Rock ran 3/4 of an hour on Wednesday for a distance of 4.2 miles.On Thursday, he ran for 1 hour at the same speed he ran on Wednesday.How many miles did Rick run on Thursday

Answers

Answer 1

Answer:

the number of miles run on Thursday is 5.60 miles

Step-by-step explanation:

The computation of the number of miles run on Thursday is shown below

Here we assume the number of miles be x

3 ÷ 4 ÷ 1 = 4.2 ÷ x

3 ÷ 4 ÷ x = 4.2

3x = 16.8

x = 5.6

Hence, the number of miles run on Thursday is 5.60 miles

What is the value of x

Answers

Answer:

13

Step-by-step explanation:

We now that the two angles are equal due to them being vertical angles. This way, we can safely set them equal to each other.

4x - 14 = 58

To find what x equals, we first need to get x by itself. That means now we have to add 14 on both sides, leaving us with:

4x = 72

Now we divide 4 on both sides:

x = 13

Which ordered pair is the best estimate for the solution of the system of equations?


y=−34x−2y=x+6




a (−4.5,1.75)


b(−4.25,1.5)

c(−4.5,1.5)

d(−4.75,1.75)

Answers

Use the second equation. Replace x with the answer choices and if it equals the y value than that is the answer:

Y = x + 6

-4.5 + 6 = 1.5

The answer would be C. (-4.5,1.5)

Answer:

c(−4.5,1.5) is your answer

Step-by-step explanation:

because 4 × 11 is 44 and all the sides are equal

Answer:

44inches

Step-by-step explanation:

Since all of the sides are equal, you just need to multiply 11 with 4.

11x4=44

or

there are 4 sides and each side equals 11 so-

11+11+11+11=44

Answers

There are four rectangles and 2 squares.

Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________

Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2

TOTAL: 392+392 = 784 cm^2

Wow I should have realized the the 4 rectangles are the area as the two squares.

Good luck to you!
