Answer:

well from what I see this is boring

Answer:

no it is not

Step-by-step explanation:

Interest from first account is :

[tex]I_1 = \dfrac{p\times r \times t}{100}\\\\I_1 = \dfrac{509\times 3.4\times 3}{100}\\\\I_1 =\$ 51.918[/tex]

Interest form second account is :

[tex]I_2 = \dfrac{p\times r\times t}{100}\\\\I_2 = \dfrac{509\times 1.7\times 3}{100}\\\\I_2 = \$25.959[/tex]

So, total interest is :

[tex]I = I_1 + I_2 \\\\I = 51.918 + 25.959\\\\I = \$77.877[/tex]

Therefore, total interest is $77.877 .

Answer:

f(-3) = 21

Step-by-step explanation:

To solve this, you can replace all x's with -3 and then solve to find the answer.

f(x) = x^2 - 4x

f(-3) = -3^2 - 4(-3)

f(-3) = 9 - (-12)

f(-3) = 21

I hope this helps!

First blank: 1

Second blank: 7

Third blank: 4

Step-by-step explanation:

I did the division, got the answer as 1.1, so the first blank is 1. The second blank should be 7 and the third blank should be 4 so that the numbers subtract to 0.

Answer: Option A.

Step-by-step explanation:

Simplifying

xy + -9z = 4

Solving

xy + -9z = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9z' to each side of the equation.

xy + -9z + 9z = 4 + 9z

Combine like terms: -9z + 9z = 0

xy + 0 = 4 + 9z

xy = 4 + 9z

Divide each side by 'y'.

x = 4y-1 + 9y-1z

Simplifying

x = 4y-1 + 9y-1z

Answer:

log 4 ( 4096 )  = 6

Step-by-step explanation:

Convert the exponential equation to a logarithmic equation using the logarithm base  ( 4 )  of the right side  ( 4096 )  equals the exponent  ( 6 )

Answer:

Step-by-step explanation:

1/3 - 1/6

2/6 -1/6= 1/6

find common denominator

For  [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]  the fraction will be [tex]\dfrac{1}{6}[/tex] .

Given to us,

[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]

To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.

As we know the LCM of 3 and 6 is 6 itself.

So, multiplying and dividing by 2.

[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]

Now,

[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]

Hence, for  [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]  the fraction will be [tex]\dfrac{1}{6}[/tex] .

Answer:

The approximate probability that a random vehicle is a passenger car is 74.67%

Step-by-step explanation:

Probability

The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.

We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:

[tex]\displaystyle p=\frac{112}{150}[/tex]

p = 0.7467

p = 74.67%

The approximate probability that a random vehicle is a passenger car is 74.67%

Answer:

Please see explanation

Step-by-step explanation:

A system of linear equations in two variables represents two lines on graph.

When both the lines have same slope, there can be two cases

When two lines have same slope and different y-intercepts, that means that both lines are parallel and parallel lines have no solution.

When the slope of both lines is same and the y-intercept is also same, this means that both the equations refer to the same line. This means that the system has infinite number of solutions.

slope = 2

y-int = 3

Step-by-step explanation:

y-intercept can be determined by the coordinate (0,3) which is 3 units up from origin on the y-axis

slope can be determined by taking the difference of a pair of y-values and dividing it by the difference of the x-values

ex,  3 - 1    = 2

     0 - (-1)      1

or:   5 - 3  = 2

Shape 1: 197.04

Shape 2: 125.44

Shape 3: 62.72

Step-by-step explanation:

For shape 1, you first need to find the radius to then find the area of a circle. Which is 394.08. Since this isn't a full circle, you will need to divide it by 2 to get 197.04. For shape 2(Easiest to find) You do 11.2*11.2 to get the answer of 125.44. And lastly for shape 3, you can basically do the same as what you did for shape 2. But since it is a triangle, you divide your answer by 2, to get the answer of 62.72.
