15 3/8 divided by 1/2

Answer:

If one −5s−7(8s−1): -61s+7

If two −5s−7(8s−1): -112s+14

Step-by-step explanation:

-5s-7(8s-1)

Multiply -7 onto 8s and -1:

-5s-56s+7

add -5s and -56s:

-61s+7

−5s−7(8s−1)−5s−7(8s−1)

Multiply both -7 to 8s and -1

-5s-56s+7-5s-56s+7

add:

-112s+14

Given:

10:s

6:y

8:13

Solve:

8/13 = 10/s

s = 65/4 or 16.25 cm

8/13 = 6/y

y = 39/4 or 9.75 cm

5.

Given:

70ft:88ft

o/90ft

n/53ft

Solve:

70/88 = o/90

o = 1575/22 or 71.59 ft

70/88 = n/53

n = 1855/44 or 42.16 ft

6.

Given:

5.7in:9.1in

9.6in:e

11.2in:t

Solve:

5.7/9.1 = 9.6/e

e = 15.33 in

5.7/9.1 = 11.2/t

t = 17.88 in

7.

Given:

74m:48m

43m:u

64m:y

Solve:

74/48 = 43/u

u = 1032/37 or 27.89 m

74/48 = 64/y

y = 1536/37 or 41.51 m

8.

Given:

16cm:o

11.8cm:101 (I can't see if that is a 101 or 10.1 but I can do it both ways)

6.2cm:t

Solve:

11.8cm/101 = 16cm/o

o = 136.95

or

11.8cm/10.1 = 16cm/o

o = 13.69

11.8cm/101 = 6.2cm/t

t = 53.07

or

11.8cm/10.1 = 6.2cm/t

t = 5.3

9.

Given:

AB:AC

AE:AD

EB:DC

ABE:ACD are right angles

DC = P

We know that:

13ft:30ft

AE:AD are unknown

8ft:DC

We are looking for P?

Solve:

13ft/30ft = 8ft/P

P = 240/13 or 18.46

The fractional equivalent of the repeating decimal 0.5 is 5/9.

To convert the repeating decimal into a fraction, we can assign a variable, let's say x, to the repeating decimal. In this case, x = 0.5555...

Next, we multiply both sides of the equation by a power of 10 that will eliminate the repeating part.

10x = 5.5555...

Now,we subtract the original equation from the new equation to eliminate the repeating part:

10x - x = 5.5555... - 0.5555...

9x = 5

Simplifying the equation, we get:

x = 5/9

Therefore, the correct answer is A. 5/9.

Answer:

Y=21

X=8

Step-by-step explanation:

In the middle there is a right angle

therefore 27 +3y=90

Y will be 21

Then x+27+63+8x+18=180

x=8

Hence 8+27+3(21)+8(8)+18=180

Step-by-step explanation:

27 + 3y = 90

3y = 90 - 27

y = 21

27 + (21×3) + x + 8x + 18 = 180 ( angles on a straight line sum up to 180)

9x + 108 = 180

9x = 180 - 108

9x = 72

x = 72/9

x = 8 degrees

Answer:

I think you need to know the value of X to get this answer.

Greatest Common Factor: 24

Step-by-step explanation:

The greatest common factor is found by multiplying all the factors which appear in both lists: So the GCF of 24 (2x2x2x3) and 48 (2x2x2x2x3) is 2x2x2x3 which is 24.

The greatest common factor of 24 and 48 is 24.

Here, we have,

To find the greatest common factor (GCF) of 24 and 48,

we can use the prime factorization method:

Step 1: Find the prime factorization of each number.

Prime factorization of 24:

24 = 2 * 2 * 2 * 3

Prime factorization of 48:

48 = 2 * 2 * 2 * 2 * 3

Step 2: Identify the common prime factors and their lowest exponents.

Common prime factors: 2 * 2 * 2 * 3

Step 3: Multiply the common prime factors with their lowest exponents.

GCF(24, 48) = 2 * 2 * 2 * 3 = 24

So, the greatest common factor of 24 and 48 is 24.

Finding the width:

In the image, we notice a right-angle triangle

So, we can find x using the Pythagoras theorem

Using the Pythagoras theorem:

18² = 7² + x²

x² = 18² - 7²

x² = 324 - 49

x² = 275

x = 16.6

Hence, the screen is 16.6 inches wide

We are to find the width of the laptop

The width of the laptop is 16.6 inches

Diagonal length of the laptop = 18 inches

Length of the laptop = 7 inches

Width of the laptop = x inches

Using Pythagoras theorem

Diagonal ² = length ² + width ²

18² = 7² + x²

x² = 18² - 7²

x² = 324 - 49

x² = 275

find the square root of both sides

x = √275

x = 16.58

Approximately,

x = 16.6 inches
