Answer:

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

the ratio of cats to dogs is 5 to 4 if there are a total of 63 cats and dogs how many dogs are there and how many cats ate there

Illusion [34]

Answer:

Number of cats is (5/9)(63) = 35, and number of dogs is (4/9)(63) = 28

Step-by-step explanation:

The given ratio is 5 to 4. Sum these up, obtaining 9. Then (5/9) of the whole represents the number of cats, and (4/9) of the whole represents the number of dogs.

Number of cats is (5/9)(63) = 35, and

number of dogs is (4/9)(63) = 28

As a check: 35 + 28 = 63.

Use the formula d = ( r − c ) t to find c if d = 6 , r = 4 , and t = 2 . c=

Minchanka [31]

First, we are going to want to plug in the values we are given. In this case, we will end up with the equation:

$6 = (4 - c) 2$

From here, we can solve the equation to find $c$ :

$6 = 2(4 - c)$

Apply the commutative property to rearrange the terms on the right-side of the equation to make the distributive property more apparent

$6 = 8 -2c$

Apply the distributive property

$-2 = -2c$

Subtract 8 from both sides of the equation

$1 = c$

Divide both sides of the equation by -2

We have found that c = 1.

If tan θ =(√3)/3, 0◦< θ < 360◦,

svetlana [45]

Arctan (√3 /3) = 30°. = π/6 rad

That is the value searched, in degrees and radians.

You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3

Amanda spent a total of 70 minutes competing her chores this week. Write and solve an equation to represent the number of minute

gtnhenbr [62]

Answer:

28 minutes spent in washing the dishes.

Step-by-step explanation:

Given the table

Chore time in minutes

Sweeping 42

Dishes ?

Amanda spent a total of 70 minutes competing her chores this week

Total of 70 minutes spent

42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent

let x be the number of minutes spent washing the dishes

$42+x=70$

To solve for x , subtract 42 from both sides

$42+x=70\\x= 70-42\\x=28$

28 minutes spent in washing the dishes.

A. 112 cm2 B. 64 cm2 C. 48 cm2 D. 56 cm2

goldfiish [28.3K]

The area of a triangle is taken by multiplying the length of the base times the height then dividing by 2.
l = 14cm
h = 8cm
A = $\frac{l * h}{2}$
A = $\frac{14 * 8}{2}$
A = $\frac{112}{2}$
A = 56 $cm^{2}$
