Answer:

8

Step-by-step explanation:

yellow marbles=2b-7

blue marbles=2b

2b+2b-7=23

4b=23+7

4b=30

b=30/4

b=7.5

yellow marbles=2b- 7

2 x 7.5 -7

15 - 7

=8

Answer:

The value of x is 4

Step-by-step explanation:

Mathematically, we can calculate the area of the quilt by having the product of the side of the quilt by itself

Mathematically, the area of the quilt = L^2

This is (x + 2) * (x + 2)

This product is equal to 36 feet square

Thus;

(x + 2)^2 = 36

(x + 2)^2 = 6^2

Since the powers are equal, we equate the bases

x + 2 = 6

x = 6-2

x = 4

Answer:

Nestor needs to buy 7 ½ meters rope

And: the length of the rope that is greater is : 9 meters

Step-by-step explanation:

From the length conversion table:

We know that:

1 meters = 100 centimetres

We are told that Nestor needs 750 centimeters of rope

Now; these ropes comes in the length of 4 ½ meters and 9 meters at the hardware store

To determine the  length of rope should Nestor buy? ; we will need to first convert the length of the ropes in meters to centimeters first;

so

4 ½ meters to centimeters = 4 ½ × 100 centimeters = 450 centimeters

9 meters to centimeters = 9 × 100 centimeters = 900 centimeters

And Nestor needs to purchase 750 centimeters of rope;

So if ;

4 ½ meters = 450 centimeters

Then ; let x meters = 750 centimeters

So;

x meters × 450 centimeters = 4 ½ meters × 750 centimeters

x meters = (4 ½ meters × 750 centimeters) / 450 centimeters

x = 7 ½ meters

Also;  if

9 meters  =  900 centimeters

Then ; let x meters = 750 centimeters

So;

x meters × 900 centimeters = 9 meters × 750 centimeters

x meters = (9 meters × 750 centimeters) / 900 centimeters

x = 7 ½ meters

Thus; Nestor needs to buy 7 ½ meters rope

And: the length of the rope that is greater is : 9 meters

Answer:

Nestor should buy the rope that is 9 meters long

Step-by-step explanation:

Nestor will need to buy a rope that is longer than 750 centimeters so that he can easily cut it to serve his need. If he buys a shorter rope, it will be a  lot more difficult to join to get the required length that he needs.

To know the length of his various options and determine the one that is best, we will convert all the ropes to the same unit (cm) and compare is with the required length.

Rope A:  4.5 meters

1 m = 100 cm

4. 5 cm = 4.5 X 100 = 450 cm

This is clearly shorter than is required

Rope B:  9 meters

1 m = 100 cm

9 m = 9 X 100 =  900 cm

This is clearly longer than is required, hence should be Nestor's choice

Answer:

j+47=55

Step-by-step explanation:

“the sum of” means adding, so you add j and 47, which is or is equal to 55

j+47=55

w = 3(2a + b) - 4

First, add 4 to both sides:

w (+4) = 3(2a + b) - 4 (+4)

w + 4 = 3(2a + b)

Next, divide 3 from both sides:

(w + 4)/3 = (3(2a + b))/3

(w + 4)/3 = 2a + b

Next, subtract b from both sides:

((w + 4)/3) - b = 2a + b (-b)

(w + 4)/3 - b = 2a

Finally, divide 2 from both sides:

((w + 4)/3 - b)/2 = (2a)/2

a = (((w + 4)/3) - b)/2

a = (((w + 4)/3) - b)/2 is your answer.

Answer:

[tex]\frac{w}{6} +\frac{2}{3} -\frac{3b}{6}[/tex]=a

Step-by-step explanation:

w=3(2a+b)-4 ---> add 4 to both sides

w+4=3(2a+b) --> distribute the 3

w+4= 6a+3b--> subtract 3b from both sides

w+4-3b=6a ---> to isolate the a divide both sides by 6

[tex]\frac{w}{6} +\frac{2}{3} -\frac{3b}{6}[/tex]= a ---> I hope this was what you were looking for

Answer:

The correct option is B,15% tax rate with $375 in taxes owed

Step-by-step explanation:

Mary has a taxable income of $40,000 which implies that Mary falls into tax bracket of capital gains tax of 15% for taxable income between $38,601 and $425,800.

The amount capital gains tax payable is however the capital gains itself multiplied by the percentage applicable of 15% not the entire taxable income since that consisted of other income from other sources aside from capital gains

capital gains tax=$2500*15%=$375

Answer: Its C, the rationale is that short-term capital gains are taxed at income tax rate

Step-by-step explanation:

$2500=$550  22%

Answer:

(B) -8

Step-by-step explanation:

Given the 2-column table below:

[tex]\left|\begin{array}{c|c}x&y\\--&--\\-3&14\\-1&10\\1&6\\4&0\\8&?\\10&-12\end{array}\right|[/tex]

Taking the pair (-3,14) and (-1,10)

[tex]Slope, m=\dfrac{10-14}{-1-(-3)} =\dfrac{-4}{2} =-2[/tex]

Taking the pair (1,6) and (4,0)

Slope, [tex]m=\dfrac{0-6}{4-1} =\dfrac{-6}{3} =-2[/tex]

Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:

Taking the pair (8,y) and (4,0)

Slope, [tex]m=\dfrac{0-y}{4-8} =-2[/tex]

[tex]\dfrac{-y}{-4} =-2\\y=-2*4=-8[/tex]

Therefore, the value of ? on the y-column is -8.

Answer:

15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 26, \sigma = 3[/tex]

Approximately what percentage of her shots will travel less than 23 feet?

This is the pvalue of Z when X = 23. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{23 - 26}{3}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a pvalue of 0.1587.

15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.

Answer:

0.4231 or 42.31%

Step-by-step explanation:

In a standard 52 card deck there are 13 spade cards (52/4) and there are 12 face cards (4 suits x 3 face cards). Moreover, 3 cards are both face and spade cards.

Therefore, the probability that the card Bashir chooses is either a face card or a spade is given by:

[tex]P(F\ or\ S)=P(F)+P(S)-P(F\ and\ S)\\P(F\ or\ S)=\frac{13}{52} +\frac{12}{52} -\frac{3}{52}\\P(F\ or\ S)=0.4231[/tex]

The probability is 0.4231 or 42.31%

Answer: y=-2x + 3

Step-by-step explanation:

(0,3)   and (2,-1)

3-(-1)= 4

0-2= -2  

4/-2= -2  so the slope is -2  and we already know the y intercept is 3 because that is when x is 0.

so the equation will    y= -2x + 3
