Elena’s bedroom door is 0.8 m wide. How wide should the door be on the scale drawing, if the ratio is 1 to 50?

arlik [135]

We are given Elena’s bedroom door's width = 0.8 m.

Also the scale drawing is in the ratio of 1 to 50 that is 1/50.

In order to find the width of scale drawing, we need to multiply original width of the door by 1/50.

If we multiply 0.8 by 1/50, we get

0.8 × 1/50 = 0.8/50 = 0.016 meter.

So, we can say 0.016 meter wide should the door be on the scale drawing, if the ratio is 1 to 50.

A water truck is filling a swimming pool. The equation that represents this relation is y=18.25x where y is the number of gallon

QveST [7]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, however, one of the requirements of this question while I searched, was to make a table and sketch the equation.

If this is the case, then, all you need to do is take the equation, Assume some values for x, and compute the values of y. Then, you can do the graph.

I begin with value from 0 to 10.

This is the example of calculations:

x = 0

y = 18.25*0 = 0

for x = 0, we get y = 0. For x = 2:

y = 18.25 * 2 = 36.5

If we keep doing this, we should get a straight line. See the graph and attached table. If the question is asking another thing, then please get back to me to answer it.

Solve the equation and enter the value of x below. -4(x - 5) = 60

dsp73

Answer:

The value of x is 10.

Step-by-step explanation:

By question,

-4(x - 5) = 60

or,-4x + 20 = 60

or,-4x = 60 -20

or, -4x = 40

or, x =40/-4

Hence,x=10

A geometric series has second term

neonofarm [45]

Answer: 243/5 = 48.6

Step-by-step explanation:

a₁, 375, a₃, a₄, 81 , a₆

First, let's find the ratio (r). There are three multiple from 375 to 81.

$375r^3=81\\\\r^3=\dfrac{81}{375}\\\\\\r^3=\dfrac{27}{125}\qquad \leftarrow simplied\\\\\\\sqrt[3]{r^3} =\sqrt[3]{\dfrac{27}{125}}\\ \\\\r=\dfrac{3}{5}$

Next, let's find a₆ which is one multiple from 81.

$a_6=81\bigg(\dfrac{3}{5}\bigg)^1\\\\\\.\quad =\large\boxed{\dfrac{243}{5}}$
