Use the law of cosines to find m

Answer:

neither

Step-by-step explanation:

one lines slope is 2 and the other is -2

Given:

Consider the below figure attached with this question.

To find:

The value of x.

Solution:

We know that, the sum of all exterior angles of a quadrilateral is always 360 degrees.

The below figure represents the four exterior angles of the quadrilateral. So,

[tex]65^\circ+106^\circ+78^\circ+x^\circ=360^\circ[/tex]

[tex]249^\circ+x^\circ=360^\circ[/tex]

[tex]x^\circ=360^\circ -249^\circ[/tex]

[tex]x^\circ=111^\circ[/tex]

Therefore, the measure of x is [tex]111^\circ[/tex].

Answer: 12 boys attend Millwood School.

Step-by-step explanation:

Yeah. It just makes sense. I am bad at explaining. Sorry!

The ratio shows how many times one value is contained in another value.

The ratio of boys to girls at the Milwood School is 4 to 5.

The number of girls that attended the Milwood school is 15.

The number of boys that attended the Milwood school is 12.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio of boys to girls at the Milwood School is 4 to 5.

Total number of children = 27

Let the number of boys = 4x

Let the number of girls = 5x

Now,

4x + 5x = 27

9x = 27

x = 3

Now,

The number of boys = 4x = 4 x 3 = 12

The number of girls = 5x = 5 x 3 = 15

Thus,

The number of boys that attended the Milwood school is 12.

Step-by-step explanation:

Find the last side of the triangle using the Pythagorean theorem.

[tex]c^{2} = a^{2} + b^{2} \\20^{2} = 8^{2} + b^{2}[/tex]

B=[tex]4\sqrt{21}[/tex]

This makes b = 18.3

Now you can find the angle B = arcsin (opp/hyp)

B=arcsin [tex]\frac{4\sqrt{21} }{20}[/tex]

B= 66.42

Answer:

22°

Step-by-step explanation:

Okay, to first find the missing side, you need to use a² +b² = c²

getting 21.54 for the hypotenuse. From there, you're going to divide the leg (8) that's opposite of the angle you're trying to find and divide it by the hypotenuse (21.54). Then on you're caluclator you should have a button that says "Sin-1". You're going to use that and plug in the answer you got from 8/21.54. This'll give you your answer!

Answer:

13 / 25 were boys

14 / 25 were girls

Step-by-step explanation:

Of the girls 10 said no and 4 said yes

10 + 4 = 14 so she asked a total of 14 girls

Of the boys 8 said yes and 5 said no

8 + 5 = 13 so she asked a total of 13 boys

she asked 14 girls and 13 boys

14 + 13 = 25 so she asked a total of 25 people

Out of the 25 people she asked 13 of them were boys

So 13 out of 25 people we boys

or 13 / 25

which means 14 out of 25 were girls

or 14 / 25

Given:

The quadratic equation is:

[tex]x^2+x-30=0[/tex]

To find:

The solutions of the given equation.

Solution:

We have,

[tex]x^2+x-30=0[/tex]

Splitting the middle term, we get

[tex]x^2+6x-5x-30=0[/tex]

[tex]x(x+6)-5(x+6)=0[/tex]

[tex](x+6)(x-5)=0[/tex]

Using zero product property, we get

[tex]x+6=0[/tex] and [tex]x-5=0[/tex]

[tex]x=-6[/tex] and [tex]x=5[/tex]

Therefore, the solutions of the given quadratic equation are -6 and 5.

Answer: 12m

Step-by-step explanation:

Assuming the garden is a rectangular one, the area can be calculated by the formula:

Area = Length * Width

Given the length, one can find the width by making it the subject of the formula:

300 = 25 * Width

Width = 300 / 25

= 12 m

Answer:

57.12 cm²

Step-by-step explanation:

area = (9.28 + 5) × 8/2

Answer:

Answer:

a = - 1.1

Step-by-step explanation:

Condition for a single variable function f(x) to be decreasing is f'(x) < 0.

So, in our case, .

Then, differentiating with respect to x on both sides we get,

⇒

⇒

{Dividing both sides with - 1 and hence the inequality sign changes}

⇒

⇒ 8 > - 6x³ {Multiplying both sides with x³}

⇒ 6x³ > - 8 {Interchanging the sides}

⇒

⇒ x > - 1.1

Therefore, a = - 1.1. (Answer)

Answer:

The total number of bulbs are "320 bulbs".

Step-by-step explanation:

According to the question,

The square garden's side length,

x = 8 feet

Number of tulip bulbs she plant,

= 5

Now,

As per the question, the area of square will be:

⇒ [tex]A=x^2[/tex]

       [tex]=(8)^2[/tex]

       [tex]=64[/tex]

hence,

The total number of bulbs will be:

⇒ [tex]n=A\times 5[/tex]

       [tex]=64\times 5[/tex]

       [tex]=320 \ bulbs[/tex]

Thus the above is the correct solution.
