the height of the bread is 5 centimeters. The hint given is in the information about the surface area. See the explanation below.
What is the surface area?In this case, the surface area of bread is the total sum of the area of the base and perimeter. The surface area of the bread is given below.
That is:
A = 2 x b + p x H,
Where b is the area of the base, p is the perimeter of the base and h is the height.
Recall that it is stated that 50% of the surface area of the bread is the crust.
The implication is that the surface area of both sides of the base is equivalent to the surface area of its perimeter.
That is:
2 x b = p x h
We can compute the perimeter of the bread as:
P = 4 x length
p = 4 x 10
p = 40cm
The area of the base is:
b = 10 x 10
b = 100cm²
Substituting the values in the above formula,
2 x 100 = 40 x h
200 = 40h
h = 200/40
h= 5cm.
Hence the height of the bread is 5cm.

A mobile company has the following plans on their website. STANDARD PLAN: $40 for 5GB (potential starting point) and $15/GB thereafter (this is a rate of change, so it could be a slope)
UNLIMITED PLAN: $80 Always, with no additional charges.
The equation for the unlimited plan is y=80.
Write an equation (y=mx+c) for the standard plan.
IT IS NOT Y=15X+40
Answer:
y = 15x - 35
Step-by-step explanation:
STANDARD PLAN information:
$40 for 5GB.$15 per GB thereafter.Define the variables:
Let x be the number of GB.Let y be the cost in dollars.If it costs $40 for the first 5GB then y = 40 when 0 ≤ x ≤ 5.
It costs $15 per GB after the first 5GB. Therefore:
When x = 6, y = 40 + 15 = 55.When x = 7, y = 40 + 15(2) = 70.When x = 8, y = 40 + 15(3) = 85.Therefore:
⇒ y = 40 + 15(x - 5)
⇒ y = 40 + 15x - 75
⇒ y = 15x - 35

What is the value of (−15)3 when evaluated? 3,375 45 −225 −3,375
The value of the exponential form (-15)³ is -3375.
The f(x)= exp (x) or eˣ are used to represent the exponential function in mathematics (where the argument x is written as an exponent).
The term typically refers to the positive-valued function of a real variable, unless otherwise specified, though it can also be extended to the complex numbers or modified to refer to other mathematical objects like matrices or Lie algebras. The exponential function originated from the concept of exponentiation, or repeated multiplication; but, more recent definitions—of which there are many that are equivalent—allow it to be rigorously extended to all real arguments, including irrational values.We know that any exponential form such as (-15)³ can be written as
-15×-15×-15 = -3375
Therefore the solution of the exponential form is -3375 .

Elijah buys 112worth of stereo equipment from stereo store there is a 2.5 processing fee for using a credit card what is the totalcost of the stereo equipment
By using percentage, we conclude that the total cost of the stereo equipment is $114.8.
The worth of stereo equipment is $112 and there is a 2.5% processing fee for using a credit card.
Whenever we purchase anything with a credit card we have to pay a processing fee that a Bank charges.
To find the total cost of the stereo equipment, we have to add the worth of the stereo equipment and processing fee for using a credit card.
And to find the processing fee for using a credit card, we have to calculate 2.5% of the worth of the stereo equipment.
So, 2.5/100 x 112 = 2.8
Therefore, the required processing fee for using a credit card is $2.8.
The total cost of the stereo equipment = $112 + $2.8 = $114.8

how does the speed at which you drive affect your fuel economy? to find out, researchers drove a compact car for 200 miles at speeds ranging from 35 to 75 miles per hour. from their data, they created the model fuel efficiency
Using linear function concepts, the interpretation of the slope of the model is:
The slope indicates that the Fuel Efficiency decreases by an amount of 0.15 mpg for every 1 mile per hour increase of speed.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
m is the slope of the function, which is the rate of change of the function.b is the y-intercept of the function, which is the initial value of the function.For this problem, the model is given as follows:
Fuel Efficiency = 32 - 0.15Speed.
The slope is of m = -0.15, meaning that for each mph that the average velocity increases, the fuel efficiency decays by 0.15 mpg.
What is the missing information?The model is missing, and is given as follows:
Fuel Efficiency = 32 - 0.15Speed.

The population of a city decreases by 1.7% per year. If this year's population is 366,000, what will next year's population be, to the nearest individual?
The population of the city next year, after decreasing, will be 359,778
Here, we are given that the population of a city decreases by 1.7 percent per year.
This, means that the city's population will decrease by 1.7% in 1 year, (1.7 × 1.7)% in 2 years and so on.
The population of the city this year is given to be 366,000.
Thus, next year, the population will decrease by-
1.7% of 366,000
= 1.7/100 × 366,000
= 17/10 × 3,660
= 17 × 366
= 6,222
Thus, the city's total population next year will be-
366,000 - 6,222
= 3,59,778
Hence, the city's population to the nearest individual comes out to be 359,778.

PQRSTUVW is a cuboid.
Find the angle between the line PV and the plane PTWS.
Give your answer correct to 1 decimal place.
The angle between the line PV and the plane PTWS is 29.4°
In this question we have been given a cuboid PQRSTUVW
We need to find the angle between the line PV and the plane PTWS.
First we find the length of the line PW which is diagonal of rectangular surface PTWS.
In right triangle PWS by Pythagoras theorem,
PW² = PS² + SW²
PW² = 19² + 16²
PW² = 361 + 256
PW² = 617
PW = 24.84 cm
now, consider a right triangle PWV.
Consider tangent of angle VPW
tan(∠VPW) = VW / PW
tan(∠VPW) = 14 / 24.84
∠VPW = tan^{-1}(0.5636)
∠VPW = 29.4°
Therefore, the angle between the line PV and the plane PTWS is 29.4°

Answer:
Explanation below:

So basically x is the diameter - so is the radius times by 2
The radius is the length from the center of the circle to the edge which in this case is 7.9 + 8.9 = 16.8
So from this we have worked out the radius which is 16.8
But x is the diameter so we have to times 16.8 by 2 which gives 33.6

What is a line of best fit?A line of best fit can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.
In this scenario, the game would be plotted on the x-axis of the scatter plot while the attendance would be plotted on the y-axis of the scatter plot.
By critically observing the scatter plot (see attachment) which models the data in the given table, we can reasonably and logically deduce that a linear equation for the line of best fit is given by:

Jeweler needs 144 inches of silver chain to make the necklaces and 108 inches of silver chain to make the bracelets.
What is defined as multiplication?Multiplication, along with addition, subtraction, and division, is one of the four fundamental arithmetic operations. Multiplication in mathematics refers to the repeated addition of gatherings of equal size.The signs cross (x), asterisk (*), and dot (.) represent multiplication.The commutative property states so when we multiply 2 numbers, the order has no effect on the product.The Associative Property states because if we multiply three or more numbers one after the other, this same order does not matter.For the given question;
The total length of silver chain jeweler had = 36 inches.
Length of silver chain required to make necklaces = 4 times.
So, multiply 36 with 4 to get the result;
36 x 4 = 144.
Thus, the silver chain required to prepare the necklaces is 144 inches.
For the making of bracelets = 3 times the length of silver chain.

The equation y=0.52x+186 gives the cost y of renting a car if the care is driven x miles. Based on this equation, for every mile the car is driven the cost of increases by how much?
For every mile the car is driven, the cost increases by 0.52 units.
Consider a line that passes through the origin at a distance 'a' from the Y-axis and has a slope of m. In this situation, the distance an is the definition of the line's y-intercept. At this moment, the line will cross the y-axis (0, a). The equation for the line will then be y = mx + a. The same goes for a line that crosses the X-axis at a position b from the origin and has a slope of m. (b,0). The distance b is the line's x-intercept. The equation for the line will be y = m* (x-b)
Given, the equation that relates cost of renting and miles driven is
y = 0.52 x + 186
Therefore, for a car travelling one mile, cost is y₁ = 0.52*1 + 186 = 186.52
For a car travelling two miles, cost is y₂ = (0.52*2) + 186 = 187.04
Thus, for every next mile the cost increases by = y₂ - y₁ = 187.04 - 186.52 = 0.52 units
