If something is negative then it is decreasing. We can express this in terms of velocity per second.

"A car is traveling backwards. What is its velocity if it travels 85 miles in 15 seconds"

This is the easiest word problem I can think of. (When a car travels backwards it has a negative velocity but a positive speed).

The balance in my bank account went down $85 in 15 days. How much did it change per day. Use a positive number to represent a gain of money and a negative number to represent a loss of money.

The change in balance is a loss of money, so the change is -85.

The change of -85 occurred in 15 days, so the average change per day is

-85/15

Four times the larger of two numbers is equal to seven times the smaller the sum of the numbers is 22 find the numbers

Alexus [3.1K]

Answer:

8 and 14

Step-by-step explanation:

X + Y = 22

X= 22-Y

4X= 7Y

4(22-Y) = 7Y

88-4Y=7Y

88= 11Y

8=Y

X= 22-Y= 22-8=14

About 5 out of 10 people entering a community college need to take a refresher mathematics course. If there are 970 entering st

Ksenya-84 [330]

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total = 990

Using the Law of Cosines, in triangle DEF, if e=18yd, d=10yd, f=22yd, find measurement of angle D

Ivahew [28]

Check the picture below.

$\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}
\\\\\\
\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}=cos(C)\implies cos^{-1}\left(\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}\right)=\measuredangle C\\\\
-------------------------------\\\\
\begin{cases}
d=10\\
e=18\\
f=22
\end{cases}\implies cos^{-1}\left(\cfrac{{{ 18}}^2+{{ 22}}^2-10^2}{2(18)(22)}\right)=\measuredangle D$

$\bf \implies cos^{-1}\left(0.893\overline{93}\right)=\measuredangle D\implies 26.63^o\approx \measuredangle D$

A parallelogram with a base of y units and a height of x units is changed to have a new base of 3y units and a height of 2x unit

nataly862011 [7]

The formula for the area of a parallelogram is

A=b*h where b=base and h=height

if the base were to increase by 3times and the height were to increase by 2 times then
6A=b*h
The area of the parallelogram would be 6 times larger

So if the original area was 47units², then the new area would be

47*6=282units²

Answer=282units²

Evaluate the expression:–|20| + |5|

Svetradugi [14.3K]

-|20| + |5| = -15

Steps:
Apply absolute rule: |a| = a, a >/ 0
|20| = 20
= -20+5
Apply absolute rule: |a| = a, a >/ 0
|5| = 5
= -20+5
Refine
= -15

Hope this helps you! (:
