Answer:

I and IV

Step-by-step explanation:

cosine is positive/greater than 0 in quadrants I and IV. Its just a rule of the unit circle.

Can remember by All Star Trig Class

meaning all the trig funtions are positive in quadrant I

sin is positive in II

tan is positive in III

and cos is positive in IV

Step-by-step explanation:

You need to give us the choices. However, I will try and give you the answer.

The highest common factor is 8

8(x^2 - 3)     This is the answer I think the question expects.

8(x - √3 )(x + √3)  this is also possible

Answer: A is right. B is acute, C is obtuse, and D is right.

Step-by-step explanation:

The right triangles have the square in the corner.

Triangle C is a little bit bigger than a right triangle.

Triangle B is acute because its smaller than a right triangle.

Answer:

5/1 = 5

Step-by-step explanation:

because 5/1 equals 5.

Answer:

Option 2  [tex]\frac{4\sqrt{6} }{3}[/tex]

Step-by-step explanation:

[tex]\frac{4\sqrt{2} }{\sqrt{3} } = \frac{4\sqrt{2} \sqrt{3} }{\sqrt{3}\sqrt{3} } = \frac{4\sqrt{6} }{3}[/tex]

Answer:

x = 36°

Step-by-step explanation:

x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }

5x = 200° - 20°

5x = 180°

x = 180° / 5

x = 36°

Hope it will help :)

Answer:

its 63 lol

Answer:

X = -3

Step-by-step explanation:

Answer:

It is the second one.

Step-by-step explanation:

a and e are equal because they are mirrored. d and b are equal because they are on the same  line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.

Answer:

3=111

Step-by-step explanation:

Answer:

1. Move the variables to one side: 3(-4+4) = -3n

2. Distribute. You will end up with 0 = -3n

3. Divide both sides by -3. n = 0

Step-by-step explanation:

Answer:

n=0

Step-by-step explanation:

3(-4+4)+5n=2n

first distribute

-12+12+5n=2n

combine like terms

5n=2n

subtract 2n on both sides

3n=0

divide by 3 on both sides

n=0/3

which is also equal to

n=0

Answer:

204

Step-by-step explanation:

The area of the top triangle = 5*12/2 =                        30

The area of the bottom triangle =                                30

The hypotenuse of the top triangle is

5^2 + 12^2 = hypotenuse^2

25 + 144 = hypotenuse^2

169 = hypotenuse squared.

hypotenuse = sqrt(169)

hypotenuse = 13

Now the back face = 13 * 8 =                                       104

The area of the left side rectangular  face = 5*8 =     40

The total area = 30 + 30 + 104 + 40 =                        204

Answer:

[tex]2.5h = 3g[/tex]

Step-by-step explanation:

Given

[tex]Sugar = 2\frac{1}{2}\ cups[/tex]

[tex]Bars = 3\ pans[/tex]

Required

Determine the equation for h pans and g cups

We have that:

[tex]Sugar = g[/tex]

[tex]Bars = h[/tex]

To do this, we make use of the following equivalent ratios.

[tex]Bars : Sugar = Bars : Sugar[/tex]

So, we have:

[tex]3 : 2\frac{1}{2} = h : g[/tex]

Express fraction as decimal

[tex]3 : 2.5 = h : g[/tex]

Express as fraction

[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]

Cross multiply

[tex]2.5h = 3g[/tex]

No options were given. So, I will stop here

Answer:

160yds²

Step-by-step explanation:

A = ((a + b) ÷ 2) × h

A = ((19 + 13) ÷ 2) × 10 = 160

good luck, i hope this helps :)

Answer:

-6

Step-by-step explanation:

-30÷5=-6

this is the ans

the total no of population=1650

13:17 first add the two numbers 13+17=30

then 13/30×y =715 , i make 13 at the numerator because it's males ratio

after that 30/13×13/30y =715 ×30/13

y =715×30/13

y =1650

after u find the total no it's simple to find the no of females

17/30×1650=935

Answer:

C=1.80g

Step-by-step explanation:

Answer:

The median of a list of numbers is the center number when you order the numbers from least to greatest.

Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.

Step-by-step explanation:

List in order from least to greatest

(3.25, 3.25, 3.66, 3.83)  4.44  ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher.  So the median number is 4.44

For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74)  = 36.85  Then divide by 9 = 4.09

Answer:

15/28 loads of laundry needs to be washed.

Step-by-step explanation:

2/7 + 1/4

=  

2 × 4 + 1 × 7

7 × 4 + 4 × 7

=  

8/28 + 7/28

=  

8 + 7/ 28

=  

15/28
