This question is incomplete. Hereis the complete question:

Which of the following options have the same value as 65% of 20 ?

(A) 0.65⋅20 (B) 65/100 divided by 20 (C) 65/20 * 100 (D) 65 * 20

Answer:

The correct answer is option (A) 0.65⋅20

Step-by-step explanation:

In this case they are asking us for an expression that is equivalent to 65% of 20. They are<u> not asking us what is the value of that operation</u>.

When we do a percentage calculation we can do it in two ways.

Let's see each one of them:

. (65 * 20): 100 =

1300: 100 = 13

. 0.65. 20 = 13

As we can see both ways we get the same result.

Given this information we can say that the correct answer is option A.

Emily's family loves to work together in the garden. They have a slight preference for flowers, as 60percent of their plants are

DaniilM [7]

Answer:

There are 20 vegetable plants in garden.

Step-by-step explanation:

We are given the following in the question:

Percentage of flowers = 60%

Percentage of vegetable = 40%

Number of plants in garden = 50

Number of vegetables in garden =

$40\% \times \text{Number of plant}\\\\= \dfrac{40}{100}\times 50\\\\= 20$

Number of flowers in garden =

$60\% \times \text{Number of plant}\\\\= \dfrac{60}{100}\times 50\\\\= 30$

Thus, there are 20 vegetable plants in garden.

Find a line that lies entirely in the set defined by the equation x2 + y2 − z2 = 1.

RUDIKE [14]

Answer:

$x=1\,,\,y=t\,,\,z=t$

Step-by-step explanation:

A line is a one-dimensional figure that has no thickness and extends infinitely in both directions.

A line segment is a line that has two end-points and a ray is a line that has one end-point.

Given equation is $x^2+y^2-z^2=1$

To find : a line that lies entirely in the set defined by the given equation.

Solution:

Take $x=1\,,\,y=t\,,\,z=t$

Check:

$L.H.S=1^2+t^2-t^2=1+0=1=R.H.S$

Therefore, $x=1\,,\,y=t\,,\,z=t$ satisfy the given equation.

City planners are creating a 3-dimensional model of a city park to find the best placement for a new tennis court. The city park

inn [45]

First, divide the original measurements with the scaled ones. You'll get the same answer meaning that is the scale used by the model.
1500 ft. ÷7.5 ft = 200
600 ft. ÷ 3 ft. = 200

To simply check, if you divide 1500 with 200, the answer is 7.5 and 600 divided by 200 is 3.
To find the scaled dimension of the tennis court with actual dimension of 120 ft by 60 ft, divide both values with the scale used in the model which is 200.

120 ft. ÷ 200 = 0.6 ft
60 ft. ÷ 200 = 0.3 ft

The dimension of the tennis court in the scaled model is 0.6 ft long and 0.3 ft. wide.
