I need the base and hight

Mathematics
1 answer:
iris [78.8K]3 years ago
4 0

Answer:

Height = 5 and Base = 10

Step-by-step explanation:

The base of the parallelogram is twice the perpendicular height of the parallelogram. The area of the parallelogram is 50 cm².

Formula for area of parallelogram = base × height

Base = 2h

Height = h

∴ Area = 2h × h = 50

Solution:

2h × h = 50

2h² = 50

\frac{2h^{2} }{2} = \frac{50}{2}

h² = 25

\sqrt{h^{2} } = \sqrt{25}

h = 5

∴ height = 5 and base = 2(5) = 10

A person on a moving sidewalk 21 feet in 7 senconds the moving sidewalk has a lenght of 180 feet. How long will it take to move
aliina [53]

Answer:

He will take 60 seconds to move from one end of the sidewalk to other.

Step-by-step explanation:

Given:

A person on a moving sidewalk,

21 feet in 7 seconds

Then 180 feet

To Find:

Total time =?

Solution:

Speed:

Speed is defined as the rate of distance covered in per unit time.

It is given as

\textrm{Speed }=\dfrac{\textrm{Distance}}{Time}

Substituting the given values we get

\textrm{Speed }=\dfrac{21}{7}=3\ m/s

Now, With this speed if he walk 180 feet then the time is

\textrm{Time}=\dfrac{\textrm{Distance}}{Speed}

Substituting  Speed and Distance we get

\textrm{Time}=\dfrac{180}{3}=60\\\\Time=60\ s

He will take 60 seconds to move from one end of the sidewalk to other.

PICTURE) Could someone please correct my answer and explain 6 for me marking brainliest
Gnesinka [82]

Answer:

For number 5, it is D

For number 6, it is A

Step-by-step explanation:

For number 5, we have the dimensions options here.

We first need to check to see if all the choices give the perimeter of 34, as sometimes there are trick answers.

We know the 34 is the perimeter because we are looking for area, so we add the two given numbers and double it to find the perimeter since we have the length and width.

*(Formula for perimeter is 2(L + W)  )

(I already checked them all, and they all give to be 34 so they are all safe.)

Then we find the areas of each.

*(Formula for area is L * W   {the " * " symbol represents multiplication.)

We multiply 12 by 5 to get 60.

We multiply 13 by 4 to get 52.

We multiply 10 by 7 to get 70.

We multiply 9 by 8 to get 72.

Since we are looking for the greatest area, we look for the greatest number, which is the 72.

Therefore the 9 by 8 option, or D is correct.

For number 6, we are looking for the minimum perimeter and we have the area, so we set the same thing up except modified slightly.

We first check if all the areas are 64 to look for a trick answer.

We multiply 8 by 8 to get 64.

We multiply 1 by 64 to get 64.

We multiply 6 by 6 to get 36. (WHAT?!!?!! omg me big brain lolza. {nah jk})

We multiply 32 by 2 to get 64.

So we know the 6 by 6 option or C is wrong.

Then we look for the perimeters of the dimension solutions.

(This will skip C so it will go A, B, and then D, since we know C is incorrect and is unrelated now.)

2 ( 8 + 8 ) =  32

2 ( 1 + 64 ) =  130

2 ( 32 + 2 ) =  68.

Since we are looking for the smallest perimeter, it is the smallest answer this time.

So it must be A, since 32 is the smallest.

Hope this helps!

Show 46/200 on the hundredths grid. then write the fractions as a demical
SSSSS [86.1K]
If we want to has 100 in the denominator we have to divide numerator and denominator by 2. Then total value of fraction doesnt change.
\frac{46}{200}= \frac{46:2}{200:2}= \frac{23}{100}
Now read the fraction, its 23 hundreds, now just write as decimal, so, 0.23
