Find the angle measures

Answer:

It might be 8.8889% (Not completely sure)

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Answer: [tex]y=-5x+21[/tex]

Step-by-step explanation:

In slope intercept form : y=mx+c , m= slope , c= y-intercept.

Let [tex]L_1[/tex] be the line passing through (5, -4) and perpendicular to [tex]L_2: 2x-10y=0[/tex].

Rewrite [tex]L_2[/tex] in slope-intercept form

[tex]10y=2x\Rightarrow\ y=0.2x+0[/tex]

Here, Slope of [tex]L_2[/tex] = m = 0.2  

Let n be slope of [tex]L_1[/tex] .

Then  [tex]m\times n=-1[/tex]   [Product of slopes of perpendicular lines is -1.]

[tex]\Rightarrow\ n=\dfrac{-1}{m}=\dfrac{-1}{0.2}\\\\\Rightarrow\ n=-5[/tex]

Equation of a line that passes through (a,b) and have slope 'm' is given by :-

[tex](y-b)=m(x-a)[/tex]

So, Equation of [tex]L_1[/tex] :

[tex](y-(-4))=-5(x-5)\\\\\Rightarrow\ (y+4)=-5x+25\\\\\Rightarrow\ y=-5x+21[/tex]

Answer:

x²+8x

Step-by-step explanation:

area of rectangle

l×w

(x+8)×x

x²+8x

The area of the rectangle is [tex]X^2 + 8X[/tex].

To find the area of a rectangle, we multiply its length by its width.

In this case, the length is (X + 8)

and the width is X.

so, we have,

Area = Length * Width

Area = (X + 8) * X

To simplify the expression, we need to distribute the X through the parentheses:

Area = X * X + 8 * X

Area = [tex]X^2 + 8X[/tex]

So, the area of the rectangle is [tex]X^2 + 8X[/tex].

Answer:

a. $12,600

b. $21

c. $19

Step-by-step explanation:

a) The cost is $3000 plus $16 per book

For 600 books, we have

3000 + 16(600)

= 3000 + 9600 = $12,600

b) Cost per book will be;

12,690/600 = $21

c) for 1000

= 3000 + 16(1000)

= 3000 + 16,000 = 19,000

cost per book is 19,000/1000 = $19

Answer & Step-by-step explanation:

First write the line equation.

y=mx+b is the format where m=slope, b= y intercept

y=-2x-3

plug each x in to see if they match the point

y= -2(-2) -3 = -4 - 3 = -7 ; the point is (-2,0) so NO

y= -2(-1.5) -3= 3-3 = 0; point is (-1.5, 0) so YES it matches

y= -2(-6) -3 = 12-3 = 0; point matches so YES

y= -2(2) -3 = -4-3 = -7; point is (2, -3) so NO

y = -2(3) -3 = -6-3= -9; point matches so YES

y= -2(-4)-3 = 8-3 = 5; point is (-4, 4) so NO

(-1.5, 0) & (-6, 9) & (3, -9)

Step-by-step explanation:

Fraction before painting = 5/6

Fraction left after painting = 11/30

Fracrion used = difference of the fraction before painting and fraction left after painting

Fraction used = 5/6 - 11/30

Lowest common factor of 6 and 30 = 30

5/6 - 11/30 = (25 - 11) / 30 = 14/ 30

Fraction used = 14/30 = 7/15

Answer:

-2.1f-17

Step-by-step explanation:

combine like terms

Answer:

-2.1f-17

Step-by-step explanation:

1. Combine like terms

Like terms are those that either have the same variable, degree, or no variable at all.

Here, -2.5f and 0.4f and -14 and -3 are like terms. -2.5f and 0.4f are like terms because they both have f beside them. The reason -14 and -3 are like terms is because they both stand alone with no variables.

Combining like terms means to either add or subtract them from each other depending on their signs.

Just think of them as two separate problems for now.

-2.5f + 0.4f = ?

add these two together to get -2.1f

-14-3

Subtract these to get -17.

2. Put the expression back together: -2.1f-17

Answer:

The perimeter or circumference of a half mirror = 37.68 cm

Step-by-step explanation:

We know that the perimeter of a circular shape is called the 'circumference', with the formula

When the mirror is cut into half, the diameter gets half as well.

We know that radius = r = diameter / 2 = 12/2 = 6 cm

Thus, the perimeter of half of the mirror  = C = 2πr

                                                                           = 2(3.14)6

                                                                            = 37.68 cm

Therefore, the perimeter or circumference of a half mirror = 37.68 cm

Answer:

  18

Step-by-step explanation:

There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical  music, 13.

  4 + 3x = 13

  3x = 9 . . . . . subtract 4

  x = 3 . . . . . . divide by 3

__

We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.

  like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18

18 students like two types of music only.

Answer:  [tex]385cm^{2}[/tex]

Step-by-step explanation:

given data:

AB= 10 cm.

BC = 22 cm.

volume of a cylinder V = [tex]\pi r^{2} h[/tex]

h = 10.

solution

base of the circumference = 22cm

circumference of a circle = [tex]2\pi r[/tex]

r = radius is unknown.

[tex]2\pi r = 22[/tex] .........................eq1

where [tex]\pi = \frac{22}{7}[/tex] insert this into eq1.

[tex]2* \frac{22}{7}* r = 22[/tex]

[tex]\frac{44}{7} r = 22[/tex]

[tex]r = \frac{22}{\frac{44}{7} }[/tex]

[tex]r= 3.5cm[/tex]

next we solve for the volume of the cylinder.

recall   [tex]V = \pi r^{2} h[/tex]

h = 10cm

r = 3.5cm

[tex]V = \frac{22}{7} * (3.5)^{2} *10[/tex]

[tex]V = 385cm^{2}[/tex]

Answer:

40 students

Step-by-step explanation:

We do not count the counselors or the principal because they are not students, so we do 83 - 3 = 80, now it is just simple division, for every student there is a parent, so we divide 80 in half, 80 / 2 = 40 students :D

The light will travel 5,580,000 miles in 30 seconds.

To understand the calculations, check below.

The distance traveled by light is represented by function.

                   [tex]d(t)=186,000t[/tex]

To find the distance traveled by light in 30 seconds.

Substitute t=30 in the given function.

            d(30) = 186,000 × 30

             d(30) = 5,580,000 miles.

Hence, the light will travel 5,580,000 miles in 30 seconds.

Option C

Step-by-step explanation:

Since, measure of all sides of the triangle has been given in the picture,

By applying cosine rule in the given triangle,

AC² = AB² + BC² - 2(AB)(BC)cos(B)

11² = 16² + 16² - 2(16)(16)cos(B)

121 = 256 + 256 - 512.cos(B)

121 - 512 = - 512.cos(B)

cos(B) = [tex]\frac{391}{512}[/tex] = 0.763672

B = [tex]cos^{-1}(0.763672)[/tex]

B = 40.2°

Therefore, measure of angle B is 40.2°.
