Solve the formula d=rt for t

Answers

Answer 1

Answer:

Answer:

t = $(d)/(r)$

Step-by-step explanation:

Given

d = rt , or

rt = d ( solve for t by dividing both sides by r )

t = $(d)/(r)$

Answer 2

Answer:

Answer:

Can confirm that the correct answer is t=d/r

Step-by-step explanation:

hope u have a nice day

the length of the flower garden is 3 times as great as the width. what are the dimensions of the flower garden

Answers

Without any more information we can't find the actual numerical representation of the length and width but we can give an expression that will allow us to find them...

We let the width equal x, so the length is 3x. That would be the dimensions...

length = 3x
width = x

So to find perimeter the expression would be

2(3x) + 2(x) =
6x + 2x =
8x

For the area it would be

a= length × width
a = 3x × x
a = 3x^2

Evaluate sinA for the triangle shown

Answers

The value of sinA in the triangle is 0.6. Then the correct option is A.

What is trigonometry?

Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.

In the given triangle base is 8 and the perpendicular is 6 units. To calculate sinA we need hypotenuse and then use the Pythagorean theorem.

H² = P² + B²

H² = 6² + 8²

H² = 36 + 64

H² = 100

H = 10

The angle sinA is the ratio of perpendicular and hypotenuse.

sinA = P / H

sinA = 6 / 10

sinA = 0.6

Hence, the correct answer is option A.

Graph f(x) = (1/3)^x+1

Answers

Answer:

The graph is attached below.

Step-by-step explanation:

Given the function

$f\left(x\right)\:=\:\left(1/3\right)^x+1$

Exponentiation function have a horizontal Asymptotes.

Finding the horizontal Asymptotes

$\mathrm{Exponential\:function\:of\:the\:form}\:f\left(x\right)\:=c\cdot \:n^(ax+b)+k\:$

$\mathrm{has\:a\:horizontal\:asymptote}\:y=k\:$

$k=1$

$\mathrm{The\:horizontal\:asymptote\:is:}$

$y=1$

Finding y-intercepts

$y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0$

$y=\left((1)/(3)\right)^0+1$

$\mathrm{Apply\:rule}\:a^0=1,\:a\ne \:0$

$\left((1)/(3)\right)^0=1$

$y=1+1$

$\mathrm{Add\:the\:numbers:}\:1+1=2$

$y=2$

$\mathrm{Y\:Intercepts}:\:\left(0,\:2\right)$

What is The approximate amount

Answers

Answer: About 80 yards

Step-by-step explanation:

From A to B =20 yards (same for E and D) right there you already have 40 yards. Every 2 units 10 yards. F to A is the same length of half of A (10 yards). If you add them all together the perimeter is about 80 yards.

Answer: 85

Step-by-step explanation:

Writing an Equation

Find the length of each side and add them up to get the total perimeter.

We know that there are 6 sides, AB, BC, CD, DE, EF, and FA

We also know that AB = ED and BC = CD = EF = FA

So the total perimeter would be AB + BC + CD + DE + EF + FA = 2AB + 4BC

Finding length of AB

This line goes from (-2,2) to (2,2) so we can find the length by subtracting the x coordinates since the y coordinates are the same

AB = 2 - (-2) = 4

Finding length of BC

Using the Pythagorean Theorem, $a^(2) +b^(2) =BC^(2)$ we can find the length of BC

This line goes from (2,2) to (3,0)

The vertical distance (a) is |0-2| = 2

The horizontal distance (b) is |3-2| = 1

So $2^(2) +1^(2) =BC^(2)$

$BC^(2) = 5$

$BC = √(5)$

Total length

Using the equation 2AB + 4BC to find the perimeter we get

$(2 * 4) + (4 * √(5) )$

= $8 +( √(16) * √(5) )$

= $8 + √(16 * 5)$

= $8 + √(80)$

Since $√(80)$ is approximately 9, we'll substitute in 9 (assuming we don't have a calculator)

≃ 8 + 9

= 17 units

Converting units

Each unit is 5 yards, so use this ratio get the perimeter in yards

17 units * 5 = 85 yards
