Step-by-step explanation:

If you know tangent of theta is 5/3 and it is in the 3rd quadrant, then you know the sides will be going in the negative direction and the real values of the sides would be -5/-3. You can use pythagorean theorem to figure out that the hypotenuse would be sqrt(5^2+3^2) = sqrt(34). Then you can use soh cah toa: sin = opp/hyp, cos=adj/hyp tan = opp/adj. You know that opp = -5, adj = -3, and hyp = sqrt(34) For cosine theta, it would be -3/sqrt(34) and csc is just 1/sin so csc would be hyp/opp = sqrt(34)/-5.

The value of x is 62

Step-by-step explanation:

Given data is:

34,37,53,55,x,x+2,77,83,89and100​

As the number of values is 10 (which is even number of values) i.e. n=10

The median will be the average of two middle values.

[tex]M = \frac{1}{2}(\frac{n}{2}th\ value + \frac{n+2}{2}th\ value})\\M = \frac{1}{2}(\frac{10}{2}th\ value + \frac{10+2}{2}th\ value})\\M = \frac{1}{2}(5th\ value + 6th\ value})\\[/tex]

As it is already given that the median is 63

Putting M=63

[tex]63 = \frac{1}{2}(x+x+2)\\126 = 2x+2\\126-2 = 2x\\124 = 2x\\\frac{2x}{2} = \frac{124}{2}\\x = 62[/tex]

Hence,

The value of x is 62

Answer:

46

Step-by-step explanation:

13.3 = H

9.2 = A

AH = cos

cos⁻¹(9.2÷13.3) = 46.23°

Answer:

[tex]\boxed {\boxed {\sf \angle z \approx 46 \textdegree}}[/tex]

Step-by-step explanation:

First, recall the three trigonometric ratios.

13.3 is the hypotenuse because it is opposite the right angle. 9.2 is the adjacent because it is next to angle z. We must use cosine.

First, plug the values into the cosine ratio.

Divide.

Next, use the inverse of cosine because we are trying to solve for the angle.

Round to the nearest degree. The 2 in the tenth place tells us to leave the 6 in the ones place.

Angle z is about 46 degrees

Answer:

40 more subs

Step-by-step explanation: 3.50 x 36 = 126    266 - 126 = 140    140 / 3.50 = 40

The number of subs to sell are 40.

Number juggling tasks are the essentials of math. Addition, subtraction, multiplication, and division are the most common fundamental operations applicable to relations. We use them almost constantly throughout the day. Every day, we use mathematical operations to calculate the company's total revenue and expenses, establish monthly or annual budgets, and measure distances.

Given total fund to raise = $266

profit on each = $3.50

total no. sold = 36 subs

cost of 36 subs = 36 × 3.50

cost of 36 subs = $126

price left to achieve $266 = 266 - 126 = $140

number of subs to be sold to get $140 = 140/3.50 = 40 subs

Therefore, 40 subs more to be sold.

Answer:

B and E

Step-by-step explanation:

Got it right

Answer:

a) a is positive and b is negative

b) a = 3, b = -15.

Step-by-step explanation:

Inequalities and Equations:

We are given:

ab = -45

a > b

a) We don't know the values of a and b, but since their product is negative, there can be only two situations:

a is negative and b is positive

a is positive and b is negative

The condition a > b rules out the first situation, thus we are sure

a is positive and b is negative

b) Since a + b = -12 we can find the values of a and b. It can be done by solving a quadratic equation but we'll do it mentally.

We have to find two numbers whose sum is -12 and product is -45. It's not so hard to find the numbers are -15 and 3. Since a is positive and b is negative, the solution is

a = 3

b = -15

Answer:

$45.26

Step-by-step explanation:

30% × 61 = 18.3

= $18.30 off, 61 - 18.3 = 42.7

6% × 42.7 = 2.562

= 42.7 + 2.562

=  45.26

Answer:

112 sheeps

Step-by-step explanation:

Sheep : Horses

8 : 3

Since horses has 3 units, it means that =

3 units = 42

1 unit = 42 ÷ 3 = 14

Find the units that sheeps have.

8 units = 14 x 8 = 112

Answer:

There will be 112 sheeps on the farm.

The area of the garden is increased by 20 % . If the width remains the same, then the new length of the garden is 2.4 yards.

The area of Rectangle is length times of width.

Given that A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide

Area = Length × Width

Area=6 yards.

The area of the garden is increased by 20 % .

20/100=0.2

the area would equal 6 (l x w) and 6 increased by 20% equals 7.2.

As the width remains same

so we use 7.2/3 to find the new length

7.2/3=2.4 yards.

Hence, 2.4 yards is the new length of the garden.

Answer:

x=7

Step-by-step explanation:

add 7 to both sides

9x=5x+28

subtract 5x from both sides

4x=28

divide both sides by 4

x=7

Answer:

X=7

Step-by-step explanation:

So first you want x on one side so you so subtract 5x from both sides

Then your equation is 4x-7=21

Because you want x by itself, you add 7 to each side because of additive inverse

The equation is now 4x=28

The last step is to divide 4 from each side and that leaves us with 7

x=7
