Answer:

Step-by-step explanation:

the donkey eats 3/5 of hay bale a week

3/5 x 2 = 6

the donkey eats 6 hay bales in 10 weeks

The amount of bales the donkey eats in 10 weeks is 6 bales.

Given,

A donkey eats three-fifths of a hay bale a week.

We need to find out how many bales he eats in 10 weeks.

Example:

2 miles in 1 hour

2 miles = 1 hour

To find miles in 4 hours we multiply both sides by 4.

4 x 2 miles = 4 x 1 hour

8 miles = 4 hours

We have,

Donkey eats:

3/5 bales = 1 week ____(1)

In 10 weeks:

Multiply 10 on both sides of (1)

10 x 3/5 bales = 10 x 1 week

6 bales = 10 weeks

Thus the amount of bales the donkey eats in 10 weeks is 6 bales.

Answer:

x=-14

Y=40

Perimeter=(4×14+3)×4=236

Step-by-step explanation:

as long as it's a square then

[tex]3x + 17 = 4x + 3 \\ 4 x - 3x = 3 - 17 \\ x = - 14 \\ \\ any \: angle \: in \: the \: square \: equal \: 90degrees \\ then \\ 5x + 4y = 90 \: \: when \: x = -14 \\ 4y = 5 \times 14 + 90 \\ 4y = 16 \\ y = 40[/tex]

[tex]perimeter =( 4 \times 14 + 3)\times 4 = 236[/tex]

X = 14

Y = 5

The perimeter of the square = 236

It's square so

3x + 17 = 4x + 3

3x + 17 - 4x - 3 = 0

-x + 14 = 0

X = 14

And

5x + 4y = 90, x = 14

5(14) + 4y = 90

70 + 4y = 90

4y = 20

Y = 5

The perimeter of a square is the total length of all the sides of the square, length = 59

The perimeter of the square = 4 × 59 = 236

Answer:

x = 21.4

Step-by-step explanation:

Reference angle (θ) = 25°

Opposite = 10

Adjacent = x

Apply trigonometric function, TOA:

Tan θ = Opp/Adj

Tan 25 = 10/x

x*Tan 25 = 10

x = 10/Tan 25

x = 21.4450692 ≈ 21.4 (nearest tenth)

Answer:

19 pounds of apple was shared and 3 pounds of apple were left to be shared for the students

A

Answer:

D. 22

Step-by-step explanation:

We're looking for the sum of 19 pounds and 3 pounds. The teacher gave out 19 pounds of apples. After giving them out, they had 3 pounds left of the total. To find the total, we need to add those amounts:

19 + 3 = 22

We can check our answer by doing this:

22 - 19 = 3

As you can see, if you had 22 pounds of apples and gave out 19 pounds, you are left with 3 pounds. This is the amount left, as mentioned in the problem. The answer is D.

Step-by-step explanation:

The probability is P = 0.894

a) Determine the probability that a student will begin college during the summer semester and attend an in-state college.

The probability is given by the quotient between the number of students that start on summer semester and attend to an in-State college, and the total number of students that start on the summer semester.

The number of students starting on the summer semester is:

178 + 21 = 199

Of these 199 students, 178 will attend to an in-state college, so our probability is:

P = 178/199  = 0.894

Answer:

Let

x=sin-¹u

Sinx=u

let y=tan-¹v

tany=v

Substituting

Sin[x + y]

Applying the sine expansion

Sinxcosy + CosxSiny

Recall x =Sin-¹u

y=tan-¹v

Sin(Sin-¹u)Cos(tan-¹v) +Cos(sin-¹u)Sin(tan-¹v)

Now at this point

Here's what you do

For the first expression

Sin(Sin-¹u)

Let's simplify this

Let P = Sin-¹u

Taking sine of both sides

SinP=u

Draw a Right angled angle for this

Since Sine from SOHCAHTOA is OPP/HYP

Where P is the angle and u is the opposite and 1 is the hypotenuse since u is the same as u/1

substituting Sin-¹u = P

You have

Sin(Sin-¹u) = SinP

and from the triangle you drew

SinP = u

Taking the second express

Cos(tan-¹v)

Let Q=Tan-¹v

taking tan of both sides

tanQ=v

Draw a right angled triangle for this too

Since Tan from SOHCAHTOA is OPP/ADJ

Find the Hypotenuse cos you'll need it

Now Let's do the substitution again

We first said tan-¹v = Q

When we substitute it in Cos(tan-¹v)

We have CosQ

Cos Q from the second right angle triangle you drew is 1/√1+v²

Because CAH is adj/Hyp

So

the first part of the original Express

Which is

Sin(Sin-¹u)Cos(tan-¹v) is now simplified to

u(1/√1+v²).

Let's Move to the second part of the Original Expression

Cos(Sin-¹u)Sin(tan-¹v)

From our first solution

We said Sin-¹u= P

So replacing it here

we have Cos(sin-¹u) = CosP

let's leave the second one for now which is sin(tan-1v) We'll deal with this after the first

so Cos(Sin-¹u) = CosP

we can still use our first Right angle triangle for this because the angle was P.

so Cos P from that triangle will be

CosP= √1-u²

Now onto the next

Sin(tan-¹v)

From the Second solution of the first we did

we said let Tan-¹v =Q

Substituting this

we have

Sin(tan-¹v) = SinQ

using the second Right angle triangle because its angle is Q

We have

SinQ= v/√1+v²

Answer for second phase Which is

Cos(sin-¹u)Sin(tan-¹v) = √1-u²(v/√1+v²)

We're done

compiling our answers

The answer to

Sin(Sin-¹u - tan-¹v) = u(1/√1+v²) + [(√1-u²)(v/√1+v²)]

You can still choose to factor out 1/√1+v² since it appears on both sides

Answer:

48 cm^2

Step-by-step explanation:

The area of one of the triangular ends is A = (1/2)(4 cm)(3 cm) = 6 cm^2.

Multiply this "base area" by 8 cm, the length of the prism.  We get:

volume of triangular prism = (6 cm^2)(8 cm) = 48 cm^2

Answer:

for the first questions: 36%

Step-by-step explanation:

To answer the first question: What percent of people chose Mexican food?

Number of people who choose mexican food: 27

Total number of people who took the survey: 24 + 27 + 9 + 15 = 75

So, 27 out of 75 people choose mexican food, or in other words 27/75. If you divide 27/75, you get the decimal 0.36. This decimal is the same thing as 36%.

The steps for the other three questions are the same.
