40 ft converted into yards

Answer:

1

Step-by-step explanation:

So first we do (x^5)^2 which we know is just x^10 because of exponents of powers I believe it's called, basically you just multiply the two powers.

Then you do the bottom half which is x^3 * x^7 and that equals x^10 because of the product of exponent rule,

Then we do x^10/x^10 which = 1 because the same number over the same number is always 1.

Let me know if you have any questions

Answer:

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Step-by-step explanation:

We need to solve the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex]

We know that exponent rule: [tex](a^m)^n=a^{m*n}[/tex]

Applying this rule in numerator

[tex]\frac{(x^5)^2}{(x^7)(x^3)}\\=\frac{(x^{5*2})}{(x^7)(x^3)}\\=\frac{(x^{10})}{(x^7)(x^3)}[/tex]

We know the exponent rule: [tex](a^m).(a^n)=a^{m+n}[/tex]

[tex]=\frac{(x^{10})}{x^{7+3}}\\=\frac{(x^{10})}{x^{10}}[/tex]

Now, using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

[tex]=x^{10-10}\\=x^0[/tex]

We know that [tex]a^0=1[/tex]

So, [tex]x^0=1[/tex]

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Answer:

2 unique triangles

Step-by-step explanation:

We can only form two triangles

Since two of the sides are equal, we can form two isosceles triangles

The first one will have 10, 10 , the last side, then 40, 70 , 70 as the internal angles

Just note that the angles must add up to be 180 and that there are two equal angles as we are dealing with an isosceles triangle

The second form is 10, 10 , 40 , 40 and 100

Here, we have the 40 on the sides of the base of the isosceles triangle with the measure 100 being the last angle

The number of unique triangles that can be formed with he given parameters are; 2

We are told that;

Two side lengths of the triangle = 10 cm

One angle = 40°

Now, the two equal angles could be 40° each.

Thus;

Third angle of the triangle = 180 - 2(40) = 100°

(180 - 40)/2 = 140/2

>> 70°

Thus, we can make 2 unique isosceles triangles.

Answer: She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.

Step-by-step explanation:

GIven: Total documents needed to be done = 12

If she finished writing all documents by Friday, then the number of documents written on Friday = 12-(work done by Wednesday) - (work done on Thursday)

[tex]= 12 -(3\dfrac15)-(5\dfrac34)\\\\=12-\dfrac{16}{5}-\dfrac{23}{4}\\\\=\dfrac{12\times20-16\times4-23\times5}{20}\\\\=\dfrac{240-64-115}{20}\\\\=\dfrac{61}{20}\\\\=3\dfrac{1}{20}[/tex]

Answer:

Longest side = 110 cm

Step-by-step explanation:

The extended ratio of the sides of a triangle is 7:8:10

Let sides are 7x, 8x and 10x.

The perimeter of the triangle is 275 cm.

Perimeter of a triangle = sum of all sides

7x+8x+10x = 275

25x = 275

x = 11

Longest sides of the triangle = 10x

= 10 (11)

= 110 cm

So, the longest side of the triangle is 110 cm.

Answer:

x = 4

Step-by-step explanation:

x + 4(x+5) = 40 (Given)

x + 4x + 20 = 40 (Distribute the 4 into the x and 5)

5x + 20 = 40 (Add like terms)

5x = 20 (Subtract 20 on both sides)

x = 4 (Divide 5 on both sides)

Answer:

C. 14cm

Step-by-step explanation:

The square of the longest line, in an obtuse triangle, is greater than the sum of the squares of the other two sides. So it is appropriate for equivalent legs to have a length

L^2 + l^2=2l^2

14^2+14^2=20^

196+196=400

392=400 400

A) For the city of Everettt, y-intercept  represent the number of chrome books they started with.

y - intercept = 550

Everett started the 2016 year with 550 chrome books

B)  y = 50x + 300

Explanation: They stared with 300 books at 2016. This will be the y-intercept

Rate of change = 50 books per year which will the slope

m = 50 and b = 300

y = mx + b

y = 50x + 300

The measure of angle NMQ is 73 degrees

The given parameter is:

[tex]\angle MNP = 107[/tex]

From the given figure, angles MNP and NMQ are adjacent angles.

Given that the adjacent angles of a trapezoid add up to 180 degrees.

We have the following equation

[tex]\angle MNP + \angle NMQ = 180[/tex]

Make NMQ the subject

[tex]\angle NMQ = 180 -\angle MNP[/tex]

Substitute 107 for MNP

[tex]\angle NMQ = 180 -107[/tex]

[tex]\angle NMQ = 73[/tex]

Hence, the measure of angle NMQ is 73 degrees
