Can someone help me please

Answer:

Step-by-step explanation:

The Pythagorean Theorem holds for both positions.

The first configuration is an 6-8-10 right triangle.

The second configuration using the Pythagorean Theorem:

10^2 = (8-2x)^2 + (6 + x)^2

100 = 64 - 32x + 4x^2 + 36 + 12x + x^2

100 = 100 - 20x + 5x^2

5x^2 - 20x = 0  

5x(x - 4) = 0

x = 4 feet (we throw out the x = 0 solution as extraneous)

Step-by-step explanation:

Given

Base Dimension

[tex]Length = 4\frac{1}{4}yd[/tex]

[tex]Width = 1\frac{2}{3}yd[/tex]

Required

The base area of all containers

First, calculate the base area of 1 container.

This is calculated as:

[tex]Area = Length * Width[/tex]

[tex]Area = 4\frac{1}{4}yd * 1\frac{2}{3}yd[/tex]

Express as improper fraction

[tex]Area = \frac{17}{4}yd * \frac{5}{3}yd[/tex]

So, we have:

[tex]Area = \frac{17*5}{4*3}yd^2[/tex]

[tex]Area = \frac{85}{12}yd^2[/tex]

The number of containers is not given. So, I will use 'n' as the number of containers.

So, we have:

[tex]Total = n * Area[/tex]

[tex]Total= n * \frac{85}{12}yd^2[/tex]

--------------------------------------------------------------------------------------------

Assume n is 3 (i.e. 3 containers)

The total area is:

[tex]Total= 3 * \frac{85}{12}yd^2[/tex]

[tex]Total= \frac{85}{4}yd^2[/tex]

[tex]Total= 21\frac{1}{4}yd^2[/tex]

Answer:

V = 400in.

Step-by-step explanation:

We are given the measurements of what can be assumed to be a rectangular prism, and we need to find the volume.

When finding volume of a rectangular prism, we need to multiply length by width by height.

So we know all of these,

L = 10in

W = 5in

H = 8in

V = LWH

Substitute :

V = (10)(5)(8)

Mutiply :

V = (50)(8)

Multiply :

V = 400in.

Answer:

the formula to find volume is length times width times height.

Step-by-step explanation:

10 times 5 = 50 then multiply 50 by 8 which equals 400. brainliest :0

Answer:

[tex]\frac{12}{5}[/tex]

Step-by-step explanation:

4/5x=3/10(x+4)  / · 10

8x=3(x+4)

8x=3x+12

8x-3x=12

5x=12  /:5

x=12/5

The expression is equivalent to the 1/4 (12 -3x) is 3 - 3/4x.

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the Expression

1/4 (12 - 3x)

Now, using Distributive Property we get

a x (b+ c) = a x b + a x c

Then, 1/4 (12 - 3x)

= 1/4(12) - 1/4 (3x)

= 3 - 3/4x

Thus, the required expression is 3 - 3/4x.

Step-by-step explanation:

(g is the variable for garnish)

Answer:

3cm

Step-by-step explanation:

The length of a rectangle Is 9cm

The perimeter Is 24

Let the width be x

Therefore the width can be calculated as follows

Perimeter= 2(length+width)

24= 2(9+x)

24= 18+2x

24-18= 2x

6= 2x

x= 6/2

x= 3cm

Hence tbe width is 3cm

Answer:

-25 = -(4v+7)+10

-25 = -4v-7+10

-25 = -4v+3

4v = 3+25

4v = 28

v = 28 ÷ 4

v = 7

Answer:

Therefore the value of v in the equation is 7

Answer:

a

Step-by-step explanation:

a is the correct statement because there is a relative minimum at 3pi/4 and y values are negative on the interval [pi/2,pi]

The function is negative on the interval (π/2, π) option (A) is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a graph of a sin function shown in the picture.

As we know the sin function can be defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is the amplitude of the function.

The sin function is:

f(x) = sin(2x)

From the graph, the region between (π/2, π) the function values is negative because the function exists in the IV quadrant.

Thus, the function is negative on the interval (π/2, π) option (A) is correct.

Given:

The line passing through (-2,5) and (2,p) has a gradient of [tex]-\dfrac{1}{2}[/tex].

To find:

The value of p.

Solution:

If a line passes through two points, then the slope of the line is:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The line passing through (-2,5) and (2,p). So, the slope of the line is:

[tex]m=\dfrac{p-5}{2-(-2)}[/tex]

[tex]m=\dfrac{p-5}{2+2}[/tex]

[tex]m=\dfrac{p-5}{4}[/tex]

It is given that the gradient or slope of the line is [tex]-\dfrac{1}{2}[/tex].

[tex]\dfrac{p-5}{4}=-\dfrac{1}{2}[/tex]

On cross multiplication, we get

[tex]2(p-5)=-4(1)[/tex]

[tex]2p-10=-4[/tex]

[tex]2p=-4+10[/tex]

[tex]2p=6[/tex]

Divide both sides by 2.

[tex]p=3[/tex]

Therefore, the value of p is 3.

Hello! Your answer would be B)B

Step-by-step explanation:

Hope I helped! Brainiest plz!♥ Have a nice morning! Hope you make a 100%! -Amelia

Focus on the values in red outside the table (on the left and right sides). As the output increases by 4, the input increases by 1. This leads to the slope being rise/run = 4/1 = 4. The slope is the number just to the left of the x variable. So that's how they ended up with the equation y = 4x.

You can think of it as y = 4x+0, and note how it's in the form y = mx+b

m = 4 = slope

b = 0 = y intercept

The y intercept is the value of y when x = 0.

--------

Now because x = 0 and y = 0 pair up together, we can find the slope a different way: Pick any row other than the first row. Divide the y value over its paired x value. So let's say we pick on row two and we'd get a slope of y/x = 4/1 = 4.

Or we could pick on row three and get y/x = 8/2 = 4.

Picking on the fourth row gets us the slope to be y/x = 12/3 = 4. We end up with the same slope value each time. Again, this trick only works if (x,y) = (0,0) is on the line. Otherwise, you'll need to use the first method or use the slope formula.

For equations like this, we consider them a direct proportion. As x increases, so does y. As x increases by 1, y increases by 4. This is the same throughout the table.

----------

A real world example of this could be that x represents the number of sodas you buy, and if each soda is $4, then y = 4x represents the total cost of buying x number of sodas.

For instance, if you bought x = 10 sodas, then y = 4*x = 4*10 = 40 dollars is what you spend overall.
