Answer: 9/10

Step-by-step explanation:

Fraction of beaded necklace made on Monday = 2/5

Fraction of beaded necklace made on Tuesday = 3/10

Fraction of beaded necklace made on Wednesday = 1/5

Total fraction made would be the addition of the Fractions made from Monday to Wednesday. This would be:

= 2/5 + 3/10 + 1/5

The lowest common multiple of the denominator is 10. Therefore we'll make them have a common denominator.

= 2/5 + 3/10 + 1/5

= 4/10 + 3/10 + 2/10

= 9/10

Answer:

13.884 grams

Step-by-step explanation:

From the question:

1 carat = 0.2 grams

The highest priced diamond = 69.42 carats.

Hence:

1 carat = 0.2 grams

69.42 carats = x grams

x grams = 69.42 × 0.2 grams

x grams = 13.884 grams

Hence, the weight of the highest priced diamonds is 13.884 grams.

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished  = 4,923.75ft²

Answer:235.5

Step-by-step explanation:

75 3/4= 75.75 (L). 81 1/4= 81.25 (W)

Perimeter= 314 3/4 of 314 is 235.5

Answer:

4

Step-by-step explanation:

31 - 6 = 25

25/4 = 5

because its LESS than that, it has to be lower than 5, therefore its 4.

Kim should be 12 years old.

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, Josh is 6 years older than 4 times Kim's age and the sum of their ages is less than 31.

From the information, let's consider Josh's age be J and that age Kim's be K

As given,

J = 6 + K ..............(i)

And,

J+K < 31

Substituting in eq(i)

6+K+K < 31

2K < 25

K < 25/2

K < 12.5

Since, Kim's age should be less than 12.5

Hence, Kim's age is 12 years.

Answer:

3y=39 :3

y=13

Step-by-step explanation:

prove me wrong

Step-by-step explanation:

the difference of 2x and 15 is less than or equal to the

sum of 4x and 17

i.e.,

2x - 15 < 4x + 17

if you want to find ahead then

2x - 15 = 4x + 17

2x - 4x = 17 + 15

- 2x = 32

x = - 32/2

x = - 2

Answer:

36

Step-by-step explanation:

Create an equation : 12 for how many pieces Stephanie took, 4 for how many children she has and 6 for how many pieces each child got:

12+ (6*4) = x

Solve:

12+24 = 36

Answer: 36 pieces

Step-by-step explanation:

We know she took 12 pieces and her four children each received 6 pieces.

12 + 4 (6) = p

12 + 24 = 36

p = 36

She started with 36 pieces.

Answer: (x, y) --> (x, -y)

Step-by-step explanation:

This is a reflection over the x-axis so its only the y-intercept that changes.

Answer:

its a reflection

Step-by-step explanation:

If it were a rotation, it wouldnt have overlapped.

If it were a translation, It would have been the wrong way up and not overlapping.

When reflected over line x, it will overlap because it stays rigid and does not change shape or size.

Step-by-step explanation:

1. 10Z–4B+3Z+16B–Z = 10Z+3Z–Z+16B–4B

= 12Z+12B = 12(Z+B)

2. –5M–3P+5P+12P = 12P+5P–3P–5M = 14P–5M

3. 12P–4M+8P–3M–2P = 12P+8P–2P–4M–3M

= 18P–7M

4. 10B–5M–4B+8B–4M = 10B+8B–4B–5M–4M

Answer:

h(n)=0−9(n−1)

Step-by-step explanation:

From the recursive formula, we can tell that the first term of the sequence is 0

and the common difference is -9

This is the explicit formula of the sequence:

h(n)=0−9(n−1)

Note that this solution strategy results in this formula, however, an equally correct solution can be written in other equivalent forms as well.

Answer:

y = 13/8

Step-by-step explanation:

Here are the steps I did:

1. y - 7/8 = 3/4 x 2/2

2. y - 7/8 + 7/8 = 6/8 + 7/8

3. y = 13/8

Answer:

Y in (-oo:+oo) Y- (7/8) = 3/4 // - 3/4. Y- (7/8)- (3/4) = 0. Y-7/8-3/4 = 0. Y-13/8 = 0 // + 13/8. Y = 13/8. Y = 13/8.

Answer:

-12

Step-by-step explanation:

Ok so I'm guessing that's a -4 but if its not, please correct me.

y= -5 is going to be plugged into 2y+2-4

This means that 2(-5)+2-4=?

2(-5) is the equivalent to 2 times -5, which is -10 (you solve multiplication first because order of operations)

Now, 2-4=-2

So using this, let's combine both equations!

-10+-2=?

?=-12

Answer:

55 degrees :)

Step-by-step explanation:

all triangles add up to 180 degrees.

we already have 70 degrees and since <S = <R they are the same # of degrees.

subtract 70 from 180 and we get 110.

divide 110 by 2=55

<S 55
