Answer:

The perimeter of the equilateral triangle is 90 units.

Step-by-step explanation:

Let the side of the triangle be = s

So, perimeter of equilateral triangle = [tex]s+s+s=3s[/tex]

One side measures 9+3x and the measure of another side is 5x-5.

Both are equal, so we get the sides as:

[tex]9+3x=5x-5[/tex]

[tex]3x-5x=-5-9[/tex]

[tex]-2x=-14[/tex]

x = 7

We get the sides as :

First side [tex]9+3(7)[/tex]

= 30

OR

Second side [tex]5(7)-5[/tex]

= 30

And the third side will also be 30 as it is equilateral triangle.

Hence, the perimeter is = [tex]30+30+30=90[/tex] units

Therefore, the perimeter of the equilateral triangle is 90 units.

Answer:

6 x 10/3= 6000

Step-by-step explanation:

take ur first digit,6,and either multiply it by 10/3 =1000 or place to its right as many zeroes as the exponent of ten (3)

The student is working with scientific notation, specifically converting 6 x [tex]10^{-3}[/tex] into standard notation, which results in the number 0.006.

The student in question appears to be dealing with scientific notation and its application in representing large or small numbers in a condensed form. In scientific notation, numbers are represented as a product of a base number and 10 raised to a certain power. For instance, 6 x 10/3 is a way to represent the number 0.006, indicating the decimal point has been moved three places to the left.

To convert 6x10/3 into standard notation, you need to recognize that the exponent -3 on the 10 denotes how many places to move the decimal. Since it is negative, we move the decimal to the left. Therefore, we rewrite 6 as 0.006, which is the standard notation.

For this case we must factor the following expression:

[tex]x ^ 2-3x-4[/tex]

We must find two numbers that, when multiplied, result in -4, and when added, result in -3.

These numbers are: -4 and +1

[tex]-4 + 1 = -3\\-4 * (+ 1) = - 4[/tex]

So:

[tex]x ^ 2-3x-4 = (x-4) (x + 1)[/tex]

Answer:

[tex](x-4) (x + 1)[/tex]

Option A

Answer:

(x+1) and (x-4)

Step-by-step explanation:

Since, factors of an expression is the values which after multiplying together give the same expression.

Given quadratic equation,

[tex]x^2 - 3x - 4[/tex]

By the middle term splitting,

[tex]x^2 - (4 - 1)x - 4[/tex]

By distributive property,

[tex]x^2 - 4x + x - 4[/tex]

[tex]x(x-4)+1(x-4)[/tex]

[tex](x+1)(x-4)[/tex]

Since,

[tex]x^2 - 3x - 4=(x+1)(x-4)[/tex]

i.e. the factors of [tex]x^2 - 3x - 4[/tex] are (x+1) and (x-4).

To create the formula, identify the relationship between cost and number of journeys from the graph. Assume a simple linear function y = mx + b. Calculate the slope (rate of cost per journey) and y-intercept (initial or fixed cost) to find final equation: c = mn + b.

In order to work out a formula for c (cost) in terms of n (number of journeys), we need to understand the relationship between these two variables. From the graph, we can make the assumption that this relationship is linear, suggesting a simple algebraic formula of the form y = mx + b, where y is the dependent variable (cost), x is the independent variable (number of journeys), m is the slope of the line and b is the y-intercept.

To establish our formula, we need to calculate the slope and y-intercept. The slope is found by taking the change in y over the change in x (the 'rise' over 'run'). The y-intercept is the cost (c) when the number of journeys (n) is zero.

Once these quantities are determined from the graph, your formula could look like: c = mn + b, where m is the slope (change in cost per journey) and b is the cost for zero journeys (fixed cost).

Answer:

w = 14 - (L/2)

Final answer:

The width, W, of the rectangular football field is expressed as W = (1/2)L + 14, which signifies that the width is half of the field's length plus an additional 14 meters.

Explanation:

If L represents the length of the football field, the expression for the width, W, is W =  rac{1}{2}L + 14. This is because the width is given as 14 meters more than half of the field's length. So, to write this relationship as an expression, we start by taking half of the length, denoted as  [tex]rac{1}{2}L[/tex], and then add 14 meters to this value to account for the additional width.

Answer:

a. Fraction of earnings that Mariano put into each piggy bank  is 1/12

b. Mariano earns $28.8

Step-by-step explanation:

Mariano divides his earning in a saving account and 3 piggy banks.  

First ,  we have to know the fraction that we divide in the 3 piggy banks.

Piggy banks =Total earning-Saving account

Saving account 3/4,  

Total earning is 1

to rest both term we have to get the same denominator , so we can say that the total earning is 4/4

Piggy banks =4/4-3/4=( 4-3)/4=1/4

Piggy banks =1/4

Each piggy bank will be 1/3 of that 1/4

1/3 x 1/4=

For fraction multiplication, multiply the numerators and then multiply the denominators to get

1×1/3×4=1/12

This fraction cannot be reduced.

b. Mariano adds $2.40

1/12 is 2.40

total earning  is ?

We use cross-multiplication

a/b=c/d  replacing   (1/12)/2.40 = 1/ ?

So,  the total earning (?) is 1 x 2.40/ (1/12)

= 2.40 x 12=$28.8

Mariano puts 3/4 of his earnings in his savings account and divides the rest equally into 3 piggy banks. The fraction of his earnings that he puts into each piggy bank is (1/12)x dollars. Mariano earns 0 dollars per week delivering papers.

To find the fraction of Mariano's earnings that he puts into each piggy bank, we need to calculate 3/4 of his earnings first. Let's assume he earns x dollars per week. Therefore, he puts 3/4 of x dollars into his savings account, which is (3/4)x dollars. The remaining (1/4)x dollars is divided equally into 3 piggy banks. So, each piggy bank gets (1/12)x dollars.

To find out how much Mariano earns per week delivering papers, we need to solve the equation (3/4)x + (1/12)x = x. Simplifying the equation, we get 9x/12 + x/12 = x. This is equivalent to (10/12)x = x. Multiplying both sides by 12, we get 10x = 12x. Subtracting 10x from both sides, we get 2x = 0. Therefore, x = 0.

2.75+3x=4.25+2.50x

3x - 2.50x = 4.25 - 2.75

0.50x = 1.50

x = 1.50 ÷ 0.50

x = 3

Total 1920 cubes can fit in the given prism.

Dimensions of prism are: [tex]2\dfrac{2}{5} = \dfrac{12}{5}[/tex] ,  [tex]3\dfrac{1}{5} = \dfrac{16}{5}[/tex],  and 2 inches respectively.

Size of a side of given cube = 1/5 inch

Number of cubes that can fit in given prism.

This problem is all about spaces. Only that number of cube will fit, which the prism will allow to. The given prism has got some space in it(The volume), and the cubes have some size (their volume).

Since prism is a cuboid(which is mistakenly written as rectangular in the question), thus we have:

Volume of prism = multiplication of lengths of its sides = [tex]\dfrac{12}{5} \times \dfrac{16}{5} \times 2 = \dfrac{384}{25}[/tex] cubic inches

Volume of the cube = cube of its one side's length = [tex](\dfrac{1}{5})^3 = \dfrac{1}{125}[/tex] cubic inches

We will divide the total space with space amount each cube take so as to find number of cubes allowed by prism to be fitted in it.

Thus:

[tex]\text{Number of cubes} = \dfrac{\dfrac{384}{25}}{\dfrac{1}{125}} = 1920 \: \rm cubes[/tex]

Step-by-step explanation:

Let's say Rani's present age is x. Her age is twice the age of her daughter.

So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.

1/2(20)=daughter's age

so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.

A. The sum is a rational expression.

The sum of the given fractions a/b + c/d, where a, b, c, and d are polynomials, can be calculated by finding a common denominator, which is typically the product of polynomials b and d, and combining the adjusted numerators.

The question deals with the operation of addition of fractions where the denominators are polynomials. Given the expression a/b + c/d, where a, b, c, and d are polynomials, and b and d are non-zero polynomials, we want to find their sum. It is important to note that adding or subtracting fractions requires a common denominator.

To combine a/b with c/d, we must first find a common denominator, which will be the product of b and d if they have no common factors. After that, we adjust the numerators accordingly and perform the addition. The resulting fraction will have a numerator that is the polynomial sum of ad and bc, and a denominator that is the polynomial product bd.
