The length of the bar is 10.5 foot and the width of the bar is 5.7 foot .

In the question ,

it is given that

the base area of the large chocolate bar is 59.85 square foot .

let the length of the chocolate bar be "l"

and the breadth of the chocolate bar be "b"

given that the length is 0.9 foot shorter than twice its width , means

l = 2w - 0.9

we have the area of rectangle = length [tex]\times[/tex] width

Substituting the values of length , width and area we get

59.85 = (2w - 0.9 ) * w

59.85 = 2w² - 0.9w

2w² -0.9w -59.85 = 0

On solving the quadratic equation ,

we get w = -5.25 and w = 5.7

width cannot be in negative , so, the width is 5.7 foot .

and l = 2(5.7) -0.9 = 11.4 - 0.9 = 10.5

Therefore , the length of the bar is 10.5 foot and the width of the bar is 5.7 foot .

-72 is less than -56

In a rectangle of area 50 the value of x is 5

Area of a rectangle is given by multiplication of the length and the width

Area was given as 50

length = x + 10

width = x

Area = L * w

50 = (x + 10) * x

50 = x^2 + 10x

rearranging the equation

x^2 + 10x - 50

factorizing gives

x - 5x + 10x - 50

x(x- 5) + 10(x - 5)

(x - 5)(x + 10)

therefore

x = 5 or x = -10

taking the positive value

x = 5

The new account balance of Clare is calculated as $127.38 by using the given data.

A mathematical operation is a mathematical action. A mathematical operation includes addition, subtraction, multiplication, division, and computing the root.

In math, a word problem is a question expressed in one or more sentences that asks learners to apply their arithmetic skills to a'real-life' scenario. This implies that in order to understand the word problem, students must be conversant with the terminology linked with the mathematical symbols to which they are used.

Given:

Clare has a savings account balance of $102.38. She uses the ATM to deposit three cheques she received for her birthday. Each check was made out for $15.00. She then takes out $20 in cash.

Amount in her savings account = 102.38

Amount after depositing 3 checks = 102.38 + 3(15)

                                                         = 147.38

Amount after withdrawing $20 in cash = 147.38 - 20

                                                                = 127.38

Therefore, the new account balance of Clare is calculated as $127.38 by using the given data.

The slope of the tangent line at the point x = a of the function f(x) is f'(a).

We are given the function:

Computing the first derivative:

The slope of the tangent line at (1, 1), that is, where x = 1 is:

The tangent line and the normal line are perpendicular to each other. If their respective slopes are m1 and m2, then:

We have calculated m1 = -1, calculate m2:

Now we know the slope of the normal line. We need to find its equation. Use the point-slope formula:

y - k = m(x - h)

Where m is the known slope and (h, k) is a point of the line. We are given the point (1, 1), thus:

y - 1 = 1(x - 1) = x - 1

Adding 1:

The inequality model will be 40*x + 15*y ≤ $1200.

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.

The given information, cost of a Jersy = $40

Cost of Hat = $15

The softball team has a total of $1,200 to spend.

Let x equal the number of jersey’s the team orders and y equal the number of hats the team orders.

So the total money will be spend within the budget will be

40*x + 15*y ≤ $1200

In this scenario, we are considering if-then statements. Looking at the given statement,

p = angle A is an obtuse angle

q = the measure of angle A = 75 degrees

A statement of if q, then p would be

q - p

where - is an arrow pointing to the right

Looking at the picture, the symbol before p represents negation. It tells us that

if q, then not p. By translation, the correct answer would be

Answer as a fraction: x= 223  24/25

Let's solve this equation step-by-step!

5(x−225)=−5.2

Step 1: Simplify both sides of the equation.

5(x−225)=−5.2

An explicit formula for the sequence -2,3,8,13,18  is aₙ = 7 - 5n.

The express method for a mathematics collection is an = a + (n - 1)d, and any time period of the collection can be computed, without knowing the opposite terms of the collection. In preferred, the explicit method is the nth time period of mathematics, geometric, or harmonic sequence.

Calculation:-

a₁ = 2

a₂ = 2 - 5 = -3

a₃  = -3 - 5 = -8

a₄ = -8 -5 = -13

a₅ = -13 -5

    = -18

The formula for the nth term of explicit sequence is aₙ = a₁ +(n - 1)d

where a₁ = 2 and d = 5

So,

aₙ =2 + (n - 1)(-5) using distributive property

aₙ = 2 + n (-5)+(-1)(-5)

aₙ = 2 - 5n + 5

aₙ = 7 - 5n
