Answer 2

Answer:

Perimeter:40 Area:60

Step-by-step explanation:

To find the perimeter add all the sides

15+17=32   32+8=40

To find the area it is A=1/2bh (base times height times 1/2)

A=1/2(15)(8)

A=1/2(120)

A=60

When doing the area of a triangle, think of it as finding the area of a rectagle, then cutting it in half.

A book has 240 pages and each day 10 pages are
read. The number of pages left, p, is given as a
function of d, the time in days, where
p = 240 – 10d . Graph the equation, then use its
x-intercept to determine when the book will be
finished?

Answers

Answer:

24 days is the answer

Step-by-step explanation:

If the book is 240 pages and each day 10 pages are read you could easily divide 240 by 10 and get 24.   However, you need to use the formulas for your answer I suppose.  So, to get the  x-intercept this is what you do.  You have to use the slope-intercept form y = mx+b  where m=-10 and b = 240 so you end up with y = -10x+240

So now you solve for x-intercept

0 = -10d+240

subtract 240 from both sides so       0 = -10d + 240

                                                         -240              -240

you are left with -240 = -10d.  Now simplify and divide each term by -10     -240/-10 = 24 and -10d/-10 = d

   you are left with d = 24 or 24 = d

You graph the equation by placing a point at  240 on the y axis and 24 on your X-axis.

if m2 = 125, m12= 37 and m18 = 102, find the measure of each angle

Answers

Answer/Step-by-step explanation:

Given:

m<2 = 125°

m<12 = 37°

m<18 = 102°

a. m<1 + m<2 = 180° (linear pair)

m<1 + 125° = 180° (substitution)

m<1 = 180° - 125°

m<1 = 55°

b. m<3 = m<18 (alternate exterior angles)

m<3 = 102° (substitution)

c. m<4 + m<3 = 180° (linear pair)

m<4 + 102° = 180° (substitution)

m<4 = 180° - 102°

m<4 = 78°

d. m<5 = m<2 (vertical angles)

m<5 = 125° (substitution)

e. m<6 = m<1 (vertical angles)

m<6 = 55° (substitution)

f. m<7 = m<12 (alternate angles)

m<7 = 37° (substitution)

g. m<8 + m<12 + m<13 = 180° (sum of triangle)

m<12 = 37° (given)

m<13 = m<18 = 102° (vertical angles)

m<8 + 37° + 102° = 180° (substitution)

m<8 + 139° = 180°

m<8 = 180° - 139°

m<8 = 41°

h. m<9 = m<18 (corresponding angles)

m<19 = 102° (substitution)

i. m<10 = m<6 (alternate interior angles)

m<10 = 55°

j. m<11 + m<6 + m<7 = 180° (sum of triangle)

m<11 + 55° + 37° = 180° (substitution)

m<11 + 92° = 180°

m<11 = 180° - 92°

m<11 = 88°

k. m<13 = m<18 (vertical angles)

m<13 = 102°

l. m<14 = m<4 (corresponding angles)

m<14 = 78°

m. m<15 = m<5 (corresponding angles)

m<15 = 125°

n. m<16 = m<6 (corresponding angles)

m<16 = 55°

o. m<17 = m<14 (vertical angles)

m<17 = 78°

K. A quadrilateral has a total angle measure of 360. We know that two of the angles are 90, so we can subtract 180 from that. We’re left with 180. So we can make it into and equation. X+2x=180. Simplify and solve, and you get that x=60.

L. Again, a quadrilateral has a total of 360. So we can subtract the right angle from that and get 270. Put it into and equation, and you get x+2x+3x=270. Simplify and solve, and you get that x=45.

well where is does the step not make sense?

remember cos(pi) = -1 and sin(pi)=0

that means step 1 is strange... it didn't distribute properly

it should have been:

cos(pi) - cos(A)

hope that helps! ^-^

The error is made at step 1). The correct trigonometric identity is cos(π - A) = cosπcosA + sinπsinA.

Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined.

A summer camp has 720 ft of float line with which to rope off three adjacent rectangular areas of a lake for swimming​ lessons, one for each of three levels of swimming ability. A beach forms one side of the swimming areas. Suppose that the width of each area is x feet. Answer parts​ a) through ​c).

Answers

Step-by-step explanation:

Kindly find attached a detailed image to better understand the solution to this problem.

given that the total length of the line is 720ft

and also the line is divided into three sections

This means that the line will also be divided into three parts

720/3= 240feet so that a section will have two sides that are 240ft since the section forms a rectangular shape.

now for the other two sides

the total length of the rope is  = one length size of the rectangle+ 4 width size of the rectangle

one width size of the rope is x

then 4 width size is 4x

720=length of rectangle +4x

length of rectangle= 720-4x

area of a rectangle is =length *width

area of rectangle is =  (720-4x)*x

Hence the function A=  (720-4x)x can be used to solve for the area of the rectangle.
