Answer:

8.25 or 8 1/4

Step-by-step explanation:

4 1/8 converted to a decimal is 4.125, multiply that by 2 and you get 8.250 (take the zero off, because you don't need it) and if you need you can convert 8.25 back to a fraction, which is 8 1/4. Hope this helps! ;)

Answer:

210 units squared

Step-by-step explanation:

V = l × w × h

V = 3 × 7 × 10

V = 210 units squared

The sum of the first 75 terms of the sequence is -5.068*10^34

Given the following geometric sequence

[tex]a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)[/tex]

The sum of the nth term of the GP is expressed as;

[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]

a = -1/3

n = 75

r = a₂/a₁

a₂ = -3a₁

a₂ = -3(-1/3)

a2 = 1

r = 1/(-1/3)

r = -3

Substitute the given values in the formula;

[tex]S_n = \frac{-1/3(1-3^{75})}{1-(-3)}\\S_{75} = \frac{-1/3(3^{75}-1)}{1+3} \\S_{75} = \frac{-1/3(6.082 \times 10^{35}-1)}{4}\\S_{75} = \frac{-1/3(6.082 \times 10^{35})}{4}\\S_{75} = -0.5068 \times 10^{35}\\S_{75} = -5.068 \times 10^{34}\\[/tex]

Hence the sum of the first 75 terms is -5.068*10^34

Answer:

The answer is 55 degrees.

Step-by-step explanation:

As shown by the red box on the angle, the angle shown is a right angle and is 90 degrees. Because we know the total angle measure, we can subtract the 31 degree angle from the 90 degree angle, which leaves us with 59 degrees for the second angle. This second angle equals (x+4). We then solve for x by setting up the equation 59= x+4. Subtract 4 from both sides and you are left with 55 degrees for x.

i think its B) because its a subtraction equation

The equation that represents the total number of canned goods in Homeroom 106 on Monday will be 64 - c = 17. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

On Monday, Homeroom 104 turned in 64 canned goods. This is 17 less than the number of canned goods Homeroom 106 turned in.

Let c be the total number of canned goods in Homeroom 106. Then the equation is written as,

64 - c = 17

The equation that represents the total number of canned goods in Homeroom 106 on Monday will be 64 - c = 17. Then the correct option is B.

Answer:

The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].

Step-by-step explanation:

The exponential model can be modelled by the following mathematical expression:

[tex]y = A\cdot e^{B\cdot x}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]A, B[/tex] - Coefficients.

If we know that [tex](x_{1}, y_{1}) = (7,12)[/tex] and [tex](x_{2}, y_{2}) = (8,25)[/tex], then we get the following system of equations:

[tex]A\cdot e^{7\cdot B} = 12[/tex] (2)

[tex]A\cdot e^{8\cdot B} = 25[/tex] (3)

If we divide (3) by (2), we calculate the value of [tex]B[/tex]:

[tex]e^{B}=\frac{25}{12}[/tex]

[tex]B = \ln \frac{25}{12}[/tex]

[tex]B \approx 0.734[/tex]

And by (2), we determine the value of [tex]A[/tex]:

[tex]A = 12\cdot e^{-7\cdot B}[/tex]

[tex]A = 0.0704[/tex]

The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].

Answer:

The probability of not selecting a red marble, P(R)'  = 10/19

Step-by-step explanation:

The probability of an event occurring is equal to the number of ways the required event occurs divided by the number of possible outcomes

The number of ways of an event not occurring is 1 less the probability of the event occurring

The number of green marbles in the bag = 6

The number of red marbles in the bag = 9

The number of blue marbles in the bag = 4

The sum of the marbles in the bag, n = 6 + 9 + 4 = 19

The number of ways of selecting a red marble = 9 ways

The probability of selecting a red marble = 9 ways/19 marbles = 9/19

The probability of not selecting a red marble = 1 - 9/19 = 10/19 = [tex]0.\overline{526315789473684210}[/tex]

The probability of not selecting a red marble P(R)' = 10/19

Answer:

The probability of NOT selecting a red marble is 10/19 (or 52.6%)

Step-by-step explanation:

6 green+ 9 red+ 4 blue = 19 marbles in total. So 19 would be our denominator. The total of marbles that IS NOT red is 10 total (6+4). Now we would put 10 as our numerator. 10/19. We could simplify but 10 and 19 have no common factors. So it would but stay 10/19. Hope this helped
