The area of a rectangular garden is 8330 m².
If the length of the garden is 98 m, what is its width?

Answers

9514 1404 393

Answer:

  85 m

Step-by-step explanation:

The area is the product of length and width. This can be used to find the width.

  A = LW

  8330 m² = (98 m)W . . . . . . . . . . . fill in the given values

  8330 m²/(98 m) = W = 85 m . . . . divide by the coefficient of W

The width of the garden is 85 meters.

find the whole quantity if 5 percent of it is 500​

Answers

Answer:

10,000

Step-by-step explanation:

500/0.05= 10,000

You take the amount you are given divided by the decimal form of the percentage you are given to find the answer.  It's a reverse from the way you find 5% of 10,000.

0.05=5%

Check your work: 10,000*5%= 500

use the geometric mean theorems to find AC and BD. BA=20 BC=15

Answers

Step-by-step explanation:

first, you use the pythagorean theorem to find the missing side of the original and big triangle.

[tex]20 {}^{2} + 15 {}^{2} [/tex]

next, you simplify these into actual numbers

[tex]400 + 225[/tex]

after, you add these numbers together and find the square root.

[tex]\sqrt{625} = 25[/tex]

you have the answer for AC. next you need to find BD. of you line up BC with BD, BC would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for BD- that's just me- but I'm not sure how to exactly find it.

The requried Measure of the BD and AC in the given question is 17.32 and 25 respectively.

What is the geometric mean theorem?

The geometric mean theorem for a right triangle states that the length of the altitude (height) to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.

Here,
From the triangle, following the Geometric mean theorem,

BD = √[AB×BC]
BD = √[20×15]
BD = √17.32

Now,
Applying the Pythagorean theorem to find AC,
AC = √15² + 20²
AC = 25

Thus, the requried Measure of the BD AC in the given question is 17.32 and 25 respectively.

Triangle QRS was dilated using the dilation rule DP,4.

Point P is the center of dilation. Triangle Q R S is dilated to create triangle Q prime R prime S prime. The length of P R is 3.

What is PR'?

6 units
9 units
12 units
15 units

Answers

Using the dilation rule, the length of P'R' is: C. 12 units.

What is Dilation?Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.

Given that the scale factor of dilation is 4, and PR is 3.

Therefore:

P'R' = 4(PR)

P'R' = 4(3)

P'R' = 12 units.

Therefore, using the dilation rule, the length of P'R' is: C. 12 units.

Answers

Answer:

The answer is 12.

Step-by-step explanation:

We need to find the value of the given expression 6a+4b−6 when a = 1 and b = 3

Put a = 1 and b = 3 in the above expression.

6a+4b−6 = 6(1) +4(3) -6

= 6+12-6

= 12

So, the value of the given expression is equal to 12.

[tex]x^{2} +9y^{2} =1[/tex] is an ellipse. The line y=mx+2 is tangent to the ellipse. Determine the value of ([tex]m^{2}[/tex]). Express your answer as an integer or as a common or improper fraction.

Answers

Answer:

  m^2 = 35/9

Step-by-step explanation:

The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.

  x^2 +9(mx +2)^2 = 1

  x^2 +9(m^2x^2 +4mx +4) = 1

  (9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms

__

Then the discriminant is ...

  (36m)^2 -4(9m^2 +1)(35)

We want it to be zero, so we have ...

  1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses

  36m^2 = 140 . . . . . . . . . . . . . . . add 140

  m^2 = 140/36 . . . . . . . . . . . . divide by 36

  m^2 = 35/9
