Answer: 5.6%

Step-by-step explanation:

Formula for simple interest: Interest = \dfrac{P\times R \times T}{100}, where P= Principal , R = Rate of interest , T= Time.

Given: P= $3,875, T= 3 years , Interest = $651

Substitute all values in formula, we get

651=\dfrac{3875\times R\times3}{100}\\\\\Rightarrow\ R= \dfrac{65100}{3875\times3}\\\\\Rightarrow\ R=5.6\%

Hence, the required rate = 5.6%

mart [117]

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.

Answer:

19,200 yds²

Step-by-step explanation:

The question is asking for how many <em>square yards</em> of grass is needed

This means that it is looking for the Area.

The formula for area is <em>Length x Width = Area</em>

<em>120</em> (Length)

<em>160</em> (Width)

<em>120 x 160</em> = 19,200

The unit of measurement is yards...

19,200 yds²

Suppose j varies jointly with g and v, and j=1 when g=4 and v=5. what is j when g=10 and v=9?
Tems11 [23]
J\alpha gv
j=agv where a is a constant of proportionality.
j=1 when g=4 and v=5
1=a*4*5
1=20a
a=1/20
a= 0.05
j=0.05gv
When g=10 and v=9,
j=0.05*10*9
j=0.5*9
j=4.5

Alex787 [66]

Answer:

9.8

Step-by-step explanation:

Given that a survey of sports fan was conducted counting no of persons whose favourite was football, baseball, basketball and hockey.

Given that 49 like football, 35 baseball, 11 basket ball and 5 hockey

We have to find ratio of football fans to hockey fans.

We find that hockey fans are 5 and football fans are 49

Ratio of football fans to hockey fans =49/5

=9.80

The ratio means if 9.80 football favourite persons are there there would be only one person whose favourite is hockey.
