Sin (7pie/6)= ????????????

Hey!!!

<a and <b are complementary angles.

Those angles which are exactly 90 degree are called complementary angles.

hope it helps..

Answer:

0

Step-by-step explanation:

The discriminant is

12^2 - 4*11*4 = -32

Since it is negative, there are 0 real solutions

Answer: Trevor drinks 3 3/4 pints against his coach's 4 pints

Step-by-step explanation:

8 ounces per day x 8 times = 64 ounces = 8 cups = 4 pints

Water bottle holds 1 1/4 pints x 3 = 3 3/4 pints.

Answer: A = x^2/16 + (5 - x/4)^2 > 20.5

Hope this helped.

Answer:

As you may know, the addition of all the interior angles of a triangle always adds up to 180°.

So if we know two angles of the triangle, A1, and A2, we can find the third angle as:

A1 + A2 + X = 180°

X = 180° - A1 - A2.

Se with only knowing two angles, we can find the third angle.

So aaa is a criteria equivalent to aa.

Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.

Answer:

12

Step-by-step explanation:

use Pythagorean theorem

37^2 = 35^2 + x^2

x= ±[tex]\sqrt[2]{37^2-35^2}[/tex]

x1 = 12

x2= -12 but it is illogical as length cannot be negative

answer: x = 12

Answer: x = 12

Step-by-step explanation:

a^2 + b^2 = c^2

35^2 + b^2 = 37^2

b^2 = 1369 - 1225

b = √144 = 12

Answer:

Step-by-step explanation:

1). Segment AB = [tex]\overline{AB}[/tex] (Option D)

   Segments are represented by an over-line/bar on the segment.

2). Length of segment AB = AB (Option B)

3). MN = 7 (Option C)

   Since the measure of segments MN and KL are equal from the figure attached.

4). [tex]\overline{KL}[/tex] is congruent to [tex]\overline{MN}[/tex]

   Given in the figure attached.

Answer:

1) Segment AB =d

2) Length of segment AB = b

3)MN=c

4) [tex]\widehat{KL}[/tex] is congruent to = a

Step-by-step explanation:

We are supposed to match the items

Options:

a.[tex]\widehat{MN}[/tex]

b. AB

C. 7

d. [tex]\widehat{AB}[/tex]

1) Segment AB

So, D option denotes the segment

So, 1) Segment AB =  [tex]\widehat{AB}[/tex]

2) Length of segment AB = Option b

So, Length of segment AB =AB

4) [tex]\widehat{KL}[/tex] is congruent to

So, referring the given figure we can say

[tex]\widehat{KL}[/tex] is congruent to [tex]\widehat{MN}[/tex]

So, [tex]\widehat{KL}[/tex] is congruent to option a

3)MN

Since [tex]\widehat{KL}[/tex] is congruent to [tex]\widehat{MN}[/tex](by 4)

So, KL = MN = 7

So, MN = 7

So, MN = option c

Hence

1) Segment AB =d

2) Length of segment AB = b

3)MN=c

4) [tex]\widehat{KL}[/tex] is congruent to = a

A graph has a constant rate of change when the graph is linear and portrays a straight line. The slope will remain constant which forms the straight line in the graph.

Answer:

Because it is a straight line

Step-by-step explanation:

If it changed there would be curves, points, corners, zig zags, since this is straight, that means the R.O.C commonly known as slope, is not changing

Answer:

400

Step-by-step explanation:

75%=0.75

300/0.75 = 400

Answer:

400

Step-by-step explanation:

75/100 of x = 300

75x/100 = 300

Cross multiplying

75x = 30000

Dividing the both by 75

x = 400

Answer:

890

Step-by-step explanation:

Well, first we should put 1.1 kg into grams (1 kg = 1000g)

1.1kg= 1100g

[tex]1100-470= 630[/tex] this is how much was added by the marbles

630/ # of marbles gives the mass of each marble

[tex]\frac{630}{6} = 105[/tex]

each marble has a mass of 105 g

1100- 2m(marble)=

1100-2*105

1100-210=

890

Answer:

890 grams

Step-by-step explanation:

Remember that one kilogram is equal to 1000 grams. Therefore, 1.1 kilograms is equal to 1,100 grams. (remember 0.1 means one tenth, and one tenth of 1000 is 100)

1,100 grams is the total measure of the jar with the marbles. Subtract the weight of the jar, 470 grams, to find the measure of the marbles.

1100 - 470 = 630

Now, we can divide 630 grams by the total number of marbles, 6, to find the weight of each marble.

630/6 = 105.

Therefore, each marble weighs 105 grams.  

Now, we know that two marbles were removed from the jar that weighs 1100 grams.

Multiply 105 by 2 to find the number of grams that were taken out of the jar:

105*2 = 210

Now, we subtract 210 from 1100

1100 - 210 = 890 grams

Hope this helps :)

___________________________________

Total number of students=2200

Total percent of male=52.5%

Total percent of female=100%-52.5%

=47.5%

Total number of female= 47.5% of 2200

=47.5/100*2200

=1045

So the total number of female is 1045

hope it helps

Good luck on your assignment

Answer:

[tex]1045[/tex]

Step-by-step explanation:

[tex]no. \: \: of \: \: students = 2200[/tex]

First let's find the percentage of female.

[tex]100\% - 52.5\% = 47.5\%[/tex]

So now let's find how many female students are there in the class

[tex]2200 \times47.5\% \\ 2200 \times \frac{47.5}{100} \% \\ = 1045[/tex]

Answer:

11

Step-by-step explanation:

[tex]5=\dfrac{w}{2.2}[/tex]

Multiply both sides by 2.2 to isolate w:

[tex]w=5\cdot 2.2=11[/tex]

Hope this helps!

Answer:

[tex] \boxed{\sf w = 11} [/tex]

Step-by-step explanation:

[tex]\sf Solve \ for \ w: \\ \sf \implies 5 = \frac{w}{2.2} \\ \\ \sf \implies \frac{w}{2.2} = 5 \\ \\ \sf Multiple \: both \ side \ by \ 2.2 : \\ \sf \implies \frac{w}{ \cancel{2.2}} \times \cancel{2.2 }= 5 \times 2.2 \\ \\ \sf \implies w = 5 \times 2.2 \\ \\ \sf 5 \times 2.2 = 11 : \\ \sf \implies w = 11[/tex]

Answer:

$0.82

Step-by-step explanation:

The full answer is 0.8225, although I believe that I was supposed to round it to the nearest hundredth, so I did that. What I did was I divided 3.29 by 4.

Answer:

.82 per chocolate bar

Step-by-step explanation:

Take the price and divide by the number of chocolate bars

3.29/4

.8225

Rounding to two decimal places

.82 per chocolate bar

Step-by-step explanation:

The circumference of a wheel is 0.46π, and we simply have to multiply that by 829 which is 381.34π or 1197.41.

Answer:

see below

Step-by-step explanation:

Find the circumference

C = 2 * pi *r

C = 2(.23) * pi

C = .46pi

Since the wheel rotated 829 times, multiply the circumference by 829

829 * .46 pi

381.34 pi

If  pi = 3.14

1197.4076 meters

If using the pi button

1198.01494 meters

Answer:

c = 160 - 3(45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3*(45)

c = 160 - 135

c = 25

Answer:

The correct option is C.

Step-by-step explanation:

To have this credit card there is two fees, one that is fixed payed upfront and other that is payed after the second month. The fixed fee costs $62, and doesn't escalate with time, while the other one is $30 and starts to be charged after the second month. Therefore, the total cost of the card is the fixed fee plus the monthly fee multiplied by the number of months the user had the card subtracted by two, or as shown below:

[tex]C(g) = 62 + 30*(g-2)[/tex]

The correct option is C.

b*h/3 is the formula to find the volume (or area whichever it is) of a pyramid  so it will be 16 times 30 divided by 3 which would get u to 480/3 which would then get u to 160 cm
