Answer:

180

Step-by-step explanation:

Answer: width : 2.5 ft. and length : 4 ft.

Step-by-step explanation:

The area = W × L

[tex]10=W(2W-1)[/tex]

[tex]10=2W^{2} -W[/tex]

[tex]0 = 2W^{2}-W-10[/tex]

[tex]0=(2W-5)(W+2)[/tex]

W = 2.5 and -2

You can't use -2 so

[tex]L = 2(2.5)-1[/tex]

[tex]L = 4[/tex]

The daily consumption rate in the United States will be 10 barrels per person.

Your question is incomplete as you didn't provide the total barrels, therefore, an overview of the answer will be given. In their case, let's assume that the total barrels is given as 3.1 billion.

Therefore, the barrels per person will be:

= Total barrels / Population

= 3.1 billion / 310 million

= 10 barrels per person.

In conclusion, the correct option is 10 barrels per person.

The probability would be 3 out of the 10 girls

Step-by-step explanation:

The probability that a female student does not have an A on the test is 7/29.

Probability is mathematical operation that is used to determine how likely a stated event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that a female student does not have an A = number of females that do not have an A / total number of females

(29 - 20 - 2 )/ 29 = 7/29

The equation for the graph is y = [tex]2(3)^{x} -5[/tex]  .

An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.

Standard exponential equation :

y = [tex]a(b)^{x} + k[/tex]

where a is the initial value

b represents the base of the exponential function

x will represent the input of the function

y = k is the single horizontal asymptote

k is  constant

According to the question

The figure in the graph is an exponential graph .

To derive the equation

we will use Standard exponential equation :

y = [tex]a(b)^{x} + k[/tex]  

Now,

There are two points in graph

(0.-3) and (1,1)

k = - 5  ( distance from 0)

now ,

Substituting the values

y = [tex]a(b)^{x} + k[/tex]  

y = [tex]a(b)^{x} -5[/tex]

for point   (0.-3)

-3 = [tex]a(b)^{0} -5[/tex]  

-3 = [tex]a -5[/tex]

a = 2  

for point   (1,1)

1 = [tex]2(b)^{1} -5[/tex]  

1 = 2b - 5

b = 3

Therefore , equation of exponential graph is  

y = [tex]2(3)^{x} -5[/tex]  

Hence ,The equation for the graph is y = [tex]2(3)^{x} -5[/tex]  .

Answer:

  the sum of 8 terms of the series is -65104.

Step-by-step explanation:

The first term is 1.

The common ratio is (-5)/(1) = -5.

The sum of 8 terms is ...

  S8 = a1(r^8 -1)/(r -1)

  S8 = 1((-5)^8 -1)/((-5) -1) = 390624/-6 = -65104

The sum of 8 terms is -65104.

The 8th term is 1·(-5)^(8-1) = -78,125.

Answer:

Step-by-step explanation:

613 = 4x125 + 113 = 4x53 + 113

Hence the first digit (reading left to right) is a 4.

The remainder is 113 so how many 25's are there in 113?

113/25 = 4 with a remainder of 13

Thus

613 = 4x125 + 4x25 + 13 = 4x53 + 4x52 + 13

Hence the second digit (reading left to right) is also a 4.

The remainder is 13 so how many 5's are there in 13?

13/5 = 2 with a remainder of 3

Thus

613 = 4x125 + 4x25 + 2x5 + 3 = 4x53 + 4x52 + 2x5 + 3

Hence the third digit (reading left to right) is a 2 and the units digit is 3. Therefore

613 written in base 5 is 4423

Step-by-step explanation:

rectangle length is 2-3w

w=2

3 x 2=6 - 2=4

l x w

4 x 2 =8

Answer:

no solution

Step-by-step explanation:

2x + 8y = 4

x = -4y - 2

Divide both sides of the first equation by 2.

x + 4y = 2

x = -4y - 2

Substitute -4y - 2 for x in the first equation.

-4y - 2 + 4y = 2

0 - 2 = 2

0 = 4

Since after doing legal steps, we get a false statement, 0 = 4, that means there is no solution.

Answer:

Slope intercept form : y = mx + b

-4x + 2y  =  10                  Solve the equation for y

+4x        = +4x    

    2y = 4x + 10

      y = 4x/2 + 10/2           Divide all terms by 2

    multiply by -1                   Simply

[tex]\frac{1}{3} *\frac{1}{2} =\frac{1}{6}[/tex]

Step-by-step explanation:

So the first two balls are black, so the way to change the path is to take two out of six black balls over two out of ten balls, which is 1/3.

If the last one is red then the probability is that if you take one of the four red balls and you take one of the eight balls, you get 1/2.

So the total probability is 1/3 times 1/2 is 1/6.
