the length of the hypotenuse of a right triangle is 15 and the length of one leg is 12 find the length of the other leg​

Answers

Answer:

the other leg would be 12

hypothenuse = 15
one side length = 12
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 81
b = squareroot 81

Is 0.3 the multiplicative inverse of 3 1/3? Why or why not?

Chapter : Rational Numbers ​

Answers

Answer:

3 1/3 = 10/3

0.3 = 3/10

a * 1/a =1

then 1/a is multiplicative inverse of a

0.3* 3 1/3 = 3/10 * 10/3 =1

0.3 is multiplicative inverse of 3 1/3

Step-by-step explanation:

Answer:

3 1/3 = 10/3

10.3 = 0.3 = 3 1/3

x * 1/x = 1

∴ yes, the multiplicative reverse of 3 1/3 is 0.3

Manuel bought 9 pounds of apples.
He has eaten 3
4 of a pound so far and has
$15 worth of apples left. Write and solve an
equation to find the cost of the apples per
pound to the nearest dollar. How much did
the apples cost per pound?

Answers

Answer:

1) Since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left   (9  - 0.75  = 8.25)

 2) Let's call "x" the cost of 1 pound of apples

 3) (8.25)*(x) = $15

 4) x = $1.81818    rounded to the nearest dollar is $2 / pound

i have to determine if DE is parallel to AC

Answers

Answer:

Triangle BDE and triangle BAC are similar triangles

Hence, two lines DE and AC are parallel to each other

Step-by-step explanation:

For proving that DE is parallel to AC, we are required to prove that triangle BDE and triangle BAC are similar triangles

The ratio of sides of both the triangle must be equal to each other

Hence

[tex]\frac{BE}{DB} = \frac{BC}{BA} \\\frac{16.1}{28} = \frac{20.7+16.1}{64}\\0.575 = 0.575[/tex]

and angle B is common.

Hence the two triangles are similar.

Therefore angle BDE and angle BAC are equal like wise angle BED and angle BCA are equal.

Thus, the two lines DE and AC are parallel to each other

Henry can write 5 pages of his novel in 4 hours. At this rate, how many pages can Henry write in 8 hours?

Answers

Answer:

Henry can write 10 pages in 8 hours.

Step-by-step explanation:

Our unit rate (number of pages in a given number of hours) is

5 pages

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

   4 hrs

It is not necessary to perform the indicated division.  Just multiply this unit rate by '8 hours':

5 pages

-------------- * 8 hrs = 10 pages

   4 hrs

Henry can write 10 pages in 8 hours.

10 pages if he can write 5 pages in 4 hours then you double that for 8 hours

I got x=10

Step-by-step explanation:

Step 1

Everything must add up to 180

180= 6x - 6 + 7x + 1 +55

Step 2

Combine everything

6x + 7x = 13x

-6 + 1 +55 =50

180 = 13x + 50

Step 4

Subtract. 180 -50

130 = 13x

Step 5

Divide 130/13

X=10

6(10) -6 = 54

7(10) + 1=71

Frank designed a net for a storage shed that he is going to construct out of metal. The design consists of a square base and four square sides, plus four triangular parts that make up the roof.

He had 250 square feet of metal to use to build the shed. (What is the surface area of the storage Shed that Frank Designed?) (Does Frank have enough metal to construct his design yes or no?)

Answers

Answer:

Yes, Frank does have enough, he has 250 metal and only has 228 surface area.

Step-by-step explanation:

You take all the triangles (4) and multipy 4 x 6 (24) then divide that by 2 (12) so now you know all the triangles are equal to 12. Then the squares, you multiply 6 x 6 (36) now you know all the squres are equal to 36 and then you add 12 + 12+12+12+36+36+36+36+36 and then you get 228.

if it wants the measurement of arcJK....

Answer:

ArcJK= 128

Step-by-step explanation:

Circle is 360 degrees

<KL is the diameter which is a straight line equals 180 degrees

Since <KLis also a central angle arcKL equals 180

Take <K (26) and times by two cause its an inscribe angle, 26*2=52

arcJL=52

add both arcKL and arcJL together: 180+52=232

then you take 360-232=128

and 128 is KLarc
