The length of toy jeep = [tex]12 \frac{1}{2}[/tex]

= [tex]\frac{25}{2}[/tex] inches

The length of actual Jeep = [tex]18 \frac{3}{4}[/tex] feet

We have to find the ratio length of a toy jeep to the length of actual jeep.

Firstly, we will make the dimensions of the both the given lengths same.

As 1 foot = 12 inches

[tex]18 \frac{3}{4}[/tex] feet = [tex]18 \frac{3}{4} \times 12[/tex] inches

=[tex]\frac{75 \times 12}{4}[/tex]

= 225 inches

So, the ratio length of toy jeep to actual jeep

= [tex]\frac{25}{2} \div 225[/tex]

= [tex]\frac{25}{2} \times \frac{1}{225}[/tex]

= [tex]\frac{1}{18}[/tex]

= 1:18

So, the ratio length of a toy Jeep to the length of a actual Jeep is 1:18.

Length of toy jeep = [tex]12\frac{1}{2}=\frac{25}{2}[/tex] inches

Length of actual jeep = [tex]18\frac{3}{4}=\frac{75}{4}[/tex] feet

Now to find the ratio between the two, we must convert both of them in same units. So, lets convert the actual jeep length in feet to inches.

1 feet = 12 inches.

So, [tex]\frac{75}{4}[/tex] feet = [tex]\frac{75}{4}\times12=225[/tex] inches

Ratio of length of toy jeep to actual jeep will be =

[tex]\frac{\frac{25}{2}}{225}[/tex]

[tex]\frac{25}{2\times225}[/tex]

[tex]\frac{25}{450}[/tex] = [tex]\frac{5}{90}[/tex]

ratio is : [tex]\frac{1}{18}[/tex] or 1:18

Answer:

Remainder is 36.

Step-by-step explanation:

We are given that f(x) is divided by x+3 using synthetic division, and  we are given with table attached in the image.

In synthetic division, first row represents the coefficients of dividend. From the given table, dividend is f(x)=[tex]2x^{2}-5x+3[/tex] and  since f(x) is divided by x+3, divisor is -3.

First two numbers of last row represents coefficients of quotient and last most number of third row is remainder.

And we can write f(x) as (x+3)(2x-11)+36.

Hence remainder is 36 , when f(x) is divided by x+3.

Answer:

36

Step-by-step explanation:

this i believe is the settup u were describing

x = 0

distribute parenthesis on both sides of the equation and simplify

3x - 7 - 4x = 10x - 8 + 1

- x - 7 = 10x - 7 ( subtract 10x from both sides )

- 11x - 7 = - 7 ( add 7 to both sides )

- 11x = 0 ( divide both sides by - 11 )

x = 0

f(x) = 8000 - (8000)(0.11)x

Answer:

The answer is option (C), One cement bridge post weighs 9,135 pounds

Step-by-step explanation:

Step 1: Get the total volume of a cement bridge post

The cement bridge post is in the shape of a cuboid, therefor the volume of the cement bridge post can be expressed as;

Volume of cement bridge post=Base area×Length

where;

Base area=(24^2) inches square

1 foot=12 inches

Convert 24 inches to foot=24/12=2^2=4 feet²

Length=15 feet and 9 inches

1 foot=12 inches

Convert 9 inches to foot=9/12=0.75 feet

Total length=(15+0.75)=15.75 feet

replacing;

Volume of cement bridge post=(4×15.75)=63 cubic feet

Volume of cement bridge post=63 cubic feet

Step 2: Get the total weight of the cement bridge post

Total weight of the cement bridge post=Weight per cubic foot×total volume of the cement bridge post

where;

Weight per cubic foot=145 pounds per cubic foot

Total volume of the cement bridge post=63 cubic feet

replacing;

Total weight of the cement bridge post=(145×63)=9,135 pounds

One cement bridge post weighs 9,135 pounds

For this case we have:

The equation in vertex form of the parabola is given by:

[tex]y = a (x-h) ^ 2 + k\\[/tex]

The vertex is (h, k) and is given by the highest or lowest point of the parabola, in this case it is observed that it is [tex](h, k) = (- 3, -1)\\[/tex]

Thus, the equation is given by:

[tex]y = a (x - (- 3)) ^ 2 + (- 1)\\\\y = a (x + 3) ^ 2-1\\[/tex]

We look for the value of a, substituting a point of the parabola in the equation in the form of vertex, we will take the point [tex](x, y) = (0,8)\\[/tex]

Substituting we have:

[tex]8 = a (0 - (- 3)) ^ 2 + (- 1)\\\\8 = a (0 + 3) ^ 2-1\\\\8 = a (3) ^ 2-1\\[/tex]

[tex]8 = 9a-1\\\\8 + 1 = 9a\\\\9 = 9a\\[/tex]

[tex]a = \frac{9}{9}\\\\a = 1\\[/tex]

First, we find the total number of marbles.

We add up the red, blue, and yellow marbles:

The number of red marbles is 7 + 4 which equals to 11.

The number of blue marbles is 5.

The number of yellow marbles is 2.

To find the total number, we add these numbers together: 11 (red) + 5 (blue) + 2 (yellow) = 18. So, the total number of marbles is 18.

Second, we find the probability of each event - that is, picking a red marble and then a yellow marble.

Probability is the number of desired outcomes divided by the total number of possible outcomes.

The probability of picking a red marble, denoted as P(red) is the number of red marbles divided by the total number of marbles. So, P(red) = 11 / 18 which is about 0.611 or 61.1%.

The probability of picking a yellow marble, denoted as P(yellow) is the number of yellow marbles divided by the total number of marbles. So, P(yellow) = 2 / 18 which is about 0.111 or 11.1%.

Finally, we can find the answer to our question: What is the probability that Jon selects a red marble and then a yellow marble?

Because these are independent events (selecting a red marble does not affect the chance of selecting a yellow marble next), we can use the multiplication rule of probability to find the overall probability.

The multiplication rule states that the probability of two independent events both happening is the product of their individual probabilities. So the probability of picking a red marble and then a yellow marble, denoted as P(red and yellow), is P(red) * P(yellow).

P(red and yellow) = P(red) * P(yellow) = 0.611 * 0.111 which results in about 0.0679 or 6.8%.

So, the closest option is about 0.043 or 4.3% which seems to be incorrect as our calculated probability is different. There might be a mistake in the question or the provided options.

y = - [tex]\frac{2}{3}[/tex] x - 2

the equation of a line in ' slope - intercept form ' is

y = mx + c ( m is the slope and c the y- intercept ) calculate m using the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0 , - 2 ) and (x₂ , y₂ ) = A( 6 , - 6 )

m = [tex]\frac{- 6+ 2}{6 - 0}[/tex] = [tex]\frac{-4}{6}[/tex] = - [tex]\frac{2}{3}[/tex]

y -intercept c = - 2 ( from graph )

y = - [tex]\frac{2}{3}[/tex] x - 2

For this case we have the following equation:

[tex]\frac{2}{3}x-\frac{1}{3}= 2 (x + 2)\\[/tex]

If we multiply both sides of the equation by 3 we get:

[tex]2x-1 = 6 (x + 2)[/tex] ---> Multiplication Property of Equality

Applying the distributive property we have:

[tex]2x-1 = 6x + 12[/tex] ---> Distributive Property

Adding 1 on both sides of equality we have:

[tex]2x-1 + 1 = 6x + 12 + 1\\[/tex]

[tex]2x = 6x + 13[/tex] ---> Addition Property of Equality

Subtracting [tex]6x[/tex] on both sides we have:

[tex]-6x + 2x = 6x-6x + 13\\[/tex]

[tex]-4x = 13[/tex] ---> Subtraction Property of Equality

Finally, dividing by -4 on both sides we have:

[tex]\frac{-4x}{-4}= \frac{13}{-4}\\[/tex]

[tex]x = -\frac{13}{4}[/tex]---> Division Property of Equality

Answer:

-30 will be the determinant.

Step-by-step explanation:

We have to find the system determinant of the given matrix

[tex]\begin{bmatrix}2 & 4\\ 3 & -9\end{bmatrix}[/tex]

Determinant will be = 2(-9) - (4 × 3)

                                 = -18 -12

                                = -30

Therefore, as per given options by you in the comments.

option A is the answer.

Every year, Sam will have 103% of the amount from the previous year.

[tex]p\%=\dfrac{p}{100}\\\\103\%=\dfrac{103}{100}=1.03[/tex]

After the first year:

[tex]1.03\cdot\$4,500[/tex]

After the second year:

[tex]1.03\cdot1.03\cdot\$4,500=\$4,500(1.03)^2[/tex]

After the t-th year:

[tex]\$4,500(1.03)^t[/tex]

Therefore we have the inequality:

[tex]\$4,500(1.03)^t\leq\$7,020\ \ \ \ |\text{divide both sides by \$4,500}\\\\(1.03)^t\leq1.56\\\\(1.03)^{15}\approx15.56\\\\\text{therefore}\ t\leq15[/tex]

ANSWER

The correct answer is [tex]m=45,n=12[/tex].

EXPLANATION

We were given the matrix equation;

[tex]\left[\begin{array}{cc}n-1&6\\-19&m+3\end{array}\right] +\left[\begin{array}{cc}-1&0\\16&-8\end{array}\right] =\left[\begin{array}{cc}10&6\\-3&40\end{array}\right][/tex].

We must first simplify the Left Hand Side of the equation by adding corresponding entries.

[tex]\left[\begin{array}{cc}n-1+-1&6+0\\-19+16&m+3-8\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right][/tex].

That is;

[tex]\left[\begin{array}{cc}n-2&6\\-3&m-5\end{array}\right]=\left[\begin{array}{cc}10&6\\-3&40\end{array}\right][/tex].

Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.

This implies that;

[tex]n-2=10[/tex]

We got this equation from row one-column one entry of both matrices.

[tex]n=12[/tex]

Also, the row three-column three entries of both matrices will give us the equation;

[tex]m-5=40[/tex]

[tex]m=45[/tex]

Hence the correct answer is [tex]m=45,n=12[/tex].
