The ratio of the number of sheep to the number of horses on a farm is 8:3 if there are 42 horses on the farm, how many sheep are there on the farm?
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.

Step-by-step explanation:
▪You can solve using proportion!
[tex] \frac{8 \: sheep}{3 \: horses } = \frac{x}{42 \: horses} \\ \\ \frac{3x}{3} = \frac{336}{3} \\ \\ x = 112[/tex]

the following data have been aranged in ascending order. if their median is 63 find value of x. 34,37,53,55,x,x+2,77,83,89and100
Answer:
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

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.

You are selling subs to raise funds for a school field trip. You make a profit of $3.50 for each sub you sell. You have already sold 36 subs. How many more subs do you need to sell to raise at least $266?
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.
What is Arithmetic operations?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.

Solve for x:
9x – 7 = 5x + 21
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

what is the domain of the function g(x)=3^x-1
a and b are integers such that ab = -45
a > b
a) What do you know about the values a and b?
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

Shannon is making a pile of square origami paper, whose sides are measured as 4n + 3. Form an expression that is equivalent to the perimeter of one sheet of the origami paper. Be sure to show the steps taken to produce your expression.
Answer:
16n+12
Step-by-step explanation:
If all four sides measure 4n+3, then the perimeter is 4 times the length of each side. 4(4n+3) = 16n + 12 = perimeter

Step-by-step explanation:gfdgdfg
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.
What is Area of Rectangle?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.

Trigonometry, find the missing angle!
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.
sin(θ)= opposite/hypotenuse cos(θ)= adjacent/hypotenuse tan(θ)= opposite/adjacent13.3 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.
hypotenuse= 13.3 adjacent= 9.2First, plug the values into the cosine ratio.
cos(z)=9.2/13.3Divide.
cos(z)=0.691729323Next, use the inverse of cosine because we are trying to solve for the angle.
z= cos⁻¹(0.691729323) z= 46.23284386Round to the nearest degree. The 2 in the tenth place tells us to leave the 6 in the ones place.
z≈46Angle z is about 46 degrees
