Answer:

15 cm is the new dimensions of new photograph

Step-by-step explanation:

initial dimension of shorter side = 8 cm

initial dimension of longer side = 10 cm

final dimension ofshorter side = 12 cm

finial dimension of longer side = x cm

The enlargement always ensure the aspect ratio

aspect ratio = lonter side/shorter side

equating, \frac{10}{8} = \frac{x}{12}

Solving for x,

10 × 12 = 8 × x

x = \frac{10 x 12 }{8} = \frac{120}{8 } = 15

        /\

        that says 10 x 12

longer side is 15cm

Answer:

Step 3 contains error.

Step-by-step explanation:

The given equation is :

\dfrac{1}{4}(\dfrac{1}{3}k+9)=6

Step 1.

Cross multiplying,

(\dfrac{1}{3}k+9)=24

Step 2.

Subtract 9 from both sides

\dfrac{1}{3}k+9-9=24-9\\\\\dfrac{1}{3}k=15

Step 3.

Cross multiplying

k=15\times 3\\\\k=45

So, there is an error in step 3. The correct answer should be 45.

John and Elijah are both driving from New York City to Richmond. John leaves
alina1380 [7]

Elijah will pass John after 5 hours, and they each will have traveled 310 miles. Then the correct option is C.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

John and Elijah are both driving from New York City to Richmond.

John leaves at 7:20 and averages 60 mph (miles per hour) on the way.

Elijah leaves at 7:30 and averages 62 mph on the way.

The situation is modeled by this system, where x is the number of hours after Elijah leaves and y is the distance each will travel.

y = 60x + 10 ...1

y = 62x        ...2

The time is taken by Elijah to cross John will be

62x = 60x + 10

 2x = 10

   x = 5 hours

The distance traveled in 5 hours will be

y = 62 (5)

y = 310 miles

Elijah will pass John after 5 hours, and they each will have traveled 310 miles.

Then the correct option is C.

More about the speed link is given below.

It takes 40 minutes for 8 people to paint 4 walls. How many minutes does it take 19people to paint 7 walls?
Slav-nsk [51]
Hey hey!


56 would be the answer.

WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.

Here’s how I got the answer:

7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.

If that helped let me know by hitting the thanks button or reply with any help you need.
