Parallelogram P Q S R is shown. The length of P Q is (2 x + 5) centimeters and the length of R S is (4 x + 1) centimeters. In parallelogram PQSR, what is PQ? 2 cm 5 cm 6 cm 9 cm
Answer:
9cm
Step-by-step explanation:
Opposite sides of a parallelogram are parallel (congruent). This shows that
PQ = RS
2x+5 = 4x+1
2x-4x = 1-5
-2x = -4
x = -4/-2
x = 2
Get PQ
PQ = 2x+5
PQ = 2(2)+5
PQ = 4+5
PQ = 9cm
Answer:
9cm

Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 12 2/5 hours and also earned some tips. Her final pay for the week was $159.50. How much money did Yolanda earn in tips?
Answer:
She earned $20 in tips.
Step-by-step explanation:
First, you need to work out how much pay she'd get for 12 hours work:
12 x $11.25 = $135 for 12 hours work
Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50
Add both these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
Subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = $20

Answer:
-11/12
Step-by-step explanation:
Answer:
-11
12
Step-by-step explanation:
You have to add the numbers, multiply them, subtract them and then finally divide.
5n + 2n + 6 = 4n - 21
5n+2n+6=4n-21 group like terms on left side
7n+6=4n-21subtract 6 from both sides
7n=4n-27 subtract 4n from both sides
3n=27 divide both sides by 3
n=9

What is the probability that a student who plays an instrument is in band
Answer:
20/25
Step-by-step explanation:
Here, we want to calculate the probability that a student who plays an instrument is in band
The number of students who play instruments are;
25
Amongst this,
20 are in a band
So the probability of having a student who plays instrument and is in a band will be;
20/25 = 4/5

Answer:
x = 7; y = 11
Step-by-step explanation:
AB = x
AB = CD
CD = 7 so....
x = 7
AD = y + x
AD = BC
BC = 18 so...
y + x = 18
y + 7 = 18 subtract 7 from 18
y = 11
Answer:
x = 7
y = 11
Step-by-step explanation:
Do you see those little arrow marks? Those indicate that if a side has those marks, they have the same length. If a side with one arrow is 7 units long, then it means that x = 7, because the side with x also has one arrow. Then, just plug in 7 into the y+x equation, and set it equal to the other side. (18).
y + 7 = 18; subtract 7 from both sides, to get x = 7; y = 11.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

if 10^3x=1/0.001,find the value of x
Answer:
x = 1
Step-by-step explanation:
Firstly, look at the left hand of the equation
1/0.001 = 1000 = 10^3
then
10^3x = 1000= 10^3
then
10^3x = 10^3
then
x= 1

A storekeeper increased the price of hats by 5%.
Write an equation to calculate the increase of the total
cost, c, when the price of a hat is p dollars.
Select all that apply.
A c 1.50p
BC-,95p
cc 1.05p
Dc-1 + 05p
Ec-(1 + .05)p
Answer: c = 1.05p
Step-by-step explanation:
Price of the hat = p
Percentage increase in the price of the hat = 5%
The equation to calculate the increase of the total cost, c, of the hat will be:
c = p + (5% × p)
= p + (5/100 × p)
= p + (0.05 × p)
= p + 0.05p
c = 1.05p
An object moves such that acceleration a(t)=2(1-3t). Given v(0)=-5 and x(0)=4, find x(1).
I know the answer is -1, just not too sure on how to get the work, thanks!
Answer:
x(1) = -1
Step-by-step explanation:
Given the equation for acceleration of the object as;
a(t)=2(1-3t)
a(t) = 2-6t
Integrate to get the velocity
v(t) = 2t-6t²/2 + C
v(t) = 2t-3t²+C
If v(0) = -5
when t = 0 v = -5
-5 = 2(0)-3(0)²+C
-5 = C
C = -5
v(t) = 2t-3t²-5
To get the displacement x(t), we will integrate the velocity function
x(t) = 2t²/2-3t³/3-5t+C
x(t) = t²-t³-5t+C
If x(0) = 4
At t = 0, x(t) = 4
4 = 0²-0³-5(0)+C
4 = C
C = 4
x(t) = t²-t³-5t+4
Get x(1)
x(1) = 1²-1³-5(1)+4
x(1) = 1-1-5+4
x(1) = -5+4
x(1) = -1
Hence x(1) = -1
Select all that apply.
Which representations show a direct variation?
y = - x
y = 2 x + 3
Input (x) 3 6 9 12 15
Output (y) 4 8 12 16 20
Answer:
Options 1 and 3 are direct variationStep-by-step explanation:
Direct variation is:
y = kxOptions:
1.
y = -x, k = -1, yes2.
y = 2x + 3, not a direct variation, no3.
Try the input/output to determine the direct variation:
4 = 3k k = 4/3Verify the other pairs:
x = 6, y = 6(4/3) = 8x = 9, y = 9(4/3) = 12x = 12, y = 12(4/3) = 16x = 15, y = 15(4/3) = 20This is also a direct variation

How do you write the algebraic expression 6 less than the quotient of 32 and a number y
Answer:
( 32/y ) - 6
Step-by-step explanation:
okay so quotient means the result obtained by dividing one quantity by another and the problem that follows that is 32 and a number, y
this is meaning that 32 and y and going to be dividing (32/y)
less than means subtraction and the number that's surrounding that is 6.
this means that 6 is going to be subtracted from (32/y)
hopefully this helped! good luck bud <3
