Svetach [21]

Answer:

$51.75

Step-by-step explanation:

Okay, so. They decreased there interest by .15. It is really nothing. So, we have no clue how many years. So, we will just use one year. We would start by multiplying 50 and 3.5% that will equal 1.75. Then we would add it up. 50 + 1.75, it will equal to 51.75.

Therefore your answer is $51.75

Hope this helps!

Can u please help me solve? I'm reviewing for finals.

Black_prince [1.1K]

Given:

Consider the given graph as a reference of the solution.

To find:

$-3(u\cdot v)$

Explanation:

By analyzing the graph, we can define the coordinate of vector u and v:

$\begin{align} & \vec{u}=(-8,-9)-(0,0)=(-8,-9) \\ & \vec{v}=(3,7)-(0,0)=(3,7)\end{align}$

Now, let perform the dot product of two vectors,

$\begin{gathered} u\cdot v=(-8,-9)\cdot(3,7) \\ u\cdot v=(-8)(3)+(-9)(7) \\ u\cdot v=-24-63 \\ u\cdot v=-87 \end{gathered}$

Now, perform the required operation,

$\begin{gathered} -3(u\cdot v) \\ =-3(-87) \\ =261 \end{gathered}$

Final answer:

Hence, the required solution is:

$-3(u\cdot v)=261$

The population of the united states is 280 million. If 2 out of 3 americans know who the vice president is, how many americans k

kotykmax [81]

Answer:

186,666,667 Americans know who the vice president is

Step-by-step explanation:

In this question, we are tasked with calculating the number of USA citizens that know who the vice president is.

Now, in this question, we are made to know that the total population is set at 280 million with 2 out of three knowing who the vice president is.

What this means is that a fraction of the population at 2/3 knows who the vice president is

This fraction is equal to; 2/3 * 280,000,000 = 186,666,666.66666666

This is approximately equal to 186,666,667 people
