I need help on all of number 2!!!!

Answer:

The answer is B

Step-by-step explanation:

All other fractions when simplified are equal to 2/5

The answer i got is -1.55, im not sure though

The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression, x - y

x = - 5 1/4 = (-5 x 4 + 1)/4 = -19/4 = -4.75

y = -6.8

Substitute x and y into the above expression,

-4.75 - (-6.8) = 2.05

Hence "The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05".

x = 40

Answer:

you plug in the x-values into the equation to get the y-values:

y=2(1)+5

y= 2+5

y=7 or (1,7)

y=2(4)+5

y=8+5

y=13 or (4,13)

y=2(5)+5

y=10+5

y=15 or (5,15)

y=2(10)+5

y=20+5

y= 25 or (10,25)

[tex]4900 {mm}^{2} [/tex]

Step-by-step explanation:

[tex]1 cm = 10mm \\ 1cm \times 1cm = 10mm \times 10mm \\ 1 {cm}^{2} = 100 {mm}^{2} \\ 49 {cm}^{2} = 49 \times 100 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 4900 {mm}^{2} [/tex]

If the tree grew by five centimeters each year, then the tree will grow 50 cm in 10 years.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given information in the question,

Age when John hammered a nail in the tree = 6 years

John returned to the age of sixteen, then the number of years in between that,

16 - 6 = 10 years.

Rate of increase in height of tree per year = 5 cm

Then, after 10 years, the height of the nail of the tree will be,

10 × 5 = 50 cm.

Answer:

Ounces of green paint needed = 13.8

Step-by-step explanation:

Blue paint : green paint = 25 : 115

how many ounces of green paint should she mix with 3 ounces of blue paint?

Let

Ounces of green paint needed = x

Blue paint : green paint = 3 : x

Equate both ratios

25 : 115 = 3 : x

25/115 = 3/x

25 * x = 115 * 3

25x = 345

x = 345/25

x = 13.8 ounces

Ounces of green paint needed = 13.8

Answer:

The length of the shorter part of the wire is 24 centimeters.

Step-by-step explanation:

Let [tex]L[/tex] the total length of the piece of wire, where [tex]L-x[/tex] and [tex]x[/tex] are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are [tex]\frac{L-x}{4}[/tex] and [tex]\frac{x}{4}[/tex]. From statement we find that the sum of the areas of the two squares ([tex]A[/tex]), measured in square centimeters, is represented by the following expression:

[tex]A = \left(\frac{L-x}{4} \right)^{2}+\left(\frac{x}{4} \right)^{2}[/tex] (1)

And we expand this polynomial below:

[tex]A = \frac{L^{2}-2\cdot L\cdot x +x^{2}}{16} + \frac{x^{2}}{16}[/tex]

[tex]A = \frac{L^{2}-2\cdot L\cdot x +2\cdot x^{2}}{16}[/tex]

[tex]2\cdot x^{2}-2\cdot L\cdot x +L^{2}-16\cdot A = 0[/tex] (2)

If we know that [tex]L = 76\,cm[/tex] and [tex]A = 205\,cm^{2 }[/tex], then the length of the shorter part of the wire is:

[tex]2\cdot x^{2}-152\cdot x +2496 = 0[/tex]

By the Quadratic Formula, we determine the roots associated with the polynomial:

[tex]x_{1} = 52\,cm[/tex], [tex]x_{2} = 24\,cm[/tex]

The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

Answer: 16π

Step-by-step explanation:

First, solve for total area:

A = πr^2

A = π(8^2) = 64π

Then, find 1/4 of the area of the whole (since this is only a quarter circle)

A/4 = (64π)/4 = 16π

3 is not in the range.

A function's range is the whole set of potential values that it can have. When we insert an x value into the function, the range is the collection of values that results. Range refers to the y values.

Given a figure in which the function is not differentiable since the graph is broken at  (-2, 3) and (2, 4). Since at Y = 3 there is no point in the graph. therefore Y = 3 is not in the range of the function.

Answer:

21/8

Step-by-step explanation:

okay so what we have to do is called flip n' multiply, so we leave the first fraction the way it is and the second one, we flip. so instead of 3/9, it would be 9/3. now we just do 7/8 times 9/3 to get 63/24 which I believe will be simplified to 21/8

Answer:

Seven eighths divided by three ninths is equal to twenty-one eights.

Step-by-step explanation:

The easiest way to divide one fraction by another is to simply multiply the first one by the second one.  It's that easy:

[tex]\frac{7}{8} \div \frac{3}{9}[/tex]

is exactly the same as:

[tex]\frac{7}{8} \times \frac{9}{3}[/tex]

Which we can then solve by multiplying the numerators by each other and multiplying the denominators by each other

[tex]\frac{7}{8} \times \frac{9}{3}\\\\ = \frac{7 \times 9}{8 \times 3} \\\\ = \frac{63}{24} \\\\ = \frac{21}{8}[/tex]

Another way you can solve it is by noting that in the second number, both the numerator and denominator are divisible by 3, which gives a way to simplify before doing the division:

[tex]\frac{7}{8}\div \frac{3}{9}\\\\= \frac{7}{8}\div \frac{1}{3}\\\\= \frac{7}{8}\times \frac{3}{1}\\\\= \frac{7}{8}\times 3\\\\= \frac{21}{8}[/tex]
