describe how a root ca be written using rational expressions, give an example
Answer:
Given an expression with a rational exponent, write the expression as a radical. Determine the power by looking at the numerator of the exponent. Determine the root by looking at the denominator of the exponent. Using the base as the radicand, raise the radicand to the power and use the root as the index

Use the distributive property to remove the parentheses.
- 4(5u - 3y-1)
Answer:
-20u + 12y + 4
Step-by-step explanation:
We have the equation -4(5u - 3y - 1) and are asked to use the distributive property to remove the parenthesis.
When using the distributive property, you have to multiply the number outside the parenthesis to all numbers inside the parenthesis, do as followed :
-4(5u - 3y - 1)
(5u(-4) -3y(-4) -1(-4))
-20u + 12y + 4

What does AB equal in this problem? It’s timed
Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)

Question 4 of 10
Which of the following is the equation of a line in slope-intercept form for a
line with slope = 5 and y-intercept at (0, -3)?
A. y=-3x + 5
B. x = 3y-5
C. y= 5x + 3
O D. y = 5x - 3
Answer:
d. y=5x-3
Slope-intercept form is y=mx+b.
m= slope
b= y intercept
so, m=5 and b= -3
Substitute with those values and then you have the equation.

The chorus at an elementary school is made up on fifth and sixth graders. This year, the chorus had 12 fifth-grade girls, 9 fifth-grade boys, 14 sixth-grade girls, and 10 sixth-grade boys.
Find the following ratios:
a. The ratio of boys to girls
b. The ratio of fifth graders to sixth graders
c. The ratio of girls to the total number of students in the chorus
Answer:
A: 19:26 B:7:8 C:26:45
Step-by-step explanation:
Question A
First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,
Boys
9+10=19
Girls
12+14=26
Now that you have the total number of boys and girls you make this ratio,
19:26
That is the final answer
Question B
For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,
Fifth Graders
12+9=21
Sixth Graders
14+10=24
Now that you have the total number of both of the different grades you make this ratio,
21:24
You can simplify this by finding the lowest common factor which would be
7:8
Question C
To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.
Girls
12+14=26
All
12+9+14+10=45
Now with the total number of both you will form a ratio
26:45
This is your final answer because you cant simplify this any further

Alison paid $285 for 5similar DVDs and 9similar CDs. Janice paid $225for5similarDVDs and 5 similar CDs. How much did Suzy paid for 5 similar DVDs and six similar CDs
Answer:
$240
Step-by-step explanation:
this would be solved using simultaneous equation
let c = cost of cds
d = cost of dvds
two equatiions can be derived from the question
5d + 9c = 285 eqn 1
5d + 5c = 225 equation 2
subtract equation 2 from 1
4c = 60
c = 15
substitute for c in eqn 1
5d + 9(15) = 285
5d = 150
d = 30
5(30) + 6(15) = 240

A television that has a regular price at $999 is on sale this week for $799. By what percent did the price of the television decrease? What proportion would you use to solve this problem?
A Difference over Original - 100 over x%
B $799 over $999 = x% over 100
C $200 over $999 = x% over 100
D Difference over Total = x% over 100
Answer:
C. $200 over $999 = x% over 100
Step-by-step explanation:
200/999 = 0.2002002002 about 20%
that's how much it decreases since they have a difference of 200.
