Answer:

Step-by-step explanation:

Are the ratios of 2 apples to 5 oranges and 6 apples to 14

oranges equivalent? Why or why not? Explain mathematically.

2 : 5 = 6 : 14

0.4 = 0.42

the equation is false so the answer is no

Answer:

Step-by-step explanation:

Multiplying the 2 and the 5 by 3 will get you 6 and 14. 14 is not a factor of 5 making it incorrect.

Analysis of an accident scene indicates a car was traveling at a velocity of 69.5 mph (31.1 m/s) along the positive x-axis at th

STatiana [176]

We can find the acceleration via

${v_f}^2-{v_i}^2=2a\Delta x$

We have

$\left(5.20\dfrac{\rm m}{\rm s}\right)^2-\left(31.1\dfrac{\rm m}{\rm s}\right)^2=2a(115\,\mathrm m)$

$\implies\boxed{a=-4.09\dfrac{\rm m}{\mathrm s^2}}$

Then by definition of average acceleration,

$a_{\rm ave}=\dfrac{v_f-v_i}t$

so that

$-4.09\dfrac{\rm m}{\mathrm s^2}=\dfrac{5.20\frac{\rm m}{\rm s}-31.1\frac{\rm m}{\rm s}}t$

$\implies\boxed{t=6.33\,\mathrm s}$

We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is

$v_{\rm ave}=\dfrac{x_f-x_i}t=\dfrac{v_f+v_i}2$

Then

$\dfrac{115\,\rm m}t=\dfrac{5.20\frac{\rm m}{\rm s}+31.1\frac{\rm m}{\rm s}}2$

$\implies\boxed{t=6.33\,\mathrm s}$

You can draw a picture of the fence, as a line, and label every centimeter pretending it is a foot, and then draw bushes under the line spread out by 1.5 centimeters. you can then count how many bushes you can put along the fence. you may need a ruler to do this. hope this helps

2. Twenty-four fourth graders are going on a field trip to the Academy of Science. They need to form 3 groups of students for th

Tatiana [17]

Answer:

8persons/group

Step-by-step explanation:

Give parameters:

Number fourth graders = 24

Number of groups = 3 groups

Unknown:

Number of students in each group = ?

Solution:

Solving this problem involves finding the number of persons per group.

Number of persons per group = $\frac{number of fourth graders}{number of groups}$

Insert the parameters and solve;

Number of persons per group = $\frac{24}{3}$ = 8persons/group
