4/8 plus 2/4 find the common denomnator

Answer:

  d.  94.25 in²

Step-by-step explanation:

The area of this composite figure is the sum of the areas of a semicircle and a triangle. Each of those areas can be found using the appropriate formula:

  semicircle: A = (π/2)r²

  triangle: A = 1/2bh

__

The semicircle has a radius equal to half its diameter. The radius is (10 in)/2 = 5 in. Its area is ...

  A = (3.14/2)(5 in)² = 39.25 in²

The area of the triangle with base 11 in and height 10 in is ...

  A = 1/2bh

  A = 1/2(11 in)(10 in) = 55 in²

The area of the figure is the sum of the areas of the semicircle and triangle, so is ...

  figure area = (39.25 in²) +(55 in²)

  figure area = 94.25 in²

Answer:

Niki will pay $425 after the discounts.

Step-by-step explanation:

Cherry originally costs 150$, and you can subtract the discount of 50$ from that to get 100$ total for cherries.

Banana originally costs 200$, and you can subtract the discount of 25$ from the original cost to get 175$ total for bananas.

Watermelon originally costs 125$, and after subtracting the discount of 25$, you can determine the total cost for watermelons, which is 100$.

Mangoes originally costs 75$, subtract the discount of 25$, and you get the total for mangoes at 50$.

Add the costs after discounts (100$ for cherry, 175$ for banana, 100$ for watermelon, 50$ for mangoes), and you get 425$, which is the total cost for the fruit after discounts.

Answer: 25/8

Step-by-step explanation:

[tex]\rule{300}{1}\\\dashrightarrow\large\blue\textsf{\textbf{\underline{Given question:-}}}[/tex]

Change 3+1/8 to an improper fraction.

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]

First, multiply the whole part (3) times the denominator (8):-

[tex]\bold{3\times8=24}[/tex]

Now add the numerator:-

[tex]\bold{25}[/tex]

That's the numerator of the improper fraction, and the denominator stays the same.

[tex]\bigstar[/tex] Therefore, the fraction is

[tex]\bold{\dfrac{25}{24}}[/tex]

[tex]\rule{300}{1}[/tex]

Answer:

[tex]\huge\boxed{\sf x = 8.2}[/tex]

Step-by-step explanation:

Since it is a right-angled triangle, we will apply Pythagoras Theorem.

Given are:

Base = 16

Perpendicular = x

Hypotenuse = 18

Pythagoras Theorem:

[tex]\sf (Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]

(18)² = (16)² + (x)²

324 = 256 + x²

Subtract 256 to both sides

324 - 256 = x²

68 = x²

Take sqrt on both sides

8.2 = x

x = 8.2

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

We have,

We know that,

[tex] \large\boxed{\sf (Hypotenuse)^2=(Perpendicular)^2+(Base)^2}[/tex]

[tex]\longmapsto \sf \: (18)^2=(16)^2+x^2[/tex]

[tex]\longmapsto \sf \: (18)^2-(16)^2=x^2[/tex]

[tex]\longmapsto \sf \: x^2=324-256[/tex]

[tex]\longmapsto \sf \: x^2=68[/tex]

[tex]\longmapsto \sf \: x = \sqrt{68}[/tex]

[tex]\longmapsto \sf \: x ≈8.25 [/tex]

The area of the triangle based on the information given will be 4 units square

It should be noted that the area of a triangle is calculated by using the formula:

= 1/2 × base × height

Therefore, the area of the triangle will be:

= 1/2 × base × height

= 1/2 × 2 × 4

= 4 units²

In conclusion, the area of the triangle given will be 4 units square.

If it has a line under it it is equal too as well as greater or less.

The close dot means equal too and the open mean not equal to

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

The plumber spend 3 hours to fixing the sink if the plumber fixed a leaky sink and charged $55 for parts and $45 per hour for labour.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the plumber spend x hours to fixing the sink.

Then we can frame a linear equation in one variable:

55 + 45x = 190

45x = 135

x = 3 hours

Thus, the plumber spend 3 hours to fixing the sink if the plumber fixed a leaky sink and charged $55 for parts and $45 per hour for labour.

Answer:

y = (3/4)x-9/2

Step-by-step explanation:

We've got two points, (-2, -6) and (2, -3). That's more than enough info to construct a line. The slope of the line is the ratio between the change in y (Δy) and the change in x (Δx). Here, Δy = -3 - (-6) = -3 +6 = 3, and Δx = 2 - (-2) = 2 + 2 = 4, so the slope is Δy/Δx = 3/4. From here, we can use the point-slope form of a line to get a general equation. With the slope m = 3/4 and choosing the point (2, -3), we have

[tex]y-y_1=m(x-x_1)\\y-(-3)=(3/4)(x-2)\\y+3=(3/4)x-3/2\\y=(3/4)x-3/2-3\\y=(3/4)x-3/2-6/2\\y=(3/4)x-9/2[/tex]

Based on the calculations, for any number n > 1, [tex]|(\frac{1}{2} + \frac{3i}{4} )^n|[/tex] is less than one but not greater than or equal to one.

First of all, we would simplify the equation by using the lowest common multiple (LCM) of the fractions as follows:

[tex]|(\frac{2\;+\;3i}{4} )^n|[/tex]

By applying exponent rule, we have:

[tex](a.b)^n=a^n \times b^n\\\\|(\frac{(2\;+\;3i)^n}{4^n} )|\\\\|(\frac{(2\;+\;3i)^n}{(2^2)^n} )|[/tex]

By applying exponent power rule, we have:

[tex]|(\frac{(2\;+\;3i)^n}{2^{2n}} )|[/tex]

Assuming n = 2, we have:

[tex]|(\frac{(2\;+\;3i)^2}{2^{2\times 2}} )|\\\\|(\frac{(2\;+\;3i)^2}{2^{4}} )|\\\\|(\frac{-5\;+\;12i}{16} )|[/tex]

Therefore, for any number n > 1, [tex]|(\frac{1}{2} + \frac{3i}{4} )^n|[/tex] is less than one but not greater than or equal to one.

Now,

To find the number of different combo meals possible, we can use the fundamental counting principle. This states that if there are m ways to do one thing and n ways to do another thing, then there are m x n ways to do both things.

2 ways to choose a drink

4 ways to choose a main dish
