Answer:

Step-by-step explanation:

(33−7)(5)/10+1+3+6+9−10

= (27−7)(5)/10+1+3+6+9−10

= (20)(5)/10+1+3+6+9−10

= 100/10+1+3+6+9−10

=10+1+3+6+9−10

=10+4+6+9−10

=10+10+9−10

=10+19−10

=10+9

=19

Mina says triangle A with angles

kotykmax [81]

Answer:

Yes, Mina is correct

Step-by-step explanation:

Let the triangles be A and B

Given

Triangle A:

$Angles = 34, 57$

Triangle B:

$Angles = 89, 57$

Required

Is Mina's claim correct?

First, we calculate the third angle in both triangles.

For A:

$Third\ Angle = 180 - 34 - 57$

$Third\ Angle = 89$

For B:

$Third\ Angle = 180- 89 - 57$

$Third\ Angle = 34$

For triangle A, the angles are: 34, 57 and 89

For triangle B, the angles are: 34, 57 and 89

<em>Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.</em>

Aubrey used 4/7 liters of paint for a mural in her room and 2/10 liter for a wall in her bathroom. Determine a reasonable estima

NemiM [27]

Answer:

27/35 is the exact answer

7/10 is an estimate

Step-by-step explanation:

4/7+2/10

Simplify the fraction

4/7+1/5

The common denominator is 35

4/7*5/5 + 1/5 *7/7

20/35 + 7/35

27/35

To estimate

4/7 is close to 1/2

2/10 is close is 1/5

1/2 + 1/5 =

5/10 + 2/10 = 7/10

Tres hermanos van a repartirse un pastel y medio, cuanto le toco de pastel a cada uno de los hermnos

Anna71 [15]

Answer:

medio pastel cada uno

Step-by-step explanation:

Hay 3 hermanos, si decimos que un pastel entero tiene 6 pedazos entonces su fraccion seria 6/6. Si dividimos este pastel entre los tres hermanos cada uno tendria...

$\frac{6 / 3}{6}$ = $\frac{2}{6}$

Medio pastel seria la mitad de 6/6 que seria 3/6. Si dividimos esto entre los 3 hermanos cada uno tendria...

$\frac{3 / 3}{6} = \frac{1}{6}$

Ahora que dividimos los 2 pasteles tenemos que unir las fracciones para saber cuanto pastel le toco a cada hermano...

$\frac{2}{6} + \frac{1}{6} = \frac{3}{6}$ o medio pastel cada uno

My brain stopped. Please help

Over [174]

Answer:

∠1 = 90°

∠2 = 66°

∠3 = 24°

∠4 = 24°

Step-by-step explanation:

Usually the diagonals of a rhombus bisect each other at right angles.

Thus; ∠1 = 90°

Since they bisect at right angles, then;

∠R1S = 90°

Now, sum of angles in a triangle is 180°

Thus;

66° + 90° + ∠4 = 180°

156 + ∠4 = 180

∠4 = 180 - 156

∠4 = 24°

Now, also in rhombus, diagonals bisect opposite angles.

Thus; ∠4 = ∠3

Thus, ∠3 = 24°

Similarly, the diagonal from R to T bisects both angles into 2 equal parts.

Thus; ∠2 = 66°
