Answer:

24.359

Step-by-step explanation:

The height is opposite of the 77 so we are using sin. The length of the ladder is the hypotenuse.

sin(77°)=height/25     Set up equation sin=height/hypotenuse

25*sin(77°)=height     Multiply both sides by 25

25*.96437=height

height=24.359

The equivalent expression using the distributive property is 6(7x + 2)

From the question, we have the following expression

42x + 12

Rewrite the given expression as follows

This is represented using

(42x + 12)

Factor out 2 from the expression

So, we have the following representation

42x + 12 = 2(21x + 6)

Factor out 3 from the expression

So, we have the following representation

42x + 12 = 2 * 3(7x + 2)

Evaluate the products

42x + 12 = 6(7x + 2)

The above represents the equivalent expression

Answer:

21st 22nd are equal so ×=0

Answer:

9514 1404 393

Answer:

 $67,200

Step-by-step explanation:

The amount if interest is given by the formula ...

I = Prt

where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.

 P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025

 P = $67,200

The amount invested was $67,200.

Step-by-step explanation:

Answer:

A) 0.5

B) 10

Step-by-step explanation:

A) First, you need to Combine Like Terms on the right side of the =

98-248 = -150

Now, you need to Isolate the variable by getting rid of the -178. What you do to one side, you must do the the other.

56a-178(+178) = -150(+178)

56a = 28

Finally, you must remove that 56 on the a. Since it stands for 56 x a, you must do the same you did with the -178 except with Division.

56a/56 = 28/56

a = 0.5

B) Combine Like terms

640+70 = 710

Isolate the variable

710(-20) = 69y+20(=20)

690 = 69y

Remove the 69 with division

690/69 = 69y/69

10 = y

Answer:

-1/5

Step-b-1/5y-step explanation:

The rule for a perpendicular slope of a line is -1/s

In this case, we find the slope of the line first.
5x - y = -7
-y = -5x - 7
y = 5x + 7

The slope is 5, so -1/(5) is the slope of the perpendicular line.

Answer: [tex]\frac{0}{24}[/tex]

Step-by-step explanation:

The slope is [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex], or reverse: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

If we substitute, we get that [tex]\frac{2-2}{6-(-18)}[/tex].

The Amount of money that she received at the end of the read is $4024, the relationship between the number of years Ira has his money invested and the balance in any year differs by $24 which is the simple interest.

Amount invested by Ira = P = $4000

The rate of Interest (r) = 0.6 %

Time period (t) = 1 year.

The simple interest is given by,

[tex]S.I. = \frac{P*r*t}{100}[/tex]

Now, putting the values in the formula, we get:

[tex]S.I. = \frac{4000*0.6*1}{100} =24[/tex]

Hence, the simple interest will be $24

Now, the Amount/balance that she received in the year is A = P +S.I

A = P+S.I.

A = 4000 +24 = $4024

Answer:-5/1

Step-by-step explanation:

down 5 and over 1

to get the slope, find a spot on the graph and then go 1 to the right and read how much the graph went up or down.
on 5) you see it did neither, so m=0
when the graph goes up, m is positive, when it goes down, m is negative.
so on graph 1, you have 2 dots.
you go 2 right, and 4 down. when the dots are not 1 apart (counting going right)  then divide by the steps you went right.
4 divided by 2 is 2.
-> graph went down, slope for 1) is m = -2

graph 2) you go 2 right and 2 up, 2/2 = 1. you went up, so m is positive and m = 1 for this graph.

3) is undefined because it doesn't go anywhere when you go right, it's 100% vertical

4) m = -5 because you went 1 right and 5 down

5) you go 6 right between the dots and 4 down. m is negative because it went down, not up. so m = -(4/6)

The height of the cone is 580.36 cm.

The curved surface area of the cone is given by,

[tex]A = \pi \sqrt{h^{2} +r^{2} }[/tex]

Squaring both sides, we get :

[tex]A^{2} =\pi ^{2} (h^{2} +r^{2} )[/tex]

Now, it is given that the height of the cone is h,

The area of the cone = 550 [tex]cm^{2}[/tex]

And the radius of the cone = 7cm,

Putting these values in the given formula, we get,

[tex]A^{2} =\pi ^{2} (h^{2} +r^{2} )[/tex]

[tex]550^{2} = \pi ^{2} * ( h^{2} +7^{2} )\\[/tex]

The solution when Kaitlyn has at least five purses using signs and number is N ≥ 5

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other.

When two expressions are equal, we use the equal sign ( = ). But when we are trying to compare two values or expressions, we use the inequality signs like greater than (>), less than (<), greater than or equal to ( ≥ ) and less than or equal to (≤)  

Given that: Kaitlyn has at least five purses

In order to solve this problem with signs and number, you will make use of the inequality that explains the situation:

Let the number of purses be N

Kaitlyn having at least five purses means she has 5 purses or more. Using inequality, the number of purses is greater than or equal to 5. Thus:

N ≥ 5

Therefore, the solution using signs and number is N ≥ 5

The equation of the given straight line is y = 3x.

We are given a graph. The graph shows a straight line. Several points are marked on the line in the graph. The coordinates of two such points are (1, 3) and (2, 6). We need to find the equation of the straight line.

The equation of the straight line can be found using the two-point form of a line. The equation is solved below.

(y - y1) = [(y2 - y1)/(x2 - x1)]×(x - x1)

(y - 3) = [(6 - 3)/(2 - 1)]×(x - 1)

y - 3 = 3(x - 1)

y = 3x - 3 + 3

y = 3x

Hence, the equation of the line shown in the graph is y = 3x.

If the motor shaft rotated at 900 rpm, the speed of the larger gear will be 100 rpm.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

it is given that, A 35-tooth gear on a motor shaft drives a larger gear having 63 teeth and the motor shaft rotated at 900 rpm.

The number of teeth on the smaller gear,n₂ = 35

The number of teeth on the larger gear,n₁ = 63

The gear ratio is obtained as,

n₁/n₂=63/35

n₁/n₂=9:5

If the motor shaft rotated at 900 rpm, The speed of the larger gear is,

=900 rpm / 9

=100 rpm

What are Parallel Lines?

What is Point-Slope Equation of Line?

Here, it is given that the equation of the line parallel to the given straight line is [tex]y=\frac{3}{2} x-6[/tex]  ----(1)

We know that the slope of parallel lines is equal.

So, the slope of (1) will be equal to the given line.

Writing (1) in the form of [tex]y=mx+c[/tex], we get

Slope, [tex]m=\frac{3}{2}[/tex]

Using the Point-Slope Equation of the line, we have

[tex]y-y_{1}=m(x- x_{1})[/tex]

Now, substituting the point (-6,5) in the place of [tex](x_{1}, y_{1})[/tex], we get

[tex]y-5=\frac{3}{2} (x- (-6))\\\implies 2(y-5)=3(x+6)\\\implies 2y-10=3x+18[/tex]
