Answer:

20 ÷ [tex]\frac{5}{3}[/tex] = 12

Step-by-step explanation:

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

20 x 3 divided by 5 = 60\5

Thus, the answer to 20 divided by 5/3 in fraction form is:

[tex]\frac{60}{5} = 12[/tex]

Answer:

16ft

Step-by-step explanation:

The answer is 16ft because the area of a trapezoid is a + b/2  x h.

5 + 8/2 = 13/2 = 6.5

104/6.5 = 16

The height is 16ft.

  (c)  All of the triangles are similar

Step-by-step explanation:

All of the triangles are similar by the AA similarity postulate.

__

Two angles of one triangle being the same as two angles of another triangle means all angles of the two triangles are the same. (Two angles define the third.) Triangles with congruent corresponding angles are similar.

Answer:

k=11.111111111111, D=2600/39, A=16.81, C=400, W=27.75, K=10

Step-by-step explanation:

Hope this helped!

If A = 52 and K=22 then D = 63.44 and if Given A = 361 and K = 5 then

C = 398.0025.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A = 52 and k = 22.

From the diagram, D is (100 + 22)% = 122% of A.

Therefore,

D = (122/100)×52.

D = 63.44.

Given, A = 361 and k = 5.

Therefore,

C = (105/100)×361

C = 379.05 and again 105% of 379.05.

C = (105/100)×379.05.

C = 398.0025

Answer:

Step-by-step explanation:

#1.

2x² + 24x + 10 = 0

2(x² + 12x + 5) = 0

2[ x² + 2(6)x + 6² - 6² + 5 ] = 0

2[(x + 6)² - 31] = 0

2( x + 6 - √31 )( x + 6 + √31 ) = 0

[tex]x_{1}[/tex] = - 6 + √31

[tex]x_{2}[/tex] = - 6 - √31

#2.

f(x) = 3x² - 36x - 12

f(x) = 3( x² - 12x - 4 )

f(x) = 3 [ x² - 2(6)x + 6² - 6² - 4 ]

f(x) = 3 [( x - 6 )² - 40 ]

f(x) = 3( x - 6 )² - 120

The expression 5(4) - 6 + 5(4) - 6 is equivalent to (k + k)(4) option fourth is correct.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is:

If k(x) = 5x – 6, which expression is equivalent to (k + k)(4)?

Plug k = 4 in the function:

k(4) = 5(4) - 6

Now,

= (k + k)(4)  or

= k(4) + k(4)

= 5(4) - 6 + 5(4) - 6

Thus, the expression 5(4) - 6 + 5(4) - 6 is equivalent to (k + k)(4) option fourth is correct.

32 muffins that carlos sells - 25 = 7 muffins

Answer:

7

Step-by-step explanation:

Fewer in this question = Subtract

32-25=7

Hence, Carlos sell 7 fewer muffins.

[RevyBreeze]

5x + 25 + x + 5 = 90

6x + 30 = 90

6x = 90 - 30

6x = 60

x = 10

Solution:

We can see that the 90° angle is divided into two angles. Thus, the sum of two angles must equal 90°.

Combine like terms:

Subtract 30 both sides:

Divide 6 both sides:

The value of x is 10.

C (-5,[tex]\frac{8}{3}[/tex])

Step-by-step explanation:

I uses demos graphing calculator

First, found the slope using point (0,6) and (3,8)

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{8-6}{3-0}[/tex]

m = [tex]\frac{2}{3}[/tex]

m = slope

Now I will be able to form a linear equation:

y = mx + b (is our y-intercept, when x is 0) When x is 0, y is 6 (0,6)

y = [tex]\frac{2}{3}[/tex]x + 6

I graphed that on demos, and that's how I got my final answer.

I would attach the link to the graph, but brainly deleted my answer before. So, try to write that in to demos (y = [tex]\frac{2}{3}[/tex]x + 6) if you want to see the graph.

From the kite ABCD, ∠ABD = 65° and ∠CBD = 46°

∠ABC≅∠ADC

∠EDC = 180 - 90 - 44 (sum of angle in a triangle)

∠EDC = 46°

∠EDC ≅∠EBC

∠ADE = 180 - 25 - 90  (sum of angle in a triangle)

∠ADE = 65°

∠ADE ≅ ∠ABD(Base angle of isosceles triangle)
