Emilia and Rose ran around a track. Emilia ran 3 more laps than Rose. Altogether, they ran 11 laps.

Miss Lianto mowed 2/7 of her lawn. Her son mowed 1/4 of it. Who mowed most of the lawn? How much of the lawn still needs to be m

Nuetrik [128]

Answer: 2/7 = 8/28

1/4 = 7/28

Therefore Mr Pham mowed more.

8+7 = 15 so 15/28 of lawn has been mowed, therefore 13/28 of the lawn is left still to be mowed.

Mr. Pham mowed more of the lawn than his son.

it still needs ¹³/₂₈ of the lawn to be mowed.

A. Name the smallest angle and the largest angle of the following triangles: F 6 S 5 1. A J 5.03 7 5 G B H 5.1 2. D 4 3 E

I am Lyosha [343]

Answer:

(smallest, largest) = (B, C), (D, E), (G, J)

Step-by-step explanation:

Side lengths of a triangle are proportional to the sine of the opposite angle. In a triangle, a larger angle will always have a larger sine. That means the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side.

__

The shortest side is 5 units, opposite angle B. The longest side is 7 units, opposite angle C.

smallest angle: B
largest angle: C

The shortest side is 3 units, opposite angle D. The longest side is 5 units, opposite angle E.

smallest angle: D
largest angle: E

The shortest side is 5 units, opposite angle G. The longest side is 5.1 units, opposite angle J.

smallest angle: G
largest angle: J

_____

<em>Additional comment</em>

Angles in a triangle may exceed 90°. The sine function actually is decreasing for angles above 90°. However, since the total of angles of a triangle must be exactly 180°, there <em>cannot be two angles in a triangle such that the smaller angle has the larger sine</em>.

Which equation is related to the given equation? column a column b 1. 61 + 18 = z 2. z = 61 – 18 3. –18 = 61 – z 4. 18 = 61 – z

Fofino [41]

Question 1.).

Column A.):

Answer ==> z = 61 – 18, is Related to z + 18 = 61, ==> z = 43

Answer: ===> 18 = 61 - z, is Related to z + 18 = 61, ===> z = 43

z + 18 = 61

Let's solve your equation step-by-step.

z + 18 = 61

Step 1: Subtract 18 from both sides.

z + 18 − 18 = 61 − 18

z = 43

Graph: ========> z + 18 = 61 =========> z =======> 43

Column (A), Answer: =======> z = 43

Question 2.).

Column. B.):

Answer: =====> 61 + 18 = z, Related to z - 18 = 61 ====> z = 79 Answer: ===> –18 = 61 – z, Related to z - 18 = 61 ====> z = 79

z - 18 = 61

Let's solve your equation step-by-step.

z − 18 = 61

Step 1: Add 18 to both sides.

z − 18 + 18 = 61 + 18

z = 79

Answer z = 79

Therefore, The answers to your Equation: Column (A),/Column (B)

Question 1.).

Column A.):

Answer ==> z = 61 – 18, is Related to z + 18 = 61, ==> z = 43

Answer: ===> 18 = 61 - z, is Related to z + 18 = 61, ===> z = 43

Question 2.).

Column. B.):

Answer: =====> 61 + 18 = z, Related to z - 18 = 61 ====> z = 79 Answer: ===> –18 = 61 – z, Related to z - 18 = 61 ====> z = 79
