Landen spent L hours at the beach last weekend. Matéo spent 15% fewer hours at the beach than Landen did.

Mathematics

Answer:

L(1-0.15)

L-(15/100)L

Step-by-step explanation:

we  know that

100%-15%=85%

85%=85/100=0.85

so

The number of hours that Mateo spent at the beach last week is equal to the hours that landen spent at the beach (L) multiplied by 0.85

The linear equation that represent this situation is

0.85L  

<u><em>Equivalent expressions are</em></u>

1) L(1-0.15)

Because

Applying distributive property

L(1-0.15)=L-0.15L

Combine like terms

L-0.15L=0.85L

2) L-(15/100)L

because

15/100=0.15

substitute

L-(15/100)L=L-(0.15)L=0.85L

Answer:

to find midpoint add both"X" coordinates and divide by 2

also add "Y" coordinates and divide by 2

then for line of segment use distance formula which is D=√[(x2-x1)²+(y2-y1)²]

Brinn's rectangular kitchen has an area of 81 square feet. The kitchen is 9 times as many square feet as Brinn's pantry. If the

The length of the pantry is 3 feet. this is because if the pantry is 9 times smaller than the kitchen, the area of the pantry must be 9 feet. Therefore, if the width of the pantry is 3 feet, the length of the pantry must be 3 feet.

A 4-foot tall child walks directly away from a 12-foot tall lamppost at 2 mph. How quickly is the length of her shadow increasin
xz_007 [3.2K]

Answer:

The length of the shadow is increasing with the rate of 1.5 feet per sec

Step-by-step explanation:

Let AB and CD represents the height of the lamppost and child respectively ( shown below )

Also, let E be a point represents the position of child.

In triangles ABE and CDE,

\angle ABE\cong \angle CDE    ( right angles )

\angle AEB\cong \angle CED  ( common angles )

By AA similarity postulate,

\triangle ABE\sim \triangle CDE

∵ Corresponding sides of similar triangles are in same proportion,

\implies \frac{AB}{CD}=\frac{BE}{DE}

We have, AB = 12 ft, CD = 4 ft, BE = BD + DE = 6 + DE,

\implies \frac{12}{4}=\frac{6+DE}{DE}

12DE = 24 + 4DE

8DE = 24

DE=3

Now, the speed of walking = 2 mph = \frac{2\times 5280}{3600}\approx 2.933\text{ ft per sec}

Note: 1 mile = 5280 ft, 1 hour = 3600 sec

Thus, the time taken by child to reach at E  

= \frac{\text{Walked distance}}{\text{Walking speed}}

=\frac{6}{2.933}

= 2.045 hours

Hence, the change rate in the length of shadow

= \frac{\text{Length of shadow}}{\text{Time taken}}

=\frac{3}{2.045}

= 1.5 ft per sec.
