Answer:

[tex]b = l\times w[/tex] to guarantee that both formulas are the same.

Step-by-step explanation:

Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that [tex]l,w,h[/tex] have length units, whereas [tex]b[/tex] have area unit, that is, the square of length.

Hence, [tex]b = l\times w[/tex] to guarantee that both formulas are the same.

Answer:

Answer:

You need to rent

14

videos, and you'll pay the same amount for both. Renting

15

will make the membership a better method of payment.

Explanation:

We can create an equation. Say the number of videos you rent is given by

n

. We can write that, if we rent

n

videos without membership, we'll have to pay

4

n

. If we rent the same amount of videos with membership, we'll have to pay

21

+

2.5

n

.

To find the value of

n

such that the amount you pay without membership is equal to the amount you pay with, we write:

4

n

=

21

+

2.5

n

1.5

n

=

21

n

=

21

1.5

n

Answer:

18 miles

Step-by-step explanation:

Find how many miles he walked this week by multiplying 2 by 6:

2(6)

= 12

Add this to 6, since he walked 6 miles last week:

12 + 6

= 18

So, in all, he will have walked 18 miles

Answer: b =50°

Step-by-step explanation:

The angles on a straight line =180°

180° = 50°+90°+b

180°-50°-90°=b

50° = b

Answer:

Step-by-step explanation:

∠b + ∠a + 50° = 180°

∠b + ∠90 + 50° = 180°

∠b = 180° - 90° - 50° = 40°

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.

y = 2x + 4

Step-by-step explanation:

Figure out the slope.

y2 - y1 / x2 - x1       8 - 6/ 2 - 1 = 2

Find out the y-intercept. Your equation so far is y = 2x + b.

8 = 2(2) + b

8 = 4 + b

4 = b

Answer:

14 marble

Step-by-step explanation:

here's your solution

=> Total number of marble = 35

=> ratio of David and Jason = 2 : 3

=> let the ratio be in x

=> now, 2x + 3x = 35

=> 5x = 35

=> x = 35/5

=> x = 7

=> number of marble with David = 7*2 = 14

=> number of marble with Jason = 7*3 = 21

hope it helps

Answer:

number of marbles that David had=

[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]

Answer:

Jeans: 3 T-shirts: 2

Step-by-step explanation:

40 times 3 equals 120

20 times 2 equals 40

120+40=160

Joe bought 3 pairs of jeans and 2 T-shirts.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let's represent the number of pairs of jeans that Joe bought "x".

The total cost of the jeans would be $40 × x.

And the total cost of the T-shirts would be $20 × (5 - x).

Since Joe spent a total of $160, we can set up an equation to solve for x:

$40 × x + $20 × (5 - x) = $160

Expanding the second term:

$40 × x + $20 × 5 - $20 × x = $160

Combining like terms:

$40 × x + $100 - $20 × x = $160

Subtracting $100 from both sides:

$40 × x - $20 × x = $60

Combining like terms:

$20 x = $60

Dividing both sides by $20:

x = 3

So he bought 3 pairs of jeans and 5 - 3 = 2 T-shirts.
