Step-by-step explanation:

Jack mows 1 lawn in 3 hours

= 1/3 lawn in 1 hour

Marilyn mows 1 lawn in 6 hours

= 1/6 lawn in 1 hour

Together, they can mow 1/3 + 1/6

= 1/2 lawn in 1 hour.

Hence they will need 2 hours to mow the lawn.

In XYZ, mX=90 and mY=30.In TUV,mU= 30 and mV=60. Which is true about the two triangles? XYZ=TUV, XYZ= VUT,No congruency statemen
Flauer [41]

Answer:

No congruency statement can be made because the side length are unknown.

Step-by-step explanation:

The sum of the measures of all interior angles in a triangle is always 180°.

In triangle XYZ,

m\angle X=90^{\circ}\\ \\m\angle Y=30^{\circ},

then

m\angle X+m\angle Y+m\angle Z=180^{\circ}\Rightarrow m\angle Z=180^{\circ}-90^{\circ}-30^{\circ}=60^{\circ}

In triangle TUV,

m\angle U=30^{\circ}\\\\m\angle V=60^{\circ},

then

m\angle T+m\angle U+m\angle V=180^{\circ}\Rightarrow m\angle T=180^{\circ}-30^{\circ}-60^{\circ}=90^{\circ}

We have two triangles with congruent angles but we have no information about side lengths. Therefore, can not be made because the side length are unknown. Correct option is last option.

Crickets can jump with a vertical velocity of up to 14 ft/s. Which equation models the height of such a jump, in feet, after t s
Natasha_Volkova [10]
Acceleration is simplified by assuming it is the constant -g

a=-g  we integrate this with respect to time to get v...

v=-gt+C  where C is the initial velocity in this case 14ft/s so

v=-gt+14  integrate again to get the height function

h=(-gt^2)/2 +14t +C  we are not given an initial height so C is 0

h(t)=14t-gt^2/2   letting g=32 and neatening up a bit...

h(t)=14t-16t^2
