Answer:

51.3°

Step-by-step explanation:

Step 1: Use tan to find angle y

o = 10

a = 8

[tex]tan()=\frac{o}{a} \\tan(y)=\frac{10}{8} \\y = tan^{-1} (\frac{10}{8})\\y = 51.3[/tex]

Therefore angle "y" is 51.3° rounded to the nearest tenth

Answer:

Step-by-step explanation:

They are similar triangles.  Since 6 is 1.5 times the four, x has to be 1.5 times the 6.

6*1.5=9

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the line parallel to the equation above we must first find the slope of the above equation

y = - 74x - 2

Comparing with the above formula

Slope = - 74

Since the lines are parallel their slope are also the same

Slope of parallel line = - 74

Equation of the line using point (4 , -2) and slope - 74 is

y + 2 = 74( x - 4)

y + 2 = 74x - 296

y = 74x - 296 - 2

We have the final answer as

To the nearest whole number

59 ft/second

Answer:

[tex]\Large \boxed{\mathrm{59 \ feet \ per \ second}}[/tex]

Step-by-step explanation:

1 mile = 5280 feet

40 miles = 5280 × 40 = 211200 feet

1 hour = 3600 seconds

[tex]\displaystyle \sf \frac{211200 \ ft}{3600 \ s}[/tex]= 58.666666666... ft/s

Answer:

Step-by-step explanation:

The rate of change of number of tree y on x branches of a tree is expressed as shown;

m = Δy/Δx where;

m is the rate of change

Δy is the change in number of leaves  between 3 and 4

Δx is change in number of branches  between 3 and 4

m = Δy/Δx = y₂-y₁/x₂-x₁

From table between 3 and 4, y₂ = 100, y₁ = 75, x₂ = 4, x₁ = 3

m = 100-75/4-3

m = 25/1

m = 25

Hence the rate of change between 3 and 4 branches is 25

Let x be the no.of square feet for landscaping

Company A

Monthly consulting fee = $250

Cost of landscaping of 1 sq.feet = $10

Cost of landscaping of x sq.feet = $10x

So, Total charge by company A = 250+10x  ---1

Company B

Monthly consulting fee = $90

Cost of landscaping of 1 sq.feet = $12

Cost of landscaping of x sq.feet = $12x

So, Total charge by company B = 90+12x   ---2

Now we are supposed to find  how many square feet of landscaping will the two companies charge the same amount

So, Equate 1 and 2

[tex]250+10x=90+12x\\160=2x\\80=x[/tex]

So, the two companies charge the same amount for 80 sq.feet

Total charge by company A for 80 sq.feet = 250+10(80)= $1050

Total charge by company B for 80 sq.feet = 90+12(90)=$1170

Step-by-step explanation:

I will assume that the numbers are [tex]1\frac{1}{4}[/tex] and [tex]8\frac{3}{4}[/tex]. To find the answer, we can do:

[tex]8\frac{3}{4} / 1\frac{1}{4}\\ = \frac{35}{4} / \frac{5}{4} \\= \frac{35}{4} * \frac{4}{5}\\= \frac{35}{5}[/tex]

Answer:

The mean size of the shoe is 7.

Step-by-step explanation:

We are given the shoe size for all the pairs of shoes in a person closet below;

X = 7, 7, 7, 7, 7, 7, 7, 7, 7, 7.

And we have to find the mean of the data.

Let X = shoe size for all the pairs of shoes

As we know that the mean of any discrete data is given by the following formula;

               Mean, [tex]\bar X[/tex] = [tex]\frac{\text{Sum of all the observations}}{\text{Total number of observations}}[/tex]

Here, the number of observations = 10

                              =  [tex]\frac{7+7+7+7+7+7+7+7+7+7}{10}[/tex]

                              =  [tex]\frac{70}{10}[/tex]  = 7

Hence, the mean size of the shoe is 7.

Answer:

49 feet

Step-by-step explanation:

We solve for this using proportion

Height of Jack's house = ?? = Y

Length of the shadow of Jack's house = 56 feet

Height of a tree = 21 feet

Length of the shadow of the tree = 24 feet

Height of Jack's house/ Shadow of Jack's house = Height of a tree/ Shadow of the tree

Y/56 = 21/24

Cross Multiply

24 × Y = 56 × 21

Y = 56 × 21/24

Y = 1176/24

Y = 49 feet

Therefore, the height of Jack's house is 49 feet

Answer: 13.5π≈42.41

Step-by-step explanation:

Basically it is asking for the circumference of this cylinder.

#1 Find the circumference of the circle base

Formula to use: 2πr

2πr=2π(1.5)=3π

---------------------------

#2 Find the area of the circle base

Formula to use: πr²

πr²=π(1.5)²=2.25π

--------------------------

#3 Find the area of body of the cylinder

Formula to use: lw

300cm=3m

l (length)= 3π (since the body of the cylinder the basing on the circumference of the circle base)

w (width)= 3

lw=3π×3m=9π

----------------------------

#4 Add all of them together

There are 2 base and one body

2.25π×2+9π=13.5π

The number -1/3 belongs to the set of rational numbers.

A number -1/3 is given in the question.

We have to find out that this number belongs to which set of numbers.

What is a rational number ?

A rational number is one which can be expressed as fraction p/q of two integers where p is a numerator and q is a non-zero denominator i.e., q ≠ 0.

Let's check -1/3 belongs to which set,

We know that ,

Natural numbers are the counting numbers , so -1/3 can't be a natural number.

Also ;

-1/3 can't be a irrational number because as this number is a finite number.

Let's check if it is a rational number ;

We know that rational number can be expressed in form of p/q.

Hence ;

[tex]\frac{p}{q}[/tex] = [tex]\frac{-1}{3}[/tex] , where ; p = -1 and q = 3 i.e., q ≠0

Thus , the number -1/3 belongs to the set of rational numbers.
